Detailed Description

The conversation API lets you correlate packets based on values in a packet, typically address+port tuples. You can search for conversations based on their value tuples and attach data to them.

Macro Definition Documentation

◆ NO_ADDR2

#define NO_ADDR2 0x01

Flags to pass to "conversation_new()" to indicate that the address 2 and/or port 2 values for the conversation should be wildcards. The CONVERSATION_TEMPLATE option tells that any of the other supplied port and / or address wildcards will be used to match an infinite number of new connections to the conversation(s) that have the CONVERSATION_- TEMPLATE flag set. Any conversation created without the CONVERSATION_- TEMPLATE flag will be altered once the first connections (connection oriented protocols only) to include the newly found information which matched the wildcard options.

◆ NO_MASK_B

#define NO_MASK_B 0xFFFF0000

Flags to pass to "find_conversation()" to indicate that the address B and/or port B search arguments are wildcards.

◆ USE_LAST_ENDPOINT

#define USE_LAST_ENDPOINT 0x08

Flags to handle endpoints Use last endpoint created, regardless of type

Typedef Documentation

◆ conversation_element_t

typedef struct conversation_element conversation_element_t

Elements used to identify conversations for *_full routines and pinfo->conv_elements. Arrays must be terminated with an element .type set to CE_CONVERSATION_TYPE.

This is currently set only by conversation_set_elements_by_id(); it is not set for conversations identified by address/port endpoints.

In find_conversation_pinfo() and find_or_create_conversation(), if any dissector has set this, then, unless some dissector has set the pair of address/port endpoints (see below), the array of elements is used to look up or create the conversation. Otherwise, the current addresses and ports in the packet_info structure are used.

XXX - is there any reason why we shouldn't use an array of conversation elements, with the appropriate addresses and ports, and set it for all protocols that use conversations specified by a pair of address/port endpoints? That might simplify find_conversation_pinfo() by having them always use the array of elements if it's present, and just fail if it's not.

◆ find_conversation()

WS_DLL_PUBLIC conversation_t * find_conversation	(	const uint32_t	frame_num,

		const address *	addr_b,
		const conversation_type	ctype,
		const uint32_t	port_a,
		const uint32_t	port_b,
		const unsigned	options
	)

Given two address/port pairs for a packet, search for a conversation containing packets between those address/port pairs. Returns NULL if not found.

We try to find the most exact match that we can, and then proceed to try wildcard matches on the "addr_b" and/or "port_b" argument if a more exact match failed.

Either or both of the "addr_b" and "port_b" arguments may be specified as a wildcard by setting the NO_ADDR_B or NO_PORT_B flags in the "options" argument. We do only wildcard matches on addresses and ports specified as wildcards.

I.e.:

if neither "addr_b" nor "port_b" were specified as wildcards, we do an exact match (addr_a/port_a and addr_b/port_b) and, if that succeeds, we return a pointer to the matched conversation;

otherwise, if "port_b" wasn't specified as a wildcard, we try to match any address 2 with the specified port 2 (addr_a/port_a and {any}/addr_b) and, if that succeeds, we return a pointer to the matched conversation;

otherwise, if "addr_b" wasn't specified as a wildcard, we try to match any port 2 with the specified address 2 (addr_a/port_a and addr_b/{any}) and, if that succeeds, we return a pointer to the matched conversation;

otherwise, we try to match any address 2 and any port 2 (addr_a/port_a and {any}/{any}) and, if that succeeds, we return a pointer to the matched conversation;

otherwise, we found no matching conversation, and return NULL.

Null address values will be replaced with empty (AT_NONE) addresses.

Parameters

frame_num	Frame number. Must be greater than or equal to the conversation's initial frame number.
addr_a	The first address in the identifying tuple.
addr_b	The second address in the identifying tuple.
ctype	The conversation type.
port_a	The first port in the identifying tuple.
port_b	The second port in the identifying tuple.
options	Wildcard options as described above.

Returns: The matching conversation if found, otherwise NULL.

