This fixes recvmsg() to be able to peek across multiple tls records. Without this patch, the tls's selftests test case 'recv_peek_large_buf_mult_recs' fails. Each tls receive context now maintains a 'rx_list' to retain incoming skb carrying tls records. If a tls record needs to be retained e.g. for peek case or for the case when the buffer passed to recvmsg() has a length smaller than decrypted record length, then it is added to 'rx_list'. Additionally, records are added in 'rx_list' if the crypto operation runs in async mode. The records are dequeued from 'rx_list' after the decrypted data is consumed by copying into the buffer passed to recvmsg(). In case, the MSG_PEEK flag is used in recvmsg(), then records are not consumed or removed from the 'rx_list'. Signed-off-by: Vakul Garg <vakul.garg@nxp.com> Signed-off-by: David S.
