Benjamin Coddington ecb1356a97 tls: Fix tls_sw_sendmsg error handling ... [ Upstream commit b341ca51d2679829d26a3f6a4aa9aee9abd94f92 ] We've noticed that NFS can hang when using RPC over TLS on an unstable connection, and investigation shows that the RPC layer is stuck in a tight loop attempting to transmit, but forever getting -EBADMSG back from the underlying network. The loop begins when tcp_sendmsg_locked() returns -EPIPE to tls_tx_records(), but that error is converted to -EBADMSG when calling the socket's error reporting handler. Instead of converting errors from tcp_sendmsg_locked(), let's pass them along in this path. The RPC layer handles -EPIPE by reconnecting the transport, which prevents the endless attempts to transmit on a broken connection.
