Vakul Garg 65a10e28ae tls: Do not call sk_memcopy_from_iter with zero length ... In some conditions e.g. when tls_clone_plaintext_msg() returns -ENOSPC, the number of bytes to be copied using subsequent function sk_msg_memcopy_from_iter() becomes zero. This causes function sk_msg_memcopy_from_iter() to fail which in turn causes tls_sw_sendmsg() to return failure. To prevent it, do not call sk_msg_memcopy_from_iter() when number of bytes to copy (indicated by 'try_to_copy') is zero.
