[000/143] 2.6.32.40-longterm review

[Greg KH]

This is the start of the longterm review cycle for the 2.6.32.40 release.
There are 143 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.

Many thanks to Ben Hutchings for sending the large majority of these
patches to me for inclusion based on the patches in the Debian stable
kernel.  I really appreciate it.

Responses should be made by Sunday, May 8, 2011, 00:01:00 UTC.
Anything received after that time might be too late.

The whole patch series can be found in one patch at:
	kernel.org/pub/linux/kernel/v2.6/longterm-review/patch-2.6.32.40-rc1.gz
and the diffstat can be found below.

thanks,

greg k-h

[001/143] ath: add missing regdomain pair 0x5c mapping

[Greg KH]

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

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

From: Christian Lamparter <chunkeey@googlemail.com>

commit bd39a274fb7b43374c797bafdb7f506598f36f77 upstream.

Joe Culler reported a problem with his AR9170 device:

> ath: EEPROM regdomain: 0x5c
> ath: EEPROM indicates we should expect a direct regpair map
> ath: invalid regulatory domain/country code 0x5c
> ath: Invalid EEPROM contents

It turned out that the regdomain 'APL7_FCCA' was not mapped yet.
According to Luis R. Rodriguez [Atheros' engineer] APL7 maps to
FCC_CTL and FCCA maps to FCC_CTL as well, so the attached patch
should be correct.

[Greg KH]

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

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

From: Liu Yuan <tailai.ly@taobao.com>

commit ed5302d3c25006a9edc7a7fbea97a30483f89ef7 upstream.

We do not call blk_trace_remove_sysfs() in err return path
if kobject_add() fails. This path fixes it.

[003/143] p54: Initialize extra_len in p54_tx_80211

[Greg KH]

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

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

From: Jason Conti <jason.conti@gmail.com>

commit a6756da9eace8b4af73e9dea43f1fc2889224c94 upstream.

This patch fixes a very serious off-by-one bug in
the driver, which could leave the device in an
unresponsive state.

The problem was that the extra_len variable [used to
reserve extra scratch buffer space for the firmware]
was left uninitialized. Because p54_assign_address
later needs the value to reserve additional space,
the resulting frame could be to big for the small
device's memory window and everything would
immediately come to a grinding halt.

[004/143] intel-iommu: Unlink domain from iommu

[Greg KH]

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

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

From: Alex Williamson <alex.williamson@redhat.com>

commit a97590e56d0d58e1dd262353f7cbd84e81d8e600 upstream.

When we remove a device, we unlink the iommu from the domain, but
we never do the reverse unlinking of the domain from the iommu.
This means that we never clear iommu->domain_ids, eventually leading
to resource exhaustion if we repeatedly bind and unbind a device
to a driver.  Also free empty domains to avoid a resource leak.

[005/143] intel-iommu: Fix get_domain_for_dev() error path

[Greg KH]

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

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

From: Alex Williamson <alex.williamson@redhat.com>

commit 2fe9723df8e45fd247782adea244a5e653c30bf4 upstream.

If we run out of domain_ids and fail iommu_attach_domain(), we
fall into domain_exit() without having setup enough of the
domain structure for this to do anything useful.  In fact, it
typically runs off into the weeds walking the bogus domain->devices
list.  Just free the domain.

[007/143] NFS: nfs_wcc_update_inode() should set nfsi->attr_gencount

[Greg KH]

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

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

From: Trond Myklebust <Trond.Myklebust@netapp.com>

commit 27dc1cd3ad9300f81e1219e5fc305d91d85353f8 upstream.

If the call to nfs_wcc_update_inode() results in an attribute update, we
need to ensure that the inode's attr_gencount gets bumped too, otherwise
we are not protected against races with other GETATTR calls.

commit 5680e94148a86e8c31fdc5cb0ea0d5c6810c05b0 upstream.

If cts changes between reading the level at the cts input (USR1_RTSS)
and acking the irq (USR1_RTSD) the last edge doesn't generate an irq and
uart_handle_cts_change is called with a outdated value for cts.

The race was introduced by commit

[010/143] kconfig: Avoid buffer underrun in choice input

[Greg KH]

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

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

From: Ben Hutchings <ben@decadent.org.uk>

commit 3ba41621156681afcdbcd624e3191cbc65eb94f4 upstream.

Commit 40aee729b350 ('kconfig: fix default value for choice input')
fixed some cases where kconfig would select the wrong option from a
choice with a single valid option and thus enter an infinite loop.

However, this broke the test for user input of the form 'N?', because
when kconfig selects the single valid option the input is zero-length
and the test will read the byte before the input buffer.  If this
happens to contain '?' (as it will in a mips build on Debian unstable
today) then kconfig again enters an infinite loop.

[011/143] UBIFS: fix master node recovery

[Greg KH]

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

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

From: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>

commit 6e0d9fd38b750d678bf9fd07db23582f52fafa55 upstream.

This patch fixes the following symptoms:
1. Unmount UBIFS cleanly.
2. Start mounting UBIFS R/W and have a power cut immediately
3. Start mounting UBIFS R/O, this succeeds
4. Try to re-mount UBIFS R/W - this fails immediately or later on,
   because UBIFS will write the master node to the flash area
   which has been written before.

The analysis of the problem:

1. UBIFS is unmounted cleanly, both copies of the master node are clean.
2. UBIFS is being mounter R/W, starts changing master node copy 1, and
   a power cut happens. The copy N1 becomes corrupted.
3. UBIFS is being mounted R/O. It notices the copy N1 is corrupted and
   reads copy N2. Copy N2 is clean.
4. Because of R/O mode, UBIFS cannot recover copy 1.
5. The mount code (ubifs_mount()) sees that the master node is clean,
   so it decides that no recovery is needed.
6. We are re-mounting R/W. UBIFS believes no recovery is needed and
   starts updating the master node, but copy N1 is still corrupted
   and was not recovered!

Fix this problem by marking the master node as dirty every time we
recover it and we are in R/O mode. This forces further recovery and
the UBIFS cleans-up the corruptions and recovers the copy N1 when
re-mounting R/W later.

commit 26cde9f7e2747b6d254b704594eed87ab959afa5 upstream.

It has been reported that the new UFO software fallback path
fails under certain conditions with NFS.  I tracked the problem
down to the generation of UFO packets that are smaller than the
MTU.  The software fallback path simply discards these packets.

This patch fixes the problem by not generating such packets on
the UFO path.

[017/143] [PARISC] slub: fix panic with DISCONTIGMEM

[Greg KH]

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

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

From: James Bottomley <James.Bottomley@HansenPartnership.com>

commit 4a5fa3590f09999f6db41bc386bce40848fa9f63 upstream.

