Input: add appleir USB driver
This driver was originally written by James McKenzie, updated by
Greg Kroah-Hartman, further updated by myself, with suspend support
added.
More recent versions of the IR receiver are also supported through
a patch by Alex Karpenko.
Tested on a MacbookAir1,1

commit 6ffcbf68913840e9e882db14441576ffee6eba0c

Add HID_QUIRK_HIDDEV_FORCE and HID_QUIRK_NO_IGNORE
Add two quirks to make it possible for usbhid module options to
override whether a device is ignored (HID_QUIRK_NO_IGNORE) and
whether to connect a hiddev device (HID_QUIRK_HIDDEV_FORCE).
Passing HID_QUIRK_NO_IGNORE for your device means that it will
not be ignored by the HID layer, even if present in a blacklist.
HID_QUIRK_HIDDEV_FORCE will force the creation of a hiddev for that
device, making it accessible from user-space.
Tested with an Apple IR Receiver, switching it from using appleir
to using lirc's macmini driver.

Subject: ALSA: usbmixer - add possibility to remap dB values
USB devices tends to represent dB ranges in different way than ALSA expects.
Add possibility to override these values and add guessed values for
SoundBlaster MP3+.
Also rename 'Capture Input Source' control to 'Capture Source' for
SoundBlaster MP3+ and Extigy.

CIFS: Fix DNS resolver build
In file included from fs/cifs/dns_resolve.c:29:
fs/cifs/dns_resolve.h:27: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'cifs_init_dns_resolver'
Just remove the __init and __exit attributes from the init and exit
functions. __exit was removed upstream in 51c20fcced5badee0e2021c6c89f44aa3cbd72aa
anyway, and there's no point trying to save every byte by fixing
this properly.

Subject: CIFS: Fix a malicious redirect problem in the DNS lookup code
X-Git-Tag: v2.6.35-rc6~6
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=4c0c03ca54f72fdd5912516ad0a23ec5cf01bda7
CIFS: Fix a malicious redirect problem in the DNS lookup code
[ trivial backport to 2.6.3[23] : cebbert@redhat.com ]
Fix the security problem in the CIFS filesystem DNS lookup code in which a
malicious redirect could be installed by a random user by simply adding a
result record into one of their keyrings with add_key() and then invoking a
CIFS CFS lookup [CVE-2010-2524].
This is done by creating an internal keyring specifically for the caching of
DNS lookups. To enforce the use of this keyring, the module init routine
creates a set of override credentials with the keyring installed as the thread
keyring and instructs request_key() to only install lookup result keys in that
keyring.
The override is then applied around the call to request_key().
This has some additional benefits when a kernel service uses this module to
request a key:
(1) The result keys are owned by root, not the user that caused the lookup.
(2) The result keys don't pop up in the user's keyrings.
(3) The result keys don't come out of the quota of the user that caused the
lookup.
The keyring can be viewed as root by doing cat /proc/keys:
2a0ca6c3 I----- 1 perm 1f030000 0 0 keyring .dns_resolver: 1/4
It can then be listed with 'keyctl list' by root.
# keyctl list 0x2a0ca6c3
1 key in keyring:
726766307: --alswrv 0 0 dns_resolver: foo.bar.com

