Prior to this change, the CRN (Command Reference Number) is reset on any
firmware LIP, LOOP DOWN, or LOOP RESET event in violation of FCP-4 which
specifies that the CRN should only be reset in response to a LIP Reset
(LIPyx) primitive. FCP-4 also indicates PLOGI/LOGO and PRLI/PRLO ELS
actions as conditions for resetting the CRN for the associated initiator
port.
These violations manifest themselves when the HBA is removed from the
loop, or a target device is removed (especially during an outstanding
command) without power cycling. If the HBA and and the target device
determine upon re-establishing the loop that no PLOGI or PRLI is
required, and the target does not issue a LIPxy to the initiator, the
CRN for the target will have been improperly reset by the isp driver. As
a result, the target port will silently ignore all FCP commands issued
during the device probe (which will time out) preventing the device from
attaching.
This change corrects thie CRN reset behavior in response to loop state
changes, also introduces CRN resets for the above mentioned ELS actions
as encountered through async PDB change events.
This change also adds cleanup of outstanding commands in isp_loop_dead()
that was previously missing.

checks to handle false LOOP RESET actions that do not have a
proper associated LIP primitive, and log the primitive in the
debug messages
In isp_async(), remove the goto from ISP_ASYNC_DEV_STAYED, and
only reset the CRN in the DEV_CHANGED action
In isp_async(), when processing an ISPASYNC_CHANGE_PDB status,
reset CRN(s) for the associated nphdl (or all ports) if the
change reason is some form of ELS login/logout. Also remove

wlanwds monitors the physical interface for DWDS requests from VAPs,
but the clone is created against the physical interface. So, if you
have a secondary VAP setup (with a separate, non-physical-default MAC
address) which is configured for DWDS, the temporary DWDS VAPs created
will have the MAC of the parent physical interface and NOT the
actual cloned interface + MAC.
This .. stumped me for a few minutes.
Maybe I'll fix it. Maybe I won't. At least I now have DWDS+encryption
working at home.
Tested:
* yes, with DWDS 11n repeaters now working on freebsd.
During gmirror startup, if component mirrors are found to be dirty as is
typical after a system crash, the mirrors are synchronized to the mirror
with highest priority. However if a gmirror starts without all of its
mirrors present, for example because of some transient delays during
tasting, the remaining mirrors must be synchronized before they may become
active.

When passed the invalid regular expression "a**", the error is
eventually detected and seterr() is called. It sets p->error
appropriatly and p->next and p->end to nuls which is a never used char
nuls[10] which is zeros due to .bss initialization. Unfortunatly,
p_ere_exp() and p_simp_re() both have fall through cases where they set
the error, decrement p->next and access it which means a read from what
ever .bss variable comes before nuls.

-w flag matching with an empty pattern was generally 'broken', allowing
matches to occur on any line whether or not it actually matches -w
criteria.
This fix required a good amount of refactoring to address. procline()
is altered to *only* process the line and return whether it was a match
or not, necessary to be able to short-circuit the whole function in case
of this matchall flag. -m flag handling is moved out as well because it
suffers from the same fate as context handling if we bypass any actual
pattern matching.
The matching context (matches, mostly) didn't previously exist outside
of procline(), so we go ahead and create context object for file
processing bits to pass around. grep_printline() was created due to
this, for the scenarios where the matches don't actually matter and we
just want to print a line or two, a la flushing the context queue and
no -o or --color specified.
Damage from this broken behavior would have been mitigated by the fact
that it is unlikely users would invoke grep -w with an empty pattern.
This was identified while checking PR 105221 for problems it this may
cause in BSD grep, but PR 105221 is *not* a report of this behavior.

Before this change if_lagg was using nonsleepable rmlocks to protect its
internal state. This patch introduces another sx lock to protect code
paths that require sleeping, while still uses old rmlock to protect hot
nonsleepable data paths.
This change allows to remove taskqueue decoupling used before to change
interface addresses without holding the lock. Instead it uses sx lock to
protect direct if_ioctl() calls.
As another bonus, the new code synchronizes enabled capabilities of member
interfaces, and allows to control them with ifconfig laggX, that was
impossible before. This part should fix interoperation with if_bridge,
that may need to disable some capabilities, such as TXCSUM or LRO, to allow
bridging with noncapable interfaces.

Any non-0 exit value is acceptable, depending on how the installed grep
interprets the expression. GNU grep interprets it as non-matching, and
in the future BSD grep will interpret it is an error.
