2001-12-03Make "dissector_add()", "dissector_delete()", and "dissector_change()"Guy Harris1-9/+8
take a dissector handle as an argument, rather than a pointer to a dissector function and a protocol ID. Associate dissector handles with dissector table entries. svn path=/trunk/; revision=4308
2001-11-14Make the RADIUS dissector handle bogus AVPs (AVPs with a length lessGuy Harris1-5/+12
than the size of the AVP header) a bit better. svn path=/trunk/; revision=4203

2001-06-18Don't list the attribute-value pairs if the length field of the packetGuy Harris1-9/+11
says there aren't any (i.e., if the length field minus the size of the stuff before the AVP's is less than or equal to 0). svn path=/trunk/; revision=3568
2001-06-18From Joerg Mayer: explicitly fill in all members of aGuy Harris1-4/+4
"header_field_info" structure, including the ones that are later set by the routines to register fields. svn path=/trunk/; revision=3561

2001-06-05Juniper Networks vendor ID in RADIUS dissector, from Hannes Gredler.Guy Harris1-1/+2
svn path=/trunk/; revision=3516
2001-03-13Make tvb_get_ptr() return 'const guint8*', and clean up all theGilbert Ramirez1-3/+3
usages of tvb_get_ptr(). packet-ieee80211.c still has one bad usage, in which it *does* modify the tvbuff's data. svn path=/trunk/; revision=3128
2001-02-20In the DIAMETER dissector, clear the Info column before fetchingGuy Harris1-80/+75
anything from the packet, so that if we throw an exception before setting the Info column, it doesn't have stuff left over from the previous dissector. Tvbuffify the RADIUS dissector. svn path=/trunk/; revision=3055
2001-02-19New tvbuffified DIAMETER dissector, from David Frascone.Guy Harris1-8/+1
It doesn't do DIAMETER-over-UDP, so the RADIUS dissector no longer checks for DIAMETER packets and calls the DIAMETER dissector if it finds one. svn path=/trunk/; revision=3049
2001-02-05Fix up some MSVC complaints about (narrowing) type conversions byGuy Harris1-2/+2
widening formal arguments or narrowing variables passed as actual arguments. svn path=/trunk/; revision=2993
2001-01-22Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="Guy Harris1-3/+1
statements. Move the setting of the Protocol column in various dissectors before anything is fetched from the packet, and also clear the Info column at that point in those and some other dissectors, so that if an exception is thrown, the columns don't reflect the previous protocol. svn path=/trunk/; revision=2932
2001-01-16Do not use "match_strval()" unless you're prepared to check whether itGuy Harris1-3/+3
returns NULL and do something appropriate if it does so; instead, use "val_to_str()", and let *it* worry about the value passed to it not having a corresponding string. svn path=/trunk/; revision=2908
2001-01-09Add an additional "protocol index" argument to "{old_}dissector_add()",Guy Harris1-5/+9
"{old_}heur_dissector_add()", "{old_}conv_dissector_add()", and "register_dissector()", so that an entry in those tables has associated with it the protocol index of the protocol the dissector handles (or -1, if there is no protocol index for it). This is for future use in a number of places. (Arguably, "proto_register_protocol()" should take a dissector pointer as an argument, but 1) it'd have to handle both regular and heuristic dissectors; 2) making it take either a "dissector_t" or a union of that and a "heur_dissector_t" introduces some painful header-file interdependencies so I'm punting on that for now. As with other Ethereal internal APIs, these APIs are subject to change in the future, at least until Ethereal 1.0 comes out....) svn path=/trunk/; revision=2849
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
2000-11-28The SMI Network Management Private Enterprise Code for Ascend is 529,Guy Harris1-2/+10
not 123 (123 is Newbridge Networks); update the list of RADIUS vendor IDs, and put in a comment before that list indicating that RADIUS vendor IDs are just SMI Network Management Private Enterprise Codes and giving the URL of the IANA list of enterprise codes. svn path=/trunk/; revision=2703
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
2000-11-17Add #include <string.h>, to get prototypes for mem* and str* functions.Gilbert Ramirez1-1/+2
svn path=/trunk/; revision=2654
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 Harris1-5/+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()". svn path=/trunk/; revision=2218
2000-07-30"rd_match_strval()" just does what "val_to_str()" does with a formatGuy Harris1-9/+2
argument of "Undefined(%d)"; just use "val_to_str()" (and use "%u" rather than "%d", as the value passed to it is unsigned). svn path=/trunk/; revision=2177

