2001-01-03Have "proto_register_protocol()" build a list of data structures forGuy Harris1-2/+3
protocols, in addition to adding structures to the list of filterable fields. Give it an extra argument that specifies a "short name" for the protocol, for use in such places as pinfo->current_proto; the dialog box for constructing filters; the preferences tab for the protocol; and so on (although we're not yet using it in all those places). Make the preference name that appears in the preferences file and the command line for the DIAMETER protocol "diameter", not "Diameter"; the convention is that the name in question be all-lower-case. Make some routines and variables that aren't exported static. Update a comment in the ICP dissector to make it clear that the dissector won't see fragments other than the first fragment of a fragmented datagram. svn path=/trunk/; revision=2810
2000-12-28Always put the packet type in the Info column.Guy Harris1-4/+3
svn path=/trunk/; revision=2789
2000-12-27Tvbuffify the RIP and OSPF dissectors.Guy Harris1-645/+742
Change them to use facilities in Ethereal that were probably not present when they were originally written, e.g. routines to fetch 24-bit integers and to dump a bunch of raw bytes in hex. Redo them to extract data from the packet as they dissect it, rather than extracting an entire data structure at once; that way, it may be able to dissect a structure not all of which is in the packet. Dissect a bit more of the type-of-service metrics etc. in OSPF packets. Make "tvb_length_remaining()" return a "gint", not a "guint"; it returns -1 if the offset is past the end of the tvbuff. Add a "tvb_reported_length_remaining()" routine, similar to "tvb_length_remaining()". Use it instead of just subtracting an offset from "tvb_reported_length()". svn path=/trunk/; revision=2787
2000-12-14Check the checksum on OSPF packets, if possible.Guy Harris1-3/+44
svn path=/trunk/; revision=2760
2000-11-19For each column, have both a buffer into which strings for that columnGuy Harris1-2/+2
can be put, and a pointer to the string for the column, which might or might not point to that buffer. Add a routine "col_set_str()", which sets the string for the column to the string passed to it as an argument; it should only be handed a static string (a string constant would be ideal). It doesn't do any copying, so it's faster than "col_add_str()". Make the routines that append to columns check whether the pointer to the string for the column points to the buffer for the column and, if not, copy the string for the column to the buffer for the column so that you can append to it (so you can use "col_set_str()" and then use "col_append_str()" or "col_append_fstr()"). Convert a bunch of "col_add_str()" calls that take a string constant as an argument to "col_set_str()" calls. Convert some "col_add_fstr()" calls that take a string constant as the only argument - i.e., the format string doesn't have any "%" slots into which to put strings for subsequent arguments to "col_set_str()" calls (those calls are just like "col_add_str()" calls). Replace an END_OF_FRAME reference in a tvbuffified dissector with a "tvb_length(tvb)" call. svn path=/trunk/; revision=2670
2000-09-13Changes from Craig Metz to:Guy Harris1-2/+6
decode type 7 LSAs (NSSA AS external); print the LS checksum as a four digit hexadecimal number. svn path=/trunk/; revision=2425
2000-08-13Add the "Edit:Protocols..." feature which currently only implementsLaurent Deniel1-1/+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. svn path=/trunk/; revision=2267
2000-08-07Allow either old-style (pre-tvbuff) or new-style (tvbuffified)Guy Harris1-3/+3
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()". svn path=/trunk/; revision=2218
2000-07-14Enhancements/fixed to OSPF from Michael Rozhavsky:Guy Harris1-3/+9
1) DD flags in Database Description packets were translated incorrectly; 2) Summary-LSA metric was not displayed. svn path=/trunk/; revision=2136
2000-05-31Add routines for adding items to a protocol tree that take arguments ofGuy Harris1-2/+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. svn path=/trunk/; revision=2031
2000-05-11Add tvbuff class.Gilbert Ramirez1-114/+114
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. svn path=/trunk/; revision=1939
2000-04-16Register an "ip.proto" dissector table for IPv4, and have dissectors forGuy Harris1-8/+28
