I expect this points at bugzilla 272966 not being a duplicate of this one. Effectively it looks like my builds do not test this "during udp_input" bugzilla. Most of the tests that got panics during udp_input for the snapshot get no panic at all with my build. The ones where "v6" or "netinet6" was involved generally instead get the kind of panic backtrace that bugzilla 272966 reported, including it being during in6ifa_ifwithaddr instead of during udp_input. /usr/bin/kyua test -k /usr/tests/Kyuafile sys/netpfil/pf/get_state:many produced a new backtrace showing a panic during tcp_input_with_port(). (I may end up with a new bugzilla for this.) I plan on submitting my notes in the bugzilla that was reporting the same type of backtrace that I see in my testing. Anything else would just be too confusing about what the evidence was like. Unless panics reappear during udp_input, I consider this bugzilla as basically untested in my future testing of your patches. I still have exploring to do with my build for what, in the snapshot testing, had panics during in6ifa_ifwithaddr. --=20 You are receiving this mail because: You are the assignee for the bug.=
