If net.link.bridge.pfil_bridge is set we can end up thinking we're forwarding in
pf_test6() because the rcvif and the ifp (output interface) are different.
In that case we're bridging though, and the rcvif the the bridge member on which
the packet was received and ifp is the bridge itself.
If we'd set dir to PF_FWD we'd end up calling ip6_forward() which is incorrect.
Instead check if the rcvif is a member of the ifp bridge. (In other words, the
if_bridge is the ifp's softc). If that's the case we're not forwarding but
bridging.

on the Variant II code, however arm64 uses Variant I. The former placed the
thread pointer after the data, pointing at the thread control block, while
the latter places these before said data.
Because of this we need to use the size of the previous entry to calculate
where to place the current entry. We also need to reserve 16 bytes at the
start for the thread control block.
This also fixes the value of TLS_TCB_SIZE to be correct. This is the size
of two unsigned longs, i.e. 2 * 8 bytes.
While here remove the bogus adjustment of the pointer in the
R_AARCH64_TLS_TPREL64 case. It should be the offset of the data relative
to the thread pointer, including the thread control block.

have TLS program header. This is needed on architectures with Variant I
tls, that is arm, arm64, mips, and powerpc. These place the thread control
block at the start of the buffer and, without this, this data may be
trashed.
This appears to not be an issue on mips or powerpc as they include a second
adjustment to move the thread local data, however this is on arm64 (with a
future change to fix placing this data), and should be on arm. I am unable
to trigger this on arm, even after changing the code to move the data
around to make it more likely to be hit. This is most likely because my
tests didn't use the variable in offset 0.

particular, this invalidates the knote kn_link linkage, making the
SLIST_FOREACH() loop accessing undefined values (e.g. trashed by
QUEUE_MACRO_DEBUG). If the knote is freed by other thread when kq
lock is released or when influx is cleared, e.g. by knote_scan() for
kqueue owning the knote, the iteration step would access freed memory.
Use SLIST_FOREACH_SAFE() to fix iteration.

of the D_NEWBLK kinds of dependencies (i.e. D_ALLOCDIRECT and
D_ALLOCINDIR), which can exhaust kmem.
Handle excess of D_NEWBLK in the same way as excess of D_INODEDEP and
D_DIRREM, by scheduling ast to flush dependencies, after the thread,
which created new dep, left the VFS/FFS innards. For D_NEWBLK, the
only way to get rid of them is to do full sync, since items are
attached to data blocks of arbitrary vnodes. The check for D_NEWBLK
excess in softdep_ast_cleanup_proc() is unlocked.
For 32bit arches, reduce the total amount of allowed dependencies by
two. It could be considered increasing the limit for 64 bit platforms
with direct maps.

Connect it to the build.
The code assumed that SCHED_* constants form a contiguous set of
numbers, remove the assumption by using schedulers[] array in
get_different_scheduler(). This is no-op on FreeBSD, but improves
code portability.
The selection of different priority used the min/max priority range of
the current scheduler class, instead of the priority to be changed to.
The bug caused the test failure.
Remove duplication of POSIX_SPAWN_SETSIGDEF flag and now unused
duplications of MIN/MAX definitions.

The typo was introduced in r278469 / 344ecf88af.
As a result of the bug there was a timing window where callout_reset()
would fail to cancel a concurrent execution of a callout that is about
to start and would schedule the callout again.
The callout would fire more times than it is scheduled.
That would happen even if the callout is initialized with a lock.
For example, the bug triggered the "Stray timeout" assertion in
taskqueue_timeout_func().
