2000-11-17Add #include <string.h>, to get prototypes for mem* and str* functions.gram1-1/+2
git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2654 f5534014-38df-0310-8fa8-9805f1628bb7
2000-08-13Add the "Edit:Protocols..." feature which currently only implementsdeniel1-1/+3
the following: It is now possible to enable/disable a particular protocol decoding (i.e. the protocol dissector is void or not). When a protocol is disabled, it is displayed as Data and of course, all linked sub-protocols are disabled as well. Disabling a protocol could be interesting: - in case of buggy dissectors - in case of wrong heuristics - for performance reasons - to decode the data as another protocol (TODO) Currently (if I am not wrong), all dissectors but NFS can be disabled (and dissectors that do not register protocols :-) I do not like the way the RPC sub-dissectors are disabled (in the sub-dissectors) since this could be done in the RPC dissector itself, knowing the sub-protocol hfinfo entry (this is why, I've not modified the NFS one yet). Two functions are added in proto.c : gboolean proto_is_protocol_enabled(int n); void proto_set_decoding(int n, gboolean enabled); and two MACROs which can be used in dissectors: OLD_CHECK_DISPLAY_AS_DATA(index, pd, offset, fd, tree) CHECK_DISPLAY_AS_DATA(index, tvb, pinfo, tree) See also the XXX in proto_dlg.c and proto.c around the new functions. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2267 f5534014-38df-0310-8fa8-9805f1628bb7
2000-08-07Allow either old-style (pre-tvbuff) or new-style (tvbuffified)guy1-5/+5
dissectors to be registered as dissectors for particular ports, registered as heuristic dissectors, and registered as dissectors for conversations, and have routines to be used both by old-style and new-style dissectors to call registered dissectors. Have the code that calls those dissectors translate the arguments as necessary. (For conversation dissectors, replace "find_conversation_dissector()", which just returns a pointer to the dissector, with "old_try_conversation_dissector()" and "try_conversation_dissector()", which actually call the dissector, so that there's a single place at which we can do that translation. Also make "dissector_lookup()" static and, instead of calling it and, if it returns a non-null pointer, calling that dissector, just use "old_dissector_try_port()" or "dissector_try_port()", for the same reason.) This allows some dissectors that took old-style arguments and immediately translated them to new-style arguments to just take new-style arguments; make them do so. It also allows some new-style dissectors not to have to translate arguments before calling routines to look up and call dissectors; make them not do so. Get rid of checks for too-short frames in new-style dissectors - the tvbuff code does those checks for you. Give the routines to register old-style dissectors, and to call dissectors from old-style dissectors, names beginning with "old_", with the routines for new-style dissectors not having the "old_". Update the dissectors that use those routines appropriately. Rename "dissect_data()" to "old_dissect_data()", and "dissect_data_tvb()" to "dissect_data()". git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2218 f5534014-38df-0310-8fa8-9805f1628bb7
2000-05-31Add routines for adding items to a protocol tree that take arguments ofguy1-2/+2
a particular type, rather than taking a varargs list, along the lines of the "proto_tree_add_XXX_format()" routines. Replace most calls to "proto_tree_add_item()" and "proto_tree_add_item_hidden()" with calls to those routines. Rename "proto_tree_add_item()" and "proto_tree_add_item_hidden()" to "proto_tree_add_item_old()" and "proto_tree_add_item_hidden_old()", and add new "proto_tree_add_item()" and "proto_tree_add_item_hidden()" routines that don't take the item to be added as an argument - instead, they fetch the argument from the packet whose tvbuff was handed to them, from the offset handed to them. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2031 f5534014-38df-0310-8fa8-9805f1628bb7
2000-05-11Add tvbuff class.gram1-16/+16
Add exceptions routines. Convert proto_tree_add_*() routines to require tvbuff_t* argument. Convert all dissectors to pass NULL argument ("NullTVB" macro == NULL) as the tvbuff_t* argument to proto_tree_add_*() routines. dissect_packet() creates a tvbuff_t, wraps the next dissect call in a TRY block, will print "Short Frame" on the proto_tree if a BoundsError exception is caught. The FDDI dissector is converted to use tvbuff's. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1939 f5534014-38df-0310-8fa8-9805f1628bb7
2000-04-14RFC 1058, on RIP V1, says:guy1-2/+10
Specific queries and debugging requests may be sent from ports other than 520, but they are directed to port 520 on the target machine. and RFC 2453, on RIP V2, says: Specific queries may be sent from ports other than the RIP port, but they must be directed to the RIP port on the target machine. so there is no requirement that RIP packets have 520 as both source and destination port numbers. It's therefore OK to register it as the dissector for UDP port 520 - no need to handle it specially in the UDP dissector as a reminder to make it check both source and destination ports - so we do so. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1855 f5534014-38df-0310-8fa8-9805f1628bb7
1999-11-16Replace the ETT_ "enum" members, declared in "packet.h", withguy1-4/+12
dynamically-assigned "ett_" integer values, assigned by "proto_register_subtree_array()"; this: obviates the need to update "packet.h" whenever you add a new subtree type - you only have to add a call to "proto_register_subtree_array()" to a "register" routine and an array of pointers to "ett_", if they're not already there, and add a pointer to the new "ett_" variable to the array, if they are there; would allow run-time-loaded dissectors to allocate subtree types when they're loaded. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1043 f5534014-38df-0310-8fa8-9805f1628bb7
1999-08-26Convert a bunch of uses of "fd->cap_len" to use "pi.captured_len" (or toguy1-3/+3
use END_OF_FRAME), so that they don't look at stuff in an IP datagram past the end of the IP datagram (i.e., frame padding). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@584 f5534014-38df-0310-8fa8-9805f1628bb7

1999-07-29Made the protocol (but not the fields) use the new proto_tree routine,gram1-2/+15
allowing users to filter on the existence of these protocols. I also added packet-clip.c to the Nmake makefile. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@402 f5534014-38df-0310-8fa8-9805f1628bb7
1999-07-07Created a new protocol tree implementation and a new display filtergram1-22/+19
mechanism that is built into ethereal. Wiretap is now used to read all file formats. Libpcap is used only for capturing. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@342 f5534014-38df-0310-8fa8-9805f1628bb7
1999-03-23Removed all references to gtk objects from packet*.[ch] files. They nowgram1-36/+33
reference the protocol tree with struct proto_tree and struct proto_item objects. That way, the packet decoding source code file can be used with non-gtk packet decoders, like a curses-based ethereal, e.g. I also re-arranged some of the information in packet.h to more appropriate places (like other packet-*.[ch] files). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@223 f5534014-38df-0310-8fa8-9805f1628bb7

1998-11-17* Added column formatting functionality.gerald1-5/+5
* Added check_col(), add_col_str() and add_col_fmt() to replace references to ft->win_info. * Added column prefs handling code. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@97 f5534014-38df-0310-8fa8-9805f1628bb7
1998-09-27Merged in a _huge_ patch from Guy Harris. It adds a time stap column,gerald1-5/+5
generalizes the column printing code, adds a "frame" tree item to the tree view, and fixes a bunch of miscellaneous coding bugs. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@31 f5534014-38df-0310-8fa8-9805f1628bb7
