07c006c6fb Add support for newer integrated SiS 900 controllers on the 635 and 735
motherboard chipsets. We need to force the chip to reload its MAC address
into the receive filter, and enable software access mode for the PHY.

0bc7a833ec When going to sleep, we must save our SPL so that it does not get
lost if some other process uses the lock while we are sleeping. We
restore it after we have slept. This functionality is provided by
a new routine interlocked_sleep() that wraps the interlocking with
functions that sleep. This function is then used in place of the
old ACQUIRE_LOCK_INTERLOCKED() and FREE_LOCK_INTERLOCKED() macros.

5df3797ebf Fix a few NFSv2 issues that slipped in during the big cleanup. The
semantics of the nfsm_reply() macro were changed so that the caller
has to explicitly handle the V2 error case, whereas before,
nfsm_reply() did a `goto nfsmout' then. A few server ops (setattr,
readlink, create, mkdir) weren't updated to match, so errors in the
V2 case could cause protocol hangs and leaked mbufs.

Correct some comments that describe the old nfsm_reply behaviour.

[older, harmless nit] Remove the unnecessary `nfsmreply0' label in
nfsrv_create(), since for its users, the main `ereply' label does
the same thing.

66b462a989 The macro nfsm_reply() is supposed to allocate a reply in all cases,
but since the nfs cleanup, it hasn't done so in the case where
`error' is EBADRPC. Callers of this macro expect it to initialise
*mrq, and the `nfsmout' exit point expects a reply to be allocated
if error == 0. When nfsm_reply() was called with error = EBADRPC,
whatever junk was in *mrq (often a stale pointer to an old reply
mbuf) would be assumed to be a valid reply and passed to pru_sosend(),
causing a crash sooner or later.

Fix this by allocating a reply even in the EBADRPC case like we
used to do. This bug was specific to -current.

76980afbc0 I don't think that these modules should export symbols at all. All
intermodule communication is done via kobj calls.  If anything
currently depends on them, let it break so that we can fix it.  Maybe
we'll need to export some of the card_if.c or power_if.c symbols, but
I think those should be in the base kernel (since all *_if.c should be
in the base kernel for just these reasons).

52e85481fd Make the alpha boot1 work on filesystems that have a block size
larger than 8k. We now use 4k buffers regardless of the filesystem
block size, so there is no longer a static limit.

Simply increasing the buffer size from 8k to 16k as done on the
i386 doesn't work on the alpha, probably because it causes us
to overshoot boot1's 48k runtime memory limit.

9c643340bb Do not pull quota entries of the cache-list if they have already
been removed from the cache-list as part of a previous unmount.

This would result in panics (page fault in dqflush()) during subsequent
umounts provided that enough distinct UID's to actually make the
hash do something are active.

This can probably explain a number of weird quota related behaviours.

traps on the first instruction of signal handlers.

In trap.c:syscall(), fake a trace trap if the single-step flag was set
on entry to the kernel, not if it will be set on exit from the kernel.
This fixes bogus trace traps after the last instruction of signal handlers.

gdb-4.18 (the version in FreeBSD) still has problems with the program in

0b3178a45c Eliminate the use of commons in the kernel and modules,
simplifying the module linking process and eliminating the risks
associated with doubly-defined variables.

Cases where commons were legitimately used (detection of
compiled-in subsystems) have been converted to use sysinits, and
any new code should use this or an equivalent practice as a
matter of course.

Modules can override this behaviour by substituting -fno-common
out of ${CFLAGS} in cases where commons are necessary
(eg. third-party object modules).  Commons will be resolved and
allocated space when the kld is linked as part of the module
build process, so they will not pose a risk to the kernel or
other modules.

