Guy Harris 9bf40d4a6e Do the right check for "no name resolution information to save".
The check that the pcapng code does is "do we have a non-null
addrinfo_lists_t * and, if so, does it have a non-null ipv4_addr_list or
ipv6_addr_list"?

The check that the file-save code was using was just "do we have a
non-null addrinfo_lists_t *", so sometimes it'd think we couldn't do a
"quick save" even though we had no name resolution information to write
out to the capture file.

Make a routine that does that check, and use it in *both* places.

Guy Harris 797d2f6a87 Move the frame_set stuff back into the capture_file structure.
libwireshark now expects an epan_t to be created with a pointer to a
"packet provider" structure; that structure is opaque within
libwireshark, and a pointer to it is passed to the callbacks that
provide interface names, interface, descriptions, user comments, and
packet time stamps, and that set user comments.  The code that calls
epan_new() is expected to provide those callbacks, and to define the
structure, which can be used by the providers.  If none of the callbacks
need that extra information, the "packet provider" structure can be
null.

Have a "file" packet provider for all the programs that provide packets
from a file.

Anthony Coddington f3181f706b ERF_TYPE_META write and comment support
Support per-packet comments in ERF_TYPE_META through a new Anchor ID
extension header with per-Host unique 48-bit Anchor ID which links an
ERF_TYPE_META record with a packet record. There may be more than one
Anchor ID associated with a packet, where they are grouped by Host ID
extension header in the extension header list. Like other ERF_TYPE_META
existing comments should not be overwritten and instead a new record
generated. See erf_write_anchor_meta_update_phdr() for detailed comments
on the extension header stack required.

As Wireshark only supports one comment currently, use the one one with
the latest metadata generation time (gen_time). Do this for capture
comment too.

Write various wtap metadata in periodic per-second ERF_TYPE_META records
if non-WTAP_ENCAP_ERF or we have an updated capture comment.
Refactor erf_dump to create fake ERF header first then follow common
pseudoheadr and payload write code rather than two separate code paths.
Support an ERF_HOST_ID environment variable to define Wireshark's Host
ID when writing. Defaults to 0 for now.

ERF dissector updates to support Anchor ID extension header with basic
frame linking.
Update ERF_TYPE_META naming and descriptions to official name
(Provenance)

Core changes:
Add has_comment_changed to wtap_pkthdr, TRUE when a packet
opt_comment has unsaved changes by the user.
Add needs_reload to wtap_dumper which forces a full reload of the file
on save, otherwise wireshark gets confused by additional packets being
written.

Daan De Meyer 07f576ffeb Add --no-duplicate-keys tshark option.
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).

testCaptureFileClose can also be invoked while reading an existing
capture file (the original comment only applied to GTK+, not Qt). When
the user quits Wireshark while reading an offline pcap, this could
result in a confusing "Unsaved packets" dialog. Fix this by checking the
actual capture session state.

After fixing this, the next issue is that cf_close trips on an assertion
("cf->state != FILE_READ_IN_PROGRESS"). To address this problem, do not
close the capture file immediately, but signal to the reader (cf_read)
that this should be done (similar to the quit logic in GTK+).

for an example of the problems caused by limiting the snapshot length to
256KB for D-Bus.

Have a snapshot length of 0 in a capture_file structure mean "there is
no snapshot length for the file"; we don't need the has_snap field in
that case, a value of 0 mean "no, we don't have a snapshot length".

In dumpcap, start out with a pipe buffer size of 2KB, and grow it as
necessary.  When checking for a too-big packet from a pipe, check
against the appropriate maximum - 128MB for DLT_DBUS, 256KB for
everything else.

Guy Harris 2a3f1a4f67 Eliminate some double-frees.
The cfile_ error-reporting routines free err_info; the caller doesn't
have to and, in fact, mustn't do so themselves.

While we're at it, make sure wtap_seek_read() always zeroes out *err and
nulls out *err_info, so the latter either points to a freshly-allocated
string or is null.

Guy Harris 64ec2b2e5e Take the error message generation out of the merge_files routines.
Have them just return the information needed for the caller to produce
an error message, and have the callers use the new cfile_ routines for
reporting errors.

This requires that the "write failure alert box" routine take the
*input* file name as an argument, so that, on a merge, if the problem is
that a record from a given input file can't be written out to the type
of output file we're generating, the input file name can be given, along
with the record number in that file.

cooking up a fake tap with a fake filter to do that).

