2002-08-28Removed trailing whitespaces from .h and .c files using theJörg Mayer1-61/+61
winapi_cleanup tool written by Patrik Stridvall for the wine project. svn path=/trunk/; revision=6117
2002-08-19When processing "i" and "a" tags, check only whether we've seen an "m"Guy Harris1-22/+9
tag or not - if we haven't, "i" is "session info" and "a" is "session attribute", and if we have, "i" is "media title" and "a" is "media attribute". svn path=/trunk/; revision=6018
2002-08-02Replace the types from sys/types.h and netinet/in.h by their glib.hJörg Mayer1-8/+4
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
2002-04-14From Joerg Mayer: get rid of some unused variables and arguments.Guy Harris1-76/+34
Use "tvb_get_ntohs()" to fetch the checksum from a VJ compressed packet, rather than doing the ntoh by hand. svn path=/trunk/; revision=5163
2002-02-02Sigh. Strings in SDP may have tabs in them, so we need to useGuy Harris1-3/+7
"format_text()" to display them, so that the tabs show up as "\t". (We eventually need to use that when displaying string fields - and arrange that it properly handle the character set of the font being used for display, in Ethereal, and the character set of the user's locale, in Tethereal). svn path=/trunk/; revision=4685
2002-02-02The argument to "proto_tree_add_string()" must be a null-terminatedGuy Harris1-5/+9
string; make it so. svn path=/trunk/; revision=4683
2002-02-02Use "proto_tree_add_item()" to add string items.Guy Harris1-122/+80
Use -1, rather than the result of "tvb_length_remaining()", to handle the last string item in a tvbuff. svn path=/trunk/; revision=4670
2002-01-24Replace a bunch of "tvb_length()" and "tvb_length_remaining()" calls inGuy Harris1-3/+2
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
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
2001-12-15Added handling for all of the subfields of SDP.Ed Warnicke1-8/+757

2001-12-15Fix an incorrect entry for the "Media Attribute" item.Guy Harris1-5/+5
Clean up the entry for the protocol version item. svn path=/trunk/; revision=4397
2001-12-13Added hf fields for all of the top level field types.Ed Warnicke1-65/+169
svn path=/trunk/; revision=4395
2001-12-10Move the pointer to the "column_info" structure in the "frame_data"Guy Harris1-9/+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
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
2000-11-19Fixes, from Heikki Vatiainen, to bugs introduced by the tvbuffificationGuy Harris1-1/+2
of the SAP and SDP dissectors. svn path=/trunk/; revision=2676
2000-11-15Add a mechanism by which a dissector can be registered by name, anotherGuy Harris1-2/+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
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
2000-11-13Don't overwrite the "Info" column in the SDP dissector, either - appendGuy Harris1-2/+16
to it, so as not to stomp on what the protocol that's using SDP put there. svn path=/trunk/; revision=2625
2000-11-12As RFC 2327 says, "SDP is purely a format for session description - itGuy Harris1-2/+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
2000-11-10Tvbuffify the SAP and SDP dissectors.Guy Harris1-29/+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
2000-11-09Support for embedded newlines in SDP fields, from Robert Tsai.Guy Harris1-3/+4
svn path=/trunk/; revision=2584
2000-09-11Move format_text(), get_token_len(), and fine_line_end(), into strutil.cGilbert Ramirez1-1/+2
This keeps tvbuff.c generic; it doesn't have to pull in packet.h and all of it's included files. svn path=/trunk/; revision=2409
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 Harris1-2/+2
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 Ramirez1-5/+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

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
1999-07-29Made the protocol (but not the fields) use the new proto_tree routine,Gilbert Ramirez1-3/+16
