When there is no do_dissection cf is missing some variables
for cf_close() call. Therefore we have to set them explicitly.
Fixes: wireshark/wireshark#17021
This reverts commit 5df2925434.
The problem only showed up in tfshark.c, and was caused by tfshark.c
using stuff from ui/urls.h but not *including* ui/urls.h.
If you use it, GCC 9.3.0 seems to think there's a missing parenthesis
somewhere, just as the version of clang++ in my version of Xcode does,
even though other versions of GCC don't. I'm clearly missing something
obscure about C here; I give up.
Instead of grabbing the set of IDBs found at open time, have a loop
using wtap_get_next_interface_description() to read all unread IDBs run
after opening the input file, after reading a packet from the input
file, and after getting an EOF on the input file.
Add a routine wtap_uses_interface_ids() to check whether the file type
and subtype for a dump file uses interface IDs and requires IDBs. If
so, in the aforementioned loop, add the IDBs to the dump stream.
Add a routine wtap_dump_add_idb() to add IDBs to a dump stream. Have it
call a file-format-specific routine to add the IDBs; the only file type
that supports it is pcapng, and it 1) writes out the IDB and 2) adds it
to the set of IDBs for the stream.
Add a wtap_dump_params_init_no_idbs() routine that prevents the IDBs
from the input file from being used to initialize the output file; use
it in cases where we're using the aforementioned loop to copy over IDBs.
Don't require any IDBs to be present when opening a pcapng file for
writing; 1) the simplest pcapng file has just an SHB in it, 2) that
requirement causes dumps that don't provide IDBs at open time to fail,
and 3) the real issue is that we don't want packets with an interface ID
not corresponding to a known IDB, and we already have a check for that.
(There are some hacks here; eventually, when everything processes the
IDBs in such a loop, we may be able to get rid of the "two favors of
dump parameter initialization" hack.)
Fixes#15844.
Addresses the same issue in #15502, but there are other issues there
that also need to be addressed.
In addition, the merge code also needs to be changed to handle this.
Add ui/urls.h to define some URLs on various of our websites. Use the
GitLab URL for the wiki. Add a macro to generate wiki URLs.
Update wiki URLs in comments etc.
Use the #defined URL for the docs page in
WelcomePage::on_helpLabel_clicked; that removes the last user of
topic_online_url(), so get rid of it and swallow it up into
topic_action_url().
Add extcap_ensure_all_interfaces_loaded, which calls
extcap_load_interface_list if our interface list is empty. Call it in
each of our public functions that require a valid interface list.
Clean up the extcap API documentation and note which routines initialize
the interface list.
In tshark, don't unconditionally call extcap_register_preferences and
instead rely on lazy loading.

In each of our executables we were calling "setlocale(LC_ALL, "")" at

system code page. Unless the code page was 65001 (UTF-8), this was a lie.
We write UTF-8 to stdout and stderr, so call "setlocale(LC_ALL, ".UTF-8)"
at startup on Windows. This lets the CRT translate our output correctly
in more cases.
Clarify and expand the OUTPUT section in the tshark man page.

EPIPE almost certainly means "the next program after us in the pipeline
exited before we were finished writing", so this isn't a real error, it
just means we're done. (We don't get SIGPIPE because libwireshark
ignores SIGPIPE to avoid getting killed if writing to the MaxMind
process gets SIGPIPE because that process died.)
Presumably either that program exited deliberately (for example, "head
-N" read N lines and printed them), in which case there's no error to
report, or it terminated due to an error or a signal, in which case
*that's* the error and that error has been reported.
(We don't do that for EINVAL, as that's presumably a real error. It
shows up on Windows in bug 16192, but what we probably want to do there
is to, on Windows, use _doserrno, check for the equivalent Windows
errors, and, for the default case, convert _doserrno to the appropriate
string, using Windows APIs, and report *that* string; the MS C library
converts a whole bunch of Windows errors to EINVAL, thus losing
information and making it harder to determine what the real error is.
Therefore, I'm just marking this with Ping-Bug, as it's only fixing the
problem on UN*Xes.)