Update MATE and TRANSUM to use it.

Jim Young 520a1b2066 Make the capture file's interface description filterable
This patch introduces the frame.interface_description field.

While testing this new functionality it became obvious that we have
a non-optimal interaction between the existing cfile.c's
cap_file_get_interface_name(), the recently added frame.interface_name
field and this new frame.interface_description field.

The string returned from cap_file_get_interface_name() may in fact
come from one of three different sources: the idb's interface name
(if it exists) or the idb's interface description (if that exists)
or a default text of "unknown".  The string ultimately becomes the
rame.interface_name whether or not the idb had an interface name
option to begin with.  This behavior does not allow one to test for
the simple presence of frame.interface_name.  The new peer function
cap_file_get_interface_description() added by this patch returns
NULL instead of "unknown" if the idb does not have an interface
description.  Should cap_file_get_interface_name() be similarly
modified to return NULL if the idb does not have an interface name?

	and fail if there is;

	"set" routines add an instance if there isn't one already
	and change the value of the existing instance if there is one;

	"set nth" routines fail;

	"get" routines return the value of the instance if there is one
	and fail if there isn't;

	"get nth" routines fail.

For "multiple instances allowed" options:

	"add" routines add an instance;

	"set" routines fail;

	"set nth" routines set the value of the nth instance if there is
	one and fail otherwise;

	"get" routines fail;

	"get nth" routines get the value if the nth instance if there is
	one and fail otherwise.

Rename "optionblock" to just "block"; it describes the contents of a
block, including both mandatory items and options.

Michael Mann 08d49ff2e0 Making wiretap option blocks more generic.
This was inspired by https://code.wireshark.org/review/9729/, but takes it in a different direction where all options are put into an array, regardless of whether they are "standard" or "custom".  It should be easier to add "custom" options in this design. Some, but not all blocks have been converted.
Descriptions of some of the block options have been moved from wtap.h to pcapng.h as it seems to be the one that implements the description of the blocks.

Also what could be added/refactored is registering block behavior.

Stig Bjørlykke 651d860d90 Don’t adjust time column widths in cf_open
The time column widths should not be adjusted in cf_open() because
we don’t have any packets yet and Qt resizeColumnToContents() will
not adjust any widths but emits a sectionResized() with invalid or
default values (new_width seems to always be 32).  This will in some
cases (when start capturing packets) give wrong width values which
is later stored in the recent file, and the time columns may end up
narrow the next time the recent file is read.

This fix is related to the column with issues previously compensated
for in PacketList::sectionResized() (g4980d505).

Stig Bjørlykke cc679ca5ce Qt: Add check for field extractors
The proto tree is needed in several cases when using Lua field extractors,
because they fetch values from the tree.  Without a valid field extractor
a Lua plugin may misbehave and display wrong column info.

This fixes column issues when:
- Calling resetColumns() in Qt.  This involves adding a display filter,
  change time display format, change name resolution and other changes
  in UI which requires column updates.
- Print summary lines.
- Export as CSV and PSML.

Peter Wu 5539dba1df Do not apply color rule filter every dissection
Introduce a frame_data flag "need_colorize" to indicate that coloring
rules need to be evaluated and set it for the GUI (not tshark). This
restores the original performance characteristics.

It additionally fixes a regression where the color filter name and
filter is not shown anymore in the tree (I guess it is related to the
edt->tree being NULL when re-selected, resulting in empty color_filter).

Remaining problems:

 - Display filter cannot contain frame.coloring_rule.* fields. Code is
   present to enable this, but then a method is needed to avoid an
   expensive second calculation (which is why it is disabled).
 - The columns are still not updated after coloring rule change.
 - The two frame.coloring_rule fields in the tree are not updated when
   the coloring rule is changed (e.g. Ctrl-1).

The last two issues were supposed to be fixed by the previous patch, but
there is probably some missing code... Tested with GTK and Qt.

Guy Harris 1871fb2b0d Keep a captured-packet count in a capture_session and use that.
Have the count in a cfile_t structure always reflect the actual number
of packets that have been read from the file, rather than, when doing a
non-update-list-of-packets-in-real-time capture, falsely increasing the
count in the cfile_t to reflect the number of packets captured but not
yet read.