Slub makes assumptions about page_to_nid() which are violated by
DISCONTIGMEM and !NUMA.  This violation results in a panic because
page_to_nid() can be non-zero for pages in the discontiguous ranges and
this leads to a null return by get_node().  The assertion by the
maintainer is that DISCONTIGMEM should only be allowed when NUMA is also
defined.  However, at least six architectures: alpha, ia64, m32r, m68k,
mips, parisc violate this.  The panic is a regression against slab, so
just mark slub broken in the problem configuration to prevent users
reporting these panics.

[018/143] [PARISC] set memory ranges in N_NORMAL_MEMORY when onlined

[Greg KH]

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

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

From: David Rientjes <rientjes@google.com>

commit d9b41e0b54fd7e164daf1e9c539c1070398aa02e upstream.

When a DISCONTIGMEM memory range is brought online as a NUMA node, it
also needs to have its bet set in N_NORMAL_MEMORY.  This is necessary for
generic kernel code that utilizes N_NORMAL_MEMORY as a subset of N_ONLINE
for memory savings.

These types of hacks can hopefully be removed once DISCONTIGMEM is either
removed or abstracted away from CONFIG_NUMA.

Fixes a panic in the slub code which only initializes structures for
N_NORMAL_MEMORY to save memory:

[019/143] [media] FLEXCOP-PCI: fix __xlate_proc_name-warning for flexcop-pci

[Greg KH]

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

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

From: Patrick Boettcher <pboettcher@kernellabs.com>

commit b934c20de1398d4a82d2ecfeb588a214a910f13f upstream.

This patch fixes the warning about bad names for sys-fs and other kernel-things. The flexcop-pci driver was using '/'-characters in it, which is not good.
This has been fixed in several attempts by several people, but obviously never made it into the kernel.

[020/143] m68k/mm: Set all online nodes in N_NORMAL_MEMORY

[Greg KH]

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

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

From: Michael Schmitz <schmitzmic@googlemail.com>

commit 4aac0b4815ba592052758f4b468f253d383dc9d6 upstream.

For m68k, N_NORMAL_MEMORY represents all nodes that have present memory
since it does not support HIGHMEM.  This patch sets the bit at the time
node_present_pages has been set by free_area_init_node.
At the time the node is brought online, the node state would have to be
done unconditionally since information about present memory has not yet
been recorded.

If N_NORMAL_MEMORY is not accurate, slub may encounter errors since it
uses this nodemask to setup per-cache kmem_cache_node data structures.

This pach is an alternative to the one proposed by David Rientjes
<rientjes@google.com> attempting to set node state immediately when
bringing the node online.

[021/143] nfs: dont lose MS_SYNCHRONOUS on remount of noac mount

[Greg KH]

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

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

From: Jeff Layton <jlayton@redhat.com>

commit 26c4c170731f00008f4317a2888a0a07ac99d90d upstream.

On a remount, the VFS layer will clear the MS_SYNCHRONOUS bit on the
assumption that the flags on the mount syscall will have it set if the
remounted fs is supposed to keep it.

In the case of "noac" though, MS_SYNCHRONOUS is implied. A remount of
such a mount will lose the MS_SYNCHRONOUS flag since "sync" isn't part
of the mount options.

From: Vasiliy Kulikov <segoon@openwall.com>

commit 194b3da873fd334ef183806db751473512af29ce upstream.

pg_start is copied from userspace on AGPIOC_BIND and AGPIOC_UNBIND ioctl
cmds of agp_ioctl() and passed to agpioc_bind_wrap().  As said in the
comment, (pg_start + mem->page_count) may wrap in case of AGPIOC_BIND,
and it is not checked at all in case of AGPIOC_UNBIND.  As a result, user
with sufficient privileges (usually "video" group) may generate either
local DoS or privilege escalation.

[024/143] agp: fix OOM and buffer overflow

[Greg KH]

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

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

From: Vasiliy Kulikov <segoon@openwall.com>

commit b522f02184b413955f3bc952e3776ce41edc6355 upstream.

page_count is copied from userspace.  agp_allocate_memory() tries to
check whether this number is too big, but doesn't take into account the
wrap case.  Also agp_create_user_memory() doesn't check whether
alloc_size is calculated from num_agp_pages variable without overflow.
This may lead to allocation of too small buffer with following buffer
overflow.

Another problem in agp code is not addressed in the patch - kernel memory
exhaustion (AGPIOC_RESERVE and AGPIOC_ALLOCATE ioctls).  It is not checked
whether requested pid is a pid of the caller (no check in agpioc_reserve_wrap()).
Each allocation is limited to 16KB, though, there is no per-process limit.
This might lead to OOM situation, which is not even solved in case of the
caller death by OOM killer - the memory is allocated for another (faked) process.

[025/143] Input: xen-kbdfront - fix mouse getting stuck after save/restore

[Greg KH]

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

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

From: Igor Mammedov <imammedo@redhat.com>

commit c36b58e8a9112017c2bcc322cc98e71241814303 upstream.

Mouse gets "stuck" after restore of PV guest but buttons are in working
condition.

If driver has been configured for ABS coordinates at start it will get
XENKBD_TYPE_POS events and then suddenly after restore it'll start getting
XENKBD_TYPE_MOTION events, that will be dropped later and they won't get
into user-space.

Regression was introduced by hunk 5 and 6 of
5ea5254aa0ad269cfbd2875c973ef25ab5b5e9db
("Input: xen-kbdfront - advertise either absolute or relative
coordinates").

Driver on restore should ask xen for request-abs-pointer again if it is
available. So restore parts that did it before 5ea5254.

[026/143] [SCSI] pmcraid: reject negative request size

[Greg KH]

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

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

From: Dan Rosenberg <drosenberg@vsecurity.com>

commit 5f6279da3760ce48f478f2856aacebe0c59a39f3 upstream.

There's a code path in pmcraid that can be reached via device ioctl that
causes all sorts of ugliness, including heap corruption or triggering
the OOM killer due to consecutive allocation of large numbers of pages.
Not especially relevant from a security perspective, since users must
have CAP_SYS_ADMIN to open the character device.

First, the user can call pmcraid_chr_ioctl() with a type
PMCRAID_PASSTHROUGH_IOCTL.  A pmcraid_passthrough_ioctl_buffer
is copied in, and the request_size variable is set to
buffer->ioarcb.data_transfer_length, which is an arbitrary 32-bit signed
value provided by the user.

If a negative value is provided here, bad things can happen.  For
example, pmcraid_build_passthrough_ioadls() is called with this
request_size, which immediately calls pmcraid_alloc_sglist() with a
negative size.  The resulting math on allocating a scatter list can
result in an overflow in the kzalloc() call (if num_elem is 0, the
sglist will be smaller than expected), or if num_elem is unexpectedly
large the subsequent loop will call alloc_pages() repeatedly, a high
number of pages will be allocated and the OOM killer might be invoked.