Provide a mechanism for controlling the export of symbols from
the module namespace.  The EXPORT_SYMS variable may be set in the
Makefile to NO (export no symbols), a list of symbols to export,
or the name of a file containing a newline-seperated list of
symbols to be exported.  Non-exported symbols are converted to
local symbols.  If EXPORT_SYMS is not set, all global symbols are
currently exported.  This behaviour is expected to change (to
exporting no symbols) once modules have been converted.

a7f6ff2e8c Terminate requests in nfs_sigintr() if the filesystem is in the
process of being unmounted. This allows forced NFS unmounts to
complete even if there are processes stuck holding the mnt_lock
while the server is down. The mechanism is not ideal in that there
is a small chance we might accidentally cancel requests during a
failed non-forced unmount attempt on that filesystem, but this
is not really a big problem.

Also, move the tsleep() in nfs_nmcancelreqs() so that we do not
sleep in the case where there are no requests to be cancelled.

data word in an interrupt packet is non-zero, it points to code to execute
to handle the ipi, so jump to it instead of enqueueing the packet.  It
is unclear if we will need queued ipis.
Interrupt g7 now points to pcpu, instead of to the per-cpu interrupt queue
itself, so use that instead.  Interrupt g6 is no longer reserved.

f8efde8991 - Teach SIGIO code to use cr_cansignal() instead of a custom CANSIGIO()
macro.  As a result, mandatory signal delivery policies will be
  applied consistently across the kernel.

- Note that this subtly changes the protection semantics, and we should
  watch out for any resulting breakage.  Previously, delivery of SIGIO
  in this circumstance was limited to situations where the subject was
  privileged, or where one of the subject's (ruid, euid) matched one
  of the object's (ruid, euid).  In the new scenario, subject (ruid, euid)
  are matched against the object's (ruid, svuid), and the object uid's
  must be a subset of the subject uid's.  Likewise, jail now affects
  delivery, and special handling for P_SUGID of the object is present.
  This change can always be reversed or tweaked if it proves to disrupt
  application behavior substantially.

c83f8015fa - Push much of the logic for p_cansignal() behind cr_cansignal, which
authorized based on a subject credential rather than a subject process.
  This will permit the same logic to be reused in situations where only
  the credential generating the signal is available, such as in the
  delivery of SIGIO.
- Because of two clauses, the automatic success against curproc,
  and the session semantics for SIGCONT, not all logic can be pushed
  into cr_cansignal(), but those cases should not apply for most other
  consumers of cr_cansignal().
- This brings the base system inter-process authorization code more
  into line with the MAC implementation.

c86b6ff551 Change the preemption code for software interrupt thread schedules and
mutex releases to not require flags for the cases when preemption is
not allowed:

The purpose of the MTX_NOSWITCH and SWI_NOSWITCH flags is to prevent
switching to a higher priority thread on mutex releease and swi schedule,
respectively when that switch is not safe.  Now that the critical section
API maintains a per-thread nesting count, the kernel can easily check
whether or not it should switch without relying on flags from the
programmer.  This fixes a few bugs in that all current callers of
swi_sched() used SWI_NOSWITCH, when in fact, only the ones called from
fast interrupt handlers and the swi_sched of softclock needed this flag.
Note that to ensure that swi_sched()'s in clock and fast interrupt
handlers do not switch, these handlers have to be explicitly wrapped
in critical_enter/exit pairs.  Presently, just wrapping the handlers is
sufficient, but in the future with the fully preemptive kernel, the
interrupt must be EOI'd before critical_exit() is called.  (critical_exit()
can switch due to a deferred preemption in a fully preemptive kernel.)

I've tested the changes to the interrupt code on i386 and alpha.  I have
not tested ia64, but the interrupt code is almost identical to the alpha
code, so I expect it will work fine.  PowerPC and ARM do not yet have
interrupt code in the tree so they shouldn't be broken.  Sparc64 is
broken, but that's been ok'd by jake and tmm who will be fixing the
interrupt code for sparc64 shortly.

1278d57acd Permit NFS filesystems to be forcibly unmounted when the server is
down, even if there are hung processes and the mount is non-
interruptible.

