2019-04-11NFS: Forbid setting AF_INET6 to "struct sockaddr_in"->sin_family.Tetsuo Handa1-1/+2
syzbot is reporting uninitialized value at rpc_sockaddr2uaddr() [1]. This is because syzbot is setting AF_INET6 to "struct sockaddr_in"->sin_family (which is embedded into user-visible "struct nfs_mount_data" structure) despite nfs23_validate_mount_data() cannot pass sizeof(struct sockaddr_in6) bytes of AF_INET6 address to rpc_sockaddr2uaddr(). Since "struct nfs_mount_data" structure is user-visible, we can't change "struct nfs_mount_data" to use "struct sockaddr_storage". Therefore, assuming that everybody is using AF_INET family when passing address via "struct nfs_mount_data"->addr, reject if its sin_family is not AF_INET.

2019-04-11nvmet: fix discover log page when offsets are usedKeith Busch4-25/+58
The nvme target hadn't been taking the Get Log Page offset parameter into consideration, and so has been returning corrupted log pages when offsets are used. Since many tools, including nvme-cli, split the log request to 4k, we've been breaking discovery log responses when more than 3 subsystems exist. Fix the returned data by internally generating the entire discovery log page and copying only the requested bytes into the user buffer. The command log page offset type has been modified to a native __le64 to make it easier to extract the value from a command.

2019-04-11nvme-fc: correct csn initialization and increments on errorJames Smart1-5/+15
This patch fixes a long-standing bug that initialized the FC-NVME cmnd iu CSN value to 1. Early FC-NVME specs had the connection starting with CSN=1. By the time the spec reached approval, the language had changed to state a connection should start with CSN=0. This patch corrects the initialization value for FC-NVME connections. Additionally, in reviewing the transport, the CSN value is assigned to the new IU early in the start routine. It's possible that a later dma map request may fail, causing the command to never be sent to the controller. Change the location of the assignment so that it is immediately prior to calling the lldd. Add a comment block to explain the impacts if the lldd were to additionally fail sending the command.

commit 5b0d62108b46 ("mmc: sdhci-omap: Add platform specific reset callback") skips data resets during tuning operation. Because of this, a data error or data finish interrupt might still arrive after a command error has been handled and the mrq ended. This ends up with a "mmc0: Got data interrupt 0x00000002 even though no data operation was in progress" error message. Fix this by adding a platform specific callback for sdhci_irq.

2019-04-11drm/i915: Bump ready tasks ahead of busywaitsChris Wilson3-10/+52
Consider two tasks that are running in parallel on a pair of engines (vcs0, vcs1), but then must complete on a shared engine (rcs0). To maximise throughput, we want to run the first ready task on rcs0 (i.e. the first task that completes on either of vcs0 or vcs1). When using semaphores, however, we will instead queue onto rcs in submission order. To resolve this incorrect ordering, we want to re-evaluate the priority queue when each of the request is ready. Normally this happens because we only insert into the priority queue requests that are ready, but with semaphores we are inserting ahead of their readiness and to compensate we penalize those tasks with reduced priority (so that tasks that do not need to busywait should naturally be run first). However, given a series of tasks that each use semaphores, the queue degrades into submission fifo rather than readiness fifo, and so to counter this we give a small boost to semaphore users as their dependent tasks are completed (and so we no longer require any busywait prior to running the user task as they are then ready themselves). v2: Fixup irqsave for schedule_lock (Tvrtko) Testcase: igt/gem_exec_schedule/semaphore-codependency Signed-off-by: Chris Wilson <[email protected]> Cc: Tvrtko Ursulin <[email protected]> Cc: Dmitry Rogozhkin <[email protected]> Cc: Dmitry Ermilov <[email protected]> Reviewed-by: Tvrtko Ursulin <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2019-04-10drm: switch drm_fb_xrgb8888_to_rgb565_dstclip to accept __iomem dstGerd Hoffmann3-61/+64
Not all archs have the __io_virt() macro, so cirrus can't simply convert pointers that way. The drm format helpers have to use memcpy_toio() instead. This patch makes drm_fb_xrgb8888_to_rgb565_dstclip() accept a __iomem dst pointer and use memcpy_toio() instead of memcpy(). The helper function (drm_fb_xrgb8888_to_rgb565_line) has been changed to process a single scanline.

2019-04-10drm: switch drm_fb_memcpy_dstclip to accept __iomem dstGerd Hoffmann3-23/+27
Not all archs have the __io_virt() macro, so cirrus can't simply convert pointers that way. The drm format helpers have to use memcpy_toio() instead. This patch makes drm_fb_memcpy_dstclip() accept a __iomem dst pointer and use memcpy_toio() instead of memcpy(). With that separating out the memcpy loop into the drm_fb_memcpy_lines() helper isn't useful any more, so move the code back into the calling functins.

2019-04-10drm/amd/display: Pass plane caps into amdgpu_dm_plane_initNicholas Kazlauskas1-29/+34
[Why] When deciding to add properties or expose formats on DRM planes we should be querying the caps for the DC plane it's supposed to represent. [How] Pass plane caps down into plane initialization, refactoring overlay plane initialization to have the overlay plane be represented by the first overlay capable DC plane.

2019-04-10drm/amd/display: Clean up locking in dcn*_apply_ctx_for_surface()Leo Li2-21/+49
[Why] dcn*_disable_plane() doesn't unlock the pipe anymore, making the extra lock unnecessary. In addition - during full plane updates - all necessary pipes should be locked/unlocked together when modifying hubp to avoid tearing in pipesplit setups. [How] Remove redundant locks, and add function to lock all pipes. If an interdependent pipe update is required, lock down all pipes. Otherwise, lock only the top pipe for the updated pipe tree.

2019-04-10drm/amd/display: Recreate private_obj->state during S3 resumeLeo Li1-0/+7
[Why] When entering S3, amdgpu first calls DRM to cache the current atomic state, then commit the 'all-disabled' state. This sets dc->current_state to point at the private atomic object's dm_atomic_state->context, as any regular atomic commit would. Afterwards, amdgpu_dm calls dc_set_power_state() with S3 power state. This invalidates dc->current_state by wiping it to 0, consequently wiping dm_atomic_state->context. During resume, the cached atomic state is restored. When getting the private object however, the dm_atomic_state - containing the wiped context - is duplicated into the atomic state. This causes DC validation to fail during atomic check, as necessary function pointers in dc_state are now NULL. [How] Recreate the private object's dm_atomic_state->context during resume, restoring any static values such as function pointers. A TODO item is added to move static read-only values out of dc_state - they shouldn't be there anyways.

2019-04-10drm/amd/display: disable link before changing link settingsAnthony Koo1-0/+9
[Why] If link is already enabled at a different rate (for example 5.4 Gbps) then calling VBIOS command table to switch to a new rate (for example 2.7 Gbps) will not take effect. This can lead to link training failure to occur. [How] If the requested link rate is different than the current link rate, the link must be disabled in order to re-enable at the new link rate. In today's logic it is currently only impacting eDP since DP connection types will always disable the link during display detection, when initial link verification occurs.
