Subject: [PATCH v2 0/4] drm/xe: Fix resource leaks in bo init and dma-buf paths
Date: Wed, 8 Apr 2026 17:52:51 +0000 [thread overview]
Message-ID: <20260408175255.3402838-1-shuicheng.lin@intel.com> (raw)
Fix several resource leaks in the xe driver's buffer object
initialization and dma-buf import paths:
Patches 1-2 fix xe_bo_init_locked() where two early validation error
paths return without freeing a caller-provided bo, violating the
documented contract that bo is freed on failure.
Patch 3 fixes xe_dma_buf_init_obj() where the pre-allocated storage bo
is leaked when drm_gpuvm_resv_object_alloc() fails.
Patch 4 fixes xe_gem_prime_import() where the dma-buf attachment is
leaked when xe_dma_buf_init_obj() fails.
v2: Add comments in patch 3.
Shuicheng Lin (4):
drm/xe/bo: Fix bo leak on unaligned size validation in
xe_bo_init_locked()
drm/xe/bo: Fix bo leak on GGTT flag validation in xe_bo_init_locked()
drm/xe: Fix bo leak in xe_dma_buf_init_obj() on allocation failure
drm/xe: Fix dma-buf attachment leak in xe_gem_prime_import()
