I have scanned through mailinglists looking for which "false alerts" these TCP
checks will stop.   I get the following messages in my alert file

(snort_decoder): Short UDP packet, length field > payload length
(snort_decoder) WARNING: TCP Header length exceeds packet length!
(snort_decoder): Truncated Tcp Options

where can i find an explanation of what these means "Stop generic decode event",
"Stop alerts on experimental TCP options", etc.

Have a look in snort.conf.  There's a whole section that deals with those
types of alerts!  :)
