* Add new routines:Guy Harris2003-06-121-8/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tvb_get_string() - takes a tvbuff, an offset, and a length as arguments, allocates a buffer big enough to hold a string with the specified number of bytes plus an added null terminator (i.e., length+1), copies the specified number of bytes from the tvbuff, at the specified offset, to that buffer and puts in a null terminator, and returns a pointer to that buffer (or throws an exception before allocating the buffer if that many bytes aren't available in the tvbuff); tvb_get_stringz() - takes a tvbuff, an offset, and a pointer to a "gint" as arguments, gets the size of the null-terminated string starting at the specified offset in the tvbuff (throwing an exception if the null terminator isn't found), allocates a buffer big enough to hold that string, copies the string to that buffer, and returns a pointer to that buffer and stores the length of the string (including the terminating null) in the variable pointed to by the "gint" pointer. Replace many pieces of code allocating a buffer and copying a string with calls to "tvb_get_string()" (for one thing, "tvb_get_string()" doesn't require you to remember that the argument to "tvb_get_nstringz0()" is the size of the buffer into which you're copying the string, which might be the length of the string to be copied *plus 1*). Don't use fixed-length buffers for null-terminated strings (even if the code that generates those packets has a #define to limit the length of the string). Use "tvb_get_stringz()", instead. In some cases where a value is fetched but is only used to pass an argument to a "proto_tree_add_XXX" routine, use "proto_tree_add_item()" instead. svn path=/trunk/; revision=7859

| | | | | | | | | | | | arguments to "proto_tree_add_text()", and to "proto_tree_add_XXX()" calls that add FT_NONE or FT_PROTO items to the protocol tree, with -1. Replace some calls to "tvb_length()" or "tvb_length_remaining()" with calls to "tvb_reported_length()" and "tvb_reported_length_remaining()", as those give the actual length of the data in the packet, not just the data that happened to be captured. svn path=/trunk/; revision=4605
* Include files from the "epan" directory and subdirectories thereof withGuy Harris2002-01-211-3/+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

* Move the pointer to the "column_info" structure in the "frame_data"Guy Harris2001-12-101-9/+6
| | | | | | | | | | | | | | | 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
* Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="Guy Harris2001-01-251-5/+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
* Add an additional "protocol index" argument to "{old_}dissector_add()",Guy Harris2001-01-091-2/+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
* Have "proto_register_protocol()" build a list of data structures forGuy Harris2001-01-031-2/+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

* Add a mechanism by which a dissector can be registered by name, anotherGuy Harris2000-11-151-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dissector can get a "handle" for that dissector by name and then call that dissector through the handle. This allows dissectors that can't be called through a port table or a heuristic table to be called from other dissectors without directly referring to the dissector function - dynamically-loaded modules, under Windows, cannot directly call functions in the main program, and non-plugin dissectors are in the main program and thus cannot be called from plugin dissectors unless either 1) a pointer to the dissector is put in the Big Transfer Vector or 2) some other mechanism for getting a pointer to the dissector is provided. This mechanism could also support registering old-style dissectors and calling them from new-style dissectors without the new-style dissector having to do the argument translation itself (I didn't add support for registering old-style dissectors because I'd prefer to have people tvbuffify their code if they have to register a dissector...). It could also, in the future, perhaps support disabling of protocols; setting "pinfo->current_proto"; inside "call_dissector()" - and inside "{old_}dissector_try_port()" and "{old_"dissector_try_heuristic()" - allowing a pile of stuff that currently has to be done in every dissector be done by common code. (I have some ideas about how to do this, by having "proto_register_protocol()" take an abbreviation - of the sort that would be put in, for example, "pinfo->current_proto" - as an argument; having the calls to register dissectors take an index returned by "proto_register_protocol()" as an argument. The abbreviation could be used elsewhere as well, e.g. in the "Decoding" tab of the "Edit->Protocols" dialog box, and in a GUI for constructing protocol filters. Watch this space.) Make "dissect_sdp()" the first client of this mechanism; it's now static to "packet-sdp.c", and all dissectors that call it - including the MGCP plugin - now call it through a dissector handle fetched by "find_dissector()". (Next step - see if Ethereal can now compile on Windows as a result of this.) svn path=/trunk/; revision=2647

* Don't overwrite the "Info" column in the SDP dissector, either - appendGuy Harris2000-11-131-2/+16

* As RFC 2327 says, "SDP is purely a format for session description - itGuy Harris2000-11-121-2/+2
| | | | | | | | | | | | | | | | | | | does not incorporate a transport protocol, and is intended to use different transport protocols as appropriate including the Session Announcement Protocol [4], Session Initiation Protocol [11], Real- Time Streaming Protocol [12], electronic mail using the MIME extensions, and the Hypertext Transport Protocol." As such, it shouldn't set the protocol column to SDP, as that means the protocol column won't indicate what the transport protocol was; instead, it should append "/SDP" to the protocol column - RTSP was, after calling "dissect_sdp()", setting the protocol column to "RTSP/SDP", and this change means that all protocols using SDP will have the protocol column set in that fashion, and that the RTSP dissector doesn't have to explicitly set the protocol column to cause that to happen. svn path=/trunk/; revision=2624
* Tvbuffify the SAP and SDP dissectors.Guy Harris2000-11-101-29/+38
| | | | | | | | | | | Add "tvb_find_line_end_unquoted()" for the benefit of the SDP dissector; get rid of "find_line_end_unquoted()" as nobody uses it any more. Add "tvb_pbrk_guint8()" for the benefit of "tvb_find_line_end_unquoted()"; it searches for any of a number of characters, unlike "tvb_find_guint8()" which searches for only one. svn path=/trunk/; revision=2595

* Add the "Edit:Protocols..." feature which currently only implementsLaurent Deniel2000-08-131-1/+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

| | | | | | | | | | | | | | | | | 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
* Add tvbuff class.Gilbert Ramirez2000-05-111-5/+5
| | | | | | | | | | | | | | | 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
