"packet-dcerpc-nt.c", and registers "dcerpc_smb_init()" as an
initialization routine. Take the ett_ registration out of the latter
routine, and also take out the "do this only once" stuff.
Get rid of the initialization routines for netlogon, samr, and spoolss;
they just call "dcerpc_smb_init()", which is now an initialization
routine of its own.
The policy hash initialization should be done before every capture, so
it should be done in an initialization routine, and should not do any
"do this only once" stuff. It should also be called only once before
every capture, rather than 3 times.
The ett_ initialization should, however, be done at the same time all
other ett_ initialization is done - at protocol registration time - so
it should be done in a "proto_register_" routine.
This fixes a bug I saw wherein
1) the tree for Unicode strings was open by default
and
2) if you closed one and then exited, Ethereal would crash.
The problem is that "proto_register_subtree_array()" doesn't expand the
array, it just bumps the number of registered ett_ values; the array is
allocated in "proto_init()". As such, if you register ett_ values with
"proto_register_subtree_array()" *after* "proto_init()" is called - and,
even for the first capture, initialization routines are called after
"proto_init()" is called - you will get ett_ numbers that go past the
number of elements in the array.
Move the declaration of "ett_nt_unicode_string" to "packet-dcerpc-nt.h",
as it's exported from "packet-dcerpc-nt.c".
Get rid of the declaration of "dcerpc_smb_init()" in

Always destroy the TCP segment key and address memory chunks in

but we should free them even if it's not enabled. Also, when we free

o Modifies the dcerpc handoff to subdissectors slightly. It
also needs to pass the data representation to the
subdissector. Also, if no subdissector is found, it puts a
"Stub data" entry in the tree.
o Adds optional TCP desegmentation to the dcerpc layer. Note
that dcerpc has it's own ability to fragment PDUs. This isn't
for dealing with that, but with the case of a single PDU being
broken over more than one TCP segment.
o Adds a little bit of dissection to packet-dcerpc-epm.c.
Mainly just proof of concept for the dcerpc handoff stuff.
(Writing this is how I realized the need for the drep.)
o Adds packet-dcerpc-ndr.c, which will contain NDR dissection

Also, support added for multiple PDUs per segment for DCERPC-over-TCP

Have the PGM dissector use the standard Ethereal mechanisms for

option types, the OPX bits, and packet types to strings. Use
"bytes_to_str()" to turn byte arrays into strings of hex digits. Pass
the packet type string to "dissect_pgmopts()" as an argument, rather
than making it a global. Don't use "proto_tree_add_XXX_format" routines
if you can possibly just use "proto_tree_add_XXX"; give various fields
the correct radix and type, and VALS() strings if necessary, to make
that happen (and to make filtering on them more pleasant). Put the
type, length, and total length of the options into the protocol tree as
separate fields. Don't have separate type, length, and OPX fields for
every type of option; one field will suffice. Don't format a string
with "sprintf()" and then pass that string to "col_add_fstr()" with a
format of "%s" and the string as an argument - "col_add_fstr()" can
format strings itself (that's what the "f" stands for). Don't byte-swap
and then un-byte-swap IPv4 address fields in the header, just leave them
network byte order to start with. Use the correct fields for
"proto_tree_add_XXX", rather than using the same field multiple times.
Quit early if an address family identifier isn't AFNUM_INET, as that
means the structure we use to dissect the header doesn't match the
actual header.

protocols, include the NLPID in the tvbuff you hand to
"dissector_try_port()" with that dissector table, and put the NLPID into
the protocol tree as an invisible item - the NLPID is considered part of
the PDU for those protocols, so you have to include it in the tvbuff,
and the dissector will put it into the protocol tree.
Also, make sure the top-level entry for the Frame Relay protocol

This, in turn, allows us to register the X.25 dissector, as there's now

version of libpcap; that's used on Linux for captures on the "any"
device (which captures from all interfaces simultaneously) and for
captures on devices whose link-layer type libpcap doesn't (yet) support
natively.
The spanning tree code, when checking for GV{M,R,...}P packets, must
first check whether the link-layer destination address is, in fact, an
Ethernet-style address; on Linux cooked captures, there *is* no
destination address, so it's of type AT_NONE, not AT_ETHER.