This works by having nfs_unmount call a new function nfs_nmcancelreqs()
in the FORCECLOSE case. It scans the list of outstanding requests
and marks as interrupted any requests belonging to the specified
mount. Then it waits up to 30 seconds for all requests to terminate.
A few other changes are necessary to support this:
- Unconditionally set a socket timeout so that even hard mounts
  are guaranteed to occasionally check the R_SOFTTERM flag on
  requests. For hard mounts this flag can only be set by
  nfs_nmcancelreqs().
- Reject requests on a mount that is currently being unmounted.
- Never grant the receive lock to a request that has been cancelled.

This should also avoid an old problem where a forced NFS unmount
could cause a crash; it occurred when a VOP on an unlocked vnode
(usually VOP_GETATTR) was in progress at the time of the forced
unmount.

for certain user pages, stores to kernel pages would not update the
affected cache lines, which would sometimes cause the wrong data to be
returned for loads from kernel pages.  This was especially fatal when
the addresses affected held the kernel stack pointer, and a random
value was loaded into it.
Fix a harmless off by one error in a dcache_inval_phys call.

cbe522d307 Implement user trap delivery as specified by the sparc abi. This provides
an efficient way for the kernel to bounce certain mundane traps back to
userland for handling there.  A user trap handler returns directly to the
trapping user code, rather than going through the kernel again.  Only a
handful of instructions are actually executed in kernel mode.
Implement sysarch(SPARC_UTRAP_INSTALL).
Add code to handle sharing of the user trap table across forks and unsharing
at exec.

This can be used to implement efficient tracking of floating point register
usage in userland, fe by a thread library, and to handle alignment fault
fixups and instruction emulation in userland, for which the code may need
to be different for 32bit and 64bit binaries.

0d6fcb5c0e Fix bugs in the structure for rx_frame by making gap length one byte and
a packed array so sizeof work.  This broke RFMON mode and passing
up 802.11 packets.

The Linux emulation code was derived from the open source Linux driver to
maintain compatibility.

LEAP support is added, hints from Richard Johnson.  I've verified this
locally with PC350v42510.img firmware.  More bug fixing from Marco to
fix long passwords.

Change DELAYs in flash part of driver to FLASH_DELAY which uses tsleep
so it doesn't look like your system died during a flash update.

Install header files in /usr/include/dev/an

Cleanup some ifmedia bugs add "Home" key mode to ifmedia and ancontrol.
This way you can manage 2 keys a little easier.  Map the home mode into
key 5.  Enhance ifconfig to dump the various configured SSIDs.  I use
a bunch of different ones and roam between them.  Use the syntax similar
to the WEP keys to deal with setting difference SSIDs.

Bump up up the Card capabilities RID since they added 2 bytes to it
in the latest firmware.  Thankfully we changed it from a terminal
failure so the card still worked but the driver whined.

Some cleanup patches from Marco Molteni.

ee037f26bc Implement an option to administratively disable the negotiation of
IPv6 on an sppp interface.  In an IPv6-enabled kernel, every IPv6
interface automatically gets an IPv6 address assigned (and IPv6
multicast packets sent at initialization time).  For sppp links where
we know our remote peer wouldn't support IPv6 at all, there's no point
in attempting to negotiate IPV6CP (or to even dial out for an IPv6
packet at all for dial-on-demand interfaces).

I wish there were a more generic way to administratively disable IPv6
on an interface instead.  ume told me there isn't.

While i was at it, converted both, enable_vj and enable_ipv6 into flag
bits in struct sppp (enable_vj used to be an int of its own).

64b158ad3c Fix the handling of VJ uncompression. Unfortunately, tcp_uncompress()
makes the implied assumption there were another 128 bytes of space in
front of the packet handed off to it... which is not the case for
sppp.  This could easily end up in corrupting random memory.

This fix is about the same as revs 1.6, 1.8, and 1.9 from our
i4b_ispppsubr.c.

Also fixed IPCP option negotiation to zero out the options when
starting IPCP.  Otherwise, if negotiation parameters change between
various IPCP startups, it could happen that old options would still be
requested (this happened if VJ was turned off, and ended up in half
off the link still negotiating for VJ compression).

IMHO, the base system's sppp is now feature-wise up to date with the
one in the i4b part of the tree, so the latter can be disabled.
