This patch adds support for LIN (Local Interconnect Network) as
well as support for:
- Signal PDUs on LIN
- ISO 15765 (ISO TP) on LIN
- TECMP transported LIN is handle like LIN
LIN is a simple automotive fieldbus to connect for example simple
sensors and actuators to an electronic control unit.
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.
Allows adding one or more capture comments to a new pcapng file when
tshark is reading from a file. Currently, tshark only allows setting one
capture comment, and that only when doing a live capture.
The use case for this feature is given in bug #15005.
I decided to allow multiple capture comments to match the same ability
in `editcap`.
To allow this change, I changed the function signature of
`process_cap_file()` so it takes a `capture_options` struct instead of
individual parameters that affect the capture.
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.
In the Windows merge request build job, don't pass
/consoleloggerparameters:PerformanceSummary;NoSummary to msbuild. It
makes the output more verbose and in turn makes errors more difficult to
find.
For iptrace files, there's always a direction indication (which also
means that the flags field will never be zero - "outbound" and "inbound"
both have non-zero values - so the test for non-zero always succeeds, so
it's not even a useful test).
For Sniffer Ethernet/FDDI/synchronous serial line files, and for Peek
classic files, there are always flags; they might be zero if there were
no errors, but that doesn't mean that the lack of errors shouldn't be
noted with a flags field.
While we're at it, shuffle creating of the block next to the setting of
the record type - the block and record type should match, so the two
operations are doing related things.
Add "SYSTEM" to "target_include_directories(version_info ...", which
keeps

Currently there can be multiple dlm messages in one tcp segment and in
some cases dlm message can be overlapped between two segments. The main
fix would be that we can now dissect multiple dlm messages if they
appear in one tcp segment. It's still own as one message in the "packet
flow" but in tree view it will be displayed as multiple messages which
are not visible.
For sctp the problem still exists, although there can't be overlapped messages.
Revert change to format_size() added in
f509a83381. This commit broke formatting
with spaces and introduced some dead code.
Also replace unnecessary call to format_size_wmem() and remove
unnecessary casts (since our warning settings were fixed in the
mean time).
Extend sharkd_dissect_request() so that it can replace
sharkd_dissect_columns().
Have it return a status indicating success, invalid frame number, or
read error, so that the caller knows what the problem is.
Pass it pointers to the wtap_rec and Buffer to use when reading packets
from the file, so that if it's called in a loop iterating over all
frames, those structures can be initialized once, before the loop, and
cleaned up once, after the loop, rather than doing both once per loop
iteration.
Pass pointers to the read error code and additional read error
information string pointer, so that, on a file read error, that
information is available to the caller.
Get rid of sharkd_dissect_columns(); instead, use
sharkd_dissect_request(), with code from the loop body pulled into a
callback routine. Fix that code to correctly determine whether the
current frame has any comments, rather than just treating all frames
that have blocks as having comments.
Use _U_ to mark arguments as unused, rather than throwing in a
(void) variablename;
statement.
Move some variables used only within a loop into the for() statement or
the loop body.
epan/CMakeLists.txt set both SYSTEM PUBLIC and SYSTEM PRIVATE for
GLIB2_INCLUDE_DIRS. The PUBLIC keyword adds it to the
INTERFACE_INCLUDE_DIRECTORIES property, which is only appropriate for
includes that we ship with Wireshark, so remove that one. Make
GLIB2_LIBRARIES private as well.
Fixes#17477.
wmem has many assertions during dissection, these are assumed to have
a measurable performance impact so remove assertions with
WS_DISABLE_ASSERT, like is done elsewhere.
We don't use ws_assert() to avoid a dependency on wsutil.
g_assert_not_reached() does not have a performance impact and for
that reason should not be disabled.
This allows wsutil to depend on wmem without introducing a circular
dependency.
Although wmem is included in epan it is in many ways an independent
library and it should remain so.
