2004-07-18Move dissectors to epan/dissectors directory.Gilbert Ramirez1-362/+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 Mayer1-18/+18
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
2002-02-10Put ARP hardware addresses that are MAC addresses into the protocol treeGuy Harris1-34/+100
as FT_ETHER fields, not FT_BYTES fields. Only label Appletalk protocol addresses as "{Source,Target} ID"; label the others as "{Source,Target} protocol address", and have different fields for Appletalk and other protocol addresses. Don't put addresses into the protocol tree if they're zero-length. svn path=/trunk/; revision=4717
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
2001-12-10Move the pointer to the "column_info" structure in the "frame_data"Guy Harris1-10/+10
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/+10
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 Harris1-10/+10
"header_field_info" structure, including the ones that are later set by the routines to register fields. svn path=/trunk/; revision=3561
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
2001-03-13Make tvb_get_ptr() return 'const guint8*', and clean up all theGilbert Ramirez1-4/+4
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
2001-01-22Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="Guy Harris1-7/+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. svn path=/trunk/; revision=2928
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
2000-11-19For 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
2000-11-13Move "bytes_to_str()" to "strutil.c" from "packet.c" - it's just aGuy Harris1-1/+2
string formatter, like "format_text()", and, as "tvbuff.c" now calls it (*vide infra*), we don't want to have to make "tvbuff.c" drag "packet.h" in just to declare "bytes_to_str()". It's now declared in "strutil.h", so include it in modules that use "bytes_to_str()" and weren't already including it. Add a "tvb_bytes_to_str()" wrapper that calls "tvb_get_ptr()" to get a pointer to a chunk of N bytes at a given offset in a tvbuff and then hands that chunk to "bytes_to_str()". Convert the code that was doing that to use "tvb_bytes_to_str()" instead (which caught what I suspect is a bug in the Q.2931 dissector, where it was handing an offset of 0 to "tvb_get_ptr()" - a cut-and-pasteo, I think). Tvbuffify the ARP dissector. svn path=/trunk/; revision=2634
2000-11-13Tvbuffify the AppleTalk ARP dissector.Guy Harris1-46/+45
svn path=/trunk/; revision=2628
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 Harris1-4/+4
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 Harris1-6/+6
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 Ramirez1-12/+12
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
2000-04-13Change the sub-dissector handoff registration routines so that theGilbert Ramirez1-1/+7
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
2000-03-12Break proto_tree_add_item_format() into multiple functions:Gilbert Ramirez1-9/+9
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

1999-11-16Replace the ETT_ "enum" members, declared in "packet.h", withGuy Harris1-2/+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
1999-11-04Decode the hardware and protocol types.Guy Harris1-85/+127
Define the hardware type, protocol type, and opcode values fields as enums. Dissect the addresses the same way the ARP dissector does, so that we don't completely give up if the hardware addresses aren't 6-byte Ethernet/Token Ring addresses or the protocol addresses aren't 4-byte Appletalk IDs. svn path=/trunk/; revision=972
1999-10-16Replace proto_tree_add_item_format by proto_tree_add_item.Laurent Deniel1-26/+26
svn path=/trunk/; revision=850
1999-10-12New proto_tree header_field_info stuff. Header_field_infos now containGilbert Ramirez1-10/+27
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
1999-10-03Oops, forgot to check truncated header.Laurent Deniel1-1/+6
Please, please in new dissector routines, check for truncated packets, especially when string operations or loop on bytes are used (to avoid display of erroneous data and infinite loop or segmentation violation) ! svn path=/trunk/; revision=763

1999-07-29Made the protocol (but not the fields) use the new proto_tree routine,Gilbert Ramirez1-2/+16

1999-03-23Removed all references to gtk objects from packet*.[ch] files. They nowGilbert Ramirez1-25/+19
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

1998-11-12A lengthy patch to add the wiretap library. Wiretap is not used by defaultGilbert Ramirez1-1/+0
because it is still in its infancy, but it can be compiled in optionally. The library exists in its own subdirectory ethereal/wiretap. This patch also edits all the packet-*.c files to remove the #include <pcap.h> line which is unnecessary in these files.