Prevent this value from being negative in pmcraid_ioctl_passthrough().

[Greg KH]

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

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

From: Dan Rosenberg <drosenberg@vsecurity.com>

commit a1f74ae82d133ebb2aabb19d181944b4e83e9960 upstream.

At two points in handling device ioctls via /dev/mpt2ctl, user-supplied
length values are used to copy data from userspace into heap buffers
without bounds checking, allowing controllable heap corruption and
subsequently privilege escalation.

Additionally, user-supplied values are used to determine the size of a
copy_to_user() as well as the offset into the buffer to be read, with no
bounds checking, allowing users to read arbitrary kernel memory.

[028/143] [SCSI] put stricter guards on queue dead checks

[Greg KH]

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

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

From: James Bottomley <James.Bottomley@suse.de>

commit 86cbfb5607d4b81b1a993ff689bbd2addd5d3a9b upstream.

SCSI uses request_queue->queuedata == NULL as a signal that the queue
is dying.  We set this state in the sdev release function.  However,
this allows a small window where we release the last reference but
haven't quite got to this stage yet and so something will try to take
a reference in scsi_request_fn and oops.  It's very rare, but we had a
report here, so we're pushing this as a bug fix

The actual fix is to set request_queue->queuedata to NULL in
scsi_remove_device() before we drop the reference.  This causes
correct automatic rejects from scsi_request_fn as people who hold
additional references try to submit work and prevents anything from
getting a new reference to the sdev that way.

[029/143] mmc: sdhci-pci: Fix error case in sdhci_pci_probe_slot()

[Greg KH]

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

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

From: Chris Ball <cjb@laptop.org>

commit 9fdcdbb0d84922e7ccda2f717a04ea62629f7e18 upstream.

If pci_ioremap_bar() fails during probe, we "goto release;" and free the
host, but then we return 0 -- which tells sdhci_pci_probe() that the probe
succeeded.  Since we think the probe succeeded, when we unload sdhci we'll
go to sdhci_pci_remove_slot() and it will try to dereference slot->host,
which is now NULL because we freed it in the error path earlier.

The patch simply sets ret appropriately, so that sdhci_pci_probe() will
detect the failure immediately and bail out.

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

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

From: Alan Stern <stern@rowland.harvard.edu>

commit cee6a262550f53a13acfefbc1e3e5ff35c96182c upstream.

This patch (as1460) fixes a regression in the usbip driver caused by
the new check for Transaction Translators in USB-2 hubs.  The root hub
registered by vhci_hcd needs to have the has_tt flag set, because it
can connect to low- and full-speed devices as well as high-speed
devices.

[033/143] x86, AMD: Fix APIC timer erratum 400 affecting K8 Rev.A-E processors

[Greg KH]

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

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

From: Boris Ostrovsky <ostr@amd64.org>

commit e20a2d205c05cef6b5783df339a7d54adeb50962 upstream.

Older AMD K8 processors (Revisions A-E) are affected by erratum
400 (APIC timer interrupts don't occur in C states greater than
C1). This, for example, means that X86_FEATURE_ARAT flag should
not be set for these parts.

This addresses regression introduced by commit
b87cf80af3ba4b4c008b4face3c68d604e1715c6 ("x86, AMD: Set ARAT
feature on AMD processors") where the system may become
unresponsive until external interrupt (such as keyboard input)
occurs. This results, for example, in time not being reported
correctly, lack of progress on the system and other lockups.

commit a05d2ad1c1f391c7f514a1d1e09b5417968a7d07 upstream.

This fixes the following oops discovered by Dan Aloni:

The bug was that unix domain sockets use a pseduo packet for
connecting and accept uses that psudo packet to get the socket.
In the buggy seqpacket case we were allowing unconnected
sockets to call recvmsg and try to receive the pseudo packet.

That is always wrong and as of commit 7361c36c5 the pseudo
packet had become enough different from a normal packet
that the kernel started oopsing.

Do for seqpacket_recv what was done for seqpacket_send in 2.5
and only allow it on connected seqpacket sockets.

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

From: Dan Rosenberg <drosenberg@vsecurity.com>

commit 0f22072ab50cac7983f9660d33974b45184da4f9 upstream.

When CONFIG_OABI_COMPAT is set, the wrapper for semtimedop does not
bound the nsops argument.  A sufficiently large value will cause an
integer overflow in allocation size, followed by copying too much data
into the allocated buffer.  Fix this by restricting nsops to SEMOPM.

[036/143] i8k: Tell gcc that *regs gets clobbered

[Greg KH]

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

From: Jim Bos <jim876@xs4all.nl>

commit 6b4e81db2552bad04100e7d5ddeed7e848f53b48 upstream.

More recent GCC caused the i8k driver to stop working, on Slackware
compiler was upgraded from gcc-4.4.4 to gcc-4.5.1 after which it didn't
work anymore, meaning the driver didn't load or gave total nonsensical
output.

As it turned out the asm(..) statement forgot to mention it modifies the
*regs variable.

[037/143] Fix gcc 4.5.1 miscompiling drivers/char/i8k.c (again)

[Greg KH]

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

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

From: Jim Bos <jim876@xs4all.nl>

commit 22d3243de86bc92d874abb7c5b185d5c47aba323 upstream.

The fix in commit 6b4e81db2552 ("i8k: Tell gcc that *regs gets
clobbered") to work around the gcc miscompiling i8k.c to add "+m
(*regs)" caused register pressure problems and a build failure.

Changing the 'asm' statement to 'asm volatile' instead should prevent
that and works around the gcc bug as well, so we can remove the "+m".

[ Background on the gcc bug: a memory clobber fails to mark the function
  the asm resides in as non-pure (aka "__attribute__((const))"), so if
  the function does nothing else that triggers the non-pure logic, gcc
  will think that that function has no side effects at all. As a result,
  callers will be mis-compiled.

  Adding the "+m" made gcc see that it's not a pure function, and so
  does "asm volatile". The problem was never really the need to mark
  "*regs" as changed, since the memory clobber did that part - the
  problem was just a bug in the gcc "pure" function analysis  - Linus ]

[038/143] Open with O_CREAT flag set fails to open existing files on non writable directories

[Greg KH]

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

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

From: Sachin Prabhu <sprabhu@redhat.com>

commit 1574dff8996ab1ed92c09012f8038b5566fce313 upstream.

An open on a NFS4 share using the O_CREAT flag on an existing file for
which we have permissions to open but contained in a directory with no
write permissions will fail with EACCES.

