crypto: cavium - fix dma_free_coherent() size

2026-03-04T12:19:33+00:00

[ Upstream commit 941676c30ba5b40a01bed92448f457ce62fd1f07 ] The size of the buffer in alloc_command_queues() is curr->size + CPT_NEXT_CHUNK_PTR_SIZE, so used that length for dma_free_coherent().

crypto: cavium - Fix an error handling path in cpt_ucode_load_fw()

2024-12-05T13:01:21+00:00

[ Upstream commit 572b7cf08403b6c67dfe0dc3e0f2efb42443254f ] If do_cpt_init() fails, a previous dma_alloc_coherent() call needs to be undone. Add the needed dma_free_coherent() before returning.

crypto: cavium - Fix the if condition to exit loop after timeout

2024-12-05T13:01:18+00:00

[ Upstream commit 53d91ca76b6c426c546542a44c78507b42008c9e ] The while loop breaks in the first run because of incorrect if condition. It also causes the statements after the if to appear dead. Fix this by changing the condition from if(timeout--) to if(!timeout--). This bug was reported by Coverity Scan. Report: CID 1600859: (#1 of 1): Logically dead code (DEADCODE) dead_error_line: Execution cannot reach this statement: udelay(30UL); Fixes: 9e2c7d99941d ("crypto: cavium - Add Support for Octeon-tx CPT Engine") Signed-off-by: Everest K.C.

crypto: cavium/nitrox - refactor deprecated strncpy

2023-09-20T05:15:29+00:00

`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We know `hw.partname` is supposed to be NUL-terminated by its later use with seq_printf: | nitrox_debugfs.c +25 | seq_printf(s, " Part Name: %s\n", ndev->hw.partname); Let's prefer a more robust and less ambiguous string interface. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on the destination buffer.

crypto: xts - drop xts_check_key()

2023-01-06T09:15:47+00:00

xts_check_key() is obsoleted by xts_verify_key(). Over time XTS crypto drivers adopted the newer xts_verify_key() variant, but xts_check_key() is still used by a number of drivers. Switch drivers to use the newer xts_verify_key() and make a couple of cleanups. This allows us to drop xts_check_key() completely and avoid redundancy.
