Subject: libnetfilter_queue question
Date: Wed, 19 May 2010 12:15:35 +0200	[thread overview]
Message-ID: <4BF3BA47.7040109@inliniac.net> (raw)

Hi all,

I'm using libnetfilter_queue for inline mode in the Suricata IDS/IPS
(www.openinfosecfoundation.org). I'm using a callback that makes the
packet(s) available to the detection engine. In some special cases the
call back could fail (only malloc failure atm).

I was wondering what the proper response would be to such an event. I'm
assuming nfq_handle_packet() would return an (non zero) error code in
that case.

Should I verdict the packet? (drop to be safe)

Cheers,
Victor
