Hannes Frederic Sowa 08c62a109e inet: fix addr_len/msg->msg_namelen assignment in recv_error and rxpmtu functions ... [ Upstream commit 85fbaa7503 ] Commit bceaa90240 ("inet: prevent leakage of uninitialized memory to user in recv syscalls") conditionally updated addr_len if the msg_name is written to. The recv_error and rxpmtu functions relied on the recvmsg functions to set up addr_len before. As this does not happen any more we have to pass addr_len to those functions as well and set it to the size of the corresponding sockaddr length. This broke traceroute and such.
