2022-10-20drbd: only clone bio if we have a backing deviceChristoph Böhmwalder1-8/+6
Commit c347a787e34cb (drbd: set ->bi_bdev in drbd_req_new) moved a bio_set_dev call (which has since been removed) to "earlier", from drbd_request_prepare to drbd_req_new. The problem is that this accesses device->ldev->backing_bdev, which is not NULL-checked at this point. When we don't have an ldev (i.e. when the DRBD device is diskless), this leads to a null pointer deref. So, only allocate the private_bio if we actually have a disk. This is also a small optimization, since we don't clone the bio to only to immediately free it again in the diskless case.

2022-10-20drm/panfrost: replace endian-specific types with native onesSteven Price1-18/+18
__le32 and __le64 types aren't portable and are not available on FreeBSD (which uses the same uAPI). Instead of attempting to always output little endian, just use native endianness in the dumps. Tools can detect the endianness in use by looking at the 'magic' field, but equally we don't expect big-endian to be used with Mali (there are no known implementations out there).

2022-10-20drm/connector: Set DDC pointer in drmm_connector_initMaxime Ripard1-1/+1
Commit 35a3b82f1bdd ("drm/connector: Introduce drmm_connector_init") introduced the function drmm_connector_init() with a parameter for an optional ddc pointer to the i2c controller used to access the DDC bus. However, the underlying call to __drm_connector_init() was always setting it to NULL instead of passing the ddc argument around. This resulted in unexpected null pointer dereference on platforms expecting to get a DDC controller.

2022-10-20drm: tests: Fix a buffer overflow in format_helper_testDavid Gow1-1/+1
The xrgb2101010 format conversion test (unlike for other formats) does an endianness conversion on the results. However, it always converts TEST_BUF_SIZE 32-bit integers, which results in reading from (and writing to) more memory than in present in the result buffer.

2022-10-19nvme-hwmon: kmalloc the NVME SMART log bufferSerge Semin1-7/+16
Recent commit 52fde2c07da6 ("nvme: set dma alignment to dword") has caused a regression on our platform. It turned out that the nvme_get_log() method invocation caused the nvme_hwmon_data structure instance corruption. In particular the nvme_hwmon_data.ctrl pointer was overwritten either with zeros or with garbage. After some research we discovered that the problem happened even before the actual NVME DMA execution, but during the buffer mapping. Since our platform is DMA-noncoherent, the mapping implied the cache-line invalidations or write-backs depending on the DMA-direction parameter. In case of the NVME SMART log getting the DMA was performed from-device-to-memory, thus the cache-invalidation was activated during the buffer mapping. Since the log-buffer isn't cache-line aligned, the cache-invalidation caused the neighbour data to be discarded. The neighbouring data turned to be the data surrounding the buffer in the framework of the nvme_hwmon_data structure. In order to fix that we need to make sure that the whole log-buffer is defined within the cache-line-aligned memory region so the cache-invalidation procedure wouldn't involve the adjacent data. One of the option to guarantee that is to kmalloc the DMA-buffer [1]. Seeing the rest of the NVME core driver prefer that method it has been chosen to fix this problem too. Note after a deeper researches we found out that the denoted commit wasn't a root cause of the problem. It just revealed the invalidity by activating the DMA-based NVME SMART log getting performed in the framework of the NVME hwmon driver. The problem was here since the initial commit of the driver.

2022-10-18drm/amdkfd: Fix type of reset_type parameter in hqd_destroy() callbackNathan Chancellor1-2/+3
When booting a kernel compiled with CONFIG_CFI_CLANG on a machine with an RX 6700 XT, there is a CFI failure in kfd_destroy_mqd_cp(): [ 12.894543] CFI failure at kfd_destroy_mqd_cp+0x2a/0x40 [amdgpu] (target: hqd_destroy_v10_3+0x0/0x260 [amdgpu]; expected type: 0x8594d794) Clang's kernel Control Flow Integrity (kCFI) makes sure that all indirect call targets have a type that exactly matches the function pointer prototype. In this case, hqd_destroy()'s third parameter, reset_type, should have a type of 'uint32_t' but every implementation of this callback has a third parameter type of 'enum kfd_preempt_type'. Update the function pointer prototype to match reality so that there is no more CFI violation.

Building 32-bit images may fail with the following error. drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_util_32.c: In function ‘dml32_UseMinimumDCFCLK’: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_util_32.c:3142:1: error: the frame size of 1096 bytes is larger than 1024 bytes This is seen when building i386:allmodconfig with any of the following compilers. gcc (Debian 12.2.0-3) 12.2.0 gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0 The problem is not seen if the compiler supports GCC_PLUGIN_LATENT_ENTROPY because in that case CONFIG_FRAME_WARN is already set to 2048 even for 32-bit builds. dml32_UseMinimumDCFCLK() was introduced with commit dda4fb85e433 ("drm/amd/display: DML changes for DCN32/321"). It declares a large number of local variables. Increase the frame size for the affected file to 2048, similar to other files in the same directory, to enable 32-bit build tests with affected compilers.
