Victor Julien 3c72d67635 detect/analyzer: log mask flags and more engine details 7 years ago
Victor Julien 709b3bc1e4 rule analyzer: simple rules to json dumper 8 years ago
Victor Julien 0de86211c6 detect: register dynamic buffers into de_ctx 
Register buffers that are created during rule parsing. Currently
this means an existing buffer with one or more transformations.
 8 years ago
Victor Julien a499a44f7a detect: move buffer type map into detect ctx 
Move previously global table into detect engine ctx. Now that we
can register buffers at rule loading time we need to take concurrency
into account.

Move DetectBufferType to detect.h and update DetectBufferCtx API calls
to include a detect engine ctx reference.

Victor Julien ab1200fbd7 compiler: more strict compiler warnings 
Set flags by default:

    -Wmissing-prototypes
    -Wmissing-declarations
    -Wstrict-prototypes
    -Wwrite-strings
    -Wcast-align
    -Wbad-function-cast
    -Wformat-security
    -Wno-format-nonliteral
    -Wmissing-format-attribute
    -funsigned-char

Fix minor compiler warnings for these new flags on gcc and clang.

Victor Julien 04592efb76 detect: buffer type API 
To replace the hardcoded SigMatch list id's, use this API to register
and query lists by name.

Also allow for registering descriptions and whether mpm is supported.

Registration is only allowed at startup.

Instead use the lists in init_data during setup and the SigMatchData
arrays during runtime.

Jason Ish 1a31bded4a DNP3: dnp3_data, dnp3_func, dnp3_ind, dnp3_obj rule keywords 9 years ago
Victor Julien 0ed119068d detect-app-layer-protocol: implement prefilter 
Introduce 'Protocol detection'-only rules. These rules will only be
fully evaluated when the protocol detection completed. To allow
mixing of the app-layer-protocol keyword with other types of matches
the keyword can also inspect the flow's app-protos per packet.

Implement prefilter for the 'PD-only' rules.

Victor Julien d834173bb8 detect-flow: use dedicated flags 
The flow keyword used flag names that were shared with the
Packet::flowflags field. Some of the flags were'nt used by the packet
though. This lead to waste of some 'flag space'.

This patch defines dedicated flags for the flow keyword and removes
the otherwise unused flags from the FLOW_PKT_* space.

All functions where changed by a script to match this standard.
