Hi, during network driver testing I sometimes do a stress test with
while true; do ifconfig vio0 -inet; done & while true; do ifconfig vio0 inet autoconf; done & while true; do ifconfig vio0 -inet6; done & while true; do ifconfig vio0 inet6 autoconf; done & while true; do ifconfig vio0 down; done & while true; do ifconfig vio0 up; done & After I stop these jobs, "ifconfig vio0 autoconf" does not work any more because dhcpleased has died: Sep 4 14:20:39 oatest dhcpleased[19462]: bpf_send_packet: writev: Network is down Sep 4 14:20:39 oatest dhcpleased[19462]: bpf_send_packet: writev: Network is down Sep 4 14:20:39 oatest dhcpleased[19462]: bpf_send_packet: writev: Network is down Sep 4 14:20:39 oatest dhcpleased[19462]: bpf_send_packet: writev: Network is down Sep 4 14:20:40 oatest dhcpleased[19462]: bpf_send_packet: writev: Network is down Sep 4 14:20:40 oatest dhcpleased[80648]: fatal in main: msgbuf_write: Broken pipe This is obviously not a severe bug, but slaacd survives the stress test. Maybe dhcpleased could improve its error handling, too? Cheers, Stefan
