3488b48a00 Re-add getosreldate(3) function prototype in the form that I've been using
for quite some time now.  While I'm not sure if it'll break IA64 again,
this way doesn't cause problems with my builds of XFree86/Xorg and the way
they #include <osreldate.h> via cpp in the imake system.

767b32095f Use some casting to get the right addresses. This is likely unwise
code, but will be OK until there's a 64-bit siba...

With this change, SENTRY5 kernel now compiles for mips, the last of
the holdouts.

includes syscall32_{de,}register() routines as well as a module handler
and wrapper macros similar to the support for native syscalls in

48a43ae819 Tidy up a few things with syscall generation:
- Instead of using a syscall slot (370) just to get a function prototype
  for lkmressys(), add an explicit function prototype to <sys/sysent.h>.
  This also removes unused special case checks for 'lkmressys' from
  makesyscalls.sh.
- Instead of having magic logic in makesyscalls.sh to only generate a
  function prototype the first time 'lkmnosys' is seen, make 'NODEF'
  always not generate a function prototype and include an explicit
  prototype for 'lkmnosys' in <sys/sysent.h>.
- As a result of the fix in (2), update the LKM syscall entries in
  the freebsd32 syscall table to use 'lkmnosys' rather than 'nosys'.
- Use NOPROTO for the __syscall() entry (198) in the native ABI.  This
  avoids the need for magic logic in makesyscalls.h to only generate
  a function prototype the first time 'nosys' is encountered.

0dae32f2eb Some people's 6to4 routers seem to have been blowing up because of
the unlocked route caching in if_stf. Add a mutex that protects
access to cached route. This seemed to fix problems for Pekka Savola.

Nick Sayer had similar problems, and in his case completly disabling
the route cache seemed to help. Add a sysctl net.link.stf.route_cache
that can be used to turn off route caching in if_stf.

83c04c93b6 Add another hardware bug workaround for Yukon II controllers that
have hardware ram buffer. The silicon bug seem to be triggered by
pause frames if receive buffer is not aligned on FIFO word(8 bytes).
To workaround the issue, make sure to align Rx buffers on 8 bytes.
Unfortunately this workaround requires yet another Rx fixup for
strict alignment architecture machines to align IP header.

For newer hardwares that lacks ram buffer may not have this bug so
check number of available ram buffer size to see the existence of
ram buffer.

d2722d704c Part 1 of making shared lookups more resilient with respect to forced
unmounts.  When we upgrade a vnode lock from shared to exclusive during
a name cache lookup, fail the lookup with EBADF if the vnode is invalidated
while we are waiting for the exclusive lock.

Also, for correctness (though I'm not sure it can occur in practice),
downgrade an exclusively locked vnode if it should be share locked.

4c7428e1ff Fix a crash when calling tty_rel_free() while draining during closure.
Yesterday I got two reports of potential crashes, related to TTY
deallocation during device closure. When a thread is in TF_OPENCLOSE,
draining its output upon closure, we should not allow calls to
tty_rel_free() to happen at the same time. This could cause the TTY to
be torn down twice.

a0ca087183 When dropping a packet and issuing a reset during TCP segment handling,
unconditionally drop the tcbinfo lock (after all, we assert it lines
before), but call tcp_dropwithreset() under both inpcb and inpcbinfo
locks only if we pass in an tcpcb.  Otherwise, if the pointer is NULL,
firewall code may later recurse the global tcbinfo lock trying to look
up an inpcb.

This is an instance where a layering violation leads not only
potentially to code reentrace and recursion, but also to lock
recursion, and was revealed by the conversion to rwlocks because
acquiring a read lock on an rwlock already held with a write lock is
forbidden.  When these locks were mutexes, they simply recursed.
