The version of gen-msg.map in the source tarballs is the same in 2.9.6.0, 2.9.6.1, and 2.9.6.2.  The version of 
gen-msg.map on labs is the same in 2.9.6.0 (http://labs.snort.org/snort/2960/gen-msg.map) and 2.9.6.1 
(http://labs.snort.org/snort/2961/gen-msg.map); there is no 2.9.6.2 (http://labs.snort.org/snort/2962/) on labs yet.

This has been corrected.  The correct 2.9.6.2 files have been uploaded.


The differences between the source and labs versions are as follows:

shell> diff snort-2.9.6.1/etc/gen-msg.map labs2961/gen-msg.map

However, the source code does not appear to support any of the 6 alerts added in the gen-msg.map on labs; definitions 
for other alerts from generator ID 120 reside in src/preprocessors/HttpInspect/include/hi_eo_events.h. Does gen-msg.map 
on labs need to be replaced with a correct version?

This is a 2.9.7.0 feature.  (SWF and PDF decompression).  Sorry about that.
