Netdude Changelog
========================================================================

Tue Nov 12 19:53:05 GMT 2002             Christian <christian@whoop.org>

- Fixed SNAP plugin to correctly fall back to hex editor when packet
  content isn't understood ...

------------------------------------------------------------------------

Tue Nov 12 17:49:24 GMT 2002             Christian <christian@whoop.org>

Doh -- forgot to mention the biggest change. Vastly improved the
robustness of the Netdude <--> tcpdump communication. Some testing with
other machines made me discover issues with packets that cause tcpdump
to output more than one line (ARRRGH for that!). On my home machine,
I somehow always get all the lines in one flush from tcpdump, even
though tcpdump is in line-buffered mode. On other machines, this is
not necessarily the case and thus my clist line number -- packet number
association goes boooom.

The proper way to fix this would be to add an option to tcpdump that
causes an fflush() after each written output so that I can rely on
all data being sent, but I want to avoid that as much as possible,
since Netdude should remain independent of tcpdump versions.

I am now using a hack as a workaround, that seems to work okay
everywhere: I can force a flush on the tcpdump side by sending new
data to tcpdump (see man setvbuf), so I'm sending a tiny dummy packet
to force a flush. Major grossness.

Also introduced robust write() and read() wrappers, based upon
writen() and readn() from Stevens's Unix Network Programming book.

------------------------------------------------------------------------

Tue Nov 12 17:43:56 GMT 2002             Christian <christian@whoop.org>

- Fixed a segfault when saving a file that was created via File->New...
- Improved performance when a large number of consecutive packets
  is selected in the GUI -- it is a waste of time to call
  nd_trace_set_current_packet() all the time!
- Minor other stuff...

------------------------------------------------------------------------

Fri Nov  8 17:27:51 GMT 2002             Christian <christian@whoop.org>

Let the protocol plugins use the raw data plugin when header data is
incomplete. It was meant to be that way right from the start ...

------------------------------------------------------------------------

Fri Nov  8 16:56:44 GMT 2002             Christian <christian@whoop.org>

Today a few new issues have been pointed out, mostly by Richard Guy Briggs
<rgb@conscoop.ottawa.on.ca>. Time to update that TODO list for 0.3.3 ...


------------------------------------------------------------------------

Thu Nov  7 15:50:03 GMT 2002             Christian <christian@whoop.org>

Fixed a stupid bug that caused options to appear one line off in
protocol headers such as IP and TCP. Leftover from when I experimented
with bit number indicators on top of every header ...


------------------------------------------------------------------------

Thu Oct 24 11:16:02 BST 2002             Christian <christian@whoop.org>

Added an autoconf macro AC_PATH_PCAP for the pcap checks, since I need
these checks in the plugin templates as well. Currently unsure how to
handle this best -- for now I'm just adding the m4 file to the package
and also to acinclude.m4. 

Upped the version to 0.3.3.

------------------------------------------------------------------------

Wed Oct 23 18:01:59 BST 2002             Christian <christian@whoop.org>

Final final commit :) Turns out glade segfaults whenever I try to
generate the code with text contained in the text area of the about
dialog. Setting it in the code now with a big fat fixme ...


------------------------------------------------------------------------

Wed Oct 23 15:39:01 BST 2002             Christian <christian@whoop.org>

Final commit for 0.3.2. New in this release:

- nd_packet_init_from_pcap(): I noticed this is necessary when you
want to initialize a packet that doesn't belong to a trace, which
is easy to encounter when writing pure read-in-write-out type plugins.

- The build issues on RedHat installations should finally be fixed, and
for the worst case, configure now provides --with-pcap-headers and
--with-pcap-lib.

------------------------------------------------------------------------

Wed Oct  9 17:07:19 CEST 2002            Christian <christian@whoop.org>

- Include the RPM spec file in the package.

------------------------------------------------------------------------

Wed Oct  9 16:19:54 CEST 2002            Christian <christian@whoop.org>

- upped to 0.3.1.
- fixed a typo in the IP plugin.

