There are two possible ways this can happen: The function m_copym was called with off == 0, or off == m->m_len. Neither is supposed to happen (obviously) so the bug must be in ip_fragment. Lets have a look at that next... > panic() > m_copym() > ip_fragment() > ip_output() > gre_output() > ip_output() > udp_output() > upd_send() > sosend() > kern_sendit() > sendit() > sendto() > syscall() > xint0x80_syscall() > > ... now I'm not sure that the error is perfectly technically > off-by-one, but its something similar. Is this panic reproduceable? What kind of traffic was going on at that time? Or was it right away when you started using the GRE tunnel? Could you please open a PR with this information too? It helps keeping track of the progress. -- Andre _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