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.

This:
1) means that we don't have to flag the compression argument with a
comment to indicate what it means (FALSE doesn't obviously say "not
compressed", WTAP_UNCOMPRESSED does);
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).

It means "snapshot length unknown".
For most file formats, the snapshot length isn't recorded (even for
formats that support slicing - all they record is the on-the-network
length, and length after slicing, for each packet), so it's ignored in
the dumper.
The one exception is pcap, which records it in the file header; if it's
unknown, the pcap-writing code picks the maximum supported snapshot
length for the file's link-layer header type.

Four variants of wtap_dump_open_ng exists, each of them take the same
three parameters for the SHB, IDB and NRB blocks that has to be written
before packets are even written. Similarly, a lot of tools always create
these arguments based on an existing capture file session (wth).
Address the former duplication by creating a new data structure to hold
the arguments. Address the second issue by creating new helper functions
to initialize the parameters based on a wth. This refactoring should
make it easier to add the new Decryption Secrets Block (DSB).

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).

Currently, the Elasticsearch output exports the packet details and,
if -x is specified, the raw hex data.
This change adds the option of exporting the packet summary as well.
The default stays the same (packet details only), but now the existing
-P switch turns on printing of the packet summary. It also turns off
printing packet details, which can be turned back on with -V to print
both, and combined with -x to print all three: summary, details and
raw hex.
The packet summary is especially useful when exploring and visualizing
the data in Kibana, e.g. by displaying the summary "Info" field/column
in a table, as in the Wireshark GUI.

Depending on how packetlist columns are arranged certain columns may have a
Unicode arrow character inserted between it and the subsequent column to
indicate source vs destination column directionality when displayed in
tshark. Currently any inserted Unicode arrow characters are
unconditionally prefaced with an ASCII SPACE character.
Tshark's `-T tabs` option causes the various packetlist columns to be
delimited with ASCII TAB characters. The unconditional use of the SPACE
character before any inserted Unicode arrows makes it difficult to directly
compare a -T tabs report of column N values to column N+1 values without
dealing with the SPACE/Unicode Arrow suffix appended to all of the column
N values.
The inserted Unicode directionality arrows are effectively another
packetlist column of data that should be delimited like all other columns.
This patch ensures that any Unicode directionality arrows inserted between
packet list columns are delimited on both sides of the arrows with the
selected delimiter character.

command line options to dumpcap, wireshark and tshark:
--list-time-stamp-types
List time stamp types supported for the interface
--time-stamp-type <type>
Change the interface's timestamp method
Name choice mimics those used by tcpdump(1), which already supports this
feature. However, unlike tcpdump, we provide both options unconditionally.
If Wireshark was configured without pcap_set_tstamp_type being available,
--list-time-stamp-types reports an empty list.

Adds the --no-duplicate-keys option to tshark. If -T json is specified,
this option can be specified in order to transform the duplicate keys
produced by -T json into single keys with as value a json array of all
separate values.
Specifying --no-duplicate-keys changes the function which groups node
children that is passed to write_json_proto_tree. Instead of a function
that puts each node in a separate group (proto_node_group_children_by_unique)
a function is passed that groups children that have the same json key
together (proto_node_group_children_by_json_key). This will lead to
some groups having multiple values. Groups with multiple values are
written to the output as a json array. This includes normal json keys
but also keys with the "_raw" and "_tree" suffix.
If --no-duplicate-keys is specified with an option other than "-T json"
or "-T jsonraw" or without -T an error is shown and tshark will exit.
"Export Packet Dissections -> As JSON" in the GUI is hardcoded to use
the duplicated keys format.
Fixes one regression in the output where a filtered json key (-j) with
both a value and children would not have the "_tree" suffix added to the
json key containing the children.
Includes a little code cleanup (removes one instance of code
duplication and simplifies a while loop).
Fixes a memory leak (I thought this fix was already included in the
previous refactor patch but something must have gone wrong when updating
the patch so I'm including it again in this patch).
