commit 7a401a97 upstream. bdi_prune_sb() in bdi_unregister() attempts to removes the bdi links from all super_blocks and then del_timer_sync() the writeback timer. However, this can race with __mark_inode_dirty(), leading to bdi_wakeup_thread_delayed() rearming the writeback timer on the bdi we're unregistering, after we've called del_timer_sync(). This can end up with the bdi being freed with an active timer inside it, as in the case of the following dump after the removal of an SD card. Fix this by redoing the del_timer_sync() in bdi_destory(). ------------[ cut here ]------------ WARNING: at /home/rabin/kernel/arm/lib/debugobjects.c:262 debug_print_object+0x9c/0xc8() ODEBUG: free active (active state 0) object type: timer_list hint: wakeup_timer_fn+0x0/0x180 Modules linked in: Backtrace: [<c00109dc>] (dump_backtrace+0x0/0x110) from [<c0236e4c>] (dump_stack+0x18/0x1c) r6:c02bc638 r5:00000106 r4:c79f5d18 r3:00000000 [<c0236e34>] (dump_stack+0x0/0x1c) from [<c0025e6c>] (warn_slowpath_common+0x54/0x6c) [<c0025e18>] (warn_slowpath_common+0x0/0x6c) from [<c0025f28>] (warn_slowpath_fmt+0x38/0x40) r8:20000013 r7:c780c6f0 r6:c031613c r5:c780c6f0 r4:c02b1b29 r3:00000009 [<c0025ef0>] (warn_slowpath_fmt+0x0/0x40) from [<c015eb4c>] (debug_print_object+0x9c/0xc8) r3:c02b1b29 r2:c02bc662 [<c015eab0>] (debug_print_object+0x0/0xc8) from [<c015f574>] (debug_check_no_obj_freed+0xac/0x1dc) r6:c7964000 r5:00000001 r4:c7964000 [<c015f4c8>] (debug_check_no_obj_freed+0x0/0x1dc) from [<c00a9e38>] (kmem_cache_free+0x88/0x1f8) [<c00a9db0>] (kmem_cache_free+0x0/0x1f8) from [<c014286c>] (blk_release_queue+0x70/0x78) [<c01427fc>] (blk_release_queue+0x0/0x78) from [<c015290c>] (kobject_release+0x70/0x84) r5:c79641f0 r4:c796420c [<c015289c>] (kobject_release+0x0/0x84) from [<c0153ce4>] (kref_put+0x68/0x80) r7:00000083 r6:c74083d0 r5:c015289c r4:c796420c [<c0153c7c>] (kref_put+0x0/0x80) from [<c01527d0>] (kobject_put+0x48/0x5c) r5:c79643b4 r4:c79641f0 [<c0152788>] (kobject_put+0x0/0x5c) from [<c013ddd8>] (blk_cleanup_queue+0x68/0x74) r4:c7964000 [<c013dd70>] (blk_cleanup_queue+0x0/0x74) from [<c01a6370>] (mmc_blk_put+0x78/0xe8) r5:00000000 r4:c794c400 [<c01a62f8>] (mmc_blk_put+0x0/0xe8) from [<c01a64b4>] (mmc_blk_release+0x24/0x38) r5:c794c400 r4:c0322824 [<c01a6490>] (mmc_blk_release+0x0/0x38) from [<c00de11c>] (__blkdev_put+0xe8/0x170) r5:c78d5e00 r4:c74083c0 [<c00de034>] (__blkdev_put+0x0/0x170) from [<c00de2c0>] (blkdev_put+0x11c/0x12c) r8:c79f5f70 r7:00000001 r6:c74083d0 r5:00000083 r4:c74083c0 r3:00000000 [<c00de1a4>] (blkdev_put+0x0/0x12c) from [<c00b0724>] (kill_block_super+0x60/0x6c) r7:c7942300 r6:c79f4000 r5:00000083 r4:c74083c0 [<c00b06c4>] (kill_block_super+0x0/0x6c) from [<c00b0a94>] (deactivate_locked_super+0x44/0x70) r6:c79f4000 r5:c031af64 r4:c794dc00 r3:c00b06c4 [<c00b0a50>] (deactivate_locked_super+0x0/0x70) from [<c00b1358>] (deactivate_super+0x6c/0x70) r5:c794dc00 r4:c794dc00 [<c00b12ec>] (deactivate_super+0x0/0x70) from [<c00c88b0>] (mntput_no_expire+0x188/0x194) r5:c794dc00 r4:c7942300 [<c00c8728>] (mntput_no_expire+0x0/0x194) from [<c00c95e0>] (sys_umount+0x2e4/0x310) r6:c7942300 r5:00000000 r4:00000000 r3:00000000 [<c00c92fc>] (sys_umount+0x0/0x310) from [<c000d940>] (ret_fast_syscall+0x0/0x30) ---[ end trace e5c83c92ada51c76 ]--- Signed-off-by:

commit d715e433 upstream. kdump fails because we try to execute an HV only instruction. Feature fixups are being applied after we copy the exception vectors down to 0 so they miss out on any updates. We have always had this issue but it only became critical in v3.0 when we added CFAR support (breaks POWER5) and v3.1 when we added POWERNV (breaks everyone). Signed-off-by:

commit 72f3bea0 upstream. Fixes the PS3 bootup hang introduced in 3.0-rc1 by: commit 317f3941 sched: Move the second half of ttwu() to the remote cpu Move the PS3's LV1 EOI call lv1_end_of_interrupt_ext() from ps3_chip_eoi() to ps3_get_irq() for IPI messages. If lv1_send_event_locally() is called between a previous call to lv1_send_event_locally() and the coresponding call to lv1_end_of_interrupt_ext() the second event will not be delivered to the target cpu. The PS3's SMP IPIs are implemented using lv1_send_event_locally(), so if two IPI messages of the same type are sent to the same target in a relatively short period of time the second IPI event can become lost when lv1_end_of_interrupt_ext() is called from ps3_chip_eoi().

