Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

In subr_ndis.c, when searching for keys in our make-pretend registry, make the key name matching case-insensitive. There are some drivers and .inf files that have mismatched cases, e.g. the driver will look for "AdhocBand" whereas the .inf file specifies a registry key to be created called "AdHocBand." The mismatch is probably a typo that went undetected (so much for QA), but since Windows seems to be case-insensitive, we should be too. In if_ndis.c, initialize rates and channels correctly so that specify frequences correctly when trying to set channels in the 5Ghz band, and so that 802.11b rates show up for some a/b/g cards (which otherwise appear to have no 802.11b modes). Also, when setting OID_802_11_CONFIGURATION in ndis_80211_setstate(), provide default values for the beacon interval, ATIM window and dwelltime. The Atheros "Aries" driver will crash if you try to select ad-hoc mode and leave the beacon interval set to 0: it blindly uses this value and does a division by 0 in the interrupt handler, causing an integer divide trap.

Implement some more NDIS and ntoskrnl API calls: subr_ndis.c: NdisGetCurrentSystemTime() which, according to the Microsoft documentation returns "the number of 100 nanosecond intervals since January 1, 1601." I have no idea what's so special about that epoch or why they chose 100 nanosecond ticks. I don't know the proper offset to convert nanotime() from the UNIX epoch to January 1, 1601, so for now I'm just doing the unit convertion to 100s of nanoseconds. subr_ntoskrnl.c: memcpy(), memset(), ExInterlockedPopEntrySList(), ExInterlockedPushEntrySList(). The latter two are different from InterlockedPopEntrySList() and InterlockedPushEntrySList() in that they accept a spinlock to hold while executing, whereas the non-Ex routines use a lock internal to ntoskrnl. I also modified ExInitializePagedLookasideList() and ExInitializeNPagedLookasideList() to initialize mutex locks within the lookaside structures. It seems that in NDIS 5.0, the lookaside allocate/free routines ExInterlockedPopEntrySList() and ExInterlockedPushEntrySList(), which require the use of the per-lookaside spinlock, whereas in NDIS 5.1, the per-lookaside spinlock is deprecated. We need to support both cases. Note that I appear to be doing something wrong with ExInterlockedPopEntrySList() and ExInterlockedPushEntrySList(): they don't appear to obtain proper pointers to their arguments, so I'm probably doing something wrong in terms of their calling convention (they're declared to be FASTCALL in Widnows, and I'm not sure what that means for gcc). It happens that in my stub lookaside implementation, they don't need to do any work anyway, so for now I've hacked them to always return NULL, which avoids corrupting the stack. I need to do this right though.

Back out the last batch of changes until I have a chance to properly evaluate them. Whatever they're meant to do, they're doing it wrong. Also: - Clean up last bits of NULL fallout in subr_pe - Don't let ndis_ifmedia_sts() do anything if the IFF_UP flag isn't set - Implement NdisSystemProcessorCount() and NdisQueryMapRegisterCount().

Implement NdisScheduleWorkItem() and RtlCompareMemory(). Also, call the libinit and libfini routines from the modevent handler in kern_ndis.c. This simplifies the initialization a little.

#include <sys/queue.h>
Implement NdisOpenFile()/NdisCloseFile()/NdisMapFile()/NdisUnmapFile(). By default, we search for files in /compat/ndis. This can be changed with a systcl. These routines are used by some drivers which need to download firmware or microcode into their respective devices during initialization. Also, remove extraneous newlines from the 'built-in' sysctl/registry variables.

#include <sys/proc.h>
Implement support for single packet sends. The Intel Centrino driver that Asus provides on its CDs has both a MiniportSend() routine and a MiniportSendPackets() function. The Microsoft NDIS docs say that if a driver has both, only the MiniportSendPackets() routine will be used. Although I think I implemented the support correctly, calling the MiniportSend() routine seems to result in no packets going out on the air, even though no error status is returned. The MiniportSendPackets() function does work though, so at least in this case it doesn't matter. In if_ndis.c:ndis_getstate_80211(), if ndis_get_assoc() returns an error, don't bother trying to obtain any other state since the calls may fail, or worse cause the underlying driver to crash. (The above two changes make the Asus-supplied Centrino work.) Also, when calling the OID_802_11_CONFIGURATION OID, remember to initialize the structure lengths correctly. In subr_ndis.c:ndis_open_file(), set the current working directory to rootvnode if we're in a thread that doesn't have a current working directory set.

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

#include <sys/kthread.h>
Big mess 'o changes: - Give ndiscvt(8) the ability to process a .SYS file directly into a .o file so that we don't have to emit big messy char arrays into the ndis_driver_data.h file. This behavior is currently optional, but may become the default some day. - Give ndiscvt(8) the ability to turn arbitrary files into .ko files so that they can be pre-loaded or kldloaded. (Both this and the previous change involve using objcopy(1)). - Give NdisOpenFile() the ability to 'read' files out of kernel memory that have been kldloaded or pre-loaded, and disallow the use of the normal vn_open() file opening method during bootstrap (when no filesystems have been mounted yet). Some people have reported that kldloading if_ndis.ko works fine when the system is running multiuser but causes a panic when the modile is pre-loaded by /boot/loader. This happens with drivers that need to use NdisOpenFile() to access external files (i.e. firmware images). NdisOpenFile() won't work during kernel bootstrapping because no filesystems have been mounted. To get around this, you can now do the following: o Say you have a firmware file called firmware.img o Do: ndiscvt -f firmware.img -- this creates firmware.img.ko o Put the firmware.img.ko in /boot/kernel o add firmware.img_load="YES" in /boot/loader.conf o add if_ndis_load="YES" and ndis_load="YES" as well Now the loader will suck the additional file into memory as a .ko. The phony .ko has two symbols in it: filename_start and filename_end, which are generated by objcopy(1). ndis_open_file() will traverse each module in the module list looking for these symbols and, if it finds them, it'll use them to generate the file mapping address and length values that the caller of NdisOpenFile() wants. As a bonus, this will even work if the file has been statically linked into the kernel itself, since the "kernel" module is searched too. (ndiscvt(8) will generate both filename.o and filename.ko for you). - Modify the mechanism used to provide make-pretend FASTCALL support. Rather than using inline assembly to yank the first two arguments out of %ecx and %edx, we now use the __regparm__(3) attribute (and the __stdcall__ attribute) and use some macro magic to re-order the arguments and provide dummy arguments as needed so that the arguments passed in registers end up in the right place. Change taken from DragonflyBSD version of the NDISulator.

Use atomic ops for the interlocked increment and decrement routines in subr_ndis and subr_ntoskrnl. This is faster and avoids potential LOR whinage from witness (an LOR couldn't happen with the old code since the interlocked inc/dec routines could not sleep with a lock held, but this will keep witness happy and it's more efficient anyway. I think.)

Big round of updates: - Make ndis_get_info()/ndis_set_info() sleep on the setdone/getdone routines if they get back NDIS_STATUS_PENDING. - Add a bunch of net80211 support so that 802.11 cards can be twiddled with ifconfig. This still needs more work and is not guaranteed to work for everyone. It works on my 802.11b/g card anyway. The problem here is Microsoft doesn't provide a good way to a) learn all the rates that a card supports (if it has more than 8, you're kinda hosed) and b) doesn't provide a good way to distinguish between 802.11b, 802.11b/g an 802.11a/b/g cards, so you sort of have to guess. Setting the SSID and switching between infrastructure/adhoc modes should work. WEP still needs to be implemented. I can't find any API for getting/setting the channel other than the registry/sysctl keys.

The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Continue my efforts to imitate Windows as closely as possible by attempting to duplicate Windows spinlocks. Windows spinlocks differ from FreeBSD spinlocks in the way they block preemption. FreeBSD spinlocks use critical_enter(), which masks off _all_ interrupts. This prevents any other threads from being scheduled, but it also prevents ISRs from running. In Windows, preemption is achieved by raising the processor IRQL to DISPATCH_LEVEL, which prevents other threads from preempting you, but does _not_ prevent device ISRs from running. (This is essentially what Solaris calls dispatcher locks.) The Windows spinlock itself (kspin_lock) is just an integer value which is atomically set when you acquire the lock and atomically cleared when you release it. FreeBSD doesn't have IRQ levels, so we have to cheat a little by using thread priorities: normal thread priority is PASSIVE_LEVEL, lowest interrupt thread priority is DISPATCH_LEVEL, highest thread priority is DEVICE_LEVEL (PI_REALTIME) and critical_enter() is HIGH_LEVEL. In practice, only PASSIVE_LEVEL and DISPATCH_LEVEL matter to us. The immediate benefit of all this is that I no longer have to rely on a mutex pool. Now, I'm sure many people will be seized by the urge to criticize me for doing an end run around our own spinlock implementation, but it makes more sense to do it this way. Well, it does to me anyway. Overview of the changes: - Properly implement hal_lock(), hal_unlock(), hal_irql(), hal_raise_irql() and hal_lower_irql() so that they more closely resemble their Windows counterparts. The IRQL is determined by thread priority. - Make ntoskrnl_lock_dpc() and ntoskrnl_unlock_dpc() do what they do in Windows, which is to atomically set/clear the lock value. These routines are designed to be called from DISPATCH_LEVEL, and are actually half of the work involved in acquiring/releasing spinlocks. - Add FASTCALL1(), FASTCALL2() and FASTCALL3() macros/wrappers that allow us to call a _fastcall function in spite of the fact that our version of gcc doesn't support __attribute__((__fastcall__)) yet. The macros take 1, 2 or 3 arguments, respectively. We need to call hal_lock(), hal_unlock() etc... ourselves, but can't really invoke the function directly. I could have just made the underlying functions native routines and put _fastcall wrappers around them for the benefit of Windows binaries, but that would create needless bloat. - Remove ndis_mtxpool and all references to it. We don't need it anymore. - Re-implement the NdisSpinLock routines so that they use hal_lock() and friends like they do in Windows. - Use the new spinlock methods for handling lookaside lists and linked list updates in place of the mutex locks that were there before. - Remove mutex locking from ndis_isr() and ndis_intrhand() since they're already called with ndis_intrmtx held in if_ndis.c. - Put ndis_destroy_lock() code under explicit #ifdef notdef/#endif. It turns out there are some drivers which stupidly free the memory in which their spinlocks reside before calling ndis_destroy_lock() on them (touch-after-free bug). The ADMtek wireless driver is guilty of this faux pas. (Why this doesn't clobber Windows I have no idea.) - Make NdisDprAcquireSpinLock() and NdisDprReleaseSpinLock() into real functions instead of aliasing them to NdisAcaquireSpinLock() and NdisReleaseSpinLock(). The Dpr routines use KeAcquireSpinLockAtDpcLevel() level and KeReleaseSpinLockFromDpcLevel(), which acquires the lock without twiddling the IRQL. - In ndis_linksts_done(), do _not_ call ndis_80211_getstate(). Some drivers may call the status/status done callbacks as the result of setting an OID: ndis_80211_getstate() gets OIDs, which means we might cause the driver to recursively access some of its internal structures unexpectedly. The ndis_ticktask() routine will call ndis_80211_getstate() for us eventually anyway. - Fix the channel setting code a little in ndis_80211_setstate(), and initialize the channel to IEEE80211_CHAN_ANYC. (The Microsoft spec says you're not supposed to twiddle the channel in BSS mode; I may need to enforce this later.) This fixes the problems I was having with the ADMtek adm8211 driver: we were setting the channel to a non-standard default, which would cause it to fail to associate in BSS mode. - Use hal_raise_irql() to raise our IRQL to DISPATCH_LEVEL when calling certain miniport routines, per the Microsoft documentation. I think that's everything. Hopefully, other than fixing the ADMtek driver, there should be no apparent change in behavior.

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch.

Continue my efforts to imitate Windows as closely as possible by attempting to duplicate Windows spinlocks. Windows spinlocks differ from FreeBSD spinlocks in the way they block preemption. FreeBSD spinlocks use critical_enter(), which masks off _all_ interrupts. This prevents any other threads from being scheduled, but it also prevents ISRs from running. In Windows, preemption is achieved by raising the processor IRQL to DISPATCH_LEVEL, which prevents other threads from preempting you, but does _not_ prevent device ISRs from running. (This is essentially what Solaris calls dispatcher locks.) The Windows spinlock itself (kspin_lock) is just an integer value which is atomically set when you acquire the lock and atomically cleared when you release it. FreeBSD doesn't have IRQ levels, so we have to cheat a little by using thread priorities: normal thread priority is PASSIVE_LEVEL, lowest interrupt thread priority is DISPATCH_LEVEL, highest thread priority is DEVICE_LEVEL (PI_REALTIME) and critical_enter() is HIGH_LEVEL. In practice, only PASSIVE_LEVEL and DISPATCH_LEVEL matter to us. The immediate benefit of all this is that I no longer have to rely on a mutex pool. Now, I'm sure many people will be seized by the urge to criticize me for doing an end run around our own spinlock implementation, but it makes more sense to do it this way. Well, it does to me anyway. Overview of the changes: - Properly implement hal_lock(), hal_unlock(), hal_irql(), hal_raise_irql() and hal_lower_irql() so that they more closely resemble their Windows counterparts. The IRQL is determined by thread priority. - Make ntoskrnl_lock_dpc() and ntoskrnl_unlock_dpc() do what they do in Windows, which is to atomically set/clear the lock value. These routines are designed to be called from DISPATCH_LEVEL, and are actually half of the work involved in acquiring/releasing spinlocks. - Add FASTCALL1(), FASTCALL2() and FASTCALL3() macros/wrappers that allow us to call a _fastcall function in spite of the fact that our version of gcc doesn't support __attribute__((__fastcall__)) yet. The macros take 1, 2 or 3 arguments, respectively. We need to call hal_lock(), hal_unlock() etc... ourselves, but can't really invoke the function directly. I could have just made the underlying functions native routines and put _fastcall wrappers around them for the benefit of Windows binaries, but that would create needless bloat. - Remove ndis_mtxpool and all references to it. We don't need it anymore. - Re-implement the NdisSpinLock routines so that they use hal_lock() and friends like they do in Windows. - Use the new spinlock methods for handling lookaside lists and linked list updates in place of the mutex locks that were there before. - Remove mutex locking from ndis_isr() and ndis_intrhand() since they're already called with ndis_intrmtx held in if_ndis.c. - Put ndis_destroy_lock() code under explicit #ifdef notdef/#endif. It turns out there are some drivers which stupidly free the memory in which their spinlocks reside before calling ndis_destroy_lock() on them (touch-after-free bug). The ADMtek wireless driver is guilty of this faux pas. (Why this doesn't clobber Windows I have no idea.) - Make NdisDprAcquireSpinLock() and NdisDprReleaseSpinLock() into real functions instead of aliasing them to NdisAcaquireSpinLock() and NdisReleaseSpinLock(). The Dpr routines use KeAcquireSpinLockAtDpcLevel() level and KeReleaseSpinLockFromDpcLevel(), which acquires the lock without twiddling the IRQL. - In ndis_linksts_done(), do _not_ call ndis_80211_getstate(). Some drivers may call the status/status done callbacks as the result of setting an OID: ndis_80211_getstate() gets OIDs, which means we might cause the driver to recursively access some of its internal structures unexpectedly. The ndis_ticktask() routine will call ndis_80211_getstate() for us eventually anyway. - Fix the channel setting code a little in ndis_80211_setstate(), and initialize the channel to IEEE80211_CHAN_ANYC. (The Microsoft spec says you're not supposed to twiddle the channel in BSS mode; I may need to enforce this later.) This fixes the problems I was having with the ADMtek adm8211 driver: we were setting the channel to a non-standard default, which would cause it to fail to associate in BSS mode. - Use hal_raise_irql() to raise our IRQL to DISPATCH_LEVEL when calling certain miniport routines, per the Microsoft documentation. I think that's everything. Hopefully, other than fixing the ADMtek driver, there should be no apparent change in behavior.

