https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219250 --- Comment #5 from commit-hook@freebsd.org --- A commit references this bug: Author: vangyzen Date: Tue Nov 27 19:40:07 UTC 2018 New revision: 341086 URL: https://svnweb.freebsd.org/changeset/base/341086 Log: MFC r340257 in6_ifattach_linklocal: handle immediate removal of the new LLA If another thread immediately removes the link-local address added by in6_update_ifa(), in6ifa_ifpforlinklocal() can return NULL, so the following assertion (or dereference) is wrong. Remove the assertion, and handle NULL somewhat better than panicking. This matches all of the other callers of in6_update_ifa().