------------------------------------------------------------------------

Mon Sep 30 12:20:55 CEST 2002            Christian <christian@whoop.org>

The build was broken when pcap.h is installed in pcap/pcap.h. Should
be fixed now.

------------------------------------------------------------------------

Mon Sep 30 11:23:06 CEST 2002            Christian <christian@whoop.org>

A spec file to build RPMs, contributed by Pehr Anderson, pehr AT pehr
DOT net.


------------------------------------------------------------------------

Mon Sep 30 11:13:02 CEST 2002            Christian <christian@whoop.org>

God no! We're using the BSD license! I accidentally released 0.3 with
a COPYING file containing the GPL ... and here's our reason to release
0.3.1 asap :)

------------------------------------------------------------------------

Wed Sep 25 15:07:09 CEST 2002            Christian <christian@whoop.org>

Ooops -- sorry Noel :o)

------------------------------------------------------------------------

Tue Sep 24 14:07:10 CEST 2002            Christian <christian@whoop.org>

- Another documentation update.

------------------------------------------------------------------------

Mon Sep 23 20:58:29 CEST 2002            Christian <christian@whoop.org>

- Documentation update.

------------------------------------------------------------------------

Sun Sep 22 21:22:01 CEST 2002            Christian <christian@whoop.org>

- Build scripts cleanups. To enable/disable debugging in a central
location, there's now a --enable-debugging switch in the configure
script.


------------------------------------------------------------------------

Sat Sep 21 18:43:16 CEST 2002            Christian <christian@whoop.org>

- Retrieve as many network interfaces as actually exist
- Added --debug to enable debugging output
- Bunch'o'cleanups.

------------------------------------------------------------------------

Fri Sep 20 12:18:54 CEST 2002            Christian <christian@whoop.org>

- Fixed the fixme in nd_trace_sel_delete()
- Fixed a bug in nd_packet_update()
- Added more convenience callbacks, look how much shorter the plugin code
now is

Almost there. Almost.

------------------------------------------------------------------------

Wed Sep 18 11:52:15 CEST 2002            Christian <christian@whoop.org>

Cleanups before the release:

- pass make distcheck again
- sort plugin menu entries alphanumerically
- documentation updates

------------------------------------------------------------------------

Wed Sep 18 02:27:08 CEST 2002            Christian <christian@whoop.org>

Documentation updates -- explaining the hex and ASCII editors and how
to write a Netdude plugin. Also fixlets to the doco Makefile.

------------------------------------------------------------------------

Mon Sep 16 01:28:12 CEST 2002            Christian <christian@whoop.org>

Killer commit!

- Turns out I had to change a lot of code to add full support for
nested protocols (i.e. IP in IP, such as in ICMP errors etc). Arrgh.
The concept of a protocol and a protocol as it is found in packet
data are now separated things, allowing me to pass nesting info
everywhere I need it.

- Added ICMP plugin.

- tcpdump output now immediately updates when preferences change

- Fixed a bug in preferences when adding new files -- the data type
code in the preferences file *is* actually needed.

- Header fields can now be tinted yellow to indicate inconclusive
results, like when the correctness of a checksum cannot be determined
because not all data is present in the captured data.

- Minor speedups by a couple of avoided nd_packet_get_data()s.

- Fixes in the ARP plugin to display as much as possible and not
hide the entire tab only because the address length fields are
insanely large.

- Updated Glade file of main app: don't adjust width of up and
down arrows in large-number entry dialog.

I wonder how much I forgot? Anyway, apologies for the sizes of
the diffs ...

------------------------------------------------------------------------

Tue Sep 10 21:48:11 CEST 2002            Christian <christian@whoop.org>

- Documentation update. We're properly extracting documentation, have
a reasonable stylesheet and clean up properly. Started documentation
of Netdude API.

------------------------------------------------------------------------

Tue Sep 10 00:05:34 CEST 2002            Christian <christian@whoop.org>

- Added "New" item to the file menu to allow creation of empty traces
- Bugfixes in the clipboard code: when pasting packets, make sure they
are of the same pcap linktype, and adjust snaplen if necessary.
- Cleaner exit: close all tcpdump connections on exit
- Use nicer automatic filenames, enumerated automatically.

