https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=294114 Bug ID: 294114 Summary: ipfw: nptv6 (with ext_if) fails to react on address removal Product: Base System Version: 14.4-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: pmc@citylink.dinoex.sub.org To reproduce: 1. sentinel-interface has the current address/prefix, and nptv6 is correctly translating. 2. now the prefix gets changed, and we configure the interface in two steps: # ifconfig vtnet0 inet6 <new-address> # ifconfig vtnet0 inet6 <old-address> -alias Result: nptv6 does still translate to the old address, and dtrace did not show an invocation of nptv6_find_prefix(). Analysis/Fix: a comparison in ifaddr_cb() is strictly wrong.
