2018-11-09Dumpcap+Qt: Add support for `-a packets:NUM` and `-b packets:NUM`.Gerald Combs1-0/+10
Add the ability to rotate files after a specified number of packets (`-b packets:NUM`). Move some condition checks to capture_loop_write_packet_cb. Add `-a packets:NUM` in order to be consistent. It is functionally equivalent to the `-c` flag. Add a corresponding "packets" option to the Capture Interfaces dialog Output tab. Add initial tests for autostop and ringbuffer conditions.

2018-08-13Put the interface descrptions into the IDB when capturing to pcapng.Guy Harris1-110/+166
capture_opts_add_iface_opt(), when called in a program acting as a capture child, will fetch the description for the interface, and will also generate a "display name" for the interface. In the process, we clean up capture_opts_add_iface_opt() a bit, combining duplicate code. We rename console_display_name to just display_name, as it may also be used in the title bar of Wireshark when capturing.

2017-08-22Add hardware timestamping supportAhmad Fatoum1-17/+47
pcap provides a pcap_set_tstamp_type function, which can be used to request hardware timestamps from a supporting kernel. This patch adds support for aforementioned function as well as two new command line options to dumpcap, wireshark and tshark: --list-time-stamp-types List time stamp types supported for the interface --time-stamp-type <type> Change the interface's timestamp method Name choice mimics those used by tcpdump(1), which already supports this feature. However, unlike tcpdump, we provide both options unconditionally. If Wireshark was configured without pcap_set_tstamp_type being available, --list-time-stamp-types reports an empty list.

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.

2016-07-30extcap: Use stderr to print error messageRoland Knall1-0/+2
This patch reads out the stderr messages from an extcap utility and displays it to an user. It was tested on Qt but not on GTK, but should work their as well. On Mac OS/X and Windows the child_watch does not behave as it was intended. Therefore in extcap_cleanup, the callbacks are called manually, if and only if, they have not been called already. The reason why it displays two error messages is, that by the time the first one is being displayed, glib has not returned from the spawned process on Linux yet. So there is no way to add the stderr correctly, and putting a handler to stderr into interface_opts will lead to memory errors, cause then the code tries to access memory outside of its protection.

Have wsutil/file_util.h include them on UN*X, just as it includes io.h on Windows, so we can have a rule of "if you do file operations, include <wsutil/file_util.h> and use the routines in it". Remove includes of unistd.h, fcntl.h, and sys/stat.h that aren't necessary (whether because of the addition of them to wsutil/file_util.h or because they weren't needed in the first place).

Dumpcap captures packets, and supports the usual capture options, so it needs this, but it does *not* link with libwireshark (deliberately, so that the libwireshark code isn't linked into a program that might run with special privileges), so we must not depend on anything in libwireshark.

2015-11-04Don't include "file.h" if you don't need it.Guy Harris1-0/+2
It ends up dragging in libwireshark headers, which programs not linking with libwireshark shouldn't do. In particular, including <epan/address.h> causes some functions that refer to libwireshark functions to be defined if the compiler doesn't handle "static inline" the way GCC does, and you end up requiring libwireshark even though you shouldn't require it. Move plurality() to wsutil/str_util.h, so that non-libwireshark code can get it without include epan/packet.h. Fix includes as necessary.

2015-03-25Have a #define for whether the capture buffer size can be set.Guy Harris1-6/+6
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.

2014-08-21Extcap Capture InterfaceRoland Knall1-0/+36
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 Change-Id: I4f1239b2f1ebd8b2969f73af137915f5be1ce50f Signed-off-by: Mike Ryan <mikeryan+wireshark@lacklustre.net> Signed-off-by: Mike Kershaw <dragorn@kismetwireless.net> Signed-off-by: Roland Knall <rknall@gmail.com> Reviewed-on: https://code.wireshark.org/review/359 Petri-Dish: Michael Mann <mmann78@netscape.net> Tested-by: Petri Dish Buildbot <buildbot-no-reply@wireshark.org> Reviewed-by: Michael Mann <mmann78@netscape.net>
2014-07-22Get rid of NO_INTERFACES_FOUND - it's not an error.Guy Harris1-9/+3
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.)
