Subject: [patch 00/27] 2.6.22-stable review

This is the start of the stable review cycle for the 2.6.22.17 release.
There are 27 patches in this series, all will be posted as a response to
this one. If anyone has any issues with these being applied, please let
us know. If anyone is a maintainer of the proper subsystem, and wants
to add a Signed-off-by: line to the patch, please respond with it.

These patches are sent out with a number of different people on the
Cc: line. If you wish to be a reviewer, please email [email protected]
to add your name to the list. If you want to be off the reviewer list,
also email us.

Responses should be made by Feb 5 2008, 00:00:00 UTC. Anything received
after that time might be too late.

Note, I think this is going to be the last .22 release, unless people
send me some patches they think really needs to go in, and then, it will
probably only be one more release. It's time to move on :)

thanks,

the -stable release team

Subject: [patch 01/27] X25: Add missing x25_neigh_put

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

------------------
From: Julia Lawall <[email protected]>

[X25]: Add missing x25_neigh_put

[ Upstream commit: 76975f8a3186dae501584d0155ea410464f62815 ]

The function x25_get_neigh increments a reference count. At the point of
the second goto out, the result of calling x25_get_neigh is only stored in
a local variable, and thus no one outside the function will be able to
decrease the reference count. Thus, x25_neigh_put should be called before
the return in this case.

The problem was found using the following semantic match.

Subject: [patch 02/27] SPARC64: Fix two kernel linear mapping setup bugs.

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

------------------
From: David Miller <[email protected]>

[SPARC64]: Fix two kernel linear mapping setup bugs.

[ Upstream commit: 8f361453d8e9a67c85b2cf9b93c642c2d8fe0462 ]

This was caught and identified by Greg Onufer.

Since we setup the 256M/4M bitmap table after taking over the trap
table, it's possible for some 4M mapping to get loaded in the TLB
beforhand which later will be 256M mappings.

This can cause illegal TLB multiple-match conditions. Fix this by
setting up the bitmap before we take over the trap table.

Next, __flush_tlb_all() was not doing anything on hypervisor
platforms. Fix by adding sun4v_mmu_demap_all() and calling it.

[SPARC64]: Fix memory controller register access when non-SMP.

[ Upstream commit: b332b8bc9c67165eabdfc7d10b4a2e4cc9f937d0 ]

get_cpu() always returns zero on non-SMP builds, but we
really want the physical cpu number in this code in order
to do the right thing.

Based upon a non-SMP kernel boot failure report from Bernd Zeimetz.

From: Herbert Xu <[email protected]>

[IPSEC]: Avoid undefined shift operation when testing algorithm ID

[ Upstream commit: f398035f2dec0a6150833b0bc105057953594edb ]

The aalgos/ealgos fields are only 32 bits wide. However, af_key tries
to test them with the expression 1 << id where id can be as large as
253. This produces different behaviour on different architectures.

The following patch explicitly checks whether ID is greater than 31
and fails the check if that's the case.

We cannot easily extend the mask to be longer than 32 bits due to
exposure to user-space. Besides, this whole interface is obsolete
anyway in favour of the xfrm_user interface which doesn't use this
bit mask in templates (well not within the kernel anyway).

[INET]: Fix netdev renaming and inet address labels

[ Upstream commit: 44344b2a85f03326c7047a8c861b0c625c674839 ]

When re-naming an interface, the previous secondary address
labels get lost e.g.

$> brctl addbr foo
$> ip addr add 192.168.0.1 dev foo
$> ip addr add 192.168.0.2 dev foo label foo:00
$> ip addr show dev foo | grep inet
inet 192.168.0.1/32 scope global foo
inet 192.168.0.2/32 scope global foo:00
$> ip link set foo name bar
$> ip addr show dev bar | grep inet
inet 192.168.0.1/32 scope global bar
inet 192.168.0.2/32 scope global bar:2

Turns out to be a simple thinko in inetdev_changename() - clearly we
want to look at the address label, rather than the device name, for
a suffix to retain.

Al went through the ip_fast_csum callers and found this piece of code
that did not validate the IP header. While root crashing the machine
by sending bogus packets through raw or AF_PACKET sockets isn't that
serious, it is still nice to react gracefully.

This patch ensures that the skb has enough data for an IP header and
that the header length field is valid.

Subject: [patch 17/27] CASSINI: Fix endianness bug.

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

------------------
From: Al Viro <[email protected]>

[ Upstream commit: e5e025401f6e926c1d9dc3f3f2813cf98a2d8708 ]

Here's proposed fix for RX checksum handling in cassini; it affects
little-endian working with half-duplex gigabit, but obviously needs
testing on big-endian too.

The problem is, we need to convert checksum to fixed-endian *before*
correcting for (unstripped) FCS. On big-endian it won't matter
(conversion is no-op), on little-endian it will, but only if FCS is
not stripped by hardware; i.e. in half-duplex gigabit mode when
->crc_size is set.

cassini.c part is that fix, cassini.h one consists of trivial
endianness annotations. With that applied the sucker is endian-clean,
according to sparse.

This reverts changeset fa4f0774d7c6cccb4d1fda76b91dd8eddcb2dd6a
([CASSINI]: dont touch page_count) because it breaks the driver.

The local page counting added by this changeset did not account
for the asynchronous page count changes done by kfree_skb()
and friends.

The change adds extra atomics and on top of it all appears to be
totally unnecessary as well.

Subject: [patch 20/27] ACPICA: fix acpi-cpufreq boot crash due to _PSD return-by-reference

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

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

From: Bob Moore <[email protected]>

patch 152c300d007c70c4a1847dad39ecdaba22e7d457 in mainline.

Changed resolution of named references in packages

Fixed a problem with the Package operator where all named
references were created as object references and left otherwise
unresolved. According to the ACPI specification, a Package can
only contain Data Objects or references to control methods. The
implication is that named references to Data Objects (Integer,
Buffer, String, Package, BufferField, Field) should be resolved
immediately upon package creation. This is the approach taken
with this change. References to all other named objects (Methods,
Devices, Scopes, etc.) are all now properly created as reference objects.

This ensures that the quicklists are drained. Otherwise draining may only
occur when the processor reaches an idle state.

A similar fix to netfilter from Eric Dumazet inspired me to
look around a bit by using some grep/sed stuff as looking for
this kind of bugs seemed easy to automate. This is one of them
I found where it looks like this semicolon is not valid.

Greg, could we get that one added? We are already shipping it as our
users have run into the OOM problem with 2.6.22.16 without this patch.

btw. does this program hang for anyone on 2.6.22 (process in D state) ?

#include <stdio.h>
#include <sched.h>

int main( void )

int cpus = 0;

No, it was because I wanted to keep it going for a while to make my life
easier at work. But now I've moved on to another kernel to base things
off of, and don't care so much about .22 :)

patch 96990a4ae979df9e235d01097d6175759331e88c in mainline.

Quicklists calculates the size of the quicklists based on the number of
free pages. This must be the number of free pages that can be allocated
with GFP_KERNEL. node_page_state() includes the pages in ZONE_HIGHMEM and
ZONE_MOVABLE which may lead the quicklists to become too large causing OOM.
