ACPI / PM: Do not enable GPEs for system wakeup in advance
After commit 9630bdd9b15d2f489c646d8bc04b60e53eb5ec78
(ACPI: Use GPE reference counting to support shared GPEs) the wakeup
enable mask bits of GPEs are set as soon as the GPEs are enabled to
wake up the system. Unfortunately, this leads to a regression
reported by Michal Hocko, where a system is woken up from ACPI S5 by
a device that is not supposed to do that, because the wakeup enable
mask bit of this device's GPE is always set when
acpi_enter_sleep_state() calls acpi_hw_enable_all_wakeup_gpes(),
although it should only be set if the device is supposed to wake up
the system from the target state.
To work around this issue, rework the ACPI power management code so
that GPEs are not enabled to wake up the system upfront, but only
during a system state transition when the target state of the system
is known. [Of course, this means that the reference counting of
"wakeup" GPEs doesn't really make sense and it is sufficient to
set/unset the wakeup mask bits for them during system sleep
transitions. This will allow us to simplify the GPE handling code
quite a bit, but that change is too intrusive for 2.6.35.]

Subject: ACPI / ACPICA: Do not attempt to disable GPE when installing handler

ACPI / ACPICA: Do not attempt to disable GPE when installing handler
Commit 0f849d2cc6863c7874889ea60a871fb71399dd3f (ACPICA: Minimize
the differences between linux GPE code and ACPICA code base)
introduced a change attempting to disable a GPE before installing
a handler for it in acpi_install_gpe_handler() which was incorrect.
First, the GPE disabled by it is never enabled again (except during
resume) which leads to battery insert/remove events not being
reported on the Maxim Levitsky's machine. Second, the disabled
GPE is still reported as enabled by the sysfs interface that only
checks its enable register's enable_for_run mask.
Revert this change for now, because it causes more damage to happen
than the bug it was supposed to fix.

ACPI / ACPICA: Use helper function for computing GPE masks
In quite a few places ACPICA needs to compute a GPE enable mask with
only one bit, corresponding to a given GPE, set. Currently, that
computation is always open coded which leads to unnecessary code
duplication. Fix this by introducing a helper function for computing
one-bit GPE enable masks and using it where appropriate.

Subject: ACPI / ACPICA: Fix low-level GPE manipulation code
X-Git-Tag: v2.6.35-rc4~72^2~6^2~3
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=fd247447c1d94a79d5cfc647430784306b3a8323
ACPI / ACPICA: Fix low-level GPE manipulation code
ACPICA uses acpi_ev_enable_gpe() for enabling GPEs at the low level,
which is incorrect, because this function only enables the GPE if the
corresponding bit in its enable register's enable_for_run mask is set.
This causes acpi_set_gpe() to work incorrectly if used for enabling
GPEs that were not previously enabled with acpi_enable_gpe(). As a
result, among other things, wakeup-only GPEs are never enabled by
acpi_enable_wakeup_device(), so the devices that use them are unable
to wake up the system.
To fix this issue remove acpi_ev_enable_gpe() and its counterpart
acpi_ev_disable_gpe() and replace acpi_hw_low_disable_gpe() with
acpi_hw_low_set_gpe() that will be used instead to manipulate GPE
enable bits at the low level. Make the users of acpi_ev_enable_gpe()
and acpi_ev_disable_gpe() call acpi_hw_low_set_gpe() instead and
make sure that GPE enable masks are only updated by acpi_enable_gpe()
and acpi_disable_gpe() when GPE reference counters change from 0
to 1 and from 1 to 0, respectively.

Subject: ACPI / ACPICA: Avoid writing full enable masks to GPE registers
X-Git-Tag: v2.6.35-rc4~72^2~6^2~2
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=c9a8bbb7704cbf515c0fc68970abbe4e91d68521
ACPI / ACPICA: Avoid writing full enable masks to GPE registers
ACPICA uses acpi_hw_write_gpe_enable_reg() to re-enable a GPE after
an event signaled by it has been handled. However, this function
writes the entire GPE enable mask to the GPE's enable register which
may not be correct. Namely, if one of the other GPEs in the same
register was previously enabled by acpi_enable_gpe() and subsequently
disabled using acpi_set_gpe(), acpi_hw_write_gpe_enable_reg() will
re-enable it along with the target GPE.
To fix this issue rework acpi_hw_write_gpe_enable_reg() so that it
calls acpi_hw_low_set_gpe() with a special action value,
ACPI_GPE_COND_ENABLE, that will make it only enable the GPE if the
corresponding bit in its register's enable_for_run mask is set.

