Guy Harris 2ee483a222 Move the Winsock initialization and cleanup to wsutil routines.
Those routines exist on both Windows and UN*X, but they don't do
anything on UN*X (they could if it were ever necessary).

That eliminates some #ifdefs, and also means that the gory details of
initializing Winsock, including the Winsock version being requested,
are buried in one routine.

The initialization routine returns NULL on success and a pointer to a
g_malloc()ated error message on failure; report the error to the user,
along with a "report this to the Wireshark developers" suggestion.

That means including wsutil/socket.h, which obviates the need to include
some headers for socket APIs, as it includes them for you.

Guy Harris bbc8cbfb9c If you use data_file_url(), you must first call init_progfile_dir().
And if you call init_progfile_dir(), you must call
init_process_policies() before that.

And even if you *don't* use data_file_url(), you might use it in the
future, or you might use other calls to get data file paths, so make
*all* the extcap programs make those calls.

(Yes, this is important on macOS, for example; it may also be important
on Windows.  On other UN*Xes we may just compile in the data file path,
but that's not true on *all* our platforms.)

João Valverde a3991874eb CMake: Replace PACKAGELIST magic
This is more explicit and easier to read with slightly better locality
while using less code.

Also less awkward when the package doesn't fit the narrow package list
expectations.

The ws_find_package() macro doesn't include all the status messages. The
choice was to rely on standard find_package() and feature_summary() output
and be less verbose.

Avoid polluting the CLI build interface. Per target include paths and
macro definitions are preferred.

Because this patch intentionally removes the global CMAKE_*_FLAGS
and include_directories() usage in favor of target properties, some
untested build configurations may inadvertently break because of
missing ${PACKAGE}_INCLUDE_DIRS or ${PACKAGE}_DEFINITIONS. This
required a manual review of dependencies that might have been
incomplete.

${PACKAGE_VAR}_LINK_FLAGS seems to be unused.

Changing the CMake Qt code to use more modern CMake component syntax
is left as future work.

Peter Wu 5cc461490d CMake: use object libraries to avoid redundant builds
Some source files are duplicated via add_executable. Assuming that these
are not affected by target-specific preprocessor macros, they can be
built only once and shared among executables.

In one configuration, this reduces the number of object files by 55
(cli_main.c and version_info.c alone were built 15 times each).

Removes the version dependency from each target since the 'version_info'
target can now declare this dependency. Remove CLEAN_C_FILES from extcap
since it is not used to set -Werror. Due to removing some files from
wireshark_FILES (and others), these are no longer part of checkAPIs
though. Hopefully that is acceptable.

Peter Wu e2e5b01d77 cli_main: remove real_main from stack traces for non-Windows
Restore the "main" name since that is used everywhere else except for
Windows. On Windows, "main" is renamed via a macro to avoid a conflict
with "wmain" and to allow it to be called in cli_main.c.

For those wondering, GUI applications (such as Qt) have a different
entry point, namely WinMain. In Qt5, src/winmain/qtmain_win.cpp defines
WinMain, but seems to convert its arguments from Unicode to CP_ACP
(ASCII). It might not support UTF-8, but I did not verify this.

Guy Harris a34cc98b2a Put the main() and wmain() routines for CLI programs into a separate file.
That means that code is only in one place, rather than having copies of
it in each of those programs.

CLI programs that, on Windows, should get UTF-8 arguments rather than
arguments in the local code page should:

	include the top-level cli_main.h header;

	define the main function as real_main();

	be built with the top-level cli_main.c file.

On UN*X, cli_main.c has a main() program, and just passes the arguments
on to real_main().

On Windows, cli_main.c has a wmain() function that converts the UTF-16
arguments it's handed to UTF-8 arguments, using WideCharToMultiByte() so
that it doesn't use any functions other than those provided by the
system, and then calls real_main() with the argument count and UTF-8
arguments.

option. Presenting verbose as an available option makes Wireshark
trying to retrieve the value of this option. As the option is not

For reference the problem happens due the unfortunate combo of
these two patches:
v2.3.0rc0-1108-gb83ea46 ("extcap: put missed parameters into the help")
v2.9.0rc0-2431-g945d441 ("extcap: fix return value in extcap_base_parse_options().")

