2013-05-09batman-adv: check proto length before accessing proto string bufferMarek Lindner
batadv_param_set_ra() strips the trailing '\n' from the supplied string buffer without checking the length of the buffer first.

2013-05-09KVM: emulator: emulate SALCPaolo Bonzini
This is an almost-undocumented instruction available in 32-bit mode. I say "almost" undocumented because AMD documents it in their opcode maps just to say that it is unavailable in 64-bit mode (sections "A.2.1 One-Byte Opcodes" and "B.3 Invalid and Reassigned Instructions in 64-Bit Mode"). It is roughly equivalent to "sbb %al, %al" except it does not set the flags. Use fastop to emulate it, but do not use the opcode directly because it would fail if the host is 64-bit!

2013-05-09x86/microcode: Add local mutex to fix physical CPU hot-add deadlockKonrad Rzeszutek Wilk
This can easily be triggered if a new CPU is added (via ACPI hotplug mechanism) and from user-space you do: echo 1 > /sys/devices/system/cpu/cpu3/online (or wait for UDEV to do it) on a newly appeared physical CPU. The deadlock is that the "store_online" in drivers/base/cpu.c takes the cpu_hotplug_driver_lock() lock, then calls "cpu_up". "cpu_up" eventually ends up calling "save_mc_for_early" which also takes the cpu_hotplug_driver_lock() lock. And here is that lockdep thinks of it: smpboot: Stack at about ffff880075c39f44 smpboot: CPU3: has booted. microcode: CPU3 sig=0x206a7, pf=0x2, revision=0x25 ============================================= [ INFO: possible recursive locking detected ] 3.9.0upstream-10129-g167af0e #1 Not tainted --------------------------------------------- sh/2487 is trying to acquire lock: (x86_cpu_hotplug_driver_mutex){+.+.+.}, at: [<ffffffff81075512>] cpu_hotplug_driver_lock+0x12/0x20 but task is already holding lock: (x86_cpu_hotplug_driver_mutex){+.+.+.}, at: [<ffffffff81075512>] cpu_hotplug_driver_lock+0x12/0x20 other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(x86_cpu_hotplug_driver_mutex); lock(x86_cpu_hotplug_driver_mutex); *** DEADLOCK *** May be due to missing lock nesting notation 6 locks held by sh/2487: #0: (sb_writers#5){.+.+.+}, at: [<ffffffff811ca48d>] vfs_write+0x17d/0x190 #1: (&buffer->mutex){+.+.+.}, at: [<ffffffff812464ef>] sysfs_write_file+0x3f/0x160 #2: (s_active#20){.+.+.+}, at: [<ffffffff81246578>] sysfs_write_file+0xc8/0x160 #3: (x86_cpu_hotplug_driver_mutex){+.+.+.}, at: [<ffffffff81075512>] cpu_hotplug_driver_lock+0x12/0x20 #4: (cpu_add_remove_lock){+.+.+.}, at: [<ffffffff810961c2>] cpu_maps_update_begin+0x12/0x20 #5: (cpu_hotplug.lock){+.+.+.}, at: [<ffffffff810962a7>] cpu_hotplug_begin+0x27/0x60 Suggested-and-Acked-by: Borislav Petkov <bp@alien8.de> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Cc: fenghua.yu@intel.com Cc: xen-devel@lists.xensource.com Cc: stable@vger.kernel.org # for v3.9 Link: http://lkml.kernel.org/r/1368029583-23337-1-git-send-email-konrad.wilk@oracle.com Signed-off-by: Ingo Molnar <mingo@kernel.org>

2013-05-09watchdog: Fix race condition in registration codeGuenter Roeck
A race condition exists when registering the first watchdog device. Sequence of events: - watchdog_register_device calls watchdog_dev_register - watchdog_dev_register creates the watchdog misc device by calling misc_register. At that time, the matching character device (/dev/watchdog0) does not yet exist, and old_wdd is not set either. - Userspace gets an event and opens /dev/watchdog - watchdog_open is called and sets wdd = old_wdd, which is still NULL, and tries to dereference it. This causes the kernel to panic. Seen with systemd trying to open /dev/watchdog immediately after it was created.

2013-05-08rbd: only set up watch for mapped imagesAlex Elder
Any changes to parent images are immaterial to any mapped clone. So there is no need to have a watch event registered on header objects except for the header object of an image that is mapped. In fact, a watch request is a write operation, and we may only have read access to a parent image. We can't set up the watch request until we know the name of the header object though. So pass a flag to rbd_dev_image_probe() to indicate whether this probe is for a mapping or for a parent image. Change the second parameter to rbd_dev_header_watch_sync() be Boolean while we're at it.

2013-05-08rbd: set mapping read-only flag in rbd_add()Alex Elder
The rbd_dev->mapping field for a parent image is not meaningful. Since rbd_image_probe() is used both for images being mapped and their parents, it doesn't make sense to set that flag in that function. So move the setting of the mapping.read_only flag out of rbd_dev_image_probe() and into rbd_add() instead.

2013-05-08rbd: support reading parent page dataAlex Elder
Currently, rbd_img_parent_read() assumes the incoming object request contains bio data. But if a layered image is part of a multi-layer stack of images it will result in read requests of page data to parent images. Fortunately, it's not hard to add support for page data.

2013-05-08rbd: fix an incorrect assertion conditionAlex Elder
In rbd_img_obj_parent_read_full_callback() there is an assertion intended to verify the size of the image request for a full parent read was the size of the original request's target object. But assertion was looking at the parent image order rather than the original one, and these values can differ. Fix that.

2013-05-08ARM: dts: Configure and fix the McSPI pins for 4430sdpTony Lindgren
The bootloader configures the pins, but has pull bits set without pull enable bits. While this is harmless, and won't do anything, it seems to cause confusion at least for me every time looking at the pin configuration. Fix it for DT based boot. Signed-off-by: Tony Lindgren <tony@atomide.com>
