For TCP DDP, handle_ddp_close() needs to see the pre-FIN rcv_nxt to
determine how much data was placed in the local buffer before the FIN
was received. The changes in d59f1c49e26b broke this by updating
rcv_nxt before calling handle_ddp_close().
Fixes: d59f1c49e26b cxgbe tom: Permit rcv_nxt mismatches on FIN for iSCSI connections on T6.

TOE sockets do not change states (listen vs non-listen) once created,

Move the type and function pointers for operations on existing send
tags (modify, query, next, free) out of 'struct ifnet' and into a new
'struct if_snd_tag_sw'. A pointer to this structure is added to the
generic part of send tags and is initialized by m_snd_tag_init()
(which now accepts a switch structure as a new argument in place of
the type).
Previously, device driver ifnet methods switched on the type to call
type-specific functions. Now, those type-specific functions are saved
in the switch structure and invoked directly. In addition, this more
gracefully permits multiple implementations of the same tag within a
driver. In particular, NIC TLS for future Chelsio adapters will use a
different implementation than the existing NIC TLS support for T6
adapters.

- kern_kcov.c needs to be compiled with -fsanitize=kernel-memory when
KMSAN is configured since it calls into various other subsystems.
- Disable address and memory sanitizers in kcov(4)'s coverage sanitizer
callbacks, as they do not provide useful checking. Moreover, with
KMSAN we may otherwise get false positives since the caller (coverage
sanitizer runtime) is not instrumented.
- Disable KASAN and KMSAN interceptors in subr_coverage.c, as they do
not provide any benefit but do introduce overhead when fuzzing.

By default NFS server reports as scope and owner major the host UUID
value and zero for owner minor. It works good in case of standalone
server. But in case of CARP-based HA cluster failover the values
should remain persistent, otherwise some clients like VMware ESXi
get confused by the change and fail to reconnect automatically.
The patch makes server scope, major owner and minor owner values
configurable via sysctls. If not set (by default) the host UUID
value is still used.

There are two flags to request a non-blocking receive on a socket:
MSG_NBIO and MSG_DONTWAIT. They are handled a bit differently in that
soreceive_generic() and soreceive_stream() will block on the socket I/O
lock when MSG_NBIO is set, but not if MSG_DONTWAIT is set. In general,
MSG_NBIO seems to mean, "don't block if there is no data to receive" and
MSG_DONTWAIT means "don't go to sleep for any reason".
SCTP's soreceive implementation did not allow blocking on the I/O lock
if either flag is set, but this violates an assumption in
aio_process_sb(), which specifies MSG_NBIO but nonetheless
expects to make progress if data is available to read. Change
sctp_sorecvmsg() to block on the I/O lock only if MSG_DONTWAIT
is not set.

When a nvlist(9) is converted into a binary buffer by nvlist_pack(9),
the host endianness is encoded in the nvlist_header of the binary
buffer. The nvlist_unpack(9) function converts a given binary buffer
to an nvlist. In the conversion process the endianness encoded in the
nvlist_header is evaluated and -- should the encoded endianness differ
from the endianess of the decoding host -- endianness conversion is
applied to nvlist_header and nvpair_header elements as well as
to some nvpair values.
In 2015 @oshogbo extended libnv with array support (in 347a39b).
The unpacking code misses the possible need to convert the endianness
of the nvph_nitems element of nvpair_headers.
The patch (re)enables libnv to unpack nvlists regardless of the
endianness of the packing host.
