actually print the name (or the numeric value, if they can't figure out
the correct name) instead of just returning a pointer to it. Also, since
ioctl numbers are not and probably never will be unique, drop support for
using a switch statement instead of an if/else chain.
relocations are processed, since tls initialization section might be
itself subject for relocations. Only set up of the block is postponed,
the tls block offsets are allocated before relocation processing, since
TLS-related relocations may need offsets ready.

- While at it, rename exphy.c, which comes from NetBSD where the MAC driver
it corresponds to also is named ex(4) instead of xl(4) but that in FreeBSD
actually identifies itself as xlphy(4), and its function names accordingly
for consistency.

The BCM5709 and BCM5716 chips are virtually indistinguishable by

that BCM5709 supports TCP/IP and iSCSI offload in Windows while
the BCM5716 doesn't.

when reaching the zone limit of reassembly queue entries.
When the zone limit was reached not even the missing segment
that would complete the sequence space could be processed
preventing the TCP session forever from making any further
progress.
Solve this deadlock by using a temporary on-stack queue entry
for the missing segment followed by an immediate dequeue again
by delivering the contiguous sequence space to the socket.
Add logging under net.inet.tcp.log_debug for reassembly queue
issues.

On raw sockets the IP header should be delivered as it at came in
from the network except for the byte order swaps in some fields.
This brings us in line with all other OS'es that provide raw

It seems I was under the impression that a tab differs from a single
forward tabulation, namely that it blanks the underlying cells. This
seems not to be the case. They are identical.
This should fix applications like jove(1) that use tabs instead of

As noted in kern/159780, printf() is not very jail-friendly, since it can't be easily monitored by jail management tools. This patch reports an error via log() instead, which, if nobody is watching the log file, still prints to the console.

heading "kernel panics with RPCSEC_GSS" appears to be caused by a
corrupted tailq list for the client structure. Looking at the code, calls
to the function svc_rpc_gss_forget_client() were done in an SMP unsafe
manner, with the svc_rpc_gss_lock only being acquired in the function
and not before it. As such, when multiple threads called
svc_rpc_gss_forget_client() concurrently, it could try and remove the
same client structure from the tailq lists multiple times.
The patch fixes this by moving the critical code into a separate
function called svc_rpc_gss_forget_client_locked(), which must be
called with the lock held. For the one case where the caller would
have no interest in the lock, svc_rpc_gss_forget_client() was retained,
but a loop was added to check that the client structure is still in
the tailq lists before removing it, to make it safe for multiple
concurrent calls.
