Macro Definition Documentation

◆ DETECT_PROTO_ANY

#define DETECT_PROTO_ANY BIT_U8(0)

Indicate that given protocol is considered as IP

Definition at line 29 of file detect-engine-proto.h.

◆ DETECT_PROTO_IPV4

#define DETECT_PROTO_IPV4 BIT_U8(3)

IPv4 only

Definition at line 32 of file detect-engine-proto.h.

◆ DETECT_PROTO_IPV6

#define DETECT_PROTO_IPV6 BIT_U8(4)

IPv6 only

Definition at line 33 of file detect-engine-proto.h.

◆ DETECT_PROTO_ONLY_PKT

#define DETECT_PROTO_ONLY_PKT BIT_U8(1)

Indicate that we only care about packet payloads.

Definition at line 30 of file detect-engine-proto.h.

◆ DETECT_PROTO_ONLY_STREAM

#define DETECT_PROTO_ONLY_STREAM BIT_U8(2)

Indicate that we only care about stream payloads.

Typedef Documentation

◆ DetectProto

typedef struct DetectProto_ DetectProto

Function Documentation

◆ DetectProtoContainsProto()

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

Definition at line 135 of file detect-engine-proto.c.

References DETECT_PROTO_ANY, DetectProto_::flags, proto, and DetectProto_::proto.

◆ DetectProtoParse()

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?
