2002-08-28Removed trailing whitespaces from .h and .c files using theJörg Mayer1-130/+130
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 Mayer1-16/+8
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
2002-06-29Use "%u" to print unsigned quantities.Guy Harris1-22/+22
svn path=/trunk/; revision=5801
2002-06-29From Didier Gautheron:Guy Harris1-25/+388
Add Zone Information Protocol support. Rename "ddp.dst.socket" and "ddp.src.socket" to "ddp.dst_socket" and "ddp.src_socket", as the socket number is no longer considered part of the DDP address. svn path=/trunk/; revision=5800
2002-06-28From Didier Gautheron: move port number from AppleTalk addresses toGuy Harris1-7/+32
separate column, and put in hidden fields for AppleTalk source and destination addresses. svn path=/trunk/; revision=5778
2002-06-25Fixed incorrect format string.Tim Potter1-2/+2
svn path=/trunk/; revision=5760
2002-06-20From Didier Gautheron: assorted small fixes, more AFP calls, and DSI/ASPGuy Harris1-1/+2
error code in the Info column. svn path=/trunk/; revision=5712
2002-06-07Add "show_fragment_seq_tree()", which is like "show_fragment_tree()",Guy Harris1-64/+18
but for stuff reassembled with "fragment_add_seq()" or "fragment_add_seq_check()". Add a "fragment tag" string to the "fragment_items", so that packets with fragmentation errors can be properly flagged as having "Illegal fragments" or "Illegal segments" depending on the term used with the protocol in question. Make all the dissectors that can use "show_fragment_tree()" or "show_fragment_seq_tree()", and don't already use them, do so. svn path=/trunk/; revision=5644
2002-06-04Get rid of the "data_src" member of the "frame_data" structure; put itGuy Harris1-2/+2
in the "packet_info" structure instead, as we don't need a pointer for every single frame in the capture file, just for each frame for which we currently have an open "epan_dissect_t". svn path=/trunk/; revision=5614
2002-05-10From Joerg Mayer: make a pile of stuff not used outside one source fileGuy Harris1-2/+2
static, and add a new "packet-data.h" to declare "proto_data". Display escape sequences in octal in the IAPP dissector, as is now done in the RADIUS dissector. svn path=/trunk/; revision=5441
2002-05-08From Didier Gautheron:Guy Harris1-4/+49
DSI and ASP updates to better handle addresses in replies. Dissect DSI "open session" and "attention" messages. svn path=/trunk/; revision=5420
2002-05-03From Didier Gautheron:Guy Harris1-47/+532
afp : more calls. asp : move release transaction to atp. dissect asp call. fix a bug with transaction handling (conversation +tid are not enough as key ). atp : deal with one packet transaction without ATP_EOM. dsi: safeguard against overflow for unreassembled packet. more flags decoded. Update the "packet-atalk.c" comment to reflect all the protocols in it. svn path=/trunk/; revision=5376

column. svn path=/trunk/; revision=5328
2002-04-30From Didier Gautheron:Guy Harris1-25/+136
more calls supported in AFP; ATP desegmentation; show the name for NBP function 1 (broadcast request); "get status" reply for DSI. svn path=/trunk/; revision=5316
2002-04-28Pass even zero-length DSI and ASP "command" messages to the AFPGuy Harris1-8/+5
dissector, so it can show them as replies. Put the command code into the protocol tree for replies. Fix some additional AFP function names to match the names in the AFP spec. svn path=/trunk/; revision=5279
2002-04-28Updates from Didier Gautheron:Guy Harris1-2/+2
More calls, more fields, and other updates, for AFP. Decode the error code for DSI. Also, have separate fields for the code field in DSI when it's a data offset and when it's an error code. svn path=/trunk/; revision=5270
2002-04-26It's the AppleTalk Session Protocol, not the AppleTalk Stream Protocol.Guy Harris1-49/+72
Show the flag bits in the ATP "Control information" byte as individual Booleans, and show the TRel timeout indicator if the packet is a TReq with XO set. Clean up whitespace. svn path=/trunk/; revision=5256

2002-04-24From Joerg Mayer: get rid of extra arguments to capture routines.Guy Harris1-2/+2
svn path=/trunk/; revision=5233
2002-01-21Include files from the "epan" directory and subdirectories thereof withGuy Harris1-3/+3
"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
2002-01-20Allow a length of -1 to be specified when adding FT_NONE and FT_PROTOCOLGuy Harris1-6/+4
