2004-01-26Add a dissector table for LAPD SAPIs, and move the #defines for themguy1-25/+13
into "lapd_sapi.h". Use that to register the Q.931 dissector atop LAPD. From Rolf Fiedler: ISDN TEI management frame support. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@9864 f5534014-38df-0310-8fa8-9805f1628bb7
2004-01-18Add arguments to "dissect_xdlc_control()" to specify value_stringguy1-3/+3
tables, for use in the top-level item for the control field, for unnumbered frame function codes for commands and responses. If the argument is null, default to the standard tables. Use "dissect_xdlc_control()" and the #defines from "xdlc.h" for IrDA. Use the reported length rather than the data length in the IrDA dissector when iterating over the data in an IrDA packet. Make "dissect_xid()" update the column information as well as the protocol tree. Put the slot number into the protocol tree only for command frames - "the slot number field is undefined in discovery XID response frames", to quote the IrLAP spec. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@9713 f5534014-38df-0310-8fa8-9805f1628bb7
2004-01-03Have "dissect_xdlc_control()" take a pointer to a structure containingguy1-2/+89
pointers to hf_ values, so the subfields of the control field are put into the protocol tree as filterable items. Change the protocols that use it appropriately. Export "dissect_xdlc_control()" to plugins. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@9531 f5534014-38df-0310-8fa8-9805f1628bb7
2003-09-02Use "dissect_xdlc_control()" to dissect the control field of Frame Relayguy1-2/+2
packets that have one. Add an argument to "dissect_xdlc_control()" to indicate whether it should append the information to the Info field or just put it in the Info field. Use the #defines for the DLCI bitfields to extract the DLCI bits when constructing the DLCI. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@8335 f5534014-38df-0310-8fa8-9805f1628bb7
2003-01-07Note that we should handle LAPD traffic other than Q.931 traffic.guy1-2/+6
git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@6864 f5534014-38df-0310-8fa8-9805f1628bb7
2002-10-31To determine the direction of the traffic, use "pinfo->p2p_dir", ratherguy1-2/+3
than the p2p pseudo-header's "sent" field, in the LAPD dissector (the p2p pseudo-header isn't used for ISDN). Do something similar for the V.120 dissector (which currently will only be used in ISDN captures, but this makes it possible for it to handle other captures as well). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@6522 f5534014-38df-0310-8fa8-9805f1628bb7
2002-10-31Discard the WTAP_ENCAP_LAPD encapsulation type in favor of aguy1-6/+3
WTAP_ENCAP_ISDN encapsulation type, which includes a pseudo-header giving the direction (user-to-network or network-to-user) and the channel number. Add a new circuit type, using the ISDN channel number as the circuit ID. Add an ISDN dissector to put the direction and channel number into the protocol tree and to call the appropriate dissector for the payload based on the channel (LAPD for the D channel; V.120, PPP, or data for B channels, based on some heuristics). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@6521 f5534014-38df-0310-8fa8-9805f1628bb7
2002-08-28Removed trailing whitespaces from .h and .c files using thejmayer1-5/+5
winapi_cleanup tool written by Patrik Stridvall for the wine project. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@6117 f5534014-38df-0310-8fa8-9805f1628bb7
2002-08-02Replace the types from sys/types.h and netinet/in.h by their glib.hjmayer1-5/+1
equivalents for the toplevel directory. The removal of winsock2.h will hopefully not cause any problems under MSVC++, as those files using struct timeval still include wtap.h, which still includes winsock2.h. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@5932 f5534014-38df-0310-8fa8-9805f1628bb7

2002-01-21Include files from the "epan" directory and subdirectories thereof withguy1-2/+2
"epan/..." pathnames, so as to avoid collisions with header files in any of the directories in which we look (e.g., "proto.h", as some other package has its own "proto.h" file which it installs in the top-level include directory). Don't add "-I" flags to search "epan", as that's no longer necessary (and we want includes of "epan" headers to fail if the "epan/" is left out, so that we don't re-introduce includes lacking "epan/"). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4586 f5534014-38df-0310-8fa8-9805f1628bb7
2001-12-10Move the pointer to the "column_info" structure in the "frame_data"guy1-13/+13
structure to the "packet_info" structure; only stuff that's permanently stored with each frame should be in the "frame_data" structure, and the "column_info" structure is not guaranteed to hold the column values for that frame at all times - it was only in the "frame_data" structure so that it could be passed to dissectors, and, as all dissectors are now passed a pointer to a "packet_info" structure, it could just as well be put in the "packet_info" structure. That saves memory, by shrinking the "frame_data" structure (there's one of those per frame), and also lets us clean up the code a bit. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4370 f5534014-38df-0310-8fa8-9805f1628bb7
2001-12-03Make "dissector_add()", "dissector_delete()", and "dissector_change()"guy1-3/+5
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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4308 f5534014-38df-0310-8fa8-9805f1628bb7

