2021-01-18btrfs: don't clear ret in btrfs_start_dirty_block_groupsJosef Bacik
If we fail to update a block group item in the loop we'll break, however we'll do btrfs_run_delayed_refs and lose our error value in ret, and thus not clean up properly. Fix this by only running the delayed refs if there was no failure.

2021-01-18drm/i915: support two CSC module on gen11 and laterLee Shawn C
There are two CSC on pipeline on gen11 and later platform. User space application is allowed to enable CTM and RGB to YCbCr coversion at the same time now. v2: check csc capability in {}_color_check function. v3: can't support two CSC at the same time in {ivb,glk}_color_check.

This is because btrfs_backref_release_cache() will cycle through all of the cache->leaves nodes and free them up. However btrfs_backref_error_cleanup() freed the backref node with btrfs_backref_free_node(), which simply kfree()d the backref node without unlinking it from the cache. Change this to a btrfs_backref_drop_node(), which does the appropriate cleanup and removes the node from the cache->leaves list, so when we go to free the remaining cache we don't trip over items we've already dropped.

2021-01-18btrfs: don't get an EINTR during drop_snapshot for relocJosef Bacik
This was partially fixed by f3e3d9cc3525 ("btrfs: avoid possible signal interruption of btrfs_drop_snapshot() on relocation tree"), however it missed a spot when we restart a trans handle because we need to end the transaction. The fix is the same, simply use btrfs_join_transaction() instead of btrfs_start_transaction() when deleting reloc roots.

2021-01-18dma-buf: Add debug optionDaniel Vetter
We have too many people abusing the struct page they can get at but really shouldn't in importers. Aside from that the backing page might simply not exist (for dynamic p2p mappings) looking at it and using it e.g. for mmap can also wreak the page handling of the exporter completely. Importers really must go through the proper interface like dma_buf_mmap for everything. I'm semi-tempted to enforce this for dynamic importers since those really have no excuse at all to break the rules. Unfortuantely we can't store the right pointers somewhere safe to make sure we oops on something recognizable, so best is to just wrangle them a bit by flipping all the bits. At least on x86 kernel addresses have all their high bits sets and the struct page array is fairly low in the kernel mapping, so flipping all the bits gives us a very high pointer in userspace and hence excellent chances for an invalid dereference. v2: Add a note to the @map_dma_buf hook that exporters shouldn't do fancy caching tricks, which would blow up with this address scrambling trick here (Chris) Enable by default when CONFIG_DMA_API_DEBUG is enabled. v3: Only one copy of the mangle/unmangle code (Christian) v4: #ifdef, not #if (0day) v5: sg_table can also be an ERR_PTR (Chris, Christian) Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Sumit Semwal <sumit.semwal@linaro.org> Cc: "Christian König" <christian.koenig@amd.com> Cc: David Stevens <stevensd@chromium.org> Cc: linux-media@vger.kernel.org Cc: linaro-mm-sig@lists.linaro.org Link: https://patchwork.freedesktop.org/patch/msgid/20210115164739.3958206-1-daniel.vetter@ffwll.ch
2021-01-18drm/ttm: WARN_ON non-empty lru when disabling a resource managerDaniel Vetter
ttm_resource_manager->use_type is only used for runtime changes by vmwgfx. I think ideally we'd push this functionality into drivers - ttm itself does not provide any locking to guarantee this is safe, so the only way this can work at runtime is if the driver does provide additional guarantees. vwmgfx does that through the vmw_private->reservation_sem. Therefore supporting this feature in shared code feels a bit misplaced. As a first step add a WARN_ON to make sure the resource manager is empty. This is just to make sure I actually understand correctly what vmwgfx is doing, and to make sure an eventual subsequent refactor doesn't break anything. This check should also be useful for other drivers, to make sure they haven't leaked anything.

This isn't actually protecting anything becuase: - when running, ttm_resource_manager->use_type is protected through vmw_private->reservation_semaphore against concurrent execbuf or well anything else that might evict or reserve buffers - during suspend/resume there's nothing else running, hence vmw_pm_freeze and vmw_pm_restore do not need to take the same lock. - this also holds for the SVGA_REG_ENABLE register write Hence it is safe to just remove that spinlock.

Similar to commit 49b20dbf7497 ("drm/i915/gt: Perform an arbitration check before busywaiting"), also add a check prior to the busywait on gen8+, as we have now seen (because we added a selftest to add fault injection into the engine resets) the same engine reset failure leading to an indefinite wait on the ring-stop semaphore. So not a Tigerlake specific bug after all, though it still seems odd behaviour for the busywait as we do get the arbitration point elsewhere on a miss.

2021-01-18udf: fix the problem that the disc content is not displayedlianzhi chang
When the capacity of the disc is too large (assuming the 4.7G specification), the disc (UDF file system) will be burned multiple times in the windows (Multisession Usage). When the remaining capacity of the CD is less than 300M (estimated value, for reference only), open the CD in the Linux system, the content of the CD is displayed as blank (the kernel will say "No VRS found"). Windows can display the contents of the CD normally. Through analysis, in the "fs/udf/super.c": udf_check_vsd function, the actual value of VSD_MAX_SECTOR_OFFSET may be much larger than 0x800000. According to the current code logic, it is found that the type of sbi->s_session is "__s32", when the remaining capacity of the disc is less than 300M (take a set of test values: sector=3154903040, sbi->s_session=1540464, sb->s_blocksize_bits=11 ), the calculation result of "sbi->s_session << sb->s_blocksize_bits" will overflow. Therefore, it is necessary to convert the type of s_session to "loff_t" (when udf_check_vsd starts, assign a value to _sector, which is also converted in this way), so that the result will not overflow, and then the content of the disc can be displayed normally.

2021-01-18drm/i915: Check for rq->hwsp validity after acquiring RCU lockChris Wilson
Since we allow removing the timeline map at runtime, there is a risk that rq->hwsp points into a stale page. To control that risk, we hold the RCU read lock while reading *rq->hwsp, but we missed a couple of important barriers. First, the unpinning / removal of the timeline map must be after all RCU readers into that map are complete, i.e. after an rcu barrier (in this case courtesy of call_rcu()). Secondly, we must make sure that the rq->hwsp we are about to dereference under the RCU lock is valid. In this case, we make the rq->hwsp pointer safe during i915_request_retire() and so we know that rq->hwsp may become invalid only after the request has been signaled. Therefore is the request is not yet signaled when we acquire rq->hwsp under the RCU, we know that rq->hwsp will remain valid for the duration of the RCU read lock. This is a very small window that may lead to either considering the request not completed (causing a delay until the request is checked again, any wait for the request is not affected) or dereferencing an invalid pointer.

2021-01-18drm/vc4: Unify PCM card's driver_nameNicolas Saenz Julienne
User-space ALSA matches a card's driver name against an internal list of aliases in order to select the correct configuration for the system. When the driver name isn't defined, the match is performed against the card's name. With the introduction of RPi4 we now have two HDMI ports with two distinct audio cards. This is reflected in their names, making them different from previous RPi versions. With this, ALSA ultimately misses the board's configuration on RPi4. In order to avoid this, set "card->driver_name" to "vc4-hdmi" unanimously.
