55971c63cd Some minor touchups:
In NdisQueryBuffer() and NdisQueryBufferSafe(), the vaddr argument is
optional, so test it before trying to dereference it.

Also correct NdisGetFirstBufferFromPacket()/NdisGetFirstBufferFromPacketSafe():
we need to use nb_mappedsystemva from the buffer, not nb_systemva.

d7d29b16e0 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.

b4f5e8d8cd 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.

a22ec80ece 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.

d3eb09f083 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.

7359dfc0b1 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.

8f0387a278 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.

d7e92f7b85 In NDIS 5.1 miniport drivers, the shutdown handler function pointer
is provided to NDIS via the the miniport characteristics structure
supplied in the call to NdisMRegisterMiniport(). But in NDIS 5.0
and earlier, you had to call NdisMRegisterAdapterShutdownHandler()
and supply both a function pointer and context pointer.

We try to handle both cases in ndis_shutdown_nic(). If the
driver registered a shutdown routine and a context,then used
that context, otherwise pass it the adapter context from
NdisMSetAttributesEx().

This fixes a panic on shutdown with the sample Intel 82559 e100bex.sys
driver from the Windows DDK.

c854fc1092 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

place mappings at sensible locations when limits have been reduced.

Have the imgact_elf.c ld-elf.so.1 placement algorithm use the same

Note that we cannot remove all references to the sysctl tweakable

of 'unlimited'.  And that causes exec etc to fail since it can no
longer find space to mmap things.

34eec0a169 Restored a non-egregious cast so that this file compiles on i386's
with 64-bit longs again.  This was fixed in rev.1.42 but the fix
rotted non-fatally in rev.1.105 and fatally in rev.1.137.

Many more non-egregrious casts are strictly required for conversions
from semi-opaque types to pointers, but we avoid most of them by using
types that are almost certain to be compatible with uintptr_t for
representing pointers (e.g., vm_offset_t).  Here we don't really want
the u_longs, but we have them because a.out.h and its support code
doesn't use typedefs (it uses unsigned in V7 and unsigned long in
FreeBSD) and is too obsolete to fix now.

By giving the vnode a speparate field, a number of checks for the specific
subtype can be replaced simply with a check for f_vnode != NULL, and
we can later free f_data up to subtype specific use.

At this point in time, f_data still points to the vnode, so any code I

d85631c4ac Add BASIC i386 binary support for the amd64 kernel. This is largely
stolen from the ia64/ia32 code (indeed there was a repocopy), but I've
redone the MD parts and added and fixed a few essential syscalls.  It
is sufficient to run i386 binaries like /bin/ls, /usr/bin/id (dynamic)
and p4.  The ia64 code has not implemented signal delivery, so I had
to do that.

Before you say it, yes, this does need to go in a common place.  But
we're in a freeze at the moment and I didn't want to risk breaking ia64.
I will sort this out after the freeze so that the common code is in a
common place.

On the AMD64 side, this required adding segment selector context switch
support and some other support infrastructure.  The %fs/%gs etc code
is hairy because loading %gs will clobber the kernel's current MSR_GSBASE
setting.  The segment selectors are not used by the kernel, so they're only
changed at context switch time or when changing modes.  This still needs
to be optimized.

This is a patch to move the common parts of linux_getcwd() back into

extended functionality.  The linux syscall linux_getcwd() in
compat/linux/linux_getcwd.c has been rewritten to use it too.  It should
be possible to simplify libc's getcwd() after this.  No doubt this code

48e3128b34 Bow to the whining masses and change a union back into void *. Retain
removal of unnecessary casts and throw in some minor cleanups to see if
anyone complains, just for the hell of it.

cd72f2180b Change struct file f_data to un_data, a union of the correct struct
pointer types, and remove a huge number of casts from code using it.

Change struct xfile xf_data to xun_data (ABI is still compatible).

If we need to add a #define for f_data and xf_data we can, but I don't
think it will be necessary.  There are no operational changes in this
commit.