This reduces code duplication and more closely imitates the way things are done in Windows. - Modify ndis_encode_parm() to deal with the case where we have a registry key expressed as a hex value ("0x1") which is being read via NdisReadConfiguration() as an int. Previously, we tried to decode things like "0x1" with strtol() using a base of 10, which would always yield 0. This is what was causing problems with the Intel 2200BG Centrino 802.11g driver: the .inf file that comes with it has a key called RadioEnable with a value of 0x1. We incorrectly decoded this value to '0' when it was queried, hence the driver thought we wanted the radio turned off. - In if_ndis.c, most drivers don't accept NDIS_80211_AUTHMODE_AUTO, but NDIS_80211_AUTHMODE_SHARED may not be right in some cases, so for now always use NDIS_80211_AUTHMODE_OPEN. NOTE: There is still one problem with the Intel 2200BG driver: it happens that the kernel stack in Windows is larger than the kernel stack in FreeBSD. The 2200BG driver sometimes eats up more than 2 pages of stack space, which can lead to a double fault panic. For the moment, I got things to work by adding the following to my kernel config file: options KSTACK_PAGES=8 I'm pretty sure 8 is too big; I just picked this value out of a hat as a test, and it happened to work, so I left it. 4 pages might be enough. Unfortunately, I don't think you can dynamically give a thread a larger stack, so I'm not sure how to handle this short of putting a note in the man page about it and dealing with the flood of mail from people who never read man pages.

Reorganize the timer code a little and implement NdisInitializeTimer() and NdisCancelTimer(). NdisInitializeTimer() doesn't accept an NDIS miniport context argument, so we have to derive it from the timer function context (which is supposed to be the adapter private context). NdisCancelTimer is now an alias for NdisMCancelTimer(). Also add stubs for NdisMRegisterDevice() and NdisMDeregisterDevice(). These are no-ops for now, but will likely get fleshed in once I start working on the Am1771/Am1772 wireless driver.

The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Correct/improve the implementation of NdisMAllocateSharedMemoryAsync(). Since we have a worker thread now, we can actually do the allocation asynchronously in that thread's context. Also, we need to return a status value: if we're unable to queue up the async allocation, we return NDIS_STATUS_FAILURE, otherwise we return NDIS_STATUS_PENDING to indicate the allocation has been queued and will occur later. This replaces the kludge where we just invoked the callback routine right away in the current context.

This should bring us a little closer to getting the Intel centrino wireless NIC to work. Note: I have not actually tested these additions since I don't have a driver that calls them, however they're pretty simple, and one of them is taken pretty much directly from the Windows ndis.h header file, so I'm fairly confident they work, but disclaimers apply.

In if_ndis.c:ndis_attach(), temporarily set the IFF_UP flag while calling the haltfunc. If an interrupt is triggered by the init or halt func, the IFF_UP flag must be set in order for us to be able to service it. In kern_ndis.c: implement a handler for NdisMSendResourcesAvailable() (currently does nothing since we don't really need it). In subr_ndis.c: - Correct ndis_init_string() and ndis_unicode_to_ansi(), which were both horribly broken. - Implement NdisImmediateReadPciSlotInformation() and NdisImmediateWritePciSlotInformation(). - Implement NdisBufferLength(). - Work around my first confirmed NDIS driver bug. The SMC 9462 gigE driver (natsemi 83820-based copper) incorrectly creates a spinlock in its DriverEntry() routine and then destroys it in its MiniportHalt() handler. This is wrong: spinlocks should be created in MiniportInit(). In a Windows environment, this is often not a problem because DriverEntry()/MiniportInit() are called once when the system boots and MiniportHalt() or the shutdown handler is called when the system halts.

There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead.

Implement some more NDIS and ntoskrnl API calls: subr_ndis.c: NdisGetCurrentSystemTime() which, according to the Microsoft documentation returns "the number of 100 nanosecond intervals since January 1, 1601." I have no idea what's so special about that epoch or why they chose 100 nanosecond ticks. I don't know the proper offset to convert nanotime() from the UNIX epoch to January 1, 1601, so for now I'm just doing the unit convertion to 100s of nanoseconds. subr_ntoskrnl.c: memcpy(), memset(), ExInterlockedPopEntrySList(), ExInterlockedPushEntrySList(). The latter two are different from InterlockedPopEntrySList() and InterlockedPushEntrySList() in that they accept a spinlock to hold while executing, whereas the non-Ex routines use a lock internal to ntoskrnl. I also modified ExInitializePagedLookasideList() and ExInitializeNPagedLookasideList() to initialize mutex locks within the lookaside structures. It seems that in NDIS 5.0, the lookaside allocate/free routines ExInterlockedPopEntrySList() and ExInterlockedPushEntrySList(), which require the use of the per-lookaside spinlock, whereas in NDIS 5.1, the per-lookaside spinlock is deprecated. We need to support both cases. Note that I appear to be doing something wrong with ExInterlockedPopEntrySList() and ExInterlockedPushEntrySList(): they don't appear to obtain proper pointers to their arguments, so I'm probably doing something wrong in terms of their calling convention (they're declared to be FASTCALL in Widnows, and I'm not sure what that means for gcc). It happens that in my stub lookaside implementation, they don't need to do any work anyway, so for now I've hacked them to always return NULL, which avoids corrupting the stack. I need to do this right though.

In if_ndis.c:ndis_attach(), temporarily set the IFF_UP flag while calling the haltfunc. If an interrupt is triggered by the init or halt func, the IFF_UP flag must be set in order for us to be able to service it. In kern_ndis.c: implement a handler for NdisMSendResourcesAvailable() (currently does nothing since we don't really need it). In subr_ndis.c: - Correct ndis_init_string() and ndis_unicode_to_ansi(), which were both horribly broken. - Implement NdisImmediateReadPciSlotInformation() and NdisImmediateWritePciSlotInformation(). - Implement NdisBufferLength(). - Work around my first confirmed NDIS driver bug. The SMC 9462 gigE driver (natsemi 83820-based copper) incorrectly creates a spinlock in its DriverEntry() routine and then destroys it in its MiniportHalt() handler. This is wrong: spinlocks should be created in MiniportInit(). In a Windows environment, this is often not a problem because DriverEntry()/MiniportInit() are called once when the system boots and MiniportHalt() or the shutdown handler is called when the system halts. With this stuff in place, this driver now seems to work: ndis0: <SMC EZ Card 1000> port 0xe000-0xe0ff mem 0xda000000-0xda000fff irq 10 at device 9.0 on pci0 ndis0: assign PCI resources... ndis_open_file("FLASH9.hex", 18446744073709551615) ndis0: Ethernet address: 00:04:e2:0e:d3:f0

The _fastcall convention is similar to _stdcall, except the first two available DWORD-sized arguments are passed in %ecx and %edx, respectively. One kludge for this __attribute__ ((regparm(3))), however this isn't entirely right, as it assumes %eax, %ecx and %edx will be used (regparm(2) assumes %eax and %edx). Another kludge is to declare the two fastcall-ed args as local register variables and explicitly assign them to %ecx and %edx, but experimentation showed that gcc would not guard %ecx and %edx against being clobbered. Thus, I came up with a 3rd kludge, which is to use some inline assembly of the form: void *arg1; void *arg2; __asm__("movl %%ecx, %%ecx" : "=c" (arg1)); __asm__("movl %%edx, %%edx" : "=d" (arg2)); This lets gcc know that we're going to reference %ecx and %edx and that it should make an effort not to let it get trampled. This wastes an instruction (movl %reg, %reg is a no-op) but insures proper behavior. It's possible there's a better way to do this though: this is the first time I've used inline assembler in this fashion. The above fixes to ntoskrnl_var.h an subr_ntoskrnl.c make lookaside lists work for the two drivers I have that use them, one of which is an NDIS 5.0 miniport and another which is 5.1.

Note: I have not actually tested these additions since I don't have a driver that calls them, however they're pretty simple, and one of them is taken pretty much directly from the Windows ndis.h header file, so I'm fairly confident they work, but disclaimers apply.

Big mess 'o changes: - Give ndiscvt(8) the ability to process a .SYS file directly into a .o file so that we don't have to emit big messy char arrays into the ndis_driver_data.h file. This behavior is currently optional, but may become the default some day. - Give ndiscvt(8) the ability to turn arbitrary files into .ko files so that they can be pre-loaded or kldloaded. (Both this and the previous change involve using objcopy(1)). - Give NdisOpenFile() the ability to 'read' files out of kernel memory that have been kldloaded or pre-loaded, and disallow the use of the normal vn_open() file opening method during bootstrap (when no filesystems have been mounted yet). Some people have reported that kldloading if_ndis.ko works fine when the system is running multiuser but causes a panic when the modile is pre-loaded by /boot/loader. This happens with drivers that need to use NdisOpenFile() to access external files (i.e. firmware images). NdisOpenFile() won't work during kernel bootstrapping because no filesystems have been mounted. To get around this, you can now do the following: o Say you have a firmware file called firmware.img o Do: ndiscvt -f firmware.img -- this creates firmware.img.ko o Put the firmware.img.ko in /boot/kernel o add firmware.img_load="YES" in /boot/loader.conf o add if_ndis_load="YES" and ndis_load="YES" as well Now the loader will suck the additional file into memory as a .ko. The phony .ko has two symbols in it: filename_start and filename_end, which are generated by objcopy(1). ndis_open_file() will traverse each module in the module list looking for these symbols and, if it finds them, it'll use them to generate the file mapping address and length values that the caller of NdisOpenFile() wants. As a bonus, this will even work if the file has been statically linked into the kernel itself, since the "kernel" module is searched too. (ndiscvt(8) will generate both filename.o and filename.ko for you). - Modify the mechanism used to provide make-pretend FASTCALL support. Rather than using inline assembly to yank the first two arguments out of %ecx and %edx, we now use the __regparm__(3) attribute (and the __stdcall__ attribute) and use some macro magic to re-order the arguments and provide dummy arguments as needed so that the arguments passed in registers end up in the right place. Change taken from DragonflyBSD version of the NDISulator.

Back out the last batch of changes until I have a chance to properly evaluate them. Whatever they're meant to do, they're doing it wrong. Also: - Clean up last bits of NULL fallout in subr_pe - Don't let ndis_ifmedia_sts() do anything if the IFF_UP flag isn't set - Implement NdisSystemProcessorCount() and NdisQueryMapRegisterCount().

In ndis_attach(), report the NDIS API level that the Windows miniport driver was compiled with. Remove debug printf from ndis_assicn_pcirsc(). It doesn't serve much purpose. Implement NdisMIndicateStatus() and NdisMIndicateStatusComplete() as functions in subr_ndis.c. In NDIS 4.0, they were functions. In NDIS 5.0 and later, they're just macros. Allocate a few extra packets/buffers beyond what the driver asks for since sometimes it seems they can lie about how many they really need, and some extra stupid ones don't check to see if NdisAllocatePacket() and/or NdisAllocateBuffer() actually succeed.

Convert from using taskqueue_swi to using private kernel threads. The problem with using taskqueue_swi is that some of the things we defer into threads might block for up to several seconds. This is an unfriendly thing to do to taskqueue_swi, since it is assumed the taskqueue threads will execute fairly quickly once a task is submitted. Reorganized the locking in if_ndis.c in the process. Cleaned up ndis_write_cfg() and ndis_decode_parm() a little.

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes.

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes.

Fix the problem with the Cisco Aironet 340 PCMCIA card. Most newer drivers for Windows are deserialized miniports. Such drivers maintain their own queues and do their own locking. This particular driver is not deserialized though, and we need special support to handle it correctly. Typically, in the ndis_rxeof() handler, we pass all incoming packets directly to (*ifp->if_input)(). This in turn may cause another thread to run and preempt us, and the packet may actually be processed and then released before we even exit the ndis_rxeof() routine. The problem with this is that releasing a packet calls the ndis_return_packet() function, which hands the packet and its buffers back to the driver. Calling ndis_return_packet() before ndis_rxeof() returns will screw up the driver's internal queues since, not being deserialized, it does no locking. To avoid this problem, if we detect a serialized driver (by checking the attribute flags passed to NdisSetAttributesEx(), we use an alternate ndis_rxeof() handler, ndis_rxeof_serial(), which puts the call to (*ifp->if_input)() on the NDIS SWI work queue. This guarantees the packet won't be processed until after ndis_rxeof_serial() returns. Note that another approach is to always copy the packet data into another mbuf and just let the driver retain ownership of the ndis_packet structure (ndis_return_packet() never needs to be called in this case). I'm not sure which method is faster.

- Rewrite the timer and event API routines in subr_ndis.c so that they are actually layered on top of the KeTimer API in subr_ntoskrnl.c, just as it is in Windows. This reduces code duplication and more closely imitates the way things are done in Windows. - Modify ndis_encode_parm() to deal with the case where we have a registry key expressed as a hex value ("0x1") which is being read via NdisReadConfiguration() as an int. Previously, we tried to decode things like "0x1" with strtol() using a base of 10, which would always yield 0. This is what was causing problems with the Intel 2200BG Centrino 802.11g driver: the .inf file that comes with it has a key called RadioEnable with a value of 0x1. We incorrectly decoded this value to '0' when it was queried, hence the driver thought we wanted the radio turned off. - In if_ndis.c, most drivers don't accept NDIS_80211_AUTHMODE_AUTO, but NDIS_80211_AUTHMODE_SHARED may not be right in some cases, so for now always use NDIS_80211_AUTHMODE_OPEN. NOTE: There is still one problem with the Intel 2200BG driver: it happens that the kernel stack in Windows is larger than the kernel stack in FreeBSD. The 2200BG driver sometimes eats up more than 2 pages of stack space, which can lead to a double fault panic. For the moment, I got things to work by adding the following to my kernel config file: options KSTACK_PAGES=8 I'm pretty sure 8 is too big; I just picked this value out of a hat as a test, and it happened to work, so I left it. 4 pages might be enough. Unfortunately, I don't think you can dynamically give a thread a larger stack, so I'm not sure how to handle this short of putting a note in the man page about it and dealing with the flood of mail from people who never read man pages.

