We keep our various packaging assets in the "packaging" directory. Move
the Debian assets there. dpkg-buildpackage doesn't seem appear to have a
"debian directory path" option, but symlinking worked in my test
container.

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

Add p_set_proto_data, which either updates our entry if we have a
proto+key match or adds an entry if we don't. Use it with
p_set_proto_depth. Document it and our other proto_data routines.

Rewrite ws_inet_pton{4,6} and ws_inet_ntop{4,6} without
GLib types.
Check for strerrorname_np() and use that is available,
to simplify error handling.
Add some minimal tests.
|
|
Encapsulate the feature requirements for strptime() in a
portability wrapper.
Use _GNU_SOURCE to expose strptime. It should be enough on glibc
without the side-effect of selecting a particular SUS version,
which we don't need and might hide other definitions.

Fixes a bunch of package warnings, and teaches the Debian package to
respect make install rules, and even more importantly to respect header
visibility rules, as defined by the build system. This prevents
private headers to be installed to the target system.
Remove the broken by design system that requires developers to
constantly fix headers by hand. Again the source of truth for which
headers are system headers is the build system, and that's what
any package must use, without requiring constant syncing of
installation rules in CMake and Debian.

Split ws_regex_matches() into two functions with better semantics
and remove the WS_REGEX_ZERO_TERMINATED symbol.
ws_regex_matches() matches zero terminated strings.
ws_regex_matches_length() matches a string length in code units.

For historical reasons our logging inherited from GLib the logging of
some levels to stdout. Namely levels "info" and "debug" (to which we
added "noisy").
However this practice is discouraged because it mixes debug output
with application output for CLI tools and breaks many common usage
scenarios, like using tshark in pipes.
This change flips the logic on wslog to make logging to stderr the
default behavior.
Extcap subprocess have a hidden dependency on stdout so add that.
Some GUI users may also have a dependency on stdout. Because
GUI tools are unlikely to depend on stdout for programatic output
add another exception for wireshark GUI, to preserve backward
compatibility.

Related with #17774.

Remove experimental new API.
Fix Netlink dissector to compile with normal proto tree API.
Closes #17774.

Extcaps require a log file when invoked in child mode. It also has
a specific flag to enable debugging, other that the wslog options.
Fix the logging to:
1. Enable debug log level if --debug is used.
2. Do not emit messages to the stderr if debug is enabled.
This brings extcap logging to the same feature level it had before
wslog replaced GLib logging.

Used with the GTK GUI, not used for a long time.

Remove ws_strdup_escape_char(). I don't think it is generic enough to keep,
and it does not seem very efficient either.
Remove string_replace(). This function was used in the GTK GUI.

Move epan_memmem() and epan_strcasestr() to wsutil/str_util.
Rename to ws_memmem() and ws_strcasestr(). Add compile time
check for a system implementation and use that if available.
We invoke those functions using a wrapper to avoid exposing
_GNU_SOURCE outside of the implementation.

C is notoriously difficult to bind from other languages
without additional metadata. The C ABI does not include
enums and macros that are an essential component of the
API.
To make Wireshark instrospectable and more binding friendly
include an introspection API to export enums and integer macros.
To avoid the tedious need to manually keep the code up to date
it uses the excellent pyclibrary python package to automatically
parse C headers and extract this data.
This is not a process that should be done automatically during
the build.
This could be used for example to replace most of the wslua
make-init-lua.pl perl script, which tries to do the same thing
using regular expressions.
Besides the downside of using Perl using regular expressions
is inferior to pyclibrary in 2 ways: 1) pyclibrary understands
most of C99 grammar so it is much more powerful; 2) pyclibrary
has a specific API to extract "values" (enums and constants)
automagically. We just need to take care to use only integer
values, for our purposes.

The headers in the libwiretap-dev package require headers from the
libwsutil-dev package, so ensure they're installed.

A number of protocols have IDs that can be reused that are used as
lookup keys. In most cases the frame number should be used as well
to differentiate repeat appearances of an ID. For response/request
matching, it is frequently useful to find the most recent frame number
(greatest value less than or equal to the current one) that contained
an ID.
We can achieve that by using a multimap that stores values with a given
ID in a tree keyed with the frame number. This works better than using
a map or a tree alone:
1) A map isn't ordered, so doesn't allow for less than or equal comparison.
2) Using a tree requires an ordering on all the ID components, and then
having to test all the components other than the frame number separately
for equality after retrieval.
Currently the multimap does not support inserting items without specifying
the tree key (and having the multimap generate a key), because the total
capacity of trees (including deleted nodes) is not tracked. If other use
cases are needed, this could be added later along with more generic
multimap support.
Use a multimap in ANSI MAP, ANSI TCAP, and GSM SMS, all of which need to
match lookup IDs that can be reused. Fix #7653.

Add result output to console log, in addition to intermediate debug
information. This allows tracing the result using the log only.

Blind attempt to fix Debian package brokenness managing
headers separately from install rules.
Global public headers that don't fit any of the Wireshark
libraries should be placed in include/.
Eventually the C files in the root dir should be placed somewhere
else as well (like src/) but this is not a priority.
Fixes #17726.

This function is unnecessary. Clients are receiving a wmem-allocated
buffer and have no need to know the length apriori.
|
|
Have these functions accept a zero max length to mean "display
the whole byte array". Change the max length parameter to receive a
number of bytes to print, not the length of the output character
string.
Adjust the macros bytes_to_str() and bytes_to_string_punct() to
produce the same output. Add more tests. Rename the functions to
bytes_to_str_maxlen() and bytes_to_str_punct_maxlen() because this is
an API break.

Add uat_set_default_values, which lets us provide default values for
fields that might be missing from the end of a UAT line. Set a default
value for the I/O Graph dialog's Y Axis Factor. Fixes the backward
compatibility issue described in #17623

Do the name check in one pass only, instead of two passes, one
for all letters and a second one to exclude upper case letters.

Probably it is still better to report the git version as the native package builds used to.
This reverts commit ba4bec7d0987c7e79c8deca6ad3f3fe8a1af586a.

When the user has manually registered to a port a dissector other than
the default subdissector (through Decode As, or the preferences
registered via dissector_add_uint_[range_]with_preference), try
those ports with a custom dissector first.
There's a few dissectors (e.g., GTP) that have port preferences
that haven't been migrated to use the DECODE_AS_ preferences for
various reasons; this won't change anything when their preferences
are changed from the default, though it can still work via Decode As.
Fixes #6223 and #12168.

|
|
Some enhancements and visual fixes to version 3 dissector are also included.
|
|
Shared libraries should not export symbols exported by other libraries to avoid
collisions.
Fixes #17645.
