When we guess the nature of the outbound packet (output vs. forwarding) we need
to take bridges into account. When bridging the input interface does not match
the output interface, but we're not forwarding. Similarly, it's possible for the
interface to actually be the bridge interface itself (and not a member interface).

This is several year's worth of fail point upgrades done at EMC Isilon. They
are interdependent enough that it makes sense to put a single diff up for them.
Primarily, we added:
- Changing all mainline execution paths to be lockless, which lets us use fail
points in more sleep-sensitive areas, and allows more parallel execution
- A number of additional commands, including 'pause' that lets us do some
interesting deterministic repros of race conditions
- The ability to dump the stacks of all threads sleeping on a fail point
- A number of other API changes to allow marking up the fail point's context in
the code, and firing callbacks before and after execution
- A man page update

Specifically this fixes /usr/lib/libc.so stripping the paths to the
libraries. The reason for this in r266227 was both likely because ld(1) did
not fully respect --sysroot until r291226 and because of the lib32
build. The lib32 build does not use --sysroot into the /usr/lib32 path,
rather it only uses -L and -B into the /usr/lib32 path and --sysroot
into the normal (64bit) /usr/lib. The _LDSCRIPTROOT was added with
the ldscript support in bsd.lib.mk so that it builds a 32-bit-sysrooted pathed
ldscript in the object directory and then installs a normal unprefixed
version in installworld. This commit also fixes the rebuild during
install which was broken in r266227. This commit would break DIRDEPS_BUILD
build of lib32 but it does not currently have a way to build it anyhow.
For example, before this change we had in /usr/lib/libc.so:
GROUP ( libc.so.7 libc_nonshared.a libssp_nonshared.a )
Now it is restored to pre-r266227:
GROUP ( /lib/libc.so.7 /usr/lib/libc_nonshared.a /usr/lib/libssp_nonshared.a )
The motivation for this is in testing of lld.
From emaste:
lld does not have built-in search paths (e.g. /lib, /usr/lib) and relies on
-L arguments passed by the caller. As the linker is nearly always invoked
from the clang driver this is fine other than the fact that /usr/lib/libc.so
is an ldscript that refers to libc.so.7 which is in /lib, not /usr/lib.

Use the Toeplitz hash value as source for the flowid. This makes the
hash value more suitable for so-called hash bucket algorithms which
are used in the FreeBSD's TCP/IP stack when RSS is enabled.

ipoib module.
The bpfdetach() function is trying to turn off promiscious mode on the
network interface it is attached to while holding a mutex. The fix
consists of ignoring any further calls to the ipoib_ioctl() function
when the network interface is going to be detached. The ipoib_ioctl()
function might sleep.

non-multiple of 64 bytes. Thereafter, the user state save area is
misaligned, which triggers assertion in the debugging kernels, or
segmentation violation on accesses for non-debugging configs.
Force the desired alignment of the user save area as the fix
(workaround is to disable bit 9 in the hw.xsave_mask loader tunable).
This correction is required for booting on the upcoming Intel' Purley
platform.

support frameworks(i.e. clk/reset/phy/tsensors/fuses...).
The framework is still far from perfect and probably doesn't have stable
interface yet, but we want to start testing it on more real boards and
different architectures.
The standards in the QSFP diagnostics area are not clear when the

Keymap header files have historically been generated using the build
host's /usr/sbin/kbdcontrol and using the host's keymap files.
However, that introduces an issue when building a kernel to use vt(4)
on a system using sc(4), or vice versa: kbdcontrol searches for keymap
files in the /usr/share subdirectory appropriate for the host, not the
target.
With this change the build searches both the and sc keymap directories
from the source tree.

struct tcpstat, because the structure can be zeroed out by netstat(1) -z,
and of course running connection counts shouldn't be touched.
Place running connection counts into separate array, and provide
separate read-only sysctl oid for it.
When finger is invoked as as "finger username", it produces the
long listing by default, and phones numbers are pretty-printed
by the prphone() function. When invoked as just "finger", the
same pretty-printing happens, but is truncated at 9 characters.
Given the summary listing is already greater than 80 columns,
making it even wider is of no harm.