This reduces code duplication and more closely imitates the way things are done in Windows. - Modify ndis_encode_parm() to deal with the case where we have a registry key expressed as a hex value ("0x1") which is being read via NdisReadConfiguration() as an int. Previously, we tried to decode things like "0x1" with strtol() using a base of 10, which would always yield 0. This is what was causing problems with the Intel 2200BG Centrino 802.11g driver: the .inf file that comes with it has a key called RadioEnable with a value of 0x1. We incorrectly decoded this value to '0' when it was queried, hence the driver thought we wanted the radio turned off. - In if_ndis.c, most drivers don't accept NDIS_80211_AUTHMODE_AUTO, but NDIS_80211_AUTHMODE_SHARED may not be right in some cases, so for now always use NDIS_80211_AUTHMODE_OPEN. NOTE: There is still one problem with the Intel 2200BG driver: it happens that the kernel stack in Windows is larger than the kernel stack in FreeBSD. The 2200BG driver sometimes eats up more than 2 pages of stack space, which can lead to a double fault panic. For the moment, I got things to work by adding the following to my kernel config file: options KSTACK_PAGES=8 I'm pretty sure 8 is too big; I just picked this value out of a hat as a test, and it happened to work, so I left it. 4 pages might be enough. Unfortunately, I don't think you can dynamically give a thread a larger stack, so I'm not sure how to handle this short of putting a note in the man page about it and dealing with the flood of mail from people who never read man pages.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Make NdisReadPcmciaAttributeMemory() and NdisWritePcmciaAttributeMemory() actually work. Make the PCI and PCCARD attachments provide a bus_get_resource_list() method so that resource listing for PCCARD works. PCCARD does not have a bus_get_resource_list() method (yet), so I faked up the resource list management in if_ndis_pccard.c, and added bus_get_resource_list() methods to both if_ndis_pccard.c and if_ndis_pci.c. The one in the PCI attechment just hands off to the PCI bus code. The difference is transparent to the NDIS resource handler code. Fixed ndis_open_file() so that opening files which live on NFS filesystems work: pass an actual ucred structure to VOP_GETATTR() (NFS explodes if the ucred structure is NOCRED). Make NdisMMapIoSpace() handle mapping of PCMCIA attribute memory resources correctly. Turn subr_ndis.c:my_strcasecmp() into ndis_strcasecmp() and export it so that if_ndis_pccard.c can use it, and junk the other copy of my_strcasecmp() from if_ndis_pccard.c.

In subr_ndis.c, when searching for keys in our make-pretend registry, make the key name matching case-insensitive. There are some drivers and .inf files that have mismatched cases, e.g. the driver will look for "AdhocBand" whereas the .inf file specifies a registry key to be created called "AdHocBand." The mismatch is probably a typo that went undetected (so much for QA), but since Windows seems to be case-insensitive, we should be too. In if_ndis.c, initialize rates and channels correctly so that specify frequences correctly when trying to set channels in the 5Ghz band, and so that 802.11b rates show up for some a/b/g cards (which otherwise appear to have no 802.11b modes). Also, when setting OID_802_11_CONFIGURATION in ndis_80211_setstate(), provide default values for the beacon interval, ATIM window and dwelltime. The Atheros "Aries" driver will crash if you try to select ad-hoc mode and leave the beacon interval set to 0: it blindly uses this value and does a division by 0 in the interrupt handler, causing an integer divide trap.

Big mess 'o changes: - Give ndiscvt(8) the ability to process a .SYS file directly into a .o file so that we don't have to emit big messy char arrays into the ndis_driver_data.h file. This behavior is currently optional, but may become the default some day. - Give ndiscvt(8) the ability to turn arbitrary files into .ko files so that they can be pre-loaded or kldloaded. (Both this and the previous change involve using objcopy(1)). - Give NdisOpenFile() the ability to 'read' files out of kernel memory that have been kldloaded or pre-loaded, and disallow the use of the normal vn_open() file opening method during bootstrap (when no filesystems have been mounted yet). Some people have reported that kldloading if_ndis.ko works fine when the system is running multiuser but causes a panic when the modile is pre-loaded by /boot/loader. This happens with drivers that need to use NdisOpenFile() to access external files (i.e. firmware images). NdisOpenFile() won't work during kernel bootstrapping because no filesystems have been mounted. To get around this, you can now do the following: o Say you have a firmware file called firmware.img o Do: ndiscvt -f firmware.img -- this creates firmware.img.ko o Put the firmware.img.ko in /boot/kernel o add firmware.img_load="YES" in /boot/loader.conf o add if_ndis_load="YES" and ndis_load="YES" as well Now the loader will suck the additional file into memory as a .ko. The phony .ko has two symbols in it: filename_start and filename_end, which are generated by objcopy(1). ndis_open_file() will traverse each module in the module list looking for these symbols and, if it finds them, it'll use them to generate the file mapping address and length values that the caller of NdisOpenFile() wants. As a bonus, this will even work if the file has been statically linked into the kernel itself, since the "kernel" module is searched too. (ndiscvt(8) will generate both filename.o and filename.ko for you). - Modify the mechanism used to provide make-pretend FASTCALL support. Rather than using inline assembly to yank the first two arguments out of %ecx and %edx, we now use the __regparm__(3) attribute (and the __stdcall__ attribute) and use some macro magic to re-order the arguments and provide dummy arguments as needed so that the arguments passed in registers end up in the right place. Change taken from DragonflyBSD version of the NDISulator.

There are some drivers and .inf files that have mismatched cases, e.g. the driver will look for "AdhocBand" whereas the .inf file specifies a registry key to be created called "AdHocBand." The mismatch is probably a typo that went undetected (so much for QA), but since Windows seems to be case-insensitive, we should be too. In if_ndis.c, initialize rates and channels correctly so that specify frequences correctly when trying to set channels in the 5Ghz band, and so that 802.11b rates show up for some a/b/g cards (which otherwise appear to have no 802.11b modes). Also, when setting OID_802_11_CONFIGURATION in ndis_80211_setstate(), provide default values for the beacon interval, ATIM window and dwelltime. The Atheros "Aries" driver will crash if you try to select ad-hoc mode and leave the beacon interval set to 0: it blindly uses this value and does a division by 0 in the interrupt handler, causing an integer divide trap.

Big mess 'o changes: - Give ndiscvt(8) the ability to process a .SYS file directly into a .o file so that we don't have to emit big messy char arrays into the ndis_driver_data.h file. This behavior is currently optional, but may become the default some day. - Give ndiscvt(8) the ability to turn arbitrary files into .ko files so that they can be pre-loaded or kldloaded. (Both this and the previous change involve using objcopy(1)). - Give NdisOpenFile() the ability to 'read' files out of kernel memory that have been kldloaded or pre-loaded, and disallow the use of the normal vn_open() file opening method during bootstrap (when no filesystems have been mounted yet). Some people have reported that kldloading if_ndis.ko works fine when the system is running multiuser but causes a panic when the modile is pre-loaded by /boot/loader. This happens with drivers that need to use NdisOpenFile() to access external files (i.e. firmware images). NdisOpenFile() won't work during kernel bootstrapping because no filesystems have been mounted. To get around this, you can now do the following: o Say you have a firmware file called firmware.img o Do: ndiscvt -f firmware.img -- this creates firmware.img.ko o Put the firmware.img.ko in /boot/kernel o add firmware.img_load="YES" in /boot/loader.conf o add if_ndis_load="YES" and ndis_load="YES" as well Now the loader will suck the additional file into memory as a .ko. The phony .ko has two symbols in it: filename_start and filename_end, which are generated by objcopy(1). ndis_open_file() will traverse each module in the module list looking for these symbols and, if it finds them, it'll use them to generate the file mapping address and length values that the caller of NdisOpenFile() wants. As a bonus, this will even work if the file has been statically linked into the kernel itself, since the "kernel" module is searched too. (ndiscvt(8) will generate both filename.o and filename.ko for you). - Modify the mechanism used to provide make-pretend FASTCALL support. Rather than using inline assembly to yank the first two arguments out of %ecx and %edx, we now use the __regparm__(3) attribute (and the __stdcall__ attribute) and use some macro magic to re-order the arguments and provide dummy arguments as needed so that the arguments passed in registers end up in the right place. Change taken from DragonflyBSD version of the NDISulator.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

In if_ndis.c:ndis_attach(), temporarily set the IFF_UP flag while calling the haltfunc. If an interrupt is triggered by the init or halt func, the IFF_UP flag must be set in order for us to be able to service it. In kern_ndis.c: implement a handler for NdisMSendResourcesAvailable() (currently does nothing since we don't really need it). In subr_ndis.c: - Correct ndis_init_string() and ndis_unicode_to_ansi(), which were both horribly broken. - Implement NdisImmediateReadPciSlotInformation() and NdisImmediateWritePciSlotInformation(). - Implement NdisBufferLength(). - Work around my first confirmed NDIS driver bug. The SMC 9462 gigE driver (natsemi 83820-based copper) incorrectly creates a spinlock in its DriverEntry() routine and then destroys it in its MiniportHalt() handler. This is wrong: spinlocks should be created in MiniportInit(). In a Windows environment, this is often not a problem because DriverEntry()/MiniportInit() are called once when the system boots and MiniportHalt() or the shutdown handler is called when the system halts. With this stuff in place, this driver now seems to work: ndis0: <SMC EZ Card 1000> port 0xe000-0xe0ff mem 0xda000000-0xda000fff irq 10 at device 9.0 on pci0 ndis0: assign PCI resources... ndis_open_file("FLASH9.hex", 18446744073709551615) ndis0: Ethernet address: 00:04:e2:0e:d3:f0

Make NdisReadPcmciaAttributeMemory() and NdisWritePcmciaAttributeMemory() actually work. Make the PCI and PCCARD attachments provide a bus_get_resource_list() method so that resource listing for PCCARD works. PCCARD does not have a bus_get_resource_list() method (yet), so I faked up the resource list management in if_ndis_pccard.c, and added bus_get_resource_list() methods to both if_ndis_pccard.c and if_ndis_pci.c. The one in the PCI attechment just hands off to the PCI bus code. The difference is transparent to the NDIS resource handler code. Fixed ndis_open_file() so that opening files which live on NFS filesystems work: pass an actual ucred structure to VOP_GETATTR() (NFS explodes if the ucred structure is NOCRED). Make NdisMMapIoSpace() handle mapping of PCMCIA attribute memory resources correctly. Turn subr_ndis.c:my_strcasecmp() into ndis_strcasecmp() and export it so that if_ndis_pccard.c can use it, and junk the other copy of my_strcasecmp() from if_ndis_pccard.c.

Correct the behavior of ndis_adjust_buflen(): the NDIS spec says it's an error to set the buffer bytecount to anything larger than the buffer's original allocation size, but anything less than that is ok. Also, in ndis_ptom(), use the same logic: if the bytecount is larger than the allocation size, consider the bytecount invalid and the allocation size as the packet fragment length (m_len) instead of the bytecount. This corrects a consistency problem between the Broadcom wireless driver and some of the ethernet drivers I've tested: the ethernet drivers all report the packet frag sizes in buf->nb_bytecount, but the Broadcom wireless driver reports them in buf->nb_size. This seems like a bug to me, but it clearly must work in Windows, so we have to deal with it here too.

Correct the behavior of ndis_adjust_buflen(): the NDIS spec says it's an error to set the buffer bytecount to anything larger than the buffer's original allocation size, but anything less than that is ok. Also, in ndis_ptom(), use the same logic: if the bytecount is larger than the allocation size, consider the bytecount invalid and the allocation size as the packet fragment length (m_len) instead of the bytecount. This corrects a consistency problem between the Broadcom wireless driver and some of the ethernet drivers I've tested: the ethernet drivers all report the packet frag sizes in buf->nb_bytecount, but the Broadcom wireless driver reports them in buf->nb_size. This seems like a bug to me, but it clearly must work in Windows, so we have to deal with it here too.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Make NdisReadPcmciaAttributeMemory() and NdisWritePcmciaAttributeMemory() actually work. Make the PCI and PCCARD attachments provide a bus_get_resource_list() method so that resource listing for PCCARD works. PCCARD does not have a bus_get_resource_list() method (yet), so I faked up the resource list management in if_ndis_pccard.c, and added bus_get_resource_list() methods to both if_ndis_pccard.c and if_ndis_pci.c. The one in the PCI attechment just hands off to the PCI bus code. The difference is transparent to the NDIS resource handler code. Fixed ndis_open_file() so that opening files which live on NFS filesystems work: pass an actual ucred structure to VOP_GETATTR() (NFS explodes if the ucred structure is NOCRED). Make NdisMMapIoSpace() handle mapping of PCMCIA attribute memory resources correctly. Turn subr_ndis.c:my_strcasecmp() into ndis_strcasecmp() and export it so that if_ndis_pccard.c can use it, and junk the other copy of my_strcasecmp() from if_ndis_pccard.c.

Continue my efforts to imitate Windows as closely as possible by attempting to duplicate Windows spinlocks. Windows spinlocks differ from FreeBSD spinlocks in the way they block preemption. FreeBSD spinlocks use critical_enter(), which masks off _all_ interrupts. This prevents any other threads from being scheduled, but it also prevents ISRs from running. In Windows, preemption is achieved by raising the processor IRQL to DISPATCH_LEVEL, which prevents other threads from preempting you, but does _not_ prevent device ISRs from running. (This is essentially what Solaris calls dispatcher locks.) The Windows spinlock itself (kspin_lock) is just an integer value which is atomically set when you acquire the lock and atomically cleared when you release it. FreeBSD doesn't have IRQ levels, so we have to cheat a little by using thread priorities: normal thread priority is PASSIVE_LEVEL, lowest interrupt thread priority is DISPATCH_LEVEL, highest thread priority is DEVICE_LEVEL (PI_REALTIME) and critical_enter() is HIGH_LEVEL. In practice, only PASSIVE_LEVEL and DISPATCH_LEVEL matter to us. The immediate benefit of all this is that I no longer have to rely on a mutex pool. Now, I'm sure many people will be seized by the urge to criticize me for doing an end run around our own spinlock implementation, but it makes more sense to do it this way. Well, it does to me anyway. Overview of the changes: - Properly implement hal_lock(), hal_unlock(), hal_irql(), hal_raise_irql() and hal_lower_irql() so that they more closely resemble their Windows counterparts. The IRQL is determined by thread priority. - Make ntoskrnl_lock_dpc() and ntoskrnl_unlock_dpc() do what they do in Windows, which is to atomically set/clear the lock value. These routines are designed to be called from DISPATCH_LEVEL, and are actually half of the work involved in acquiring/releasing spinlocks. - Add FASTCALL1(), FASTCALL2() and FASTCALL3() macros/wrappers that allow us to call a _fastcall function in spite of the fact that our version of gcc doesn't support __attribute__((__fastcall__)) yet. The macros take 1, 2 or 3 arguments, respectively. We need to call hal_lock(), hal_unlock() etc... ourselves, but can't really invoke the function directly. I could have just made the underlying functions native routines and put _fastcall wrappers around them for the benefit of Windows binaries, but that would create needless bloat. - Remove ndis_mtxpool and all references to it. We don't need it anymore. - Re-implement the NdisSpinLock routines so that they use hal_lock() and friends like they do in Windows. - Use the new spinlock methods for handling lookaside lists and linked list updates in place of the mutex locks that were there before. - Remove mutex locking from ndis_isr() and ndis_intrhand() since they're already called with ndis_intrmtx held in if_ndis.c. - Put ndis_destroy_lock() code under explicit #ifdef notdef/#endif. It turns out there are some drivers which stupidly free the memory in which their spinlocks reside before calling ndis_destroy_lock() on them (touch-after-free bug). The ADMtek wireless driver is guilty of this faux pas. (Why this doesn't clobber Windows I have no idea.) - Make NdisDprAcquireSpinLock() and NdisDprReleaseSpinLock() into real functions instead of aliasing them to NdisAcaquireSpinLock() and NdisReleaseSpinLock(). The Dpr routines use KeAcquireSpinLockAtDpcLevel() level and KeReleaseSpinLockFromDpcLevel(), which acquires the lock without twiddling the IRQL. - In ndis_linksts_done(), do _not_ call ndis_80211_getstate(). Some drivers may call the status/status done callbacks as the result of setting an OID: ndis_80211_getstate() gets OIDs, which means we might cause the driver to recursively access some of its internal structures unexpectedly. The ndis_ticktask() routine will call ndis_80211_getstate() for us eventually anyway. - Fix the channel setting code a little in ndis_80211_setstate(), and initialize the channel to IEEE80211_CHAN_ANYC. (The Microsoft spec says you're not supposed to twiddle the channel in BSS mode; I may need to enforce this later.) This fixes the problems I was having with the ADMtek adm8211 driver: we were setting the channel to a non-standard default, which would cause it to fail to associate in BSS mode. - Use hal_raise_irql() to raise our IRQL to DISPATCH_LEVEL when calling certain miniport routines, per the Microsoft documentation. I think that's everything. Hopefully, other than fixing the ADMtek driver, there should be no apparent change in behavior.

