Macro Definition Documentation

◆ EXP_PDU_3GPP_ID_CGI

#define EXP_PDU_3GPP_ID_CGI 0

56-bit 2G/3G Cell Global Identifier (MNC big-endian encoding)

◆ EXP_PDU_3GPP_ID_ECGI

#define EXP_PDU_3GPP_ID_ECGI 1

52-bit 4G E-UTRAN Cell Global Identifier (MNC big-endian encoding)

◆ EXP_PDU_3GPP_ID_NCGI

#define EXP_PDU_3GPP_ID_NCGI 2

60-bit NR Cell Global Identifier (MNC big-endian encoding) Stores a 3GPP identifier. The value begins with a 1-byte identity type (EXP_PDU_3GPP_ID_*), followed by the identity itself.

◆ EXP_PDU_TAG_COL_INFO_TEXT

#define EXP_PDU_TAG_COL_INFO_TEXT 36

UTF-8 text string to put in COL_INFO, useful when putting meta data into the packet list.

◆ EXP_PDU_TAG_COL_PROT_TEXT

#define EXP_PDU_TAG_COL_PROT_TEXT 33

UTF-8 text string to put in COL_PROTOCOL, one use case is in conjunction with dissector tables where COL_PROTOCOL might not be filled in. value part is structure passed into TCP subdissectors. The field begins with a 2-byte version number; if the version number value is 1, the value part is in the form:

version 2 bytes - xport PDU version of structure (for backwards/forwards compatibility) seq 4 bytes - Sequence number of first byte in the data nxtseq 4 bytes - Sequence number of first byte after data lastackseq 4 bytes - Sequence number of last ack is_reassembled 1 byte - Non-zero if this is reassembled data flags 2 bytes - TCP flags urgent_pointer 2 bytes - Urgent pointer value for the current packet

All multi-byte values are in big-endian format. There is no alignment padding between values, so seq. nxtseq, and lastackseq are not aligned on 4-byte boundaries, andflags and urgent_pointer are not aligned on 2-byte boundaries.

◆ EXP_PDU_TAG_DISSECTOR_NAME

#define EXP_PDU_TAG_DISSECTOR_NAME 12

The value part should be an ASCII non NULL terminated string of the registered dissector used by Wireshark e.g "sip" Will be used to call the next dissector. NOTE: this is NOT a protocol name; a given protocol may have multiple dissectors, if, for example, the protocol headers depend on the protocol being used to transport the protocol in question.

◆ EXP_PDU_TAG_DISSECTOR_TABLE_NAME

#define EXP_PDU_TAG_DISSECTOR_TABLE_NAME 14

The value part should be an ASCII non NULL terminated string containing the dissector table name given during registration, e.g "gsm_map.v3.arg.opcode" Will be used to call the next dissector.

◆ EXP_PDU_TAG_DISSECTOR_TABLE_NAME_NUM_VAL

#define EXP_PDU_TAG_DISSECTOR_TABLE_NAME_NUM_VAL 32

value part is the numeric value to be used calling the dissector table given with tag EXP_PDU_TAG_DISSECTOR_TABLE_NAME, must follow immediately after the table tag.

◆ EXP_PDU_TAG_DST_PORT

#define EXP_PDU_TAG_DST_PORT 26

destination port - 4 bytes (even for protocols with 2-byte ports)

◆ EXP_PDU_TAG_END_OF_OPT

#define EXP_PDU_TAG_END_OF_OPT 0

This is the format of the link-layer header of packets of type LINKTYPE_WIRESHARK_UPPER_PDU in pcap and pcapng files.

It is a sequence of TLVs; at least one TLV MUST indicate what protocol is in the PDU following the TLVs.

Each TLV contains, in order:

a 2-byte big-endian type field; a 2-byte big-endian length field; a value, the length of which is indicated by the value of the length field (that value does not include the length of the type or length fields themselves).

Buffer layout: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Option Code | Option Length | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ / Option Value / / variable length, aligned to 32 bits / +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ / / / . . . other options . . . / / / +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Option Code == opt_endofopt | Option Length == 0 | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

The list of TLVs may begin with a TLV of type EXP_PDU_TAG_OPTIONS_LENGTH; its value is a 4-byte integer value, giving the length of all TLVs following that TLV (i.e., the length does not include the length of the EXP_PDU_TAG_OPTIONS_LENGTH TLV). This tag is deprecated; it is not guaranteed to be present, and code reading packets should not require it to be present.

The last TLV is of type EXP_PDU_TAG_END_OF_OPT; it has a length of 0, and the value is zero-length.

For string values, a string may have zero, one, or more null bytes at the end; code that reads the string value must not assume that there are, or are not, null bytes at the end. Null bytes are included in the length field, but are not part of the string value.

For integral values, the values are in big-endian format. End-of-options Tag.

◆ EXP_PDU_TAG_HEUR_DISSECTOR_NAME

#define EXP_PDU_TAG_HEUR_DISSECTOR_NAME 13

The value part should be an ASCII non NULL terminated string containing the heuristic dissector unique short name given during registration, e.g "sip_udp" Will be used to call the next dissector.

◆ EXP_PDU_TAG_IPV4_DST

#define EXP_PDU_TAG_IPV4_DST 21

IPv4 destination address - 4 bytes

◆ EXP_PDU_TAG_IPV4_SRC

#define EXP_PDU_TAG_IPV4_SRC 20

IPv4 source address - 4 bytes

◆ EXP_PDU_TAG_IPV6_DST

#define EXP_PDU_TAG_IPV6_DST 23

IPv6 destination address - 16 bytes

◆ EXP_PDU_TAG_IPV6_SRC

#define EXP_PDU_TAG_IPV6_SRC 22

IPv6 source address - 16 bytes

◆ EXP_PDU_TAG_LINKTYPE

#define EXP_PDU_TAG_LINKTYPE 11

Deprecated - do not use

◆ EXP_PDU_TAG_OPTIONS_LENGTH

#define EXP_PDU_TAG_OPTIONS_LENGTH 10

Total length of the options excluding this TLV Deprecated - do not use

◆ EXP_PDU_TAG_P2P_DIRECTION

#define EXP_PDU_TAG_P2P_DIRECTION 35

The packet direction (P2P_DIR_SENT, P2P_DIR_RECV).

◆ EXP_PDU_TAG_PORT_TYPE

#define EXP_PDU_TAG_PORT_TYPE 24

part type - 4 bytes, EXP_PDU_PT value

◆ EXP_PDU_TAG_SRC_PORT

#define EXP_PDU_TAG_SRC_PORT 25

source port - 4 bytes (even for protocols with 2-byte ports)

◆ EXP_PDU_TAG_USER_DATA_PDU

#define EXP_PDU_TAG_USER_DATA_PDU 37

Raw user data PDU which can be dissected as any protocol.
