6.5-stable review patch. If anyone has any objections, please let me know.
------------------ From: Eric Dumazet <eduma...@google.com> [ Upstream commit f4f82c52a0ead5ab363d207d06f81b967d09ffb8 ] Nothing prevents iscsi_sw_tcp_conn_bind() to receive file descriptor pointing to non TCP socket (af_unix for example). Return -EINVAL if this is attempted, instead of crashing the kernel.
