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.

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.
