Victor Julien 679b8ec1ba Fix filestore match code not expecting NULL file ptr. 13 years ago
Steve Grubb a65eb59c41 Add relro flags to libhtp 
Hello,

The main suricata program can detect and use relro/bind now linker flags. But
the directive is per linked object. This means that while the app has
protection, its code segment containing libhtp does not. The patch below passes
the configure option to libhtp and let's it make use of the compiler's
security protection.

Victor Julien 18d79c4215 file store: respect flowbits and other keywords 
The filestore keyword until now flagged a file, tx or ssn for storage as soon
as the keyword was inspected. This happens before flowbits and some other
keywords, so files were stored that weren't supposed to.

This patch makes the filestore keyword fill an array in the detect engine
thread ctx. Then if the full signature matches, a post-match filestore
function makes the store final.

Victor Julien 077970051e file-data: implement relative pcre support. 13 years ago
Victor Julien 07e560b137 file-data: initial file_data support 
Support file_data for: content, pcre (relative), byte_test, byte_jump,
byte_extract, isdataat.

File_data support is handled at signature parsing time, all matches
occurring after the file_data in the rule are converted to http_server_body
matches.

Content matches relative to the file_data are converted. Within to depth,
distance to offset. Relative to the start of the body buffer.

Victor Julien 6ebd71545b Fix signature flag definitions on 32 bit. 13 years ago
Victor Julien 291ddd95f2 Detection engine -- mpm 
Each signature is in one mpm ctx at max, but there were 3 separate
id's in use: packet, stream, http. Merged them all into one.

Could shrink the SignatureHeader structure with 8 bytes because of this,
should lead to better caching performance.

Victor Julien 7db72bce75 Optimize detection engine prefiltering logic. 13 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.

Eileen Donlon 327fd048a0 Fixed coredump windows compile issue 13 years ago
Eric Leblond 6c55af847b 'auto' running mode does not support 'threads' var. 
This patch modifies the RunModeSetLiveCaptureAuto() prototype to
be able to detect that a 'threads' variable (telling how much
threads must listen to one socket in IDS mode) has been used
in the configuration file. It then print a warning message
if this is the case.
