crypto: marvell/octeontx - fix DMA cleanup using wrong loop index

2026-07-24T14:19:50+00:00

[ Upstream commit 7891c64c0520519782470ba29bac8a5761e295d8 ] The sg_cleanup path used list[i] instead of list[j] when unmapping DMA buffers, leaking successfully mapped entries and repeatedly unmapping the failed one.

crypto: marvell/cesa - use memcpy_and_pad in mv_cesa_ahash_export

2026-03-27T09:52:25+00:00

Replace memset() followed by memcpy() with memcpy_and_pad() to simplify the code and to write to 'cache' only once. Signed-off-by: Thorsten Blum Signed-off-by: Herbert Xu

crypto: octeontx - Replace scnprintf with strscpy in print_ucode_info

2026-02-28T03:53:58+00:00

Replace scnprintf("%s", ...) with the faster and more direct strscpy(). Remove the parentheses while we're at it. Signed-off-by: Thorsten Blum Signed-off-by: Herbert Xu

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument

2026-02-22T01:09:51+00:00

This was done entirely with mindless brute force, using git grep -l '\

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

crypto: cesa - Simplify return statement in mv_cesa_dequeue_req_locked

2026-02-06T10:52:22+00:00

Return the result of calling crypto_dequeue_request() directly and remove the local return variable. Signed-off-by: Thorsten Blum Signed-off-by: Herbert Xu

crypto: octeontx - fix dma_free_coherent() size

2026-01-16T06:02:06+00:00

The size of the buffer in alloc_command_queues() is curr->size + OTX_CPT_NEXT_CHUNK_PTR_SIZE, so used that length for dma_free_coherent(). Fixes: 10b4f09491bf ("crypto: marvell - add the Virtual Function driver for CPT") Signed-off-by: Thomas Fourier Signed-off-by: Herbert Xu

crypto: octeontx2 - Use sysfs_emit in sysfs show functions

2025-12-29T00:48:35+00:00

Replace sprintf() with sysfs_emit() in sso_pf_func_ovrd_show() and kvf_limits_show(). sysfs_emit() is preferred for formatting sysfs output as it performs proper bounds checking. No functional changes. Signed-off-by: Thorsten Blum Signed-off-by: Herbert Xu

crypto: octeontx - Fix length check to avoid truncation in ucode_load_store

2025-12-19T06:47:47+00:00

OTX_CPT_UCODE_NAME_LENGTH limits the microcode name to 64 bytes. If a user writes a string of exactly 64 characters, the original code used 'strlen(buf) > 64' to check the length, but then strscpy() copies only 63 characters before adding a NUL terminator, silently truncating the copied string. Fix this off-by-one error by using 'count' directly for the length check to ensure long names are rejected early and copied without truncation.
