Author: Lionel Landwerlin <[email protected]> Date: Thu Jan 26 11:06:53 2017 +0000 anv: fix descriptor pool internal size allocation The size of the pool is slightly smaller than the size of the structure containing the whole pool. We need to take that into account on when setting up the internals. Fixes a crash due to out of bound memory access in: dEQP-VK.api.descriptor_pool.out_of_pool_memory v2: Drop debug traces (Lionel) Signed-off-by: Lionel Landwerlin <[email protected]> --- src/intel/vulkan/anv_descriptor_set.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/src/intel/vulkan/anv_descriptor_set.c b/src/intel/vulkan/anv_descriptor_set.c index a4b7638..7853ec7 100644 --- a/src/intel/vulkan/anv_descriptor_set.c +++ b/src/intel/vulkan/anv_descriptor_set.c @@ -329,18 +329,18 @@ VkResult anv_CreateDescriptorPool( } } - const size_t size = - sizeof(*pool) + + const size_t pool_size = pCreateInfo->maxSets * sizeof(struct anv_descriptor_set) + descriptor_count * sizeof(struct anv_descriptor) + buffer_count * sizeof(struct anv_buffer_view); + const size_t total_size = sizeof(*pool) + pool_size; - pool = vk_alloc2(&device->alloc, pAllocator, size, 8, + pool = vk_alloc2(&device->alloc, pAllocator, total_size, 8, VK_SYSTEM_ALLOCATION_SCOPE_OBJECT); if (!pool) return vk_error(VK_ERROR_OUT_OF_HOST_MEMORY); - pool->size = size; + pool->size = pool_size; pool->next = 0; pool->free_list = EMPTY; _______________________________________________ mesa-commit mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-commit
