- push all bridge logic from if_ethersubr.c into bridge.c
make bridge_in() return mbuf pointer (or NULL).
- call only bridge_in() from ether_input(), after ng_ether_input()
was optinally called.
- call bridge_in() from ng_ether_rcv_upper().

md(8). The former is generally not going to fail, but the latter can
fail when the underlying swap device returns an error.
There are still plenty of other places where vm_pager_get_pages() failing
will lead directly to crashes, so it's a good idea to put your swap on
RAID if you care enough to put any of your disks on RAID....
by the time that kldload(8) returns. Satisfy that by making the GEOM
module load event -- only when the kernel is !cold -- wait until the
GEOM module init function has finished instead of returning immediately.
This is the other half of fixing md(8) (actually, "mfs" in fstab(5))
that is similar to r1.128 of src/sys/dev/md/md.c. This bug would be
why RAM disks would often fail on boot and the first call to mdconfig(8)
would probably fail.
pjd has ideas for not requiring kldload(8) to work synchronously for
control devices that could make this obsolete.

PNP user.
sysctl routines and state. Add some code to use it for signalling the need
to downconvert a data structure to 32 bits on a 64 bit OS when requested by
a 32 bit app.
I tried to do this in a generic abi wrapper that intercepted the sysctl
oid's, or looked up the format string etc, but it was a real can of worms
that turned into a fragile mess before I even got it partially working.
With this, we can now run 'sysctl -a' on a 32 bit sysctl binary and have
it not abort. Things like netstat, ps, etc have a long way to go.
This also fixes a bug in the kern.ps_strings and kern.usrstack hacks.
These do matter very much because they are used by libc_r and other things.
Extract the struct cdev pointer and the tty device from inside rather than
incorrectly casting the 'struct cdev *' pointer to a 'dev_t' int. Not
that this was particularly important since it was only used for reading
vmcore files.

the availablility of the specified netisr. This uncomplete unregister leads
directly to a crash when the KLD unregistering the netisr is unloaded.

Feet shot: Robert Huff <roberthuff at rcn dot com>
Sockets in the listen queues have reference counts of 0, so if the
protocol decides to disconnect the pcb and try to free the socket, this
triggered a race with accept() wherein accept() would bump the reference
count before sofree() had removed the socket from the listen queues,
resulting in a panic in sofree() when it discovered it was freeing a
referenced socket. This might happen if a RST came in prior to accept()
on a TCP connection.
The fix is two-fold: to expand the coverage of the accept mutex earlier
in sofree() to prevent accept() from grabbing the socket after the "is it
really safe to free" tests, and to expand the logic of the "is it really
safe to free" tests to check that the refcount is still 0 (i.e., we
didn't race).
