commit 62496658 upstream. Mode setting in the TGA driver is broken for these reasons: - info->fix.line_length is set just once in tgafb_init_fix function. If we change videomode, info->fix.line_length is not recalculated - so the video mode is changed but the screen is corrupted because of wrong info->fix.line_length. - info->fix.smem_len is set in tgafb_init_fix to the size of the default video mode (640x480). If we set a higher resolution, info->fix.smem_len is smaller than the current screen size, preventing the userspace program from mapping the framebuffer. This patch fixes it: - info->fix.line_length initialization is moved to tgafb_set_par so that it is recalculated with each mode change. - info->fix.smem_len is set to a fixed value representing the real amount of video ram (the values are taken from xfree86 driver). - add a check to tgafb_check_var to prevent us from setting a videomode that doesn't fit into videoram. - in tgafb_register, tgafb_init_fix is moved upwards, to be called before fb_find_mode (because fb_find_mode already needs the videoram size set in tgafb_init_fix).

commit ad36d282 upstream. Added the functions task_ppid_nr_ns() and task_ppid_nr() to abstract the lookup of the PPID (real_parent's pid_t) of a process, including rcu locking, in the arbitrary and init_pid_ns. This provides an alternative to sys_getppid(), which is relative to the child process' pid namespace. (informed by ebiederman's 6c621b7e) Cc: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by:

commit 46a2986e upstream. We expect that all the Haswell series will need such quirks, sigh. The T431s seems to be T430 hardware in a T440s case, using the T440s touchpad, with the same min/max issue. The X1 Carbon 3rd generation name says 2nd while it is a 3rd generation. The X1 and T431s share a PnPID with the T540p, but the reported ranges are closer to those of the T440s. HdG: Squashed 5 quirk patches into one. T431s + L440 + L540 are written by me, S1 Yoga and X1 are written by Benjamin Tissoires. Hdg: Standardized S1 Yoga and X1 values, Yoga uses the same touchpad as the X240, X1 uses the same touchpad as the T440. Signed-off-by:

commit e39435ce upstream. I got a bug report yesterday from Laszlo Ersek in which he states that his kvm instance fails to suspend. Laszlo bisected it down to this commit 1cf7e9c6 ("virtio_blk: blk-mq support") where virtio-blk is converted to use the blk-mq infrastructure. After digging a bit, it became clear that the issue was with the queue drain. blk-mq tracks queue usage in a percpu counter, which is incremented on request alloc and decremented when the request is freed. The initial hunt was for an inconsistency in blk-mq, but everything seemed fine. In fact, the counter only returned crazy values when suspend was in progress. When a CPU is unplugged, the percpu counters merges that CPU state with the general state. blk-mq takes care to register a hotcpu notifier with the appropriate priority, so we know it runs after the percpu counter notifier. However, the percpu counter notifier only merges the state when the CPU is fully gone. This leaves a state transition where the CPU going away is no longer in the online mask, yet it still holds private values. This means that in this state, percpu_counter_sum() returns invalid results, and the suspend then hangs waiting for abs(dead-cpu-value) requests to complete which of course will never happen. Fix this by clearing the state earlier, so we never have a case where the CPU isn't in online mask but still holds private state. This bug has been there since forever, I guess we don't have a lot of users where percpu counters needs to be reliable during the suspend cycle. Signed-off-by:

commit fa8a53c3 upstream. As reported by Tang Chen, Gu Zheng and Yasuaki Isimatsu, the following issues exist in the aio ring page migration support. As a result, for example, we have the following problem: thread 1 | thread 2 | aio_migratepage() | |-> take ctx->completion_lock | |-> migrate_page_copy(new, old) | | *NOW*, ctx->ring_pages[idx] == old | | | *NOW*, ctx->ring_pages[idx] == old | aio_read_events_ring() | |-> ring = kmap_atomic(ctx->ring_pages[0]) | |-> ring->head = head; *HERE, write to the old ring page* | |-> kunmap_atomic(ring); | |-> ctx->ring_pages[idx] = new | | *BUT NOW*, the content of | | ring_pages[idx] is old. | |-> release ctx->completion_lock | As above, the new ring page will not be updated. Fix this issue, as well as prevent races in aio_ring_setup() by holding the ring_lock mutex during kioctx setup and page migration. This avoids the overhead of taking another spinlock in aio_read_events_ring() as Tang's and Gu's original fix did, pushing the overhead into the migration code. Note that to handle the nesting of ring_lock inside of mmap_sem, the migratepage operation uses mutex_trylock(). Page migration is not a 100% critical operation in this case, so the ocassional failure can be tolerated. This issue was reported by Sasha Levin. Based on feedback from Linus, avoid the extra taking of ctx->completion_lock. Instead, make page migration fully serialised by mapping->private_lock, and have aio_free_ring() simply disconnect the kioctx from the mapping by calling put_aio_ring_file() before touching ctx->ring_pages[]. This simplifies the error handling logic in aio_migratepage(), and should improve robustness. v4: always do mutex_unlock() in cases when kioctx setup fails. Reported-by:

commit 5fc68a6c upstream. The code to handle any length SG lists calls edma_resume() even before edma_start() is called. This is incorrect because edma_resume() enables edma events on the channel after which CPU (in edma_start) cannot clear posted events by writing to ECR (per the EDMA user's guide). Because of this EDMA transfers fail to start if due to some reason there is a pending EDMA event registered even before EDMA transfers are started. This can happen if an EDMA event is a byproduct of device initialization. Fix this by calling edma_resume() only if it is not the first batch of MAX_NR_SG elements. Without this patch, MMC/SD fails to function on DA850 EVM with DMA. The behaviour is triggered by specific IP and this can explain why the issue was not reported before (example with MMC/SD on AM335x). Tested on DA850 EVM and AM335x EVM-SK using MMC/SD card.

commit a9d45396 upstream. The persistent-data library used by dm-thin, dm-cache, etc is transactional. If anything goes wrong, such as an io error when writing new metadata or a power failure, then we roll back to the last transaction. Atomicity when committing a transaction is achieved by: a) Never overwriting data from the previous transaction. b) Writing the superblock last, after all other metadata has hit the disk. This commit and the following commit ("dm: take care to copy the space map roots before locking the superblock") fix a bug associated with (b). When committing it was possible for the superblock to still be written in spite of an io error occurring during the preceeding metadata flush. With these commits we're careful not to take the write lock out on the superblock until after the metadata flush has completed. Change the transaction manager's semantics for dm_tm_commit() to assume all data has been flushed _before_ the single superblock that is passed in. As a prerequisite, split the block manager's block unlocking and flushing by simplifying dm_bm_flush_and_unlock() to dm_bm_flush(). Now the unlocking must be done separately. This issue was discovered by forcing io errors at the crucial time using dm-flakey. Signed-off-by:

commit d132cc6d upstream. If the discard block size is larger than the cache block size we will not properly quiesce IO to a region that is about to be discarded. This results in a race between a cache migration where no copy is needed, and a write to an adjacent cache block that's within the same large discard block. Workaround this by limiting the discard_block_size to cache_block_size. Also limit the max_discard_sectors to cache_block_size. A more comprehensive fix that introduces range locking support in the bio_prison and proper quiescing of a discard range that spans multiple cache blocks is already in development. Reported-by:

commit a585f87c upstream. The scenario here is that someone calls enable_irq_wake() from somewhere in the code. This will result in the lockdep producing a backtrace as can be seen below. In my case, this problem is triggered when using the wl1271 (TI WlCore) driver found in drivers/net/wireless/ti/ . The problem cause is rather obvious from the backtrace, but let's outline the dependency. enable_irq_wake() grabs the IRQ buslock in irq_set_irq_wake(), which in turns calls mxs_gpio_set_wake_irq() . But mxs_gpio_set_wake_irq() calls enable_irq_wake() again on the one-level-higher IRQ , thus it tries to grab the IRQ buslock again in irq_set_irq_wake() . Because the spinlock in irq_set_irq_wake()->irq_get_desc_buslock()->__irq_get_desc_lock() is not marked as recursive, lockdep will spew the stuff below. We know we can safely re-enter the lock, so use IRQ_GC_INIT_NESTED_LOCK to fix the spew. ============================================= [ INFO: possible recursive locking detected ] 3.10.33-00012-gf06b763-dirty #61 Not tainted --------------------------------------------- kworker/0:1/18 is trying to acquire lock: (&irq_desc_lock_class){-.-...}, at: [<c00685f0>] __irq_get_desc_lock+0x48/0x88 but task is already holding lock: (&irq_desc_lock_class){-.-...}, at: [<c00685f0>] __irq_get_desc_lock+0x48/0x88 other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(&irq_desc_lock_class); lock(&irq_desc_lock_class); *** DEADLOCK *** May be due to missing lock nesting notation 3 locks held by kworker/0:1/18: #0: (events){.+.+.+}, at: [<c0036308>] process_one_work+0x134/0x4a4 #1: ((&fw_work->work)){+.+.+.}, at: [<c0036308>] process_one_work+0x134/0x4a4 #2: (&irq_desc_lock_class){-.-...}, at: [<c00685f0>] __irq_get_desc_lock+0x48/0x88 stack backtrace: CPU: 0 PID: 18 Comm: kworker/0:1 Not tainted 3.10.33-00012-gf06b763-dirty #61 Workqueue: events request_firmware_work_func [<c0013eb4>] (unwind_backtrace+0x0/0xf0) from [<c0011c74>] (show_stack+0x10/0x14) [<c0011c74>] (show_stack+0x10/0x14) from [<c005bb08>] (__lock_acquire+0x140c/0x1a64) [<c005bb08>] (__lock_acquire+0x140c/0x1a64) from [<c005c6a8>] (lock_acquire+0x9c/0x104) [<c005c6a8>] (lock_acquire+0x9c/0x104) from [<c051d5a4>] (_raw_spin_lock_irqsave+0x44/0x58) [<c051d5a4>] (_raw_spin_lock_irqsave+0x44/0x58) from [<c00685f0>] (__irq_get_desc_lock+0x48/0x88) [<c00685f0>] (__irq_get_desc_lock+0x48/0x88) from [<c0068e78>] (irq_set_irq_wake+0x20/0xf4) [<c0068e78>] (irq_set_irq_wake+0x20/0xf4) from [<c027260c>] (mxs_gpio_set_wake_irq+0x1c/0x24) [<c027260c>] (mxs_gpio_set_wake_irq+0x1c/0x24) from [<c0068cf4>] (set_irq_wake_real+0x30/0x44) [<c0068cf4>] (set_irq_wake_real+0x30/0x44) from [<c0068ee4>] (irq_set_irq_wake+0x8c/0xf4) [<c0068ee4>] (irq_set_irq_wake+0x8c/0xf4) from [<c0310748>] (wlcore_nvs_cb+0x10c/0x97c) [<c0310748>] (wlcore_nvs_cb+0x10c/0x97c) from [<c02be5e8>] (request_firmware_work_func+0x38/0x58) [<c02be5e8>] (request_firmware_work_func+0x38/0x58) from [<c0036394>] (process_one_work+0x1c0/0x4a4) [<c0036394>] (process_one_work+0x1c0/0x4a4) from [<c0036a4c>] (worker_thread+0x138/0x394) [<c0036a4c>] (worker_thread+0x138/0x394) from [<c003cb74>] (kthread+0xa4/0xb0) [<c003cb74>] (kthread+0xa4/0xb0) from [<c000ee00>] (ret_from_fork+0x14/0x34) wlcore: loaded Signed-off-by:

commit 4991a628 upstream. A fl->fl_break_time of 0 has a special meaning to the lease break code that basically means "never break the lease". knfsd uses this to ensure that leases don't disappear out from under it. Unfortunately, the code in __break_lease can end up passing this value to wait_event_interruptible as a timeout, which prevents it from going to sleep at all. This causes __break_lease to spin in a tight loop and causes soft lockups. Fix this by ensuring that we pass a minimum value of 1 as a timeout instead. Cc: J.