------------------------------------------------------------------------

Mon Sep  9 14:53:46 CEST 2002            Christian <christian@whoop.org>

- Pass make distcheck. I cannot even begin to describe how painful it
was to just make setting up a handful of links survive this. My GOD
how can the autoconf folks deal with this crap every day!

- Upped version to 0.3, getting ready for a release:)

------------------------------------------------------------------------

Mon Sep  9 02:57:46 CEST 2002            Christian <christian@whoop.org>

- removed the data type indicator in the preferences file, not needed.
- Documentation! Added a gtk-doc framework with a heavily modified
jade driver, a few images and a target to build an html tarball


------------------------------------------------------------------------

Fri Sep  6 19:19:24 CEST 2002            Christian <christian@whoop.org>

Refresh all tcpdump outputs when the user applies new preferences.

------------------------------------------------------------------------

Wed Sep  4 16:30:52 CEST 2002            Christian <christian@whoop.org>

- Cleaned up plugins to make them more flexible. They're no longer
simply called for each selected packet, but only have a general big
entry point, after which they can do anything they want.

- Fixed a bug in the large-number dialog that prevented cursor keys
from working correctly

- Changed api of the fix_packet()-Callback to make use of known
packet indices and return whether or not packet actually got modified.

------------------------------------------------------------------------

Wed Sep  4 01:48:55 CEST 2002            Christian <christian@whoop.org>

- Fixed a cleanup bug in the capture code
- Added a note to the TCP config tab
- Added the Netdude logo to the background

------------------------------------------------------------------------

Wed Sep  4 00:52:28 CEST 2002            Christian <christian@whoop.org>

My God. 14 hours straight. If this thing doesn't ship soon I'll need
a vacation.

- Added TCP state management, transmission control buffers. Used to
keep an eye on the figures used in calculating relative seq/ack
numbers.

- Added multiple tabs support to the config system by means of
configuration "domains". You can register your callback that
gets activated when the user clicks "Apply" or "OK" in the config
dialog.

- Added a config domain in the TCP protocol, to let the user choose
which level of update accuracy she wants re. TCP seq/acks.

- Added a packet number limiting mode to the capture module. As
with the other limits, you can now add a limit to the total number
of packets that will be kept in memory (i.e. the total number of
packets, since the captured trace is always kept completely in
memory at the moment). Very neat. Thanks for the hint, Daniel.

- Brushed up the splash screen a bit, fun fun :)

- Fixed a refcounting bug in the monospace widget administration
that I had in mind for a while.

- Added several optimizations to make use of packet indices when
available, to save the O(n) packet index lookup overhead.

That's probably mostly all, didn't mention all the new bugs this
introduces :)


------------------------------------------------------------------------

Fri Aug 30 17:28:51 CEST 2002            Christian <christian@whoop.org>

- Extended protocols to support multiple magics. Makes sense for
protocols like ARP and RARP which are basically the same thing except
for the opcodes ...
- Revamped protocol hashing to reflect changes
- ARP updates

------------------------------------------------------------------------

Thu Aug 29 23:06:30 CEST 2002            Christian <christian@whoop.org>

- Added ARP plugin
- changed number dialog callback to match the header field button ones,
so that redundant calls are eliminated
- small fixes to protocol plugins
- The apply to all-Button has moved. Its new address is in the status
bar. Stop by for a visit :)
- Updated ROADMAP
- Improved protocol navigation when jumping around in the packet list,
the protocol the user last selected manually is now remembered and
selected again, if possible.

------------------------------------------------------------------------

Thu Aug 29 01:07:43 CEST 2002            Christian <christian@whoop.org>

- Added a plugin providing Linux SLL support, which is used when traffic
is sniffed using the "any" interface.
- Protocol header tables can now also include fields which need to be
wrapped around, and I came up with a much cleaner algorithm than the
old one used for the options fields, which I've replaced as well
- Fixes to the option code in the IP and TCP plugins to make them more
robust when option length values are modified
- s/u_char/guchar/.

------------------------------------------------------------------------

Wed Aug 28 03:00:53 CEST 2002            Christian <christian@whoop.org>

- Added facility to remove config settings
- Fixed a bug in recently-used files

------------------------------------------------------------------------

Wed Aug 28 01:51:12 CEST 2002            Christian <christian@whoop.org>

- Live capture code basically finished. Still needs a little polishing,
but works great :) Fixed a few smaller bugs along the way.

------------------------------------------------------------------------

Mon Aug 26 17:54:46 CEST 2002            Christian <christian@whoop.org>

- Beginning of code for live data captures
- Refactored the file selection code -- it was still the same mess that
was 0.2 and is now all callback-based, the nd_dialog... stuff now
only does what it's supposed to.
- Fixed an evil casting bug in the protocol nesting code, how that
could ever work beats me.

------------------------------------------------------------------------

Mon Aug 26 02:37:57 CEST 2002            Christian <christian@whoop.org>

- Added possibility to iterate both ways over the protocols in a packet
- Fixed the checksum fix plugin to properly iterate inside-out :)

------------------------------------------------------------------------

Mon Aug 26 02:19:43 CEST 2002            Christian <christian@whoop.org>

- Properly maintain the list of monowidth widgets

------------------------------------------------------------------------

Mon Aug 26 01:53:05 CEST 2002            Christian <christian@whoop.org>

- Added TCP option support
- Moved TCP seq/ack dialog to nd_dialog, the dialog is really just the
normal number editing dialog, just for larger values.
- Added generic header field callbacks to nd_protocol.h for common
bit values
- Fixed timestamp support in IP options, editing works fine now, using
the new number dialog

TCP is almost finished, only TCB management still needed.

------------------------------------------------------------------------

Sun Aug 25 23:37:53 CEST 2002            Christian <christian@whoop.org>

- Fixed two segfaults in gtk hex editor (apparently gtk is mighty feeble
when a widget is frozen)
- Introduced special characters for unprintable and null, looks nicer
than simple dots.

------------------------------------------------------------------------

Fri Aug 23 14:32:18 CEST 2002            Christian <christian@whoop.org>

- Fixed refcounting bugs when cleaning up
- Added some debugging calls to help memory profiling, use -DMEMDEBUG

------------------------------------------------------------------------

Fri Aug 23 03:02:42 CEST 2002            Christian <christian@whoop.org>

- All TCP header buttons implemented
- Added an entry dialog to work around gtk's crappy GtkSpinButton :/

------------------------------------------------------------------------

Fri Aug 23 00:43:18 CEST 2002            Christian <christian@whoop.org>

- Hilight corresponding characters in the hex view.

------------------------------------------------------------------------

Thu Aug 22 23:48:20 CEST 2002            Christian <christian@whoop.org>

- When editing packet content in ascii mode in the hex editor, gray
out excess data. More convenient during editing, because excess data
isn't lost when characters are deleted afterwards.

------------------------------------------------------------------------

Thu Aug 22 15:21:48 CEST 2002            Christian <christian@whoop.org>

- The hex editor is fully functional. Yay!
- Bugfix: the header size checks in the protocol plugins were off by
one, so that pure TCP header packets (e.g. SYNs) were not displayed.

------------------------------------------------------------------------

Tue Aug 20 01:23:57 CEST 2002            Christian <christian@whoop.org>

Fixed a bug in the hex editor that caused the cursor to fall of the end
of ascii lines (caused by skipping newlines when the newline is the last
character in the packet). Also, don't try to print anything outside
of ascii [32, 127] except for newlines.

------------------------------------------------------------------------

Tue Aug 20 00:17:20 CEST 2002            Christian <christian@whoop.org>

I've rewritten the hex editor widget, gtk style. It could now be cut
out and put into a libgtkhex library with basically zero effort.
I've also added complete cursor navigation to the hex editor, which
was a ROYAL PAIN. Should work for both hex and ascii view, and both
in the hex and ascii parts of the hex view.

