Some of the sanitizers from compiler-rt can use ignore lists, which are
loosely modeled on valgrind's example. Upstream provides default lists
for AddressSanitizer, CFI, and MemorySanitizer, so install these in the
expected location, /usr/lib/clang/14.0.3/share.

When a NFSv4.1/4.2 session to the NFS server (not a pNFS DS) is
replaced, the old session should always be marked defunct by
nfsess_defunct being set non-zero.
However, the hang reported by the PR suggests that this might
be the case.
This patch adds a printf() to indicate this has somehow happened.

The NFSERR_BADSESSION reply from a NFSv4.1/4.2 server
is handled by newnfs_request(). It should not be handled
separately after newnfs_request() has returned.
These two cases were spotted during code inspection.
One of them should only redo what newnfs_request() already
did by the same "nfscl" thread. The other might have
resulted in recovery being done twice, but the code is
only used for "pnfs" mounts, so that would be rare.
Also, since NFSERR_BADSESSION should only be replied by
a server after the server reboots, this would be extremely
rare.

Historically only minimal checks were made of a superblock when it
was read in as it was assumed that fsck would have been run to
correct any errors before attempting to use the filesystem. Recently
several bug reports have been submitted reporting kernel panics
that can be triggered by deliberately corrupting filesystem superblocks,
see Bug 263979 - [meta] UFS / FFS / GEOM crash (panic) tracking
which is tracking the reported corruption bugs.
This change upgrades the checks that are performed. These additional
checks should prevent panics from a corrupted superblock. Although
it appears in only one place, the new code will apply to the kernel
modules and (through libufs) user applications that read in superblocks.

PR45879: Fix assert when constant evaluating union assignment.
Consider the form of the first operand of a class assignment not the
second operand when implicitly starting the lifetimes of union members.
Also add a missing check that the assignment call actually came from a
syntactic assignment, not from a direct call to `operator=`.

With M_EXTPG mbufs these two counters already do not represent the
reality. As we are moving towards protocol independent socket buffers,
which may not even use mbufs at all, the counters become less and less
relevant. The only userland seeing them was 'netstat -x'.

Provide sticky ARP flag for network interface which marks it as the
"sticky" one similarly to what we have for bridges. Once interface is
marked sticky, any address resolved using the ARP will be saved as a
static one in the ARP table. Such functionality may be used to prevent
ARP spoofing or to decrease latencies in Ethernet networks.
The drawbacks include potential limitations in usage of ARP-based
load-balancers and high-availability solutions such as carp(4).
The implemented option is disabled by default, therefore should not
impact the default behaviour of the networking stack.

how generic and uninformative EINVAL is, the EMSGSIZE is more

Changing the printf specifier to %p fixed the build on powerpc64, but it
actually broke the amd64 build since the type of the value to be printed
is uint64_t on amd64.
Instead, keep the new %p specifier but cast the printed argument to a
uintptr_t and then to a void * in order for it to be valid type for
%p.

Just invoke the test program directly instead of trying to convert its
output to TAP format. The test suite is all or nothing; there's no way
to enumerate individual test cases, so there's no advantage in trying to
massage its output, and doing so throws away information that's useful
when diagnosing test failures.

One of the tests exposes the regression reported in PR 264131.
One test is disabled because FreeBSD does not support setting EV_ONESHOT
on an already-added periodic timer. Though, in this case the flag is
simply ignored, which isn't ideal.
One test is slightly modified to set EV_ADD when reconfiguring a
disabled timer per some commentary in PR 258412.
Ideally we would re-import the test suite from libkqueue but there is a
fair bit of divergence so this will require some effort. This just gets
us one small step closer while increasing test coverage.

Suppose a periodic kevent timer fires close to its deadline, so that
now - kc->next is small. Then delta ends up being 1, and the next timer
deadline is set to (delta + 1) * kc->to, where kc->to is the timer
period. This means that the timer fires at half of the requested rate,
and the value returned in kn_data is similarly inaccurate.
