crypto: qce - fix uaf on qce_skcipher_register_one

2021-11-20T04:02:08Z

Pointer alg points to sub field of tmpl, it is dereferenced after tmpl is freed. Fix this by accessing alg before free tmpl. Fixes: ec8f5d8f ("crypto: qce - Qualcomm crypto engine driver") Signed-off-by: Chengfeng Ye Acked-by: Thara Gopinath Signed-off-by: Herbert Xu

crypto: qce - fix error return code in qce_skcipher_async_req_handle()

2021-06-11T07:03:29Z

Fix to return a negative error code from the error handling case instead of 0, as done elsewhere in this function.

crypto: qce: skcipher: Fix incorrect sg count for dma transfers

2021-05-28T07:11:45Z

Use the sg count returned by dma_map_sg to call into dmaengine_prep_slave_sg rather than using the original sg count. dma_map_sg can merge consecutive sglist entries, thus making the original sg count wrong. This is a fix for memory coruption issues observed while testing encryption/decryption of large messages using libkcapi framework. Patch has been tested further by running full suite of tcrypt.ko tests including fuzz tests. Signed-off-by: Thara Gopinath Signed-off-by: Herbert Xu
