The name of the block, in the pcapng specification is the systemd
Journal Export Block; add "export" after "journal" in various
variable/enum/define names.
A domain filter can be given in the environment variable
'WS_LOG_DOMAINS' or in a command-line options "--log-domains".
The filter is specified as a comma separated case insensitive list,
for example:
./tshark --log-domains=main,capture
Domain data type switches from an enum to a string. There is no
constaint on adding new domains, neither in code or at runtime.
The string format is arbitrary, only positive matches will produce
output.
Experience has shown that:
1. The current logging methods are not very reliable or practical.
A logging bitmask makes little sense as the user-facing interface (who
would want debug but not crtical messages for example?); it's
computer-friendly and user-unfriendly. More importantly the console
log level preference is initialized too late in the startup process
to be used for the logging subsystem and that fact raises a number
of annoying and hard-to-fix usability issues.
2. Coding around G_MESSAGES_DEBUG to comply with our log level mask
and not clobber the user's settings or not create unexpected log misses
is unworkable and generally follows the principle of most surprise.
The fact that G_MESSAGES_DEBUG="all" can leak to other programs using
GLib is also annoying.
3. The non-structured GLib logging API is very opinionated and lacks
configurability beyond replacing the log handler.
4. Windows GUI has some special code to attach to a console,
but it would be nice to abstract away the rest under a single
interface.
5. Using this logger seems to be noticeably faster.
Deprecate the console log level preference and extend our API to
implement a log handler in wsutil/wslog.h to provide easy-to-use,
flexible and dependable logging during all execution phases.
Log levels have a hierarchy, from most verbose to least verbose
(debug to error). When a given level is set everything above that
is also enabled.
The log level can be set with an environment variable or a command
line option (parsed as soon as possible but still later than the
environment). The default log level is "message".
Dissector logging is not included because it is not clear what log
domain they should use. An explosion to thousands of domains is
not desirable and putting everything in a single domain is probably
too coarse and noisy. For now I think it makes sense to let them do
their own thing using g_log_default_handler() and continue using the
G_MESSAGES_DEBUG mechanism with specific domains for each individual
dissector.
In the future a mechanism may be added to selectively enable these
domains at runtime while trying to avoid the problems introduced
by G_MESSAGES_DEBUG.
Calling cmake with -DENABLE_VLD=ON when building with Visual Studio,
results in debug configuration being linked to Visual Leak Detector.
By default, Visual Leak Detector outputs the leak summary to Visual
Studio debug window. When ENABLE_VLD is active, VLD is linked to all
wireshark libraries and executables.
Have routines to report capture-file errors, using libwireshark error
codes and strings, that call through a pointer, so they can pop up
dialogs in GUI apps, print a message to the standard error on
command-line apps, and possibly do something different on server
programs.
Have init_report_message() take a pointer to structure containing those
function pointers, rather than the function pointers themselves, as
arguments.
Make other API changes to make that work.
Register the pcap and pcapng file types/subtypes rather than hardwiring
them into the table.
Call the registration routines for them directly, rather than through a
generated table; they're always supposed to be there, as some code in
Wireshark either writes only one of those formats or defaults to writing
one of those formats. Don't run their source code through the
registration-routine-finder script.
Have the file type/subtype codes for them be directly exported to the
libwiretap core, and provide routines to return each of them, to be used
by the aforementioned code.
When reporting errors with cfile_write_failure_message(), use
wtap_dump_file_type_subtype() to get the file type/subtype value for the
wtap_dumper to which we're writing, rather than hardcoding it.
Have the "export PDU" code capable of supporting arbitrary file
types/subtypes, although we currently only use pcapng.
Get rid of declarations of now-static can_write_encap and
dump_open routines in various headers.
Instead of a "supports name resolution" Boolean and bitflags for types of
comments supported, provide a list of block types that the file
type/subtype supports, with each block type having a list of options
supported. Indicate whether "supported" means "one instance" or
"multiple instances".
"Supports" doesn't just mean "can be written", it also means "could be
read".
Rename WTAP_BLOCK_IF_DESCRIPTION to WTAP_BLOCK_IF_ID_AND_INFO, to
indicate that it provides, in addition to information about the
interface, an ID (implicitly, in pcapng files, by its ordinal number)
that is associated with every packet in the file. Emphasize that in
comments - just because your capture file format can list the interfaces
on which a capture was done, that doesn't mean it supports this; it
doesn't do so if the file doesn't indicate, for every packet, on which
of those interfaces it was captured (I'm looking at *you*, Microsoft
Network Monitor...).
Use APIs to query that information to do what the "does this file
type/subtype support name resolution information", "does this file
type/subtype support all of these comment types", and "does this file
type/subtype support - and require - interface IDs" APIs did.
Provide backwards compatibility for Lua.
This allows us to eliminate the WTAP_FILE_TYPE_SUBTYPE_ values for IBM's
iptrace; do so.
Remove NG from the names - it adds nothing.
Don't use the abbreviations for pcapng block names, spell out what the
block does (e.g. "WTAP_BLOCK_DECRYPTION_SECRETS" rather than
"WTAP_BLOCK_DSB"), to make it more obvious what the block does.
Spell out some other abbreviations.
Add WTAP_BLOCK_PACKET for future use for packet blocks; there's no need
to distinguish between the Enhanced Packet Block, the Simple Packet
Block, and the deprecated Packet Block here.
It corresponds to LINKTYPE_ETW in pcap and pcapng files; the structures
in the record format come from the Event Tracing for Windows (ETW) API
rather than directly from Event Trace Log files.
While we're at it, explain what extcap/etl does.
New link type DLT_ETW is added for write and read Event Trace on Windows.
This change updates MBIM dissector to decode a MBIM message from
a DLT_ETW packet.
sshdump can now be copied in multiple instances. Each instance will
show up a different interface and will have its own profile.
This will help users connecting to different hosts. Instead of changing
profiles, sshdump can be cloned, and each instance will be used for a
single host.

androiddump determines encap type by reading the data link type
value from pcap content generated by tcpdump running on the device.
The data link type is converted from an uint type to an int type
because int is what the pcap/wtap API expects. However the signed
to unsigned conversion is performed on an 8-bit data value rather
than the full 32-bit value making DLT values larger than 127 fail.
Fix the unsigned to signed conversion by determining DLT from the
full 32-bit "network" field from pcap global header instead of
the 8-bit data char array. While at it also take caore of device
