Stores it's partial results in the flow structure.

Victor Julien	6a53ab9c5a	Stream engine memory handling update ... The stream engine memory handling needed updating as it didn't scale. Changes: - pools can now be initialized to size 0, meaning unlimited - stream engine uses a memcap setting. Sessions, segments and aldata is part of this, app layer state isn't. - memory is accounted using a global int that is spinlocked. - a counter for sessions that have not been picked up because of memcap was added. - all reassembly errors are converted to debug msgs.	16 years ago

Steve Grubb	60ad9d29c5	Memory leak cleanup in detectors ... Hello, I ran the code through an analysis program and found several leaks that should be cleaned up. *In src/detect-engine-address-ipv4.c at line 472, the test for ag == NULL will never be true since that is the loop entry test. *In src/detect-engine-port.c at line 1133, the test for p == NULL will never be true since that is the loop entry test. *In src/detect-engine-mpm.c at line 263 is a return without freeing fast_pattern *In src/detect-ack.c at line 80 and 85, data catches the return from malloc. One of them should be deleted. *In src/detect-seq.c at line 81 and 86, data catches the return from malloc. One of them should be deleted. *In src/detect-content.c at line 749, many of the paths that lead to the error exit still has temp pointing to allocated memory. To clean this up, temp should be set to NULL if not immediately assigning and new value. *In src/detect-uricontent.c at line 319, both cd and str needto be freed. At lines 344, str needs to be freed. And at line 347 str and temp need to be freed. *In src/detect-flowbits.c at line 231 and 235, str was not being freed. cd was not being freed at line 235. *In src/detect-flowvar.c at line 127, str was not being freed. At line 194, cd and str were not being freed. *In src/detect-flowint.c at line 277, sfd was not being freed. At line 315, str was not being freed. *In src/detect-pktvar.c at line 121, str was not being freed. At line 188, str and cd was not being freed. *In src/detect-pcre.c at line 389, there is an extra free of "re" that should be deleted. *In src/detect-depth.c at line 42 & 48, str has not been freed. *In src/detect-distance.c at line 49 and 55, str has not been freed *In src/detect-offset.c at line 45, str has not been freed. The patch below fixes these issues. -Steve	16 years ago
