* Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="Guy Harris2001-01-221-24/+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
* Add an additional "protocol index" argument to "{old_}dissector_add()",Guy Harris2001-01-091-7/+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
* Have "proto_register_protocol()" build a list of data structures forGuy Harris2001-01-031-5/+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
* For each column, have both a buffer into which strings for that columnGuy Harris2000-11-191-5/+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

* Don't have separate versions of "ddp_hops()" and "ddp_len()" onGuy Harris2000-11-111-11/+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
* Add the "Edit:Protocols..." feature which currently only implementsLaurent Deniel2000-08-131-1/+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
* Allow either old-style (pre-tvbuff) or new-style (tvbuffified)Guy Harris2000-08-071-17/+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

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

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.

* Change the sub-dissector handoff registration routines so that theGilbert Ramirez2000-04-131-1/+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
* Break proto_tree_add_item_format() into multiple functions:Gilbert Ramirez2000-03-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Include <netinet/in.h> before including "global.h", so that if - asGuy Harris1999-11-041-5/+5
| | | | | | | | | appears to be the case on AIX 4.3.2 - it defines BIG_ENDIAN or LITTLE_ENDIAN differently from the way "global.h" defines them, and also defines BYTE_ORDER, we don't get a compiler warning - instead, "global.h" refrains from defining them (as BYTE_ORDER is defined). svn path=/trunk/; revision=970

Put the include back (I guess we could include "global.h" after including it, or move the byte-order stuff into a separate header file and include *that* after <netinet.h>, in order to squelch the complaints somebody saw compiling on AIX). svn path=/trunk/; revision=969

| | | | | | | | | | | | | | | | | | | | | 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.

Replace the "payload" field of a "packet_info" structure with "len" and "captured_len" fields, which contain the total packet length and total captured packet length (including all headers) at the current protocol layer (i.e., if a given layer has a length field, and that length field says its shorter than the length we got from the capture, reduce the "pi.len" and "pi.captured_len" values appropriately). Those fields can be used in the future if we add checks to make sure a field we're extracting from a packet doesn't go past the end of the packet, or past the captured part of the packet. Get rid of the additional payload argument to some dissection functions; use "pi.captured_len - offset" instead. Have the END_OF_FRAME macro use "pi.captured_len" rather than "fd->cap_len", so that "dissect the rest of the frame" becomes "dissect the rest of the packet", and doesn't dissect end-of-frame padding such as padding added to make an Ethernet frame 60 or more octets long. (We might want to rename it END_OF_PACKET; if we ever want to label the end-of-frame padding for the benefit of people curious what that extra gunk is, we could have a separate END_OF_FRAME macro that uses "fd->cap_len".) svn path=/trunk/; revision=506