ACPI / ACPICA: Fix GPE initialization
While developing the GPE reference counting code we overlooked the
fact that acpi_ev_update_gpes() could have enabled GPEs before
acpi_ev_initialize_gpe_block() was called. As a result, some GPEs
are enabled twice during the initialization.
To fix this issue avoid calling acpi_enable_gpe() from
acpi_ev_initialize_gpe_block() for the GPEs that have nonzero
runtime reference counters.

ACPI / ACPICA: Fix sysfs GPE interface
The sysfs interface allowing user space to disable/enable GPEs
doesn't work correctly, because a GPE disabled this way will be
re-enabled shortly by acpi_ev_asynch_enable_gpe() if it was
previosuly enabled by acpi_enable_gpe() (in which case the
corresponding bit in its enable register's enable_for_run mask is
set).
To address this issue make the sysfs GPE interface use
acpi_enable_gpe() and acpi_disable_gpe() instead of acpi_set_gpe()
so that GPE reference counters are modified by it along with the
values of GPE enable registers.

+Supported hardware
+------------------
+
+- All Apple laptops and desktops from 2005 onwards, except:
+ - the unibody Macbook (2009)
+ - Mac Pro (all versions)
+- Apple TV (all revisions)
+
+The remote will only support the 6 buttons of the original remotes
+as sold by Apple. See the next section if you want to use other remotes
+or want to use lirc with the device instead of the kernel driver.
+
+Using lirc (native) instead of the kernel driver
+------------------------------------------------
+
+First, you will need to disable the kernel driver for the receiver.
+
+This can be achieved by passing quirks to the usbhid driver.
+The quirk line would be:
+usbhid.quirks=0x05ac:0x8242:0x40000010
+
+With 0x05ac being the vendor ID (Apple, you shouldn't need to change this)
+With 0x8242 being the product ID (check the output of lsusb for your hardware)
+And 0x10 being "HID_QUIRK_HIDDEV_FORCE" and 0x40000000 being "HID_QUIRK_NO_IGNORE"
+
+This should force the creation of a hiddev device for the receiver, and
+make it usable under lirc.

Subject: ahci,ata_generic: let ata_generic handle new MBP w/ MCP89
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=c6353b4520788e34098bbf61c73fb9618ca7fdd6
ahci,ata_generic: let ata_generic handle new MBP w/ MCP89
For yet unknown reason, MCP89 on MBP 7,1 doesn't work w/ ahci under
linux but the controller doesn't require explicit mode setting and
works fine with ata_generic. Make ahci ignore the controller on MBP
7,1 and let ata_generic take it for now.
Reported in bko#15923.
https://bugzilla.kernel.org/show_bug.cgi?id=15923
NVIDIA is investigating why ahci mode doesn't work.

ata_generic: implement ATA_GEN_* flags and force enable DMA on MBP 7,1
[[ cebbert@redhat.com : backport to 2.6.34 ]]
IDE mode of MCP89 on MBP 7,1 doesn't set DMA enable bits in the BMDMA
status register. Make the following changes to work around the problem.
* Instead of using hard coded 1 in id->driver_data as class code
match, use ATA_GEN_CLASS_MATCH and carry the matched id in
host->private_data.
* Instead of matching PCI_VENDOR_ID_CENATEK, use ATA_GEN_FORCE_DMA
flag in id instead.
* Add ATA_GEN_FORCE_DMA to the id entry of MBP 7,1.

Btrfs: prohibit a operation of changing acl's mask when noacl mount option used
when used Posix File System Test Suite(pjd-fstest) to test btrfs,
some cases about setfacl failed when noacl mount option used.
I simplified used commands in pjd-fstest, and the following steps
can reproduce it.
------------------------
# cd btrfs-part/
# mkdir aaa
# setfacl -m m::rw aaa <- successed, but not expected by pjd-fstest.
------------------------
I checked ext3, a warning message occured, like as:
setfacl: aaa/: Operation not supported
Certainly, it's expected by pjd-fstest.
So, i compared acl.c of btrfs and ext3. Based on that, a patch created.
Fortunately, it works.

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
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:

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.

