2002-04-17In a ChangeHosts request, display 4-byte Internet addresses as IPv4guy1-28/+21
addresses. When showing a list of keysyms, build the text representation of the item for the list by appending keysyms to the text of the item as dissected; this fixes a bug in the display of those keysums, and means that we don't build a text string with the keysyms if we're not generating the text representation. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@5179 f5534014-38df-0310-8fa8-9805f1628bb7

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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4605 f5534014-38df-0310-8fa8-9805f1628bb7
2002-01-21Include files from the "epan" directory and subdirectories thereof withguy1-2/+2
"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/"). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4586 f5534014-38df-0310-8fa8-9805f1628bb7
2001-12-10Move the pointer to the "column_info" structure in the "frame_data"guy1-7/+7
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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4370 f5534014-38df-0310-8fa8-9805f1628bb7

2001-04-20Check in the file used to define fields for the X11 dissector, and theguy1-3/+3
Perl script that generates them, so that if we have to change those fields we can do so more conveniently. Remove the generated header files from CVS, and arrange that we generate them when we do a build. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@3341 f5534014-38df-0310-8fa8-9805f1628bb7
2001-02-01Create a more modular type system for the FT_* types. Put themgram1-11/+11
into epan/ftypes. Re-write display filter routines using Lemon parser instead of yacc. Besides using a different tool, the new grammar is much simpler, while the display filter engine itself is more powerful and more easily extended. Add dftest executable, to test display filter "bytecode" generation. Add option to "configure" to build dftest or randpkt, both of which are not built by default. Implement Ed Warnicke's ideas about dranges in the new display filter and ftype code. Remove type FT_TEXT_ONLY in favor of FT_NONE, and have protocols registered as FT_PROTOCOL. Thus, FT_NONE is used only for simple labels in the proto tree, while FT_PROTOCOL is used for protocols. This was necessary for being able to make byte slices (ranges) out of protocols, like "frame[0:3]" Win32 Makefile.nmake's will be added tonight. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2967 f5534014-38df-0310-8fa8-9805f1628bb7
2001-01-22Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="guy1-13/+4
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. Don't use col_add_fstr(..., "%s", string); Use col_add_str(..., string); as it does the same thing, but doesn't drag all the heavy *printf machinery in. Fix the DDTP dissector to set the Info column regardless of whether we're building a protocol tree or not, and to set it to "Encrypted payload" if the payload is encrypted. Also fix a typo in a field name. Register the FTP data dissector as being associated with the FTP data protocol, not the FTP protocol (the removed "CHECK_DISPLAY_AS_DATA()" call checked "proto_ftp_data", and the removed "pinfo->current_proto =" line set it to "FTP-DATA", so it should be associated with "proto_ftp_data"). Make the H1 dissector check whether the frame has at least 2 bytes in it before checking the first two bytes; heuristic dissectors must not throw exceptions until they've accepted the packet as one of theirs. Use "tvb_format_text()" rather than "tvb_get_ptr()" and "format_text()" in some dissectors where the result of "tvb_get_ptr()" is used only in the "format_text()" call. In the Quake dissector, don't check whether there are at least 4 bytes in the packet - if we return, the packet won't be dissected at all (it's not as if some other dissector will get to handle it), and, if we don't return, we'll throw an exception if there aren't at least 4 bytes in the packet, so the packet will be marked as short or malformed, as appropriate. In the RIPng dissector, associate the table of strings for the command field with the command field, so that the dissector doesn't have to format the string for the protocol tree entry itself, and so that the filter construction dialog box can let you select "Request" or "Response" from a list rather than requiring you to know the values for "Request" and "Response". Make "dissect_rpc()" static, as it's called only through a heuristic dissector list. Use "col_set_str()" to set the COL_PROTOCOL column for RPC protocols; the string used is from a table provided by the dissector, and is a string constant. Don't format the Info column for WSP into a buffer and then format that buffer into the column with "%s" - "col_add_fstr()" can do the formatting for you, without having to allocate your own buffer (or run through the *printf machinery twice). Don't fetch fields from the WTP packet until you're ready to use them, so that you don't throw an exception before you even set the Protocol column or clear the Info column. Use "pinfo->destport", not "pi.destport", in the Zebra dissector when checking whether the packet is a request or reply, and do the check by comparing with "pinfo->match_port" rather than TCP_PORT_ZEBRA (so that if the dissector is ever registered on another port, it still correctly determines whether the packet is a request or reply - the Network Monitor HTTP dissector has port 80 wired into its brain, which is a bit irritating if you're trying to get it to dissect HTTP proxy traffic on port 3128 or proxy administration UI traffic on port 3132). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2931 f5534014-38df-0310-8fa8-9805f1628bb7
2001-01-09Add an additional "protocol index" argument to "{old_}dissector_add()",guy1-4/+4
"{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....) git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2849 f5534014-38df-0310-8fa8-9805f1628bb7
2001-01-03Have "proto_register_protocol()" build a list of data structures forguy1-2/+2
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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2810 f5534014-38df-0310-8fa8-9805f1628bb7
2000-11-19For each column, have both a buffer into which strings for that columnguy1-5/+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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2670 f5534014-38df-0310-8fa8-9805f1628bb7

