The code was performing an avoidable check for doomed state to account
for foo being a VDIR but turning VBAD. Now that dooming puts a vnode
in a permanent "modify" state this is no longer necessary as the final
status check will catch it.
A long-standing bug in Pass 1 of fsck_ffs in which it is reading in
blocks of inodes to check their block pointers. It failed to round
up the size of the read to a disk block size. When disks would
accept 512-byte aligned reads, the bug rarely manifested itself.
But many recent disks will no longer accept 512-byte aligned reads
but require 4096-byte aligned reads, so the failure to properly
round-up read sizes to multiples of 4096 bytes makes the error
much more likely to occur.

It is best for auditing of syscalls.master if we only append to the
file. Reserving unimplemented system call numbers for local use makes
this policy and provides a large set of syscall numbers FreeBSD
derivatives can use without risk of conflict.

Merge commit 740a164de from llvm git (by Richard Smith):
PR46377: Fix dependence calculation for function types and typedef
types.
We previously did not treat a function type as dependent if it had a
parameter pack with a non-dependent type -- such a function type depends
on the arity of the pack so is dependent even though none of the
parameter types is dependent. In order to properly handle this, we now
treat pack expansion types as always being dependent types (depending on
at least the pack arity), and always canonically being pack expansion
types, even in the unusual case when the pattern is not a dependent
type. This does mean that we can have canonical types that are pack
expansions that contain no unexpanded packs, which is unfortunate but
not inaccurate.
We also previously did not treat a typedef type as
instantiation-dependent if its canonical type was not
instantiation-dependent. That's wrong because instantiation-dependence
is a property of the type sugar, not of the type; an
instantiation-dependent type can have a non-instantiation-dependent
canonical type.

PR46637: Fix handling of placeholder types in trailing-return-types.
Only permit a placeholder type in a trailing-return-type if it would
also have been permitted in the decl-specifier sequence of a
corresponding declaration with no trailing-return-type. The standard
doesn't actually say this, but this is the only thing that makes sense.
Also fix handling of an 'auto' in a trailing-return-type in a parameter
of a generic lambda. We used to crash if we saw such a thing.

This node is part of an A10-NSP (L2-BSA) development.
Carrier networks tend to stack three or more tags for internal
purposes and therefore hiding the service tags deep inside of the
stack. When decomposing such an access network frame, the processing
order is typically reversed: First distinguish by service, than by
other means.
This new netgragh node allows to bring the relevant VLAN in front (to
the out-most position). This way other netgraph nodes (like ng_vlan)
can operate on this specific type.

With clearing of recover_fs in bc7ee8e5bc, div/0

Suspect that rewind of an erraneous RTO may be
causing this - with the above change, recover_fs
would no longer retained at the last calculated
value, and reset. But CC_RTO_ERR can reenable
IN_RECOVERY(), without setting this again.

When diff hits certain access errors, function diffreg() shows the error
message, and then returns to the calling function, which calls
print_status() with the return value.
However, in these cases, the return value isn't changed from the initial
default value of D_SAME.
Normally, print_status() with a value of D_SAME does nothing, so this
works out ok, however, if the "-s" flag is set, a message is displayed
showing identicality:
case D_SAME:
if (sflag)
printf("Files %s%s and %s%s are identical\n", path1, entry, path2, entry);
break;
This then produces such results as:
% diff -s /COPYRIGHT /var/run/rpcbind.sock
diff: /var/run/rpcbind.sock: Operation not supported
Files /COPYRIGHT and /var/run/rpcbind.sock are identical
% diff -s /COPYRIGHT /etc/master.passwd
diff: /etc/master.passwd: Permission denied
Files /COPYRIGHT and /etc/master.passwd are identical
Create a D_ERROR status which is returned in such cases, and
print_status() then deals with that status seperately from D_SAME

These tests are basic fuzz tests that permute input to trigger crashes
rather than regression or unit tests. Additionally, some of them take a
rather long time to run and should probably be run on a dedicated fuzzing
job instead. Moreover, these simple tests use rand() instead of a real
fuzzing tool that generates interesting inputs (e.g. LLVM libFuzzer) so are
unlikely to find anything interesting when run in CI.
This allows removing one BROKEN_TESTS case due to timeouts and speeds up
running tests on emulated platforms such as QEMU.
