IP Filter zeros out the pointer to rcvif when IPSEC is compiled in. Looking at the upstream code, Darren checks for IPSEC only for BSD based kernels. Zeroing out the pointer only when IPSEC is compiled in, regardless whether the mbuf in question was touched by IPSEC or not seems a little sketchy to me. However I'm inclined to use IPSEC_SUPPORT for now until it can be established whether to keep or remove it. -- Cheers, Cy Schubert <cy.schub...@cschubert.com> FreeBSD UNIX: <c...@freebsd.org> Web: http://www.FreeBSD.org The need of the many outweighs the greed of the few. _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
