David Perry 06ed6930dc Carry EPB flags as an option on the packet block
As requested by [this comment][1] on !2859, move `pack_flags` from a
dedicated field in `wtap_rec` to a block option on the packet block in
`wtap_rec.block`.

David Perry 73087d6fb4 Use wtap_blocks for packet comments
Mostly functioning proof of concept for #14329. This work is intended to
allow Wireshark to support multiple packet comments per packet.

Uses and expands upon the `wtap_block` API in `wiretap/wtap_opttypes.h`.
It attaches a `wtap_block` structure to `wtap_rec` in place of its
current `opt_comment` and `packet_verdict` members to hold OPT_COMMENT
and OPT_PKT_VERDICT option values.

Guy Harris eaa4a7022b file-pcapng: redo the way we dissect the data in blocks.
Create a tvbuff that covers the data portion of a block, and use that to
dissect all data in the block, including but not limited to the options.

Catch ReportedBoundsError exceptions and treat them as an indication
that the block length was too short - add an expert info to the block
length item indicating that.

Have separate routines for each block type that dissects the data in
that block type.

While we're at it, check whether the trailing block length is equal to
the  header block length and, if not, report an error in the trailing
block length.

Fix the tests to match.

It's not a valid field type, it's only a hack to support regular

Instead, in the packet-matching code, have a separate syntax tree type
for Perl-compatible regular expressions, and a separate instruction to
load one into a register, and have the "matching" operator for field
types take a GRegex * as the second argument.

João Valverde ba23c3b316 tests: Add argument to trim output to a reasonable size
The output of the "values" tshark glossary has over 1.3M lines. Writing
this to stdout with some test failures is problematic in a number of ways.
Also it's not helpful because stderr is written after stdout (not interleaved)
so there is no output context to the error message. The error/warning
message (from stderr, that triggered the test failure) needs to be
sufficient to provide a good understaning of the test failure.

The output is trimmed to first+last N lines. Some lines are kept as
informational and because it may be useful if the program aborts.

Fixes #17203.

Huang Qiangxiong cd2d35c1d2 Protobuf: fix bugs that parsing complex syntax .proto files
Some .proto files contain complex syntax that does not be described in protobuf official site
(https://developers.google.com/protocol-buffers/docs/reference/proto3-spec).

1. Update 'epan/protobuf_lang_parser.lemon' to:
1) Support complex option names format (EBNF):
    optionName = ( ident | "(" fullIdent ")" ) { "." ( ident | "(" fullIdent ")" ) }
for example, "option (complex_opt2).(grault) = 654;".
2) Make enum body support 'reserved' section (EBNF):
    enumBody = "{" { reserved | option | enumField | emptyStatement } "}"
3) Allow the value of field or enumValue option to be "{ ... }" other than constant:
    enumValueOption = optionName  "=" ( constant | customOptionValue ) ";"
    fieldOption = optionName  "=" ( constant | customOptionValue ) ";"
4) Allow 'group' section missing 'label' (for example, in 'oneof' section).
5) Make 'oneof' section support 'option' and 'group' sections (BNF):
    oneof = "oneof" oneofName "{" { oneofField | option | group | emptyStatement } "}"
6) Ignore unused 'extend' section.
7) Fix the bug of one string being splitted into multi-lines.

2. Update 'epan/protobuf_lang_tree.c' to:
8) Fix the bug of parsing repeated option.

3. Update 'test/suite_dissection.py' to add test case for parsing complex syntax .proto files:
  test/protobuf_lang_files/complex_proto_files/unittest_custom_options.proto
  test/protobuf_lang_files/complex_proto_files/complex_syntax.proto
and dependency files:
  test/protobuf_lang_files/well_know_types/google/protobuf/any.proto

David Perry 27c00ca0e9 Lua: make TvbRange:raw() return a subset #12046 v2
My initial fix caused several double-offset errors in TvbRange_raw()
because I was adjusting for the TvbRange's offset too early in the
process. The proper fix is to only adjust for it in the final call to
get the data.

