Hi snort-devel, The attached patch adds support for reading the 'Nonce Sum' bit of the TCP Flags byte, as defined in RFC 3540. The order of the 'C' and 'E' bit case statements are moved around to put them into logical (LSB) order (FSRPAUECN). It also fixes the TCPHEADER_NORESERVED macro in src/dynamic-plugins/sf_engine/sf_snort_packet.h, which was missing the ECE/CWR bits, and adds TCPHEADER_NS to it as well. The TeX for the manual is also updated. doc/snort_manual.tex | 7 ++-- src/detection-plugins/sp_tcp_flag_check.c | 35 +++++++++++++++--------- src/dynamic-plugins/sf_engine/sf_snort_packet.h | 4 ++ src/rules.h | 1 4 files changed, 31 insertions(+), 16 deletions(-) Cheers!, -- Joshua Kinard Gentoo/MIPS kumba () gentoo org 4096R/D25D95E3 2011-03-28 "The past tempts us, the present confuses us, the future frightens us.

Thanks for the patch Joshua. We've created a feature bug to get this into Snort. Todd
