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

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.

Merge in some changes submitted by Brian Feldman. Among other things, these add support for listing BSSIDs via wicontrol -l. I added code to call OID_802_11_BSSID_LIST_SCAN to allow scanning for any nearby wirelsss nets. Convert from using individual mutexes to a mutex pool, created in subr_ndis.c. This deals with the problem of drivers creating locks in their DriverEntry() routines which might get trashed later. Put some messages under IFF_DEBUG.

Deal with the duplicate sysctl leaf problem. A .inf file may contain definitions for more than one device (usually differentiated by the PCI subvendor/subdevice ID). Each device also has its own tree of registry keys. In some cases, each device has the same keys, but sometimes each device has a unique tree but with overlap. Originally, I just had ndiscvt(8) dump out all the keys it could find, and we would try to apply them to every device we could find. Now, each key has an index number that matches it to a device in the device ID list. This lets us create just the keys that apply to a particular device. I also added an extra field to the device list to hold the subvendor and subdevice ID. Some devices are generic, i.e. there is no subsystem definition. If we have a device that doesn't match a specific subsystem value and we have a generic entry, we use the generic entry.

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.

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.

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

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.

Deal with the duplicate sysctl leaf problem. A .inf file may contain definitions for more than one device (usually differentiated by the PCI subvendor/subdevice ID). Each device also has its own tree of registry keys. In some cases, each device has the same keys, but sometimes each device has a unique tree but with overlap. Originally, I just had ndiscvt(8) dump out all the keys it could find, and we would try to apply them to every device we could find. Now, each key has an index number that matches it to a device in the device ID list. This lets us create just the keys that apply to a particular device. I also added an extra field to the device list to hold the subvendor and subdevice ID. Some devices are generic, i.e. there is no subsystem definition. If we have a device that doesn't match a specific subsystem value and we have a generic entry, we use the generic entry.

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.

Deal with the duplicate sysctl leaf problem. A .inf file may contain definitions for more than one device (usually differentiated by the PCI subvendor/subdevice ID). Each device also has its own tree of registry keys. In some cases, each device has the same keys, but sometimes each device has a unique tree but with overlap. Originally, I just had ndiscvt(8) dump out all the keys it could find, and we would try to apply them to every device we could find. Now, each key has an index number that matches it to a device in the device ID list. This lets us create just the keys that apply to a particular device. I also added an extra field to the device list to hold the subvendor and subdevice ID. Some devices are generic, i.e. there is no subsystem definition. If we have a device that doesn't match a specific subsystem value and we have a generic entry, we use the generic entry.

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.

Rework resource allocation. Replace the "feel around like a blind man" method with something a little more intelligent: use BUS_GET_RESOURCE_LIST() to run through all resources allocated to us and map them as needed. This way we know exactly what resources need to be mapped and what their RIDs are without having to guess. This simplifies both ndis_attach() and ndis_convert_res(), and eliminates the unfriendly "ndisX: couldn't map <foo>" messages that are sometimes emitted during driver load.

Originally, I just had ndiscvt(8) dump out all the keys it could find, and we would try to apply them to every device we could find. Now, each key has an index number that matches it to a device in the device ID list. This lets us create just the keys that apply to a particular device. I also added an extra field to the device list to hold the subvendor and subdevice ID. Some devices are generic, i.e. there is no subsystem definition. If we have a device that doesn't match a specific subsystem value and we have a generic entry, we use the generic entry.

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

Rework resource allocation. Replace the "feel around like a blind man" method with something a little more intelligent: use BUS_GET_RESOURCE_LIST() to run through all resources allocated to us and map them as needed. This way we know exactly what resources need to be mapped and what their RIDs are without having to guess. This simplifies both ndis_attach() and ndis_convert_res(), and eliminates the unfriendly "ndisX: couldn't map <foo>" messages that are sometimes emitted during driver load.

Rework resource allocation. Replace the "feel around like a blind man" method with something a little more intelligent: use BUS_GET_RESOURCE_LIST() to run through all resources allocated to us and map them as needed. This way we know exactly what resources need to be mapped and what their RIDs are without having to guess. This simplifies both ndis_attach() and ndis_convert_res(), and eliminates the unfriendly "ndisX: couldn't map <foo>" messages that are sometimes emitted during driver load.