items to the protocol tree; it's interpreted as "the rest of the data in the tvbuff". This can be used if 1) the item covers the entire packet or the remaining payload in the packet or 2) the item's length won't be known until it's dissected, and will be then set with "proto_item_set_len()" - if an exception is thrown in the dissection, it means the item ran *past* the end of the tvbuff, so saying it runs to the end of the tvbuff is reasonable. Convert a number of "proto_tree_add_XXX()" calls using "tvb_length_remaining()", values derived from the result of "tvb_length()", or 0 (in the case of items whose length is unknown) to use -1 instead (using 0 means that if an exception is thrown, selecting the item highlights nothing; using -1 means it highlights all the data for that item that's available). In some places where "tvb_length()" or "tvb_length_remaining()" was used to determine how large a packet is, use "tvb_reported_length()" or "tvb_reported_length_remaining()", instead - the first two calls indicate how much captured data was in the packet, the latter two calls indicate how large the packet actually was (and the fact that using the latter could cause BoundsError exceptions to be thrown is a feature - if such an exception is thrown, the frame really *was* short, and it should be tagged as such). Replace some "proto_tree_add_XXX()" calls with equivalent "proto_tree_add_item()" calls. Fix some indentation. svn path=/trunk/; revision=4578
2001-12-10Move the pointer to the "column_info" structure in the "frame_data"Guy Harris1-37/+37
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
2001-12-08Attach a descriptive name field type and base to dissector tables; thatGuy Harris1-2/+3
specifies how the selector values used as keys in those tables are to be displayed, and the title to use when displaying the table. Use that information in the code to display the initial and current entries of various dissector tables. Have the dissector for BACnet APDUs register itself by name, and have the BACnet NPDU dissector call it iff the BAC_CONTROL_NET bit isn't set, rather than doing it with a dissector table. svn path=/trunk/; revision=4358
2001-12-03Make "dissector_add()", "dissector_delete()", and "dissector_change()"Guy Harris1-9/+25
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
2001-11-30Add support for LocalTalk Link Access Protocol.Guy Harris1-2/+156
Rename WTAP_ENCAP_PRISM to WTAP_ENCAP_PRISM_HEADER, to match DLT_PRISM_HEADER. Add in missing capture support for WTAP_ENCAP_PRISM_HEADER when capturing with "pcap_open_live()" rather than reading the capture from a pipe. svn path=/trunk/; revision=4299

2001-06-18From Joerg Mayer: explicitly fill in all members of aGuy Harris1-30/+30
"header_field_info" structure, including the ones that are later set by the routines to register fields. svn path=/trunk/; revision=3561

2001-04-23Get rid of END_OF_FRAME references in tvbuffified dissectors.Guy Harris1-2/+3
svn path=/trunk/; revision=3364
2001-03-22Move appletalk- and sna-related address routines out of the dissectorsGilbert Ramirez1-19/+2
and into epan. svn path=/trunk/; revision=3160
2001-03-15Add a new Wiretap encapsulation type for Cisco HDLC. Map the NetBSDGuy Harris1-1/+2
DLT_HDLC to it. Make a separate dissector for Cisco HDLC, and add a dissector for Cisco SLARP. Have the PPP dissector call the Cisco HDLC dissector if the address field is the Cisco HDLC unicast or multicast address. Use the Cisco HDLC dissector for the Cisco HDLC Wiretap encapsulation type. Add a new dissector table "chdlctype", for Cisco HDLC packet types (they're *almost* the same as Ethernet types, but 0x8035 is SLARP, not Reverse ARP, and 0x2000 is the Cisco Discovery protocol, for example), replacing "fr.chdlc". Have a "chdlctype()" routine, similar to "ethertype()", used both by the Cisco HDLC and Frame Relay dissectors. Have a "chdlc_vals[]" "value_string" table for Cisco HDLC types and protocol names. Split the packet type field in the Frame Relay dissector into separate SNAP and Cisco HDLC fields, and give them the Ethernet type and Cisco HDLC type "value_string" tables, respectively. svn path=/trunk/; revision=3133
2001-01-22Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="Guy Harris1-24/+17
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. Make the IP dissector static, as it's called only via dissector tables or dissector handles. Also make the "dissect the TOS field as the DiffServ DS field" flag static, as it's not referred to outside of "packet-ip.c". In the NCP dissector, refer to the port type through "pinfo" rather than through the global "pi", as it's a tvbuffified dissector. svn path=/trunk/; revision=2929
2001-01-09Add an additional "protocol index" argument to "{old_}dissector_add()",Guy Harris1-7/+7
