2020-07-30drm/amd/display: Clear dm_state for fast updatesMazin Rezk
This patch fixes a race condition that causes a use-after-free during amdgpu_dm_atomic_commit_tail. This can occur when 2 non-blocking commits are requested and the second one finishes before the first. Essentially, this bug occurs when the following sequence of events happens: 1. Non-blocking commit #1 is requested w/ a new dm_state #1 and is deferred to the workqueue. 2. Non-blocking commit #2 is requested w/ a new dm_state #2 and is deferred to the workqueue. 3. Commit #2 starts before commit #1, dm_state #1 is used in the commit_tail and commit #2 completes, freeing dm_state #1. 4. Commit #1 starts after commit #2 completes, uses the freed dm_state 1 and dereferences a freelist pointer while setting the context. Since this bug has only been spotted with fast commits, this patch fixes the bug by clearing the dm_state instead of using the old dc_state for fast updates. In addition, since dm_state is only used for its dc_state and amdgpu_dm_atomic_commit_tail will retain the dc_state if none is found, removing the dm_state should not have any consequences in fast updates. This use-after-free bug has existed for a while now, but only caused a noticeable issue starting from 5.7-rc1 due to 3202fa62f ("slub: relocate freelist pointer to middle of object") moving the freelist pointer from dm_state->base (which was unused) to dm_state->context (which is dereferenced).

2020-07-14drm/amd/display: Allow for vblank enabled with no active planesNicholas Kazlauskas
[Why] CRC capture doesn't work when the active plane count is 0 since we currently tie both vblank and pageflip interrupts to active_plane_count greater than 0. [How] The frontend is what generates the vblank interrupts while the backend is what generates pageflip interrupts. Both have a requirement for the CRTC to be active, so control the overall interrupt state based on that instead. Pageflip interrupts need to be enabled based on active plane count, but we actually rely on power gating to take care of disabling the interrupt for us on pipes that can be power gated. For pipes that can't be power gated it's still fine to leave it enabled since the interrupt only triggers after the address has been written to that particular pipe - which we won't be doing without an active plane. The issue we had before with this setup was that we couldn't force the state back on. We were essentially manipulating the refcount to enable or disable as needed in a two pass approach. However, there is a function that solves this problem more elegantly: amdgpu_irq_update() will unconditionally call the set based on what it thinks the current enablement state is. This leaves two future TODO items for our IRQ handling: - Disabling IRQs in commit tail instead of atomic commit - Mapping the pageflip interrupt to VUPDATE or something that's tied to the frontend instead of the backend since the mapping to CRTC is not correct Signed-off-by: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com> Reviewed-by: Bhawanpreet Lakha <Bhawanpreet.Lakha@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
