crypto: sun8i-ce - fix nents passed to dma_unmap_sg()

2025-08-15T10:05:01+00:00

[ Upstream commit b6cd3cfb5afe49952f8f6be947aeeca9ba0faebb ] In sun8i_ce_cipher_unprepare(), dma_unmap_sg() is incorrectly called with the number of entries returned by dma_map_sg(), rather than using the original number of entries passed when mapping the scatterlist. To fix this, stash the original number of entries passed to dma_map_sg() in the request context.

crypto: sun8i-ce - move fallback ahash_request to the end of the struct

2025-06-27T10:07:07+00:00

[ Upstream commit c822831b426307a6ca426621504d3c7f99765a39 ] 'struct ahash_request' has a flexible array at the end, so it must be the last member in a struct, to avoid overwriting other struct members. Therefore, move 'fallback_req' to the end of the 'sun8i_ce_hash_reqctx' struct.

crypto: sun8i-ss - do not use sg_dma_len before calling DMA functions

2025-06-27T10:07:06+00:00

[ Upstream commit 2dfc7cd74a5e062a5405560447517e7aab1c7341 ] When testing sun8i-ss with multi_v7_defconfig, all CBC algorithm fail crypto selftests. This is strange since on sunxi_defconfig, everything was ok. The problem was in the IV setup loop which never run because sg_dma_len was 0.

crypto: sun8i-ce-cipher - fix error handling in sun8i_ce_cipher_prepare()

2025-06-27T10:07:06+00:00

[ Upstream commit f31adc3e356f7350d4a4d68c98d3f60f2f6e26b3 ] Fix two DMA cleanup issues on the error path in sun8i_ce_cipher_prepare(): 1] If dma_map_sg() fails for areq->dst, the device driver would try to free DMA memory it has not allocated in the first place. To fix this, on the "theend_sgs" error path, call dma unmap only if the corresponding dma map was successful. 2] If the dma_map_single() call for the IV fails, the device driver would try to free an invalid DMA memory address on the "theend_iv" path: ------------[ cut here ]------------ DMA-API: sun8i-ce 1904000.crypto: device driver tries to free an invalid DMA memory address WARNING: CPU: 2 PID: 69 at kernel/dma/debug.c:968 check_unmap+0x123c/0x1b90 Modules linked in: skcipher_example(O+) CPU: 2 UID: 0 PID: 69 Comm: 1904000.crypto- Tainted: G O 6.15.0-rc3+ #24 PREEMPT Tainted: [O]=OOT_MODULE Hardware name: OrangePi Zero2 (DT) pc : check_unmap+0x123c/0x1b90 lr : check_unmap+0x123c/0x1b90 ...

crypto: sun8i-ss - Fix a test in sun8i_ss_setup_ivs()

[ Upstream commit 8fd91151ebcb21b3f2f2bf158ac6092192550b2b ] SS_ENCRYPTION is (0 << 7 = 0), so the test can never be true. Use a direct comparison to SS_ENCRYPTION instead. The same king of test is already done the same way in sun8i_ss_run_task().
