commit a6d65e451cc4e7127698384868a4447ee7be7d16 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Mon Oct 16 21:27:32 2017 +0100 drm/i915: Report -EFAULT before pwrite fast path into shmemfs When pwriting into shmemfs, the fast path pagecache_write does not notice when it is writing to beyond the end of the truncated shmemfs inode. Report -EFAULT directly when we try to use pwrite into the !I915_MADV_WILLNEED object. Fixes: 7c55e2c5772d ("drm/i915: Use pagecache write to prepopulate shmemfs from pwrite-ioctl") Also, GLK-shards: (gem_madvise:1498) CRITICAL: Test assertion failure function dontneed_before_pwrite, file gem_madvise.c:122: (gem_madvise:1498) CRITICAL: Failed assertion: __gem_write(fd, handle, 0, &bbe, sizeof(bbe)) == -14 (gem_madvise:1498) CRITICAL: error: 0 != -14 Subtest dontneed-before-pwrite failed. https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3253/shard-glkb4/igt@gem_madvise@dontneed-before-pwrite.html From CI_DRM_3254 this issue is no longer reproducible. |