(This is essentially what Solaris calls dispatcher locks.) The Windows spinlock itself (kspin_lock) is just an integer value which is atomically set when you acquire the lock and atomically cleared when you release it. FreeBSD doesn't have IRQ levels, so we have to cheat a little by using thread priorities: normal thread priority is PASSIVE_LEVEL, lowest interrupt thread priority is DISPATCH_LEVEL, highest thread priority is DEVICE_LEVEL (PI_REALTIME) and critical_enter() is HIGH_LEVEL.

Now, I'm sure many people will be seized by the urge to criticize me for doing an end run around our own spinlock implementation, but it makes more sense to do it this way.

Overview of the changes: - Properly implement hal_lock(), hal_unlock(), hal_irql(), hal_raise_irql() and hal_lower_irql() so that they more closely resemble their Windows counterparts.

The ADMtek wireless driver is guilty of this faux pas. (Why this doesn't clobber Windows I have no idea.) - Make NdisDprAcquireSpinLock() and NdisDprReleaseSpinLock() into real functions instead of aliasing them to NdisAcaquireSpinLock() and NdisReleaseSpinLock().

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

More minor cleanups and one small bug fix: - In ntoskrnl_var.h, I had defined compat macros for ntoskrnl_acquire_spinlock() and ntoskrnl_release_spinlock() but never used them. This is fortunate since they were stale. Fix them to work properly. (In Windows/x86 KeAcquireSpinLock() is a macro that calls KefAcquireSpinLock(), which lives in HAL.dll. To imitate this, ntoskrnl_acquire_spinlock() is just a macro that calls hal_lock(), which lives in subr_hal.o.) - Add macros for ntoskrnl_raise_irql() and ntoskrnl_lower_irql() that call hal_raise_irql() and hal_lower_irql(). - Use these macros in kern_ndis.c, subr_ndis.c and subr_ntoskrnl.c. - Along the way, I realised subr_ndis.c:ndis_lock() was not calling hal_lock() correctly (it was using the FASTCALL2() wrapper when in reality this routine is FASTCALL1()). Using the ntoskrnl_acquire_spinlock() fixes this. Not sure if this actually caused any bugs since hal_lock() would have just ignored what was in %edx, but it was still bogus. This hides many of the uses of the FASTCALLx() macros which makes the code a little cleaner. Should not have any effect on generated object code, other than the one fix in ndis_lock().

Continue my efforts to imitate Windows as closely as possible by attempting to duplicate Windows spinlocks. Windows spinlocks differ from FreeBSD spinlocks in the way they block preemption. FreeBSD spinlocks use critical_enter(), which masks off _all_ interrupts. This prevents any other threads from being scheduled, but it also prevents ISRs from running. In Windows, preemption is achieved by raising the processor IRQL to DISPATCH_LEVEL, which prevents other threads from preempting you, but does _not_ prevent device ISRs from running. (This is essentially what Solaris calls dispatcher locks.) The Windows spinlock itself (kspin_lock) is just an integer value which is atomically set when you acquire the lock and atomically cleared when you release it. FreeBSD doesn't have IRQ levels, so we have to cheat a little by using thread priorities: normal thread priority is PASSIVE_LEVEL, lowest interrupt thread priority is DISPATCH_LEVEL, highest thread priority is DEVICE_LEVEL (PI_REALTIME) and critical_enter() is HIGH_LEVEL. In practice, only PASSIVE_LEVEL and DISPATCH_LEVEL matter to us. The immediate benefit of all this is that I no longer have to rely on a mutex pool. Now, I'm sure many people will be seized by the urge to criticize me for doing an end run around our own spinlock implementation, but it makes more sense to do it this way. Well, it does to me anyway. Overview of the changes: - Properly implement hal_lock(), hal_unlock(), hal_irql(), hal_raise_irql() and hal_lower_irql() so that they more closely resemble their Windows counterparts. The IRQL is determined by thread priority. - Make ntoskrnl_lock_dpc() and ntoskrnl_unlock_dpc() do what they do in Windows, which is to atomically set/clear the lock value. These routines are designed to be called from DISPATCH_LEVEL, and are actually half of the work involved in acquiring/releasing spinlocks. - Add FASTCALL1(), FASTCALL2() and FASTCALL3() macros/wrappers that allow us to call a _fastcall function in spite of the fact that our version of gcc doesn't support __attribute__((__fastcall__)) yet. The macros take 1, 2 or 3 arguments, respectively. We need to call hal_lock(), hal_unlock() etc... ourselves, but can't really invoke the function directly. I could have just made the underlying functions native routines and put _fastcall wrappers around them for the benefit of Windows binaries, but that would create needless bloat. - Remove ndis_mtxpool and all references to it. We don't need it anymore. - Re-implement the NdisSpinLock routines so that they use hal_lock() and friends like they do in Windows. - Use the new spinlock methods for handling lookaside lists and linked list updates in place of the mutex locks that were there before. - Remove mutex locking from ndis_isr() and ndis_intrhand() since they're already called with ndis_intrmtx held in if_ndis.c. - Put ndis_destroy_lock() code under explicit #ifdef notdef/#endif. It turns out there are some drivers which stupidly free the memory in which their spinlocks reside before calling ndis_destroy_lock() on them (touch-after-free bug). The ADMtek wireless driver is guilty of this faux pas. (Why this doesn't clobber Windows I have no idea.) - Make NdisDprAcquireSpinLock() and NdisDprReleaseSpinLock() into real functions instead of aliasing them to NdisAcaquireSpinLock() and NdisReleaseSpinLock(). The Dpr routines use KeAcquireSpinLockAtDpcLevel() level and KeReleaseSpinLockFromDpcLevel(), which acquires the lock without twiddling the IRQL. - In ndis_linksts_done(), do _not_ call ndis_80211_getstate(). Some drivers may call the status/status done callbacks as the result of setting an OID: ndis_80211_getstate() gets OIDs, which means we might cause the driver to recursively access some of its internal structures unexpectedly. The ndis_ticktask() routine will call ndis_80211_getstate() for us eventually anyway. - Fix the channel setting code a little in ndis_80211_setstate(), and initialize the channel to IEEE80211_CHAN_ANYC. (The Microsoft spec says you're not supposed to twiddle the channel in BSS mode; I may need to enforce this later.) This fixes the problems I was having with the ADMtek adm8211 driver: we were setting the channel to a non-standard default, which would cause it to fail to associate in BSS mode. - Use hal_raise_irql() to raise our IRQL to DISPATCH_LEVEL when calling certain miniport routines, per the Microsoft documentation. I think that's everything. Hopefully, other than fixing the ADMtek driver, there should be no apparent change in behavior.

It appears drivers may call NdisWriteErrorLogEntry() with locks held. However, if we need to translate a unicode message table message, ndis_unicode_to_ascii() might malloc() some memory, which causes a warning from witness. Avoid this by using some stack space to hold the translated message. (Also bounds check to make sure we don't overrun the stack buffer.)

Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Avoid this by using some stack space to hold the translated message. (Also bounds check to make sure we don't overrun the stack buffer.)

Make NdisReadPcmciaAttributeMemory() and NdisWritePcmciaAttributeMemory() actually work. Make the PCI and PCCARD attachments provide a bus_get_resource_list() method so that resource listing for PCCARD works. PCCARD does not have a bus_get_resource_list() method (yet), so I faked up the resource list management in if_ndis_pccard.c, and added bus_get_resource_list() methods to both if_ndis_pccard.c and if_ndis_pci.c. The one in the PCI attechment just hands off to the PCI bus code. The difference is transparent to the NDIS resource handler code. Fixed ndis_open_file() so that opening files which live on NFS filesystems work: pass an actual ucred structure to VOP_GETATTR() (NFS explodes if the ucred structure is NOCRED). Make NdisMMapIoSpace() handle mapping of PCMCIA attribute memory resources correctly. Turn subr_ndis.c:my_strcasecmp() into ndis_strcasecmp() and export it so that if_ndis_pccard.c can use it, and junk the other copy of my_strcasecmp() from if_ndis_pccard.c.

- Add pe_get_message() and pe_get_messagetable() for processing the RT_MESSAGETABLE resources that some driver binaries have. This allows us to print error messages in ndis_syslog(). - Correct the implementation of InterlockedIncrement() and InterlockedDecrement() -- they return uint32_t, not void. - Correct the declarations of the 64-bit arithmetic shift routines in subr_ntoskrnl.c (_allshr, allshl, etc...). These do not follow the _stdcall convention: instead, they appear to be __attribute__((regparm(3)). - Change the implementation of KeInitializeSpinLock(). There is no complementary KeFreeSpinLock() function, so creating a new mutex on each call to KeInitializeSpinLock() leaks resources when a driver is unloaded. For now, KeInitializeSpinLock() returns a handle to the ntoskrnl interlock mutex. - Use a driver's MiniportDisableInterrupt() and MiniportEnableInterrupt() routines if they exist. I'm not sure if I'm doing this right yet, but at the very least this shouldn't break any currently working drivers, and it makes the Intel PRO/1000 driver work. - In ndis_register_intr(), save some state that might be needed later, and save a pointer to the driver's interrupt structure in the ndis_miniport_block. - Save a pointer to the driver image for use by ndis_syslog() when it calls pe_get_message().

Re-do the handling of ndis_buffers. The NDIS_BUFFER structure is supposed to be opaque to the driver, however it is exposed through several macros which expect certain behavior. In my original implementation, I used the mappedsystemva member of the structure to hold a pointer to the buffer and bytecount to hold the length. It turns out you must use the startva pointer to point to the page containing the start of the buffer and set byteoffset to the offset within the page where the buffer starts. So, for a buffer with address 'baseva,' startva is baseva & ~(PAGE_SIZE -1) and byteoffset is baseva & (PAGE_SIZE -1). We have to maintain this convention everywhere that ndis_buffers are used. Fortunately, Microsoft defines some macros for initializing and manipulating NDIS_BUFFER structures in ntddk.h. I adapted some of them for use here and used them where appropriate. This fixes the discrepancy I observed between how RX'ed packet sizes were being reported in the Broadcom wireless driver and the sample ethernet drivers that I've tested. This should also help the Intel Centrino wireless driver work. Also try to properly initialize the 802.11 BSS and IBSS channels. (Sadly, the channel value is meaningless since there's no way in the existing NDIS API to get/set the channel, but this should take care of any 'invalid channel (NULL)' messages printed on the console.

To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Reorganize the timer code a little and implement NdisInitializeTimer() and NdisCancelTimer(). NdisInitializeTimer() doesn't accept an NDIS miniport context argument, so we have to derive it from the timer function context (which is supposed to be the adapter private context). NdisCancelTimer is now an alias for NdisMCancelTimer(). Also add stubs for NdisMRegisterDevice() and NdisMDeregisterDevice(). These are no-ops for now, but will likely get fleshed in once I start working on the Am1771/Am1772 wireless driver.

This reduces code duplication and more closely imitates the way things are done in Windows. - Modify ndis_encode_parm() to deal with the case where we have a registry key expressed as a hex value ("0x1") which is being read via NdisReadConfiguration() as an int. Previously, we tried to decode things like "0x1" with strtol() using a base of 10, which would always yield 0. This is what was causing problems with the Intel 2200BG Centrino 802.11g driver: the .inf file that comes with it has a key called RadioEnable with a value of 0x1. We incorrectly decoded this value to '0' when it was queried, hence the driver thought we wanted the radio turned off. - In if_ndis.c, most drivers don't accept NDIS_80211_AUTHMODE_AUTO, but NDIS_80211_AUTHMODE_SHARED may not be right in some cases, so for now always use NDIS_80211_AUTHMODE_OPEN. NOTE: There is still one problem with the Intel 2200BG driver: it happens that the kernel stack in Windows is larger than the kernel stack in FreeBSD. The 2200BG driver sometimes eats up more than 2 pages of stack space, which can lead to a double fault panic. For the moment, I got things to work by adding the following to my kernel config file: options KSTACK_PAGES=8 I'm pretty sure 8 is too big; I just picked this value out of a hat as a test, and it happened to work, so I left it. 4 pages might be enough. Unfortunately, I don't think you can dynamically give a thread a larger stack, so I'm not sure how to handle this short of putting a note in the man page about it and dealing with the flood of mail from people who never read man pages.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys).

It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes.

((int64_t)msecs * -10000), &timer->nt_kdpc);
Fix several issues related to the KeInitializeTimer() etc... API stuff that I added recently: - When a periodic timer fires, it's automatically re-armed. We must make sure to re-arm the timer _before_ invoking any caller-supplied defered procedure call: the DPC may choose to call KeCancelTimer(), and re-arming the timer after the DPC un-does the effect of the cancel. - Fix similar issue with periodic timers in subr_ndis.c. - When calling KeSetTimer() or KeSetTimerEx(), if the timer is already pending, untimeout() it first before timeout()ing it again. - The old Atheros driver for the 5211 seems to use KeSetTimerEx() incorrectly, or at the very least in a very strange way that doesn't quite follow the Microsoft documentation. In one case, it calls KeSetTimerEx() with a duetime of 0 and a period of 5000. The Microsoft documentation says that negative duetime values are relative to the current time and positive values are absolute. But it doesn't say what's supposed to happen with positive values that less than the current time, i.e. absolute values that are in the past. Lacking any further information, I have decided that timers with positive duetimes that are in the past should fire right away (or in our case, after only 1 tick). This also takes care of the other strange usage in the Atheros driver, where the duetime is specified as 500000 and the period is 50. I think someone may have meant to use -500000 and misinterpreted the documentation. - Also modified KeWaitForSingleObject() and KeWaitForMultipleObjects() to make the same duetime adjustment, since they have the same rules regarding timeout values. - Cosmetic: change name of 'timeout' variable in KeWaitForSingleObject() and KeWaitForMultipleObjects() to 'duetime' to avoid senseless (though harmless) overlap with timeout() function name. With these fixes, I can get the 5211 card to associate properly with my adhoc net using driver AR5211.SYS version 2.4.1.6.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

- Rewrite the timer and event API routines in subr_ndis.c so that they are actually layered on top of the KeTimer API in subr_ntoskrnl.c, just as it is in Windows. This reduces code duplication and more closely imitates the way things are done in Windows. - Modify ndis_encode_parm() to deal with the case where we have a registry key expressed as a hex value ("0x1") which is being read via NdisReadConfiguration() as an int. Previously, we tried to decode things like "0x1" with strtol() using a base of 10, which would always yield 0. This is what was causing problems with the Intel 2200BG Centrino 802.11g driver: the .inf file that comes with it has a key called RadioEnable with a value of 0x1. We incorrectly decoded this value to '0' when it was queried, hence the driver thought we wanted the radio turned off. - In if_ndis.c, most drivers don't accept NDIS_80211_AUTHMODE_AUTO, but NDIS_80211_AUTHMODE_SHARED may not be right in some cases, so for now always use NDIS_80211_AUTHMODE_OPEN. NOTE: There is still one problem with the Intel 2200BG driver: it happens that the kernel stack in Windows is larger than the kernel stack in FreeBSD. The 2200BG driver sometimes eats up more than 2 pages of stack space, which can lead to a double fault panic. For the moment, I got things to work by adding the following to my kernel config file: options KSTACK_PAGES=8 I'm pretty sure 8 is too big; I just picked this value out of a hat as a test, and it happened to work, so I left it. 4 pages might be enough.