Subject: CRED: Fix get_task_cred() and task_state() to not resurrect dead credentials
X-Git-Tag: v2.6.35~11
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=de09a9771a5346029f4d11e4ac886be7f9b
CRED: Fix get_task_cred() and task_state() to not resurrect dead credentials
It's possible for get_task_cred() as it currently stands to 'corrupt' a set of
credentials by incrementing their usage count after their replacement by the
task being accessed.
What happens is that get_task_cred() can race with commit_creds():
TASK_1 TASK_2 RCU_CLEANER
-->get_task_cred(TASK_2)
rcu_read_lock()
__cred = __task_cred(TASK_2)
-->commit_creds()
old_cred = TASK_2->real_cred
TASK_2->real_cred = ...
put_cred(old_cred)
call_rcu(old_cred)
[__cred->usage == 0]
get_cred(__cred)
[__cred->usage == 1]
rcu_read_unlock()
-->put_cred_rcu()
[__cred->usage == 1]
panic()
However, since a tasks credentials are generally not changed very often, we can
reasonably make use of a loop involving reading the creds pointer and using
atomic_inc_not_zero() to attempt to increment it if it hasn't already hit zero.
If successful, we can safely return the credentials in the knowledge that, even
if the task we're accessing has released them, they haven't gone to the RCU
cleanup code.
We then change task_state() in procfs to use get_task_cred() rather than
calling get_cred() on the result of __task_cred(), as that suffers from the
same problem.
Without this change, a BUG_ON in __put_cred() or in put_cred_rcu() can be
tripped when it is noticed that the usage count is not zero as it ought to be,
for example:

Subject: direct-io: move aio_complete into ->end_io
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=40e2e97316af6e62affab7a392e792494b8d9dde
direct-io: move aio_complete into ->end_io
Filesystems with unwritten extent support must not complete an AIO request
until the transaction to convert the extent has been commited. That means
the aio_complete calls needs to be moved into the ->end_io callback so
that the filesystem can control when to call it exactly.
This makes a bit of a mess out of dio_complete and the ->end_io callback
prototype even more complicated.

Subject: drm/i915: add 'reclaimable' to i915 self-reclaimable page allocations
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=cd9f040df6ce46573760a507cb88192d05d27d86
drm/i915: add 'reclaimable' to i915 self-reclaimable page allocations
The hibernate issues that got fixed in commit 985b823b9192 ("drm/i915:
fix hibernation since i915 self-reclaim fixes") turn out to have been
incomplete. Vefa Bicakci tested lots of hibernate cycles, and without
the __GFP_RECLAIMABLE flag the system eventually fails to resume.
With the flag added, Vefa can apparently hibernate forever (or until he
gets bored running his automated scripts, whichever comes first).
The reclaimable flag was there originally, and was one of the flags that
were dropped (unintentionally) by commit 4bdadb978569 ("drm/i915:
Selectively enable self-reclaim") that introduced all these problems,
but I didn't want to just blindly add back all the flags in commit
985b823b9192, and it looked like __GFP_RECLAIM wasn't necessary. It
clearly was.
I still suspect that there is some subtle reason we're missing that
causes the problems, but __GFP_RECLAIMABLE is certainly not wrong to use
in this context, and is what the code historically used. And we have no
idea what the causes the corruption without it.

From: Jesse Barnes <jbarnes@virtuousgeek.org>
commit 1918ad77f7f908ed67cf37c505c6ad4ac52f1ecf upstream.
My PIPE_CONTROL fix (just sent via Eric's tree) was buggy; I was
testing a whole set of patches together and missed a conversion to the
new HAS_PIPE_CONTROL macro, which will cause breakage on non-Ironlake
965 class chips. Fortunately, the fix is trivial and has been tested.
Be sure to use the HAS_PIPE_CONTROL macro in i915_get_gem_seqno, or
we'll end up reading the wrong graphics memory, likely causing hangs,
crashes, or worse.

drm/i915: Make G4X-style PLL search more permissive
Fixes an Ironlake laptop with a 68.940MHz 1280x800 panel and 120MHz SSC
reference clock.
More generally, the 0.488% tolerance used before is just too tight to
reliably find a PLL setting. I extracted the search algorithm and
modified it to find the dot clocks with maximum error over the valid
range for the given output type:
http://people.freedesktop.org/~ajax/intel_g4x_find_best_pll.c
This gave:
Worst dotclock for Ironlake DAC refclk is 350000kHz (error 0.00571)
Worst dotclock for Ironlake SL-LVDS refclk is 102321kHz (error 0.00524)
Worst dotclock for Ironlake DL-LVDS refclk is 219642kHz (error 0.00488)
Worst dotclock for Ironlake SL-LVDS SSC refclk is 84374kHz (error 0.00529)
Worst dotclock for Ironlake DL-LVDS SSC refclk is 183035kHz (error 0.00488)
Worst dotclock for G4X SDVO refclk is 50000kHz (error 0.17332)
Worst dotclock for G4X HDMI refclk is 334400kHz (error 0.00478)
Worst dotclock for G4X SL-LVDS refclk is 95571kHz (error 0.00449)
Worst dotclock for G4X DL-LVDS refclk is 224000kHz (error 0.00510)
The SDVO number looks a bit suspicious, which I haven't tracked down
yet. But it's clear that the old threshold is too tight.

