Anil Keshavamurthy c38c8db722 [PATCH] ia64: race flushing icache in COW path
There is a race condition that showed up in a threaded JIT environment.
The situation is that a process with a JIT code page forks, so the page is
marked read-only, then some threads are created in the child.  One of the
threads attempts to add a new code block to the JIT page, so a
copy-on-write fault is taken, and the kernel allocates a new page, copies
the data, installs the new pte, and then calls lazy_mmu_prot_update() to
flush caches to make sure that the icache and dcache are in sync.
Unfortunately, the other thread runs right after the new pte is installed,
but before the caches have been flushed.  It tries to execute some old JIT
code that was already in this page, but it sees some garbage in the i-cache
from the previous users of the new physical page.

Fix: we must make the caches consistent before installing the pte.  This is
an ia64 only fix because lazy_mmu_prot_update() is a no-op on all other
architectures.

__vunmap must not rely on area->nr_pages when picking the release methode
for area->pages.  It may be too small when __vmalloc_area_node failed early
due to lacking memory.  Instead, use a flag in vmstruct to differentiate.

Kirill Korotaev de45921535 [PATCH] struct file leakage
2.6.16 leaks like hell. While testing, I found massive leakage
(reproduced in openvz) in:

*filp
*size-4096

And 1 object leaks in
*size-32
*size-64
*size-128

It is the fix for the first one.  filp leaks in the bowels of namei.c.

Seems, size-4096 is file table leaking in expand_fdtables.

I have no idea what are the rest and why they show only accompanying
another leaks.  Some debugging structs?

Herbert Xu 27b437c8b7 [NET]: Update frag_list in pskb_trim
When pskb_trim has to defer to ___pksb_trim to trim the frag_list part of
the packet, the frag_list is not updated to reflect the trimming.  This
will usually work fine until you hit something that uses the packet length
or tail from the frag_list.

Examples include esp_output and ip_fragment.

Another problem caused by this is that you can end up with a linear packet
with a frag_list attached.

It is possible to get away with this if we audit everything to make sure
that they always consult skb->len before going down onto frag_list.  In
fact we can do the samething for the paged part as well to avoid copying
the data area of the skb.  For now though, let's do the conservative fix
and update frag_list.

Many thanks to Marco Berizzi for helping me to track down this bug.

This 4-year old bug took 3 months to track down.  Marco was very patient
indeed :)