Technically, this isn't supposed to work since, although Microsoft added the extended rate structure with the NDIS 5.1 update, the spec still says that the OID_802_11_SUPPORTED_RATES OID uses ndis_80211_rates. In spite of this, it appears some drivers use it anyway. - When adding in our guessed rates, check to see if they already exist so that we avoid any duplicates. - Add a printf() to ndis_open_file() that alerts the user when a driver attempts to open a file under /compat/ndis. With these changes, I can get the driver for the SMC 2802W 54g PCI card to load and run. This board uses a Prism54G chip. Note that in order for this driver to work, you must place the supplied smc2802w.arm firmware image under /compat/ndis. (The firmware is not resident on the device.) Note that this should also allow the 3Com 3CRWE154G72 card to work as well; as far as I can tell, these cards also use a Prism54G chip.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Loosen up the range test in ndis_register_ioport(). Allow drivers to map ranges that are smaller than what our resource manager code knows is available, rather than requiring that they match exactly. This fixes a problem with the Intel PRO/1000 gigE driver: it wants to map a range of 32 I/O ports, even though some chips appear set up to decode a range of 64. With this fix, it loads and runs correctly.

Fix two problems: - In subr_ndis.c:ndis_allocate_sharemem(), create the busdma tags used for shared memory allocations with a lowaddr of 0x3E7FFFFF. This forces the buffers to be mapped to physical/bus addresses within the first 1GB of physical memory. It seems that at least one card (Linksys Instant Wireless PCI V2.7) depends on this behavior. I don't know if this is a hardware restriction, or if the NDIS driver for this card is truncating the addresses itself, but using physical/bus addresses beyong the 1GB limit causes initialization failures. - Create am NDIS_INITIALIZED() macro in if_ndisvar.h and use it in if_ndis.c to test whether the device has been initialized rather than checking for the presence of the IFF_UP flag in if_flags. While debugging the previous problem, I noticed that bringing up the device would always produce failures from ndis_setmulti(). It turns out that the following steps now occur during device initialization: - IFF_UP flag is set in if_flags - ifp->if_ioctl() called with SIOCSIFADDR (which we don't handle) - ifp->if_ioctl() called with SIOCADDMULTI - ifp->if_ioctl() called with SIOCADDMULTI (again) - ifp->if_ioctl() called with SIOCADDMULTI (yet again) - ifp->if_ioctl() called with SIOCSIFFLAGS Setting the receive filter and multicast filters can only be done when the underlying NDIS driver has been initialized, which is done by ifp->if_init(). However, we don't call ifp->if_init() until ifp->if_ioctl() is called with SIOCSIFFLAGS and IFF_UP has been set. It appears that now, the network stack tries to add multicast addresses to interface's filter before those steps occur. Normally, ndis_setmulti() would trap this condition by checking for the IFF_UP flag, but the network code has in fact set this flag already, so ndis_setmulti() is fooled into thinking the interface has been initialized when it really hasn't. It turns out this is usually harmless because the ifp->if_init() routine (in this case ndis_init()) will set up the multicast filter when it initializes the hardware anyway, and the underlying routines (ndis_get_info()/ndis_set_info()) know that the driver/NIC haven't been initialized yet, but you end up spurious error messages on the console all the time. Something tells me this new behavior isn't really correct. I think the intention was to fix it so that ifp->if_init() is only called once when we ifconfig an interface up, but the end result seems a little bogus: the change of the IFF_UP flag should be propagated down to the driver before calling any other ioctl() that might actually require the hardware to be up and running.

I think the intention was to fix it so that ifp->if_init() is only called once when we ifconfig an interface up, but the end result seems a little bogus: the change of the IFF_UP flag should be propagated down to the driver before calling any other ioctl() that might actually require the hardware to be up and running.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Correct/improve the implementation of NdisMAllocateSharedMemoryAsync(). Since we have a worker thread now, we can actually do the allocation asynchronously in that thread's context. Also, we need to return a status value: if we're unable to queue up the async allocation, we return NDIS_STATUS_FAILURE, otherwise we return NDIS_STATUS_PENDING to indicate the allocation has been queued and will occur later. This replaces the kludge where we just invoked the callback routine right away in the current context.

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

Correct/improve the implementation of NdisMAllocateSharedMemoryAsync(). Since we have a worker thread now, we can actually do the allocation asynchronously in that thread's context. Also, we need to return a status value: if we're unable to queue up the async allocation, we return NDIS_STATUS_FAILURE, otherwise we return NDIS_STATUS_PENDING to indicate the allocation has been queued and will occur later. This replaces the kludge where we just invoked the callback routine right away in the current context.

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o.

PCCARD does not have a bus_get_resource_list() method (yet), so I faked up the resource list management in if_ndis_pccard.c, and added bus_get_resource_list() methods to both if_ndis_pccard.c and if_ndis_pci.c. The one in the PCI attechment just hands off to the PCI bus code. The difference is transparent to the NDIS resource handler code. Fixed ndis_open_file() so that opening files which live on NFS filesystems work: pass an actual ucred structure to VOP_GETATTR() (NFS explodes if the ucred structure is NOCRED). Make NdisMMapIoSpace() handle mapping of PCMCIA attribute memory resources correctly. Turn subr_ndis.c:my_strcasecmp() into ndis_strcasecmp() and export it so that if_ndis_pccard.c can use it, and junk the other copy of my_strcasecmp() from if_ndis_pccard.c.

Add sanity checks to the ndis_packet and ndis_buffer pool handling routines to guard against problems caused by (possibly) buggy drivers. The RealTek 8180 wireless driver calls NdisFreeBuffer() to release some of its buffers _after_ it's already called NdisFreeBufferPool() to destroy the pool to which the buffers belong. In our implementation, this error causes NdisFreeBuffer() to touch stale heap memory. If you are running a release kernel, and hence have INVARIANTS et al turned off, it turns out nothing happens. But if you're using a development kernel config with INVARIANTS on, the malloc()/free() sanity checks will scribble over the pool memory with 0xdeadc0de once it's released so that any attempts to touch it will cause a trap, and indeed this is what happens. It happens that I run 5.2-RELEASE on my laptop, so when I tested the rtl8180.sys driver, it worked fine for me, but people trying to run it with development systems checked out or cvsupped from -current would get a page fault on driver load. I can't find any reason why the NDISulator would cause the RealTek driver to do the NdisFreeBufferPool() prematurely, and the same driver obviously works with Windows -- or at least, it doesn't cause a crash: the Microsoft documentation for NdisFreeBufferPool() says that failing to return all buffers to the pool before calling NdisFreeBufferPool() causes a memory leak.

In ndis_attach(), report the NDIS API level that the Windows miniport driver was compiled with. Remove debug printf from ndis_assicn_pcirsc(). It doesn't serve much purpose. Implement NdisMIndicateStatus() and NdisMIndicateStatusComplete() as functions in subr_ndis.c. In NDIS 4.0, they were functions. In NDIS 5.0 and later, they're just macros. Allocate a few extra packets/buffers beyond what the driver asks for since sometimes it seems they can lie about how many they really need, and some extra stupid ones don't check to see if NdisAllocatePacket() and/or NdisAllocateBuffer() actually succeed.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

The private data section of ndis_packets has a 'packet flags' byte which has two important flags in it: the 'allocated by NDIS' flag and the 'media specific info present' flag. There are two Windows macros for getting/setting media specific info fields within the ndis_packet structure which can behave improperly if these flags are not initialized correctly when a packet is allocated. It seems the correct thing to do is always set the NDIS_PACKET_ALLOCATED_BY_NDIS flag on all newly allocated packets. This fixes the crashes with the Intel Centrino wireless driver. My sample card now seems to work correctly. Also, fix a potential LOR involving ndis_txeof() in if_ndis.c.

There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Now that I finally have power back, implement a couple more NDIS API routines: NdisUnchainBufferAtBack(), NdisGetFirstBufferFromPacketSafe() and NdisGetFirstBufferFromPacket(). This should bring us a little closer to getting the Intel centrino wireless NIC to work. Note: I have not actually tested these additions since I don't have a driver that calls them, however they're pretty simple, and one of them is taken pretty much directly from the Windows ndis.h header file, so I'm fairly confident they work, but disclaimers apply.

Add sanity checks to the ndis_packet and ndis_buffer pool handling routines to guard against problems caused by (possibly) buggy drivers. The RealTek 8180 wireless driver calls NdisFreeBuffer() to release some of its buffers _after_ it's already called NdisFreeBufferPool() to destroy the pool to which the buffers belong. In our implementation, this error causes NdisFreeBuffer() to touch stale heap memory. If you are running a release kernel, and hence have INVARIANTS et al turned off, it turns out nothing happens. But if you're using a development kernel config with INVARIANTS on, the malloc()/free() sanity checks will scribble over the pool memory with 0xdeadc0de once it's released so that any attempts to touch it will cause a trap, and indeed this is what happens. It happens that I run 5.2-RELEASE on my laptop, so when I tested the rtl8180.sys driver, it worked fine for me, but people trying to run it with development systems checked out or cvsupped from -current would get a page fault on driver load. I can't find any reason why the NDISulator would cause the RealTek driver to do the NdisFreeBufferPool() prematurely, and the same driver obviously works with Windows -- or at least, it doesn't cause a crash: the Microsoft documentation for NdisFreeBufferPool() says that failing to return all buffers to the pool before calling NdisFreeBufferPool() causes a memory leak. I've written to my contacts at RealTek asking them to check if this is indeed a bug in their driver. In the meantime, these new sanity checks will catch this problem and issue a warning rather than causing a trap. The trick is to keep a count of outstanding buffers for each buffer pool, and if the driver tries to call NdisFreeBufferPool() while there are still buffers outstanding, we mark the pool for deletion and then defer destroying it until after the last buffer has been reclaimed.

Add sanity checks to the ndis_packet and ndis_buffer pool handling routines to guard against problems caused by (possibly) buggy drivers. The RealTek 8180 wireless driver calls NdisFreeBuffer() to release some of its buffers _after_ it's already called NdisFreeBufferPool() to destroy the pool to which the buffers belong. In our implementation, this error causes NdisFreeBuffer() to touch stale heap memory. If you are running a release kernel, and hence have INVARIANTS et al turned off, it turns out nothing happens. But if you're using a development kernel config with INVARIANTS on, the malloc()/free() sanity checks will scribble over the pool memory with 0xdeadc0de once it's released so that any attempts to touch it will cause a trap, and indeed this is what happens. It happens that I run 5.2-RELEASE on my laptop, so when I tested the rtl8180.sys driver, it worked fine for me, but people trying to run it with development systems checked out or cvsupped from -current would get a page fault on driver load. I can't find any reason why the NDISulator would cause the RealTek driver to do the NdisFreeBufferPool() prematurely, and the same driver obviously works with Windows -- or at least, it doesn't cause a crash: the Microsoft documentation for NdisFreeBufferPool() says that failing to return all buffers to the pool before calling NdisFreeBufferPool() causes a memory leak. I've written to my contacts at RealTek asking them to check if this is indeed a bug in their driver. In the meantime, these new sanity checks will catch this problem and issue a warning rather than causing a trap. The trick is to keep a count of outstanding buffers for each buffer pool, and if the driver tries to call NdisFreeBufferPool() while there are still buffers outstanding, we mark the pool for deletion and then defer destroying it until after the last buffer has been reclaimed.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes.

Re-do the handling of ndis_buffers. The NDIS_BUFFER structure is supposed to be opaque to the driver, however it is exposed through several macros which expect certain behavior. In my original implementation, I used the mappedsystemva member of the structure to hold a pointer to the buffer and bytecount to hold the length. It turns out you must use the startva pointer to point to the page containing the start of the buffer and set byteoffset to the offset within the page where the buffer starts. So, for a buffer with address 'baseva,' startva is baseva & ~(PAGE_SIZE -1) and byteoffset is baseva & (PAGE_SIZE -1). We have to maintain this convention everywhere that ndis_buffers are used. Fortunately, Microsoft defines some macros for initializing and manipulating NDIS_BUFFER structures in ntddk.h. I adapted some of them for use here and used them where appropriate. This fixes the discrepancy I observed between how RX'ed packet sizes were being reported in the Broadcom wireless driver and the sample ethernet drivers that I've tested. This should also help the Intel Centrino wireless driver work. Also try to properly initialize the 802.11 BSS and IBSS channels. (Sadly, the channel value is meaningless since there's no way in the existing NDIS API to get/set the channel, but this should take care of any 'invalid channel (NULL)' messages printed on the console.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Re-do the handling of ndis_buffers. The NDIS_BUFFER structure is supposed to be opaque to the driver, however it is exposed through several macros which expect certain behavior. In my original implementation, I used the mappedsystemva member of the structure to hold a pointer to the buffer and bytecount to hold the length. It turns out you must use the startva pointer to point to the page containing the start of the buffer and set byteoffset to the offset within the page where the buffer starts. So, for a buffer with address 'baseva,' startva is baseva & ~(PAGE_SIZE -1) and byteoffset is baseva & (PAGE_SIZE -1). We have to maintain this convention everywhere that ndis_buffers are used. Fortunately, Microsoft defines some macros for initializing and manipulating NDIS_BUFFER structures in ntddk.h. I adapted some of them for use here and used them where appropriate. This fixes the discrepancy I observed between how RX'ed packet sizes were being reported in the Broadcom wireless driver and the sample ethernet drivers that I've tested. This should also help the Intel Centrino wireless driver work. Also try to properly initialize the 802.11 BSS and IBSS channels. (Sadly, the channel value is meaningless since there's no way in the existing NDIS API to get/set the channel, but this should take care of any 'invalid channel (NULL)' messages printed on the console.

- Rewrite the timer and event API routines in subr_ndis.c so that they are actually layered on top of the KeTimer API in subr_ntoskrnl.c, just as it is in Windows. This reduces code duplication and more closely imitates the way things are done in Windows. - Modify ndis_encode_parm() to deal with the case where we have a registry key expressed as a hex value ("0x1") which is being read via NdisReadConfiguration() as an int. Previously, we tried to decode things like "0x1" with strtol() using a base of 10, which would always yield 0. This is what was causing problems with the Intel 2200BG Centrino 802.11g driver: the .inf file that comes with it has a key called RadioEnable with a value of 0x1. We incorrectly decoded this value to '0' when it was queried, hence the driver thought we wanted the radio turned off. - In if_ndis.c, most drivers don't accept NDIS_80211_AUTHMODE_AUTO, but NDIS_80211_AUTHMODE_SHARED may not be right in some cases, so for now always use NDIS_80211_AUTHMODE_OPEN. NOTE: There is still one problem with the Intel 2200BG driver: it happens that the kernel stack in Windows is larger than the kernel stack in FreeBSD. The 2200BG driver sometimes eats up more than 2 pages of stack space, which can lead to a double fault panic. For the moment, I got things to work by adding the following to my kernel config file: options KSTACK_PAGES=8 I'm pretty sure 8 is too big; I just picked this value out of a hat as a test, and it happened to work, so I left it. 4 pages might be enough. Unfortunately, I don't think you can dynamically give a thread a larger stack, so I'm not sure how to handle this short of putting a note in the man page about it and dealing with the flood of mail from people who never read man pages.

