fac24ad7f0 bridge: Simplify mac address generation
Unconditionally use ether_gen_addr() to generate bridge mac addresses.  This
function is now less likely to generate duplicate mac addresses across jails.
The old hand rolled hostid based code adds no value.

3f8bc99c4c ethersubr: Make the mac address generation more robust
If we create two (vnet) jails and create a bridge interface in each we end up
with the same mac address on both bridge interfaces.
These very often conflicts, resulting in same mac address in both jails.

Mitigate this problem by including the jail name in the mac address.

ae070589d3 Replace all instances of the typedef mbuf_t with "struct mbuf *".
The typedef mbuf_t was used for the Mac OS/X port of the code long ago.
Since this port is no longer used and the use of mbuf_t obscures what
the code does (and is not consistent with style(9)), it is no longer needed.
This patch replaces all instances of mbuf_t with "struct mbuf *", so that
it is no longer used.

This patch should not result in any semantic change.

f953e7317a xen-locore: Silence DWARF2 section warning
Silence the "DWARF2 can only represent one section per compilation unit"
warning in amd64 GENERIC builds by disabling Clang's debuginfo generation for
this assembler file (-g0).  The message is replaced by a warning from
ctfconvert that there is no debuginfo to convert (future work).

The file contains some metadata (several ELF notes) and some code.  The code
does not appear to have anything that debuginfo would aid.

I looked at the generated debuginfo (readelf -w xen-locore.o) prior to this
change, and the metadata that would be disabled are things like associated
between binary offset and code line number (not especially useful with a
disassembler), and label metadata for the entry points (not especially useful
as this is already in the symbol table).

23d5326823 tty: convert tty_lock_assert to tty_assert_locked to hide lock type
A later change, currently being iterated on in D24459, will in-fact change
the lock type to an sx so that TTY drivers can sleep on it if they need to.
Committing this ahead of time to make the review in question a little more
palatable.

tty_lock_assert() is unfortunately still needed for now in two places to
make sure that the tty lock has not been recursed upon, for those scenarios
where it's supplied by the TTY driver and possibly a mutex that is allowed
to recurse.

5326289d93 Don't try to copyout() to a kernel buffer.
The handle_string callback for the ENCIOC_GET_ENCNAME and
ENCIOC_GETENCID ioctls tries to copy the size of the generated string
out to userland.  However, the callback only has access to the kernel
copy of the structure populated by copyin().  The copyout() call
simply overwrites the value in the kernel's copy preventing the
subsequent overflow prevention logic from working.

Fix this by instead doing a copyout() of the updated length in the
caller after the callback returns.

c17dd0e88b tests: kqueue: use a more precise timer for the NOTE_ABSTIME test
Originally noticed while attempting to run the kqueue tests under
qemu-user-static, this apparently just happens sometimes when running in a
jail in general -- the timer will fire off "too early," but it's really just
the result of imprecise measurements (noted by cem).

Kicking this over to NOTE_USECONDS still tests the correct thing while
allowing it to work more consistently; a basic sanity test reveals that we
often end up coming in just less than 200 microseconds after the timer
fired off.

82164bdd76 Add a sanity check for nes_numsecflavor to the NFS server.
Ryan Moeller reported crashes in the NFS server that appear to be
caused by stack corruption in nfsrv_compound(). It appears that
the stack got corrupted just after a NFSv4.1 Lookup that crosses
a server mount point.
Although it is just a "theory" at this point, the most obvious way
the stack could get corrupted would be if nfsvno_checkexp() somehow
acquires an export with a bogus nes_numsecflavor value. This would
cause the copying of the secflavors to run off the end of the array,
which is allocated on the stack below where the corruption occurs.

This sanity check is simple to do and would stop the stack corruption
if the theory is correct. Otherwise, doing the sanity check seems to
be a reasonable safety belt to add to the code.

5d6e356cb0 Avoid calling protocol drain routines more than once per reclamation event.
mb_reclaim() calls the protocol drain routines for each protocol in each
domain. Some protocols exist in more than one domain and share drain
routines. In the case of SCTP, it also uses the same drain routine for
its SOCK_SEQPACKET and SOCK_STREAM entries in the same domain.

On systems with INET, INET6, and SCTP all defined, mb_reclaim() calls
sctp_drain() four times. On systems with INET and INET6 defined,
mb_reclaim() calls tcp_drain() twice. mb_reclaim() is the only in-tree
caller of the pr_drain protocol entry.

Eliminate this duplication by ensuring that each pr_drain routine is only
specified for one protocol entry in one domain.
