Patches

diff-ms-files-fix-20060329

Patch from Dmitry Mishin <dim@openvz.org>:
Fixed error path of dup_fd()

diff-ms-files-race-fix-20060329

Patch from Pavel Emelianov <xemul@openvz.org>:
Fixed race on put_files_struct on exec with proc.

Restoring files on current on error path may lead to proc holds pointer on already kfree-d files_struct.

diff-ubc-follow-page-k-20060321

Patch from Pavel Emelianov <xemul@openvz.org>:

Remove FOLL_KERN flag form follow_page. It was used by vmalloc_ub only and vmalloc_to_page is enough for it.

diff-ubc-kmem-objuse-20060329

Patch from Pavel Emelianov <xemul@openvz.org>:

Issue found by Alexey Kuznetsov (alexey@openvz.org).

In 2.6.16 some wrong numbers are counted in kmemsize. The code makes some efforts to calculate right number (objuse), but does not use the result. Instead it uses allocated size (obj_size), which is less than even the number shown in /proc/slabinfo (buffer_size).

diff-ubc-net-skb-orphan-unch-20060401

Patch from Alexey Kuznetsov <alexey@openvz.org>:
Fix leakage in UBC on datagram sockets

diff-ubc-thread-info-20060329

Patch from Alexey Kuznetsov <alexey@openvz.org>:
Kernel stacks are not accounted in ubc

diff-ve-compile-20060323

Patch from Dmitry Mishin <dim@openvz.org>:
Fixed compilation with CONFIG_VE_CALLS=y and CONFIG_PROC_FS=n.

Issue found by Benedict (chubby):

diff-ve-file-owner-leak-20060329

Patch from Alexey Kuznetsov <alexey@openvz.org>:
When numfiles ubc overflows, ve_struct leaks

diff-ve-net-conntrack-oops-fix-20060331

Patch from Dmitry Mishin <dim@openvz.org>:
Fix of oops in __ip_conntrack_find.

VPS could issue SO_GET_ORIG_DST get sockopt while they have no ip_conntracks enabled. This leads to oops. Added check to return -ENOPROTOOPT for such case.

diff-ve-net-ipv6-loopback-20060320

Patch from Dmitry Mishin <dim@openvz.org>:

Fixed compilation with CONFIG_IPV6 on, which was broken due to loopback_dev virtualization.

diff-ve-net-netfilter-ip-ct-enable-warn-20060327

Patch from Dmitry Mishin <dim@openvz.org>:
Added warn message for obsoleted ip_conntrack_enable_ve0 param.

diff-ve-net-netfilter-ub-200060330

Patch from Dmitry Mishin <dim@openvz.org>:
x_tables should use mem_ub() function instead of vmalloc_ub()

diff-ve-net-nf-unconfirmed-20060331

Patch from Dmitry Mishin <dim@openvz.org>: Virtualize 'unconfirmed' conntracks' list and thus fix soft lockup on conntracks cleanup.
