[PATCH] uml: fix random segfaults at bootup

Don't use printk() where "current_thread_info()" is crap.

Until when we switch to running on init_stack, current_thread_info() evaluates
to crap. Printk uses "current" at times (in detail, &current is evaluated with
CONFIG_DEBUG_SPINLOCK to check the spinlock owner task).

And this leads to random segmentation faults.

Exactly, what happens is that &current = *(current_thread_info()), i.e. round
down $esp and dereference the value. I.e. access the stack below $esp, which

As reported by Jules Villard <jvillard@ens-lyon.fr> and some others, the

NOTE: RFC 3810 specifies the source list should be saved and each
  source reported individually as an IS_IN. This is an obvious DOS
  path, requiring the host to store and then multicast as many sources
  as are queried (e.g., millions...). This alternative sends a full,
  relevant report that's limited to number of sources present on the
  machine.

4) fix "add_grec()" to send empty-source records when it should
        The original check doesn't account for a non-empty source
        list with all sources inactive; the new code keeps that
        short-circuit case, and also generates the group header
        with an empty list if needed.

5) fix mca_crcount decrement to be after add_grec(), which needs

3 instruction window causing TIF_NEED_RESCHED to be set won't be

Nothing currently prevents gcc from performing that reordering.  There
is already a barrier() before the decrement of the preemption count, but
another one is needed between this and the TIF_NEED_RESCHED flag test

[IPSEC]: Fix policy updates missed by sockets

The problem is that when new policies are inserted, sockets do not see
the update (but all new route lookups do).

This bug is related to the SA insertion stale route issue solved
recently, and this policy visibility problem can be fixed in a similar
way.

The fix is to flush out the bundles of all policies deeper than the
policy being inserted.  Consider beginning state of "outgoing"
direction policy list:

policy A --> policy B --> policy C --> policy D

First, realize that inserting a policy into a list only potentially
changes IPSEC routes for that direction.  Therefore we need not bother
considering the policies for other directions.  We need only consider
the existing policies in the list we are doing the inserting.

Consider new policy "B'", inserted after B.

policy A --> policy B --> policy B' --> policy C --> policy D

Two rules:

1) If policy A or policy B matched before the insertion, they
   appear before B' and thus would still match after inserting
   B'

2) Policy C and D, now "shadowed" and after policy B', potentially
   contain stale routes because policy B' might be selected
   instead of them.

Therefore we only need flush routes assosciated with policies
appearing after a newly inserted policy, if any.

sleep 1
ip addr del 3ffe::2/64 dev eth0

assign ifap = &ifa->if_next, effectively terminating the for-loop.
This prevents us from checking if there are other addresses using the same

When the usb-storage module forces sdev->scsi_level to SCSI_2, it should

layer may attempt to issue SCSI-3 commands to the device, such as REPORT
LUNS, which it cannot handle.  This can prevent the device from working

The AMS Venus DS3 DS2316SU2S SATA-to-SATA+USB enclosure, based on the

correctly on Linux.  The enclosure reports a SCSI-3 SPC-2 command set
level, but does not correctly handle the REPORT LUNS SCSI command -

[PATCH] relayfs: remove warning printk() in relay_switch_subbuf()

There's currently a diagnostic printk in relay_switch_subbuf() meant as
a warning if you accidentally try to log an event larger than the
sub-buffer size.

The problem is if this happens while logging from somewhere it's not
safe to be doing printks, such as in the scheduler, you can end up with
a deadlock.  This patch removes the warning from relay_switch_subbuf()
and instead prints some diagnostic info when the channel is closed.

[PATCH] powerpc: g5 thermal overtemp bug

The g5 thermal control for liquid cooled machines has a small bug, when
the temperatures gets too high, it boosts all fans to the max, but
incorrectly sets the liquids pump to the min instead of the max speed,
thus causing the overtemp condition not to clear and the machine to shut
down after a while. This fixes it to set the pumps to max speed instead.
This problem might explain some of the reports of random shutdowns that
some g5 users have been reporting in the past.

Many thanks to Marcus Rothe for spending a lot of time trying various
patches & sending log logs before I found out that typo. Note that
overtemp handling is still not perfect and the machine might still
shutdown, that patch should reduce if not eliminate such occcurences in
"normal" conditions with high load. I'll implement a better handling
