Author: ae Date: Mon Feb 5 09:25:02 2018 New Revision: 328877 URL: https://svnweb.freebsd.org/changeset/base/328877 Log: MFC r328770: Merge r1.120 from NetBSD: Fix a pretty simple, yet pretty tragic typo: we should return IPPROTO_DONE, not IPPROTO_NONE. With IPPROTO_NONE we will keep parsing the header chain on an mbuf that was already freed.
