2017-06-05Allow bigger snapshot lengths for D-Bus captures.Guy Harris1-8/+8
Use WTAP_MAX_PACKET_SIZE_STANDARD, set to 256KB, for everything except for D-Bus captures. Use WTAP_MAX_PACKET_SIZE_DBUS, set to 128MB, for them, because that's the largest possible D-Bus message size. See https://bugs.freedesktop.org/show_bug.cgi?id=100220 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.

pcap_create()/pcap_activate(). Just let libpcap pick the snapshot length; that way, for link-layer types that need a really large snapshot length, such as D-Bus (which requires 128MB for the largest messages), it can pick that, but can otherwise pick something that doesn't require as much memory, e.g. 256KB. For pcap_open_live() and pcap_open(), which don't have a way of saying "give me what's appropriate", pick 256KB.

2017-05-11Force HAVE_REMOTE to be defined when including pcap.h with remote support.Guy Harris3-0/+36
WinPcap made the mistake of having stuff in its public header fines depend on a configuration #define, HAVE_REMOTE; this means that we need to forcibly define it when building with remote capture support. The tip of the libpcap master branch does not have that botch; hopefully future versions of libpcap-for-Windows will be based on that libpcap and thus lack that botch as well. Defining HAVE_REMOTE in config.h is not the right fix, as it makes it look like a *Wireshark* configuration option that code in Wireshark should test, rather than a *WinPcap* configuration option that the pcap.h that ships with the WinPcap SDK should have been changed, as part of the build process, to correctly define or not, so that users of WinPcap don't have to define it themselves.

Return an error string if that happens. If it doesn't fail, it will return a value >= 1; it will never return 0, so don't check for that. Change-Id: I6d7ee2683c1ceae73e9d9d61c0a6e6d30b2c4400 Reviewed-on: https://code.wireshark.org/review/13100 Reviewed-by: Guy Harris <guy@alum.mit.edu>

2016-01-07Move more capture device handling to the caputils library.Guy Harris5-23/+834
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.

2016-01-06Remove unnecessary #ifdef and includes.Guy Harris1-7/+0
We don't check HAVE_LIBPCAP elsewhere, and we do use GLib functions, but don't use the GLib dynamic-loading APIs ourselves, and don't appear to use anything from libpcap or libwiretap, so include only <glib.h> and include it unconditionally.
