(This should probably be reported to an OpenBSD forum, but I'm not subscribing to any of the lists, so I'm posting this to freebsd-net. I believe pf maintainers watch this list, too...) I've found a minor error in pf_print_host() which is revealed for some time of IPv6 addresses. This routine always (perhaps unintentionally) assumes abbreviate-able consecutive zero's, so, for example, it formats "1:2:3:4:5:6:7:8" as ":2:3:4:5:6:7:8". This can be confirmed by the sample code attached to this message by - saving the file as e.g. "foo.c" - cc -o foo foo.c - ./foo 1:2:3:4:5:6:7:8 I've also attached a proposed patch to this problem. The diff was made against 6-STABLE, but it's probably applicable to other versions. JINMEI, Tatuya Communication Platform Lab.
