[ Upstream commit 58ac323084ebf44f8470eeb8b82660f9d0ee3689 ] Stale && dirty keys can be produced in the follow way: After writeback in write_dirty_finish(), dirty keys k1 will replace by clean keys k2 ==>ret = bch_btree_insert(dc->disk.c, &keys, NULL, &w->key); ==>btree_insert_fn(struct btree_op *b_op, struct btree *b) ==>static int bch_btree_insert_node(struct btree *b, struct btree_op *op, struct keylist *insert_keys, atomic_t *journal_ref, Then two steps: A) update k1 to k2 in btree node memory; bch_btree_insert_keys(b, op, insert_keys, replace_key) B) Write the bset(contains k2) to cache disk by a 30s delay work bch_btree_leaf_dirty(b, journal_ref). But before the 30s delay work write the bset to cache device, these things happened: A) GC works, and reclaim the bucket k2 point to; B) Allocator works, and invalidate the bucket k2 point to, and increase the gen of the bucket, and place it into free_inc fifo; C) Until now, the 30s delay work still does not finish work, so in the disk, the key still is k1, it is dirty and stale (its gen is smaller than the gen of the bucket). and then the machine power off suddenly happens; D) When the machine power on again, after the btree reconstruction, the stale dirty key appear. In bch_extent_bad(), when expensive_debug_checks is off, it would treat the dirty key as good even it is stale keys, and it would cause bellow probelms: A) In read_dirty() it would cause machine crash: BUG_ON(ptr_stale(dc->disk.c, &w->key, 0)); B) It could be worse when reads hits stale dirty keys, it would read old incorrect data. This patch tolerate the existence of these stale && dirty keys, and treat them as bad key in bch_extent_bad().

[ Upstream commit 149d0efada7777ad5a5242b095692af142f533d8 ] In extents.c:bch_extent_bad(), number 96 is used as parameter to call btree_bug_on(). The purpose is to check whether stale gen value exceeds BUCKET_GC_GEN_MAX, so it is better to use macro BUCKET_GC_GEN_MAX to make the code more understandable.

[ Upstream commit ed20151a7699bb2c77eba3610199789a126940c4 ] On i965gm we need to adjust max_vblank_count dynamically depending on whether the TV encoder is used or not. To that end add a per-crtc max_vblank_count that takes precedence over its device wide counterpart. The driver can now call drm_crtc_set_max_vblank_count() to configure the per-crtc value before calling drm_vblank_on(). Also looks like there was some discussion about exynos needing similar treatment. v2: Drop the extra max_vblank_count!=0 check for the WARN(last!=current), will take care of it in i915 code (Daniel) WARN_ON(!inmodeset) (Daniel) WARN_ON(dev->max_vblank_count) Pimp up the docs (Daniel) Cc: stable@vger.kernel.org Cc: Inki Dae <inki.dae@samsung.com> Cc: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181127182004.28885-1-ville.syrjala@linux.intel.comReviewed-by: NDaniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: NSasha Levin <sashal@kernel.org>

[ Upstream commit 1358c13a48c43f5e4de0c1835291837a27b9720c ] We were enabling autosuspend, which is using data set by the hash module, prior to the hash module being inited, casuing a crash on resume as part of the startup sequence if the race was lost. This was never a real problem because the PM infra was using low res timers so we were always winning the race, until commit 8234f6734c5d ("PM-runtime: Switch autosuspend over to using hrtimers") changed that :-) Fix this by seperating the PM setup and enablement and doing the latter only at the end of the init sequence.

[ Upstream commit 425784aa5b029eeb80498c73a68f62c3ad1d3b3f ] The async_file might be freed before the disassociation has been ended, causing qp shutdown to use after free on it. Since uverbs_destroy_ufile_hw is not a fence, it returns if a disassociation is ongoing in another thread. It has to be written this way to avoid deadlock. However this means that the ufile FD close cannot destroy anything that may still be used by an active kref, such as the the async_file. To fix that move the kref_put() to be in ib_uverbs_release_file().

Otherwise, if two filehandles are streaming at the same time, then closing the first will cancel the work which might still be running for a job from the second filehandle. As a result the second filehandle will never be able to finish the job and an attempt to stop streaming on that second filehandle will stall.

[ Upstream commit 1b3922a8bc74231f9a767d1be6d9a061a4d4eeab ] [BUG] Linux v5.0-rc1 will fail fstests/btrfs/163 with the following kernel message: BTRFS error (device dm-6): dev extent devid 1 physical offset 13631488 len 8388608 is beyond device boundary 0 BTRFS error (device dm-6): failed to verify dev extents against chunks: -117 BTRFS error (device dm-6): open_ctree failed [CAUSE] Commit cf90d884 ("btrfs: Introduce mount time chunk <-> dev extent mapping check") introduced strict check on dev extents. We use btrfs_find_device() with dev uuid and fs uuid set to NULL, and only dependent on @devid to find the real device. For seed devices, we call clone_fs_devices() in open_seed_devices() to allow us search seed devices directly. However clone_fs_devices() just populates devices with devid and dev uuid, without populating other essential members, like disk_total_bytes. This makes any device returned by btrfs_find_device(fs_info, devid, NULL, NULL) is just a dummy, with 0 disk_total_bytes, and any dev extents on the seed device will not pass the device boundary check. [FIX] This patch will try to verify the device returned by btrfs_find_device() and if it's a dummy then re-search in seed devices.

The reason this case is valid is due to find_lock_delalloc_range returning any available range after the passed delalloc_start and ignoring whether the page under writeback is within that range. In turn ordered extents (OE) are always created for the returned range from find_lock_delalloc_range. If, however, a failure occurs while OE are being created then the clean up code in btrfs_cleanup_ordered_extents will be called. Unfortunately the code in btrfs_cleanup_ordered_extents doesn't consider the case of such 'foreign' range being processed and instead it always assumes that the range OE are created for belongs to the page. This leads to the first page of such foregin range to not be cleaned up since it's deliberately missed and skipped by the current cleaning up code. Fix this by correctly checking whether the current page belongs to the range being instantiated and if so adjsut the range parameters passed for cleaning up. If it doesn't, then just clean the whole OE range directly.

[ Upstream commit a5fb11429167ee6ddeeacc554efaf5776b36433a ] When a transaction commit starts, it attempts to pause scrub and it blocks until the scrub is paused. So while the transaction is blocked waiting for scrub to pause, we can not do memory allocation with GFP_KERNEL from scrub, otherwise we risk getting into a deadlock with reclaim. Checking for scrub pause requests is done early at the beginning of the while loop of scrub_stripe() and later in the loop, scrub_extent() and scrub_raid56_parity() are called, which in turn call scrub_pages() and scrub_pages_for_parity() respectively. These last two functions do memory allocations using GFP_KERNEL. Same problem could happen while scrubbing the super blocks, since it calls scrub_pages(). We also can not have any of the worker tasks, created by the scrub task, doing GFP_KERNEL allocations, because before pausing, the scrub task waits for all the worker tasks to complete (also done at scrub_stripe()). So make sure GFP_NOFS is used for the memory allocations because at any time a scrub pause request can happen from another task that started to commit a transaction.

[ Upstream commit 234ff0b729ad882d20f7996591a964965647addf ] Testing has revealed an occasional crash which appears to be caused by a race between kvmppc_switch_mmu_to_hpt and kvm_unmap_hva_range_hv. The symptom is a NULL pointer dereference in __find_linux_pte() called from kvm_unmap_radix() with kvm->arch.pgtable == NULL. Looking at kvmppc_switch_mmu_to_hpt(), it does indeed clear kvm->arch.pgtable (via kvmppc_free_radix()) before setting kvm->arch.radix to NULL, and there is nothing to prevent kvm_unmap_hva_range_hv() or the other MMU callback functions from being called concurrently with kvmppc_switch_mmu_to_hpt() or kvmppc_switch_mmu_to_radix(). This patch therefore adds calls to spin_lock/unlock on the kvm->mmu_lock around the assignments to kvm->arch.radix, and makes sure that the partition-scoped radix tree or HPT is only freed after changing kvm->arch.radix. This also takes the kvm->mmu_lock in kvmppc_rmap_reset() to make sure that the clearing of each rmap array (one per memslot) doesn't happen concurrently with use of the array in the kvm_unmap_hva_range_hv() or the other MMU callbacks.

[ Upstream commit 104f708fd1241b22f808bdf066ab67dc5a051de5 ] Until the vfio-ap driver came into live there was a well known agreement about the way how ap devices are initialized and their states when the driver's probe function is called. However, the vfio device driver when receiving an ap queue device does additional resets thereby removing the registration for interrupts for the ap device done by the ap bus core code. So when later the vfio driver releases the device and one of the default zcrypt drivers takes care of the device the interrupt registration needs to get renewed. The current code does no renew and result is that requests send into such a queue will never see a reply processed - the application hangs. This patch adds a function which resets the aq queue state machine for the ap queue device and triggers the walk through the initial states (which are reset and registration for interrupts). This function is now called before the driver's probe function is invoked. When the association between driver and device is released, the driver's remove function is called. The current implementation calls a ap queue function ap_queue_remove(). This invokation has been moved to the ap bus function to make the probe / remove pair for ap bus and drivers more symmetric.