A tcpdump shows that the client had set the open mode to UNCHECKED which
indicates that the file should be created if it doesn't exist and
encountering an existing flag is not an error. Since in this case the
file exists and can be opened by the user, the NFS server is wrong in
attempting to check create permissions on the parent directory.

The patch adds a conditional statement to check for create permissions
only if the file doesn't exist.

commit c340b1d640001c8c9ecff74f68fd90422ae2448a upstream.

The kernel automatically evaluates partition tables of storage devices.
The code for evaluating LDM partitions (in fs/partitions/ldm.c) contains
a bug that causes a kernel oops on certain corrupted LDM partitions.
A kernel subsystem seems to crash, because, after the oops, the kernel no
longer recognizes newly connected storage devices.

The patch validates the value of vblk_size.

[049/143] Input: Add support of Synaptics Clickpad device

[Greg KH]

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

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

From: Takashi Iwai <tiwai@suse.de>

commit 5f57d67da87332a9a1ba8fa7a33bf0680e1c76e7 upstream.

The new type of touchpads can be detected via a new query command
0x0c. The clickpad flags are in cap[0]:4 and cap[1]:0 bits.

When the device is detected, the driver now reports only the left
button as the supported buttons so that X11 driver can detect that
the device is Clickpad. A Clickpad device gives the button events
only as the middle button. The kernel driver morphs to the left
button. The real handling of Clickpad is done rather in X driver
side.

[050/143] Input: elantech - do not advertise relative events

[Greg KH]

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

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

From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

commit c7a1f3ccfc2f99427f2e1545b3171e98539c3c95 upstream.

Elantech touchpads work in absolute mode and do not generate relative
events so they should not be advertising them.

[Greg KH]

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

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

From: Florian Ragwitz <rafl@debian.org>

commit 225c61aad38b12924b3df5f4ef43150c0d6bae8c upstream.

The check determining whether device should use 4- or 6-byte packets
was trying to compare firmware with 2.48, but was failing on majors
greater than 2. The new check ensures that versions like 4.1 are
checked properly.

[Greg KH]

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

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

From: Florian Ragwitz <rafl@debian.org>

commit f81bc788ff91d4efd4baf88b2c29713838caa8e5 upstream.

Apparently hardware vendors now ship elantech touchpads with different version
magic. This options allows for them to be tested easier with the current driver
in order to add their magic to the whitelist later.

[Greg KH]

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

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

From: Florian Ragwitz <rafl@debian.org>

commit e938fbfd4a7ac829d48b767c4dc365535d5c4f97 upstream.

In older versions of the elantech hardware/firmware those bits always
were unset, so it didn't actually matter, but newer versions seem to
use those high bits for something else, screwing up the coordinates
we report to the input layer for those devices.

Apparently there are Elantech touchpads that report non-zero in the 2nd byte

zero and 3rd byte contains value that is not a valid report rate, we still
assume that signature is valid.

From: Éric Piel <eric.piel@tremplin-utc.net>

commit 7f29f17b57255b6395046805a98bc663ded63fb8 upstream.

According to the Dell/Ubuntu driver, what was previously observed as
"jumpy cursor" corresponds to the hardware sending incorrect data for
the first two reports of a one touch finger. So let's use the same
workaround as in the other driver. Also, detect another firmware
version with the same behaviour, as in the other driver.

[059/143] Staging: rtl8192su: Fix procfs code for interfaces not named wlan0

[Greg KH]

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

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

From: Ben Hutchings <ben@decadent.org.uk>

commit 41a38d9e632f7c9ec5ad8fc627567d97f4302c4a upstream.

The current code creates directories in procfs named after interfaces,
but doesn't handle renaming.  This can result in name collisions and
consequent WARNINGs.  It also means that the interface name cannot
reliably be used to remove the directory - in fact the current code
doesn't even try, and always uses "wlan0"!

Since the name of a proc_dir_entry is embedded in it, use that when
removing it.

Add a netdev notifier to catch interface renaming, and remove and
re-add the directory at this point.

[062/143] USB: retain USB device power/wakeup setting across reconfiguration

[Greg KH]

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

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

From: Dan Streetman <ddstreet@ieee.org>

commit 16985408b5c48585762ec3b9b7bae1dec4ad7437 upstream.

Currently a non-root-hub USB device's wakeup settings are initialized when the
device is set to a configured state using device_init_wakeup(), but this is not
correct as wakeup is split into "capable" (can_wakeup) and "enabled"
(should_wakeup).  The settings should be initialized instead in the device
initialization (usb_new_device) with the "capable" setting disabled and the
"enabled" setting enabled.  The "capable" setting should be set based on the
device being configured or unconfigured, and "enabled" setting set based on
the sysfs power/wakeup control.

This patch retains the sysfs power/wakeup setting of a non-root-hub USB device
over a USB device re-configuration, which can happen (for example) after a
suspend/resume cycle.

[063/143] USB: dont enable remote wakeup by default

[Greg KH]

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

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

From: Alan Stern <stern@rowland.harvard.edu>

commit 7aba8d014341341590ecb64050b7a026642a62eb upstream.

This patch (as1364) avoids enabling remote wakeup by default on all
non-root-hub USB devices.  Individual drivers or userspace will have
to enable it wherever it is needed, such as for keyboards or network
interfaces.  Note: This affects only system sleep, not autosuspend.

External hubs will continue to relay wakeup requests received from
downstream through their upstream port, even when remote wakeup is not
enabled for the hub itself.  Disabling remote wakeup on a hub merely
prevents it from generating wakeup requests in response to connect,
disconnect, and overcurrent events.

[065/143] GFS2: Clean up gfs2_adjust_quota() and do_glock()

[Greg KH]

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

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

From: Steven Whitehouse <swhiteho@redhat.com>

commit 1e72c0f7c40e665d2ed40014750fdd2fa9968bcf upstream.

Both of these functions contained confusing and in one case
duplicate code. This patch adds a new check in do_glock()
so that we report -ENOENT if we are asked to sync a quota
entry which doesn't exist. Due to the previous patch this is
now reported correctly to userspace.

Also there are a few new comments, and I hope that the code
is easier to understand now.

[066/143] GFS2: Fix writing to non-page aligned gfs2_quota structures

[Greg KH]

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

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

From: Abhijith Das <adas@redhat.com>

commit 7e619bc3e6252dc746f64ac3b486e784822e9533 upstream.

This is the upstream fix for this bug. This patch differs
from the RHEL5 fix (Red Hat bz #555754) which simply writes to the 8-byte
value field of the quota. In upstream quota code, we're
required to write the entire quota (88 bytes) which can be split
across a page boundary. We check for such quotas, and read/write
the two parts from/to the corresponding pages holding these parts.

With this patch, I don't see the bug anymore using the reproducer
in Red Hat bz 555754. I successfully ran a couple of simple tests/mounts/
umounts and it doesn't seem like this patch breaks anything else.