Subject: drm/i915: use PIPE_CONTROL instruction on Ironlake and Sandy Bridge
From: Jesse Barnes <jbarnes@virtuousgeek.org>
commit e552eb7038a36d9b18860f525aa02875e313fe16 upstream.
Since 965, the hardware has supported the PIPE_CONTROL command, which
provides fine grained GPU cache flushing control. On recent chipsets,
this instruction is required for reliable interrupt and sequence number
reporting in the driver.
So add support for this instruction, including workarounds, on Ironlake
and Sandy Bridge hardware.

Subject: [PATCH] drm/i915: Be extra careful about A/D matching for multifunction SDVO
If we're both RGB and TMDS capable, we'll have set up one connector for
each. When determining connectivity, require analog/digital state in
the EDID block to match analog/digital support in the connector.
Otherwise, both DVI and VGA will appear to be connected.

From ef59fcdd9d7fe818d36a0072c80770c0d1a3cc9c Mon Sep 17 00:00:00 2001

Subject: [PATCH] drm/i915: Fix DDC bus selection for multifunction SDVO
Multifunction SDVO cards stopped working after 14571b4, and would report
something that looked remarkably like an ADD2 SPD ROM instead of EDID.
This appears to be because DDC bus selection was utterly horked by that
commit; controlled_output was no longer always a single bit, so
intel_sdvo_select_ddc_bus would pick bus 0, which is (unsurprisingly)
the SPD ROM bus, not a DDC bus.
So, instead of that, let's just use the DDC bus the child device table
tells us to use. I'm guessing at the bitmask and shifting from VBIOS
dumps, but it can't possibly be worse.
cf. https://bugzilla.redhat.com/584229

Subject: [PATCH] drm/nouveau: disable acceleration on NVA3/NVA5/NVA8 by default
There's an GPU lockup problem for which the cause is currently unknown
on these chipsets.
Until it's resolved, it's better to leave the user with a working system
without acceleration than to have random lockups.
With this patch, acceleration will be off by default if a known problem
chipset is detected, but can be re-enabled with nouveau.noaccel=0 on
the kernel commandline.

rhbz#602663
When VRAM is running out it's possible that the client's push buffers get
evicted to main memory. When they're validated back in, the GPU may
be used for the copy back to VRAM, but the existing synchronisation code
only deals with inter-channel sync, not sync between PFIFO and PGRAPH on
the same channel. This leads to PFIFO fetching from command buffers that
haven't quite been copied by PGRAPH yet.
This patch marks push buffers as so, and forces any GPU-assisted buffer
moves to be done on a different channel, which triggers the correct
synchronisation to happen before we submit them.
After discussion with another nouveau developer, it was agreed that while
this patch is fine in itself, that we'd prefer to work out a nicer, but
likely much more invasive, fix upstream.

ethtool: Fix potential kernel buffer overflow in ETHTOOL_GRXCLSRLALL
On a 32-bit machine, info.rule_cnt >= 0x40000000 leads to integer
overflow and the buffer may be smaller than needed. Since
ETHTOOL_GRXCLSRLALL is unprivileged, this can presumably be used for at
least denial of service.

