-If you're using this software and have a rule which ends like this:
-
-flags S
-
-(for TCP), then to make it totally effective, you need to change it to appear
-as follows:
-
-flags S/SA
-
-The problem is that the old code would compare all the TCP flags against the
-rule (which just has "S") to see if that matched exactly. It is very possible
-for this to not be the case and in these cases, the rule would fail to match
-a 'valid' TCP SYN packet.
-
-Why does it need to be "S/SA" and not "S/S" ?
-
-"S/S" will match the SYN-ACK as well the SYN.
-
-By defalt, "flags S" will now be converted to "flags S/AUPRFS".
-
-If you have any queries regarding this, see the examples and ipf(4).
-If you still have a query or suggestion, please email me.

-
-If a filter rule used, in combination port comparisons and the flags
-keywords, a "short" TCP packet, if not explicitly blocked high up in
-the list of packets, would actually get matched even though it would
-otherwise not have been (due to the ports not). This behaviour has
-subsequently been fixed.
