Guy Harris dbdcae80ba Rename WTAP_ERR_UNSUPPORTED_ENCAP to WTAP_ERR_UNWRITABLE_ENCAP.
That makes it clearer what the problem is, and that it should only be
returned by the dump code path, not by the read code path.

Use the "MCS index used" extended flag bit to indicate whether the "data
rate or MCS index" field is a data rate or MCS index.

Display the MCS index value if it's present.

(More to come - MCS indices, plus other information, should be used to

Guy Harris a566f617d8 No need for WTAP_ERR_CANT_READ.
Unlike the standard I/O routines, the code we introduced that supports
fast random seeking on gzipped files will always supply some specific
error code for read errors, so we don't need WTAP_ERR_CANT_READ.

Add WTAP_ERR_CANT_WRITE for writing, as we're still using the standard
I/O routines for that.  Set errno to WTAP_ERR_CANT_WRITE before calling
fwrite() in wtap_dump_file_write(), so that it's used if fwrite() fails
without setting errno.

Otherwise, if you link with both libwiretap and libfiletap, it's
anybody's guess which one you get.  That means you're wasting memory
with two copies of its routines if they're identical, and means
surprising behavior if they're not (which showed up when I was debugging
a double-free crash - fixing libwiretap's buffer_free() didn't fix the
problem, because Wireshark happened to be calling libfiletap' unfixed
buffer_free()).

There's nothing *tap-specific about Buffers, anyway, so it really

Guy Harris 6dffc3b7e3 Distinguish between "events" and "reports".
Have two different classes of file-type-specific records - "events" and
"reports".  An "event" indicates something that happened in the capture
process, such as a status transition on the network; a "report" just
gives information not corresponding to something happening in the
capture process, such as capture statistics.

Note that both of those should be dissected and displayed like packets,
and leave open the possibility of file-type-specific records whose
contents should be processed and saved but not displayed in the packet
list.

Shorten "file_type_specific" to "ft_specific".

Guy Harris 1b6cc6320e Add support for plugins to handle pcap-ng block types.
We rename "file format" plugins to "libwiretap" plugins, as they can
register as read handlers for a new file type, read/write handlers for a
pcap-ng block type (or both).

To register as a pcap-ng block type handler, in the
register_wtap_module() routine of your plugin, call
register_pcapng_block_type_handler() with the pcap-ng block type and
pointers to your routines to read and write those blocks.  Those
routines should read and write REC_TYPE_FILE_TYPE_SPECIFIC records, with
the block type in the pseudo-header for the record in the struct
wtap_pkthdr structure, with time stamps stored in that structure, and
with a blob of data for the rest of the record.

This is for bug 8590.

Peter Wu 3aee917058 wiretap: remove unused code, drop number_of_interfaces
While investigating an ASAN issue (fixed in
commit dcdd076ab0), I got greatly confused
by three different types having the same "interface_data" field name:

 * pcapng_t *pn stores an array of interface_data_t objects.
 * wtap *wth stores an array of wtapng_if_descr_t objects.
 * pcapng_dump_t should store an array of interface_data_t objects.

pcapng_dump_t and friends are unused since
commit c7f1a431d2, so drop it.

To fix the confusion, rename the interface_data_t type to
interface_info_t type and use the local variable "iface_info"
everywhere. Rename interface_data of pcapng_t to "interfaces" and
add a comment what this exactly means (interfaces listed in the capture
file).

Drop the number_of_interfaces field for interfaces as the array
length is already available from GArray. Now interface_data is always
initialized for wth (which also gets copied to idb).

s/int/guint/g and replace cast at some places.

There are no regressions for the in-tree test suite.

Christopher Kilgour 7b13a3b0f6 Allow pcapng interface options to be available to dissectors.
Interface options[1], and more generally pcapng options[2], are useful
information that can provide improved dissector output.

Prior to this change, only certain pcapng interface options were interpreted
and made available to dissectors, e.g. the interface name or description.
This change augments the situation by providing epan_get_interface_option( ),
which returns an array of byte arrays if the option code exists
(otherwise NULL).  Each element of the array is a byte buffer containing
the raw data of the option.  An array-of-buffers is used because pcapng
allows for multiple instances of the same option to be present in the file.
All interface options found in a pcapng file are thus made available to the
dissector.

The implementation also provides infrastructure to collect options from
other pcapng blocks such as the section header.  Currently these options
are discarded, but could be retained in the future to support more features.

So I've added a '-X read_format:Foo' for this.  Using just
'-X read_format:', or with a bad name, will make it print out
the full list (in tshark); just like the '-F' does for output
file formats.

Note: I am *not* putting in code for Win32 GUI,
because I can't compile that and I wouldn't have even
done the GTK one if I could compile Qt originally. (I don't think we need
to add any more features to GTK or Win32, just Qt from now on,
right?)

error messages for certain error codes.  (We should perhaps check for
even more error codes in those cases.)

Guy Harris 633de5c7d1 Add a routine that, given a set of packet encapsulation types, returns
the per-file encapsulation type needed to write out a set of packets
with all those encapsulation types.  If there's only one such
encapsulation type, that's the type, otherwise WTAP_ENCAP_PER_PACKET is
needed.  Use that in wtap_dump_can_write_encaps().