Since commit 4bdadb9785696439c6e2b3efe34aa76df1149c83 ("drm/i915:
Selectively enable self-reclaim"), we've been passing GFP_MOVABLE to the
i915 page allocator where we weren't before due to some over-eager
removal of the page mapping gfp_flags games the code used to play.
This caused hibernate on Intel hardware to result in a lot of memory
corruptions on resume. See for example

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: ethtool: Fix potential kernel buffer overflow in ETHTOOL_GRXCLSRLALL
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Fdavem%2Fnet-2.6.git;a=commitdiff_plain;h=db048b69037e7fa6a7d9e95a1271a50dc08ae233
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.

Legacy hypervisors (RHEL 5.0 and RHEL 5.1) do not handle guest writes to
cr4 gracefully. If a guest attempts to write a bit of cr4 that is
unsupported, then the HV is so offended it crashes the domain. While
later guest kernels (such as RHEL6) don't assume the HV supports all
features, they do expect nicer responses. That assumption introduced
code that probes whether or not xsave is supported early in the boot. So
now when attempting to boot a RHEL6 guest on RHEL5.0 or RHEL5.1 an early
crash will occur.
This patch is quite obviously an undesirable hack. The real fix for this
problem should be in the HV, and is, in later HVs. However, to support
running on old HVs, RHEL6 can take this small change. No impact will
occur for running on any RHEL HV (not even RHEL 5.5 supports xsave).
There is only potential for guest performance loss on upstream Xen.

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.

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.

Subject: [PATCH] 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.

From: Wey-Yi Guy <wey-yi.w.guy@intel.com>
Date: Fri, 5 Mar 2010 14:22:46 -0800
Subject: [PATCH] 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.

Subject: [PATCH 2/4 2.6.34.y] iwlwifi: manage QoS by mac stack
Date: Fri, 11 Jun 2010 17:05:12 +0200
commit e61146e36b40fd9d346118c40285913236c329f3 upstream.
We activate/deactivate QoS and setup default queue parameters in iwlwifi
driver. Mac stack do the same, so we do not need repeat that work here.
Stack also will tell when disable QoS, this will fix driver when working
with older APs, that do not have QoS implemented.
Patch make "force = true" in iwl_active_qos() assuming we always want
to do with QoS what mac stack wish.
Patch also remove unused qos_cap bits, do not initialize qos_active = 0,
as we have it initialized to zero by kzalloc.

It just hit me.
It's the offset calculation in reloc_location() which overflows:
return (void *)elf->hdr + sechdrs[section].sh_offset +
(r->r_offset - sechdrs[section].sh_addr);
E.g. for the first rodata r entry:
r->r_offset < sechdrs[section].sh_addr
and the expression in the parenthesis produces 0xFFFFFFE0 or something
equally wise.

KVM: MMU: fix conflict access permissions in direct sp
In no-direct mapping, we mark sp is 'direct' when we mapping the
guest's larger page, but its access is encoded form upper page-struct
entire not include the last mapping, it will cause access conflict.
For example, have this mapping:
[W]
/ PDE1 -> |---|
P[W] | | LPA
\ PDE2 -> |---|
[R]
P have two children, PDE1 and PDE2, both PDE1 and PDE2 mapping the
same lage page(LPA). The P's access is WR, PDE1's access is WR,
PDE2's access is RO(just consider read-write permissions here)
When guest access PDE1, we will create a direct sp for LPA, the sp's
access is from P, is W, then we will mark the ptes is W in this sp.
Then, guest access PDE2, we will find LPA's shadow page, is the same as
PDE's, and mark the ptes is RO.
So, if guest access PDE1, the incorrect #PF is occured.
Fixed by encode the last mapping access into direct shadow page

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.

commit 7d0d20a25c6f477fb198b85510c78156d7d7c5af
Author: Matthew Garrett <mjg@redhat.com>
Date: Tue Jun 9 20:11:47 2009 +0100
usb: Allow drivers to enable USB autosuspend on a per-device basis
USB autosuspend is currently only enabled by default for hubs. On other
hardware the decision is made by userspace. This is unnecessary in cases
where we know that the hardware supports autosuspend, so this patch adds
a function to allow drivers to enable it at probe time.

Subject: [PATCH] [intel_iommu] Default to igfx_off
From: drago01 <drago01@gmail.com>
To: fedora-kernel-list <fedora-kernel-list@redhat.com>
This option seems to causes way to many issues, it is
being investigated by Intel's chipset team for months now and
we still don't have any outcome.
The results so far are "black screen when starting X",
"system hangs when using GL", "system does not resume".
The patch adds an intel_iommu=igfx_on option, which makes it opt in,
rather than opt out.
