c73f70b728 o Plug memory leak in syncache_add() on MAC label allocation failure.
o Simplify code flow with 'done' goto label.
o Remove mbuf argument from syncache_respond().  It doesn't make use
  of it.

when one of links is inactive and have stale sequence number. To avoid
this sequence numbers of all links are getting updated on every

fd58342c26 - Fixed mistakes in latency and xmitBytes calculation math
which lead to ineffective multilink packet distribution plans.
- Changed bytesInQueue calculation math to have more precise information
about links utilization.
- Taken rough account of the link overhead. Better way to do it could be to
get exact overhead from user-level, but I have not done it to keep
binary compatibility.

164554dec4 In some cases, like whenever devfs file times are zero, the fix(aa) will not
be applied to dev entries.  This leaves us with file times like "Jan 1 1970."
Work around this problem by replacing the tv_sec == 0 check with a
<= 3600 check.  It's doubtful anyone will be booting within an hour of the
Epoch, let alone care about a few seconds worth of nonzero timestamps.  It's
a hackish work around, but it does work and I have not experienced any
negatives in my testing.

7628acd8ee Up until now, the free SCB pool received only a small initial allocation,
and new SCBs were allocated on demand later if needed.  This has two
problems.  First, allocating SCBs involves allocating contiguous memory,
and if memory is exhausted then the VM will try to page out to satisfy
the request, leading to recursion and deadlock.  The second problem is
that it can cause lock order reversals due to parts of the VM still being
under Giant.

Fix the problem be allocating the full pool at driver attach, when it is
safe to do so.

18a6073100 Make inet6_rth_* family of functions more compliant with RFC3542:
1. CMSG_NXTHDR(mhdr, cmsg) is supposed to dereference cmsg and return
   the next header in the chain. If cmsg is NULL it should return
   the first header, behaving essentially like CMSG_FIRSTHDR().
2. inet6_rth_(space|init|add) should do basic checking on their input
   to verify that the number of headers (segments) is
   between 0 and 127 inclusive.

382d30cdd8 Fix witness(4) warnings about mutex use.
Group mutexes used in hwpmc(4) into 3 "types" in the sense of
witness(4):

 - leaf spin mutexes---only one of these should be held at a time,
   so these mutexes are specified as belonging to a single witness
   type "pmc-leaf".

 - `struct pmc_owner' descriptors are protected by a spin mutex of
   witness type "pmc-owner-proc".  Since we call wakeup_one() while
   holding these mutexes, the witness type of these mutexes needs
   to dominate that of "sleepq chain" mutexes.

 - logger threads use a sleep mutex, of type "pmc-sleep".

fb1daf8164 Fix a bug in sendfile(2) when files larger than page size and nbytes=0.
When nbytes=0, sendfile(2) should use file size. Because of the bug, it
was sending half of a file. The bug is that 'off' variable can't be used
for size calculation, because it changes inside the loop, so we should
use uap->offset instead.

gets a bogus irq storm detected when periodic daily kicks off at 3 am
and disconnects the disk.  Change the print logic to print once per second
