2020-04-29drm/qxl: qxl_release use after freeVasily Averin4-11/+7
qxl_release should not be accesses after qxl_push_*_ring_release() calls: userspace driver can process submitted command quickly, move qxl_release into release_ring, generate interrupt and trigger garbage collector. It can lead to crashes in qxl driver or trigger memory corruption in some kmalloc-192 slab object Gerd Hoffmann proposes to swap the qxl_release_fence_buffer_objects() + qxl_push_{cursor,command}_ring_release() calls to close that race window. cc: stable@vger.kernel.org Fixes: f64122c1f6ad ("drm: add new QXL driver.

2020-04-29dm multipath: use updated MPATHF_QUEUE_IO on mapping for bio-based mpathGabriel Krisman Bertazi1-2/+4
When adding devices that don't have a scsi_dh on a BIO based multipath, I was able to consistently hit the warning below and lock-up the system. The problem is that __map_bio reads the flag before it potentially being modified by choose_pgpath, and ends up using the older value. The WARN_ON below is not trivially linked to the issue. It goes like this: The activate_path delayed_work is not initialized for non-scsi_dh devices, but we always set MPATHF_QUEUE_IO, asking for initialization. That is fine, since MPATHF_QUEUE_IO would be cleared in choose_pgpath. Nevertheless, only for BIO-based mpath, we cache the flag before calling choose_pgpath, and use the older version when deciding if we should initialize the path. Therefore, we end up trying to initialize the paths, and calling the non-initialized activate_path work.

2020-04-29Fix use after free in get_tree_bdev()David Howells1-1/+1
Commit 6fcf0c72e4b9, a fix to get_tree_bdev() put a missing blkdev_put() in the wrong place, before a warnf() that displays the bdev under consideration rather after it. This results in a silent lockup in printk("%pg") called via warnf() from get_tree_bdev() under some circumstances when there's a race with the blockdev being frozen. This can be caused by xfstests/tests/generic/085 in combination with Lukas Czerner's ext4 mount API conversion patchset. It looks like it ought to occur with other users of get_tree_bdev() such as XFS, but apparently doesn't. Fix this by switching the order of the lines.

2020-04-28drm/amd/display: Defer cursor update around VUPDATE for all ASICNicholas Kazlauskas1-14/+14
[Why] Fixes the following scenario: - Flip has been prepared sometime during the frame, update pending - Cursor update happens right when VUPDATE would happen - OPTC lock acquired, VUPDATE is blocked until next frame - Flip is delayed potentially infinitely With the igt@kms_cursor_legacy cursor-vs-flip-legacy test we can observe nearly *13* frames of delay for some flips on Navi. [How] Apply the Raven workaround generically. When close enough to VUPDATE block cursor updates from occurring from the dc_stream_set_cursor_* helpers. This could perhaps be a little smarter by checking if there were pending updates or flips earlier in the frame on the HUBP side before applying the delay, but this should be fine for now. This fixes the kms_cursor_legacy test.

2020-04-27drm/i915/selftests: Fix i915_address_space refcnt leakXiyu Yang1-4/+8
igt_ppgtt_pin_update() invokes i915_gem_context_get_vm_rcu(), which returns a reference of the i915_address_space object to "vm" with increased refcount. When igt_ppgtt_pin_update() returns, "vm" becomes invalid, so the refcount should be decreased to keep refcount balanced. The reference counting issue happens in two exception handling paths of igt_ppgtt_pin_update(). When i915_gem_object_create_internal() returns IS_ERR, the refcnt increased by i915_gem_context_get_vm_rcu() is not decreased, causing a refcnt leak. Fix this issue by jumping to "out_vm" label when i915_gem_object_create_internal() returns IS_ERR.

2020-04-27dma-buf: Fix SET_NAME ioctl uapiDaniel Vetter2-1/+8
The uapi is the same on 32 and 64 bit, but the number isn't. Everyone who botched this please re-read: https://www.kernel.org/doc/html/v5.4-preprc-cpu/ioctl/botching-up-ioctls.html Also, the type argument for the ioctl macros is for the type the void __user *arg pointer points at, which in this case would be the variable-sized char[] of a 0 terminated string. So this was botched in more than just the usual ways.
