2004-07-18Move dissectors to epan/dissectors directory.Gilbert Ramirez1-169/+0
Also move ncp222.py, x11-fields, process-x11-fields.pl, make-reg-dotc, and make-reg-dotc.py. Adjust #include lines in files that include packet-*.h files. svn path=/trunk/; revision=11410
2004-07-18Set the svn:eol-style property on all text files to "native", so thatGuy Harris1-1/+1
they have LF at the end of the line on UN*X and CR/LF on Windows; hopefully this means that if a CR/LF version is checked in on Windows, the CRs will be stripped so that they show up only when checked out on Windows, not on UN*X. svn path=/trunk/; revision=11400
2002-08-28Removed trailing whitespaces from .h and .c files using theJörg Mayer1-6/+6
winapi_cleanup tool written by Patrik Stridvall for the wine project. svn path=/trunk/; revision=6117
2002-08-02Replace the types from sys/types.h and netinet/in.h by their glib.hJörg Mayer1-5/+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. svn path=/trunk/; revision=5932
2002-01-21Include files from the "epan" directory and subdirectories thereof withGuy Harris1-2/+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/"). svn path=/trunk/; revision=4586
2001-12-20Set the PPP direction flag for transmitted or received PPP frames.Guy Harris1-1/+13
svn path=/trunk/; revision=4429
2001-12-10Move the pointer to the "column_info" structure in the "frame_data"Guy Harris1-9/+9
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. svn path=/trunk/; revision=4370
2001-12-03Make "dissector_add()", "dissector_delete()", and "dissector_change()"Guy Harris1-3/+7
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
2001-06-18From Joerg Mayer: explicitly fill in all members of aGuy Harris1-7/+7
"header_field_info" structure, including the ones that are later set by the routines to register fields. svn path=/trunk/; revision=3561
2001-03-30Call the dissector for PPP-in-HDLC-like-framing (RFC 1662) theGuy Harris1-5/+5
"ppp_hdlc" dissector, and call the dissector for "raw" PPP (just RFC 1661, no HDLC encapsulation) the "ppp" dissector. Have the common routine used by both those dissectors take the offset in the tvbuff of the PPP protocol field as an argument, rather than assuming that the protocol field begins at the beginning of the tvbuff, so we don't have to construct a new tvbuff in the PPP-in-HDLC-like-framing dissector. Use the PPP dissector, not the PPP-in-HDLC-like-framing dissector, for PPP over Frame Relay - there's no HDLC header in PPP over Frame Relay, at least according to http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120t/120t1/pppframe.htm svn path=/trunk/; revision=3208
2001-01-25Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="Guy Harris1-5/+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. "Tvbuffify" the Mobile IP dissector (it took old-style arguments, and then converted them into tvbuff arguments, so there wasn't much to do, other than to fix references to "fd" to refer to "pinfo->fd"). In the SCTP dissector, refer to the port type and source and destination ports through "pinfo" rather than through the global "pi", as it's a tvbuffified dissector. In the SMTP and Time Protocol dissectors, use "pinfo->match_port" rather than "TCP_PORT_SMTP" when checking whether the packet is a request or reply, just in case somebody makes a non-standard port be dissected as SMTP or Time. (Also, remove a bogus comment from the Time dissector; it was probably cut-and-pasted from the TFTP dissector.) svn path=/trunk/; revision=2938
2001-01-09Add an additional "protocol index" argument to "{old_}dissector_add()",Guy Harris1-2/+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....) 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
2000-11-29Wrap the dissect_fddi() call (with a 4th argument) withGilbert Ramirez1-3/+3
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. svn path=/trunk/; revision=2708
2000-11-19For each column, have both a buffer into which strings for that columnGuy Harris1-5/+5
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
2000-11-19Have the Etherenet and PPP dissectors register themselves, and haveGuy Harris1-5/+16
other dissectors call them through handles. Do the same for the "PPP payload" dissector, after tvbuffifying it. Tvbuffify the PPPoE dissector. Do the last little bit of tvbuffifying the L2TP dissector (it takes old-style arguments and immediately generates a tvbuff out of them; make it take new-style arguments). svn path=/trunk/; revision=2664
2000-08-20"ascend" was not working as display filter...Laurent Deniel1-2/+3
svn path=/trunk/; revision=2311
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
2000-05-31Add routines for adding items to a protocol tree that take arguments ofGuy Harris1-9/+9
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
2000-05-25Convert dissect_ppp() and friends to use tvbuffs.Gilbert Ramirez1-5/+2
(the ip_tcp_options stuff is still non-tvbuff until I convert ip and tcp). Add preliminary fix for Linux ISDN ippp devices (similar watch was posted to ethereal-users, but did not use tvbuffs). Change packet-raw.c to call capture_ppp()/dissect_ppp() in the case where the frame starts with FF:03. We had been calling capture_ip()/dissect_ip() at byte offset 4, but I think this is for historical reasons of packet-raw.c and packet-ip.c existing before packet-ppp.c. svn path=/trunk/; revision=1998
2000-05-19Add wtap-int.h. Move definitions relevant to the internal workins of wiretapGilbert Ramirez1-7/+7
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. svn path=/trunk/; revision=1989
2000-05-18Remove the "union pseudo_header" from the "frame_data" structure;Guy Harris1-10/+12
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). svn path=/trunk/; revision=1975
2000-05-16Convert Ethernet and Lucent/Ascend dissectors to use tvbuff.Gilbert Ramirez1-28/+34
Note in AUTHORS file that we use the exception module from kazlib. svn path=/trunk/; revision=1966
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
2000-03-27Change dissect_ppp() to accept offset.Gilbert Ramirez1-2/+2
Change GRE dissector to call dissect_ppp() instead of dissect_payload_ppp(). svn path=/trunk/; revision=1753
2000-02-15Create a header file for every packet-*.c file. Prune the packet.h file.Gilbert Ramirez1-1/+3
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. svn path=/trunk/; revision=1637
1999-11-16Replace the ETT_ "enum" members, declared in "packet.h", withGuy Harris1-3/+8
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

1999-10-16- replace proto_tree_add_item_format by proto_tree_add_item.Laurent Deniel1-15/+17
- add new filter fields. If someone has a captured file with this kind of packets, please sent it to me. svn path=/trunk/; revision=852
1999-10-12New proto_tree header_field_info stuff. Header_field_infos now containGilbert Ramirez1-4/+7
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
