crypto: octeontx - fix dma_free_coherent() size

2026-03-04T12:19:31+00:00

[ Upstream commit 624a6760bf8464965c17c8df10b40b557eaa3002 ] 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().

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

2026-02-16T09:17:47+00:00

commit 5565a72b24fa7935a9f30af386e92c8c9dfb23b9 upstream. 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.

crypto: octeontx2 - add timeout for load_fvc completion poll

2025-08-28T14:28:27+00:00

[ Upstream commit 2157e50f65d2030f07ea27ef7ac4cfba772e98ac ] Adds timeout to exit from possible infinite loop, which polls on CPT instruction(load_fvc) completion. Signed-off-by: Srujana Challa Signed-off-by: Bharat Bhushan Signed-off-by: Herbert Xu Signed-off-by: Sasha Levin

crypto: marvell/cesa - Fix engine load inaccuracy

2025-08-15T10:08:51+00:00

[ Upstream commit 442134ab30e75b7229c4bfc1ac5641d245cffe27 ] If an error occurs during queueing the engine load will never be decremented. Fix this by moving the engine load adjustment into the cleanup function.

crypto: marvell/cesa - Do not chain submitted requests

2025-06-27T10:08:42+00:00

commit 0413bcf0fc460a68a2a7a8354aee833293d7d693 upstream. This driver tries to chain requests together before submitting them to hardware in order to reduce completion interrupts. However, it even extends chains that have already been submitted to hardware. This is dangerous because there is no way of knowing whether the hardware has already read the DMA memory in question or not. Fix this by splitting the chain list into two. One for submitted requests and one for requests that have not yet been submitted. Only extend the latter.

crypto: marvell/cesa - Avoid empty transfer descriptor

2025-06-19T13:28:03+00:00

[ Upstream commit 1bafd82d9a40cf09c6c40f1c09cc35b7050b1a9f ] The user may set req->src even if req->nbytes == 0. If there is no data to hash from req->src, do not generate an empty TDMA descriptor.

crypto: marvell/cesa - Handle zero-length skcipher requests

crypto: octeontx2 - suppress auth failure screaming due to negative tests

2025-06-04T12:41:59+00:00

[ Upstream commit 64b7871522a4cba99d092e1c849d6f9092868aaa ] This patch addresses an issue where authentication failures were being erroneously reported due to negative test failures in the "ccm(aes)" selftest. pr_debug suppress unnecessary screaming of these tests.

crypto: marvell/cesa - Disable hash algorithms

[ Upstream commit e845d2399a00f866f287e0cefbd4fc7d8ef0d2f7 ] Disable cesa hash algorithms by lowering the priority because they appear to be broken when invoked in parallel. This allows them to still be tested for debugging purposes. Reported-by: Klaus Kudielka Signed-off-by: Herbert Xu Signed-off-by: Sasha Levin