- In subr_ndis.c:ndis_init_event(), initialize events as notification objects rather than synchronization objects. When a sync object is signaled, only the first thread waiting on it is woken up, and then it's automatically reset to the not-signaled state. When a notification object is signaled, all threads waiting on it will be woken up, and it remains in the signaled state until someone resets it manually. We want the latter behavior for NDIS events. - In kern_ndis.c:ndis_convert_res(), we have to create a temporary copy of the list returned by BUS_GET_RESOURCE_LIST(). When the PCI bus code probes resources for a given device, it enters them into a singly linked list, head first. The result is that traversing this list gives you the resources in reverse order. This means when we create the Windows resource list, it will be in reverse order too. Unfortunately, this can hose drivers for devices with multiple I/O ranges of the same type, like, say, two memory mapped I/O regions (one for registers, one to map the NVRAM/bootrom/whatever). Some drivers test the range size to figure out which region is which, but others just assume that the resources will be listed in ascending order from lowest numbered BAR to highest. Reversing the order means such drivers will choose the wrong resource as their I/O register range. Since we can't traverse the resource SLIST backwards, we have to make a temporary copy of the list in the right order and then build the Windows resource list from that. I suppose we could just fix the PCI bus code to use a TAILQ instead, but then I'd have to track down all the consumers of the BUS_GET_RESOURCE_LIST() and fix them too.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

- Rewrite the timer and event API routines in subr_ndis.c so that they are actually layered on top of the KeTimer API in subr_ntoskrnl.c, just as it is in Windows. This reduces code duplication and more closely imitates the way things are done in Windows. - Modify ndis_encode_parm() to deal with the case where we have a registry key expressed as a hex value ("0x1") which is being read via NdisReadConfiguration() as an int. Previously, we tried to decode things like "0x1" with strtol() using a base of 10, which would always yield 0. This is what was causing problems with the Intel 2200BG Centrino 802.11g driver: the .inf file that comes with it has a key called RadioEnable with a value of 0x1. We incorrectly decoded this value to '0' when it was queried, hence the driver thought we wanted the radio turned off. - In if_ndis.c, most drivers don't accept NDIS_80211_AUTHMODE_AUTO, but NDIS_80211_AUTHMODE_SHARED may not be right in some cases, so for now always use NDIS_80211_AUTHMODE_OPEN. NOTE: There is still one problem with the Intel 2200BG driver: it happens that the kernel stack in Windows is larger than the kernel stack in FreeBSD. The 2200BG driver sometimes eats up more than 2 pages of stack space, which can lead to a double fault panic. For the moment, I got things to work by adding the following to my kernel config file: options KSTACK_PAGES=8 I'm pretty sure 8 is too big; I just picked this value out of a hat as a test, and it happened to work, so I left it. 4 pages might be enough. Unfortunately, I don't think you can dynamically give a thread a larger stack, so I'm not sure how to handle this short of putting a note in the man page about it and dealing with the flood of mail from people who never read man pages.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Re-do the handling of ndis_buffers. The NDIS_BUFFER structure is supposed to be opaque to the driver, however it is exposed through several macros which expect certain behavior. In my original implementation, I used the mappedsystemva member of the structure to hold a pointer to the buffer and bytecount to hold the length. It turns out you must use the startva pointer to point to the page containing the start of the buffer and set byteoffset to the offset within the page where the buffer starts. So, for a buffer with address 'baseva,' startva is baseva & ~(PAGE_SIZE -1) and byteoffset is baseva & (PAGE_SIZE -1). We have to maintain this convention everywhere that ndis_buffers are used. Fortunately, Microsoft defines some macros for initializing and manipulating NDIS_BUFFER structures in ntddk.h. I adapted some of them for use here and used them where appropriate. This fixes the discrepancy I observed between how RX'ed packet sizes were being reported in the Broadcom wireless driver and the sample ethernet drivers that I've tested. This should also help the Intel Centrino wireless driver work. Also try to properly initialize the 802.11 BSS and IBSS channels. (Sadly, the channel value is meaningless since there's no way in the existing NDIS API to get/set the channel, but this should take care of any 'invalid channel (NULL)' messages printed on the console.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

In if_ndis.c:ndis_attach(), temporarily set the IFF_UP flag while calling the haltfunc. If an interrupt is triggered by the init or halt func, the IFF_UP flag must be set in order for us to be able to service it. In kern_ndis.c: implement a handler for NdisMSendResourcesAvailable() (currently does nothing since we don't really need it).

The SMC 9462 gigE driver (natsemi 83820-based copper) incorrectly creates a spinlock in its DriverEntry() routine and then destroys it in its MiniportHalt() handler. This is wrong: spinlocks should be created in MiniportInit(). In a Windows environment, this is often not a problem because DriverEntry()/MiniportInit() are called once when the system boots and MiniportHalt() or the shutdown handler is called when the system halts. With this stuff in place, this driver now seems to work: ndis0: <SMC EZ Card 1000> port 0xe000-0xe0ff mem 0xda000000-0xda000fff irq 10 at device 9.0 on pci0 ndis0: assign PCI resources... ndis_open_file("FLASH9.hex", 18446744073709551615) ndis0: Ethernet address: 00:04:e2:0e:d3:f0

Make NdisReadPcmciaAttributeMemory() and NdisWritePcmciaAttributeMemory() actually work. Make the PCI and PCCARD attachments provide a bus_get_resource_list() method so that resource listing for PCCARD works. PCCARD does not have a bus_get_resource_list() method (yet), so I faked up the resource list management in if_ndis_pccard.c, and added bus_get_resource_list() methods to both if_ndis_pccard.c and if_ndis_pci.c. The one in the PCI attechment just hands off to the PCI bus code. The difference is transparent to the NDIS resource handler code. Fixed ndis_open_file() so that opening files which live on NFS filesystems work: pass an actual ucred structure to VOP_GETATTR() (NFS explodes if the ucred structure is NOCRED). Make NdisMMapIoSpace() handle mapping of PCMCIA attribute memory resources correctly. Turn subr_ndis.c:my_strcasecmp() into ndis_strcasecmp() and export it so that if_ndis_pccard.c can use it, and junk the other copy of my_strcasecmp() from if_ndis_pccard.c.

Make NdisReadPcmciaAttributeMemory() and NdisWritePcmciaAttributeMemory() actually work. Make the PCI and PCCARD attachments provide a bus_get_resource_list() method so that resource listing for PCCARD works. PCCARD does not have a bus_get_resource_list() method (yet), so I faked up the resource list management in if_ndis_pccard.c, and added bus_get_resource_list() methods to both if_ndis_pccard.c and if_ndis_pci.c. The one in the PCI attechment just hands off to the PCI bus code. The difference is transparent to the NDIS resource handler code. Fixed ndis_open_file() so that opening files which live on NFS filesystems work: pass an actual ucred structure to VOP_GETATTR() (NFS explodes if the ucred structure is NOCRED). Make NdisMMapIoSpace() handle mapping of PCMCIA attribute memory resources correctly. Turn subr_ndis.c:my_strcasecmp() into ndis_strcasecmp() and export it so that if_ndis_pccard.c can use it, and junk the other copy of my_strcasecmp() from if_ndis_pccard.c.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

Using the ntoskrnl_acquire_spinlock() fixes this. Not sure if this actually caused any bugs since hal_lock() would have just ignored what was in %edx, but it was still bogus. This hides many of the uses of the FASTCALLx() macros which makes the code a little cleaner. Should not have any effect on generated object code, other than the one fix in ndis_lock().

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o.

More minor cleanups and one small bug fix: - In ntoskrnl_var.h, I had defined compat macros for ntoskrnl_acquire_spinlock() and ntoskrnl_release_spinlock() but never used them. This is fortunate since they were stale. Fix them to work properly. (In Windows/x86 KeAcquireSpinLock() is a macro that calls KefAcquireSpinLock(), which lives in HAL.dll. To imitate this, ntoskrnl_acquire_spinlock() is just a macro that calls hal_lock(), which lives in subr_hal.o.) - Add macros for ntoskrnl_raise_irql() and ntoskrnl_lower_irql() that call hal_raise_irql() and hal_lower_irql(). - Use these macros in kern_ndis.c, subr_ndis.c and subr_ntoskrnl.c. - Along the way, I realised subr_ndis.c:ndis_lock() was not calling hal_lock() correctly (it was using the FASTCALL2() wrapper when in reality this routine is FASTCALL1()). Using the ntoskrnl_acquire_spinlock() fixes this. Not sure if this actually caused any bugs since hal_lock() would have just ignored what was in %edx, but it was still bogus. This hides many of the uses of the FASTCALLx() macros which makes the code a little cleaner. Should not have any effect on generated object code, other than the one fix in ndis_lock().

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use).

More minor cleanups and one small bug fix: - In ntoskrnl_var.h, I had defined compat macros for ntoskrnl_acquire_spinlock() and ntoskrnl_release_spinlock() but never used them. This is fortunate since they were stale. Fix them to work properly. (In Windows/x86 KeAcquireSpinLock() is a macro that calls KefAcquireSpinLock(), which lives in HAL.dll. To imitate this, ntoskrnl_acquire_spinlock() is just a macro that calls hal_lock(), which lives in subr_hal.o.) - Add macros for ntoskrnl_raise_irql() and ntoskrnl_lower_irql() that call hal_raise_irql() and hal_lower_irql(). - Use these macros in kern_ndis.c, subr_ndis.c and subr_ntoskrnl.c. - Along the way, I realised subr_ndis.c:ndis_lock() was not calling hal_lock() correctly (it was using the FASTCALL2() wrapper when in reality this routine is FASTCALL1()). Using the ntoskrnl_acquire_spinlock() fixes this. Not sure if this actually caused any bugs since hal_lock() would have just ignored what was in %edx, but it was still bogus. This hides many of the uses of the FASTCALLx() macros which makes the code a little cleaner. Should not have any effect on generated object code, other than the one fix in ndis_lock().

Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress.

Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Modify if_ndis.c so that the MiniportISR function runs in ndis_intr() and MiniportHandleInterrupt() is fired off later via a task queue in ndis_intrtask(). This more accurately follows the NDIS interrupt handling model, where the ISR does a minimal amount of work in interrupt context and the handler is defered and run at a lower priority. Create a separate ndis_intrmtx mutex just for the guarding the ISR. Modify NdisSynchronizeWithInterrupt() to aquire the ndis_intrmtx mutex before invoking the synchronized procedure. (The purpose of this function is to provide mutual exclusion for code that shares variables with the ISR.) Modify NdisMRegisterInterrupt() to save a pointer to the miniport block in the ndis_miniport_interrupt structure so that NdisSynchronizeWithInterrupt() can grab it later and derive ndis_intrmtx from it.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader.

Continue my efforts to imitate Windows as closely as possible by attempting to duplicate Windows spinlocks. Windows spinlocks differ from FreeBSD spinlocks in the way they block preemption. FreeBSD spinlocks use critical_enter(), which masks off _all_ interrupts. This prevents any other threads from being scheduled, but it also prevents ISRs from running. In Windows, preemption is achieved by raising the processor IRQL to DISPATCH_LEVEL, which prevents other threads from preempting you, but does _not_ prevent device ISRs from running. (This is essentially what Solaris calls dispatcher locks.) The Windows spinlock itself (kspin_lock) is just an integer value which is atomically set when you acquire the lock and atomically cleared when you release it. FreeBSD doesn't have IRQ levels, so we have to cheat a little by using thread priorities: normal thread priority is PASSIVE_LEVEL, lowest interrupt thread priority is DISPATCH_LEVEL, highest thread priority is DEVICE_LEVEL (PI_REALTIME) and critical_enter() is HIGH_LEVEL. In practice, only PASSIVE_LEVEL and DISPATCH_LEVEL matter to us. The immediate benefit of all this is that I no longer have to rely on a mutex pool. Now, I'm sure many people will be seized by the urge to criticize me for doing an end run around our own spinlock implementation, but it makes more sense to do it this way. Well, it does to me anyway. Overview of the changes: - Properly implement hal_lock(), hal_unlock(), hal_irql(), hal_raise_irql() and hal_lower_irql() so that they more closely resemble their Windows counterparts. The IRQL is determined by thread priority. - Make ntoskrnl_lock_dpc() and ntoskrnl_unlock_dpc() do what they do in Windows, which is to atomically set/clear the lock value. These routines are designed to be called from DISPATCH_LEVEL, and are actually half of the work involved in acquiring/releasing spinlocks. - Add FASTCALL1(), FASTCALL2() and FASTCALL3() macros/wrappers that allow us to call a _fastcall function in spite of the fact that our version of gcc doesn't support __attribute__((__fastcall__)) yet. The macros take 1, 2 or 3 arguments, respectively. We need to call hal_lock(), hal_unlock() etc... ourselves, but can't really invoke the function directly. I could have just made the underlying functions native routines and put _fastcall wrappers around them for the benefit of Windows binaries, but that would create needless bloat. - Remove ndis_mtxpool and all references to it. We don't need it anymore. - Re-implement the NdisSpinLock routines so that they use hal_lock() and friends like they do in Windows. - Use the new spinlock methods for handling lookaside lists and linked list updates in place of the mutex locks that were there before. - Remove mutex locking from ndis_isr() and ndis_intrhand() since they're already called with ndis_intrmtx held in if_ndis.c. - Put ndis_destroy_lock() code under explicit #ifdef notdef/#endif. It turns out there are some drivers which stupidly free the memory in which their spinlocks reside before calling ndis_destroy_lock() on them (touch-after-free bug). The ADMtek wireless driver is guilty of this faux pas. (Why this doesn't clobber Windows I have no idea.) - Make NdisDprAcquireSpinLock() and NdisDprReleaseSpinLock() into real functions instead of aliasing them to NdisAcaquireSpinLock() and NdisReleaseSpinLock(). The Dpr routines use KeAcquireSpinLockAtDpcLevel() level and KeReleaseSpinLockFromDpcLevel(), which acquires the lock without twiddling the IRQL. - In ndis_linksts_done(), do _not_ call ndis_80211_getstate(). Some drivers may call the status/status done callbacks as the result of setting an OID: ndis_80211_getstate() gets OIDs, which means we might cause the driver to recursively access some of its internal structures unexpectedly. The ndis_ticktask() routine will call ndis_80211_getstate() for us eventually anyway. - Fix the channel setting code a little in ndis_80211_setstate(), and initialize the channel to IEEE80211_CHAN_ANYC. (The Microsoft spec says you're not supposed to twiddle the channel in BSS mode; I may need to enforce this later.) This fixes the problems I was having with the ADMtek adm8211 driver: we were setting the channel to a non-standard default, which would cause it to fail to associate in BSS mode. - Use hal_raise_irql() to raise our IRQL to DISPATCH_LEVEL when calling certain miniport routines, per the Microsoft documentation. I think that's everything. Hopefully, other than fixing the ADMtek driver, there should be no apparent change in behavior.

