Besides the obvious limitation of being unavailable on Windows,
the standard is vague about getopt() and getopt_long() has many
non-portable pitfalls and buggy implementations, that increase
the maintainance cost a lot. Also the GNU libc code currently
in the tree is not suited for embedding and is unmaintainable.
Own maintainership for getopt_long() and use the musl implementation
everywhere. This way we don't need to worry if optreset is available,
or if the $OPERATING_SYSTEM version behaves in subtly different ways.
The API is under the Wireshark namespace to avoid conflicts with
system headers.
Side-note, the Mingw-w64 9.0 getopt_long() implementation is buggy
with opterr and known to crash. In my experience it's a headache to
use the embedded getopt implementation if the system provides one.
Allow the hover selection to be either configured via context menu
or by pressing the Ctrl key while moving the mouse. The configuration
is stored via profile
"Follow Stream" functionality assumes that all data in a single packet
belongs to the same stream. That is not true for HTTP2 and QUIC, where
we end up having data from unrelated streams.
Filter out the unwanted data directly in the protocol dissector code with
a custom `tap_handler` (as TCP already does).
Close#16093
The related-packet drawing code currently intermingles the selection and the
drawing of the conversation "trace" lines and the indicators. Separating them
out -- so we make the decisions upfront and then do the drawing -- will help
with any future work in this area.
The Ubuntu build commented on some spelling errors in executable code
files. Fix the errors that don't come from external files containing
the spelling errors (USB product and vendor IDs, PCI IDs, ASN.1
specifications), and fix some errors that don't show up in the
executable code files (e.g., in comments and variable names).
Allow the user to select multiple packets, and
* add the same comment to all selected packets
* remove all comments from selected packets
A new comment is added to each packet, now that we support multiple
comments per packet.
This is one potential way to address #8713.
Save a list of all user options that were specified on the Wireshark
command line using the `-o` option. Reapply those preferences after
reloading Lua plugins. Fixes the behaviour given in #12331 wherein such
prefs were reset to the defaults, not the command-line values, when
reloading Lua plugins.
When the user changes a preference in the Wireshark UI, remove that
preference from the stored command line options, so it doesn't get reset
when Lua plugins are reloaded again.
If a graph is added it should be a single operation, not multiple setData operations
leading to a myriad of dataChanged signals to be fired, which in turn can hinder redissection.
Wireshark/tshark may be built without Lua support. This patch adds an
error message if the user specifies the `-X lua_script` command-line
argument to a program built without Lua support, so the user is not left
wondering why their script isn't working.
Without that, you could add a comment to a record in a file format the
reading code for which doesn't allocate blocks, but the comment doesn't
get saved, as there's no block in which to save the comment option.
This simplifies some code paths, as we're either using the record's
modified block or we're using the block as read from the file, there's
no third possibility.
If we attempt to read a record, and we get an error, and a block was
allocated for the record, unreference it, so the individual file readers
don't have to worry about it.
Set PacketDiagram as parent of QGraphicsScene so the scene is destroyed
together with PacketDiagram.
Dynamically allocate WiresharkApplication and explicitly call its
destructor when no longer needed. This results in deletion of
FunnelAction objects created in register_menu_cb() and QAction objects
created in TapParameterDialog::registerDialog(). For some reason, when
breakpoint was set inside WiresharkApplication destructor it would not
get triggered on exit, and so the child objects would get reported as
memory leaks.
Delete main window and application only after epan_cleanup(). This makes
lua plugins actually call ops during cleanup (e.g. destroy_text_window)
and makes it possible to free the memory allocated in FunnelStatistics
constructor.
Instead of creating endless loop and synchronizing using QWaitCondition,
execute the syntax worker check in its thread by emitting signal. The
syntax worker thread affinity is set to worker thread so the slots
handling takes place within the worker thread context.
This patch allows the profile importer to recover from a file too large
to import as well as adjusts the maximum allowed config file size.
Closes: #17504
When capture was longer (e.g. 800s), audio was decoded correctly, but
visual waveform was shown incorrectly. Reason was exceeding range of
guint32 during calculation. Calculation is now made in guint64 and then
put back to guint32.
Bug 17478 was caused by `wtap_rec.block` being allocated for each
packet, but not freed when it was done being used -- typically at the
end of a loop.
Rather than requiring each caller of `wtap_read()` to know to free a
member of `rec`, I added a new function `wtap_rec_reset()` for a
slightly cleaner API. Added calls to it everywhere that seemed to make
sense.
Fixes#17478
This header was installed incorrectly to epan/wmem_scopes.h.
Instead of creating additional installation rules for a single
header in a subfolder (kept for backward compatibility) just
rename the standard "epan/wmem/wmem.h" include to
"epan/wmem_scopes.h" and fix the documentation.
Now the header is installed *correctly* to epan/wmem_scopes.h.
Those routines can't add an option if there's no block to add it to;
this meant that neither the direction nor the sequence number would be
set when importing a packet.
Automated find/replace of wmem_packet_scope() with pinfo->pool in all
files where it didn't cause a build failure.
I also tweaked a few of the docs which got caught up.
fcntl.h appears to be available on all of our supported platforms,
including Windows. We've also been including it without HAVE_FCNTL_H
guards in a few places (e.g. sshdump.c) without any issues for some
time.
floorl is part of C99.
Don't store the comments in a capture_options structure, because that's
available only if we're being built with capture support, and
--capture-comment can be used in TShark when reading a capture file and
writing another capture file, with no live capture taking place.
This means we don't handle that option in capture_opts_add_opt(); handle
it in the programs that support it.
Support writing multiple comments in dumpcap when capturing.
These changes also fix builds without pcap, and makes --capture-comment
work in Wireshark when a capture is started from the command line with
-k.
Update the help messages to indicate that --capture-comment adds a
capture comment, it doesn't change any comment (much less "the" comment,
as there isn't necessarily a single comment).
Update the man pages:
- not to presume that only pcapng files support file comments (even if
that's true now, it might not be true in the future);
- to note that multiple instances of --capture-comment are supported,
and that multiple comments will be written, whether capturing or reading
one file and writing another;
- clarify that Wireshark doesn't *discard* SHB comments other than the
first one, even though it only displays the first one;
Spell out "DESCRIPTION" for the IDB description option, as it's spelled
out in the pcapng spec.
Put the #defines for various options in the same order as the block
types for them are in the pcapng spec.
Mark wsutil's includes SYSTEM PRIVATE. This exposed a lot of targets
that were indirectly picking up include paths via the wsutil target, so
add direct includes where needed. The G.722 and G.726 codecs were
implicilty including tiffio.h; find it explicitly instead.
Mark some of wsutil's libraries PRIVATE, but leave commonly-used ones
PUBLIC.
Ping #17477.
Add "SYSTEM" to "target_include_directories(version_info ...", which
