==== diff-scsi-megaraid-dma64-2006062 ====
<div class="change">
Patch from Vasily:

this patch prevent enable of 64-bit DMA on the Megaraid SATA 150-4 controller
because of it does not support 64-bit DMA.

Bug #52530.
</div>
==== diff-ms-CVE-2006-3626 ====
<div class="change">
Patch prepared by Vasily, based on Linux mainstream patches.

Linux Kernel "proc/base.c" Userspace Interaction Local Privilege Escalation
Vulnerability:

A vulnerability has been identified in Linux Kernel, which could be exploited by
local attackers to obtain elevated privileges. This flaw is due to a race
condition in the "pid_revalidate()" and "tid_fd_revalidate()" [fs/proc/base.c]
functions, which could be exploited by malicious users to execute arbitrary
commands with "root" privileges.

Fixed in 2.6.17.5 and and 2.6.17.6 mainstream kernels.

Bug #65414.
</div>

==== diff-ms-group-complete-signal ====
<div class="change">
Patch from mainstream:<br/>
[PATCH] __group_complete_signal: remove bogus BUG_ON

[PATCH] RCU signal handling<br/>
made this BUG_ON() unsafe. This code runs under ->siglock,
while switch_exec_pids() takes tasklist_lock.

==== diff-ms-exit-signal-fix-20060629 ====
<div class="change">
Patch from Pavel:<br/>
fixed issue triggered by 'RCU signal handling' exploit:<br/>
"Fix of signal_struct->curr_target value after __exit_signal().
When task calls __exit_signal() it moves curr_target pointer
on the next thread. If task isn't changed - this pointer must be
set to NULL. Otherwise race:
<source lang="c">
sys_execve() sys_kill()
... ...
de_thread()
switch_exec_pids()
/* at this point thread and leader
* have shared signal_struct but splitted
* (empty) pids lists
*/
release_task()
sig->curr_target = next_thread(tsk);
/* at this point curr_target is set to
* tsk since it's PID_TYPE_TGID list is
* empty
*/
...
___group_complete_signal()
`- t = p->signal->curr_target
/* t is the task which tries to
* exit on the 1st cpu so its
* memory may already be freed
*/"

==== diff-ms-dethread-wait-race-20060712 ====
<div class="change">
Patch from mainstream, prepared by Pavel:<br/>
fixed issue trigered by 'RCU signal handling' exploit:<br/>
[PATCH] fix do_wait() vs exec() race<br/>

When non-leader thread does exec, de_thread adds old leader to the init's
->children list in EXIT_ZOMBIE state and drops tasklist_lock.

This means that release_task(leader) in de_thread() is racy vs do_wait()
from init task.

I think de_thread() should set old leader's state to EXIT_DEAD instead.
