Bug #2627
closed
IPv6 source address selection broken
0%
Description
Recent DragonFly 3.7 kernels use link-local addresses to talk to hosts on regular unicast prefixes.
This results in traffic beeing rejected by the remote host.
Example of bad behavior:
$ ping6 gw
PING6 fe80::be5f:f4ff:fe38:1bef --> 2001:7a8:3c67:2::254
Same example with a working kernel:
$ ping6 gw
PING6 2001:7a8:3c67:2::12 --> 2001:7a8:3c67:2::254
Reverting commit cfd79120debdd52626136c5985f3a9e3d4fe42bf "jails/netinet6: Only select jailed ips for outgoing"
from January 25 is enough to fix the issue.

Just that it will break jail ipv6 again. I will have a look at it later this week.

this violates rfc6724. I am not sure why this happens because the patch should only have an impact when there's a jail involved.
