- 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.

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.

"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/").

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.

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".

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.

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.

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.)

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.

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.

"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.

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.
