Guy Harris 78492d9dd2 Cope with newer Xcode not having the 10.6 SDK.
The latest Xcode, as of today, has only 10.9 and 10.10 SDKs, which means
that, if we build Wireshark and request a deployment minimum release of
10.6, we'll be building against an SDK in which libpcap has routines
that aren't available in 10.6 and that doesn't use weak linking for
them, so the resulting binary won't actually work on 10.6.

Use the run-time loader to find those routines (currently, only
pcap_set_tstamp_precision()) and call them only if we find them.

On other UN*Xes, we still assume that we'll be running only on the
release against which we were built and newer releases.

Guy Harris 96835181e4 Pass the global capture options to open_capture_device().
If we support setting the time stamp precision, we need it to determine
whether we're writing a pcap-ng file so we know whether to request
nanosecond precision or not.

Guy Harris 392c41ce30 Add support for getting nanosecond time stamp resolution when capturing.
If we have pcap_set_tstamp_precision(), use it to request nanosecond
time stamp resolution *if* we're writing a pcap-ng file; any code that
reads those files and can't handle nanosecond time stamp resolution is
broken and needs to be fixed.

If we're writing a pcap file, don't ask for nanosecond resolution time
stamps, as that requires a different magic number for pcap files, and
not all code that reads pcap files can handle that.  (Unlike pcap-ng,
where the ability to have non-microsecond time stamp resolution was
present from Day One, it's a relatively recent addition to pcap.)  We
could add a command-line option/GUI option for that, like the option
recent versions of tcpdump have, if it matters.

Roland Knall bed29af46d Extcap Capture Interface
Extcap is a plugin interface, which allows for the usage
 of external capture interfaces via pipes using a predefined
 configuration language which results in a graphical gui.

 This implementation seeks for a generic implementation,
 which results in a seamless integration with the current
 system, and does add all external interfaces as simple
 interfaces.

 Windows Note: Due to limitations with GTK and Windows,
 a gspawn-winXX-helper.exe, respective gspawn-winXX-helper-console.exe
 is needed, which is part of any GTK windows installation.

 The default installation directory from the build is an extcap
 subdirectory underneath the run directory. The folder used by
 extcap may be viewed in the folders tab of the about dialog.

 The default installation directory for extcap plugins with
 a pre-build or installer version of wireshark is the extcap
 subdirectory underneath the main wireshark directory.

 For more information see:

  http://youtu.be/Nn84T506SwU
  bug #9009

 Also take a look in doc/extcap_example.py for a Python-example
 and in extcap.pod for the arguments grammer.

 Todo:
   - Integrate with Qt - currently no GUI is generated, but
     the interfaces are still usable

Guy Harris f6ce0cdacd Get rid of NO_INTERFACES_FOUND - it's not an error.
It just means "pcap didn't give me any interfaces, and didn't report an
error".  Hopefully, in the future, there will be pcap APIs that
distinguish between the (admittedly unlikely, these days) case of "there
really *are* no interfaces on which *anybody* can capture" and "you
don't have sufficient permission to capture", and we can report the
latter as an error.  (Given that pcap supports more than just "regular
interfaces", though, there are cases where you don't have permission to
capture on those but you have permission to capture raw USB traffic, for
example, so perhaps what's really needed is per-interface indications of
permissions.)

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)"

Guy Harris 3864d5d19d Add an additional DONT_HAVE_PCAP return value from get_interface_list()
and capture_interface_list().  Return it if, on Windows, we ask for the
interface list but don't have WinPcap installed.  Handle it like
CANT_GET_INTERFACE_LIST.

Guy Harris 21f5ea24e4 Just hard-code the error for "can't load WinPcap"; the one that
cant_load_winpcap_err() has some redundant gunk in it.

svn path=/trunk/; revision=40333
2011-12-29 22:06:22 +00:00
Guy Harris 71c7f43d37 On Windows, if we can't open a capture device, check whether WinPcap is
loaded and, if not, report that as the problem, rather than suggesting
that you didn't specify the proper interface.

Guy Harris d892f00916 Show a "Capturing on ..." message similar to TShark.
svn path=/trunk/; revision=39989
2011-11-22 19:07:49 +00:00
Guy Harris 939feef06f If we're not running as a child process, report the interfaces on which
we're capturing.  (We do not require a -i flag; the message could be
useful if you don't specify the interface, as it lets you know which
interface was chosen, which might not be the interface you'd think it
would be.  Yes, that's arguably a libpcap bug, which I plan to look at;
it should probably try to figure out which interfaces are "active" if
possible, and prefer those.)

Use cmdarg_err() for invalid capture filters and other capture errors.
