2013-07-19bridge: do not call setup_timer() multiple timesEric Dumazet
commit 9f00b2e7cf24 ("bridge: only expire the mdb entry when query is received") added a nasty bug as an active timer can be reinitialized. setup_timer() must be done once, no matter how many time mod_timer() is called. br_multicast_new_group() is the right place to do this.

2013-07-20livelock avoidance in sget()Al Viro
Eric Sandeen has found a nasty livelock in sget() - take a mount(2) about to fail. The superblock is on ->fs_supers, ->s_umount is held exclusive, ->s_active is 1. Along comes two more processes, trying to mount the same thing; sget() in each is picking that superblock, bumping ->s_count and trying to grab ->s_umount. ->s_active is 3 now. Original mount(2) finally gets to deactivate_locked_super() on failure; ->s_active is 2, superblock is still ->fs_supers because shutdown will *not* happen until ->s_active hits 0. ->s_umount is dropped and now we have two processes chasing each other: s_active = 2, A acquired ->s_umount, B blocked A sees that the damn thing is stillborn, does deactivate_locked_super() s_active = 1, A drops ->s_umount, B gets it A restarts the search and finds the same superblock. And bumps it ->s_active. s_active = 2, B holds ->s_umount, A blocked on trying to get it ... and we are in the earlier situation with A and B switched places. The root cause, of course, is that ->s_active should not grow until we'd got MS_BORN. Then failing ->mount() will have deactivate_locked_super() shut the damn thing down. Fortunately, it's easy to do - the key point is that grab_super() is called only for superblocks currently on ->fs_supers, so it can bump ->s_count and grab ->s_umount first, then check MS_BORN and bump ->s_active; we must never increment ->s_count for superblocks past ->kill_sb(), but grab_super() is never called for those. The bug is pretty old; we would've caught it by now, if not for accidental exclusion between sget() for block filesystems; the things like cgroup or e.g. mtd-based filesystems don't have anything of that sort, so they get bitten. The right way to deal with that is obviously to fix sget()... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2013-07-19vxlan: fix igmp racesstephen hemminger
There are two race conditions in existing code for doing IGMP management in workqueue in vxlan. First, the vxlan_group_used function checks the list of vxlan's without any protection, and it is possible for open followed by close to occur before the igmp work queue runs. To solve these move the check into vxlan_open/stop so it is protected by RTNL. And split into two work structures so that there is no racy reference to underlying device state.

2013-07-19Btrfs: fix wrong write offset when replacing a deviceStefan Behrens
Miao Xie reported the following issue: The filesystem was corrupted after we did a device replace. Steps to reproduce: # mkfs.btrfs -f -m single -d raid10 <device0>..<device3> # mount <device0> <mnt> # btrfs replace start -rfB 1 <device4> <mnt> # umount <mnt> # btrfsck <device4> The reason for the issue is that we changed the write offset by mistake, introduced by commit 625f1c8dc. We read the data from the source device at first, and then write the data into the corresponding place of the new device. In order to implement the "-r" option, the source location is remapped using btrfs_map_block(). The read takes place on the mapped location, and the write needs to take place on the unmapped location. Currently the write is using the mapped location, and this commit changes it back by undoing the change to the write address that the aforementioned commit added by mistake.

Specifics: - Two cpufreq commits from the 3.10 cycle introduced regressions. The first of them was buggy (it did way much more than it needed to do) and the second one attempted to fix an issue introduced by the first one. Fixes from Srivatsa S Bhat revert both. - If autosleep triggers during system shutdown and the shutdown callbacks of some device drivers have been called already, it may crash the system. Fix from Liu Shuo prevents that from happening by making try_to_suspend() check system_state. - The ACPI memory hotplug driver doesn't clear its driver_data on errors which may cause a NULL poiter dereference to happen later. Fix from Toshi Kani. - The ACPI namespace scanning code should not try to attach scan handlers to device objects that have them already, which may confuse things quite a bit, and it should rescan the whole namespace branch starting at the given node after receiving a bus check notify event even if the device at that particular node has been discovered already. Fixes from Rafael J Wysocki. - New ACPI video blacklist entry for a system whose initial backlight setting from the BIOS doesn't make sense. From Lan Tianyu. - Garbage string output avoindance for ACPI PNP from Liu Shuo. - Two Kconfig fixes for issues introduced recently in the s3c24xx cpufreq driver (when moving the driver to drivers/cpufreq) from Paul Bolle. - Trivial comment fix in pm_wakeup.h from Chanwoo Choi" * tag 'pm+acpi-3.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / video: ignore BIOS initial backlight value for Fujitsu E753 PNP / ACPI: avoid garbage in resource name cpufreq: Revert commit 2f7021a8 to fix CPU hotplug regression cpufreq: s3c24xx: fix "depends on ARM_S3C24XX" in Kconfig cpufreq: s3c24xx: rename CONFIG_CPU_FREQ_S3C24XX_DEBUGFS PM / Sleep: Fix comment typo in pm_wakeup.h PM / Sleep: avoid 'autosleep' in shutdown progress cpufreq: Revert commit a66b2e to fix suspend/resume regression ACPI / memhotplug: Fix a stale pointer in error path ACPI / scan: Always call acpi_bus_scan() for bus check notifications ACPI / scan: Do not try to attach scan handlers to devices having them

2013-07-19arm64: use common reboot infrastructureMarc Zyngier
Commit 7b6d864b48d9 (reboot: arm: change reboot_mode to use enum reboot_mode) changed the way reboot is handled on arm, which has a direct impact on arm64 as we share the reset driver on the VE platform. The obvious fix is to move arm64 to use the same infrastructure.

2013-07-19arm64: mm: don't treat user cache maintenance faults as writesWill Deacon
On arm64, cache maintenance faults appear as data aborts with the CM bit set in the ESR. The WnR bit, usually used to distinguish between faulting loads and stores, always reads as 1 and (slightly confusingly) the instructions are treated as reads by the architecture. This patch fixes our fault handling code to treat cache maintenance faults in the same way as loads.

2013-07-19arm64: add '#ifdef CONFIG_COMPAT' for aarch32_break_handler()Chen Gang
If 'COMPAT' not defined, aarch32_break_handler() cannot pass compiling, and it can work independent with 'COMPAT', so remove dummy definition.
