- Fix a couple of LORs and panics;
- Temporarily remove the code that tries to cleanup sockets that stuck
on accepting queues (both complete and incomplete). I'm taking an ostrich
approach here until I find a better way to deal with sockets that were
disconnected before accepting (i.e. while socket was on complete or
incomplete accept queue).
we can do the stuff we need to do with linux processes at fork and
don't panic the kernel at exit of the child.

LCDs to blink in the V_DISPLAY_ON case, at least in combination with
some 13W3-VGA-adaptors (what's exactly going on is unclear though,
as it happens when all of H-sync, V-sync and video output are enabled
and not touching the sync bits from the preset fixes it). Thus
creator_blank_display() now is reduced to turning the video output
on/off.
Although that DPMS code did what the XFree86/Xorg sunffb(4x) does,
it was questionable in the first place, as both implementations
also turn(ed) off the video output on standby and suspend, thus most
likely causing the monitor to turn off instead of entering standby
or suspend as intended (at least my monitors don't).

copyout(9) instead of copystr(9) for copying the errmsg from
kernel- to user-space. This fixes a panic on sparc64 when
using the nmount(2)-converted mountd(8).
While at it, use bcopy(3) instead of strncpy(3) in the kernel-
to kernel-space case for consistency with vfs_buildopts() and
between kernel- to user-space and kernel- to kernel-space case.
Following issues should be resolved:
- random watchdog timeouts (caused by concurrent phy access)
- some link state issues
- non working TX if media type was set explicitly

conditions. The cause of missing Tx completion interrupts comes from
Tx interrupt moderation mechanism(delayed interrupts) or chipset bug.
If Tx interrupt moderation mechanism is the cause of false watchdog
timeout error we should have to fix all device drivers that have Tx
interrupt moderation capability. We may need more investigation
for this issue. Anyway, the fix is the same for both cases.
This should fix occasional watchdog timeout errors seen on a few
systems.

In fact, there are too many broken BIOS implementations out there and we
cannot fix every possible combination but at least it is consistent with
what we advertise with ioctl(2).

REPORT LUNS command to a device.
camcontrol.[c8]: Implement reportluns. This tries to print the LUNs
out in a reasonable format. Only the periph
addressing method has been tested, since very little
hardware that I know of supports the other methods.
scsi_all.[ch]: Revamp the report luns CDB structure and helper
functions. This constitutes a little bit of an API
change, but since the old CDB length was 10 bytes,
and the REPORT LUNS CDB length is actually 12 bytes,
it's clear that no one was using this API in the
first place.

where table 1 has entries of the form:

This allows trivial implementation of a secondary routing table implemented
in the firewall layer.
I expect more work (under discussion with Glebius) to follow this to clean
up some of the messy parts of ipfw related to tables.

that it operates on lockmgr and sx locks. This can be useful for tracking
down vnode deadlocks in VFS for example. Note that this command is a bit
more fragile than 'show lockchain' as we have to poke around at the
wait channel of a thread to see if it points to either a struct lock or
a condition variable inside of a struct sx. If td_wchan points to
something unmapped, then this command will terminate early due to a fault,
but no harm will be done.

including the pointer to the mutex in question and the tid of the owning
thread.
