Victor Julien 679b8ec1ba Fix filestore match code not expecting NULL file ptr. 14 years ago
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.

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.

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 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.

Victor Julien a138b32533 flow manager: timing change 
Set default timeout for the flow manager to wake up to 1 second. The 0.4 sec
performed best on a Xeon, but in kvm vm's it was horrible:

32 bit vm: 60% cpu for flowmgr when idle.
64 bit vm: 30% cpu for flowmgr when idle.

With the 1 second timeout both are at 0.3% cpu.

Eric Leblond 5a63662766 Flow: use condition system instead of short sleep 
Short sleep can lead to some really annoying performance issue in
some environnement like virtual systems. This technic was used in
the flow manager. This patch uses an alternate approach based on
a timed condition which is triggered each time a new flow has to
be created. This avoid to run out of flow. A counter is also done
to be able not to run the cleaning code at each new flow.

Victor Julien 9878eca086 file handling: expand filestore keyword 
Filestore keyword by default (... filestore; ... ) marks only the file in the
same direction as the rule match for storing. This makes sense when inspecting
individual files (filemagic, filename, etc) but not so much when looking at
suspicious file requests, where the actual file is in the response.

The filestore keyword now takes 2 optional options:

filestore:<direction>,<scope>;

By default the direction is "same as rule match", and scope is "currently
inspected file".

For direction the following values are possible: "request" and "to_server",
"response" and "to_client", "both".

For scope the following values are possible: "tx" for all files in the current
HTTP/1.1 transation, "ssn" and "flow" for all files in the session/flow.

For the above case, where a suspious request should lead to a response file
download, this would work:

alert http ... content:"/suspicious/"; http_uri; filestore:response; ...

Victor Julien 425294f912 stream reassembly: account stream gaps

Victor Julien b74c73309b file handling: improve filestore keyword handling

Victor Julien 262a7300d7 flow: shrink Flow datatype 
Introduce a separate FlowAddress structure for holding the ipv4 or ipv6 address
that doesn't have the family in it like the Address structure. Instead, the
family is stored in the flow as a flag: FLOW_IPV4 and FLOW_IPV6.

Add macro's to check the family, copy the address, etc.

Update many unittests to reflect these changes. Introduce unittest helper
functions for creating and initializing a flow and freeing it again.

On 64 bit this shrinks the flow with 8 bytes.

Updated lots of unittests to reflect these changes.
