https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233955 --- Comment #29 from commit-hook@freebsd.org --- A commit references this bug: Author: kevans Date: Tue Apr 23 17:28:28 UTC 2019 New revision: 346602 URL: https://svnweb.freebsd.org/changeset/base/346602 Log: tun(4): Defer clearing TUN_OPEN until much later tun destruction will not continue until TUN_OPEN is cleared. There are br= ief moments in tunclose where the mutex is dropped and we've already cleared TUN_OPEN, so tun_destroy would be able to proceed while we're in the midd= le of cleaning up the tun still. tun_destroy should be blocked until these parts (address/route purges, mostly) are complete.
