2002-08-28Removed trailing whitespaces from .h and .c files using thejmayer1-10/+10
winapi_cleanup tool written by Patrik Stridvall for the wine project. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@6117 f5534014-38df-0310-8fa8-9805f1628bb7
2002-08-02Replace the types from sys/types.h and netinet/in.h by their glib.hjmayer1-8/+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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@5932 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"guy1-5/+5
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
2001-12-08Attach a descriptive name field type and base to dissector tables; thatguy1-2/+3
specifies how the selector values used as keys in those tables are to be displayed, and the title to use when displaying the table. Use that information in the code to display the initial and current entries of various dissector tables. Have the dissector for BACnet APDUs register itself by name, and have the BACnet NPDU dissector call it iff the BAC_CONTROL_NET bit isn't set, rather than doing it with a dissector table. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@4358 f5534014-38df-0310-8fa8-9805f1628bb7

2001-01-22Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="guy1-5/+1
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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2928 f5534014-38df-0310-8fa8-9805f1628bb7
2001-01-13Make GRE use a dissector table for its protocol types, and registerguy1-52/+24
dissectors for protcools that can be encapsulated inside GRE in that table. Fix a bug in the handling of WCCPv2 IP encapsulation (it was constructing the next tvbuff before, rather than after, advancing the offset past the redirection header). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2893 f5534014-38df-0310-8fa8-9805f1628bb7

2001-01-09Add an additional "protocol index" argument to "{old_}dissector_add()",guy1-2/+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....) 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/+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. 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 columnguy1-2/+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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2670 f5534014-38df-0310-8fa8-9805f1628bb7
2000-11-19Have the Etherenet and PPP dissectors register themselves, and haveguy1-5/+5
other dissectors call them through handles. Do the same for the "PPP payload" dissector, after tvbuffifying it. Tvbuffify the PPPoE dissector. Do the last little bit of tvbuffifying the L2TP dissector (it takes old-style arguments and immediately generates a tvbuff out of them; make it take new-style arguments). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2664 f5534014-38df-0310-8fa8-9805f1628bb7
2000-11-18Tvbuffify the IP, ICMP, TCP, UDP, OSI CLNP, OSI COTP, OSI CLTP, and OSIguy1-3/+10
ESIS dissectors. Register the IP dissector and have dissectors that call it directly (rather than through a port table) call it through a handle. Add a routine "tvb_set_reported_length()" which a dissector can use if it was handed a tvbuff that contains more data than is actually in its part of the packet - for example, handing a padded Ethernet frame to IP; the routine sets the reported length of the tvbuff (and also adjusts the actual length, as appropriate). Then use it in IP. Given that, "ethertype()" can determine how much of the Ethernet frame was actually part of an IP datagram (and can do the same for other protocols under Ethernet that use "tvb_set_reported_length()"; have it return the actual length, and have "dissect_eth()" and "dissect_vlan()" use that to mark trailer data in Ethernet II frames as well as in 802.3 frames. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2658 f5534014-38df-0310-8fa8-9805f1628bb7
2000-11-16Tvbuffify the STP dissector, have it register itself and have the LLCguy1-2/+2
dissector call it through a handle, and make it static. Give "dissect_data()" an "offset" argument, so dissectors can use it to dissect part of the packet without having to cook up a new tvbuff. Go back to using "dissect_data()" to dissect the data in an IPP request. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2651 f5534014-38df-0310-8fa8-9805f1628bb7
2000-08-13Add the "Edit:Protocols..." feature which currently only implementsdeniel1-1/+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. 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)guy1-4/+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/+2
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
2000-05-31Add routines for adding items to a protocol tree that take arguments ofguy1-2/+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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@2031 f5534014-38df-0310-8fa8-9805f1628bb7
2000-05-25Convert dissect_ppp() and friends to use tvbuffs.gram1-2/+4
(the ip_tcp_options stuff is still non-tvbuff until I convert ip and tcp). Add preliminary fix for Linux ISDN ippp devices (similar watch was posted to ethereal-users, but did not use tvbuffs). Change packet-raw.c to call capture_ppp()/dissect_ppp() in the case where the frame starts with FF:03. We had been calling capture_ip()/dissect_ip() at byte offset 4, but I think this is for historical reasons of packet-raw.c and packet-ip.c existing before packet-ppp.c. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1998 f5534014-38df-0310-8fa8-9805f1628bb7

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.

1999-12-09Add RFC 1702 GRE-over-IPv4.guy1-12/+27
The routing information in a GRE packet is a list of items; dissect all of them (partially - we don't actually dissect the routing data). git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1252 f5534014-38df-0310-8fa8-9805f1628bb7

1999-11-16Replace the ETT_ "enum" members, declared in "packet.h", withguy1-4/+11
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. git-svn-id: http://anonsvn.wireshark.org/wireshark/trunk@1043 f5534014-38df-0310-8fa8-9805f1628bb7
