Gerald Combs cec5991f40 Windows: Modernize our WSAStartup usage.
Make sure we link each application that calls WSAStartup with ws2_32.lib.
Pass version 2.2 to WSAStartup. Wikipedia says it was introduced in 1996,
so we should be OK.

Tomasz Moń b075b8c7f7 wsutil: Fix 30 seconds freeze if process fails to start
In ws_pipe_wait_for_pipe() on Windows, the WaitForMultipleObjects() waits
on the pending pipe connection events and process handle. If the process
handle is signalled, then it means that the process did exit without
connecting to the pipes.

The WaitForMultipleObjects() was not waiting on the process handle and thus
if the process did fail without connecting to pipes the Wireshark gui was
frozen for 30 seconds.

This change fixes the freeze by increasing the number of handles, so
WaitForMultipleObjects() is aware of the process handle.

Tomasz Moń 66f829bc18 win32-utils: Do not share job between Wireshark instances
Creating Job Object named "Local\Wireshark child process cleanup"
results in the job being shared between all Wireshark instances run
within a single session.

When two or more Wireshark instances were running, debug message appeared:
"Could not assign child cleanup process: Access is denied.  (5)"

As the child process was not assigned to a job, it was possible that the
child process was still active even after Wireshark did terminate.

This fixes the issue by creating unnamed job object which is not shared.

Peter Wu 3f9579e3f5 wsutil: use environment variable WIRESHARK_EXTCAP_DIR when possible
The WIRESHARK_EXTCAP_DIR environment variable is currently only used on
Windows, and on UN*X when not running from the build directory. In order
to avoid copying the sampleif.py test utility to the program directory,
let's prioritize the environment variable over the build directory.

Update the outdated comments while at it, the version directory has been
removed long time ago. (The comments are based on the one for plugins.)

This also fixes the test suite on macOS where the extcap subdirectory is
located in the appbundle directory and not the build directory.

Add support for decrypting IEEE 802.11 WPA3-Personal / SAE traffic.

SAE uses AES encryption but a different key derivation function (KDF)
making Wireshark fail to decrypt such captures. Also both KDF and
decryption method is determined based only on EAPOL key description
version. This is not enough to figure out that SAE is being used.

Implement the alternative KDF needed to derive valid PTK. Also
implement a function to parse pairwise + group cipher suites and
auth key management type from RSNE tag. Using this new function
together with a number of new cipher and AKM lookup functions
correct KDF for SAE can be selected.

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.

Guy Harris 20ad0ffbaf Avoid definition collisions for INVALID_SOCKET.
Newer versions of libpcap define it (due to the somewhat infelicitous
API for "active mode" remote capture, which returns a socket); don't
define it ourselves if it's already defined.

Peter Wu ae2a75233c wsutil: fix crash due to corruption of the "small_buffers" array
Gracefully handle repeated calls of ws_buffer_free on the same buffer to
avoid strange crashes in other new users that allocate a "small" buffer.

The first call to ws_buffer_free would store data pointer in the
'small_buffers' array for reuse and set the pointer to NULL. Result:

    (gdb) p cfile.rec.options_buf
    $2 = {
      data = 0x0,
      allocated = 2048,     // Oops, not modified!
      start = 0,
      first_free = 0
    }

All users of Buffer (including ws_buffer_free) however asssume that
'allocated' reflects the actual size of 'data'. If this is not the case
(if ws_buffer_free is called again), then a data pointer (NULL!) will be
stored and the next ws_buffer_init request for a "small buffer" will
result in unexpected behavior (including crashes).

Fix the issue by clearing the 'allocated' field as well. Add assertions
to catch such issues earlier rather than crashing at random users of
these buffers (such as frame_tvbuff).

Craig Jackson 52b7c8929a Z39.50: Implementation of Z39.50 Information Retrieval protocol
NISO Z39.50 is a protocol used by libraries and library vendors for information retrieval and catalog manipulation. It is defined using ASN.1 using BER encoding. It has an assigned TCP port of 210. This is an initial implementation.

Features:
- The Z39.50 standard OIDs are defined.
- The bib-1 attribute set is decoded.
- The bib-1 diagnostics are decoded.
- Some OCTET STRINGs which are nearly always printable ASCII are special-cased.
- The MARC (MAchine Readable Cataloging) format is decoded. Only the MARC21 variant is
  currently handled, but this is one of the most common variants. The most common tags
  are decoded. The MARC dissector is included in the Z39.50 dissector, but the code is
  structured in such away that it could be pulled out.

Todo:
- Add information to the Wiki about Z39.50.

As part of this work, the definition of isdigit_string() was fixed to avoid const complaints.

Peter Wu 0da9763d11 Win32: change DLL search path to accomodate extcap and Npcap
Extcap executables require libwsutil.dll from the program directory.
These were loaded by setting the PATH environment variable, but this
is not thread-safe (and caused sporadic tests failures as a result).
Use SetDllDirectory instead, this also prevents loading DLL files
from arbitrary directories in PATH.