[067/143] GFS2: BUG in gfs2_adjust_quota

[Greg KH]

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

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

From: Abhijith Das <adas@redhat.com>

commit 8b4216018bdbfbb1b76150d202b15ee68c38e991 upstream.

HighMem pages on i686 do not get mapped to the buffer_heads and this was
causing a NULL pointer dereference when we were trying to memset page buffers
to zero.
We now use zero_user() that kmaps the page and directly manipulates page data.
This patch also fixes a boundary condition that was incorrect.

[Greg KH]

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

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

From: Andy Chittenden <andyc.bluearc@gmail.com>

commit 669502ff31d7dba1849aec7ee2450a3c61f57d39 upstream.

When reusing a TCP connection, ensure that it's aborted if a previous
shutdown attempt has been made on that connection so that the RPC over
TCP recovery mechanism succeeds.

[069/143] nfs4: Ensure that ACL pages sent over NFS were not allocated from the slab (v3)

[Greg KH]

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

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

From: Neil Horman <nhorman@tuxdriver.com>

commit e9e3d724e2145f5039b423c290ce2b2c3d8f94bc upstream.

The "bad_page()" page allocator sanity check was reported recently (call
chain as follows):

  bad_page+0x69/0x91
  free_hot_cold_page+0x81/0x144
  skb_release_data+0x5f/0x98

  default_idle+0x0/0x50
  ret_from_intr+0x0/0xa
  default_idle+0x29/0x50
  cpu_idle+0x95/0xb8
  start_kernel+0x220/0x225
  _sinittext+0x22f/0x236

It occurs because an skb with a fraglist was freed from the tcp
retransmit queue when it was acked, but a page on that fraglist had
PG_Slab set (indicating it was allocated from the Slab allocator (which
means the free path above can't safely free it via put_page.

We tracked this back to an nfsv4 setacl operation, in which the nfs code
attempted to fill convert the passed in buffer to an array of pages in
__nfs4_proc_set_acl, which gets used by the skb->frags list in
xs_sendpages.  __nfs4_proc_set_acl just converts each page in the buffer
to a page struct via virt_to_page, but the vfs allocates the buffer via
kmalloc, meaning the PG_slab bit is set.  We can't create a buffer with
kmalloc and free it later in the tcp ack path with put_page, so we need
to either:

1) ensure that when we create the list of pages, no page struct has
   PG_Slab set

 or

2) not use a page list to send this data

Given that these buffers can be multiple pages and arbitrarily sized, I
think (1) is the right way to go.  I've written the below patch to
allocate a page from the buddy allocator directly and copy the data over
to it.  This ensures that we have a put_page free-able page for every
entry that winds up on an skb frag list, so it can be safely freed when
the frame is acked.  We do a put page on each entry after the
rpc_call_sync call so as to drop our own reference count to the page,
leaving only the ref count taken by tcp_sendpages.  This way the data
will be properly freed when the ack comes in

Successfully tested by myself to solve the above oops.

Note, as this is the result of a setacl operation that exceeded a page
of data, I think this amounts to a local DOS triggerable by an
uprivlidged user, so I'm CCing security on this as well.

[071/143] Fix corrupted OSF partition table parsing

[Greg KH]

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

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

From: Timo Warns <Warns@pre-sense.de>

commit 1eafbfeb7bdf59cfe173304c76188f3fd5f1fd05 upstream.

The kernel automatically evaluates partition tables of storage devices.
The code for evaluating OSF partitions contains a bug that leaks data
from kernel heap memory to userspace for certain corrupted OSF
partitions.

In more detail:

  for (i = 0 ; i < le16_to_cpu(label->d_npartitions); i++, partition++) {

iterates from 0 to d_npartitions - 1, where d_npartitions is read from
the partition table without validation and partition is a pointer to an
array of at most 8 d_partitions.

Add the proper and obvious validation.

[072/143] Increase OSF partition limit from 8 to 18

[Greg KH]

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

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

From: Linus Torvalds <torvalds@linux-foundation.org>

commit 34d211a2d5df4984a35b18d8ccacbe1d10abb067 upstream.

It turns out that while a maximum of 8 partitions may be what people
"should" have had, you can actually fit up to 18 entries(*) in a sector.

And some people clearly were taking advantage of that, like Michael
Cree, who had ten partitions on one of his OSF disks.

(*) The OSF partition data starts at byte offset 64 in the first sector,
    and the array of 16-byte partition entries start at offset 148 in
    the on-disk partition structure.

[086/143] virtio_net: Add schedule check to napi_enable call

[Greg KH]

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

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

From: Bruce Rogers <brogers@novell.com>

commit 3e9d08ec0a68f6faf718d5a7e050fe5ca0ba004f upstream.

Under harsh testing conditions, including low memory, the guest would
stop receiving packets. With this patch applied we no longer see any
problems in the driver while performing these tests for extended periods
of time.

Make sure napi is scheduled subsequent to each napi_enable.

[087/143] virtio_net: fix oom handling on tx

[Greg KH]

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

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

From: Rusty Russell <rusty@rustcorp.com.au>

commit 58eba97d0774c69b1cf3e5a8ac74419409d1abbf upstream.

virtio net will never try to overflow the TX ring, so the only reason
add_buf may fail is out of memory. Thus, we can not stop the
device until some request completes - there's no guarantee anything
at all is outstanding.

Make the error message clearer as well: error here does not
indicate queue full.

[088/143] mac80211: Add define for TX headroom reserved by mac80211 itself.

[Greg KH]

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

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

From: Gertjan van Wingerde <gwingerde@gmail.com>

commit d24deb2580823ab0b8425790c6f5d18e2ff749d8 upstream.

Add a definition of the amount of TX headroom reserved by mac80211 itself
for its own purposes. Also add BUILD_BUG_ON to validate the value.
This define can then be used by drivers to request additional TX headroom
in the most efficient manner.

[Greg KH]

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

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

From: Gertjan van Wingerde <gwingerde@gmail.com>

commit e6218cc47bd54710dc523e8c983ceddba625e3ae upstream.

Set the value of extra_tx_headroom in a central place, rather than in each
of the drivers. This is preparatory for taking alignment space into account
in the TX headroom requested by rt2x00.

[090/143] rt2x00: Properly request tx headroom for alignment operations.

[Greg KH]

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

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

From: Gertjan van Wingerde <gwingerde@gmail.com>

commit 7a4a77b7771164d61ce702a588067d1e1d66db7c upstream.

Current rt2x00 drivers may result in a "ieee80211_tx_status: headroom too
small" error message when a frame needs to be properly aligned before
transmitting it.
This is because the space needed to ensure proper alignment isn't
requested from mac80211.
Fix this by adding sufficient amount of alignment space to the amount
of headroom requested for TX frames.