◆ find_conversation_deinterlacer_pinfo()

WS_DLL_PUBLIC conversation_t * find_conversation_deinterlacer_pinfo ( const packet_info * pinfo )

A wrapper function of find_conversation_deinterlacer() using data from pinfo, which evaluates the execution context first (user preference, VLAN, interface,..), and then calls find_conversation_deinterlacer(). The frame number and addresses are taken from pinfo.

◆ find_conversation_full()

WS_DLL_PUBLIC conversation_t * find_conversation_full	(	const uint32_t	frame_num,
		conversation_element_t *	elements
	)

Search for a conversation based on the structure and values of an element list.

Parameters

frame_num	Frame number. Must be greater than or equal to the conversation's initial frame number.
elements	An array of element types and values. Must not be NULL. Must be terminated with a CE_CONVERSATION_TYPE element.

Returns: The matching conversation if found, otherwise NULL.

◆ find_conversation_pinfo()

WS_DLL_PUBLIC conversation_t * find_conversation_pinfo	(	const packet_info *	pinfo,
		const unsigned	options
	)

A helper function that calls find_conversation() using data from pinfo The frame number and addresses are taken from pinfo.

◆ find_conversation_pinfo_ro()

WS_DLL_PUBLIC conversation_t * find_conversation_pinfo_ro	(	const packet_info *	pinfo,
		const unsigned	options
	)

A helper function that calls find_conversation() using data from pinfo. It's a simplified version of find_conversation_pinfo() to avoid unnecessary checks and be limited to read-only, which is the minimal need for displaying packets in packet_list. The frame number and addresses are taken from pinfo.

A helper function that calls find_conversation() using data from pinfo, as above, but somewhat simplified for being accessed from packet_list. The frame number and addresses are taken from pinfo.

◆ find_conversation_strat()

WS_DLL_PUBLIC conversation_t * find_conversation_strat	(	const packet_info *	pinfo,
		const conversation_type	ctype,
		const unsigned	options
	)

A helper function that calls find_conversation() using data from pinfo, and returns a conversation according to the runtime deinterlacing strategy. The frame number and addresses are taken from pinfo.

◆ find_or_create_conversation()

WS_DLL_PUBLIC WS_RETNONNULL conversation_t * find_or_create_conversation ( packet_info * pinfo )

A helper function that calls find_conversation() and, if a conversation is not found, calls conversation_new(). The frame number and addresses are taken from pinfo. No options are used, though we could extend this API to include an options parameter.

Parameters

pinfo Packet info.

Returns: The existing or new conversation.

◆ find_or_create_conversation_by_id()

WS_DLL_PUBLIC WS_RETNONNULL conversation_t * find_or_create_conversation_by_id	(	packet_info *	pinfo,
		const conversation_type	ctype,
		const uint32_t	id
	)

A helper function that calls find_conversation_by_id() and, if a conversation is not found, calls conversation_new_by_id(). The frame number is taken from pinfo.

◆ get_conversation_hashtables()

WS_DLL_PUBLIC wmem_map_t * get_conversation_hashtables ( void )

Get a hash table of conversation hash table.

Returns: A wmem_map_t * of (const char *: wmem_map_t *). Each value is a wmem_map_t * of (const conversation_element_t *: void *).

◆ try_conversation_dissector()

WS_DLL_PUBLIC bool try_conversation_dissector	(	const address *	addr_a,
		const address *	addr_b,
		const conversation_type	ctype,
		const uint32_t	port_a,
		const uint32_t	port_b,
		tvbuff_t *	tvb,
		packet_info *	pinfo,
		proto_tree *	tree,
		void *	data,
		const unsigned	options
	)

Given two address/port pairs for a packet, search for a matching conversation and, if found and it has a conversation dissector, call that dissector and return true, otherwise return false.

This helper uses call_dissector_only which will NOT call the default "data" dissector if the packet was rejected. Our caller is responsible to call the data dissector explicitly in case this function returns false.