Mikael Kanstrup 51fb5081b3 androiddump: Add packets with same encap type as used when open wtap
Already when selecting the extcap interface to use the encap type is

WTAP_ENCAP_WIRESHARK_UPPER_PDU.

This conversion break tcpdump function for all but ETHERNET interface
type. For example NLMON and 802.11 radiotap interfaces does not work.

This problem has probably been there since quite a while back but was not
seen (in the sense that current capture looked OK). Though when:

"3aec5e1 Catch attempts to write multiple encapsulation types if unsupported."

got applied the encap type mismatch is now detected and packet capture stops.
As encap type is known already when selecting the interface to use, fix
this by simply reusing the initial value when dumping the packets.

This:

1) means that we don't have to flag the compression argument with a

2) leaves space in the interfaces in question for additional compression
types.

(No, this is not part 1 of an implementation of additional compression
types, it's just an API cleanup.  Implementing additional compression
types involves significant work in libwiretap, as well as UI changes to
replace "compress the file" checkboxes with something to indicate *how*
to compress the file, or to always use some other form of compression).

David Kreitschmann 11ba10dd4b Fix build paths for cmake's Xcode project generator on macOS.
Multi-configuration generators (such as Xcode or VS) append the current build configuration to most paths (eg. Debug/Release). Currently this results in inconsistent paths for the application bundle and the included command line tools. This commit sets the correct path information for multi-configuration generators for macOS application bundles. The standard Makefile behaviour is untouched.

One Windows specific configuration was changed, as it was conflicting with these changes. This needs to be checked before merging.

Additionally the wrapper scripts are omitted for Xcode, as the path to the binaries depends on the configuration chosen in Xcode. Therefore it is not viable to create these scripts in the cmake run.

Mikael Kanstrup 2fb9c8244e androiddump: Read btsnoop header separately from rest of data
The code to read and skip btsnoop header was written in a way where
it reads up to PACKET_LENGTH bytes of data, skips the header, then
move rest of data back start of buffer. So far so good. The code
then resets number of bytes used in buffer making it skip rest of
all data read.

Many times this works fine but only by luck. When there's no data
transfers first recv call will always only return the header
(sender side writes header separately right after accept).

When data transfers are ongoing first recv call will return both
header and data. Then initial data is lost but more importantly
risk parsing data with invalid offset.

Fix by reading btsnoop header separately from rest of data.

Florian Bezold bfef57ebb7 androiddump: Fix and simplify tcpdump capture
1. Use "exec:" ADB command to get raw (non-PTY) tcpdump output
This is also supported on Android devices before Android 7, and is a
much easier approach than testing the new "shell,raw:" command and
falling back if unsupported. This basically undoes commit 5ebc3277.

2. Pass "-U" to tcpdump to prevent on-target buffering
Before using the "shell,raw" approach in commit 5ebc3277, I tried the
"exec:" command already, but experienced extreme buffering of the
tcpdump output, which is unacceptable for live trace viewing.
Turns out, the buffering is determined "automatically" by libpcap:
- When running in a PTY, output is flushed fast for viewing
- When _not_ in a PTY, output is not flushed and thus heavily buffered.
The "exec" command obviously doesn't use a PTY.
Fortunately, tcpdump has a "-U" option to flush the output after each
catpured packet, which is exactly what we need.

3. Ignore tcpdump stderr output
Enabling "-U" caused androiddump to fail, because it happened that the
tcpdump stderr logs were mixed with the stdout data. (We were probably
lucky this didn't happen without -U as well).
To fix this, we just ignore stderr completely by adding "2>/dev/null" to
the tcpdump command.

4. Get linktype from pcap global header
The stderr logs were previously parsed to get the textual linktype.
This is now replaced by a simpler & less fragile approach: tcpdump
prints the global pcap header, which contains precicesly the linktype
info we need.

