- unify the IS-IS CLV space IS-IS uses a unified CLV space across all Level and PDU Types there is no need to define PDU- and Level- Specific CLV Types; - clean up Authentication CLV TLV #10 is the official supported TLV for carrying authentication information- todays code displays TLV #10 as non-standard which is wrong; also the notion of "Domain" "Authentication" and "Link" password has disappeared from contemporary routing SW; - add IP Authentication CLV dissector this CLV is depreciated - however it is using different semantics than TLV #10 so we need a dedicated dissector; - add Checksum CLV dissector add support for RFC 3358 Checksum CLVs majority of code re-used from the LSP checksum verification dissector. svn path=/trunk/; revision=9204

2003-05-28From Laurent Rabret: show checksum status in a sub-item for the checksumGuy Harris1-35/+42
field, and add a "bad checksum" filterable field. svn path=/trunk/; revision=7757
2003-05-15From Laurent Rabret:Guy Harris1-12/+46
fix a bug where bad IPv4 and IPv6 prefix lengths could cause a buffer overflow; check the checksum in LSP packets. svn path=/trunk/; revision=7675

svn path=/trunk/; revision=7389
2003-03-31The "attached_string" doesn't apply to the attachments, so call itGuy Harris1-4/+4
"supported_string", instead, as it is used to indicate whether partition repair is supported. Fix a typo. svn path=/trunk/; revision=7384
2003-03-30From Hannes Gredler:Guy Harris1-40/+163
- TLV 135 cleanup and support for subTLVs - a common IP Reach subTLV dissector which dissects subTLV 1 & 2 [32 & 64 Bit Admin Tags as per draft-ietf-isis-admin-tags-01.txt] - rework IPv6-related TLVs. svn path=/trunk/; revision=7381
2003-03-27From Laurent Rabret: fix bugs in ISIS LSP analyses, addi type blockGuy Harris1-40/+77
filters and display the type block byte in a more standard way (bit fields). svn path=/trunk/; revision=7378
2002-09-02From Hannes Gredler:Guy Harris1-32/+8
open up a new subtree for dissecting the lsp-entry TLV; remove the isis_lsp_decode_lsp_id() routine, as the same functionality is better served using print_system_id(); fix a small bug in print_system_id(). svn path=/trunk/; revision=6169
2002-08-29From Hannes Gredler: make the IS-IS dissector more verbose in the INFOGuy Harris1-3/+12
field - specifically for IIHs the System-ID of the Hello; LSPs the LSP-ID, Sequence #, Lifetime; CSNPs the LAN-ID, Start LSP-ID, End LSP-ID. and change the display of some IDs. Clean up white space. svn path=/trunk/; revision=6128
2002-08-28Removed trailing whitespaces from .h and .c files using theJörg Mayer1-121/+121
winapi_cleanup tool written by Patrik Stridvall for the wine project. svn path=/trunk/; revision=6117
2002-08-04net/inet.h should not be needed by a dissector.Jörg Mayer1-5/+1
svn path=/trunk/; revision=5950
2002-08-02Replace the types from sys/types.h and netinet/in.h by their glib.hJörg Mayer1-5/+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
2002-05-07From Chenjiang Hu: use the correct offset when fetching unreservedGuy Harris1-2/+2
bandwidth values. svn path=/trunk/; revision=5414
2002-05-02From Joerg Mayer: mark unused arguments as such.Guy Harris1-16/+16
Add a check in "dissect_hello_restart_clv()" that the length of the TLV is correct. Use "val_to_str()" to get the name of the adjacency state in "dissect_hello_ptp_adj_clv()". svn path=/trunk/; revision=5357
2002-04-24Use "tvb_get_ntohieee_float()" to fetch floating-point numbers.Guy Harris1-10/+4
svn path=/trunk/; revision=5242
2002-04-07Get rid of the unused hf_ value "hf_isis_hello_clv_restart".Guy Harris1-1/+5
Use the "tree_id" argument to "isis_dissect_mt_clv()" for the 2-byte MT IDs, and arrange that the two hf_ values passed as that argument actually be defined for protocol fields. Fix the loop in "isis_dissect_mt_clv()" so that it actually catches an odd byte at the end (i.e., loop until there is data at all, not until there is 1 or fewer bytes), and put that odd byte, if it exists, into the tree as a 1-byte text item, not a 2-byte text item. svn path=/trunk/; revision=5113
2002-04-07Get rid of unused "pinfo" arguments.Guy Harris1-157/+95
svn path=/trunk/; revision=5112
2002-03-23From Heikki Vatiainen: fix the test for IS-IS virtual links.Guy Harris1-2/+2
svn path=/trunk/; revision=5010
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
2002-01-20Allow a length of -1 to be specified when adding FT_NONE and FT_PROTOCOLGuy Harris1-7/+7
items to the protocol tree; it's interpreted as "the rest of the data in the tvbuff". This can be used if 1) the item covers the entire packet or the remaining payload in the packet or 2) the item's length won't be known until it's dissected, and will be then set with "proto_item_set_len()" - if an exception is thrown in the dissection, it means the item ran *past* the end of the tvbuff, so saying it runs to the end of the tvbuff is reasonable. Convert a number of "proto_tree_add_XXX()" calls using "tvb_length_remaining()", values derived from the result of "tvb_length()", or 0 (in the case of items whose length is unknown) to use -1 instead (using 0 means that if an exception is thrown, selecting the item highlights nothing; using -1 means it highlights all the data for that item that's available). In some places where "tvb_length()" or "tvb_length_remaining()" was used to determine how large a packet is, use "tvb_reported_length()" or "tvb_reported_length_remaining()", instead - the first two calls indicate how much captured data was in the packet, the latter two calls indicate how large the packet actually was (and the fact that using the latter could cause BoundsError exceptions to be thrown is a feature - if such an exception is thrown, the frame really *was* short, and it should be tagged as such). Replace some "proto_tree_add_XXX()" calls with equivalent "proto_tree_add_item()" calls. Fix some indentation. svn path=/trunk/; revision=4578
2001-12-26From Hannes Gredler:Guy Harris1-2/+2
System IDs in IS neighbor CLVs in Hello PDUs are assumed to be MAC addresses, so use "get_ether_name()" on them to try to resolve them to host names. Properly label IS type values of ISIS_LSP_TYPE_LEVEL_2 as being "Level 1 and Level 2 IS". svn path=/trunk/; revision=4451
2001-12-20Put the Hello, LSP, and {C,P}SNP ISIS stuff into the ISIS protocol,Guy Harris1-32/+19
rather than having them each have their own protocol. svn path=/trunk/; revision=4432

