2012-04-19From Cristian Constantin:Anders Broman1-0/+2
while caching the last element from the conversation hash chain lists speeds-up the operation when the hash/chain lists are actually built, it does NOT help a lot when a certain random conversation which is in the hash table is looked-up. I did some profiling and tracing and I saw that a lot of cpu time is spent in the function conversation_lookup_hashtable() when wireshark is asked to show the "Flow Graph", "TCP Conversations", "Voip Calls". I used two types of captures with over 500k packets: - tcp packets having the _same_ src ip addr, src tcp port, dst ip addr, dst tcp port - (mostly) sip packets containing sdp payloads which advertise the _same_ ip addr, udp port for media these types of captures lead to _huge_ chain lists behind the same hash bucket (to which the conversation is actually mapped) the solution would be to cache the last found conversation into the head of the chain list and to use it whenever it is possible; most of the time the look-up will be in O(1) instead of O(n) (n - number of elements in the list). https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7149 svn path=/trunk/; revision=42141

- conversation.[ch] - To support not setting port2 on matching a conversation. This is used by protocols such as iSNS in which the client registers a TCP/UDP port with the server for notifications and the server sends notifications to this port from different source ports. - packet-isns.c - Added support for handling zero-length TLVs and ESI & SCN frames (when registering an SCN/ESI port, a conversation dissector is setup). svn path=/trunk/; revision=11320

2001-11-27Change "conversation_set_dissector()" to take a dissector handle, ratherGuy Harris1-3/+4
than a pointer to a dissector function, as an argument. This means that the conversation dissector is called through "call_dissector()", so the dissector itself doesn't have to worry about checking whether the protocol is enabled or setting "pinfo->current_proto", so get rid of the code that does that in conversation dissectors. Also, make the conversation dissectors static. Get rid of some direct calls to dissectors; replace them with calls through handles, and, again, get rid of code to check whether a protocol is enabled and set "pinfo->current_proto" where that code isn't needed. Make those dissectors static if they aren't already static. Add a routine "create_dissector_handle()" to create a dissector handle without registering it by name, if the dissector isn't used outside the module in which it's defined. svn path=/trunk/; revision=4281

2001-09-03Instead of having a single datum attached to a conversation, have a listGuy Harris1-3/+8
of protocol-id-plus-datum pairs, so that multiple protocols can attach information to the same conversation. Dissectors that attach information to a conversation should not assume that if they find a conversation it has one of its data attached to it; the conversation might've been created by another dissector. svn path=/trunk/; revision=3901
2001-06-10Rename the arguments and flags for the conversation routines, so as notGuy Harris1-20/+27
to imply that 1) conversations have source and destination addresses and ports - they don't (if they did, they'd be monologues, not conversations), they just have two address/port pairs for the two endpoints, with one or more of the address or port in the second pair possibly being wildcarded; 2) the first and second address or port argument to "find_conversation()" or "try_conversation_dissector()" have anything to do with the first or second address/port pair in a conversation - they don't, the two arguments to those routines are matched against *both* address/port pairs for a conversation; as otherwise people might think that they need to add flags to wildcard the first arguments "conversation_new()" or "find_conversation()" (they don't, they just have to pass the non-wildcarded address/port first and then pass the wildcarded one, even if that means passing the destination first and source second). svn path=/trunk/; revision=3537
2000-11-18Nobody calls "old_try_conversation_dissector()" orGuy Harris1-5/+1
"old_dissector_try_heuristic()" any more, as their users have all been tvbuffified - get rid of them. svn path=/trunk/; revision=2660
2000-10-21Wildcard matching is tricky - you have to try wildcarding both theGuy Harris1-3/+2
source *and* destination port and/or both the source *and* destination address passed to "find_conversation()", because the packet for which you're trying to find the conversation may be going in the opposite direction to the packet for which the conversation was originally created. Create different hash tables for wildcarded conversations, to reduce the number of "is this a wildcard?" tests done when doing hash lookups. This is sufficient to allow the TFTP dissector to use conversations rather than being special-cased in the UDP dissector, and may also be sufficient to handle a similar problem with SMTP (request goes from client IP X port Y to server IP Z's well-known port, reply comes back from some other port on server Z to client IP X port Y), but further use may reveal other changes that should be made. svn path=/trunk/; revision=2525