I also simplified some of the bounds checks to be based on the values in
the TvbRange instead of calling `tvb_captured_length()` and the like,
because its bounds are already checked against the backing Tvb when it's
first taken.

Massively expanded the lua test suite to account for every combination
of passing offsets and lengths to a Tvb or TvbRange and to the
subsequent `:raw()` call.

John Thacker 7654bb260d QT+epan: Set FI_BITS_OFFSET and FI_BITS_SIZE flags on [u]ints and bitmasks
Set the FI_BITS_OFFSET and FI_BITS_SIZE flags appropriately on [u]int[64]
(and thus chars and booleans) where the bitmask is passed in on the
header_field_info. Also set the flags on bitmask items by ORing the bitmasks
from the constituent fields. These flags are only used right now in the
packet diagram.

This makes the packet diagram display those types of fields correctly without
having to use proto_item_set_bits_offset_len(), so long as the bitmask is
correct and the field width of the type matches the octet length. (If it
doesn't match, that's a dissector bug.)

split bit items are a more complicated case and still not handled correctly.

Gerald Combs 30c392f166 Tools+test: Call python3 explicitly.
PEP 394[1] says,

"In cases where the script is expected to be executed outside virtual
 environments, developers will need to be aware of the following
 discrepancies across platforms and installation methods:

  * Older Linux distributions will provide a python command that refers
    to Python 2, and will likely not provide a python2 command.

  * Some newer Linux distributions will provide a python command that
    refers to Python 3.

  * Some Linux distributions will not provide a python command at all by
    default, but will provide a python3 command by default."

Debian has forced the issue by choosing the third option[2]:

"NOTE: Debian testing (bullseye) has removed the "python" package and
 the '/usr/bin/python' symlink due to the deprecation of Python 2."

Switch our shebang from "#!/usr/bin/env python" to "#!/usr/bin/env
python3" in some places. Remove some 2/3 version checks if we know we're
running under Python 3. Remove the "coding: utf-8" in a bunch of places
since that's the default in Python 3.

For WPA security association (SA) entries are created on sucessful
PTK derivation from 4-way handshake frames. WEP though don't use
4-way handshake frames for key derivation and therefore no SA entry

entry and instead form the SA on first successful decryption.

Jeff Widman 8d7ebc732e Fix issues discovered by common python linters
Fix some issues discovered by common python linters including:
* switch `None` comparisons to use `is` rather than `==`. Identity !=
equality, and I've spent 40+ hours before tracking down a subtle bug
caused by exactly this issue. Note that this may introduce a problem if
one of the scripts is depending on this behavior, in which case the
comparison should be changed to `True`/`False` rather than `None`.
* Use `except Exception:` as bare `except:` statements have been
discouraged for years. Ideally for some of these we'd examine if there
were specific exceptions that should be caught, but for now I simply
caught all. Again, this could introduce very subtle behavioral changes
under Python 2, but IIUC, that was all fixed in Python 3, so safe to
move to `except Exception:`.
* Use more idiomatic `if not x in y`--> `if x not in y`
* Use more idiomatic 2 blank lines. I only did this at the beginning,
until I realized how overwhelming this was going to be to apply, then I
stopped.
* Add a TODO where an undefined function name is called, so will fail
whenever that code is run.
* Add more idiomatic spacing around `:`. This is also only partially
cleaned up, as I gave up when I saw how `asn2wrs.py` was clearly
infatuated with the construct.
* Various other small cleanups, removed some trailing whitespace and
improper indentation that wasn't a multiple of 4, etc.

There is still _much_ to do, but I haven't been heavily involved with
this project before, so thought this was a sufficient amount to put up
and see what the feedback is.

Linters that I have enabled which highlighted some of these issues
include:
* `pylint`
* `flake8`
* `pycodestyle`

Mikael Kanstrup 42544c8c44 dot11decrypt: Support decryption using TK user input
Add support for TK user input keys. With this Wireshark can
decrypt packet captures where 4WHS frames are missing and
packet captures with non-supported AKMS, for example
802.11r / Fast BSS Transitioning.

