Hi,
according to the comment in usr.sbin/ripd/packet.c, ripd(8) fails to
find the interface on which a packet was received when the source
and destination addresses of the interface do not share the same
subnet.
Here is a patch: http://www.durlej.net/tmp/ripd-p2p.diff
It's not clear to me if you tested your diff or not. Anyway, you
should better send it *inline* to tech@ with an explanation of which
problem it solves. Test for regressions are also much appreciated.
Of course, the patch has been tested before being posted.
As for sending the patch inline, because of some git diff decorations,
the patch contains a line over 72 characters long. AFAIK, messages
with such a long lines are frowned upon on OpenBSD mailing lists.
Finally, the problem solved by this patch:
