Guy Harris 44c0624bd9 Add a WIRESHARK_RUN_FROM_BUILD_DIRECTORY environment variable on UN*X;
if set, and if the program isn't running with additional privileges,
it'll treat the directory in which the program is found as the data
directory.

If, on Windows, the version-number subdirectory of {data
directory}\plugins doesn't exist (which is assumed to mean that the
program is being run from the build directory), or if, on UN*X,
WIRESHARK_RUN_FROM_BUILD_DIRECTORY is set, the plugin directory is the
"plugins" subdirectory of the data directory, and all subdirectories of
that directory are scanned for plugins, as the "plugins" subdirectory of
the build directory contains subdirectories for the plugins; this means
that if we're running from the build directory, we'll find the plugins
we built in the build tree.

When generating the wireshark-filter man page, run tshark with
WIRESHARK_RUN_FROM_BUILD_DIRECTORY set, so it uses the plugins from the
build to generate the list of filters.

that needs libwireshark needs to have happen, so dissectors can register
GUIDs in that table).

Ulf Lamping 642467ad5c I'm adding the "Expert Info" prototype now, as it seems to be in a state where others might have a look and probably already find it useful :-). Anyway, we can easily disable it at one or two places in the code if it get's in our way of a new release.
Please see: http://wiki.ethereal.com/Development/ExpertInfo for a complete overview of the intended feature and it's current state of implementation.

While I'm working on this, I've also added some more status result codes to the DCE/RPC and DCOM dissectors.

Ronnie Sahlberg c841beb71b EMEM : a simple and FAST api to allocate memory that will be automatically freed() when the next packet is dissected.
This offesr memory allocation with a packet  scope making memory leaks less likely and memory management faster.


Add initialization calls for both tethereal and ethereal.

Convert the ip_to_str() function to use this and avoid doing the silly rotating buffers thing it previously did.


We also need an equivalent set of functions for allocation with capture file scope (free when next capture is loaded) but i dont know where to put the free_all call.

Guy Harris 8a8b883450 Set the svn:eol-style property on all text files to "native", so that
they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

Guy Harris d209115ba3 Add a "report_failure()" routine to allow dissectors to report arbitrary
errors to the user.  Use that, rather than "g_warning()", in the
Diameter dissector to report errors reading the dictionary.

Make the format argument to "simple_dialog()" a "const" pointer.

Fix up the read-error message in Tethereal to end with a newline.

If a simple dialog is requested before the main window or the
capture-control window is popped up, queue it up and pop the queued
messages up once the main or capture-control window is displayed.

Guy Harris 121f06fab7 Make "epan_init()" take, as additional arguments, pointers to routines
that dissectors should call to report file open and read errors, and
have "report_open_failure()" and "report_read_failure()" call through
those pointers, rather than being defined and exported by the
application using libethereal - instead, the application would define
those functions and pass pointers to them to 'epan_init()".

Move "report_err.h" to the epan directory, as the functions it declares
are now part of the libethereal API.

Gerald Combs 1d9b54fc07 Add support for asynchronous DNS updates using the GNU ADNS library.
Support can be enabled at configure time by using "--with-adns=DIR".
If support is enabled, async queries happen whenever host name resolution
is enabled.  Do we need a separate preference for async queries?

Currently, only IPv4 reverse queries are supported.  I can add IPv4 forward
lookup support, but I don't have any way to test IPv6 queries.

protocols (where there's a virtual circuit ID of some sort in packets)
what conversations are for protocols ultimately running atop
connectionless network layers.  Have circuit type and ID values in the

Have the Frame Relay dissector set the circuit type and ID values, and
have the Wellfleet compression protocol set up circuit information and
store compression information with the circuit.

A little work still needs to be done on the new NCP dissector -- make
some of the COL_INFO texts more useful, handle a Unicode issue, and
modify some of the cases that use "request conditions".
But the NCP dissector as it stands is very usable now.

Note: I didn't merge in the PROTO_LENGTH_UNTIL_END macro... I wanted
to think about the various possible macros and review an email conversation
I had with Guy on the subject.

Guy Harris 6a21dc7e44 Don't give tvbuffs names; instead, give data sources names, where a
"data source" has a name and a top-level tvbuff, and frames can have a
list of data sources associated with them.

Use the tvbuff pointer to determine which data source is the data source
for a given field; this means we don't have to worry about multiple data
sources with the same name - the only thing the name does is label the
notebook tab for the display of the data source, and label the hex dump
of the data source in print/Tethereal output.

Clean up a bunch of things discovered in the process of doing the above.

Gilbert Ramirez 791f5774d0 Provide for per-protocol-tree data in the proto_tree code.
Put a hash-table of "interesting" fields in the per-proto-tree data.
The dfilter code records which fields/protocols are "interesting" (by which
I mean, their value or existence is checked). Thus, the proto_tree routines
can create special arrays of field_info*'s that are ready for the dfilter
engine to use during a filter operation.

Also store the "proto_tree_is_visible" boolean, renamed "visible", in
the per-proto-tree data.

Move epan_dissect_t to its own header file to make #include dependencies
easier to handle.

Provide epan_dissect_fill_in_columns(), which accepts just the epan_dissect_t*
as an argument.

epan_dissect_new() needs to be followed by epan_dissect_run() for the
dissection to actually take place. Between those two calls,
epan_dissect_prime_dfilter() can be run 0, 1, or multiple times in order to
prime the empty proto_tree with the "intersesting" fields from the dfilter_t.

Guy Harris 23319ff023 Move the pointer to the "column_info" structure in the "frame_data"
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.

Gilbert Ramirez 6542c18172 Remove proto_tree from capture_file and PacketWinData, since they
already contain a pointer to an epan_dissect_t, which contains
the proto_tree.

Routines calling epan_dissect_new() do not create their own
proto_tree via proto_tree_create_root(); instead, they pass a boolean
to epan_dissect_new() telling it whether it should create the root
proto_tree.

Gilbert Ramirez 8743a4a8a7 Remove the global packet_info called "pi". Dissectors now only
access their own "pinfo". A packet_info is stored in epan_dissect_t,
which is created for the dissection of a single packet.

GUI functions which need to access the packet_info of the currently
selected packet used to use "pi"; now they use cfile.edt->pi. cfile's
"edt" member is the epan_dissect_t of the currently-selected packet.

The functionality of blank_packetinfo() was moved into
dissect_packet(), as that's the only place that called blank_packetinfo(),
after a spurious call to blank_packetinfo() was removed from
packet_list_select_cb().

Ed Warnicke f5cf9c8dca Added two new arguments to epan_init() and proto_init() to
allow the passing of register_all_protocols() and
register_all_protocol_handoffs() through epan_init() to proto_init().
This allows the removal of the compile time dependence of proto.c

dissector_handle for frame_dissector.  Changed the order of function
calls in epan_init() to allow for this change ( it sucks to look up
a dissector when none are registered ).

Gilbert Ramirez 8f1fff2e6a Create a more modular type system for the FT_* types. Put them
into epan/ftypes.

Re-write display filter routines using Lemon parser instead of yacc.
Besides using a different tool, the new grammar is much simpler, while
the display filter engine itself is more powerful and more easily extended.

Add dftest executable, to test display filter "bytecode" generation.
Add option to "configure" to build dftest or randpkt, both of which are not
built by default.

Implement Ed Warnicke's ideas about dranges in the new display filter and
ftype code.

Remove type FT_TEXT_ONLY in favor of FT_NONE, and have protocols registered
as FT_PROTOCOL. Thus, FT_NONE is used only for simple labels in the proto tree,
while FT_PROTOCOL is used for protocols. This was necessary for being
able to make byte slices (ranges) out of protocols, like "frame[0:3]"

Win32 Makefile.nmake's will be added tonight.

Guy Harris e7ea7a34e9 Clean up the dissector registration up a bit - arrange that all plugins
be loaded and their initialization routines called in right after we
call the initialization routines for built-in dissectors, but don't call
their handoff registration routines yet, and then call the handoff
registration routines right after calling the handoff registration
routines for built-in dissectors.

Do all that in "proto_init()", rather than "epan_init()".

That way, we call all dissector registration routines together, and then
call all dissector handoff registration routines together; all the
registration routines are called before any handoff registration
routines, as is required, and, as "proto_init()" is called by
"epan_init()" before "dfilter_init()" is called, all filterable fields
have been registered before "dfilter_init()" is called, and no plugins
have to call "dfilter_init()" themselves to get their fields registered.

Remove pointers to "dfilter_init()" and "dfilter_cleanup()" from the
plugin address table, as plugins shouldn't be calling them any more, and
remove calls to them from plugins.

Guy Harris cba377df3c Give libethereal its own configuration file, and have that configuration
file, rather than the top-level Ethereal configuration file, check for
"inet_aton()", "inet_pton()", and "inet_ntop()".  Then make its
Makefile.am include the appropriate object files if necessary.
Otherwise, they don't get built and put into libethereal, and therefore
attempts to link with anything in libethereal that uses them fail on
platforms that lack ethem, causing the build to fail.

That means a bunch of things need to be fixed to cope with libethereal
having its own "config.h" file; this means removing the include of
"config.h" from some libethereal header files.  Move the definitions of
the path names used only by "resolv.c" to "resolv.c" from "resolv.h" (so
"resolv.h" doesn't need "config.h", define HAVE_PLUGINS in the configure
script (so we don't have to include it in "plugins.h" to check whether
HAVE_DLFCN_H is defined).

Unfortunately, stuff outside libethereal needs to know PLUGIN_DIR; for
now, define that in the top-level configuration file, and have Ethereal
and Tethereal pass it as an argument to "epan_init()" - that should be
cleaned up at some point.

Remove from the top-level configure script checks for things used only
in libethereal.

Gilbert Ramirez e69b5278aa Implement epan_dissect_new() and epan_dissect_free(). These are the
"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"
