Detailed Description

Author

Victor Julien victo.nosp@m.r@in.nosp@m.linia.nosp@m.c.ne.nosp@m.t

Proto part of the detection engine.

Todo:

move this out of the detection plugin structure

Definition in file detect-engine-proto.c.

Function Documentation

int DetectProtoContainsProto	(	const DetectProto *	dp,
		int	proto
	)

see if a DetectProto contains a certain proto

Parameters

dp	detect proto to inspect
proto	protocol (such as IPPROTO_TCP) to look for

Return values

0	protocol not in the set
1	protocol is in the set

int DetectProtoParse	(	DetectProto *	dp,
		const char *	str
	)

Parses a protocol sent as a string.

Parameters

dp	Pointer to the DetectProto instance which will be updated with the incoming protocol information.
str	Pointer to the string containing the protocol name.

Return values

>=0	If proto is detected, -1 otherwise.

Todo:

are numeric protocols even valid?
