On 4-way SMP, about one reboot in twenty hangs while killing processes:
exit needs exclusive tasklist_lock, but something still holds read_lock.
do_signal_stop race case misses unlock, and fixing it fixes the symptom.

As it is ipt_REJECT doesn't work at all with IPsec.  Despite my efforts
previously in making the policy lookups work there I neglected to change
the final call to dst_output so the policy lookup is useless.

ipt_REJECT also had a number of deviations from icmp_send which seems to
be unjustified.  For examples it ignored source routing IP options.

There was a bug in icmp_send too :) It didn't set the ICMP type/code
values for the policy lookup.

TCP options are not guaranteed to be aligned at all, so we should use
get_unaligned when accessing u16- or u32-values in the TCP
options header to avoid alignment errors on some platforms. The patch
applies to vanilla 2.6.11.

This patch is wrong.  This is the *one* place where we do need to
use the path MTU.  The reason is that when the packet is fragmented
we only pay for the IPsec overhead once over all and not once for
each fragment.

Please revert it for now.

The trailer_len in ip_append_data is not quite right as the trailer's
length depends on the length of the entire packet.  However, it should
be harmless since ESP knows how to extend the packet when necessary.

The sal_console and sal_console_uart structures have a circular
relationship since they both initialize member fields to pointers of one
another.  The current code forward declares sal_console_uart as extern so
that sal_console can take its address, but gcc4 complains about this since
the real definition of sal_console_uart is marked 'static'.  This patch
just removes the static qualifier from sal_console_uart to avoid the
inconsistency.
