pci_iov: Clear NumVFs when configuration fails
pci_iov_config() programs NumVFs before validating the final VF RID
layout and allocating all generic resources. A subsequent error ran the
driver uninit callback but left the hardware NumVFs register programmed
while the software VF count returned to zero.
Clear NumVFs in the error path after the driver uninit callback,
matching normal SR-IOV teardown ordering. This prevents stale hardware
state after a failed configuration and permits a clean retry.

pci_iov: Permit non-ARI VFs on a secondary bus
A non-zero VF device number does not always require ARI. The Intel
82576 and I350 [1] explicitly support a non-ARI layout that places VFs
on the next bus.
Check every requested VF RID and reject a non-zero device only when it
is on the PF bus. This retains the ARI guard for invalid same-bus
layouts while permitting the documented second-bus layout.

igb: Address queue registers by hardware queue ID
Use each ring's physical queue index for initialization, MSI-X routing,
register dumps, sysctls, and debug output instead of assuming that its
logical array index is also its hardware index.
This is a no-op for the normal queue layout. A later SR-IOV change
moves the PF ring to hardware queue num_vfs, so its hardware ID then
differs from logical queue zero.

e1000: Update shared igb SR-IOV code
Update the shared e1000 PF/VF mailbox interfaces for an in-tree igb
SR-IOV implementation.
Intel FreeBSD igb-2.5.31 and DPDK provide the older PF/VF mailbox
baseline.
The retained PF mailbox read and explicit unlock operation follow a
simple Linux igb parameter addition to make PF mailbox acquisition
nonblocking so the driver can retry outside the shared primitive.
Treating a CTS-less E1000_PF_CONTROL_MSG as a reset follows DPDK.

iflib: Add restart transactions for IOV reconfiguration
Some devices remap the PF queues when entering or leaving SR-IOV. Add
opt-in PCI IOV helpers that hold the iflib context lock across the
complete stop, driver callback, and restart transaction.
Existing drivers continue to use the non-restarting helpers.

certctl: Enforce 0444 mode on new files
When writing to a file, call fchmod() to ensure the file mode matches
the intended mode, which is 0444. This was already done when replacing
an existing file, but not when creating a new file, which meant if the
process umask was 077, the resulting certificates and bundle would be
unreadable by unprivileged users.

ktls: Propagate EPG_FLAG_ANON to mapped mbufs
Otherwise ktls_mbuf_crypto_state() will reject mbufs created by
_mb_unmapped_to_ext(), which arises when transmitting packets through an

interface in particular.

sdhci: don't infer a non-removable slot on Apollo Lake SDXC
Intel Apollo Lake SDXC controller reports a Slot Type of
"Embedded Slot for One Device" in SDHCI_CAPABILITIES bits, even
when the slot is a removable card reader.

wg(4): Add a test that the driver handles a decryption failure
The test uses a fail point to inject a decryption error in OCF while
sending a ping across the tunnel. The driver should then fail to
respond to the ping and increment the input error counter on the

coredump: Don't assume that the number of ELF segments is consistent
In an ELF coredump, each dumped vm_map_entry is represented by a
segment. __elfN(coredump) first computes the number of segments by
looping over the vm_map entries (in each_dumpable_segment()), then
allocates a buffer to hold the ELF header and program headers, then
loops over the entries again to populate the program headers.
each_dumpable_segment() holds the vm_map read lock, but that lock is
dropped between the two calls. If the map is shared with another
process, via rfork(), then the map can change. cb_put_phdr() did not
account for this, and so could write out of bounds.
Add a check to prevent this; simply do not write out excess segments.

sysvsem: Fix a TOCTOU race in semctl({GET,SET}ALL)
These commands take a snapshot of the size of a semaphore set, then drop
the lock and malloc an appropriately sized array before reacquiring the
lock. A comment explains why this is (probably) safe. Unfortunately,
it's wrong; it is indeed possible for a malicious userspace to create
and destroy 2^{15} sets in the window where the lock is dropped. This
race can lead to out-of-bounds reads and writes, and that can be
exploited to elevate privileges.
Replace the assertions with runtime checks.

kqueue: Avoid enqueuing an already-enqueued knote
knotes with a non-trivial f_copy implementation may be activated before
kqueue_fork_copy_knote() is finished. In particular, it may be enqueued
at the time that kqueue_fork_copy_knote() calls knote_enqueue(). Guard
against this.
Add a test case which triggers the race.
Fix several other problems with the replication of knote state:
- Make sure only the KN_ACTIVE and KN_DISABLED status flags are
inherited, the rest should not be copied.
- Ignore marker knotes.
- Ignore knotes for kqueues. They cannot be safely copied into the
child without more work, as kqueues are inherently local to a process;
on fork, we need to ensure that such knotes are patched to reference
the new kqueue, not the original.
- Try to keep knote state stable by holding the kqueue and knlist locks
while copying.

jail: restore ktrace privileges for jailed root
Commit 4be491e1b9b3 ("jail: Optionally allow audit session state to
be configured in a jail") removed the #if 0 around the audit cases
in prison_priv_check() and added the PR_ALLOW_SETAUDIT check under
them. This unintentionally captured the preceding case PRIV_KTRACE,
which used to fall through the disabled block into the unconditional
return (0) of the credential cases: since then, jailed root only has
ktrace privileges (tracing processes with changed credentials, see
ktrcanset()) when the unrelated allow.setaudit knob is enabled, and
conversely gains them when that audit knob is turned on.
Give PRIV_KTRACE back its own unconditional return (0), matching its
comment and the pre-4be491e1b9b3 behaviour.