Now, what's left to do is make the key press events actually change
the displayed data and using Netdude you can literally type up packet
content :)

------------------------------------------------------------------------

Sun Aug 18 18:38:16 CEST 2002            Christian <christian@whoop.org>

Been busy and offline over the weekend :)

- Beginning of TCP plugin
- Added support for nested (tunnelled) protocols, right now only
IP supports multiple headers in one packet.
- Fixed Ethernet plugin to display the header only and not the
payload size. The other plugins don't do so either.
- Monowidth font can be changed via preferences
- When packets are copied to the clipboard, the  tcpdump output of
these lines is now available from the X cutbuffer. Should make it
a lot easier to put tcpdump output in emails etc.
- Started work on the hex editor.
- Changed void *header to guchar *header in the protocol callbacks

Also minor other stuff I probably forgot ...

------------------------------------------------------------------------

Thu Aug 15 01:36:22 CEST 2002            Christian <christian@whoop.org>

The tcpdump output of the currently selected trace now becomes the
selection, so you can paste it to other files etc.

------------------------------------------------------------------------

Wed Aug 14 19:42:28 CEST 2002            Christian <christian@whoop.org>

- UDP plugin, fully functional with checksum correction. Easy as pie
to code given the plugin template :)

- I've moved ICMP to 0.4 on the roadmap. I want to get this thing
out of the door, and TCP is still to be written ...

------------------------------------------------------------------------

Wed Aug 14 14:23:36 CEST 2002            Christian <christian@whoop.org>

IP plugin basically finished!

- small fixes to the fragmentation code
- IP fragment reassembly! This reassembler is much more flexible than
the old 0.2 one -- it reassembles basically as much as possible: any
consecutive fragments found in the current selection are reassembled.
Try fragmenting a handful of packets many times and select a few of
them :)

------------------------------------------------------------------------

Sun Aug 11 19:28:42 CEST 2002            Christian <christian@whoop.org>

- Forgot the x8 factor when setting the new fragment's offset.

------------------------------------------------------------------------

Sun Aug 11 00:35:07 CEST 2002            Christian <christian@whoop.org>

- IP fragmentation works, reassembly still to do.

------------------------------------------------------------------------

Tue Aug  6 16:14:50 CEST 2002            Christian <christian@whoop.org>

- Segfault fix, existence of menu item callbacks was not checked
- IP checksum correction works :)
- Warnings cleanup

------------------------------------------------------------------------

Tue Aug  6 15:41:28 CEST 2002            Christian <christian@whoop.org>

- IP options! Handles all options in RFC 791 and 2113, displaying all
fields of those options, you can also modify them of course. The
Gtk spinbutton strikes again, the crappy float handling prevents
errorfree handling of large ints, so I've disabled the editing of
some 32 bit fields.

- When selecting a recently used file from the menu, move it to the
front. Found a strange memory corruption bug while doing this, not
sure if the fix is correct.

------------------------------------------------------------------------

Fri Aug  2 03:05:34 CEST 2002            Christian <christian@whoop.org>

- When saving a file under a new name, add that name to the recently
used list.

------------------------------------------------------------------------

Fri Aug  2 02:52:13 CEST 2002            Christian <christian@whoop.org>

- fixed a segfault due to borked memory handling in the clipboard code
- use two lines for the payload indicator in the Ethernet plugin

------------------------------------------------------------------------

Tue Jul 30 16:10:23 CEST 2002            Christian <christian@whoop.org>

Oh joy!

- Added a raw data display protocol that now displays all those parts
of a packet as hex and/or ascii data for which no specific protocol
plugin could be found.

- Fonts for that hex viewer and the tcpdump output are now always set
to monowidth, no matter what the user's theme is. Making this
configurable is underway.

- Changed the header button registry to a simple hashtable per trace,
much cleaner, much more obvious.

------------------------------------------------------------------------

Tue Jul 30 00:12:06 CEST 2002            Christian <christian@whoop.org>

Added a separate facility for obtaining the GUI buttons from a
protocol's header definition. gtk_object_get_data() got too
messy.