Implement some more NDIS and ntoskrnl API calls: subr_ndis.c: NdisGetCurrentSystemTime() which, according to the Microsoft documentation returns "the number of 100 nanosecond intervals since January 1, 1601." I have no idea what's so special about that epoch or why they chose 100 nanosecond ticks. I don't know the proper offset to convert nanotime() from the UNIX epoch to January 1, 1601, so for now I'm just doing the unit convertion to 100s of nanoseconds. subr_ntoskrnl.c: memcpy(), memset(), ExInterlockedPopEntrySList(), ExInterlockedPushEntrySList(). The latter two are different from InterlockedPopEntrySList() and InterlockedPushEntrySList() in that they accept a spinlock to hold while executing, whereas the non-Ex routines use a lock internal to ntoskrnl. I also modified ExInitializePagedLookasideList() and ExInitializeNPagedLookasideList() to initialize mutex locks within the lookaside structures. It seems that in NDIS 5.0, the lookaside allocate/free routines ExInterlockedPopEntrySList() and ExInterlockedPushEntrySList(), which require the use of the per-lookaside spinlock, whereas in NDIS 5.1, the per-lookaside spinlock is deprecated. We need to support both cases. Note that I appear to be doing something wrong with ExInterlockedPopEntrySList() and ExInterlockedPushEntrySList(): they don't appear to obtain proper pointers to their arguments, so I'm probably doing something wrong in terms of their calling convention (they're declared to be FASTCALL in Widnows, and I'm not sure what that means for gcc). It happens that in my stub lookaside implementation, they don't need to do any work anyway, so for now I've hacked them to always return NULL, which avoids corrupting the stack. I need to do this right though.

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

It seems that in NDIS 5.0, the lookaside allocate/free routines ExInterlockedPopEntrySList() and ExInterlockedPushEntrySList(), which require the use of the per-lookaside spinlock, whereas in NDIS 5.1, the per-lookaside spinlock is deprecated. We need to support both cases. Note that I appear to be doing something wrong with ExInterlockedPopEntrySList() and ExInterlockedPushEntrySList(): they don't appear to obtain proper pointers to their arguments, so I'm probably doing something wrong in terms of their calling convention (they're declared to be FASTCALL in Widnows, and I'm not sure what that means for gcc). It happens that in my stub lookaside implementation, they don't need to do any work anyway, so for now I've hacked them to always return NULL, which avoids corrupting the stack. I need to do this right though.

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

Re-do the handling of ndis_buffers. The NDIS_BUFFER structure is supposed to be opaque to the driver, however it is exposed through several macros which expect certain behavior. In my original implementation, I used the mappedsystemva member of the structure to hold a pointer to the buffer and bytecount to hold the length. It turns out you must use the startva pointer to point to the page containing the start of the buffer and set byteoffset to the offset within the page where the buffer starts. So, for a buffer with address 'baseva,' startva is baseva & ~(PAGE_SIZE -1) and byteoffset is baseva & (PAGE_SIZE -1). We have to maintain this convention everywhere that ndis_buffers are used. Fortunately, Microsoft defines some macros for initializing and manipulating NDIS_BUFFER structures in ntddk.h. I adapted some of them for use here and used them where appropriate. This fixes the discrepancy I observed between how RX'ed packet sizes were being reported in the Broadcom wireless driver and the sample ethernet drivers that I've tested. This should also help the Intel Centrino wireless driver work. Also try to properly initialize the 802.11 BSS and IBSS channels. (Sadly, the channel value is meaningless since there's no way in the existing NDIS API to get/set the channel, but this should take care of any 'invalid channel (NULL)' messages printed on the console.

Big mess 'o changes: - Give ndiscvt(8) the ability to process a .SYS file directly into a .o file so that we don't have to emit big messy char arrays into the ndis_driver_data.h file. This behavior is currently optional, but may become the default some day. - Give ndiscvt(8) the ability to turn arbitrary files into .ko files so that they can be pre-loaded or kldloaded. (Both this and the previous change involve using objcopy(1)). - Give NdisOpenFile() the ability to 'read' files out of kernel memory that have been kldloaded or pre-loaded, and disallow the use of the normal vn_open() file opening method during bootstrap (when no filesystems have been mounted yet). Some people have reported that kldloading if_ndis.ko works fine when the system is running multiuser but causes a panic when the modile is pre-loaded by /boot/loader. This happens with drivers that need to use NdisOpenFile() to access external files (i.e. firmware images). NdisOpenFile() won't work during kernel bootstrapping because no filesystems have been mounted. To get around this, you can now do the following: o Say you have a firmware file called firmware.img o Do: ndiscvt -f firmware.img -- this creates firmware.img.ko o Put the firmware.img.ko in /boot/kernel o add firmware.img_load="YES" in /boot/loader.conf o add if_ndis_load="YES" and ndis_load="YES" as well Now the loader will suck the additional file into memory as a .ko. The phony .ko has two symbols in it: filename_start and filename_end, which are generated by objcopy(1). ndis_open_file() will traverse each module in the module list looking for these symbols and, if it finds them, it'll use them to generate the file mapping address and length values that the caller of NdisOpenFile() wants. As a bonus, this will even work if the file has been statically linked into the kernel itself, since the "kernel" module is searched too. (ndiscvt(8) will generate both filename.o and filename.ko for you). - Modify the mechanism used to provide make-pretend FASTCALL support. Rather than using inline assembly to yank the first two arguments out of %ecx and %edx, we now use the __regparm__(3) attribute (and the __stdcall__ attribute) and use some macro magic to re-order the arguments and provide dummy arguments as needed so that the arguments passed in registers end up in the right place.

Make the Texas Instruments 802.11g chipset work with the NDISulator. This was tested with a Netgear WG311v2 802.11b/g PCI card. Things that were fixed: - This chip has two memory mapped regions, one at PCIR_BAR(0) and the other at PCIR_BAR(1). This is a little different from the other chips I've seen with two PCI shared memory regions, since they tend to have the second BAR ad PCIR_BAR(2). if_ndis_pci.c tests explicitly for PCIR_BAR(2). This has been changed to simply fill in ndis_res_mem first and ndis_res_altmem second, if a second shared memory range exists. Given that NDIS drivers seem to scan for BARs in ascending order, I think this should be ok. - Fixed the code that tries to process firmware images that have been loaded as .ko files. To save a step, I was setting up the address mapping in ndis_open_file(), but ndis_map_file() flags pre-existing mappings as an error (to avoid duplicate mappings). Changed this so that the mapping is now donw in ndis_map_file() as expected. - Made the typedef for 'driver_entry' explicitly include __stdcall to silence gcc warning in ndis_load_driver(). NOTE: the Texas Instruments ACX111 driver needs firmware. With my card, there were 3 .bin files shipped with the driver. You must either put these files in /compat/ndis or convert them with ndiscvt -f and kldload them so the driver can use them. Without the firmware image, the NIC won't work.

This is a little different from the other chips I've seen with two PCI shared memory regions, since they tend to have the second BAR ad PCIR_BAR(2). if_ndis_pci.c tests explicitly for PCIR_BAR(2). This has been changed to simply fill in ndis_res_mem first and ndis_res_altmem second, if a second shared memory range exists. Given that NDIS drivers seem to scan for BARs in ascending order, I think this should be ok. - Fixed the code that tries to process firmware images that have been loaded as .ko files. To save a step, I was setting up the address mapping in ndis_open_file(), but ndis_map_file() flags pre-existing mappings as an error (to avoid duplicate mappings). Changed this so that the mapping is now donw in ndis_map_file() as expected. - Made the typedef for 'driver_entry' explicitly include __stdcall to silence gcc warning in ndis_load_driver(). NOTE: the Texas Instruments ACX111 driver needs firmware. With my card, there were 3 .bin files shipped with the driver. You must either put these files in /compat/ndis or convert them with ndiscvt -f and kldload them so the driver can use them. Without the firmware image, the NIC won't work.

Big mess 'o changes: - Give ndiscvt(8) the ability to process a .SYS file directly into a .o file so that we don't have to emit big messy char arrays into the ndis_driver_data.h file.

Some people have reported that kldloading if_ndis.ko works fine when the system is running multiuser but causes a panic when the modile is pre-loaded by /boot/loader. This happens with drivers that need to use NdisOpenFile() to access external files (i.e. firmware images). NdisOpenFile() won't work during kernel bootstrapping because no filesystems have been mounted. To get around this, you can now do the following: o Say you have a firmware file called firmware.img o Do: ndiscvt -f firmware.img -- this creates firmware.img.ko o Put the firmware.img.ko in /boot/kernel o add firmware.img_load="YES" in /boot/loader.conf o add if_ndis_load="YES" and ndis_load="YES" as well Now the loader will suck the additional file into memory as a .ko. The phony .ko has two symbols in it: filename_start and filename_end, which are generated by objcopy(1). ndis_open_file() will traverse each module in the module list looking for these symbols and, if it finds them, it'll use them to generate the file mapping address and length values that the caller of NdisOpenFile() wants. As a bonus, this will even work if the file has been statically linked into the kernel itself, since the "kernel" module is searched too. (ndiscvt(8) will generate both filename.o and filename.ko for you). - Modify the mechanism used to provide make-pretend FASTCALL support. Rather than using inline assembly to yank the first two arguments out of %ecx and %edx, we now use the __regparm__(3) attribute (and the __stdcall__ attribute) and use some macro magic to re-order the arguments and provide dummy arguments as needed so that the arguments passed in registers end up in the right place.

Implement support for single packet sends. The Intel Centrino driver that Asus provides on its CDs has both a MiniportSend() routine and a MiniportSendPackets() function. The Microsoft NDIS docs say that if a driver has both, only the MiniportSendPackets() routine will be used. Although I think I implemented the support correctly, calling the MiniportSend() routine seems to result in no packets going out on the air, even though no error status is returned. The MiniportSendPackets() function does work though, so at least in this case it doesn't matter. In if_ndis.c:ndis_getstate_80211(), if ndis_get_assoc() returns an error, don't bother trying to obtain any other state since the calls may fail, or worse cause the underlying driver to crash. (The above two changes make the Asus-supplied Centrino work.) Also, when calling the OID_802_11_CONFIGURATION OID, remember to initialize the structure lengths correctly. In subr_ndis.c:ndis_open_file(), set the current working directory to rootvnode if we're in a thread that doesn't have a current working directory set.

- The MiniportReset() function can return NDIS_STATUS_PENDING, in which case we should wait for the resetdone handler to be called before returning. - When providing resources via ndis_query_resources(), uses the computed rsclen when using bcopy() to copy out the resource data rather than the caller-supplied buffer length. - Avoid using ndis_reset_nic() in if_ndis.c unless we really need to reset the NIC because of a problem. - Allow interrupts to be fielded during ndis_attach(), at least as far as allowing ndis_isr() and ndis_intrhand() to run. - Use ndis_80211_rates_ex when probing for supported rates. Technically, this isn't supposed to work since, although Microsoft added the extended rate structure with the NDIS 5.1 update, the spec still says that the OID_802_11_SUPPORTED_RATES OID uses ndis_80211_rates. In spite of this, it appears some drivers use it anyway. - When adding in our guessed rates, check to see if they already exist so that we avoid any duplicates. - Add a printf() to ndis_open_file() that alerts the user when a driver attempts to open a file under /compat/ndis. With these changes, I can get the driver for the SMC 2802W 54g PCI card to load and run. This board uses a Prism54G chip. Note that in order for this driver to work, you must place the supplied smc2802w.arm firmware image under /compat/ndis. (The firmware is not resident on the device.) Note that this should also allow the 3Com 3CRWE154G72 card to work as well; as far as I can tell, these cards also use a Prism54G chip.

NOTE: the Texas Instruments ACX111 driver needs firmware. With my card, there were 3 .bin files shipped with the driver. You must either put these files in /compat/ndis or convert them with ndiscvt -f and kldload them so the driver can use them. Without the firmware image, the NIC won't work.

Big mess 'o changes: - Give ndiscvt(8) the ability to process a .SYS file directly into a .o file so that we don't have to emit big messy char arrays into the ndis_driver_data.h file. This behavior is currently optional, but may become the default some day. - Give ndiscvt(8) the ability to turn arbitrary files into .ko files so that they can be pre-loaded or kldloaded. (Both this and the previous change involve using objcopy(1)). - Give NdisOpenFile() the ability to 'read' files out of kernel memory that have been kldloaded or pre-loaded, and disallow the use of the normal vn_open() file opening method during bootstrap (when no filesystems have been mounted yet). Some people have reported that kldloading if_ndis.ko works fine when the system is running multiuser but causes a panic when the modile is pre-loaded by /boot/loader. This happens with drivers that need to use NdisOpenFile() to access external files (i.e. firmware images). NdisOpenFile() won't work during kernel bootstrapping because no filesystems have been mounted. To get around this, you can now do the following: o Say you have a firmware file called firmware.img o Do: ndiscvt -f firmware.img -- this creates firmware.img.ko o Put the firmware.img.ko in /boot/kernel o add firmware.img_load="YES" in /boot/loader.conf o add if_ndis_load="YES" and ndis_load="YES" as well Now the loader will suck the additional file into memory as a .ko. The phony .ko has two symbols in it: filename_start and filename_end, which are generated by objcopy(1). ndis_open_file() will traverse each module in the module list looking for these symbols and, if it finds them, it'll use them to generate the file mapping address and length values that the caller of NdisOpenFile() wants. As a bonus, this will even work if the file has been statically linked into the kernel itself, since the "kernel" module is searched too. (ndiscvt(8) will generate both filename.o and filename.ko for you). - Modify the mechanism used to provide make-pretend FASTCALL support. Rather than using inline assembly to yank the first two arguments out of %ecx and %edx, we now use the __regparm__(3) attribute (and the __stdcall__ attribute) and use some macro magic to re-order the arguments and provide dummy arguments as needed so that the arguments passed in registers end up in the right place.

Make the Texas Instruments 802.11g chipset work with the NDISulator. This was tested with a Netgear WG311v2 802.11b/g PCI card. Things that were fixed: - This chip has two memory mapped regions, one at PCIR_BAR(0) and the other at PCIR_BAR(1). This is a little different from the other chips I've seen with two PCI shared memory regions, since they tend to have the second BAR ad PCIR_BAR(2). if_ndis_pci.c tests explicitly for PCIR_BAR(2). This has been changed to simply fill in ndis_res_mem first and ndis_res_altmem second, if a second shared memory range exists. Given that NDIS drivers seem to scan for BARs in ascending order, I think this should be ok. - Fixed the code that tries to process firmware images that have been loaded as .ko files. To save a step, I was setting up the address mapping in ndis_open_file(), but ndis_map_file() flags pre-existing mappings as an error (to avoid duplicate mappings).

Implement NdisMIndicateStatus() and NdisMIndicateStatusComplete() as functions in subr_ndis.c. In NDIS 4.0, they were functions. In NDIS 5.0 and later, they're just macros. Allocate a few extra packets/buffers beyond what the driver asks for since sometimes it seems they can lie about how many they really need, and some extra stupid ones don't check to see if NdisAllocatePacket() and/or NdisAllocateBuffer() actually succeed.

Reorganize the timer code a little and implement NdisInitializeTimer() and NdisCancelTimer(). NdisInitializeTimer() doesn't accept an NDIS miniport context argument, so we have to derive it from the timer function context (which is supposed to be the adapter private context). NdisCancelTimer is now an alias for NdisMCancelTimer(). Also add stubs for NdisMRegisterDevice() and NdisMDeregisterDevice(). These are no-ops for now, but will likely get fleshed in once I start working on the Am1771/Am1772 wireless driver.

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

Allocate a few extra packets/buffers beyond what the driver asks for since sometimes it seems they can lie about how many they really need, and some extra stupid ones don't check to see if NdisAllocatePacket() and/or NdisAllocateBuffer() actually succeed.

