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
Instructions:
00000 CHECK_EXISTS ip
00001 IF_FALSE_GOTO 5
00002 CHECK_EXISTS tcp
00003 IF_TRUE_GOTO 5
00004 CHECK_EXISTS udp
00005 RETURN
After: ip and tcp or udp => (ip and tcp) or udp
Filter: ip and tcp or udp
Instructions:
00000 CHECK_EXISTS ip
00001 IF_FALSE_GOTO 4
00002 CHECK_EXISTS tcp
00003 IF_TRUE_GOTO 5
00004 CHECK_EXISTS udp
00005 RETURN
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.
The representation "~= has been superseded by "!==" with the same
meaning, making it superfluous and somewhat confusing. Deprecate
"~=" and recommend "!==" instead.
Update the text2pcap man page and the Import from Hexdump WSUG
page to clarify how to use it, for grammar, and to remove a few
things that are no longer relevant. (E.g., it's no longer the case that
files without an EOL don't work.)
Fix#15563, #15564.
Add BASE_SHOW_UTF_8_PRINTABLE and related function tvb_utf_8_isprint
for supporting fields of bytes that are "maybe UTF-8" (default or
SHOULD be UTF-8 but could be something else, with no encoding indicator),
such as SSID fields in IEEE 802.11 (See #16208), certain OctetString
fields in Diameter or PFCP, and other places where
BASE_SHOW_ASCII_PRINTABLE is currently used. Fix#5307
The beginning of the tshark manual talks about read filters and
using the -R option. Switch all that to display filters and -Y,
since that's the typical use now, with -R limited to two-pass
analysis.
Add an option to text2pcap to specify the encapsulation type
via wiretap encapsulation type short names instead of pcap
link layer types, similar to editcap.
Update the documentation to reflect this.
In text2pcap and Import from Hex Dump, allow fake IP headers with
the appropriate versions when the Raw IP, Raw IPv4, and Raw IPv6
encapsulations are specified. In such cases, do not add a dummy
Ethernet header.
Continue to reject other encapsulations besides these, Ethernet,
and Wireshark Upper PDU when appropriate. Add some checks for the
encapsulation type in text_import as well, instead of just assuming
that the callers handle it correctly.
Support all possible file formats that wiretap writes, using the
same "-F" flag that other CLI tools like editcap, mergecap, and tshark
support. Default is still pcap for now; a future commit will switch
to pcapng and remove the "-n" option, to match other CLI tools.
Add support in text2pcap for the regex mode added to "Import from
Hex Dump" in 3.6.0 The input and output indicators cannot (yet?)
be configured, and are set to the default of allowing any of "iI<"
for inbound and "oO>" for outbound. This reaches feature parity
between text2pcap and Import from Hex Dump, fixes#16724.
(There might be some more cleanups to do, including docs.)
Add information about the different kind of comparisons with
multiple fields to the wireshark-filter man page.
Add some minimal information to the user guide. It would be
nice to have a section dedicated to this with some examples.
Remove the '-d' option from text2pcap, and move the two levels
of debug messages in text2pcap and text_import to either
LOG_LEVEL_DEBUG or LOG_LEVEL_NOISY as appropriate.
Add docs/diagnostic-options.adoc, which is a snippet that documents our
various --log-* options. Include it in the dumpcap, rawshark, and tshark
man pages.
Make the ws_log_print_usage output more consistent.
Repeated words were found with:
egrep "(\b[a-zA-Z]+) +\1\b" . -Ir
and then manually reviewed.
Non-displayed strings (e.g., in comments)
were also corrected, to ease future review.
Currently used to define ssize_t on platforms that lack it.
Fix some Windows build errors caused by moving the definition into a
separate header.
Fix some narrowing warnings on Windows x64 from changing the definition
of ssize_t from long int to int64_t.
The casts in dumpcap are ugly but necessary. The whole code needs
to be rewritten for portability, or the warnings disabled.