To make this work, the search logic for Npcap has to be modified to
avoid relying on SetDllDirectory. This implies that Npcap cannot be
used on Windows 7 anymore until KB2533623 (July 2011) is applied.

Peter Wu 656cc19fc7 Replace JSON-GLib by custom JSON dumper library
The (optional) JSON-GLib library adds dependencies on GObject, GIO. For
statically linked oss-fuzz builds it also adds libffi and more. To avoid
these dependencies, replace JSON-GLib by some custom code. This allows
`tshark -G elastic-mapping` to be enabled by default without extra deps.

API design goals of the new JSON dumper library:

- Small interface without a lot of abstraction.
- Avoid memory allocations if possible (currently none, but maybe
  json_puts_string will be replaced to improve UTF-8 support).
- Do not implement parsing, this is currently handled by jsmn.

Methods to open/close array/objects and to set members are inspired by
the JsonGlib interface. The interfaces to write values is inspired by
the sharkd code (json_puts_string is also borrowed from that).

The only observed differences in the tshark output:
- JSON-GLib ignores duplicates, json_dumper does not and may produce
  duplicates and currently print two "ip.opt.sec_prot_auth_unassigned".
- JSON-GLib adds a space before a colon (unimportant formatting detail).
- (Not observed, but UTF-8 strings will be wrong like bug 14948.)

A test was added to catch changes in the tshark output. I also fuzzed
json_dumper with libFuzzer + UBSAN/ASAN and fixed an off-by-one error.

Stig Bjørlykke f86d6203a9 extcap: Read stderr on extcap error without an infinite loop
Check if data is available on stderr before doing a blocking read() to
avoid an infinite read loop when having less data than STDERR_BUFFER_SIZE.

Append data instead of overwrite when doing multiple read() to fetch
available data.

This is a regression from g6a949ed155.

Guy Harris a679ae6f79 Use wsetargv.obj, and wmain() rather than main(), on Windows.
Doing so for command-line programs means that the argument list doesn't
ever get converted to the local code page; converting to the local code
page can mangle file names that *can't* be converted to the local code
page.

Furthermore, code that uses setargv.obj rather than wsetargv.obj has
issues in some versions of Windows 10; see bug 15151.

That means that converting the argument list to UTF-8 is a bit simpler -
we don't need to call GetCommandLineW() or CommandLineToArgvW(), we just
loop over the UTF-16LE argument strings in argv[].

While we're at it, note in Wireshark's main() why we discard argv on
Windows (Qt does the same "convert-to-the-local-code-page" stuff); that
means we *do* need to call GetCommandLineW() and CommandLineToArgvW() in
main() (i.e., we duplicate what Qt's WinMain() does, but converting to
UTF-8 rather than to the local code page).

The problem was introduced in c18459e66e

While it might be possible to setup overlapped reads on the pipe handles

code. As a tradeoff, simply keep peeking at the pipes every 100 ms.

Tomasz Moń c18459e66e Fix extcap initialization deadlock
On Windows the code calling extcap worked as follows:
1. Create stdout and stderr pipes with default buffer size
2. Execute extcap redirecting output to the pipes
3. Wait for extcap process to exit
4. Read the data from stdout pipe

This resulted in deadlock when the extcap wrote more data than the pipe
could buffer. This was especially seen with USBPcap as it is quite
normal to have plenty of USB devices connected.

Fix the issue by contantly reading the stdout data and storing it in
GString. To prevent similar deadlock on the stderr, the stderr data is
being constantly monitored as well (and discarded).

Peter Wu d7187e0b1b wsutil: Add Curve25519 ECDH (X25519) using Gcrypt
The WireGuard dissector will need X25519 to enable decryption, add a
Gcrypt implementation that implements the NaCl/Sodium interface.

While inspired by the MPI example in t-cv25519.c, note subtle but
important correctness/interoperability fixes: add a check for infinity
(gcry_mpi_ec_get_affine) and handle short values from gcry_mpi_print.
The last issue is ugly, perhaps the high level API (gcry_pk_decrypt)
should be used instead (which < 2% slower than this MPI implementation).
(Both issues were found through fuzzing.)

As for alternative options, Sodium is superior but would be a new
dependency. For some older performance and usability notes (comparing
crypto_scalarmult_curve25519_base (note "_base") against others), see
https://lists.gnupg.org/pipermail/gcrypt-devel/2018-July/004532.html

Performance comparison on Ubuntu 18.04 (i7-3770) between Sodium 1.0.16
against Gcrypt 1.8.3 and Gcrypt 86e5e06a (git master, future 1.9.x) by
computing 65536 times X25519(1, 8) via crypto_scalarmult_curve25519:

    Sodium (sandy2x):   1.4x faster than ref10
    Sodium (ref10):     1 (baseline)
    Gcrypt (git):       5x slower than ref10, 7x slower than sandy2x
    Gcrypt (1.8.3):     17x ref10, 24x sandy2x (took 65 seconds)

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.