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

From: Pavel Roskin <proski@gnu.org>

commit b59a52f12e483b79e7d32da7ec30dcf3b2e0210b upstream.

Use rt2x00dev->ops->extra_tx_headroom, not rt2x00dev->hw->extra_tx_headroom
in the tx code, as the later may include other headroom not to be used in
the chipset driver.

[095/143] perf tools: Display better error messages on missing packages

[Greg KH]

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

From: Randy Dunlap <randy.dunlap@oracle.com>

commit 1abc7f5500fff8422f34826a006648d8741d83d3 upstream.

Check for libelf headers and glibc headers separately so that
the error message correctly identifies which package
installation is missing/needed.

[096/143] perf tools: Add make DEBUG=1 to remove the -O6 cflag

[Greg KH]

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

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

From: Steven Rostedt <srostedt@redhat.com>

commit 60d526f7fa6246b8e32d5b45610d625a5608d988 upstream.

When using gdb to debug perf, it is practically impossible to
use when perf is compiled with -O6. For developers, this patch
adds the DEBUG feature to the make command line so that a
developer can easily remove the optimization flag.

[097/143] perf tools: Test -fstack-protector-all compiler option for inclusion in CFLAGS

[Greg KH]

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

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

From: Michael Cree <mcree@orcon.net.nz>

commit 5d7bdab75cd56d2bdc0986ae5546be3b09fea70a upstream.

Some architectures (e.g. Alpha) do not support the
-fstack-protector-all compiler option and the use of the option
with -Werror causes the compiler to abort and the build fails.

Test that the compiler supports -fstack-protector-all before
inclusion in CFLAGS.

[098/143] perf tools: Support static build

[Greg KH]

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

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

From: Michael S. Tsirkin <mst@redhat.com>

commit 751386507701010831d72c522171753d2cd903d2 upstream.

This makes it possible to build perf statically, by
performing:

  make LDFLAGS=-static

Since static libraries are only searched in the order they are
specified, move library list from LDFLAGS to EXTLIBS, so that
they are put at the end of linker command line.

[101/143] perf: Use default compiler mode by default

[Greg KH]

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

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

From: Michael S. Tsirkin <mst@redhat.com>

commit 81516c5fc83a13a1d12f466aa7e14f5fd62a63ce upstream.

gcc with no flags typically is a sane default for systems to
use, and looking at the running kernel is probably broken for
cross-builds anyway, so let's not do this.  Add EXTRA_CFLAGS so
that users can override default gcc mode if they want to.

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

From: Arnaldo Carvalho de Melo <acme@redhat.com>

commit 1703f2c321a8a531c393e137a82602e16c6061cb upstream.

At least on Debian PARISC64, using:

acme@parisc:~/git/linux-2.6-tip$ gcc -v
Using built-in specs.
Target: hppa-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Debian
4.3.4-6' --with-bugurl=file:///usr/share/doc/gcc-4.3/README.Bugs
--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr
--enable-shared --enable-multiarch --enable-linker-build-id --with-system-zlib --libexecdir=/usr/lib --without-included-gettext --enable-threads=posix --enable-nls --with-gxx-include-dir=/usr/include/c++/4.3 --program-suffix=-4.3 --enable-clocale=gnu --enable-libstdcxx-debug --enable-objc-gc --enable-mpfr --disable-libssp --enable-checking=release --build=hppa-linux-gnu --host=hppa-linux-gnu --target=hppa-linux-gnu Thread model: posix gcc version 4.3.4 (Debian 4.3.4-6)

there are issues about using 'gcc -o /dev/null':

/usr/bin/ld: final link failed: File truncated
collect2: ld returned 1 exit status

So we test that and use /dev/null in environments where it
works, while using an .INTERMEDIATE file on those where it can't
be used, so that the .perf.dev.null file can be used instead and
then deleted when make exits.

[104/143] perf symbols: allow forcing use of cplus_demangle

[Greg KH]

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

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

From: Kyle McMartin <kyle@mcmartin.ca>

commit d11c7addfe0fa501cb54c824c0fac3481d527433 upstream.

For Fedora, I want to force perf to link against libiberty.a for
cplus_demangle, rather than libbfd.a for bfd_demangle due to licensing insanity
on binutils. (libiberty is LGPL2, libbfd is GPL3.)

If we just rely on autodetection, we'll end up with libbfd linked against us,
since they're both in binutils-static in the buildroot.

[106/143] mmc: fix all hangs related to mmc/sd card insert/removal during suspend/resume

[Greg KH]

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

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

From: Maxim Levitsky <maximlevitsky@gmail.com>

commit 4c2ef25fe0b847d2ae818f74758ddb0be1c27d8e upstream.

If you don't use CONFIG_MMC_UNSAFE_RESUME, as soon as you attempt to
suspend, the card will be removed, therefore this patch doesn't change the
behavior of this option.

However the removal will be done by pm notifier, which runs while
userspace is still not frozen and thus can freely use del_gendisk, without
the risk of deadlock which would happen otherwise.

Card detect workqueue is now disabled while userspace is frozen, Therefore
if you do use CONFIG_MMC_UNSAFE_RESUME, and remove the card during
suspend, the removal will be detected as soon as userspace is unfrozen,
again at the moment it is safe to call del_gendisk.

Tested with and without CONFIG_MMC_UNSAFE_RESUME with suspend and hibernate.

From: Phil Blundell <philb@gnu.org>

commit a27e13d370415add3487949c60810e36069a23a6 upstream.

Don't declare variable sized array of iovecs on the stack since this
could cause stack overflow if msg->msgiovlen is large.  Instead, coalesce
the user-supplied data into a new buffer and use a single iovec for it.

From: Hannes Reinecke <hare@suse.de>

commit 6c71dcb28ff9b63b814a0b76a256f5dae08d3e0d upstream.

This patch fixes the request setup code for mode selects. I got the fixes from
Hannes Reinecke while trying to hunt down some problems and merged it
into one patch. I am sending it because Hannes is busy with other things.

The patch fixes:
- setting of the length for mode selects.
- setting of the data direction for mode select 10.

[117/143] e1000: fix Tx hangs by disabling 64-bit DMA

[Greg KH]

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

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

From: Jesse Brandeburg <jesse.brandeburg@intel.com>

commit e508be174ad36b0cf9b324cd04978c2b13c21502 upstream.

Several users report issues with 32-bit adapters when plugged
into PCI slots in machines with >= 4GB ram.  In particular AMD
systems with HyperTransport to PCI bridges seem to trigger the
issue, but it isn't limited to only them.