Have the status bar base its captured-packet count on the count in the
capture_session structure, and base the "sorry, no packets were
captured" message on the count in the capture_session structure, as
we're no longer using the count in the cfile_t structure to count
anything in the process of a non-update-list-of-packets-in-real-time
capture.

That way, we preserve the invariant that the "frames" member of a
cfile_t will be non-null if the "count" member is non-zero, fixing bug
6217.

It also means we can get rid of cf_set_packet_count(), as we only set
the count in the capture-file-reading code.

Guy Harris 318cf8a678 Add support for dissecting non-packet records.
Add a dissector table indexed by the file type, and, for the
file-type-specific records, have the frame dissector skip the usual
pseudo-header processing, as the pseudo-header has a file-type-specific
record subtype in it, and call the dissector for that file type's
records.

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.

Guy Harris a344c9736e Revert "Allow wtap_read() and wtap_seek_read() to return non-packet records."
This reverts commit c0c480d08c.

A better way to do this is to have the record type be part of struct wtap_pkthdr; that keeps the metadata for the record together and requires fewer API changes.  That is in-progress.

Guy Harris c0c480d08c Allow wtap_read() and wtap_seek_read() to return non-packet records.
This is the first step towards implementing the mechanisms requestd in
bug 8590; currently, we don't return any records other than packet
records from libwiretap, and just ignore non-packet records in the rest
of Wireshark, but this at least gets the ball rolling.

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.

Michael Mann 1abeb277f5 Refactor Wiretap
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.

Peter Wu dfb92dfd67 Fix crash when switching profiles
rescan_packets() starts a new dissection session by free'ing the
previous state and creating a new one. A reference to the old session
was not updated though.

This is the only place where epan is overwritten. After init, col_init
will at some point initialize cf->cinfo.epan with a cf->epan.

Gerald Combs a5cb72fe9e Add a Qt I/O Graph dialog.
For each graph you can set:
- Its visibility
- A name
- A display filter
- Color, from a fixed list
- Plot style: Line, Impulse, Bar, Stacked Bar, Dot, Square, Diamond
- Basic Y Axes (packets/s, bytes/s, bits/s)
- Computed Y Axes (SUM, MIN, AVG, MAX)
- Smoothing

You can pan and zoom using the mouse and keyboard. Clicking on a graph
selects the last packet for that interval. If all graphs have the same Y
axis a single label is shown, otherwise a legend is shown.

The time scale (X axis) can be toggled between relative seconds and the
time of day.

Graphs can be saved as PDF, PNG, BMP, and JPEG. Settings are "sticky"
via the io_graphs UAT.

To do:
- Minimize graph drawing delays.
- Figure out why smoothing differs from GTK+
- Everything else at the top of io_graph_dialog.cpp
- Fix empty resets.

A fair amount of code was copied from TCPStreamDialog. We might want to
subclass QCustomPlot and place the shared code there.

Move common syntax checking to SyntaxLineEdit.

Move some common code from ui/gtk/io_stat.c to ui/io_graph_item.[ch] and
use it in both GTK+ and Qt.

Make the io_graph_item_t array allocation in io_stat.c static. The
behavior should be identical and this gives us additional compile-time
checks.

Hadriel Kaplan ca9c160933 Fix bug9931 'Encapsulated ethernet packets sometimes show invalid FCS'
This fixes part-1 of bug9931: the uninitialized use of a wtap_pkthdr
struct. The second part of the bug deals with dissectors calling
the Ethernet dissector for ecnapsulated Ethernet packets but using
the wrong dissector handle to do so. That's unrelated to the issue this
commit addresses, so I'm splitting them up.

Hadriel Kaplan d1873dbcc8 Fix Bug 9903: 'Clicking reload-file ignores selected file format reader'
There's a relatively new feature in 1.11.3 to select a specific file format
reader, instead of relying on magics or heuristics. If you select a file
reader and open a file, open it, and then click the reload-file button or go
to View->Reload or press the ctrl-R keymap, the file is reloaded but using the
magic/heuristics again instead of the file format reader you previously chose.
Likewise, the Lua relaod() function has the same issue (which is how I found
this problem).

I have tested this change by hand, using a Lua script, but I didn't add it
to the testsuite because I need another change for my test script to work
correctly. (an enhancement rather than a bug fix, which I'll submit separately)