Subject: ext4: move aio completion after unwritten extent conversion

ext4: move aio completion after unwritten extent conversion
This patch is to be applied upon Christoph's "direct-io: move aio_complete
into ->end_io" patch. It adds iocb and result fields to struct ext4_io_end_t,
so that we can call aio_complete from ext4_end_io_nolock() after the extent
conversion has finished.
I have verified with Christoph's aio-dio test that used to fail after a few
runs on an original kernel but now succeeds on the patched kernel.
See http://thread.gmane.org/gmane.comp.file-systems.ext4/19659 for details.

hid/hid-sony: fix sony_set_operational_bt
Don't send the report type as part of the data, this prevents the
controller from going into the operational state at all.
This is completely equivalent to what the code originally meant to accomplish:
as per in net/bluetooth/hidp/core.c::hidp_output_raw_report(), by using
HID_FEATURE_REPORT here, what will be actually sent is
(HIDP_TRANS_SET_REPORT | HIDP_DATA_RTYPE_FEATURE) which is exactly 0x53.

HID: make Wacom modesetting failures non-fatal
With Wacom tablet mode-setting moved from userspace into kernel,
we don't have to consider failures of device queries through the
_raw callback as hard failure, as the driver can safely continue
anyway.
This is consistent with the current USB driver in wacom_sys.c

Author: Jiri Kosina <jkosina@suse.cz>

HID: make raw reports possible for both feature and output reports
In commit 2da31939a42 ("Bluetooth: Implement raw output support for HIDP
layer"), support for Bluetooth hid_output_raw_report was added, but it
pushes the data to the intr socket instead of the ctrl one. This has been
fixed by 6bf8268f9a91f1 ("Bluetooth: Use the control channel for raw HID reports")
Still, it is necessary to distinguish whether the report in question should be
either FEATURE or OUTPUT. For this, we have to extend the generic HID API,
so that hid_output_raw_report() callback provides means to specify this
value so that it can be passed down to lower level hardware drivers (currently
Bluetooth and USB).
Based on original patch by Bastien Nocera <hadess@hadess.net>

From dec23057518b7035117a1a732aa48be6d34f1be8 Mon Sep 17 00:00:00 2001
From: Andrew Lutomirski <luto@mit.edu>
Date: Sat, 12 Jun 2010 09:21:18 +0000
Subject: i915: Fix CRT hotplug regression in 2.6.35-rc1
Commit 7a772c492fcfffae812ffca78a628e76fa57fe58 has two bugs which
made the hotplug problems on my laptop worse instead of better.
First, it did not, in fact, disable the CRT plug interrupt -- it
disabled all the other hotplug interrupts. It seems rather doubtful
that that bit of the patch fixed anything, so let's just remove it.
(If you want to add it back, you probably meant ~CRT_HOTPLUG_INT_EN.)
Second, on at least my GM45, setting CRT_HOTPLUG_ACTIVATION_PERIOD_64
and CRT_HOTPLUG_VOLTAGE_COMPARE_50 (when they were previously unset)
causes a hotplug interrupt about three seconds later. The old code
never restored PORT_HOTPLUG_EN so this could only happen once, but
they new code restores those registers. So just set those bits when
we set up the interrupt in the first place.

ibmvscsi uses dma_unmap_single() for buffers mapped via
dma_map_sg(). It works however it's the API violation. The DMA debug

Input: synaptics - relax capability ID checks on newer hardware
Older firmwares fixed the middle byte of the Synaptics capabilities
query to 0x47, but starting with firmware 7.5 the middle byte
represents submodel ID, sometimes also called "dash number".

Subject: [PATCH] iwlwifi: Recover TX flow failure
Monitors the tx statistics to detect the drop in throughput.
When the throughput drops, the ratio of the actual_ack_count and the
expected_ack_count also drops. At the same time, the aggregated
ba_timeout (the number of ba timeout retries) also rises. If the
actual_ack_count/expected_ack_count ratio is 0 and the number of ba
timeout retries rises to BA_TIMEOUT_MAX, no tx packets can be delivered.
Reloading the uCode and bring the system back to normal operational
state.