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

- Fix some compiler warnings in subr_pe.c - Add explicit cardbus attachment in if_ndis.c - Clean up after moving bus_setup_intr() in ndis_attach(). - When setting an ssid, program an empty ssid as a 1-byte string with a single 0 byte. The Microsoft documentation says this is how you're supposed to tell the NIC to attach to 'any' ssid. - Keep trace of callout handles for timers externally from the ndis_miniport_timer structs, and run through and clobber them all after invoking the haltfunc just in case the driver left one running. (We need to make sure all timers are cancelled on driver unload.) - Handle the 'cancelled' argument in ndis_cancel_timer() correctly.

Deal with the duplicate sysctl leaf problem. A .inf file may contain definitions for more than one device (usually differentiated by the PCI subvendor/subdevice ID). Each device also has its own tree of registry keys. In some cases, each device has the same keys, but sometimes each device has a unique tree but with overlap. Originally, I just had ndiscvt(8) dump out all the keys it could find, and we would try to apply them to every device we could find. Now, each key has an index number that matches it to a device in the device ID list. This lets us create just the keys that apply to a particular device. I also added an extra field to the device list to hold the subvendor and subdevice ID. Some devices are generic, i.e. there is no subsystem definition. If we have a device that doesn't match a specific subsystem value and we have a generic entry, we use the generic entry.

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.

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.

Clean up ndiscvt a bit (leaving out the -i flag didn't work) and add copyrights to the inf parser files. Add a -n flag to ndiscvt to allow the user to override the default device name of NDIS devices. Instead of "ndis0, ndis1, etc..." you can have "foo0, foo1, etc..." This allows you to have more than one kind of NDIS device in the kernel at the same time. Convert from printf() to device_printf() in if_ndis.c, kern_ndis.c and subr_ndis.c. Create UMA zones for ndis_packet and ndis_buffer structs allocated on transmit.

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.

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 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.

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.

Merge in some changes submitted by Brian Feldman. Among other things, these add support for listing BSSIDs via wicontrol -l. I added code to call OID_802_11_BSSID_LIST_SCAN to allow scanning for any nearby wirelsss nets. Convert from using individual mutexes to a mutex pool, created in subr_ndis.c. This deals with the problem of drivers creating locks in their DriverEntry() routines which might get trashed later. Put some messages under IFF_DEBUG.

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.

Attempt to handle the status field in the ndis_packet oob area correctly. For received packets, an status of NDIS_STATUS_RESOURCES means we need to copy the packet data and return the ndis_packet to the driver immediatel. NDIS_STATUS_SUCCESS means we get to hold onto the packet, but we have to set the status to NDIS_STATUS_PENDING so the driver knows we're going to hang onto it for a while. For transmit packets, NDIS_STATUS_PENDING means the driver will asynchronously return the packet to us via the ndis_txeof() routine, and NDIS_STATUS_SUCCESS means the driver sent the frame, and NDIS (i.e. the OS) retains ownership of the packet and can free it right away.

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

Attempt to handle the status field in the ndis_packet oob area correctly. For received packets, an status of NDIS_STATUS_RESOURCES means we need to copy the packet data and return the ndis_packet to the driver immediatel. NDIS_STATUS_SUCCESS means we get to hold onto the packet, but we have to set the status to NDIS_STATUS_PENDING so the driver knows we're going to hang onto it for a while. For transmit packets, NDIS_STATUS_PENDING means the driver will asynchronously return the packet to us via the ndis_txeof() routine, and NDIS_STATUS_SUCCESS means the driver sent the frame, and NDIS (i.e. the OS) retains ownership of the packet and can free it right away.

Rework mbuf<->ndis_packet/ndis_packet<->mbuf translation a little to make it more robust. This should fix problems with crashes under heavy traffic loads that have been reported. Also add a 'query done' callback handler to satisfy the e100bex.sys sample Intel driver.

Avoid using any of the ndis_packet/ndis_packet_private fields for mbuf<->packet housekeeping. Instead, add a couple of extra fields to the end of ndis_packet. These should be invisible to the Windows driver module. This also lets me get rid of a little bit of evil from ndis_ptom() (frobbing of the ext_buf field instead of relying on the MEXTADD() macro).

