It seems that the update forgot to fill sa_len in the struct sockaddr. The result is solo% mtr freefall.freebsd.org ~ Error decoding localhost address mtr: Failure to start mtr-packet: Invalid argument The 'error' part comes from mtr-packet, which does the following 62130 mtr-packet CALL socket(PF_INET,0x2<SOCK_DGRAM>,IPPROTO_UDP) 62130 mtr-packet RET socket 8 62130 mtr-packet CALL connect(0x8,0x7fffffffb550,0x4) 62130 mtr-packet STRU struct sockaddr { AF_INET, invalid } 62130 mtr-packet RET connect -1 errno 22 Invalid argument 62130 mtr-packet CALL close(0x8)