------------------------------------------------------------------------

Thu Jul 25 00:35:47 CEST 2002            Christian <christian@whoop.org>

Yay! There appears to be a bug in CVS 1.11.p1 as well as 1.11.2 that
causes incorrect behaviour when the -F option is used (see
src/commit.c around line 429). I'm using -m in the script now.

------------------------------------------------------------------------

Thu Jul 25 00:33:19 CEST 2002            Christian <christian@whoop.org>

Okay. Let's see if this fixes the CVS script problems.

------------------------------------------------------------------------

Tue Jul 23 13:13:44 CEST 2002            Christian <christian@whoop.org>

* Added ECN support to the IP protocol.

------------------------------------------------------------------------

Wed Jul 17 15:48:24 CEST 2002            Christian <christian@whoop.org>

Lots of updates:

- IP plugin mostly finished (fragmentation + checksum correction todo)
- Protocol header field buttons can be togglebuttons as well
- fixes to Ethernet plugin (removed the checksum field .. *cough* :)
- fixed a segfault in the number dialog code
- added a crc-32 implementation. I was playing with the algorithm
  and figured who knows ...
- Added pointer from ND_Packet to ND_Trace, so each packet knows which
  trace it belongs to. Eats more memory per packet, but makes the code
  *so* much cleaner.
- autogen.sh got revamped and now uses shtool for nicer output
- Added a nifty little packet iterator that handles gui updates
  automatically.
- Number dialog can switch between dec and hex display
- Added a generic mechanism to create popup menus for the common case
  of protocol header fields with a particular set of common values
- Removed the protocol parameter from the header field and menu item
  callbacks, they're unnecessary.
- Added an IP address dialog. This violates the plugin principle, but
  I guess that there'll be enough plugins that benefit from it to move
  it into the main app.

*phew* :)


------------------------------------------------------------------------

Wed Jul 10 14:10:38 CEST 2002            Christian <christian@whoop.org>

Initial import of the IPv4 plugin (not yet functional), also added
the possibility to choose amon toggle buttons and normal buttons for
the protocols (IP's flags are represented through togglebuttons for
example).

------------------------------------------------------------------------

Wed Jul 10 13:41:24 CEST 2002            Christian <christian@whoop.org>

A few fixes to the Ethernet plugin -- mark trace as modified when values
change etc.

------------------------------------------------------------------------

Tue Jun 18 21:09:41 CEST 2002            Christian <christian@whoop.org>

- In order to allow plugins to build, they'll need Netdude's headers.
I've added a symlinked directory include/netdude/ from the toplevel
source dir that points to src/, and updated the Makefile.ams.

- Don't use our own local hook to install the stuff in pixmaps/, but
use the DATA directive.

make distcheck passes cleanly now.

------------------------------------------------------------------------

Tue Jun 18 19:01:53 CEST 2002            Christian <christian@whoop.org>

- Rewrite of the preferences management. It's now totally generic,
and to add new preferences you only have to modify exactly one place
in the code (the preferences table in nd_prefs.c), and possibly
the gui. Yay.

- Show a tooltip with a file's full name when the mouse rests over
a trace's tab label.

------------------------------------------------------------------------

Mon Jun 17 19:33:51 CEST 2002            Christian <christian@whoop.org>

- Added a dialog that asks the user whether he wants to overwrite
a file if it already exists

- Fixed a small bug that caused a '/' to be added to the save directory
every time Save As is clicked ...

------------------------------------------------------------------------

Mon Jun 17 19:29:36 CEST 2002            Christian <christian@whoop.org>

Adding german translation ...

------------------------------------------------------------------------

Mon Jun 17 02:33:16 CEST 2002            Christian <christian@whoop.org>

Fixed two bugs in the packet duplication code -- copy the end-of-data
pointers and the protocol combination as well.

------------------------------------------------------------------------

Mon Jun 17 02:13:05 CEST 2002            Christian <christian@whoop.org>

- Added a smart exit dialog. It should be one of the better ones I've
seen so far -- allows you to individually save modified traces, then
exit.
- changed raw access to GList's next pointer to g_list_next()
- GUI cleanups -- put generic dialog context into a frame


------------------------------------------------------------------------