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.

Avoid using any of the ndis_packet/ndis_packet_private fields for mbuf<->packet housekeeping. Instead, add a couple of extra fields to the end of ndis_packet. These should be invisible to the Windows driver module. This also lets me get rid of a little bit of evil from ndis_ptom() (frobbing of the ext_buf field instead of relying on the MEXTADD() macro).

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.

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.

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.

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 the definition of the ndis_miniport_interrupt structure: the ni_dpccountlock member is an ndis_kspin_lock, not an ndis_spin_lock (the latter is too big). Run if_ndis.c:ndis_tick() via taskqueue_schedule(). Also run ndis_start() via taskqueue in certain circumstances. Using these tweaks, I can now get the Broadcom BCM5701 NDIS driver to load and run. Unfortunately, the version I have seems to suffer from the same bug as the SMC 83820 driver, which is that it creates a spinlock during its DriverEntry() routine. I'm still debating the right way to deal with this.

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.

Silence irritating watchdog timeout messages: if we call ndis_send_packets() but there's no link yet, we get an immediate callback to ndis_txeof(), which clears if_timer. But ndis_start() sets if_timer right after the call to ndis_send_packets(). Set if_timer before calling ndis_send_packets(). Also fix mutex locking to prevent ndis_txeof() from running in the middle of ndis_start().

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.

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

Silence irritating watchdog timeout messages: if we call ndis_send_packets() but there's no link yet, we get an immediate callback to ndis_txeof(), which clears if_timer. But ndis_start() sets if_timer right after the call to ndis_send_packets(). Set if_timer before calling ndis_send_packets(). Also fix mutex locking to prevent ndis_txeof() from running in the middle of ndis_start().

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

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.

Clean up ndiscvt a bit (leaving out the -i flag didn't work) and add copyrights to the inf parser files. Add a -n flag to ndiscvt to allow the user to override the default device name of NDIS devices. Instead of "ndis0, ndis1, etc..." you can have "foo0, foo1, etc..." This allows you to have more than one kind of NDIS device in the kernel at the same time. Convert from printf() to device_printf() in if_ndis.c, kern_ndis.c and subr_ndis.c.

- Add pe_get_message() and pe_get_messagetable() for processing the RT_MESSAGETABLE resources that some driver binaries have.

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.

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().

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

Clean up ndiscvt a bit (leaving out the -i flag didn't work) and add copyrights to the inf parser files. Add a -n flag to ndiscvt to allow the user to override the default device name of NDIS devices. Instead of "ndis0, ndis1, etc..." you can have "foo0, foo1, etc..." This allows you to have more than one kind of NDIS device in the kernel at the same time. Convert from printf() to device_printf() in if_ndis.c, kern_ndis.c and subr_ndis.c. Create UMA zones for ndis_packet and ndis_buffer structs allocated on transmit. The zones are created and destroyed in the modevent handler in kern_ndis.c. printf() and UMA changes submitted by green@freebsd.org

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.

- Fix some compiler warnings in subr_pe.c - Add explicit cardbus attachment in if_ndis.c - Clean up after moving bus_setup_intr() in ndis_attach(). - When setting an ssid, program an empty ssid as a 1-byte string with a single 0 byte. The Microsoft documentation says this is how you're supposed to tell the NIC to attach to 'any' ssid. - Keep trace of callout handles for timers externally from the ndis_miniport_timer structs, and run through and clobber them all after invoking the haltfunc just in case the driver left one running. (We need to make sure all timers are cancelled on driver unload.) - Handle the 'cancelled' argument in ndis_cancel_timer() correctly.

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.

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.

Clean up ndiscvt a bit (leaving out the -i flag didn't work) and add copyrights to the inf parser files. Add a -n flag to ndiscvt to allow the user to override the default device name of NDIS devices. Instead of "ndis0, ndis1, etc..." you can have "foo0, foo1, etc..." This allows you to have more than one kind of NDIS device in the kernel at the same time. Convert from printf() to device_printf() in if_ndis.c, kern_ndis.c and subr_ndis.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

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

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.

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.

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

Also, avoid trying to set NDIS_80211_AUTHMODE_AUTO since the Microsoft documentation I have recommends not using it, and the Centrino driver seems to dislike being told to use it.