Decryption using user TK works as a backup if the normal
decryption flow does not succeed. Having TK decryption keys
added will affect general IEEE 802.11 dissector performance
as each encrypted packet will be tested with every TK.
Worst case scenario is plenty of TKs where none of them
matches encrypted frames.

On successful user TK decryption an SA is formed based on
parameters used to decrypt the frame. This SA is similar to
what is formed when Wireshark detects and derive keys from
4WHS messages. With the SA entry in place the decryption
performance (success case) should be on par with "normal"
decryption flow.

Aurelien Aptel b8f9448c78 SMB2: try to guess encryption settings when not available
When dissecting a capture made in the middle of an existing encrypted
session we cannot decrypt the traffic because we don't know:

* what SMB dialect and encryption algorithm was picked during the
  session establishment
* which host is the server and which host is the client

Since we know the decrypted payload always starts with a valid header
we use this as an heuristic and try all possible decryption settings.

Aurelien Aptel 95a37ff2fe SMB2: allow users to give decryption keys directly
Previously users could only give a session key via

    uat:smb2_seskey_list:<id>,<seskey>

which was used to generate the decryption keys, as long as the trace
contained the session establishement.

Users have often asked about how to decrypt traffic captured in the
middle of an existing session but this wasn't possible.

This commit extends uat:smb2_seskey_list with 2 extra columns to store
decryption keys so that traffic can be decrypted at any point of the
session.

This has the side effect of changing the current syntax from:

    ... -o uat:smb2_seskey_list:<id>,<seskey>

To:

    ... -o 'uat:smb2_seskey_list:<id>,<seskey>,"",""'

(make sure the quoting is right)

The HTTP/2 protocol multiplexes a single TCP connection into multiple
independent streams. The Follow TCP output can interleave multiple
HTTP/2 streams, making it harder to analyze a single HTTP/2 stream.

Add the ability to select HTTP/2 Streams within a TCP stream.
Internally, the HTTP/2 dissector now stores the known Stream IDs in a
set for every TCP session which allows an amortized O(n) lookup time for
the previous/next/max Stream ID.

[Peter: make the dissector responsible for clamping the HTTP/2 Stream ID
instead of the Qt code, that should permit future optimizations.]

Aurelien Aptel 0db39ae59a smb2: add support for decompression
The latest iteration of Microsoft updates to SMB3 added compression to
the protocol. This commit implements decompressing and dissecting
compressed payloads.

The compression algorithms that can be used are "Plain LZ77",
"LZ77+Huffman" and "LZNT1" which you can read more about in the
[MS-XCA] documentation. This set of algorithm is sometimes referred to
as XPRESS.

This commit reuses the existing uncompression API scheme already in
place with zlib and brotli and adds 3 tvb_uncompress_*() function
implemented in:
* epan/tvbuff_lz77.c
* epan/tvbuff_lz77huff.c
* epan/tvbuff_lznt1.c

A new function wmem_array_try_index() was added to the wmem_array API
to make bound checked reads that fail gracefully. New tests for it
have been added as well.

Since both reads (tvb) and writes (wmem_array) are bound checked the
risk for buffer overruns is drastically reduced. LZ77+Huffman has
decoding tables and special care was taken to bound check these.

Simplified versions of the implementations were succesfully tested
against AFL (American Fuzzy Lop) for ~150 millions executions each.

The SMB2/3 dissector was changed to deal with the new transform header
for compressed packets (new protocol_id value) and READ request
flags (COMPRESSED). Badly compressed or encrypted packets are now
reported as such, and the decryption test suite was changed to reflect
that.