It is possible for internal scan to race against itself if the device is
not returning the scan results from first requests. What happens in this
case is the cleanup done during the abort of the first internal scan also
cleans up part of the new scan, causing it to access memory it shouldn't.
Here are details:
* First internal scan is triggered and scan command sent to device.
* After seven seconds there is no scan results so the watchdog timer
triggers a scan abort.
* The scan abort succeeds and a SCAN_COMPLETE_NOTIFICATION is received for
failed scan.
* During processing of SCAN_COMPLETE_NOTIFICATION we clear STATUS_SCANNING
and queue the "scan_completed" work.
** At this time, since the problem that caused the internal scan in first
place is still present, a new internal scan is triggered.
The behavior at this point is a bit different between 2.6.34 and 2.6.35
since 2.6.35 has a lot of this synchronized. The rest of the race
description will thus be generalized.
** As part of preparing for the scan "is_internal_short_scan" is set to
true.
* At this point the completion work for fist scan is run. As part of this
there is some locking missing around the "is_internal_short_scan"
variable and it is set to "false".
** Now the second scan runs and it considers itself a real (not internal0
scan and thus causes problems with wrong memory being accessed.
The fix is twofold.
* Since "is_internal_short_scan" should be protected by mutex, fix this in
scan completion work so that changes to it can be serialized.
* Do not queue a new internal scan if one is in progress.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=15824

commit 88be026490ed89c2ffead81a52531fbac5507e01
Author: Johannes Berg <johannes.berg@intel.com>

iwlwifi: fix scan races
When an internal scan is started, nothing protects the
is_internal_short_scan variable which can cause crashes,
cf. https://bugzilla.kernel.org/show_bug.cgi?id=15667.
Fix this by making the short scan request use the mutex
for locking, which requires making the request go to a
work struct so that it can sleep.

iwlwifi: Adjusting PLCP error threshold for 1000 NIC
While testing the station with the NIC 1000 family, it is found that
the plcp error can easily exceed 50 value in 100mSecs. This creates
unneccessary radio reset/tuning. This patch raises the PLCP error
threshold of the NIC 1000 from 50 to 200 error count.

iwlwifi: Logic to control how frequent radio should be reset if needed
Add additional logic for internal scan routine to control how
frequent this function should be performed.
The intent of this function is to reset/re-tune the radio and bring the
RF/PHY back to normal state, it does not make sense calling it too
frequent,
if reset the radio can not bring it back to normal state, it indicate
there are other reason to cause the radio not operate correctly.

iwlwifi: Recover TX flow failure
Monitors the tx statistics to detect the drop in throughput.
When the throughput drops, the ratio of the actual_ack_count and the
expected_ack_count also drops. At the same time, the aggregated
ba_timeout (the number of ba timeout retries) also rises. If the
actual_ack_count/expected_ack_count ratio is 0 and the number of ba
timeout retries rises to BA_TIMEOUT_MAX, no tx packets can be delivered.
Reloading the uCode and bring the system back to normal operational
state.

iwlwifi: Recover TX flow stall due to stuck queue
Monitors the internal TX queues periodically. When a queue is stuck
for some unknown conditions causing the throughput to drop and the
transfer is stop, the driver will force firmware reload and bring the
system back to normal operational state.
The iwlwifi devices behave differently in this regard so this feature is
made part of the ops infrastructure so we can have more control on how to
monitor and recover from tx queue stall case per device.

commit 3e4fb5faefb57824f2e42305b3d5907845af978c

iwlwifi: Tune radio to prevent unexpected behavior
We have seen the throughput dropped due to external noisy environment
and the radio is out of tune. There are lot of plcp errors indicating
this condition. Eventually the station can get de-authenticated by the
Access Point. By resetting and tuning the radio, the plcp errors are
reduced or eliminated and the throughput starts to rise.
To prevent unexpected behavior such as drop in throughput or deauthentication,
- The change provides the driver feature to monitor and tune the radio base on
the statistics notification from the uCode.
- It also allows the setting of the plcp error rate threshold via
the plcp_delta under debugfs interface.

