drm/amdkfd: Fix potential deallocation of previously deallocated memory.

2023-07-19T14:21:27+00:00

[ Upstream commit cabbdea1f1861098991768d7bbf5a49ed1608213 ] Pointer mqd_mem_obj can be deallocated in kfd_gtt_sa_allocate(). The function then returns non-zero value, which causes the second deallocation. Found by Linux Verification Center (linuxtesting.org) with SVACE.

drm/amdkfd: Get prange->offset after svm_range_vram_node_new

commit 8eeddc0d4200762063e1c66b9cc63afa7b24ebf0 upstream. During miration to vram prange->offset is valid after vram buffer is located, either use old one or allocate a new one. Move svm_range_vram_node_new before migrate for each vma to get valid prange->offset. v2: squash in warning fix Fixes: b4ee9606378b ("drm/amdkfd: Fix BO offset for multi-VMA page migration") Signed-off-by: Xiaogang Chen Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amdkfd: Fixed kfd_process cleanup on module exit.

[ Upstream commit 20bc9f76b6a2455c6b54b91ae7634f147f64987f ] Handle case when module is unloaded (kfd_exit) before a process space (mm_struct) is released. v2: Fixed potential race conditions by removing all kfd_process from the process table first, then working on releasing the resources. v3: Fixed loop element access / synchronization.

As soon as the mutex is unlocked, another thread can free the BO.

For some GPUs with more CUs, the original sibling_map[32] in struct crat_subtype_cache is not enough to save the cache information when create the VCRAT table, so skip filling the struct crat_subtype_cache info instead fill struct kfd_cache_properties directly to fix this problem.
