2011-04-26xfrm: Fix replay window size calculation on initializationSteffen Klassert
On replay initialization, we compute the size of the replay buffer to see if the replay window fits into the buffer. This computation lacks a mutliplication by 8 because we need the size in bit, not in byte. So we might return an error even though the replay window would fit into the buffer.

2011-04-26perf events, x86: Work around the Nehalem AAJ80 erratumIngo Molnar
On Nehalem CPUs the retired branch-misses event can be completely bogus, when there are no branch-misses occuring. When there are a lot of branch misses then the count is pretty accurate. Still, this leaves us with an event that over-counts a lot. Detect this erratum and work it around by using BR_MISP_EXEC.ANY events. These will also count speculated branches but still it's a lot more precise in practice than the architectural event.

2011-04-26OMAP3+: voltage: remove initial voltageNishanth Menon
Blindly setting 1.2V in the initial structure may not even match the default voltages stored in the voltage table which are supported for the domain. For example, OMAP3430 core domain does not use 1.2V and ends up generating a warning on the first transition. Further, since omap2_set_init_voltage is called as part of the pm framework's initialization sequence to configure the voltage required for the current OPP, the call does(and has to) setup the system voltage(curr_volt as a result) using the right mechanisms appropriate for the system at that point of time. This also overrides initialization we are currently doing in voltage.c making it redundant. So, remove the wrong and redundant initialization.

2011-04-26ACPI / PM: Avoid infinite recurrence while registering power resourcesRafael J. Wysocki
There is at least one BIOS with a DSDT containing a power resource object with a _PR0 entry pointing back to that power resource. In consequence, while registering that power resource acpi_bus_get_power_flags() sees that it depends on itself and tries to register it again, which leads to an infinitely deep recurrence. This problem was introduced by commit bf325f9538d8c89312be305b9779e (ACPI / PM: Register power resource devices as soon as they are needed). To fix this problem use the observation that power resources cannot be power manageable and prevent acpi_bus_get_power_flags() from being called for power resource objects.

2011-04-26PM / Wakeup: Fix initialization of wakeup-related device sysfs filesRafael J. Wysocki
It turns out that some PCI devices are only found to be wakeup-capable during registration, in which case, when device_set_wakeup_capable() is called, device_is_registered() already returns 'true' for the given device, but dpm_sysfs_add() hasn't been called for it yet. This leads to situations in which the device's power.can_wakeup flag is not set as requested because of failing wakeup_sysfs_add() and its wakeup-related sysfs files are not created, although they should be present. This is a post-2.6.38 regression introduced by commit cb8f51bdadb7969139c2e39c2defd4cde98c1 (PM: Do not create wakeup sysfs files for devices that cannot wake up). To work around this problem initialize the device's power.entry field to an empty list head and make device_set_wakeup_capable() check if it is still empty before attempting to add the devices wakeup-related sysfs files with wakeup_sysfs_add(). Namely, if power.entry is still empty at this point, device_pm_add() hasn't been called yet for the device and its wakeup-related files will be created later, so device_set_wakeup_capable() doesn't have to create them.

2011-04-25SELINUX: Make selinux cache VFS RCU walks safeEric Paris
Now that the security modules can decide whether they support the dcache RCU walk or not it's possible to make selinux a bit more RCU friendly. The SELinux AVC and security server access decision code is RCU safe. A specific piece of the LSM audit code may not be RCU safe. This patch makes the VFS RCU walk retry if it would hit the non RCU safe chunk of code. It will normally just work under RCU. This is done simply by passing the VFS RCU state as a flag down into the avc_audit() code and returning ECHILD there if it would have an issue.

After 57db4e8d73ef2b5e94a3f412108dff2576670a8a changed eCryptfs to write-back caching, eCryptfs page writeback updates the lower inode times due to the use of vfs_write() on the lower file. To preserve inode metadata changes, such as 'cp -p' does with utimensat(), we need to flush all dirty pages early in ecryptfs_setattr() so that the user-updated lower inode metadata isn't clobbered later in writeback. https://bugzilla.kernel.org/show_bug.cgi?id=33372 Reported-by: Rocko <rockorequin@hotmail.com> Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
2011-04-25eCryptfs: Handle failed metadata read in lookupTyler Hicks
When failing to read the lower file's crypto metadata during a lookup, eCryptfs must continue on without throwing an error. For example, there may be a plaintext file in the lower mount point that the user wants to delete through the eCryptfs mount. If an error is encountered while reading the metadata in lookup(), the eCryptfs inode's size could be incorrect. We must be sure to reread the plaintext inode size from the metadata when performing an open() or setattr(). The metadata is already being read in those paths, so this adds minimal performance overhead. This patch introduces a flag which will track whether or not the plaintext inode size has been read so that an incorrect i_size can be fixed in the open() or setattr() paths. https://bugs.launchpad.net/bugs/509180 Cc: <stable@kernel.org> Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com>