protocols that run inside IPv4 register themselves with it using "dissector_add()". Make various dissectors static if they can be, and get rid of any header files that no longer contain any information as a result of that change. svn path=/trunk/; revision=1870
2000-03-14Fix some errors discovered by making GCC do format string/argumentGuy Harris1-4/+4
cross-checking, and by replacing "proto_tree_add_item_format()" by multiple routines to add items of various types. Make the arguments of "proto_tree_add_bytes_format()" and "proto_tree_add_string_format()" that specify the bytes or the string be "const" pointers, so that one can pass a "const" pointer without complaints from the compiler. Squelch a (bogus, but the compiler isn't in a position to know that) complaint about an uninitialized variable. svn path=/trunk/; revision=1716
2000-03-09Support for MultiProtocol Label Switching (MPLS). The following supportAshok Narayanan1-4/+259
is being added - MPLS Traffic Engineering extensions for RSVP - MPLS-encapsulated IP packets on Ethernet - OSPF Extensions for MPLS (including generic opaque LSA support for OSPF) THe following features will be committed at a later date (if I get around to writing them :-) - Label Distribution Protocol (LDP) - IS-IS Extensions for MPLS svn path=/trunk/; revision=1707
2000-03-07Fix some "proto_tree_add_text()" calls.Guy Harris1-3/+3
svn path=/trunk/; revision=1696
2000-02-11Fix from Nick Amato for a typo - "Link", in "Link State", shouldn't haveGuy Harris1-2/+2
an "e" in it. svn path=/trunk/; revision=1618
1999-11-17Typo fixes, and fix to bug wherein when Ethereal sees a Network-LSA itGuy Harris1-4/+6
does not stop dissecting the LSA until it hits the end of the packet, from Heikki Vatiainen. svn path=/trunk/; revision=1049
1999-11-16Replace the ETT_ "enum" members, declared in "packet.h", withGuy Harris1-8/+26
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. svn path=/trunk/; revision=1043
1999-10-27Get rid of a presumed debugging "printf()".Guy Harris1-2/+1
svn path=/trunk/; revision=934
1999-10-19Added Tony Hart's <thart@avici.com> patch to dissect MD5 authenticationGilbert Ramirez1-3/+28
data in OSPF. (corrected copy) svn path=/trunk/; revision=889
1999-08-26Convert a bunch of uses of "fd->cap_len" to use "pi.captured_len" (or toGuy Harris1-11/+11
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). svn path=/trunk/; revision=584
1999-07-29Made the protocol (but not the fields) use the new proto_tree routine,Gilbert Ramirez1-2/+15
allowing users to filter on the existence of these protocols. I also added packet-clip.c to the Nmake makefile. svn path=/trunk/; revision=402
1999-07-07Created a new protocol tree implementation and a new display filterGilbert Ramirez1-85/+78
mechanism that is built into ethereal. Wiretap is now used to read all file formats. Libpcap is used only for capturing. svn path=/trunk/; revision=342
1999-03-23Removed all references to gtk objects from packet*.[ch] files. They nowGilbert Ramirez1-113/+117
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). svn path=/trunk/; revision=223
1999-01-17Clean up some output lines, and show the checksum value on the line forGuy Harris1-5/+6
the packet checksum. svn path=/trunk/; revision=170
1998-11-17* Added column formatting functionality.Gerald Combs1-5/+6
* Added check_col(), add_col_str() and add_col_fmt() to replace references to ft->win_info. * Added column prefs handling code. svn path=/trunk/; revision=97
1998-10-20 Add a "val_to_str()" routine that calls "match_strval()" and, ifGuy Harris1-24/+16
it returns NULL, formats the value with the format passed in as an argument, and returns a pointer to that static buffer. Change several "match_strval()" calls to use "val_to_str()". In "dissect_ospf()", use "match_strval()" to look up the packet type, and use "Unknown" if it doesn't find a match. svn path=/trunk/; revision=66
1998-10-13Squelch a number of "-Wall" errors by:Guy Harris1-2/+2
1) renaming "snprintf.h" to "snprintf-imp.h" (it contains stuff used by the "snprintf()" *implementation*, but not stuff it *exports*); 2) creating a new "snprintf.h" to declare "vsnprintf()" and "snprintf()"; 3) removing an unused variable; 4) fixing a call to "add_item_to_tree()" to handle the possibility of "ntohl()" returning a "long" rather than an "int". svn path=/trunk/; revision=47
