Subject: Netfilter callbacks and UDP fragmenting
Date: Mon, 1 Oct 2007 13:23:40 +0200 [thread overview]
Message-ID: <004901c8041d$851a86d0$620aa8c0@nyala> (raw)
Hi,
are UDP packets defragmented before are passed to netfilter callback
functions (e.g. PREROUTING) or developer has to create buffer and
defragment by himself, to release memory when a fragment is missing,
etc. - is there a working implementation/example? How about locally
generated packets in OUTPUT callback?
I've looked e.g. in nf_conntrack_sip.c and I can't see any extra
defragmentation code even SIP message can be fragmented, especially SDP
content.
Thanks
Tomas
