Subject: UDP packet and INVALID state
Date: Sun, 15 May 2011 17:15:38 +0200 [thread overview]
Message-ID: <4DCFEE1A.2080504@plouf.fr.eu.org> (raw)
Hello all,
What are the possible conditions for a UDP packet to have the INVALID
state but still be accepted by the destination ?
I already found a previous reply from Jozsef Kadlecsik mentionning the
following conditions :
- the header is too small, truncated or malformed, etc.) ;
- the IP addresses or the protocol parameters (ports) for a unique
tuple (src ip, dst ip, proto, src "port", dst "port") cannot be
extracted from the packet.
But wouldn't that also make the destination discard the packet ?
Are there other conditions ?
Maybe if the conntrack table is full ?
Thanks for all insights.
