Typedef Documentation

◆ AppLayerParserState

typedef struct AppLayerParserState_ AppLayerParserState

Definition at line 1 of file flow.h.

◆ Flow

typedef struct Flow_ Flow

Flow data structure.

The flow is a global data structure that is created for new packets of a flow and then looked up for the following packets of a flow.

Locking

The flow is updated/used by multiple packets at the same time. This is why there is a flow-mutex. It's a mutex and not a spinlock because some operations on the flow can be quite expensive, thus spinning would be too expensive.

The flow "header" (addresses, ports, proto, recursion level) are static after the initialization and remain read-only throughout the entire live of a flow. This is why we can access those without protection of the lock.
