when reaching the zone limit of reassembly queue entries.
When the zone limit was reached not even the missing segment
that would complete the sequence space could be processed
preventing the TCP session forever from making any further
progress.
Solve this deadlock by using a temporary on-stack queue entry
for the missing segment followed by an immediate dequeue again
by delivering the contiguous sequence space to the socket.
Add logging under net.inet.tcp.log_debug for reassembly queue
issues.

raw IP sockets. It was deducted in ip_input() in preparation for
protocols interested only in the payload.
On raw sockets the IP header should be delivered as it at came in
from the network except for the byte order swaps in some fields.
This brings us in line with all other OS'es that provide raw
IP sockets.

It seems I was under the impression that a tab differs from a single
forward tabulation, namely that it blanks the underlying cells. This
seems not to be the case. They are identical.
This should fix applications like jove(1) that use tabs instead of
explicit cursor position setting.

As noted in kern/159780, printf() is not very jail-friendly, since it can't be easily monitored by jail management tools. This patch reports an error via log() instead, which, if nobody is watching the log file, still prints to the console.

So set the overflow value at 0x80000000 and subtract the

heading "kernel panics with RPCSEC_GSS" appears to be caused by a
corrupted tailq list for the client structure. Looking at the code, calls
to the function svc_rpc_gss_forget_client() were done in an SMP unsafe
manner, with the svc_rpc_gss_lock only being acquired in the function
and not before it. As such, when multiple threads called
svc_rpc_gss_forget_client() concurrently, it could try and remove the
same client structure from the tailq lists multiple times.
The patch fixes this by moving the critical code into a separate
function called svc_rpc_gss_forget_client_locked(), which must be
called with the lock held. For the one case where the caller would
have no interest in the lock, svc_rpc_gss_forget_client() was retained,
but a loop was added to check that the client structure is still in
the tailq lists before removing it, to make it safe for multiple
concurrent calls.

Skip the TCP_SIGNATURE check in that case as it is consistent with the
output path (no TCP_SIGNATURE for outcoming packets in TIMEWAIT state)
and also because for TIMEWAIT state the verify may be less effective.

itself, which sparc64 hardware doesn't support. One way to solve this
would be to directly call sched_preempt() instead of issuing a self-IPI.
However, quoting jhb@:
"On the other hand, you can probably just skip the IPI entirely if we are
going to send it to the current CPU. Presumably, once this routine
finishes, the current CPU will exit softlock (or will do so "soon") and
will then pick the next thread to run based on the adjustments made in
this routine, so there's no need to IPI the CPU running this routine
anyway. I think this is the better solution. Right now what is probably
happening on other platforms is as soon as this routine finishes the CPU
processes its self-IPI and causes mi_switch() which will just switch back
to the softclock thread it is already running."
- With r226054 and the the above change in place, sparc64 now no longer is
incompatible with ULE and vice versa. However, powerpc/E500 still is.

valid - we don't allow for setting it on a file, for example - but it's
not something we should assert on.
For STABLE kernel, it changes nothing, because it's not compiled with
INVARIANTS. If it was, it would fix crashes. It also fixes an assert
in libc encountered with NFSv4 without nfsuserd(8) running.

regex library is not replaced so that BSD grep development can continue
and the backported code gets some review and testing. This change only
improves scalability slightly, there is no big performance boost yet
but several minor bugs have been found and fixed.
