The current implementation misses an edge case, where bit 15 of the FC Field
must be zeroed in case a QoS Control field is present (IEEE 802.11 12.5.3.3.3),
which results in a wrong AAD and subsequently in the failure of the packet
decryption for QoS Data Frame carrying a HT Control Field (indicated by bit
15 set to 1).
In addition the field 14 must be 1, which is ensured explicitly (the author is
not sure if the code is reachable by frames which do not have bit 14 set to
one).
Call existing MJPEG and H.264 dissectors for those subtypes,
and remove duplicate fields. Use common true_false_string.
Warn about invalid length, and only process the payload length
show in the payload field, allowing for Ethernet FCS autodetection,
among other things. Register the MJPEG dissector by name so
that AVTP CVF can call it. Add some value string entries to the
MJPEG dissector.
When the format value is reserved, ignore the subtype field
and add expert info and show the payload as data. (IEEE 1722-2016
8.3.2) Fix#12490
Apple provides a status page for various developer services at
https://developer.apple.com/system-status/, including the status of the
Developer ID Notary Service. Show the URL notarization fails so that
troubleshooting is easier.
Pass $<TARGET_FILE_DIR:wmem_test> to test.py, which should be the path
for all of our built executables, instead of ...:tshark, which is the
path for *some* of our built executables on macOS.
- Handle 'Category' field under 'Encapsulated Frame' field inside 1905 Encap DPP TLVs
It violates the tvb_composite API to create composite TVBs if
they're not going to have at least one TVB put in them. Prevent
dissector bug failed assertions in the case of packets incorrectly
identified as DVB Baseband frames carrying TS by the heuristic
dissector.
A few of them just needed scratch memory, so allocate and free it
manually after doing any exception-raising checks.
A few others were returning memory, and needed conversion to accept a
wmem scope argument.
When cross-compiling wireshark the lemon tool should be built
using the host machine compiler to be run on the host. Before
cmake this was done via autotools CC_FOR_BUILD but cmake only
supports one compiler toolchain per build and requires some
workarounds like running cmake twice using separately defined
toolchains.
This gets ugly and complicated fast when considering multiple
toolchains, especially for a simple tool like lemon, so just
allow builds to override the C compiler and wipe the cflags.
This way systems like Gentoo/ChromeOS/Yocto with a properly
setup cross-compile environment can just point to the native
BUILD_CC or similar while minimizing complexity.
Wireshark fails to build when cross-compiling on Gentoo/ChromeOS
systems because the lemon command is not properly specified or
included in PATH, failing with:
/bin/sh: lemon: command not found
The relevant excerpt from build.ninja is:
COMMAND = cd ..._build/plugins/epan/mate && lemon -T.../tools/lemon/lempar.c
-d. .../plugins/epan/mate/mate_grammar.lemon
By specifying the full path to "lemon" we ensure it is
always searched and found in the correct location.
Handle multiple PDUs per TCP segment or UDP datagram. Add
preference for handling PDUs that span multiple TCP segments.
Fix nested depth handling so as not to clear COL_INFO in the
second PDU of a segment (and also make dissect_knxip have the
standard signature.) Fix#17545.
On the first packet of the conversation, the MPA layer is
dissected correctly followed by the DDP, RDMAP, RPC-over-RDMA,
RPC and NFS layers. The MPA layer sets the TCP conversation as
MPA protocol but when it dissects the RPC layer it also sets
the TCP conversation as RPC protocol thus overwriting the previous
protocol.
Added new port type PT_IWARP_MPA so that when the RPC layer
is dissected it does not overwrite the default protocol for
the TCP conversation which has already been set to MPA.
Fixes#15869.
This patch adds support for the ISO 10681-2 protocol, which is similar
to the ISO 15765-2 protocol (see packet-iso15765.c).
This patch also add support for registering combined FlexRay IDs to
register the new dissector.
Use compute_options_size() to get the total size of all the options, and
use write_options() to write out the options for those blocks, as we do
for other blocks.
Get rid of wtap_block_option_get_value_size() and
wtap_block_get_options_size_padded(); they're no longer needed, and
their notion of an option's "size" is "size in a pcapng file", so that
doesn't belong in code that's intended to support all file types.
Have a routine to read the Sniffer record header, and call that in
ngsniffer_read() and ngsniffer_seek_read(). Only call
ngsniffer_process_record() for frame records that we understand, so that
we only allocate a block for those rather than for records we don't
understand or for EOF records, potentially leaking them.
This patch adds support to DoIP and ISO15765 to pass the diagnostic
address or addresses to UDS. UDS takes the relevant address into account
for the data identifier and routine identifier name resolution.
Wireshark/tshark may be built without Lua support. This patch adds an
error message if the user specifies the `-X lua_script` command-line
argument to a program built without Lua support, so the user is not left
wondering why their script isn't working.
Use correct offset for P1 and P2 when showing channel operation
and channel number.
According to TS 102 221 V14.2.0 the Open channel operation is using
P2 for channel, and let UICC assign when this is 0. Show P3 as Le.
Make P3 optional because it's not present in at least Close channel
operation.
Change text in Info column to avoid "Channel Channel: x".
Add git dissection test cases to existing testing suite for: finding git
packets, finding the Git Protocol version, finding the right amount of
Flush and Delimiter packets, not finding Malformed packets.
Part of #17093
Without that, you could add a comment to a record in a file format the
reading code for which doesn't allocate blocks, but the comment doesn't
get saved, as there's no block in which to save the comment option.
This simplifies some code paths, as we're either using the record's
modified block or we're using the block as read from the file, there's
no third possibility.
If we attempt to read a record, and we get an error, and a block was
allocated for the record, unreference it, so the individual file readers
don't have to worry about it.
Update channel to include index to clear up possible confusion if this
is RF channel, or channel index.