This commit also adds a test capture with 1 packet compressed with
each algorithm as returned by Windows Server 2019, along with 3
matching tests in test/suite_dissection.py

to be listed under "Flags", this is not correct. The Fragmentation
Offset is a separate field according to the RFC. This change corrects

The outputs of -T ek and -G elastic-mapping don't match. To be effective
the fields in the mapping report and the fields in the traffic output must
be the same.

2 issues have been fixed. The elastic-mapping requires the parent protocol
to be prepended to the field to match the traffic output. The field "dns.a"
has been changed to "dns_dns_a".
The traffic output prints some fields with a leading "text_". This happens
for some fields that have been created under a text only field. One example
is "dns.a", that was printed as "text_dns_a". This has been fixed by accessing
the parent hfinfo resulting in "dns_dns_a" as other fields for the dns
protocol.

Peter Wu b641febb1e TLS: Implement reassembly for Handshake messages
Lack of handshake reassembly caused Certificate handshake messages to be
reported as "Encrypted Handshake Messages" and broke decryption in some
cases. Fix this by properly tracking handshake fragments and delay
dissection until all fragments are available.

Now when a fragmented Handshake message is found:

* The first fragment will have "(fragmented)" appended to the record
  tree item as well as the "Handshake Protocol" item.
* "Reassembled Handshake Message in frame: X" is added for fragments.
* The last reassembled handshake message will be displayed together with
  a fragment list.

Note: Previously, handshake records with a message length larger than
the available data was assumed to be encrypted. This restriction had to
be lifted, but can now cause false positives (reporting encrypted data
as unencrypted handshake fragments).

The provided capture is not minimal but should be comprehensive as it is
generated with randomly sized TLS record and TCP segment lengths using
`./tls-handshake-fragments.py hs-frag.pcap --seed=1337 --count=100` and
https://git.lekensteyn.nl/peter/wireshark-notes/tree/crafted-pkt/tls-handshake-fragments.py

This also fixes the test suite on macOS where the extcap subdirectory is

Peter Wu cbe7f26a86 DTLS: add DSB support, use the key log file from the TLS dissector
The DTLS and TLS dissectors already share code for parsing the key log
file contents but the actual key material was stored separately. As
implementations (like GnuTLS) write the TLS and DTLS secrets to the same
file (specified by the SSLKEYLOGFILE environment variable), it seems
reasonable to combine them.

This also enables use of the pcapng Decryption Secrets Block for
decryption of DTLS traces. The dtls.keylog_file preference has become
obsolete and can no longer be used (this was not tested anyway).

A new test was added based on dtls12-aes128ccm8.pcap, the master secret
was extracted using the tls.debug_file preference.

Peter Wu 52a6671439 wiretap: add read/write support for Decryption Secrets Block (DSB)
Support reading and writing pcapng files with DSBs. A DSB may occur
multiple times but should appear before packets that need those
decryption secrets (so it cannot be moved to the end like NRB). The TLS
dissector will be updated in the future to make use of these secrets.
pcapng spec update: https://github.com/pcapng/pcapng/pull/54

As DSBs may be interleaved with packets, do not even try to read it in
pcapng_open (as is done for IDBs). Instead process them during the
sequential read, appending them to the 'wtap::dsbs' array.

Writing is more complicated, secrets may initially not be available when
'wtap_dumper' is created. As they may become available in 'wtap::dsbs'
as more packets are read, allow 'wtap_dumper::dsbs_growing' to reference
this array. This saves every user from checking/dumping DSBs.

If the wtap user needs to insert extra DSBs (while preserving existing
DSBs), they can set the 'wtap_dumper::dsbs_initial' field.

The test file was creating using a patched editcap (future patch) and
combined using mergecap (which required a change to preserve the DSBs).

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.

Peter Wu 3ab521118a test: convert capture tests to use fixtures, fix tests without dumpcap
Add a new --capture-interface option to pytest, similar to test.py. It
will grab some Ethernet interface on Windows. An empty value overrides
this and disables capture tests. Remove the test.py --enable-capture
option since that is implied by the --capture-interface option.

