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.

Guy Harris cb16dff992 Get rid of more tvb_get_nstringz* calls.
Add an FT_STRINGZPAD type, for null-padded strings (typically
fixed-length fields, where the string can be up to the length of the
field, and is null-padded if it's shorter than that), and use it.  Use
IS_FT_STRING() in more cases, so that less code needs to know what types
are string types.

Add a tvb_get_stringzpad() routine, which gets null-padded strings.
Currently, it does the same thing that tvb_get_string_enc() does, but
that might change if we don't store string values as null-terminated
strings.

Hadriel Kaplan b63b503456 Fix Bug 9938 'tshark "-Y -2 -w" saves non-dependent frames'
When the '-Y' display filter option is given with a '-2', and a '-w' to write out
the packets, tshark grabs *all* dependent frames in the catprue file, even those
that weren't dependents of a matching packet. Note that this also uses the '-2'
two-pass option, since only two-pass mode writes out dependent frames to begin with.

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)

Hadriel Kaplan 041f844d72 Add command-line arg for input file format for tshark/wireshark
Now that we have the ability to choose input file format type
in the GUI, we might as well have it in the command-line too.
Plus it would help me in test-stuies if we had a commandline.
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?)

thing as the display filter (-Y) in that case except with more confusing
semantics.

This also lets us fix -c in the single-pass case to unconditionally count
packets. This isn't the old behaviour (which counted them only if they passed
the read filter) but is more consistent with two-pass mode where they are
counted even if they pass the display filter, since they are counted on the
first pass and the display filter is applied on the second pass.

Anyone who wants to use -c to limit packet count conditionally on them passing a
filter should use it in tandem with -2 and -R: the read filter is applied on the
first pass before the count.

Guy Harris 8c9edf1280 Have the seek-read routines take a Buffer rather than a guint8 pointer
as the "where to put the packet data" argument.

This lets more of the libwiretap code be common between the read and
seek-read code paths, and also allows for more flexibility in the "fill
in the data" path - we can expand the buffer as needed in both cases.

If we're not doing dissection (in 2-pass mode) then don't try to mark frames
as depended upon: in that case epan has not been initialized so we shouldn't
be looking in the edt (and anyway without dissection there won't be any
dependent frames).

(I'm not convinced there's any reason to run 2-pass mode without dissection,
however...)

Guy Harris 9ac21fd6cc AAAAAArgh. The capture_input_new_XXX routines are called from
capture_sync.c, not from capture.c, so they should be declared in
capture_sync.h, so callers that use the capture_sync.c stuff but not the
capture.c stuff - such as TShark - get the declarations and get their
implementations compared with the signatures that they should have.

Doing so points out that some of them in TShark *don't*, so fix that.

In Wireshark on Windows, create a console before doing so and destroy it
before exiting.  Don't do that in TShark or dumpcap, as those are
console-mode programs on Windows.

This should fix bug 8609 and still allow "wireshark -D" and "wireshark

It's a bit of a hack, but this entire area of 2-pass analysis etc. is a giant

Cast away some implicit 64-bit-to-32-bit conversion errors due to use of

Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
strtol() and strtoul().

Change some data types to avoid those implicit conversion warnings.

When assigning a constant to a float, make sure the constant isn't a
double, by appending "f" to the constant.

Constify a bunch of variables, parameters, and return values to
eliminate warnings due to strings being given const qualifiers.  Cast
away those warnings in some cases where an API we don't control forces
us to do so.

Enable a bunch of additional warnings by default.  Note why at least
some of the other warnings aren't enabled.

randpkt.c and text2pcap.c are used to build programs, so they don't need
to be in EXTRA_DIST.

If the user specifies --enable-warnings-as-errors, add -Werror *even if
the user specified --enable-extra-gcc-flags; assume they know what
they're doing and are willing to have the compile fail due to the extra
GCC warnings being treated as errors.

Anders Broman 28474fe8ef From Mike Garratt:
Friendly Names for interfaces on Windows

Notes on the changes the patch covers:
* if_info_t struct: addition of friendly_name
* Dumpcap Interface list format changes:
  + Win32: "dumpcap -D" shows friendly_name in place of descript if known
  + All: machine interface "dumpcap -D -Z none" includes friendly_name in the
list in addition to the existing parameters
* interface_options struct: addition of console_display_name
  + When an interface name is displayed in a console, it will typically be the
console_display_name (instead of name). 
  + console_display_name is used as the basis of the autogenerated temp
filenames
  + console_display_name is typically set to the friendly_name if known,
otherwise it is set to the interface name
* Enhancements to capture_opts_add_iface_opt() (the function which process -i
options).
  + Can now specify the interface using its name and friendly_name
  + Interface name matching is case insenstive
  + Name matching first attempts exact matching, then falls back to prefix
matching
    (e.g. dumpcap -i local)
  + Validates interface names, instead of blindly sending them off to
winpcap/libpcap
  + Interface specification by number is still supported.
* capture_opts_trim_iface() has been refactored:
  + Instead of repeating a decent chunk of the cost in
capture_opts_add_iface_opt(), it calls capture_opts_trim_iface() to specify the
interface.
* introduction of capture_win_ifnames.[ch] (windows only code)
  + Implements static function GetInterfaceFriendlyNameFromDeviceGuid() - a
windows version independant function to convert an interface guid into its
friendly name.  Uses published api functions on windows vista and higher, but
falls back to unpublished API functions on older windows releases.
  + void get_windows_interface_friendlyname(/* IN */ char
*interface_devicename, /* OUT */char **interface_friendlyname); - extracts the
GUID from the interface_devicename, then uses
GetInterfaceFriendlyNameFromDeviceGuid() to do the resolution
* Auto temp filename generation:
  + Now uses wireshark_pcapng_* or  wireshark_pcap_* depending on file format
  + Basis temp filename format on console_display_name
  + Win32: if console_display_name is a windows interface guid, extracts
numbers from GUID here (instead of in interface option processing) 

GUI CHANGES:
* Dialog that displays when you click the "Manage Interfaces" button (within
Capture Options dialog) has been renamed from "Add new interfaces" to
"Interface Management"
* ui/gtk/capture_dlg.c: new_interfaces_w variable renamed to
interface_management_w
* Win32: Local Interfaces tab on Interface Management dialog, shows includes
friendly name as far left column
* Interface Management dialog defaults to larger size on win32 - so it fits
without resizing local interfaces tab
* Interface Management dialog now saves preferences when you click the apply
button (local hidden interfaces was not persisting across restarts)
* Tweaks: "Interface Details" dialog (Interface list->Capture Interfaces ->
Details):
  + "Friendly Name" renamed to "NDIS Friendly Name"
  + Added "OS Friendly Name" to the top of the list
* Win32: The "Capture Interfaces" dialog now shows the friendly name instead of
device guid
* Welcome screen:
  + The height of the interface list scrollbox dynamically adjusts & updates to
the number visible interfaces.
    Up to 10 interfaces can be listed without a scroll bar, the minimum height
is for 2 interfaces. 
  + Win32: now shows just the Friendly Name if known - in place of
"Interfacename_Guid:(Description)"