"{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 Harris1-5/+5
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
2000-11-19For 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
2000-11-19The source operand of "SET_ADDRESS()" has to be static, as a pointer toGuy Harris1-2/+2
it is saved. svn path=/trunk/; revision=2669
2000-11-17Give the "null" link-layer header dissector a dissector table, and putGuy Harris1-2/+4
the BSD AF_ type values it uses into an "aftypes.h" header file for dissectors that register themselves in that dissector table include. svn path=/trunk/; revision=2653
2000-11-16Tvbuffify the STP dissector, have it register itself and have the LLCGuy Harris1-2/+2
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. svn path=/trunk/; revision=2651
2000-11-13Use "tvb_offset_exists()" rather than "tvb_length_remaining()" to checkGuy Harris1-2/+2
whether there's any data left in the tvbuff starting at a specified offset. svn path=/trunk/; revision=2636
2000-11-13Tvbuffify the AppleTalk dissectors.Guy Harris1-186/+213
Dissect RTMP requests, as well as RTMP data packets. Call it "Routing Table Maintenance Protocol", not just "Routing Table". Print unsigned quantities with "%u", not "%d". Correctly handle extended vs. non-extended networks in RTMP data packets, as per *Inside AppleTalk(R), Second Edition*. svn path=/trunk/; revision=2627
2000-11-11Don't have separate versions of "ddp_hops()" and "ddp_len()" onGuy Harris1-11/+11
big-endian and little-endian platforms; just put "ddp.hops_len" in host byte order and have one version. (This removes one usage of BIG_ENDIAN and LITTLE_ENDIAN from Ethereal - our redefining of them causes warnings on FreeBSD 3.4, so I'd like not to export them to all the dissectors if possible - and also fixes "ddp_hops()" to work correctly on little-endian machines, as the little-endian version wasn't byte-swapping its argument.) svn path=/trunk/; revision=2609
2000-08-13Add the "Edit:Protocols..." feature which currently only implementsLaurent Deniel1-1/+7
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 Harris1-17/+17
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
2000-05-31Add routines for adding items to a protocol tree that take arguments ofGuy Harris1-29/+29
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
2000-05-30Give the IPX dissector dissector hash tables for the IPX type and socketGuy Harris1-2/+1
number, and have the protocols encapsulated inside IPX register themselves with that table. svn path=/trunk/; revision=2028
2000-05-28Give the Appletalk DDP dissector a dissector hash table, and have theGuy Harris1-28/+13
protocols encapsulated inside DDP register themselves with that table. Pull the EIGRP dissector into its own file, as suggested by Paul Ionescu; it's not an IP-specific protocol. svn path=/trunk/; revision=2022
2000-05-22EIGRP over Appletalk and EIGRP over IPX support, from Paul Ionescu.Guy Harris1-1/+7
svn path=/trunk/; revision=1994
2000-05-11Add tvbuff class.Gilbert Ramirez1-34/+34
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 a "ppp.protocol" dissector table for PPP, and have dissectorsGuy Harris1-1/+3
for protocols that run inside PPP register themselves with it using "dissector_add()". svn path=/trunk/; revision=1869
2000-04-13Change the sub-dissector handoff registration routines so that theGilbert Ramirez1-1/+8
sub-dissector table is not stored in the header_field_info struct, but in a separate namespace. Dissector tables are now registered by name and not by field ID. For example: udp_dissector_table = register_dissector_table("udp.port"); Because of this different namespace, dissector tables can have names that are not field names. This is useful for ethertype, since multiple fields are "ethertypes". packet-ethertype.c replaces ethertype.c (the name was changed so that it would be named in the same fashion as all the filenames passed to make-reg-dotc) Although it registers no protocol or field, it registers one dissector table: ethertype_dissector_table = register_dissector_table("ethertype"); All protocols that can be called because of an ethertype field now register that fact with dissector_add() calls. In this way, one dissector_table services all ethertype fields (hf_eth_type, hf_llc_type, hf_null_etype, hf_vlan_etype) Furthermore, the code allows for names of protocols to exist in the etype_vals, yet a dissector for that protocol doesn't exist. The name of the dissector is printed in COL_INFO. You're welcome, Richard. :-) svn path=/trunk/; revision=1848
