Jakub Kicinski cd1bbca03f net: tls: handle backlogging of crypto requests ... commit 8590541473 upstream. Since we're setting the CRYPTO_TFM_REQ_MAY_BACKLOG flag on our requests to the crypto API, crypto_aead_{encrypt,decrypt} can return -EBUSY instead of -EINPROGRESS in valid situations. For example, when the cryptd queue for AESNI is full (easy to trigger with an artificially low cryptd.cryptd_max_cpu_qlen), requests will be enqueued to the backlog but still processed. In that case, the async callback will also be called twice: first with err == -EINPROGRESS, which it seems we can just ignore, then with err == 0. Compared to Sabrina's original patch this version uses the new tls_*crypt_async_wait() helpers and converts the EBUSY to EINPROGRESS to avoid having to modify all the error handling paths. The handling is identical. Fixes: a54667f672 ("tls: Add support for encryption using async offload accelerator") Fixes: 94524d8fc9 ("net/tls: Add support for async decryption of tls records") Co-developed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Link: https://lore.kernel.org/netdev/9681d1febfec295449a62300938ed2ae66983f28.1694018970.git.sd@queasysnail.net/ Signed-off-by: Jakub Kicinski <kuba@kernel.org> Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: David S.
