[PATCH] prevent bad forwarding table updates
Avoid poisoning of the bridge forwarding table by frames that have been
dropped by filtering. This prevents spoofed source addresses on hostile
side of bridge from causing packet leakage, a small but possible security
risk.

Fix possible false assertion failure in log_do_checkpoint(). We might fail
to detect that we actually made a progress when cleaning up the checkpoint
lists if we don't retry after writing something to disk. The patch was
confirmed to fix observed assertion failures for several users.
When we flushed some buffers we need to retry scanning the list.
Otherwise we can fail to detect our progress.

[PATCH] Fix for bttv driver (v0.9.15) for Leadtek WinFast VC100 XP capture cards
Cc: <email address hidden>
This is a tiny patch that fixes bttv-cards.c so that Leadtek WinFast
VC100 XP video capture cards work. I've been advised to post it here
after having already posted it to the v4l mailing list.
This avoids a race that breaks SMP bootup on some machines.
The race is not fully plugged (that is only done with much
more changes in 2.6.12), but should be good enough
for most people.
Keeping the interrupts disabled here is ok because we
don't rely on the timer interrupt for local APIC
timer setup, but always read the timer registers
directly.
[PATCH] Fix deadlock with ip_queue and tcp local input path.
When we have ip_queue being used from LOCAL_IN, then we end up with a
situation where the verdicts coming back from userspace traverse the TCP
input path from syscall context. While this seems to work most of the
time, there's an ugly deadlock:
syscall context is interrupted by the timer interrupt. When the timer
interrupt leaves, the timer softirq get's scheduled and calls
tcp_delack_timer() and alike. They themselves do bh_lock_sock(sk),
which is already held from somewhere else -> boom.
I've now tested the suggested solution by Patrick McHardy and Herbert Xu to
simply use local_bh_{en,dis}able().

[PATCH] try_to_unmap_cluster() passes out-of-bounds pte to pte_unmap()
It may take a little staring to notice, but pte can actually fall off the
end of the pte page in this iteration, which makes life difficult for
kmap_atomic() and the users not expecting it to BUG(). Of course, we're
somewhat lucky in that arithmetic elsewhere in the function guarantees that
at least one iteration is made, lest this force larger rearrangements to be
made. This issue and patch also apply to non-mm mainline and with trivial
adjustments, at least two related kernels.
Discovered during internal testing at Oracle.