5. Parse pcap global header magic correctly for timestamps & endianness
The previous code only supported the "classic" pcap header magic and
might also been incorrect on big-endian host machines.
Now, endian handling is simplified and we can detect the "nanosecond
timestamp" magic values as well.
This fixes the problem that extcap_dumper_dump expects *nano*second
timestamps, but the previous code supplied *micro*seconds if on-target
tcpdump outputs microseconds.

6. The parsing simplifications above allowed the main loop for tcpdump
capture to be simplified considerably.

Mikael Kanstrup bde402840f androiddump: Fix crash in add_tcpdump_interfaces
If there's a network interface on the device without the 'flags'
field and at the same time exist other network interfaces
with the 'flags' field present a null-dereference happens accessing
the non-matched regex flags field.

Fix crash by adding explicit null check to ensure (optional) regex
group really matched.

Florian Bezold 7dcf57719f androiddump: Support older on-target tcpdump versions
The output of 'tcpdump -D' only outputs interface flags from Android 7
onwards. Since it would be sad to lose the great androiddump support for
all older devices because of this, the logic is extended so that it
lists all interfaces if no '[' and ']' is found in the output.

Also, the used regex seemed to require an interface description, which
might not exist (even with new tcpdump versions). Now, interfaces
without description are not filtered.

Florian Bezold 5ebc3277ed androiddump: Fix adb tcpdump PTY CR/LF handling
Devices running Android >= 7 have a different adb shell handling than
before:
- Before Android 7, adb always runs shell commands in a PTY
  (pseudoterminal), which automatically converts all \n to \r\n
- Since Android 7, adb no longer uses a PTY if a command is directly
  started (like 'tcpdump' in our case).

The original androiddump code reversed the PTY \r\n handling as for
older devices. Commit 66507b9 for bug 13510 removed that which supported
newer devices while breaking all older devices.

This fix tries to support both by first trying to use the new
"shell,raw:" adb command syntax. If that succeeds, adb/device must
support non-PTY shells and we don't reverse any \r\n.
If that fails, it's most likely an older device, and we fall back to the
original "shell:" command and enable \r\n reversal.

(To prevent misleading error popups in Wireshark, the warning log in
adb_send when the first attempt fails is changed to a debug log).

João Valverde 995812c5f1 Refactor plugin registration and loading
Put different types of plugins (libwiretap, libwireshark) in different
subdirectories, give libwiretap and libwireshark init routines that
load the plugins, and have them scan the appropriate subdirectories
so that we don't even *try* to, for example, load libwireshark plugins
in programs that only use libwiretap.

Compiled plugins are stored in subfolders of the plugin folders, with
the subfolder name being the Wireshark minor version number (X.Y). There is
another hierarchical level for each Wireshark library (libwireshark, libwscodecs
and libwiretap).

The folder names are respectively plugins/X.Y/{epan,codecs,wiretap}.

Currently we only distribute "epan" (libwireshark) plugins.

João Valverde 262a84c384 Fix (and chop) static build option
This sets the scope of the static build option to Wireshark support
libraries only.

Before the patch:

Static plugins don't work with CMake and autotools.

autotools static build is broken, and most likely will always be, as
building Wireshark all-static is difficult and time-consuming.

After the patch:

For CMake Wireshark will be built with static or shared libraries and
dynamic plugins. Everything just works. CMake apparently doesn't want
you building static and shared libraries at the same time.

For autotools Wireshark will be built with shared libraries by default.
--disable-shared and --enable-static options work as usual. Dlopened
plugins are not built if --disable-shared is given to configure (to
disable shared libraries). This is a limitations imposed by libtool.

Tested on Linux. This removes broken support for building plugins
statically.

for this option was removed by commit:

9328eb6 androiddump: Register interfaces when list interfaces

A side effect of not implementing the option is that dumpcap is
then also called to try to retrieve interface capabilities
for all androiddump interfaces. As extcap interfaces are not
local network interfaces errors like these are logged
whenever the interface list is refreshed:

              Please check to make sure you have sufficient permissions, and
              that you have the proper interface or pipe specified. ()

To avoid error prints and to fulfil the documented equirements for extcap
tools register a fake interface with what would be the properties of such
an interface.
