https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264739 Peter Much <pmc@citylink.dinoex.sub.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |pmc@citylink.dinoex.sub.org --- Comment #5 from Peter Much <pmc@citylink.dinoex.sub.org> --- I was just hit by this bug also, as it crashes my IPS: suricata[13989]: [105773] <Warning> -- [ERRCODE: SC_WARN_IPFW_XMIT(84)] - Write to ipfw divert socket failed: Address family not supported by protocol family suricata[13989]: [105588] <Error> -- [ERRCODE: SC_ERR_FATAL(171)] - thread W-8677 failed This happens every time at the moment when an SMTP connection via IPv6 switches to STARTTLS. (I can do it manually in telnet: the connection builds up normally, and after I type in STARTTLS on the client side, the crash happens.) I do not see why the protocol family of an active tcp session on port 25 would change when deciding to do TLS. For now I have changed the IPS to ignore this errorcode, and apparently that helps - a mail went through successfully, with no anomalies visible in tcpdump. I'll attach my patch on security/suricata -- You are receiving this mail because: You are on the CC list for the bug.
