Frame Analyzer component

This component processes captured frames and parses them. It provides parsing functionality to other components as well as frame filtering by searching for specific types of frames.

Filtering

Filtering functionality is based on listening to event pool for SNIFFER_EVENTS events. Filtering can be started by calling frame_analyzer_capture_start() and providing it search criteria - currently just search type and BSSID.

It then listens to SNIFFER_EVENTS events, parses captured frames and matches them with search criteria. If some frame matches criteria, it forward this frame (or part of it) to event pool as DATA_FRAME_EVENTS event base.

Parsing

Parsing functionality provides a way for other components to get required data from frame (or its parts). For example parse_eapol_packet will parse EAPOL packet from data frame if available.

Frame structures

This component also provides a header file with structures based on 802.11 standard for parsing purposes.

Usage

If you want to use this package in your project, just pass captures frames from sniffer logic to event loop and start capture by frame_analyzer_capture_start().

Or use just parsing functionality of this component.
