2004-03-06Add routines to process IPv{4,6}-address-and-prefix-length pairs,Guy Harris1-25/+14
masking out the appropriate bits in the address. Use them in the BGP and EIGRP dissectors. svn path=/trunk/; revision=10327
2004-03-06Put in the URL of a page that discusses EIGRP packets.Guy Harris1-13/+45
Handle the prefix length and address similarly to the way that the BGP dissector does, so that we mask out all the bits that the prefix length tells us to, rather than just masking out entire bytes. Check the prefix length so that we don't overflow the buffer for prefix lengths > 32 - thanks to Stefan Esser for catching that one - and so that we're not confused by a prefix length of 0. svn path=/trunk/; revision=10324
2002-08-28Removed trailing whitespaces from .h and .c files using theJörg Mayer1-34/+34
winapi_cleanup tool written by Patrik Stridvall for the wine project. svn path=/trunk/; revision=6117
2002-08-02Replace the types from sys/types.h and netinet/in.h by their glib.hJörg Mayer1-9/+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. svn path=/trunk/; revision=5932
2002-05-02From Joerg Mayer: get rid of unused arguments.Guy Harris1-29/+40
Fix the spelling of "Reserved". Use "proto_item_append_text()" when dissecting EIGRP TLVs, so they don't have to put in name of the TLV into the top-level item for the TLV, they can just append to the name that's already there. svn path=/trunk/; revision=5354
2002-02-01Provide tvb_ensure_length_remaining(), which is likeGilbert Ramirez1-2/+2
tvb_length_remaining() except that it throws BoundsError if 'offset' is out-of-bounds. Allow a length argument of -1 for FT_STRING and FT_BYTES fields in proto_tree_add_item(). Change some dissectors to either use -1 for the length argument in calls to proto_tree_add_item(), or call tvb_ensure_length_remaining() instead of tvb_length_remaining(), or to check the return-value of tvb_length_remaining(). Changes to more dissectors are necessary, but will follow later. svn path=/trunk/; revision=4656
2002-01-24Replace a bunch of "tvb_length()" and "tvb_length_remaining()" calls inGuy Harris1-4/+4
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 Harris1-4/+4
"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
2001-12-10Move the pointer to the "column_info" structure in the "frame_data"Guy Harris1-7/+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. svn path=/trunk/; revision=4370
2001-12-03Make "dissector_add()", "dissector_delete()", and "dissector_change()"Guy Harris1-5/+7
take a dissector handle as an argument, rather than a pointer to a dissector function and a protocol ID. Associate dissector handles with dissector table entries. svn path=/trunk/; revision=4308
2001-06-18From Joerg Mayer: explicitly fill in all members of aGuy Harris1-4/+4
"header_field_info" structure, including the ones that are later set by the routines to register fields. svn path=/trunk/; revision=3561
2001-05-03IPX SAP over IPX EIGRP support, and IP EIGRP authentication updates,Guy Harris1-14/+32
from Paul Ionescu. svn path=/trunk/; revision=3398
2001-04-23Move the declarations of IP protocol numbers to "ipproto.h" fromGuy Harris1-3/+3
"packet-ip.h". Fix Gerald's address in some files while we're at it. svn path=/trunk/; revision=3366
2001-04-20Put the top-level item for a TLV into the protocol tree with a textGuy Harris1-9/+3
value, so that if we throw an exception while processing that TLV before setting it in the dissector for that particular TLV we at least have something in the tree. svn path=/trunk/; revision=3344
2001-03-22Move appletalk- and sna-related address routines out of the dissectorsGilbert Ramirez1-2/+2
and into epan. svn path=/trunk/; revision=3160
2001-01-22Remove more "CHECK_DISPLAY_AS_DATA()" calls and "pinfo->current_proto ="Guy Harris1-12/+11
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
2001-01-09Add an additional "protocol index" argument to "{old_}dissector_add()",Guy Harris1-4/+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....) 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
2000-11-19For each column, have both a buffer into which strings for that columnGuy Harris1-2/+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. svn path=/trunk/; revision=2670
2000-11-14Add a ; to the empty default case in a switch statement. ANSI C saysGilbert Ramirez1-1/+3
you need some statement there, and a semicolon serves as a statement. Put a comment in there too, emphasizing the fact that the default case was meant to be empty. svn path=/trunk/; revision=2645
2000-11-09New EIGRP dissector, from Paul Ionescu.Guy Harris1-54/+384
svn path=/trunk/; revision=2585
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
2000-08-07Allow either old-style (pre-tvbuff) or new-style (tvbuffified)Guy Harris1-4/+4
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
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
2000-05-30Give the IPX dissector dissector hash tables for the IPX type and socketGuy Harris1-3/+4
number, and have the protocols encapsulated inside IPX register themselves with that table. svn path=/trunk/; revision=2028
2000-05-30#include netinet/in.h (for ntohs() macro), if available.Gilbert Ramirez1-1/+5
svn path=/trunk/; revision=2027
2000-05-28Give the Appletalk DDP dissector a dissector hash table, and have theGuy Harris1-0/+132
protocols encapsulated inside DDP register themselves with that table. Pull the EIGRP dissector into its own file, as suggested by Paul Ionescu; it's not an IP-specific protocol. svn path=/trunk/; revision=2022
