cypto: mediatek - fix leaks in mtk_desc_ring_alloc

2020-10-29T08:07:02+00:00

[ Upstream commit 228d284aac61283cde508a925d666f854b57af63 ] In the init loop, if an error occurs in function 'dma_alloc_coherent', then goto the err_cleanup section, after run i--, in the array ring, the struct mtk_ring with index i will not be released, causing memory leaks Fixes: 785e5c616c849 ("crypto: mediatek - Add crypto driver support for some MediaTek chips") Cc: Ryder Lee Signed-off-by: Xiaoliang Pang Signed-off-by: Herbert Xu Signed-off-by: Sasha Levin

crypto: mediatek - Fix wrong return value in mtk_desc_ring_alloc()

2020-10-29T08:07:01+00:00

[ Upstream commit 8cbde6c6a6d2b1599ff90f932304aab7e32fce89 ] In case of memory allocation failure, a negative error code should be returned.

crypto: mediatek - fix error return code in mtk_crypto_probe()

2017-07-18T09:50:54+00:00

Propagate the return value of platform_get_irq on failure. Signed-off-by: Gustavo A. R. Silva Signed-off-by: Herbert Xu

crypto: mediatek - drop .owner field in mtk_crypto_driver

2017-06-19T06:11:50+00:00

Drop .owner field in mtk_crypto_driver, since platform_driver_register() will set it automatically. Signed-off-by: Geliang Tang Signed-off-by: Herbert Xu

crypto: mediatek - remove redundant clock setting

2017-06-10T04:04:37+00:00

This patch removes redundant clock setting for 'clk_ethif', which is the parent of 'clk_cryp'. Hence, we just need to handle its child. Signed-off-by: Ryder Lee Signed-off-by: Herbert Xu

crypto: mediatek - Use IPAD/OPAD constant

2017-05-23T04:52:09+00:00

This patch simply replace all occurrence of HMAC IPAD/OPAD value by their define. Signed-off-by: Corentin Labbe Reviewed-by: Matthias Brugger Signed-off-by: Herbert Xu

crypto: mediatek - make hardware operation flow more efficient

2017-03-16T09:58:57+00:00

This patch refines data structures, which are used to control engine's data path, to make it more efficient. Hence current change are: - gathers the broken pieces of structures 'mtk_aes_ct''mtk_aes_tfm' into struct mtk_aes_info hence avoiding additional DMA-mapping. - adds 'keymode' in struct mtk_aes_base_ctx. When .setkey() callback is called, we store keybit setting in keymode. Doing so, there is no need to check keylen second time in mtk_aes_info_init() / mtk_aes_gcm_info_init(). Besides, this patch also removes unused macro definitions and adds helper inline function to write security information(key, IV,...) to info->state.

crypto: mediatek - add mtk_aes_gcm_tag_verify()

2017-03-16T09:58:56+00:00

This patch adds mtk_aes_gcm_tag_verify() which is used to compare authenticated tag. Signed-off-by: Ryder Lee Signed-off-by: Herbert Xu

crypto: mediatek - fix error handling in mtk_aes_complete()

2017-03-16T09:58:55+00:00

This patch fixes how errors should be handled by mtk_aes_complete(). Signed-off-by: Ryder Lee Signed-off-by: Herbert Xu

crypto: mediatek - add queue_task tasklet

2017-03-16T09:58:54+00:00

This patch adds 'queue_task' to dequeue crypto requset. This will help to avoid directly calling mtk_aes_handle_queue() / mtk_sha_handle_queue() from done tasklet or error handler. In order to avoid confusion, the new code properly renames DMA completion "task" to "done_task". Signed-off-by: Ryder Lee Signed-off-by: Herbert Xu