2001-01-22Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="guy1-8/+5
statements. Move the setting of the Protocol column in the Appletalk ARP and IPX 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. Fix the registration of the IPX RIP dissector to use the right protocol ID. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2928 f5534014-38df-0310-8fa8-9805f1628bb7
2001-01-09Add an additional "protocol index" argument to "{old_}dissector_add()",guy1-2/+2
"{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....) git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2849 f5534014-38df-0310-8fa8-9805f1628bb7
2001-01-03Have "proto_register_protocol()" build a list of data structures forguy1-2/+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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2810 f5534014-38df-0310-8fa8-9805f1628bb7
2000-11-29Wrap the dissect_fddi() call (with a 4th argument) withgram1-3/+8
dissect_fddi_not_bitswapped() and dissect_fddi_bitswapped(), both of which use the standard 3-argument tvbuffified-dissector argument list. Add a dissector table called "wtap_encap" which is used to call dissectors from dissect_frame(). The switch() statement from this top-level dissector is removed. The link-layer dissectors register themselves with the "wtap_encap" dissector table. The dissectors are now static where possible. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2708 f5534014-38df-0310-8fa8-9805f1628bb7
2000-11-19For each column, have both a buffer into which strings for that columnguy1-6/+6
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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2670 f5534014-38df-0310-8fa8-9805f1628bb7
2000-11-16Tvbuffify the STP dissector, have it register itself and have the LLCguy1-3/+3
dissector call it through a handle, and make it static. Give "dissect_data()" an "offset" argument, so dissectors can use it to dissect part of the packet without having to cook up a new tvbuff. Go back to using "dissect_data()" to dissect the data in an IPP request. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2651 f5534014-38df-0310-8fa8-9805f1628bb7
2000-09-21Make sure to pass the sent/received direction from pppdump.c ingram1-8/+8
pseudo_header. Use generic "p2p_phdr" instead of "lapd_phdr". Modify toshiba.c and packet-lapd.c to take that into account. Add frame.p2p_dir, a filterable field, 0=sent, 1=recvd Make p2p_dir available in packe_info, as I think it will be needed in VJ COMP and UNCOMP dissection. Rename WTAP_ENCAP_TR to WTAP_ENCAP_TOKEN_RING. Mention pppd-log support in man page. Mention atmsnoop in README. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2455 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)guy1-3/+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()". 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 ofguy1-8/+8
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
2000-05-31Convert LAPD and V.120 dissector to use tvbuff. Convert xdlc dissector-helper,gram1-31/+30
too. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2030 f5534014-38df-0310-8fa8-9805f1628bb7
2000-05-29Add "tvb_reported_length()" to get the "reported length" of a tvbuffguy1-4/+6
(i.e., the amount of data that was in the packet, even if not all of it was captured), for use when dissecting packets containing data that fills the packet (we want the dissector to try to dissect all of it; if it runs past the end of the captured data, we want it to throw an exception so that we'll put a "Short Frame" note in the protocol tree). This means we always want a tvbuff to have a real reported length value, so we make it an unsigned integer, and don't bother checking it for -1, as it should never be -1. If the reported length passed in to "tvb_set_subset()" is -1, set the reported length to the reported length of the tvbuff of which the new tvbuff will be a subset minus the offset in that tvbuff of the subset, so that "-1" means "what's left of the packet after we chop off the header". This is necessary in order to ensure that all tvbuffs have a real reported length value. Have "dissect_packet()" set the reported length of the top-level tvbuff to the reported length of the frame, so that we start out with a tvbuff with a real reported length value. Have "tvb_offset_exists()" return FALSE if the offset is past the end of the tvbuff. If the offset passed to it is postitive, have "compute_offset_length()" check for that it's not more than one byte past the end of the tvbuff - if it's just past the end, we don't want the check to fail, as we don't want attempts to create a subset tvbuff containing zero bytes to fail; that would be done if a captured packet was all header and no payload, and we'd want the dissector of the payload, not the dissector of the header, to throw an exception, as the problem isn't with the protocol for the header, it's with the protocol for the payload. Convert the ATM dissector, the SSCOP dissector, the Q.2931 dissector, and the Q.931 dissector to use tvbuffs. Make the LAPD dissector set up a tvbuff for the Q.931 dissector (it's not converted yet). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2023 f5534014-38df-0310-8fa8-9805f1628bb7
2000-05-19Add wtap-int.h. Move definitions relevant to the internal workins of wiretapgram1-2/+2
to that file, leave public definitions in wtap.h. Rename "union pseudo_header" to "union wtap_pseudo_header". Make the wtap_pseudo_header pointer available in packet_info struct. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1989 f5534014-38df-0310-8fa8-9805f1628bb7
2000-05-18Remove the "union pseudo_header" from the "frame_data" structure;guy1-3/+5
there's no need to keep it around in memory - when the frame data is read in when handing a frame, read in the information, if any, necessary to reconstruct the frame header, and reconstruct it. This saves some memory. This requires that the seek-and-read function be implemented inside Wiretap, and that the Wiretap handle remain open even after we've finished reading the file sequentially. This also points out that we can't really do X.25-over-Ethernet correctly, as we don't know where the direction (DTE->DCE or DCE->DTE) flag is stored; it's not clear how the Ethernet type 0x0805 for X.25 Layer 3 is supposed to be handled in any case. We eliminate X.25-over-Ethernet support (until we find out what we're supposed to do). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1975 f5534014-38df-0310-8fa8-9805f1628bb7
2000-05-11Add tvbuff class.gram1-8/+8
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
2000-02-15Create a header file for every packet-*.c file. Prune the packet.h file.gram1-1/+2
This change allows you to add a new packet-*.c file and not cause a recompilation of everything that #include's packet.h Add the plugin_api.[ch] files ot the plugins/Makefile.am packaging list. Add #define YY_NO_UNPUT 1 to the lex source so that the yyunput symbol is not defined, squelching a compiler complaint when compiling the generated C file. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1637 f5534014-38df-0310-8fa8-9805f1628bb7
2000-01-24xDLC frames other than I and UI frames may have a payload, e.g. TESTguy1-3/+4

1999-11-16Replace the ETT_ "enum" members, declared in "packet.h", withguy1-12/+23
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