Also use it in cf_save_packets() and cf_export_specified_packets(), so
that we can write out files with WTAP_ENCAP_PER_PACKET as the file
encapsulation type and only one actual per-packet encapsulation type in
some cases where that failed before.  This fixes the case that showed up
in bug 7505, although there are other cases where we *could* write out a
capture in a given file format but won't be able to do so; fixing those
will take more work.

Guy Harris c63aa61658 Have wtap_get_savable_file_types() take an array of encapsulations and
only return file types that could handle a single file with all those
encapsulations - this means that

	1) if there's more then one encapsulation, the file format has
to handle per-packet encapsulation;

	2) just because a file format handles per-packet encapsulation,
that doesn't mean that it can handle the *particular* encapsulations
being handed to it.

This fixes some cases where we were claiming that a file could be saved
in a format that doesn't actually support it (e.g., ISDN files being
reported as savable in pcap-NG format - there's no LINKTYPE_ value for
ISDN including B and D channels).

Guy Harris e51c05a836 TShark doesn't need wtap_fdreopen(), as it doesn't do saves and thus
doesn't do safe saves, so wtap_fdreopen() always needs to reopen the
random file descriptor.

At the point where a safe save is done, the sequential read is done, so
the sequential stream is closed; there's no need to reopen it.

(The former fourth argument to wtap_fdreopen() wasn't an indication of
whether the file was compressed, it was an indicationof whether the
random stream should be reopened.)

Guy Harris 129c881fcf Sigh. There appears to be no way to get Windows to allow us to rename a
file that we ourselves have open.  In the "safe save" code path for
capture files, on Windows temporarily close the file descriptors for the
currently-open capture before doing the rename and then, if the rename
failed, reopen them, leaving the rest of the wtap and capture_file
structures intact.

Rename filed_open() to file_fdopen(), to make its name match what it
does a bit better (it's an fdopen()-style routine, i.e. do the
equivalent of an open with an already-open file descriptor rather than a
pathname, in the file_wrappers.c set of routines).

Remove the file_ routines from the .def file for Wiretap - they should
only be called by code inside Wiretap.

Closing a descriptor open for input has no reason to fail (closing a
descriptor open for *writing* could fail if the file is on a server and
dirty pages are pushed asynchronously to the server and synchronously on
a close), so just have file_close() return void.

Guy Harris cf6d9841e3 Keep track, in Wiretap, of whether the file is compressed, and provide
an API to fetch that.

When doing "Save" on a compressed file, write it out compressed.

In the Statistics -> Summary dialog and in capinfos, report whether the
file is gzip-compressed.

Guy Harris e6a57c8e93 In Windows, in the Save As and Export Selected Packets dialog, append
the default extension for the file type iff

	the file type we're using has a list of extensions;

	the file has no extension or it has one but it's not one of the
	ones in the list.

*Don't* expect a file extension to be at most 5 characters plus the dot
- the extension for pcap-ng, our default capture file type, is "pcapng",
and that's 6 characters!

Guy Harris 0275247b97 Use WTAP_ENCAP_IEEE_802_11_xxx for all the "802.11 plus radio header"
encapsulations.

For pre-V9 AiroPeek captures, leave the radio information in the packet
data, just as we do with the Prism, AVS, radiotap, and NetMon headers. 
Add a dissector for it.

Anders Broman 102991bf0f Handle wtap_dump_fdopen() as wtap_dump_open() eg call
wtap_dump_fdopen_ng() and add a dummy IDB to be able to write pcapng files.
Solves https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=6969
mergecap: Can't open or create <FILENAME>: Internal error.

We might want to add a SHB comment from mergecap giving the merged filenames or something like that, Merging of pcapng files
is a different issue, idealy we should probably start using several SHB:s in that case.

Martin Mathieson 45252c84e3 Patch for https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5048
From Tom Cook and Tom Alexander.

1. A VWR encapsulation that reads VeriWave capture files (*.vwr)
generated from
WaveTest test hardware
2. Dissectors that display the VeriWave tap headers (both 802.11 and
Ethernet)
3. A dissector for the WaveAgent protocol.  The WaveAgent dissector is
heuristic and parses the WaveAgent packet (a UDP payload).

The WaveAgent dissector has been Fuzz tested.

The VWR ENCAP and dissectors have been used extensively by VeriWave
customers in a special version of WireSark compiled by VeriWave.

Alexis La Goutte 6aedbbaf35 From Colus Tang via https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7134
Unable to display the correct IEEE802.11 MCS data rates due to header definition

The problem is due to the ieee_802_11_phdr.data_rate is defined as guint8,
since this variable is counting number of 0.5Mbps units, any datarates which is
higher than 255Mbps would get wrapped up.  In the above example, only the lower
8bit value will be put into the ieee_802_11_phdr which is 0x04 and result in
the incorrect 2Mbps display.

There are 802.11n WLAN product is capable to transmit @450Mbps, we should fix
this data_rate from guint8 to guint16.

Guy Harris 154c0f37dd Indicate where BACnet MS/TP is specified.
Add a new WTAP_ENCAP_BACNET_MS_TP_WITH_PHDR encapsulation type, for use
by the EyeSDN file reader; unlike the pcap-encapsulated MS/TP, it
includes a direction indicator.  Don't treat WTAP_ENCAP_BACNET_MS_TP as
if it has a direction indicator, as it doesn't; instead, do that for
WTAP_ENCAP_BACNET_MS_TP_WITH_PHDR.

Add some missing entries to encap_table_base for WTAP_ENCAP_ values that
didn't get entries added.