svn path=/trunk/; revision=2176
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 Ramirez1-10/+10
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
2000-04-08Move calls to "dissector_add()" out of the register routines for TCP andGuy Harris1-2/+16
UDP and into the handoff registration routines for the protocols in question. Make the dissectors for those protocols static if they're not called outside the dissector's source file. Get rid of header files if all they did was declare dissectors that are now static; remove declarations of now-static dissectors from header files that do more than just declare the dissector. svn path=/trunk/; revision=1823

2000-03-12Break proto_tree_add_item_format() into multiple functions:Gilbert Ramirez1-4/+4
proto_tree_add_protocol_format() proto_tree_add_uint_format() proto_tree_add_ipxnet_format() proto_tree_add_ipv4_format() proto_tree_add_ipv6_format() proto_tree_add_bytes_format() proto_tree_add_string_format() proto_tree_add_ether_format() proto_tree_add_time_format() proto_tree_add_double_format() proto_tree_add_boolean_format() If using GCC 2.x, we can check the print-format against the variable args passed in. Regardless of compiler, we can now check at run-time that the field type passed into the function corresponds to what that function expects (FT_UINT, FT_BOOLEAN, etc.) Note that proto_tree_add_protocol_format() does not require a value field, since the value of a protocol is always NULL. It's more intuitive w/o the vestigial argument. Fixed a proto_tree_add_item_format-related bug in packet-isis-hello.c Fixed a variable usage bug in packet-v120.c. (ett_* was used instead of hf_*) Checked in Guy's fix for the function declearation for proto_tree_add_text() and proto_tree_add_notext(). svn path=/trunk/; revision=1713
1999-12-02Fix infinite loop on short packets or bad data in radius dissector.Gilbert Ramirez1-1/+7
Problem reported by Arni Raghu <arni@caip.rutgers.edu>. svn path=/trunk/; revision=1185
1999-11-16Replace the ETT_ "enum" members, declared in "packet.h", withGuy Harris1-8/+16
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
1999-10-12New proto_tree header_field_info stuff. Header_field_infos now containGilbert Ramirez1-4/+9
the base for numbers to be displayed in, bitmasks for bitfields, and blurbs (which are one or two sentences describing the field). proto_tree_add*() routines now automatically handle bitfields. You tell it which header field you are adding, and just pass it the value of the entire field, and the proto_tree routines will do the masking and shifting for you. This means that bitfields are more naturally filtered via dfilter now. Added Phil Techau's support for signed integers in dfilters/proto_tree. Added the beginning of the SNA dissector. It's not complete, but I'm committing it now because it has example after example of how to use bitfields with the new header_field_info struct and proto_tree routines. It was the impetus to change how header_field_info works. svn path=/trunk/; revision=815
1999-08-03Checked in Johan's Updated RADIUS dissector which uses the new proto_treeGilbert Ramirez1-19/+58
implementation. svn path=/trunk/; revision=425
1999-07-13Added support for compiling on win32 with Visual C and 'nmake'. It compiles,Gilbert Ramirez1-3/+2
but does not link. Perhaps someone who understands the MS tools can help out. I made it link a few months ago, but with different version of glib/gtk+. I can't remember how I made it link. Most of the compatibility issues were resolved with adding #ifdef HAVE_UNISTD_H the the source code. Please be sure to add this to all future code. svn path=/trunk/; revision=359
1999-07-08Added Johan's RADIUS dissector, finally. I modified it to fit in with theGilbert Ramirez1-0/+589
new proto_tree routines. I also removed the check for lex and yacc from wiretap's configure script. The IP dissector now uses proto_register_field_array(). svn path=/trunk/; revision=348