Port the `test.py --program-path` option to pytest and additionally make
the pytest look in the current working directory if neither WS_BIN_PATH
nor --program-path are specified. Drop config.setProgramPath, this
allows tests to be run even if not all binaries are available.

With all capture tests converted to fixtures, it is now possible to run
tests when Wireshark is not built with libpcap as tests that depend on
cmd_dumpcap (or capture_interface) will be skipped.

Peter Wu 4f61d77293 test: convert some more tests to use fixtures
Continue the conversion from use of globals (the config module) to
fixtures. If a program (like wmem_test or tshark) is unavailable, it
will be skipped now rather than failing the test.

The general conversion pattern is:
- Decorate each class with `@fixtures.uses_fixtures` and (for tests that
  run tshark) `@fixtures.mark_usefixtures('test_env')`.
- Convert all `config.cmd_*` to `cmd_*` and add an argument.
- Convert all `config.*_dir` to `dirs.*_dir` and add an argument.
- Convert users of `os.path.join(dirs.capture_file, ...)` to use a new
  'capture_file' fixture to reduce boilerplate code. Inline variables if
  possible (this conversion was done in an automated way using regexes).

Some other changes: tests that do not require a test environment (like
wmem_test) will use 'base_env' which avoids copying config files,
`env=config.test_env` got removed since this is the default. Some test
classes in suite_clopts were combined. Removed unused imports.

Peter Wu 961f1388e4 wiretap: fix truncated reads while reading compressed file formats
A lot of file dissectors (pcapng, json, etc.) assumed that the packet
size is equal to the file size. This is not true if the file was
compressed and could result in silently truncating reads or failing to
open a file (if the compressed file is larger than the actual data).

Observe that a lot of file dissectors are simply copies of each other.
Move the fixed implementation to wtap.c and reuse the methods everywhere
else. While at it, avoid an unnecessary large allocation/read in
ruby_marshal.

Peter Wu 54d7e96a72 test: make it possible to use pytest-style test fixtures
Currently all binaries must be available or no tests will be executed.
This is inconvenient if you just want to test a single binary (e.g.
text2pcap) without having to build epan. The problem is essentially that
tests lack dependency annotations.

To solve this problem, add the required dependencies as parameters to
each test (so-called 'fixtures' in pytest). Skip a test if a binary
(such as tshark) is unavailable. As a demonstration, suite_dissection.py
is converted. Over time, tests should no longer depend on config.py due
to explicit dependencies fixtures (listed in fixtures_ws.py).

Since the unittest module does not support such dependency injections,
create a small glue for use with pytest and an (incomplete) emulation
layer for use with test.py.

Tested with pytest 3.8.2 + Python 3.7.0 and pytest 3.0.3 + Python 3.4.3.
Python 2.7 is not supported and will fail. Test commands:

    ~/wireshark/test/test.py -p ~/build/run
    WS_BIN_PATH=~/build/run pytest ~/wireshark/test -ra

Peter Wu 22cf80d30d text2pcap: gracefully handle hexdump without trailing LF
When copying hexdumps, the newline might be missing which would result
in a capture file missing one byte in its packet. Adjust the grammar to
recognize the two trailing hexadecimal characters as a "byte".

This is safe because Flex picks the rule that matches the longest input
string. So given "01 ", it will always match all three characters. If
something like "01x" is given, then the "text" rule will be matched (as
before). Only if no more characters are available (such as at the end of
a file), then the rule will match two hexdigits.

Remove the unnecessary hexdigit rule while at it.

Peter Wu 62874e3778 TLS13: add final tests for RFC 8446
Add TLS 1.3 tests that verify decryption of handshake, application and
early data. Add another test that shows that early data is properly
skipped. This completes TLS 1.3 (RFC 8446) decryption support.

The trace was created using boringssl c4131a4a23a1.

Peter Wu e754937251 WireGuard: implement decryption with PSKs
This imposes an additional requirement on the key log file, PSKs are
only linked to the most recently seen ephemeral key. This means that the
key log might contain duplicate PSK lines, but at least the dissector
won't have to try all keys and thereby save CPU time.