This issue is not easily reproducible here, yet still continues
to occur in the field.  For e1000 on PCI devices, just disable DMA
addresses over the 4GB boundary when in PCI (not PCI-X) mode, to
prevent the issue from continuing to pop up.  The performance
impact for this is negligible.

The code was refactored to move the init of the hw struct to its
own function. This allows the init to be called very early in
probe, which then allows using hw-> members for this fix.

A slight refactor to the DMA mask code was done for minor
correctness based on the instructions in DMA-API-HOWTO.

[118/143] btrfs: Require CAP_SYS_ADMIN for filesystem rebalance

[Greg KH]

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

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

From: Ben Hutchings <ben@decadent.org.uk>

commit 6f88a4403def422bd8e276ddf6863d6ac71435d2 upstream.

Filesystem rebalancing (BTRFS_IOC_BALANCE) affects the entire
filesystem and may run uninterruptibly for a long time.  This does not
seem to be something that an unprivileged user should be able to do.

[119/143] af_unix: limit recursion level

[Greg KH]

[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 5164 bytes --]

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

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

From: Eric Dumazet <eric.dumazet@gmail.com>

commit 25888e30319f8896fc656fc68643e6a078263060 upstream.

Its easy to eat all kernel memory and trigger NMI watchdog, using an
exploit program that queues unix sockets on top of others.

lkml ref : http://lkml.org/lkml/2010/11/25/8

This mechanism is used in applications, one choice we have is to have a
recursion limit.

Other limits might be needed as well (if we queue other types of files),
since the passfd mechanism is currently limited by socket receive queue
sizes only.

Add a recursion_level to unix socket, allowing up to 4 levels.

Each time we send an unix socket through sendfd mechanism, we copy its
recursion level (plus one) to receiver. This recursion level is cleared
when socket receive queue is emptied.

[120/143] af_unix: limit unix_tot_inflight

[Greg KH]

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

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

From: Eric Dumazet <eric.dumazet@gmail.com>

commit 9915672d41273f5b77f1b3c29b391ffb7732b84b upstream.

Vegard Nossum found a unix socket OOM was possible, posting an exploit
program.

My analysis is we can eat all LOWMEM memory before unix_gc() being
called from unix_release_sock(). Moreover, the thread blocked in
unix_gc() can consume huge amount of time to perform cleanup because of
huge working set.

One way to handle this is to have a sensible limit on unix_tot_inflight,
tested from wait_for_unix_gc() and to force a call to unix_gc() if this
limit is hit.

This solves the OOM and also reduce overall latencies, and should not
slowdown normal workloads.

[121/143] init, sched: Fix race between init and kthreadd

[Greg KH]

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

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

From: Peter Zijlstra <peterz@infradead.org>

commit b433c3d4549ae74935b585115f076c6fb7bc48fe upstream.

Ilya reported that on a very slow machine he could reliably
reproduce a race between forking init and kthreadd. We first
fork init so that it  obtains pid-1, however since the scheduler
is already fully running at this point it can preempt and run
the init thread before we spawn and set kthreadd_task.

The init thread can then attempt spawning kthreads without
kthreadd being present which results in an OOPS.

Resulted from bonding driver registering packet handlers via dev_add_pack and
then trying to call pskb_may_pull. If another packet handler (like for AF_PACKET
sockets) gets called first, the delivered skb will have a user count > 1, which
causes pskb_may_pull to BUG halt when it does its skb_shared check.  Fix this by
calling skb_share_check prior to the may_pull call sites in the bonding driver
to clone the skb when needed.  Tested by myself and the reported successfully.

[125/143] intel-iommu: Force-disable IOMMU for iGFX on broken Cantiga revisions.

[Greg KH]

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

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

From: David Woodhouse <David.Woodhouse@intel.com>

commit 2d9e667efdfb4e986074d98e7d9a424003c7c43b upstream.

Certain revisions of this chipset appear to be broken. There is a shadow
GTT which mirrors the real GTT but contains pre-translated physical
addresses, for performance reasons. When a GTT update happens, the
translations are done once and the resulting physical addresses written
back to the shadow GTT.

Except sometimes, the physical address is actually written back to the
_real_ GTT, not the shadow GTT. Thus we start to see faults when that
physical address is fed through translation again.

[126/143] ipg: Remove device claimed by dl2k from pci id table

[Greg KH]

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

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

From: Jeff Mahoney <jeffm@suse.com>

commit 25cca5352712561fba97bd37c495593d641c1d39 upstream.

This patch removes D-Link DGE-550T PCI ID (1186:4000) from the ipg
driver. The ipg driver is for IP2000-based cards and the DGE-550T is
a DL2000-based card. The driver loads and works for a few moments, but
once a real workload is applied it stops operating. The ipg driver
claimed this ID since it was introduced in 2.6.24 and it's forced many
users to blacklist it.

The correct driver for this hardware is the dl2k driver, which has been
claiming this PCI ID since the 2.4 days.

[127/143] ipv6: Silence privacy extensions initialization

[Greg KH]

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

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

From: Romain Francoise <romain@orebokech.com>

commit 2fdc1c8093255f9da877d7b9ce3f46c2098377dc upstream.

When a network namespace is created (via CLONE_NEWNET), the loopback
interface is automatically added to the new namespace, triggering a
printk in ipv6_add_dev() if CONFIG_IPV6_PRIVACY is set.

This is problematic for applications which use CLONE_NEWNET as
part of a sandbox, like Chromium's suid sandbox or recent versions of
vsftpd. On a busy machine, it can lead to thousands of useless
"lo: Disabled Privacy Extensions" messages appearing in dmesg.

It's easy enough to check the status of privacy extensions via the
use_tempaddr sysctl, so just removing the printk seems like the most
sensible solution.

[128/143] l2tp: Fix UDP socket reference count bugs in the pppol2tp driver

[Greg KH]

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

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

From: James Chapman <jchapman@katalix.com>

commit c3259c8a7060d480e8eb2166da0a99d6879146b4 upstream.

This patch fixes UDP socket refcnt bugs in the pppol2tp driver.

A bug can cause a kernel stack trace when a tunnel socket is closed.

A way to reproduce the issue is to prepare the UDP socket for L2TP (by
opening a tunnel pppol2tp socket) and then close it before any L2TP
sessions are added to it. The sequence is

Create UDP socket
Create tunnel pppol2tp socket to prepare UDP socket for L2TP
  pppol2tp_connect: session_id=0, peer_session_id=0
L2TP SCCRP control frame received (tunnel_id==0)
  pppol2tp_recv_core: sock_hold()
  pppol2tp_recv_core: sock_put
L2TP ZLB control frame received (tunnel_id=nnn)
  pppol2tp_recv_core: sock_hold()
  pppol2tp_recv_core: sock_put
Close tunnel management socket
  pppol2tp_release: session_id=0, peer_session_id=0
Close UDP socket
  udp_lib_close: BUG

The addition of sock_hold() in pppol2tp_connect() solves the problem.

