Hi, I encountered a problem with IPv6 connectivity after upgrade to snapshot Mar 23 on my amd64 router.
The router use a pppoe session to get IPv4 and IPv6. I had to made a DHCP-ND request to get routable IPv6, and I use dhcpcd from ports for that. The IPv4 is ok, but for IPv6, dhcpcd has the following error: Mar 24 20:16:33 alf dhcpcd[43667]: DUID 00:01:00:01:1e:40:7c:6c Mar 24 20:16:33 alf dhcpcd[43667]: pppoe0: IAID 00:00:00:01 Mar 24 20:16:33 alf dhcpcd[43667]: pppoe0: IAID 00:00:00:02 Mar 24 20:16:33 alf dhcpcd[43667]: pppoe0: rebinding prior DHCPv6 lease Mar 24 20:16:35 alf dhcpcd[43667]: pppoe0: dhcp6_sendmessage: sendmsg: Invalid argument Mar 24 20:17:03 alf dhcpcd[43667]: timed out Mar 24 20:17:03 alf dhcpcd[43667]: forked to background, child pid 10317 I had ktraced it for grabing the sendmsg syscall arguments used: 43667 dhcpcd CALL sendmsg(10,0x1abbb5052020,0) 43667 dhcpcd STRU struct msghdr { name=0x7f7ffffc5260, namelen=28, iov=0x1abbb5052050, iovlen=1, control=0x1abbb5052070, controllen=40, flags=0 } 43667 dhcpcd STRU struct iovec { base=0x1abb901b5000, len=167 } 43667 dhcpcd STRU struct sockaddr { AF_INET6, [ff02::1:2]:547 } 43667 dhcpcd STRU struct cmsghdr { len=36, level=41<ipv6>, type=46 } 43667 dhcpcd RET sendmsg -1 errno 22 Invalid argument Below a full dmesg.
