Shivani Bhardwaj bb7009f2f4 websocket: trigger raw stream inspection ... Internals --------- Suricata's stream engine returns data for inspection to the detection engine from the stream when the chunk size is reached. Bug --- Inspection triggered only in the specified chunk sizes may be too late when it comes to inspection of smaller protocol specific data which could result in delayed inspection, incorrect data logged with a transaction and logs misindicating the pkt that triggered an alert. Fix --- Fix this by making an explicit call from all respective applayer parsers to trigger raw stream inspection which shall make the data available for inspection in the following call of the stream engine. This needs to happen per direction on the completion of an entity like a request or a response. Important notes --------------- 1. The above mentioned behavior with and without this patch is affected internally by the following conditions. - inspection depth - stream depth In these special cases, the inspection window will be affected and Suricata may not consider all the data that could be expected to be inspected. 2. This only applies to applayer protocols running over TCP. 3. The inspection window is only considered up to the ACK'd data. 4. This entire issue is about IDS mode only. Websocket parser creates a new PDU per transaction in each direction. Appropriate calls to trigger raw stream inspection have been added on succesful parsing of each PDU.
