making it externally visible. Since other threads cannot observe the

This fixes a -Waddress-of-packed-member warning about a possibly

__packed has to be removed from struct exfat_dirent as well to fix an

struct sglist is intended for holding S/G lists of physical address
ranges, not virtual address ranges. GCC 9.x issues several warnings
due to casts between pointers and integers of different sizes as a
result (vm_paddr_t is 64-bits on i386). Instead, add a local 'struct
hv_sglist' which uses an array of 'struct iovec' to hold the S/G list
of virtual address ranges.

- After a connection has fallen back from NIC TLS to SW TLS, any
pacing rate changes should modify the inpcb send tag even though
SB_TLS_IFNET is set.
- If a connection tries to modify the pacing rate before the send
tag has been converted from plain TLS to TLS + RL, don't fail
the rate request set but let it fall through to setting the rate
on the non-TLS inpcb RL tag.

At the moment this is mostly a no-op but in the future there will be
in-flight encrypted data which requires software decryption. This
same setup is also needed for NIC TLS RX.
Note that this does break TOE TLS RX for AES-CBC ciphers since there
is no software fallback for AES-CBC receive. This will be resolved
one way or another before 14.0 is released.

There are some error paths in ioctl handlers that will call
pf_krule_free() before the rule's rpool.mtx field is initialized,
causing a panic with INVARIANTS enabled.
Fix the problem by introducing pf_krule_alloc() and initializing the
mutex there. This does mean that the rule->krule and pool->kpool
conversion functions need to stop zeroing the input structure, but I
don't see a nicer way to handle this except perhaps by guarding the
mtx_destroy() with a mtx_initialized() check.
Constify some related functions while here and add a regression test
based on a syzkaller reproducer.

According to the RM rings can hold at most ring_size - 1 descriptors at any time.
No additional logic is needed since iflib already respects this constrain.
Thanks to that the pidx == cidx situation is not ambiguous and indicates an
empty ring.
Use that to simplify the logic that calculates the amount of processed frames.

when the vnode is doomed after relock. The mere fact that the vnode is
doomed does not prevent us from doing UFS operations on it while it is
still belongs to UFS, which is determined by non-NULL v_data. Not
finishing some operations, e.g. not syncing the inode block only because
the vnode started reclamation, is not correct.
Add macro IS_UFS() which incapsulates the v_data != NULL, and use it
instead of VN_IS_DOOMED() for places where the operation completion is
important.

The lock is unneccessary since the mount point is busied, which prevents
unmount and syncer vnode deallocation. Having the vnode locked causes
innocent LoRs and complicates debugging.
Also stop starting write accounting around it. Any caller of
VOP_FSYNC() must do it already, and sync_vnode() does.
