[patch 01/32] IPV6 NDISC: Calculate packet length correctly for allocation.

[Chris Wright]

From: David Miller <davem@davemloft.net>

MAX_HEADER does not include the ipv6 header length in it,
so we need to add it in explicitly.

[patch 02/32] softmac: remove netif_tx_disable when scanning

------------------

From: Michael Buesch <mb@bu3sch.de>

In the scan section of ieee80211softmac, network transmits are disabled.
When SoftMAC re-enables transmits, it may override the wishes of a driver
that may have very good reasons for disabling transmits. At least one failure
in bcm43xx can be traced to this problem. In addition, several unexplained
problems may arise from the unexpected enabling of transmits.

No need to revisit a chain we'd already finished with during

[patch 07/32] NET_SCHED: policer: restore compatibility with old iproute binaries

[-- Type: text/plain, Size: 2509 bytes --]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Patrick McHardy <kaber@trash.net>

The tc actions increased the size of struct tc_police, which broke
compatibility with old iproute binaries since both the act_police
and the old NET_CLS_POLICE code check for an exact size match.

Since the new members are not even used, the simple fix is to also
accept the size of the old structure. Dumping is not affected since
old userspace will receive a bigger structure, which is handled fine.

dm-crypt needs CBC in the same manner -- normal (via howto) use of 
cryptsetup doesn't work otherwise, same as with cryptoloop.

------------------

From: Len Brown <len.brown@intel.com>

This reverts commit 281ea49b0c294649a6de47a6f8fbe5611137726b,
which broke ACPI Interrupt source overrides that move
the SCI from one IRQ in PIC mode to another in IOAPIC mode.

If the SCI shared an interrupt line with another device,
this would result in a "irq 18: nobody cared" type failure.

[patch 12/32] NETFILTER: Fix {ip, ip6, arp}_tables hook validation

[Chris Wright]

[-- Attachment #1: netfilter-fix-ip-ip6-arp-_tables-hook-validation.patch --]
[-- Type: text/plain, Size: 10294 bytes --]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Dmitry Mishin <dim@openvz.org>

Commit 590bdf7fd2292b47c428111cb1360e312eff207e introduced a regression
in match/target hook validation. mark_source_chains builds a bitmask
for each rule representing the hooks it can be reached from, which is
then used by the matches and targets to make sure they are only called
from valid hooks. The patch moved the match/target specific validation
before the mark_source_chains call, at which point the mask is always zero.

This patch returns back to the old order and moves the standard checks
to mark_source_chains. This allows to get rid of a special case for
standard targets as a nice side-effect.

[patch 13/32] NETFILTER: Fix iptables compat hook validation

[Chris Wright]

[-- Attachment #1: netfilter-fix-iptables-compat-hook-validation.patch --]
[-- Type: text/plain, Size: 4623 bytes --]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Dmitry Mishin <dim@openvz.org>

In compat mode, matches and targets valid hooks checks always successful due
to not initialized e->comefrom field yet. This patch separates this checks from
translation code and moves them after mark_source_chains() call, where these
marks are initialized.

[patch 14/32] NETFILTER: bridge netfilter: deal with martians correctly

[Chris Wright]

[-- Attachment #1: netfilter-bridge-netfilter-deal-with-martians-correctly.patch --]
[-- Type: text/plain, Size: 4594 bytes --]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Bart De Schuymer <bdschuym@pandora.be>

The attached patch resolves an issue where a IP DNATed packet with a
martian source is forwarded while it's better to drop it. It also
resolves messages complaining about ip forwarding being disabled while
it's actually enabled. Thanks to lepton <ytht.net@gmail.com> for
reporting this problem.

This is probably a candidate for the -stable release.

ib_ucm_cleanup_events() holds file_mutex while calling ib_destroy_cm_id().
This can deadlock since ib_destroy_cm_id() flushes event handlers, and
ib_ucm_event_handler() needs file_mutex, too.  Therefore, drop the
file_mutex during the call to ib_destroy_cm_id().

ip_summed changes last summer had missed that one.  As the result,
we have ip_summed interpreted as CHECKSUM_PARTIAL now.  IOW,
->csum is interpreted as offset of checksum in the packet.  net/core/*
will both read and modify the value as that offset, with obvious
reasons.  At the very least it's a remote memory corruptor.

[patch 19/32] XFRM: Use output device disable_xfrm for forwarded packets

[-- Type: text/plain, Size: 1310 bytes --]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Patrick McHardy <kaber@trash.net>

Currently the behaviour of disable_xfrm is inconsistent between
locally generated and forwarded packets. For locally generated
packets disable_xfrm disables the policy lookup if it is set on
the output device, for forwarded traffic however it looks at the
input device. This makes it impossible to disable xfrm on all
devices but a dummy device and use normal routing to direct
traffic to that device.

Always use the output device when checking disable_xfrm.

Really linux/spinlock.h should include linux/interrupt.h.  But interrupt.h
includes sched.h which will need spinlock.h.

So the patch breaks the _bh declarations out into a separate header and

The problem is that data_page pointer can be NULL, so we should skip data

[patch 28/32] autofs: fix error code path in autofs_fill_sb()

[-- Type: text/plain, Size: 4225 bytes --]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Jiri Kosina <jkosina@suse.cz>

When kernel is compiled with old version of autofs (CONFIG_AUTOFS_FS), and
new (observed at least with 5.x.x) automount deamon is started, kernel
correctly reports incompatible version of kernel and userland daemon, but
then screws things up instead of correct handling of the error:

 autofs: kernel does not match daemon version
 =====================================
 [ BUG: bad unlock balance detected! ]
 -------------------------------------
 automount/4199 is trying to release lock (&type->s_umount_key) at:
 [<c0163b9e>] get_sb_nodev+0x76/0xa4
 but there are no more locks to release!

 other info that might help us debug this:
 no locks held by automount/4199.