commit 99cb2ddc upstream. gref->gref_id is unsigned so the error handling didn't work. gnttab_grant_foreign_access() returns an int type, so we can add a cast here, and it doesn't cause any problems. gnttab_grant_foreign_access() can return a variety of errors including -ENOSPC, -ENOSYS and -ENOMEM.

commit 21643e69 upstream. On 32 bit systems a high value of op.count could lead to an integer overflow in the kzalloc() and gref_ids would be smaller than expected. If the you triggered another integer overflow in "if (gref_size + op.count > limit)" then you'd probably get memory corruption inside add_grefs(). Signed-off-by:

commit f09ee045 upstream. The codec for Devkit8000 (TWL4030) was not detected except when build with CONFIG_SND_SOC_ALL_CODECS. twl-core.c still uses the CONFIG_TWL4030_CODEC for twl_has_codec(). In commit 57fe7251 the CONFIG_TWL4030_CODEC was renamed into CONFIG_MFD_TWL4030_AUDIO, thatswhy the codec was not detected. This patch renames the CONFIG_ TWL4030_CODEC into CONFIG_MFD_TWL4030_AUDIO in twl-core.c. Signed-off-by:

commit dcaaf9f2 upstream. In the recent usb-audio driver, the initialization of volume ranges may be delayed when the device doesn't respond well at the probing time. But the volume quirks for certain devices are applied only in mixer_ctl_feature_info() thus only at the very first probe and will be missing when the volume range is initialized later. This patch moves the volume quirk code to be always called from the volume-range extraction (get_min_max()), so that the quirks are properly applied in the later init time. Reported-and-tested-by:

commit 72103bd1 upstream. Commit 31a3ddda introduced a use after free in virtio-pci. The main issue is that the release method signals removal of the virtio device, while remove signals removal of the pci device. For example, on driver removal or hot-unplug, virtio_pci_release_dev is called before virtio_pci_remove. We then might get a crash as virtio_pci_remove tries to use the device freed by virtio_pci_release_dev. We allocate/free all resources together with the pci device, so we can leave the release method empty. Signed-off-by:

commit aeb4b88e upstream. When a virtual mater control is created, the driver looks for slave elements from the assigned card instance. But this may include the elements of other codecs when multiple codecs are on the same HD-audio bus. This works at the first time, but it'll give Oops when it's once freed and re-created via reconfig sysfs. This patch changes the element-look-up strategy to limit only to the mixer elements of the same codec. Reported-by:

commit 21404b77 upstream. This removes the use of the special "macbookair_fn_keys" keyboard translation table for the MacBookAir4,x models (ie the 2011 refresh). They use the standard apple_fn_keys[] translation. Apparently only the old MacBook Air's need a different translation table. This mirrors the change that commit da617c7c ("HID: consolidate MacbookAir 4,1 mappings") did for the WELLSPRING6A ones, but does it for the WELLSPRING6 model used on the MacBookAir4,2.

In nand_do_write_ops() code it is possible for a caller to provide ops.oobbuf populated and ops.mode == MTD_OOB_AUTO, which currently means that the chip->oob_poi buffer isn't initialised to all 0xFF. The nand_fill_oob() method then carries out the task of copying the provided OOB data to oob_poi, but with MTD_OOB_AUTO it skips areas marked as unavailable by the layout struct, including the bad block marker bytes. An example of this causing issues is when the last OOB data read was from the start of a bad block where the markers are not 0xFF, and the caller wishes to write new OOB data at the beginning of another block. In this scenario the caller would provide OOB data, but nand_fill_oob() would skip the bad block marker bytes in oob_poi before copying the OOB data provided by the caller. This means that when the OOB data is written back to NAND, the block is inadvertently marked as bad without the caller knowing. This has been witnessed when using YAFFS2 where tags are stored in the OOB. To avoid this oob_poi is always initialised to 0xFF to make sure no left over data is inadvertently written back to the OOB area.

commit 257a4b42 upstream. All updates that occur under STRIPE_ACTIVE should be globally visible when STRIPE_ACTIVE clears. test_and_set_bit() implies a barrier, but clear_bit() does not. This is suitable for 3.1-stable. Signed-off-by:

commit 9a3f530f upstream. When the number of failed devices exceeds the allowed number we must abort any active parity operations (checks or updates) as they are no longer meaningful, and can lead to a BUG_ON in handle_parity_checks6. This bug was introduce by commit 6c0069c0 in 2.6.29. Reported-by:

commit 52d6d4ef upstream. My recent commits (3782c69d, 324c74ad) introduced regression for register offset selection that based on the macversion. Not using parentheses in proper manner for ternary operator leads to select wrong offset for the registers. This issue was observed with AR9462 chip that immediate disconnect after the association with the following message ieee80211 phy3: wlan0: Failed to send nullfunc to AP 00:23:69:12:ea:47 after 500ms, disconnecting.

commit f5ff7cd1 upstream. The previous commit enforces a new rule for handling the cloned packets for transmit time stamping. These packets must not be freed using any other function than skb_complete_tx_timestamp. This commit fixes the one and only driver using this API. The driver first appeared in v3.0. Signed-off-by:

commit b2bac6ac upstream. As cryptd is depeneded on by other algorithms such as aesni-intel, it needs to be registered before them. When everything is built as modules, this occurs naturally. However, for this to work when they are built-in, we need to use subsys_initcall in cryptd. Tested-by:
