Remove unneeded row number in capture file. The packet list is
the only object that should know the correct number, propagating
it further only complicates things. At the same time, rework
cf_select_packet to select the packet based on frame_data not on
the row (which can be unreliable).
Remove duplicate functionality for jumping to packet and
remove unused function to move to the end. Furthermore
move the code for redraws of visible packets directly
into the calling code
Setting sorting enabled/disabled resorts the list. If this happens
too often, sometimes it can lead to the physical view models
not present anymore and therefore crashing.

Port the script that creates init.lua to Python3. The generated init.lua
removes one newline and adds another, otherwise the output is identical
to the Perl version.
Ping #18152.
Port the script that creates taps_wslua.c and taps.txt to Python3. The
generated taps_wslua.c has one less newline, otherwise the output is
identical to the Perl version. Make the "taps" configuration file an
ConfigParser / .ini file.

The progress frame animation is so slow, that it might not show
up on certain setups. Reduce the initial speed and duration for
the animation, which also speeds up calculations as well as dissection
as less animation has to be rendered/calculated
This code adds more robust handling of smaller issues with PTP messages,
like a missing 2-step flag of a not quite correct implementation of
802.1AS and improves 1-step support.
Changes:
- Handle 1-step syncs in analysis.
- Handle missing 2-step flag on pDelay more robust and warn in analysis.
- Handle missing F'up TLV in 802.1AS Sync more robust and warn.
Reject the previous reserved and unassigned TURN channels and
STUN methods restricted by RFC 5764 and RFC 7983 to allow
multiplexing of STUN with DTLS-SRTP (and ZRTP) on the same
addresses and ports. (As an exception, allow the special MS
Multiplex TURN channel value.) Earlier versions of the specs
had these as unassigned (or did not support TURN Channels), and
no implementation has used them.
This prevents the STUN dissector from claiming RTP packets
going to the same port as set for STUN by Decode As, and should
allow us to set the STUN dissector as the dissector for a conversation
on UDP if we see any STUN message, not just a TURN message type.
- Declare a separate type for the IPv6 TLV MAC address, otherwise its
filter key is `ieee1905.ipv4_type.mac_addres` instead of the expected
`ieee1905.ipv6_type.mac_addres` one which is confusing
- Fix label for `hf_ieee1905_ipv6_type_count` to read "IPv6 address count"
instead of the wrong "IPv4 address count"
- Parse the IPv6 link local address which appears between the EUI-48 and
the IPv6 address count in IPv6 type TLVs, without that, valid IPv6 TLVs
are wrongly parsed and reported as malformed

MS-IMPLEMENTATION-VERSION is not a duplicate of MS-VERSION, and
has a different interpretation. MS-VERSION is the version number
of MS-TURN, its values described in 2.2.2.17 of its spec, and
MS-IMPLEMENTATION-VERSION is the version of MS-ICE2, its values
described in section 3.1.5.2 of its spec.
The latter indicates whether the STUN message format must be that of
Internet-Draft behave-rfc3489bis-02 (that is, roughly the final
form of classic STUN, also used in MS-TURN) or whether that of
RFC 5389 is also supported.
HTTP chunked transfer encoding can have lots of chunks, and calling
the data dissector for each individual chunk adds a large number of
layers to the frame and doesn't really make sense. (As opposed to
calling the data dissector on the reassembled data if we can't handle
the content type, which does make sense.) In particular, this can
cause a failed assertion by adding more layers than
PINFO_LAYER_MAX_RECURSION_DEPTH.
Just add each data chunk as a FT_BYTES item. Fix#18130.
This adds support for using the layers filter
with field references.
Before:
$ dftest 'ip.src != ${ip.src#2}'
dftest: invalid character in macro name
After:
$ dftest 'ip.src != ${ip.src#2}'
Filter: ip.src != ${ip.src#2}
Syntax tree:
0 TEST_ALL_NE:
1 FIELD(ip.src <FT_IPv4>)
1 REFERENCE(ip.src#[2:1] <FT_IPv4>)
Instructions:
00000 READ_TREE ip.src <FT_IPv4> -> reg#0
00001 IF_FALSE_GOTO 5
00002 READ_REFERENCE_R ${ip.src <FT_IPv4>} #[2:1] -> reg#1
00003 IF_FALSE_GOTO 5
00004 ALL_NE reg#0 != reg#1
00005 RETURN
This requires adding another level of complexity to references.
When loading references we need to copy the 'proto_layer_num'
and add the logic to filter on that.
The "layer" sttype is removed and replace by a new
field sttype with support for a range. This is a nice
cleanup for the semantic check and general simplification.
The grammar is better too with this design.
Range sttype is renamed to slice for clarity.
Use "True" or "TRUE" instead of "true" and remove case insensivity.
Same for false. This should serve to differentiate booleans a bit
more from protocol names, which should be using lower-case.
This change fixes a segmentation fault core dump in tshark/Wireshark
when loading a pcapng file that contains the packet verdict option.
This problem got introduced in the commit mentioned below.
Fixes: 030b06ba3c ("pcapng: write packet and Netflix custom blocks the same as other blocks.")

This dissector is for the control messages of the GRE bonding protocol by
Huawei. These messages are encapsulated in GRE and can appear on both/all
bonding links.
During development, I made heavy use of traffic for Deutsche Telekom Hybrid
service. There fore, it also supports the first version which did not have an
IEEE assigned ethertype.
By adding signal aggregation the time to change profiles changed
dramatically. This is due to unregistering header fields being a very
slow operation and for aggregation each signal line did not lead to 2
but to 5 hfs.
Unregistering header fields for 150k signal example config (debug build):
- 3.6: 50s
- 3.7: 592s (9:52!!!)
This patch brings the time back to 50s, if no aggregation is configured.
Use host byte-order with AT_NUMERIC to make it more generic
and practical.
Change openSAFETY to pass addresses in host byte-order (the
previous code assumed they were in little-endian).
Plus a few cleanups.