2000-08-13Add the "Edit:Protocols..." feature which currently only implementsdeniel1-1/+4
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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2267 f5534014-38df-0310-8fa8-9805f1628bb7
2000-08-07Allow either old-style (pre-tvbuff) or new-style (tvbuffified)guy1-6/+6
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()". git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2218 f5534014-38df-0310-8fa8-9805f1628bb7

2000-06-15Convert IPX-and-friend dissectors in packet-ipx.c to usegram1-2/+3
tvbuffs. In doing so, I realied that my recommendation for using tvb_new_subset(pi.compat_top_tvb, -1, -1) was incorrect, because some dissectors (ethernet!) change pi.len and pi.cap_len. So, I have to take those two variables into account instead of using -1 and -1. So, I provide a macro called tvb_create_from_top(offset), where offset is the name of your offset variable. It is a wrapper around tvb_new_subset(). I converted the lines that followed my suggestion to use tvb_create_from_top(). In proto.c I added proto_tree_add_debug_text(proto_tree*, const char*, ...) It's much like proto_tree_add_text(), except that it takes no offset or length; it's soley for temporarily putting debug text into the proto_tree while debugging a dissector. In making sure that its use is temporary, the funciton also prints the debug string to stdout to remind the programmer that the debug code needs to be removed before shipping the code. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2068 f5534014-38df-0310-8fa8-9805f1628bb7

It's defined (at least in the X11R6 on my FreeBSD 3.4 system) as "((unsigned long)~0L)", which presumably means "set all the bits" - which means "set all 32 bits" in the "value_string" table where it appears, as the value member of an entry in such a table is a "guint32", so just use 0xFFFFFFFF. Get rid of other unneeded #includes as well. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2061 f5534014-38df-0310-8fa8-9805f1628bb7
2000-06-12Partial tvbuffification of the X11 dissector; we construct a tvbuff fromguy1-284/+320
the top-level "compatibility" tvbuff, so that we don't blow up if we get short frames *or* misinterpret data due to, for example, trying to treat the initial client->server message in a connection as an X11 request, or interpreting the middle of a multi-frame request (e.g., a big PutImage) as if it contained requests. (I have a capture file on which the non-tvbuffified code crashed.) Attempt to dissect requests until we reach the end of the frame, even if that would take us past the end of the captured data in the frame before we reach the end of the frame; the tvbuff code will throw an exception if we go past the end of the captured data, which means it'll put a "Short frame" indication into the protocol tree, which is what we want (the frame *is* short, because the capture length was too short). Define functions taking no arguments with a "(void)" argument list, so that the compiler knows that they must not be passed any arguments. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2059 f5534014-38df-0310-8fa8-9805f1628bb7