replace the existing checksummer with a modified version of the BSD
checksumming code. Add a flag to the "packet_info" structure to
indicate that a packet is the first fragment of a fragmented datagram,
so that the checksummers won't try to checksum those.
(It doesn't seem to add a lot of CPU overhead, so we don't introduce a
flag to disable it, yet. Further checks may be necessary to see whether
the overhead is just swamped by other overheads when scanning through a
capture dissecting all frames, or if it truly is negligible.)

dissector can get a "handle" for that dissector by name and then call
that dissector through the handle.
This allows dissectors that can't be called through a port table or a
heuristic table to be called from other dissectors without directly
referring to the dissector function - dynamically-loaded modules, under
Windows, cannot directly call functions in the main program, and
non-plugin dissectors are in the main program and thus cannot be called
from plugin dissectors unless either
1) a pointer to the dissector is put in the Big Transfer Vector
or
2) some other mechanism for getting a pointer to the dissector
is provided.
This mechanism could also support registering old-style dissectors and
calling them from new-style dissectors without the new-style dissector
having to do the argument translation itself (I didn't add support for
registering old-style dissectors because I'd prefer to have people
tvbuffify their code if they have to register a dissector...).
It could also, in the future, perhaps support
disabling of protocols;
setting "pinfo->current_proto";
inside "call_dissector()" - and inside "{old_}dissector_try_port()" and
"{old_"dissector_try_heuristic()" - allowing a pile of stuff that
currently has to be done in every dissector be done by common code.
(I have some ideas about how to do this, by
having "proto_register_protocol()" take an abbreviation - of the
sort that would be put in, for example, "pinfo->current_proto" -
as an argument;
having the calls to register dissectors take an index returned
by "proto_register_protocol()" as an argument.
The abbreviation could be used elsewhere as well, e.g. in the "Decoding"
tab of the "Edit->Protocols" dialog box, and in a GUI for constructing
protocol filters. Watch this space.)
Make "dissect_sdp()" the first client of this mechanism; it's now static
to "packet-sdp.c", and all dissectors that call it - including the MGCP
plugin - now call it through a dissector handle fetched by
"find_dissector()". (Next step - see if Ethereal can now compile on
Windows as a result of this.)

source *and* destination port and/or both the source *and* destination
address passed to "find_conversation()", because the packet for which
you're trying to find the conversation may be going in the opposite
direction to the packet for which the conversation was originally
created.
Create different hash tables for wildcarded conversations, to reduce the
number of "is this a wildcard?" tests done when doing hash lookups.
This is sufficient to allow the TFTP dissector to use conversations
rather than being special-cased in the UDP dissector, and may also be
sufficient to handle a similar problem with SMTP (request goes from
client IP X port Y to server IP Z's well-known port, reply comes back
from some other port on server Z to client IP X port Y), but further use
may reveal other changes that should be made.

"top-level" dissectors that libepan-users call, instead of dissect_packet().
The epan_dissect_t holds the tvbuff after dissection so that the tvbuff's
memory is not cleared until after the proto_tree is freed. (I might stuff
the proto_tree into the epan_dissect_t, too).
What remains of dissect_packet() in packet.c handles the tvbuff initialiation.
The real meat of dissect_packet() is now in dissect_frame(), in packet-frame.c
This means that "packet.c" is no longer a dissector, os it is no longer
passed to make-reg-dotc.
Once dissect_fddi() gets two wrapper functions (dissect_fddi_swapped()
and dissect_fddi_nonswapped()), the a dissector handoff routine could
be used instead of the switch statement in dissect_frame(). I'd register
a field like "wtap.encap"

