2015-11-04Don't include stuff from libwireshark.Guy Harris1-3/+0
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.)

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. svn path=/trunk/; revision=46748
