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.

Guy Harris 6db77b000f Allow wtap_read() and wtap_seek_read() to return records other than packets.
Add a "record type" field to "struct wtap_pkthdr"; currently, it can be
REC_TYPE_PACKET, for a record containing a packet, or
REC_TYPE_FILE_TYPE_SPECIFIC, for records containing file-type-specific
data.

Modify code that reads packets to be able to handle non-packet records,
even if that just means ignoring them.

Rename some routines to indicate that they handle more than just
packets.

We don't yet have any libwiretap code that supplies records other than
REC_TYPE_PACKET or that supporting writing records other than
REC_TYPE_PACKET, or any code to support plugins for handling
REC_TYPE_FILE_TYPE_SPECIFIC records; this is just the first step 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.

Start of refactoring Wiretap and breaking structures down into "generally useful fields for dissection" and "capture specific". Since this in intended as a "base" for Wiretap and Filetap, the "wft" prefix is used for "common" functionality.

The "architectural" changes can be found in cfile.h, wtap.h, wtap-int.h and (new file) wftap-int.h. Most of the other (painstaking) changes were really just the result of compiling those new architecture changes.

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.

Hadriel Kaplan c8a98f37ec Fix lua file testsuite not working and weak heuristic readers not being registered
The testsuite for Lua file reader/writer uses the acme_file.lua script to
generate a pcapng file from an Acme sipmsg.log file. It then compares the
tshark verbose output of this new pcapng file to a sip.pcapng file in
the test/captures directory that was previously made. Unfortunately, the
acme_file.lua script generates a timestamp based on local system timezone,
rather than UTC, so the testsuite fails if not run in the EST timezone where
the sip.pcapng file was originally made. This has now been fixed.

Also, trying to register new weak heuristic readers fails because the GArray
is terminated with a NULL-based row without Glib knowing about that. So this
commit changes it to let Glib handle the NULL-terminated row, so that appending
takes it into account automatically.

Michal Labedzki 579e7e19ce Wireshark: Add option to choose format type of capture file
The best heuristic can fail, so add possibility to manually choose
capture file format type, so not correctly recognize file format can be
loaded in Wireshark.

On the other side now it is possible to open capture file
as file format to be dissected.

Guy Harris 9a26416e3e Have macros to handle the range check and byte swapping.
Combine the check for whether the field is within the packet data and
the swapping of the field into macros that do both, and use them.

Guy Harris 63479adf63 Make some routines take a struct wtap_pkthdr * as an argument.
For some routines that take multiple arguments that come from a struct
wtap_pkthdr, pass a pointer to the struct wtap_pkthdr in question,
rather than the separate arguments.  Do this even if we're passing
expressions that were earlier assigned to the struct wtap_pkthdr fields
in question.  This simplifies the calling sequences and ensures that the
right values are picked up by the called routine; in at least one case
we were *not* passing the right values (the code to handle Simple Packet
Blocks in pcap-ng files).

Also, call the byte-swapping routines for pseudo-header fields only if
we need to do byte-swapping.

Guy Harris 90d7c5f59b Don't write out packets that have a "captured length" bigger than we're
willing to read or that's bigger than will fit in the file format;
instead, report an error.

For the "I can't write a packet of that type in that file type" error,
report the file type in question.

Evan Huus dae86605b6 Reject pcap files that claim on-the-wire packet sizes > 64MB. This fixes many
heuristic cases broken in r49999 when we permitted packets > 64KB, since that
relaxed so severely the definition of a valid packet header.

64MB is an arbitrary and perhaps suboptimal number, but it seems to do the right
thing in all the examples I have handy.

Michael Mann bf284da2ee TFShark (Terminal Fileshark) v.001. Bug 9607 (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9607)
This is a VERY PRELIMINARY version of tfshark.  It's an attempt to jumpstart FileShark and its architecture.  Right now it's mostly just a very stripped down version of tshark with all of the necessary build modifications (including now building filetap library since tfshark depends on it)

This code has helped me identify what I believe to be all of the necessary layers for a complete fileshark architecture.  And those layers will slowly be added in time (patches always welcome!).