 Leftover inexact backtrace:
  =======================

and then deadlock comes.

The problem: autofs_fill_super() returns EINVAL to get_sb_nodev(), but
before that, it calls kill_anon_super() to destroy the superblock which
won't be needed.  This is however way too soon to call kill_anon_super(),
because get_sb_nodev() has to perform its own cleanup of the superblock
first (deactivate_super(), etc.).  The correct time to call
kill_anon_super() is in the autofs_kill_sb() callback, which is called by
deactivate_super() at proper time, when the superblock is ready to be
killed.

I can see the same faulty codepath also in autofs4.  This patch solves
issues in both filesystems in a same way - it postpones the
kill_anon_super() until the proper time is signalized by deactivate_super()
calling the kill_sb() callback.

No objections.
I'm sure I tested this case when I did the original patch that has the
error which this patch fixes.

The bug is clearly present and needs fixing.

[patch 29/32] softirq: remove BUG_ONs which can incorrectly trigger

[Chris Wright]

[-- Attachment #1: softirq-remove-bug_ons-which-can-incorrectly-trigger.patch --]
[-- Type: text/plain, Size: 1823 bytes --]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Zachary Amsden <zach@vmware.com>

It is possible to have tasklets get scheduled before softirqd has had a chance
to spawn on all CPUs.  This is totally harmless; after success during action
CPU_UP_PREPARE, action CPU_ONLINE will be called, which immediately wakes
softirqd on the appropriate CPU to process the already pending tasklets.  So
there is no danger of having a missed wakeup for any tasklets that were
already pending.

In particular, i386 is affected by this during startup, and is visible when
using a very large initrd; during the time it takes for the initrd to be
decompressed, a timer IRQ can come in and schedule RCU callbacks.  It is also
possible that resending of a hardware IRQ via a softirq triggers the same bug.

Because of different timing conditions, this shows up in all emulators and
virtual machines tested, including Xen, VMware, Virtual PC, and Qemu.  It is
also possible to trigger on native hardware with a large enough initrd,
although I don't have a reliable case demonstrating that.

[patch 30/32] m32r: make userspace headers platform-independent

[Chris Wright]

[-- Attachment #1: m32r-make-userspace-headers-platform-independent.patch --]
[-- Type: text/plain, Size: 6010 bytes --]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Hirokazu Takata <takata@linux-m32r.org>

The m32r kernel 2.6.18-rc1 or after cause build errors of "unknown isa
configuration" for userspace application programs, such as glibc, gdb, etc.

This is because the recent kernel do not include linux/config.h not to expose
kernel headers for userspace.

To fix the above compile errors, this patch fixes two headers ptrace.h and
sigcontext.h for m32r and makes them platform-independent.

[patch 31/32] x86_64: fix boot hang due to nmi watchdog init code

[Chris Wright]

[-- Attachment #1: x86_64-fix-boot-hang-due-to-nmi-watchdog-init-code.patch --]
[-- Type: text/plain, Size: 1794 bytes --]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Ravikiran G Thirumalai <kiran@scalex86.org>

2.6.19 stopped booting (or booted based on build/config) on our x86_64
systems due to a bug introduced in 2.6.19.  check_nmi_watchdog schedules an
IPI on all cpus to busy wait on a flag, but fails to set the busywait flag
if NMI functionality is disabled.

This causes the secondary cpus to spin in an endless loop, causing the
kernel bootup to hang.

Depending upon the build, the busywait flag got overwritten (stack
variable) and caused the kernel to bootup on certain builds.  Following
patch fixes the bug by setting the busywait flag before returning from
check_nmi_watchdog.

I guess using a stack variable is not good here as the calling function
could potentially return while the busy wait loop is still spinning on the
flag.  I would think this is a good candidate for 2.6.19 stable as well.

[patch 32/32] forcedeth: Disable INTx when enabling MSI in forcedeth

[Chris Wright]

[-- Attachment #1: forcedeth-disable-intx-when-enabling-msi-in-forcedeth.patch --]
[-- Type: text/plain, Size: 2286 bytes --]

-stable review patch.  If anyone has any objections, please let us know.
------------------

From: Daniel Barkalow <barkalow@iabervon.org>

At least some nforce cards continue to send legacy interrupts when MSI
is enabled, and these interrupts are treated as unhandled by the
kernel. This patch disables legacy interrupts explicitly when enabling
MSI mode.

The correct fix is to change the MSI infrastructure to disable legacy
interrupts when enabling MSI, but this is potentially risky if the
device isn't PCI-2.3 or is quirky, so the correct fix is going into
mainline, while patches like this one go into -stable.

Legend has it that it is most correct to disable legacy interrupts
before enabling MSI, but the mainline patch does it in the other
order, and this patch is "obviously" the same as mainline.

The general patch got into mainline last night, and this patch is clearly 
the same as that one, limited to the case of forcedeth (the pci_intx() 
calls are lifted from {enable,disable}_msi_mode to all of the indirect 
callers in forcedeth).

NETLINK: Put {IFA,IFLA}_{RTA,PAYLOAD} macros back for userspace.

GLIBC uses them etc.

They are guarded by ifndef __KERNEL__ so nobody will start
accidently using them in the kernel again, it's just for
userspace.

Sorry about that, I regenerated and made sure I picked up new files.
I've pushed up an rc3 (mirroring is a bit slow).

Would it be possible to make this available as a quilt patchset, like this:

It makes things much easier to review because I can use 'quilt annotate'

Well, that's how we keep it in stable-queue.  For example, there's a quilt series
in k.o/pub/scm/linux/kernel/git/stable/stable-queue/review-2.6.19
Can you pull from that?
