Jakub Zawadzki 5d52e16734 Add helper function to epan_session which can be used to get absolute timestamp of given frame.
Remove ->prev_cap, for testing purpose also replace ->prev_dis with number of previously displayed frame number.

This patch reduce size of frame_data by 8B (amd64)
This is what (I think) was suggested by Guy in comment 13 (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5821#c13)

Luis Ontanon 0bdc0efc46 get main_window_update out of the way... pass an update_cb to the capture_sync stuff
... as per the XXX comment removed from tshark.c this was a mess to keep the linker
happy... I couldn't!

I did this without even understanding whether calling main_window_update was realy
necessary in most cases. I guess nothing or more specific update cbs would be best.

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.

Chris Maynard fd1746412b Allow tshark to read a pcap file and either save it as a new pcap file or for packets to be read from the original pcap file, possibly filtered, then sent to stdout and piped to either tshark or wireshark, which can then read those filtered packets from stdin. Patch submitted by me in bug 2868, although it doesn't actually fix that bug.

Jeff Morriss 7dddfb1784 Fix https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=8714 :
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.

Guy Harris 39779a7bee Send the output of the -D and -L options to the standard output rather
than the standard error.

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
-L" to work when the standard output isn't redirected.

Add a 2-pass display-filter flag to tshark so that reassembly and other forward-
looking dissections can be used with filters.

It's a bit of a hack, but this entire area of 2-pass analysis etc. is a giant
pile of hacks to begin with and needs cleaning up. For now just having this
feature is a big enough win.

https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7530

The frame_data_cleanup function was ambiguous; it was being used for two
different purposes, and did neither of them quite properly. Split it instead
into frame_data_reset and frame_data_destroy, and call the correct one depending
on why we were originally calling frame_data_cleanup.

Guy Harris 8ed7a73e22 Fix a bunch of warnings.
Cast away some implicit 64-bit-to-32-bit conversion errors due to use of
sizeof.

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)"

Chris Maynard 573dd5b3dc 1) Allow for the possibility for both packet summary and packet details to be
printed when either -T is not specified or "-T text" or "-T ps" is selected.

2) Allow for packet hex/ascii to be printed without necessarily requiring that
either packet summary or packet details also be printed.  This just means that
if you want packet summary information, use "-Px" instead of just "-x".

3) Fix bug with order of evaluation of -V and "-T psml".

4) If a packet separator is specified, always use it regardless of the -PVx
options chosen.

5) Don't print 2 lines of separation between packets when only printing
hex/ascii.  Print 1 line of separation as in all other cases.

Fixes https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7782 plus other misc. enhancements.
