Hi all. What I look for is reimplementing a part of NFQUEUE functionality at the stage where TCP packet is formed before sending to network. It seems that NFQUEUE can't just handle expanded (> MTU) packet, and also want to have control over SEQ/ACK numbers assigned to both packets and connection structures. But errr.. where to look for? The sources are too complex and there's not enough guides. Actually I have this doc only: http://www.nsnam.org/wiki/index.php/GSOC2009Netfilter#Callback_Priority Can anyone point me to correct place in kernel sources to see/attach with SystemTap and track how SEQs are generated and how outgoing packets are planned to be fragmented or even dropped? Deliberately want a good tour. P.S. There's at least 2 projects that can benefit from such transparent packet size growing, one is mine and second is StegBox (steganography based covert channels in traffic) -- cheers, Igor -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
