Use "fragment_add_check()" for IPv6 and CLNP reassembly. (Possibly an
issue for CLNP, with its 16-bit IDs, which could be duplicated in a
sufficiently large capture even if CLNP implementations don't
deliberately reuse IDs; less of an issue for IPv6, with its 32-bit IDs
and with its prohibition on reuse:
For every packet that is to be fragmented, the source node generates
an Identification value. The Identification must be different than
that of any other fragmented packet sent recently* with the same
Source Address and Destination Address. If a Routing header is
present, the Destination Address of concern is that of the final
destination.
* "recently" means within the maximum likely lifetime of a packet,
including transit time from source to destination and time spent
awaiting reassembly with other fragments of the same packet.
However, it is not required that a source node know the maximum
packet lifetime. Rather, it is assumed that the requirement can
be met by maintaining the Identification value as a simple, 32-
bit, "wrap-around" counter, incremented each time a packet must
be fragmented. It is an implementation choice whether to
maintain a single counter for the node or multiple counters,
e.g., one for each of the node's possible source addresses, or
one for each active (source address, destination address)
combination.
but perhaps we'll ultimately be able to get rid of the old
"fragment_add()" entirely and rename "fragment_add_check()" to
"fragment_add()").

Add the "Edit:Protocols..." feature which currently only implements
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.

Generalize the "ip_src" and "ip_dst" members of the "packet_info"
structure to "dl_src"/"dl_dst", "net_src"/"net_dst", and "src"/"dst"
addresses, where an address is an address type, an address length in
bytes, and a pointer to that many bytes.
"dl_{src,dst}" are the link-layer source/destination; "net_{src,dst}"
are the network-layer source/destination; "{src,dst}" are the
source/destination from the highest of those two layers that we have in
the packet.
Add a port type to "packet_info" as well, specifying whether it's a TCP
or UDP port.
Don't set the address and port columns in the dissector functions; just
set the address and port members of the "packet_info" structure. Set
the columns in "fill_in_columns()"; this means that if we're showing
COL_{DEF,RES,UNRES}_SRC" or "COL_{DEF,RES,UNRES}_DST", we only generate
the string from "src" or "dst", we don't generate a string for the
link-layer address and then overwrite it with a string for the
network-layer address (generating those strings costs CPU).
Add support for "conversations", where a "conversation" is (at present)
a source and destination address and a source and destination port. (In
the future, we may support "conversations" above the transport layer,
e.g. a TFTP conversation, where the first packet goes from the client to
the TFTP server port, but the reply comes back from a different port,
and all subsequent packets go between the client address/port and the
server address/new port, or an NFS conversation, which might include
lock manager, status monitor, and mount packets, as well as NFS
packets.)
Currently, all we support is a call that takes the source and
destination address/port pairs, looks them up in a hash table, and:
if nothing is found, creates a new entry in the hash table, and
assigns it a unique 32-bit conversation ID, and returns that
conversation ID;
if an entry is found, returns its conversation ID.
Use that in the SMB and AFS code to keep track of individual SMB or AFS
conversations. We need to match up requests and replies, as, for
certain replies, the operation code for the request to which it's a
reply doesn't show up in the reply - you have to find the request with a
matching transaction ID. Transaction IDs are per-conversation, so the
hash table for requests should include a conversation ID and transaction
ID as the key.
This allows SMB and AFS decoders to handle IPv4 or IPv6 addresses
transparently (and should allow the SMB decoder to handle NetBIOS atop
other protocols as well, if the source and destination address and port
values in the "packet_info" structure are set appropriately).
In the "Follow TCP Connection" code, check to make sure that the
addresses are IPv4 addressses; ultimately, that code should be changed
to use the conversation code instead, which will let it handle IPv6
transparently.

Change the sub-dissector handoff registration routines so that the
sub-dissector table is not stored in the header_field_info struct, but
in a separate namespace. Dissector tables are now registered by name
and not by field ID. For example:
udp_dissector_table = register_dissector_table("udp.port");
Because of this different namespace, dissector tables can have names
that are not field names. This is useful for ethertype, since multiple
fields are "ethertypes".
packet-ethertype.c replaces ethertype.c (the name was changed so that it
would be named in the same fashion as all the filenames passed to make-reg-dotc)
Although it registers no protocol or field, it registers one dissector table:
ethertype_dissector_table = register_dissector_table("ethertype");
All protocols that can be called because of an ethertype field now register
that fact with dissector_add() calls.
In this way, one dissector_table services all ethertype fields
(hf_eth_type, hf_llc_type, hf_null_etype, hf_vlan_etype)
Furthermore, the code allows for names of protocols to exist in the
etype_vals, yet a dissector for that protocol doesn't exist. The name
of the dissector is printed in COL_INFO. You're welcome, Richard. :-)