Porting and Archive Centre site.
Warn in the very beginning of that file that libpcap may not work very
well without patches. Give patches to libpcap for:
vanilla LBL libpcap 0.4
vanilla tcpdump.org libpcap 0.5
libpcap 0.4 from the HP-UX Porting and Archive Centre (which is
the only version that includes configure-script changes to work
with HP's C compiler as well as GCC)
and put them in files separate from "README.hpux" (to make it easier for
users to apply the patches).
Make those versions of the patch give a slightly different error message
if libpcap fails to find the PPA for the device, to make it easier to
figure out if the user reporting a problem with HP-UX capture has a
patched version of libpcap or not (so that we know whether the problem
may just be that they're using an unmodified libpcap, or if they're
running a patched version and that patch needs more work, e.g. to look
at devices other than just "/dev/dlpi").
Give information on how to find "patch", warn that probably only the
HP-UX Porting and Archive Centre version will work with the HP C
compiler, warn that applying a version of the patch other than the one
for the particular version of libpcap you've downloaded will probably
not work, and warn that you need to download source to libpcap in order
to do any of this in the first place.
(The current libpcap CVS tree at tcpdump.org has this patch in it, so
the next release of libpcap from tcpdump.org should have it; hopefully
the HP-UX Porting and Archive Centre will switch to that version when it
comes out, and people will just be able to push a few buttons to get an
Ethereal that works on HP-UX.)

1) aclocal expects autoconf/automake macros to be hidden;
2) GTK+ hid its autoconf/automake macros;
and, if both places exist but aren't the same directory, returns a "-I"
flag to tell aclocal to look in GTK+'s directory.
Then have "autogen.sh", and Makefiles in directories with "acinclude.m4"
files, use that script and pass what flag it supplies, if any, to
aclocal.
This should, I hope, avoid problems such as those FreeBSD systems where
GTK+ was installed from a port or package (and thus stuck its macros in
"/usr/X11R6/share/aclocal") but aclocal doesn't look there.
(It doesn't solve the problem of somebody downloading and installing,
say, libtool from source - which means it probably shows up under
"/usr/local", with its macros in "/usr/local/share/aclocal" - on a
system that comes with aclocal (meaning it probably just looks in
"/usr/share/aclocal", but that may be best fixed by, whenever you
download a source tarball for something that's part of your OS,
configuring it to install in the standard system directories and
*overwriting* your OS's version.)

<arpa/inet.h>, but is, in some fashion, declared differently from the
way we declare it in "inet_v6defs.h", but "inet_ntop()" isn't defined,
so we include "inet_v6defs.h" in "inet_pton.c", which causes
"inet_pton.c" not to compile as we get a collision between the two
declarations.
Move the declaration of "inet_aton()" to "inet_aton.h", define
"NEED_INET_ATON_H" iff we didn't find "inet_aton()" in the system
libraries, and include "inet_aton.h" in the callers of "inet_aton()" iff
"NEED_INET_ATON_H" is defined, so that it doesn't get declared by us if
"inet_aton()" is defined by a system library (which hopefully means it's
declared in <arpa/inet.h> instead).

same directory as the "manuf" file ("/etc" or "/usr/local/etc", most
likely).
Add a mechanism to allow modules (e.g., dissectors) to register
preference values, which:
can be put into the global or the user's preference file;
can be set from the command line, with arguments to the "-o"
flag;
can be set from tabs in the "Preferences" dialog box.
Use that mechanism to register the "Decode IPv4 TOS field as DiffServ
field" variable for IP as a preference.
Stuff that still needs to be done:
documenting the API for registering preferences;
documenting the "-o" values in the man page (probably needs a
flag similar to "-G", and a Perl script to turn the output into
documentation as is done with the list of field);
handling error checking for numeric values (range checking,
making sure that if the user changes the variable from the GUI
they change it to a valid numeric value);
using the callbacks to, for example, update the display when
preferences are changed (could be expensive);
panic if the user specifies a numeric value with a base other
than 10, 8, or 16.
We may also want to clean up the existing wired-in preferences not to
take effect the instant you tweak the widget, and to add an "Apply"
button to the "Preferences" dialog.

only the dissector source files, not the header files; that way you
don't feed the header files to "make-reg-dotc", as "make-reg-dotc" won't
find any registration routines there so there's no point in feeding
header files to it.
Doing so means that we can make "DISSECTOR_OBJECTS" in "Makefile.nmake"
by doing
DISSECTOR_OBJECTS = $(DISSECTOR_SOURCES:.c=.obj)
rather than separately enumerating the object files, as Nmake supports
System V "make"-style substitution.
This should let users who change "DISSECTOR_SOURCES" in one of those
files just copy it to the other file.

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. :-)
