Anoop Saldanha 420befb180 Changed my email address to anoopsaldanha at gmail dot com from my current one 14 years ago
Victor Julien 89f83e714c Introduce http_server_body keyword.
The http_server_body content modifier modifies the previous content to inspect
the normalized (dechunked, unzipped) http_server_body. The workings are similar
to http_client_body. Additionally, a new pcre flag was introduced "/S".

To facilitate this change the signature flags field was changed to be 64 bit.

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.
