db/hash.c: Allow O_WRONLY in dbm_open
The dbm(3) manpage explicitly states that O_WRONLY is not allowed in
dbm_open, but a more recent comment in ` __hash_open` suggests otherwise.
Furthermore, POSIX.1 allows O_WRONLY in dbm_open and states
that the underlying file must be opened for both reading and writing.
Fix this by correcting the O_WRONLY check and moving it further into
the function to make sure that the original flags are stored in hashp.

find: Put back clearing the NOSTAT bit
In fd186cd16eaf I read the condition backwards. We want to stat all the
time until we can implement something to do it more inteligently as
Jiles suggested in the review.

makefs: zfs dataset mountpoints are considered non-empty
The dataset mountpoints get link count and size calculated by
content of dataset root directory, but this will break libzfs
dir_is_empty_stat() test.
For fix, we need to check if the directory is mountpoint for
dataset, and calculate the link count and size accordingly.

Add include sys/param.h
dsl_dir_alloc() needs to set parent = NULL to silence warning
about 'parent' may be used uninitialized. Warning is given because
we break the loop when nextdir == NULL and parent was not previously set.
(it should not happen, but compiler does not know that).
zap_add() and zap_fat_write_array_chunk() takes uint8_t *, use type
cast.
zap_fat_write_array_chunk() should check sz for 0 to avoid
use of uninitialized pointer.

pci_iov: Support dynamic subordinate bus growth during VF creation
Certain SR-IOV devices enumerate Virtual Functions (VFs) on a different
PCIe bus than their parent Physical Function (PF). In such cases, the
default subordinate bus range assigned by BIOS may be insufficient to cover
all VFs.
This patch dynamically expands the subordinate bus range by:
- Allocating additional bus numbers using bus_alloc_resource() when VFs are
initialized
- Releasing the reserved bus range during VF deletion via
bus_release_resource()

ssh: Reduce sshd_config diffs against OpenSSH 10.0p2
Upstream had a poor description for KbdInteractiveAuthentication prior
to the 10.0p2 release. We use KbdInteractiveAuthentication for PAM
authentication, and we replaced the poor description with a note about
use by PAM.
In 10.0p2 the upstream description has been fixed. Incorporate that
text now as it is an improvement and avoids a conflict in the upcoming
10.0p2 import.

netinet6: Don't return non-IPv6 enabled interfaces from in6_getlinkifnet()
There are scenarios where we can end up looking up an interface by its scope and
turn up an interface that doesn't have IPv6 enabled on it. If that happens we
could end up dereferencing a NULL pointer accessing ifp->if_afdata[AF_INET6].
Check for this.
One such scenario is if a firewall rewrites a destination address to a
link-local address, with an embedded scope for such an interface. Attach a test
case which provokes this.