Note: I have not actually tested these additions since I don't have a driver that calls them, however they're pretty simple, and one of them is taken pretty much directly from the Windows ndis.h header file, so I'm fairly confident they work, but disclaimers apply.

subr_ndis.c: - fix ndis_time() so that it returns a time based on the proper epoch (wacky though it may be) - implement NdisInitializeString() and NdisFreeString(), and add stub for NdisMRemoveMiniport() ntoskrnl_var.h: - add missing member to the general_lookaside struct (gl_listentry) subr_ntoskrnl.c: - Fix arguments to the interlocked push/pop routines: 'head' is an slist_header *, not an slist_entry * - Kludge up _fastcall support for the push/pop routines. The _fastcall convention is similar to _stdcall, except the first two available DWORD-sized arguments are passed in %ecx and %edx, respectively. One kludge for this __attribute__ ((regparm(3))), however this isn't entirely right, as it assumes %eax, %ecx and %edx will be used (regparm(2) assumes %eax and %edx). Another kludge is to declare the two fastcall-ed args as local register variables and explicitly assign them to %ecx and %edx, but experimentation showed that gcc would not guard %ecx and %edx against being clobbered. Thus, I came up with a 3rd kludge, which is to use some inline assembly of the form: void *arg1; void *arg2; __asm__("movl %%ecx, %%ecx" : "=c" (arg1)); __asm__("movl %%edx, %%edx" : "=d" (arg2)); This lets gcc know that we're going to reference %ecx and %edx and that it should make an effort not to let it get trampled. This wastes an instruction (movl %reg, %reg is a no-op) but insures proper behavior. It's possible there's a better way to do this though: this is the first time I've used inline assembler in this fashion. The above fixes to ntoskrnl_var.h an subr_ntoskrnl.c make lookaside lists work for the two drivers I have that use them, one of which is an NDIS 5.0 miniport and another which is 5.1.

Implement some more NDIS and ntoskrnl API calls: subr_ndis.c: NdisGetCurrentSystemTime() which, according to the Microsoft documentation returns "the number of 100 nanosecond intervals since January 1, 1601." I have no idea what's so special about that epoch or why they chose 100 nanosecond ticks. I don't know the proper offset to convert nanotime() from the UNIX epoch to January 1, 1601, so for now I'm just doing the unit convertion to 100s of nanoseconds. subr_ntoskrnl.c: memcpy(), memset(), ExInterlockedPopEntrySList(), ExInterlockedPushEntrySList(). The latter two are different from InterlockedPopEntrySList() and InterlockedPushEntrySList() in that they accept a spinlock to hold while executing, whereas the non-Ex routines use a lock internal to ntoskrnl. I also modified ExInitializePagedLookasideList() and ExInitializeNPagedLookasideList() to initialize mutex locks within the lookaside structures. It seems that in NDIS 5.0, the lookaside allocate/free routines ExInterlockedPopEntrySList() and ExInterlockedPushEntrySList(), which require the use of the per-lookaside spinlock, whereas in NDIS 5.1, the per-lookaside spinlock is deprecated. We need to support both cases. Note that I appear to be doing something wrong with ExInterlockedPopEntrySList() and ExInterlockedPushEntrySList(): they don't appear to obtain proper pointers to their arguments, so I'm probably doing something wrong in terms of their calling convention (they're declared to be FASTCALL in Widnows, and I'm not sure what that means for gcc). It happens that in my stub lookaside implementation, they don't need to do any work anyway, so for now I've hacked them to always return NULL, which avoids corrupting the stack. I need to do this right though.

Continue my efforts to imitate Windows as closely as possible by attempting to duplicate Windows spinlocks. Windows spinlocks differ from FreeBSD spinlocks in the way they block preemption. FreeBSD spinlocks use critical_enter(), which masks off _all_ interrupts. This prevents any other threads from being scheduled, but it also prevents ISRs from running. In Windows, preemption is achieved by raising the processor IRQL to DISPATCH_LEVEL, which prevents other threads from preempting you, but does _not_ prevent device ISRs from running. (This is essentially what Solaris calls dispatcher locks.) The Windows spinlock itself (kspin_lock) is just an integer value which is atomically set when you acquire the lock and atomically cleared when you release it. FreeBSD doesn't have IRQ levels, so we have to cheat a little by using thread priorities: normal thread priority is PASSIVE_LEVEL, lowest interrupt thread priority is DISPATCH_LEVEL, highest thread priority is DEVICE_LEVEL (PI_REALTIME) and critical_enter() is HIGH_LEVEL. In practice, only PASSIVE_LEVEL and DISPATCH_LEVEL matter to us. The immediate benefit of all this is that I no longer have to rely on a mutex pool. Now, I'm sure many people will be seized by the urge to criticize me for doing an end run around our own spinlock implementation, but it makes more sense to do it this way. Well, it does to me anyway. Overview of the changes: - Properly implement hal_lock(), hal_unlock(), hal_irql(), hal_raise_irql() and hal_lower_irql() so that they more closely resemble their Windows counterparts. The IRQL is determined by thread priority. - Make ntoskrnl_lock_dpc() and ntoskrnl_unlock_dpc() do what they do in Windows, which is to atomically set/clear the lock value. These routines are designed to be called from DISPATCH_LEVEL, and are actually half of the work involved in acquiring/releasing spinlocks. - Add FASTCALL1(), FASTCALL2() and FASTCALL3() macros/wrappers that allow us to call a _fastcall function in spite of the fact that our version of gcc doesn't support __attribute__((__fastcall__)) yet. The macros take 1, 2 or 3 arguments, respectively. We need to call hal_lock(), hal_unlock() etc... ourselves, but can't really invoke the function directly. I could have just made the underlying functions native routines and put _fastcall wrappers around them for the benefit of Windows binaries, but that would create needless bloat. - Remove ndis_mtxpool and all references to it. We don't need it anymore. - Re-implement the NdisSpinLock routines so that they use hal_lock() and friends like they do in Windows. - Use the new spinlock methods for handling lookaside lists and linked list updates in place of the mutex locks that were there before. - Remove mutex locking from ndis_isr() and ndis_intrhand() since they're already called with ndis_intrmtx held in if_ndis.c. - Put ndis_destroy_lock() code under explicit #ifdef notdef/#endif. It turns out there are some drivers which stupidly free the memory in which their spinlocks reside before calling ndis_destroy_lock() on them (touch-after-free bug). The ADMtek wireless driver is guilty of this faux pas. (Why this doesn't clobber Windows I have no idea.) - Make NdisDprAcquireSpinLock() and NdisDprReleaseSpinLock() into real functions instead of aliasing them to NdisAcaquireSpinLock() and NdisReleaseSpinLock(). The Dpr routines use KeAcquireSpinLockAtDpcLevel() level and KeReleaseSpinLockFromDpcLevel(), which acquires the lock without twiddling the IRQL. - In ndis_linksts_done(), do _not_ call ndis_80211_getstate(). Some drivers may call the status/status done callbacks as the result of setting an OID: ndis_80211_getstate() gets OIDs, which means we might cause the driver to recursively access some of its internal structures unexpectedly. The ndis_ticktask() routine will call ndis_80211_getstate() for us eventually anyway. - Fix the channel setting code a little in ndis_80211_setstate(), and initialize the channel to IEEE80211_CHAN_ANYC. (The Microsoft spec says you're not supposed to twiddle the channel in BSS mode; I may need to enforce this later.) This fixes the problems I was having with the ADMtek adm8211 driver: we were setting the channel to a non-standard default, which would cause it to fail to associate in BSS mode. - Use hal_raise_irql() to raise our IRQL to DISPATCH_LEVEL when calling certain miniport routines, per the Microsoft documentation. I think that's everything. Hopefully, other than fixing the ADMtek driver, there should be no apparent change in behavior.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys). It still needs to have a net80211 stuff added to it. To use it, you would do something like this: # cd /sys/modules/ndis # make; make load # cd /sys/modules/if_ndis # ndiscvt -i /path/to/foo.inf -s /path/to/foo.sys -o ndis_driver_data.h # make; make load # sysctl -a | grep ndis All registry keys are mapped to sysctl nodes. Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

In if_ndis.c:ndis_attach(), temporarily set the IFF_UP flag while calling the haltfunc. If an interrupt is triggered by the init or halt func, the IFF_UP flag must be set in order for us to be able to service it. In kern_ndis.c: implement a handler for NdisMSendResourcesAvailable() (currently does nothing since we don't really need it). In subr_ndis.c: - Correct ndis_init_string() and ndis_unicode_to_ansi(), which were both horribly broken. - Implement NdisImmediateReadPciSlotInformation() and NdisImmediateWritePciSlotInformation(). - Implement NdisBufferLength(). - Work around my first confirmed NDIS driver bug. The SMC 9462 gigE driver (natsemi 83820-based copper) incorrectly creates a spinlock in its DriverEntry() routine and then destroys it in its MiniportHalt() handler. This is wrong: spinlocks should be created in MiniportInit(). In a Windows environment, this is often not a problem because DriverEntry()/MiniportInit() are called once when the system boots and MiniportHalt() or the shutdown handler is called when the system halts. With this stuff in place, this driver now seems to work: ndis0: <SMC EZ Card 1000> port 0xe000-0xe0ff mem 0xda000000-0xda000fff irq 10 at device 9.0 on pci0 ndis0: assign PCI resources... ndis_open_file("FLASH9.hex", 18446744073709551615) ndis0: Ethernet address: 00:04:e2:0e:d3:f0

Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

These changes allow the Level 1 1000baseSX driver to work for the following card: ndis0: <SMC TigerCard 1000 Adapter> port 0xe000-0xe0ff mem 0xda004000-0xda0043ff irq 10 at device 9.0 on pci0 ndis0: Ethernet address: 00:e0:29:6f:cc:04 This is already supported by the lge(4) driver, but I decided to take a try at making the Windows driver that came with it work too, since I still had the floppy diskette for it lying around.

Commit the first cut of Project Evil, also known as the NDISulator. Yes, it's what you think it is. Yes, you should run away now. This is a special compatibility module for allowing Windows NDIS miniport network drivers to be used with FreeBSD/x86. This provides _binary_ NDIS compatibility (not source): you can run NDIS driver code, but you can't build it. There are three main parts: sys/compat/ndis: the NDIS compat API, which provides binary compatibility functions for many routines in NDIS.SYS, HAL.dll and ntoskrnl.exe in Windows (these are the three modules that most NDIS miniport drivers use). The compat module also contains a small PE relocator/dynalinker which relocates the Windows .SYS image and then patches in our native routines. sys/dev/if_ndis: the if_ndis driver wrapper. This module makes use of the ndis compat API and can be compiled with a specially prepared binary image file (ndis_driver_data.h) containing the Windows .SYS image and registry key information parsed out of the accompanying .INF file. Once if_ndis.ko is built, it can be loaded and unloaded just like a native FreeBSD kenrel module. usr.sbin/ndiscvt: a special utility that converts foo.sys and foo.inf into an ndis_driver_data.h file that can be compiled into if_ndis.o. Contains an .inf file parser graciously provided by Matt Dodd (and mercilessly hacked upon by me) that strips out device ID info and registry key info from a .INF file and packages it up with a binary image array. The ndiscvt(8) utility also does some manipulation of the segments within the .sys file to make life easier for the kernel loader. (Doing the manipulation here saves the kernel code from having to move things around later, which would waste memory.) ndiscvt is only built for the i386 arch. Only files.i386 has been updated, and none of this is turned on in GENERIC. It should probably work on pc98. I have no idea about amd64 or ia64 at this point. This is still a work in progress. I estimate it's about %85 done, but I want it under CVS control so I can track subsequent changes. It has been tested with exactly three drivers: the LinkSys LNE100TX v4 driver (Lne100v4.sys), the sample Intel 82559 driver from the Windows DDK (e100bex.sys) and the Broadcom BCM43xx wireless driver (bcmwl5.sys).

Sometimes drivers refer to registry keys that aren't mentioned in foo.inf. If this happens, the NDIS API module creates sysctl nodes for these keys on the fly so you can tweak them. An example usage of the Broadcom wireless driver would be: # sysctl hw.ndis0.EnableAutoConnect=1 # sysctl hw.ndis0.SSID="MY_SSID" # sysctl hw.ndis0.NetworkType=0 (0 for bss, 1 for adhoc) # ifconfig ndis0 <my ipaddr> netmask 0xffffff00 up Things to be done: - get rid of debug messages - add in ndis80211 support - defer transmissions until after a status update with NDIS_STATUS_CONNECTED occurs - Create smarter lookaside list support - Split off if_ndis_pci.c and if_ndis_pccard.c attachments - Make sure PCMCIA support works - Fix ndiscvt to properly parse PCMCIA device IDs from INF files - write ndisapi.9 man page

In if_ndis.c:ndis_attach(), temporarily set the IFF_UP flag while calling the haltfunc. If an interrupt is triggered by the init or halt func, the IFF_UP flag must be set in order for us to be able to service it. In kern_ndis.c: implement a handler for NdisMSendResourcesAvailable() (currently does nothing since we don't really need it). In subr_ndis.c: - Correct ndis_init_string() and ndis_unicode_to_ansi(), which were both horribly broken. - Implement NdisImmediateReadPciSlotInformation() and NdisImmediateWritePciSlotInformation(). - Implement NdisBufferLength(). - Work around my first confirmed NDIS driver bug. The SMC 9462 gigE driver (natsemi 83820-based copper) incorrectly creates a spinlock in its DriverEntry() routine and then destroys it in its MiniportHalt() handler. This is wrong: spinlocks should be created in MiniportInit(). In a Windows environment, this is often not a problem because DriverEntry()/MiniportInit() are called once when the system boots and MiniportHalt() or the shutdown handler is called when the system halts. With this stuff in place, this driver now seems to work: ndis0: <SMC EZ Card 1000> port 0xe000-0xe0ff mem 0xda000000-0xda000fff irq 10 at device 9.0 on pci0 ndis0: assign PCI resources... ndis_open_file("FLASH9.hex", 18446744073709551615) ndis0: Ethernet address: 00:04:e2:0e:d3:f0

Reorganize the timer code a little and implement NdisInitializeTimer() and NdisCancelTimer(). NdisInitializeTimer() doesn't accept an NDIS miniport context argument, so we have to derive it from the timer function context (which is supposed to be the adapter private context). NdisCancelTimer is now an alias for NdisMCancelTimer(). Also add stubs for NdisMRegisterDevice() and NdisMDeregisterDevice(). These are no-ops for now, but will likely get fleshed in once I start working on the Am1771/Am1772 wireless driver.

Add a whole bunch of new stuff to make the driver for the AMD Am1771/Am1772 802.11b chipset work. This chip is present on the SMC2602W version 3 NIC, which is what was used for testing. This driver creates kernel threads (12 of them!) for various purposes, and required the following routines: PsCreateSystemThread() PsTerminateSystemThread() KeInitializeEvent() KeSetEvent() KeResetEvent() KeInitializeMutex() KeReleaseMutex() KeWaitForSingleObject() KeWaitForMultipleObjects() IoGetDeviceProperty() and several more. Also, this driver abuses the fact that NDIS events and timers are actually Windows events and timers, and uses NDIS events with KeWaitForSingleObject(). The NDIS event routines have been rewritten to interface with the ntoskrnl module. Many routines with incorrect prototypes have been cleaned up. Also, this driver puts jobs on the NDIS taskqueue (via NdisScheduleWorkItem()) which block on events, and this interferes with the operation of NdisMAllocateSharedMemoryAsync(), which was also being put on the NDIS taskqueue. To avoid the deadlock, NdisMAllocateSharedMemoryAsync() is now performed in the NDIS SWI thread instead. There's still room for some cleanups here, and I really should implement KeInitializeTimer() and friends.
