If an if_gif exists and has an address assigned inside a vnet when the
vnet is shut down we failed to clean up the address, leading to a panic
when we ip_destroy() and the V_in_ifaddrhashtbl is not empty.
This happens because of the VNET_SYS(UN)INIT order, which means we
destroy the if_gif interface before the addresses can be purged (and
if_detach() does not remove addresses, it assumes this will be done by
the stack teardown code).
Set subsystem SI_SUB_PSEUDO just like if_bridge so the cleanup
operations happen in the correct order.

AES-CBC OpenSSL assembly is used underneath.
The glue layer(ossl_aes.c) is based on CHACHA20 implementation.
Contrary to the SHA and CHACHA20, AES OpenSSL assembly logic
does not have a fallback implementation in case CPU doesn't
support required instructions.
Because of that CPU caps are checked during initialization and AES
support is advertised only if available.
The feature is available on all architectures that ossl supports:
i386, amd64, arm64.
The biggest advantage of this patch over existing solutions
(aesni(4) and armv8crypto(4)) is that it supports SHA,
allowing for ETA operations.

If a pNFS server's DS runs out of disk space, it replies
NFSERR_NOSPC to the client doing writing. For the Linux
client, it then sends a LayoutError RPC to the server to
tell it about the error and keeps retrying, doing repeated
LayoutGet and Write RPCs to the DS. The Linux client is
"stuck" until disk space on the DS is free'd up.
For a mirrored server configuration, the first mirror that
ran out of space was taken offline. This does not make
much sense, since the other mirror(s) will run out of space
soon and the fix is a manual cleanup up disk space.
This patch changes the pNFS server to not disable a mirror
for the mirrored case when this occurs.
Further work is needed, since the Linux client expects the
MDS to reply NFSERR_NOSPC to LayoutGets once the DS is out
of space. Without this further change, the above mentioned
looping occurs.

When the NFSv4.2 server does a VOP_ALLOCATE(), it needs
the operation to be done for the RPC's credential and not
td_ucred. It also needs the writing to be done synchronously.
This patch adds "ioflag" and "cred" arguments to VOP_ALLOCATE()
and modifies vop_stdallocate() to use these arguments.
The VOP_ALLOCATE.9 man page will be patched separately.

Instead of validating that a vnode belongs to unionfs only when the

Add an assertion to unionfs_node_update() that the upper vnode is
exclusively locked; we already make the same assertion for the lower
vnode.
Also, assert in unionfs_noderem() that the vnode lock is not recursed
and acquire v_lock with LK_NOWAIT. Since v_lock is not the active
lock for the vnode at this point, it should not be contended.
Finally, remove VDIR assertions from unionfs_get_cached_vnode().
lvp/uvp will be referenced but not locked at this point, so v_type
may concurrently change due to vgonel(). The cached unionfs node,
if one exists, would only have made it into the cache if lvp/uvp
were of type VDIR at the time of insertion; the corresponding
VDIR assert in unionfs_ins_cached_vnode() should be safe because
lvp/uvp will be locked by that time and will not be used if either
is doomed.

That didn't work very well with switches.
Fix that by searching through "ports" subnode, checking if any of its

Since switches tend to have multiple ports we also have multiple
candidates.
