Description (partial)


When a HTTP stream, containing a mix of ip fragments and 
non fragmented packet, matches a content and policy with 
'accounting type http' CSG may leak buffer, causing
all traffic to get dropped by CSG.

The issue occurs only if all of the following conditions are met:
1. The data flow must match a CSG Content-Policy
   pair that is configured for 'accounting type http'
2. CSG sees HTTP packet which is the first packet of a transaction.
3. HTTP packet should be followed by another HTTP packet which gets
   ip fragment before reaching CSG.
4. Under certain timing condition CSG may leak buffer corresponding 
   to first fragment.