svn path=/trunk/; revision=3626
2001-07-01Fix a typo, discovered whilst testing the tvbuffified ISIS dissectorGuy Harris1-2/+2
(the tvbuffified version is correct here; I'll check this in for reference purposes, even though I plan to check in the tvbuffified version later). svn path=/trunk/; revision=3625

hostname TLV support, from Hannes Gredler. svn path=/trunk/; revision=3271
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
2000-08-13Add 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
2000-06-19Make the "isis_hello.source_id" an FT_BYTES field rather than anGuy Harris1-83/+118
FT_ETHER field; the ISIS spec doesn't say it's necessarily a 6-byte Ethernet address (and, if it's FT_BYTES, you can test it in a filter much the same way you test an Ethernet address). Make "isis_hello.lan_id" an FT_BYTES field rather than an FT_STRING field - it's an array of bytes, not a character string. Don't require that "system ID" fields be 6 octets; use the size value from the ISIS PDU header. (This means that PDUs containing "system ID" fields can't be described as C structures; dissect them by stepping the offset instead.) svn path=/trunk/; revision=2080
2000-05-31Add routines for adding items to a protocol tree that take arguments ofGuy Harris1-6/+6
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 Ramirez1-16/+16
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
2000-04-15Ralf Schneider's changes to enhance to OSI CLNP, CLTP, and ISIS supportGuy Harris1-22/+12
and to add OSI ESIS support. svn path=/trunk/; revision=1865
2000-03-20Change dfilter_init() to check for empty-string abbreviations and forGilbert Ramirez1-2/+2
duplicate abbreviations. All mods to packet-*.c files are fixes to remove those cases. svn path=/trunk/; revision=1733
2000-01-24Fix a bunch of dissectors to use "pi.captured_len" rather thanGuy Harris1-4/+4
"fd->cap_len" for the frame length - or to use macros such as "BYTES_ARE_IN_FRAME()", "IS_DATA_IN_FRAME()", and "END_OF_FRAME", which use "pi.captured_len" - so that they correctly handle frames where the actual data length of the packet is less than the size of the raw frame, e.g. with encapsulations such as ISL. svn path=/trunk/; revision=1530
2000-01-15Merge in the final code to make Ethereal run on Win32, compiledGilbert Ramirez1-3/+7
with MSVC 6.0 and 'nmake', the make tool that comes with MSVC. It compiles, links, and runs. It doesn't run correctly. There's a problem when reading files. I'm getting short reads. I'm not linking in zlib or libsnmp because it first needs to be debugged. I changed the plugin code to use gmodule instead of libltdl, but the Unix build still links ethereal against libltdl. I'll fix that tonight; sorry about leaving it in such a sad state, but I wanted to check in this code before I left work on a Friday night. Ethereal still works, but the building is less than optimal. svn path=/trunk/; revision=1479