For data frames, two sock_put() calls were added to plug a refcnt leak
per received data frame. The ref that is grabbed at the top of
pppol2tp_recv_core() must always be released, but this wasn't done for

[Greg KH]

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

From: Ralf Baechle <ralf@linux-mips.org>

commit 3b9c6c11f519718d618f5d7c9508daf78b207f6f upstream.

This only matters for ISA devices with a 24-bit DMA limit or for devices
with a 32-bit DMA limit on systems with ZONE_DMA32 enabled.  The latter
currently only affects 32-bit PCI cards on Sibyte-based systems with more
than 1GB RAM installed.

[130/143] mpt2sas: fix the incorrect scsi_dma_map error checking

[Greg KH]

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

From: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>

commit bb789d01620e5d36081b22edb6fb71cf55ff043c upstream.

scsi_dma_map() returns -1 if an error occurred (zero means that the
command has no data). So the following current code can't catch an
error:

sges_left = scsi_dma_map(scmd);
if (!sges_left) {
	sdev_printk(KERN_ERR, scmd->device, "pci_map_sg"

[131/143] niu: Fix kernel buffer overflow for ETHTOOL_GRXCLSRLALL

[Greg KH]

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

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

From: Ben Hutchings <bhutchings@solarflare.com>

commit ee9c5cfad29c8a13199962614b9b16f1c4137ac9 upstream.

niu_get_ethtool_tcam_all() assumes that its output buffer is the right
size, and warns before returning if it is not.  However, the output
buffer size is under user control and ETHTOOL_GRXCLSRLALL is an
unprivileged ethtool command.  Therefore this is at least a local
denial-of-service vulnerability.

Change it to check before writing each entry and to return an error if
the buffer is already full.

Compile-tested only.

[134/143] rt2500usb: fallback to SW encryption for TKIP+AES

[Greg KH]

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

From: Ondrej Zary <linux@rainbow-software.org>

commit 75f64dd54a185150ebfc45e99351c890d4a2252f upstream.

HW crypto in rt2500usb does not seem to support keys with different ciphers,
which breaks TKIP+AES mode. Fall back to software encryption to fix it.

This should fix long-standing problems with rt2500usb and WPA, such as:
http://rt2x00.serialmonkey.com/phpBB/viewtopic.php?f=4&t=4834
https://bugzilla.redhat.com/show_bug.cgi?id=484888

Also tested that it does not break WEP, TKIP-only and AES-only modes.

[135/143] sata_via: Delay on vt6420 when starting ATAPI DMA write

[Greg KH]

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

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

From: Bart Hartgers <bart.hartgers@gmail.com>

commit a55ab496ea9c820b7192c15ef1fbf3291edfe638 upstream.

When writing a disc on certain lite-on dvd-writers (also rebadged
as optiarc/LG/...) connected to a vt6420, the ATAPI CDB ends
up in the datastream and on the disc, causing silent corruption.
Delaying between sending the CDB and starting DMA seems to
prevent this.

I do not know if there are burners that do not suffer from
this, but the patch should be safe for those as well.

There are many reports of this issue, but AFAICT no solution was
found before. For example:

[138/143] libata: set queue DMA alignment to sector size for ATAPI too

[Greg KH]

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

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

From: Tejun Heo <htejun@gmail.com>

commit 729a6a300e628a48cf12bac93a964a535e83cd1d upstream.

ata_pio_sectors() expects buffer for each sector to be contained in a
single page; otherwise, it ends up overrunning the first page.  This
is achieved by setting queue DMA alignment.  If sector_size is smaller
than PAGE_SIZE and all buffers are sector_size aligned, buffer for
each sector is always contained in a single page.

This wasn't applied to ATAPI devices but IDENTIFY_PACKET is executed
as ATA_PROT_PIO and thus uses ata_pio_sectors().  Newer versions of
udev issue IDENTIFY_PACKET with unaligned buffer triggering the
problem and causing oops.

This patch fixes the problem by setting sdev->sector_size to
ATA_SECT_SIZE on ATATPI devices and always setting DMA alignment to
sector_size.  While at it, add a warning for the unlikely but still
possible scenario where sector_size is larger than PAGE_SIZE, in which
case the alignment wouldn't be enough.

[139/143] usb: musb: core: set has_tt flag

[Greg KH]

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

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

From: Felipe Balbi <balbi@ti.com>

commit ec95d35a6bd0047f05fe8a21e6c52f8bb418da55 upstream.

MUSB is a non-standard host implementation which
can handle all speeds with the same core. We need
to set has_tt flag after commit
d199c96d41d80a567493e12b8e96ea056a1350c1 (USB: prevent
buggy hubs from crashing the USB stack) in order for
MUSB HCD to continue working.

Date:   Fri Feb 19 15:47:33 2010 -0800

    iwlwifi: sanity check before counting number of tfds can be free

we use skb->data after calling ieee80211_tx_status_irqsafe(), which
could free skb instantly.

On current kernels I do not observe practical problems related with
bug, but on 2.6.35.y it cause random system hangs when stressing
wireless link.

From: Zachary Amsden <zamsden@redhat.com>

(cherry-picked from commit 347bb4448c2155eb2310923ccaa4be5677649003)

The scale_delta function for shift / multiply with 31-bit
precision moves to a common header so it can be used by both
kernel and kvm module.

[142/143] KVM: x86: Fix a possible backwards warp of kvmclock

[Greg KH]

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

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

From: Zachary Amsden <zamsden@redhat.com>

(backported from commit 1d5f066e0b63271b67eac6d3752f8aa96adcbddb)


Kernel time, which advances in discrete steps may progress much slower
than TSC.  As a result, when kvmclock is adjusted to a new base, the
apparent time to the guest, which runs at a much higher, nsec scaled
rate based on the current TSC, may have already been observed to have
a larger value (kernel_ns + scaled tsc) than the value to which we are
setting it (kernel_ns + 0).

We must instead compute the clock as potentially observed by the guest
for kernel_ns to make sure it does not go backwards.

[143/143] KVM: x86: Fix kvmclock bug

[Greg KH]

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

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

From: Zachary Amsden <zamsden@redhat.com>

(backported from commit 28e4639adf0c9f26f6bb56149b7ab547bf33bb95)

If preempted after kvmclock values are updated, but before hardware
virtualization is entered, the last tsc time as read by the guest is
never set.  It underflows the next time kvmclock is updated if there
has not yet been a successful entry / exit into hardware virt.

Fix this by simply setting last_tsc to the newly read tsc value so
that any computed nsec advance of kvmclock is nulled.