Peter Wu c30b9fc891 WireGuard: add keylog for initiation decryption with ephemeral keys
As UATs are currently unable to receive keys dynamically without manual
user interaction followed by rescanning of the pcap, add a mechanism
like ssl.keylog_file. Such keys can be extracted using the tools from
contrib/examples/extract-handshakes/ in the WireGuard source tree.

Now decryption of Initiation messages is also possible when keys
(Epriv_i) are captured from the initiator side.

Peter Wu 9ca8a9f87c test: do not silently ignore feature detection failures
When ASAN memleak detection is enabled, any memory leak would result in
an exception and subsequently all features are marked as missing.
With the default profile, any Lua plugin or certain configurations could
cause a memory leak. To avoid such interference, set the configuration
path to a dummy location and warn whenever an error happens nonetheless.

Do not call setProgramPath() immediately, there is no "tshark" binary in
the current working directory anymore. Rely on test.py to set the path.

Peter Wu 0ce2cdda8b Tests: add minimal pytest support
pytest is a powerful test framework. The initial motivation is to have
much better detailed reporting when a test fails, see for example
https://docs.pytest.org/en/latest/

Additionally, it has full parallelization support at the test level (via
the pytest-xdist plugin) instead of being limited to the suite level
(which currently has to be hard-coded via CMakeLists.txt).

Usage with the build dir in /tmp/wsbuild and src dir in /tmp/wireshark:

    export WS_BIN_PATH=/tmp/wsbuild/run
    pytest /tmp/wireshark/tests

For parallelization support and verbose printing:

    pip install pytest-xdist
    pytest -nauto -v /tmp/wireshark/tests

To limit yourself to a case based on a pattern:

    pytest -nauto -v /tmp/wireshark/tests -k test_unit_ctest_coverage

Tested on Arch Linux with Python 3.6.5, pytest-3.6.2, xdist-1.22.2.
pytest -n8 finished in 82 seconds while ctest -j8 required 87 seconds.

Peter Wu ca42331437 tcp: add support for reassembling out-of-order segments
Currently out-of-order segments will result in cutting a stream into
two pieces while the out-of-order segment itself is ignored. For
example, a stream of segments "ABDCE" is interpreted as "AB", "DE" with
"C" ignored. This behavior breaks TLS decryption or prevent application
layer PDUs (such as HTTP requests/responses) from being reconstructed.
To fix this, buffer segments when a gap is detected.

The proposed approach extends the "multi-segment PDU" (MSP) mechanism
which is normally used for linking multiple, sequential TCP segments
into a single PDU. When a gap is detected between segments, it is
assumed that the segments within this gap are out-of-order and will be
received (or retransmitted) later.

The current implementation has a limitation though, if multiple gaps
exist, then the subdissector will only be called when all gaps are
filled (the subdissector will receive segments later than necessary).
For example with "ACEBD", "ABC" can already be processed after "B" is
received (with "E" still buffered), but due to how MSP are extended, it
must receive "D" too before it reassembles "ABCDE". In practice this
could mean that the request/response times between HTTP requests and
responses are slightly off, but at least the stream is correct now.
(These limitations are documented in the User's Guide.)

As the feature fails at least the 802.11 decryption test where packets
are missing (instead of OoO), hide this feature behind a preference.

Tested with captures containing out-of-order TCP segments from the
linked bug reports, comparing the effect of toggling the preference on
the summary output of tshark, the verbose output (-V) and the two-pass
output (-2 or -2V). Captures marked with "ok" just needed "simple"
out-of-order handling. Captures marked with "ok2" additionally required
the reassembly API change to set the correct reassembled length.

This change does "regress" on bug 10289 though when the preference is
enabled as retransmitted single-segment PDUs are now passed to
subdissectors. I added a TODO comment for this unrelated cosmetic issue.