Backport of the following upstream commit...
commit afbdd69af0e6a0c40676d4d4b94a0a4414708eaa
Author: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Date: Fri Jan 22 14:22:43 2010 -0800
iwlwifi: add function to reset/tune radio if needed
Adding "radio reset" function to help reset and stabilize the radio.
During normal operation, sometime for unknown reason, radio encounter
problem and can not recover by itself; the best way to
recover from it is to reset and re-tune the radio. Currently, there is
no RF reset command available, but since radio will get reset when
switching channel, use internal hw scan request to force radio
reset and get back to normal operation state.
The internal hw scan will only perform passive scan on the first
available channel (not the channel being used) in associated state. The
request should be ignored if already performing scan operation or STA is
not in associated state.
Also include an "internal_scan" debugfs file to help trigger the
internal scan from user mode.

Subject: [PATCH] iwlwifi: code cleanup for connectivity recovery
Backport of the following upstream commit...
Split the connectivity check and recovery routine into separated
functions based on the types
1. iwl_good_ack_health() - check for ack count
2. iwl_good_plcp_health() - check for plcp error
commit fa8f130c504223d25c116b3d23787f465dfb1317
Author: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Date: Fri Mar 5 14:22:46 2010 -0800
Based on the type of errors being detected, different recovery methods
will be used to bring the system back to normal operational state.
iwlwifi: code cleanup for connectivity recovery
Split the connectivity check and recovery routine into separated
functions based on the types
1. iwl_good_ack_health() - check for ack count
2. iwl_good_plcp_health() - check for plcp error
Based on the type of errors being detected, different recovery methods
will be used to bring the system back to normal operational state.
Because different NIC has different HW and uCode, the behavior is also
different; these functions thus now form part of the ops infrastructure,
so we can have more control on how to monitor and recover from error condition
case per device.

iwlwifi: multiple force reset mode
Provide the function to perform different type of uCode reset/reload operation.
When uCode detect error and can not fix itself, this iwl_force_reset()
function allow driver to perform the necessary reset/reload functions and help
to bring uCode back to normal operation state.
Currently only 2 type of force reset are available:
- reset radio
- reload firmware

iwlwifi: separated time check for different type of force reset
Use different timing duration check for different type of force reset,
force reset request can come from different source and based on
different reason; one type of reset request should not block other type of
reset request.
Adding structure to keep track of different force reset request.

commit 0c99c5288eb9b1bbc9684b0ec0fd7efc578749b3
Author: Zhang Rui <rui.zhang@intel.com>
Date: Thu Dec 17 16:02:08 2009 +0800
ACPI: Disable explicit power state retrieval on fans
If the ACPI power state can be got both directly and indirectly,
we prefer to get it indirectly.
https://bugzilla.redhat.com/show_bug.cgi?id=531916 describes a
system with a _PSC method for the fan that always returns "on".
There's no benefit in us always requesting the state of the fan
when performing transitions - we want to do everything we can
to ensure that the fan turns on when it should do, not risk
hardware damage by believing the hardware when it tells us the
fan is already on. Given that the Leading Other OS(tm) works fine
on this machine, it seems likely that it behaves in much this way.

commit 7ba0dea4158155a68b833982199691dbc2d4e6dc
Author: Matthew Garrett <mjg@redhat.com>
Date: Mon Apr 19 16:51:39 2010 -0400
acpi: Fall back to manually changing SCI_EN
The ACPI spec tells us that the ACPI SCI_EN bit is under hardware control
and shouldn't be touched by the OS. It seems that the Leading Other OS
ignores this and some machines expect this behaviour. We have a blacklist
for these, but given that we're able to detect the failure case and the
alternative to breaking the spec is letting the machine crash and burn,
let's try falling back when we know the alternative is a mostly-dead
machine.
