2016-01-07Move more capture device handling to the caputils library.Guy Harris1-15/+10
Move the code to open capture devices and get properties of capture devices there, joining the code to get a list of capture devices. This lets us do a better job of handling pcap_create() in WinPcap, including handling both WinPcap with pcap_create() and WinPcap without pcap_create() at run time, just in case somebody tries using WinPcap 3.x with a Wireshark built with WinPcap 4.x. It also could make it easier to use libpcap/WinPcap directly in Wireshark and TShark, if we have versions of libpcap/WinPcap that run small helper utilities to do privileged functions, allowing programs using them never to need elevated privileges themselves. That might make it easier to fix some issues with running TShark when not saving to a file (we could avoid the file entirely) and with delays when stopping a capture in Wireshark (Wireshark could stop writing to the file as soon as you click the stop button, rather than letting dumpcap do so when the signal gets to it). It might also make it easier to handle future versions of libpcap/WinPcap that support using pcap_create()/pcap_activate() for remote captures, and other future extensions to libpcap/WinPcap. Rename some XXX_linktype routines to XXX_datalink to indicate that they work with DLT_ values rather than LINKTYPE_ values; future versions of libpcap might use LINKTYPE_ values in newer APIs. Check for pcap_create() on all platforms in CMake.

2015-03-25Have a #define for whether the capture buffer size can be set.Guy Harris1-1/+12
It can be set if either 1) this is Windows (where we're assumed to be using WinPcap, which includes calls to set the buffer size) or 2) we have pcap_create() (in which case we also have pcap_set_buffer_size(), at least in a normal libpcap release). Use that rather than testing "defined(_WIN32) || defined(HAVE_PCAP_CREATE)"; that makes it a bit more obvious what's being tested.

2015-01-04No *pcap should have pcap_open() without the other remote extensions.Guy Harris1-3/+1
WinPcap 3.0 introduced pcap_open(); it also introduced pcap_findalldevs_ex() and pcap_createsrcstr(). If you're going to put pcap_open() in libpcap, there's not much point to doing so but not also putting pcap_findalldevs_ex() and pcap_createsrcstr() there. (And, in the future, there'll be support for remote capturing with pcap_create() and pcap_activate(), with no need for pcap_createsrcstr(), and a replacement for pcap_findalldevs() and pcap_findalldevs_ex(), which we'll also check for.) So there's no need to check for pcap_findalldevs_ex() or pcap_createsrcstr().

2014-09-28Add support for getting nanosecond time stamp resolution when capturing.Guy Harris1-0/+1
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.
