| * accel/ivpu: refactor deprecated strncpyJustin Stitt2023-08-251-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `strncpy` is deprecated for use on NUL-terminated destination strings [1]. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on its destination buffer argument which is _not_ the case for `strncpy`! Also remove extraneous if-statement as it can never be entered. The return value from `strncpy` is it's first argument. In this case, `...dyndbg_cmd` is an array: | char dyndbg_cmd[VPU_DYNDBG_CMD_MAX_LEN]; ^^^^^^^^^^ This can never be NULL which means `strncpy`'s return value cannot be NULL here. Just use `strscpy` which is more robust and results in simpler and less ambiguous code. Moreover, remove needless `... - 1` as `strscpy`'s implementation ensures NUL-termination and we do not need to carefully dance around ending boundaries with a "- 1" anymore.

| | * accel/qaic: Clean up integer overflow checking in map_user_pages()Dan Carpenter2023-08-151-8/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The encode_dma() function has some validation on in_trans->size but it would be more clear to move those checks to find_and_map_user_pages(). The encode_dma() had two checks: if (in_trans->addr + in_trans->size < in_trans->addr || !in_trans->size) return -EINVAL; The in_trans->addr variable is the starting address. The in_trans->size variable is the total size of the transfer. The transfer can occur in parts and the resources->xferred_dma_size tracks how many bytes we have already transferred. This patch introduces a new variable "remaining" which represents the amount we want to transfer (in_trans->size) minus the amount we have already transferred (resources->xferred_dma_size). I have modified the check for if in_trans->size is zero to instead check if in_trans->size is less than resources->xferred_dma_size. If we have already transferred more bytes than in_trans->size then there are negative bytes remaining which doesn't make sense. If there are zero bytes remaining to be copied, just return success. The check in encode_dma() checked that "addr + size" could not overflow and barring a driver bug that should work, but it's easier to check if we do this in parts. First check that "in_trans->addr + resources->xferred_dma_size" is safe. Then check that "xfer_start_addr + remaining" is safe. My final concern was that we are dealing with u64 values but on 32bit systems the kmalloc() function will truncate the sizes to 32 bits. So I calculated "total = in_trans->size + offset_in_page(xfer_start_addr);" and returned -EINVAL if it were >= SIZE_MAX. This will not affect 64bit systems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When receiving sei interrupt from tpc or decoder, we need to check the binning mask because if the engine is binned, the razwi info won't be in the router of the binned engine, instead will be in the router of the substitute engine.
