Remove the redundant BASE_FLOAT field display type. The name
BASE_FLOAT is meaningless and the value aliased to BASE_NONE.
Require BASE_NONE instead of BASE_FLOAT (corresponding to
the printf() %g format).
Add new float display types using BASE_DEC, BASE_HEX and BASE_EXP
corresponfing to %f, %a and %e respectively.
Add support for BASE_CUSTOM with floats.
Changes:
- The tool now recognizes which software is running on a device - IOS, IOS XE
or ASA. Based on it, it uses correct sequence of commands to setup
capture, read captured packets and clear the capture.
- The tool reads packets on the fly so you don't have to wait till
--remote-count of packets is reached.
- The tool reads timestamps from capture on the device for IOS and ASA (on
IOS-XE, there is no timestamp in dump).
- Except Windows platform the tool handles early stop of capture on the device
and clear of capture buffer on the device (it finish the capture).
- There are special interface names to allow the tool to generate
specific capture types.
- Documentation updated.
Closes#17672.
Harden the code a little and alternate the mac address to allow
the code to be used for testing conversation and endpoint dialog.
Also transmit integer values not as ascii representations and include
a data packet that allows for reassembly to be tested
Port the script that creates init.lua to Python3. The generated init.lua
removes one newline and adds another, otherwise the output is identical
to the Perl version.
Ping #18152.
Port the script that creates taps_wslua.c and taps.txt to Python3. The
generated taps_wslua.c has one less newline, otherwise the output is
identical to the Perl version. Make the "taps" configuration file an
ConfigParser / .ini file.
Ping #18152.
Use "True" or "TRUE" instead of "true" and remove case insensivity.
Same for false. This should serve to differentiate booleans a bit
more from protocol names, which should be using lower-case.
Support merging files with IDBs in the middle of the file.
Use wtap_get_next_interface_description when doing the initial
list of interfaces so that we can correctly get IDBs later.
Note that while IDB merge modes "any" and "none" work as expected, the
default "all" mode can't really work for IDBs in the middle of the file
without adding a two-pass mode. In "all" mode, if there are any such IDBs,
merge them with duplicates iff the interfaces at the beginning of the
files were merged.
Related to #15502 and #16542.
Add conversation_new_full and find_conversation_full, which take
arbitrary element lists instead of fixed addresses and ports.
Update the comments in conversation.h to be more Doxygen-conformant.
Update README.dissector.
Use the new functionality to add initial conversation support to the
Falco Bridge dissector.
For the upcoming 4.0 release, switch the default file format for
text2pcap to pcapng from pcap, to match other tools and the GUI
behavior. Update the documentation and release notes appropriately.
Deprecate the old -n flag; since pcapng is the default this has no
effect. Changing the output capture file format is supported with
the -F option, consistent with the other command line tools.
Related to #18009.
Add support to display filters for matching a specific layer within a frame.
Layers are counted sequentially up the protocol stack. Each protocol
(dissector) that appears in the stack is one layer.
LINK-LAYER#1 <-> IP#1 <-> TCP#1 <-> IP#2 <-> TCP#2 <-> etc.
The syntax allows for negative indexes and ranges with the usual semantics
for slices (but note that counting starts at one):
tcp.port#[2-4] == 1024
Matches layers 2 to 4 inclusive.
Fixes#3791.
Needed to format timestamp in #18038 - packet-cql.c
Mirrors changes made in !1924 - Add ENC_TIME_NSECS timestamp encoding
Documentation in README.dissector, proto.c, proto.h - could use
refresh in a different merge request.
This removes the limitation of having only two terms in an
arithmetic expression and allows setting the precedence using
curly braces (like any basic calculator).
Our grammar currently does not allow grouping arithmetic expressions
using parenthesis, because boolean expressions and arithmetic
expressions are different and parenthesis are used with the former.
Editcap accepts '-' for stdin or stdout, document that. Also change
an incorrect statement that claims that the '-v' flag writes to
standard output; it writes to standard error.
In most, if not all, programming languages logical AND has
higher precedence than logical OR. Apply the principle of
least surprise and do the same for Wireshark display
filters.
Before: ip and tcp or udp => ip and (tcp or udp)
Filter: ip and tcp or udp

Fixes "make install" to be relocatable using DESTDIR. For that
we cannot use an absolute path as intallation directory target.
This is useful mostly to implement packaging using CPack.
It is a bit awkward to configure a default CMAKE_INSTALL_PREFIX
using WiresharkConfig.cmake but it seems to be working OK.
The previous non-relocatable behaviour may still be useful. It is
relegated to a custom "copy_plugin" target.
Add support for masking of bits. Before the bitwise operator
could only test bits, it did not support clearing bits.
This allows testing if any combination of bits are set/unset
more naturally with a single test. Previously this was only
possible by combining several bitwise predicates.
Bitwise is implemented as a test node, even though it is not.
Maybe the test node should be renamed to something else.
Fixes#17246.
