2014-05-28netsniff-ng: Add netlink dissectorTobias Klauser1-0/+2
Add an initial implementation of a dissector to work on netlink messages as received from an nlmon device. Use can use it as follows to monitor netlink traffic to/from the kernel: modprobe nlmon ip link add type nlmon ip link set nlmon0 up netsniff-ng -i nlmon0 ip link set nlmon 0 down ip link del dev nlmon0 rmmod nlmon Fixes: #89 Suggested-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-08-09dev: Integrate `promisc' module into `dev' moduleTobias Klauser1-1/+0
Since entering/leaving promiscuous mode also is a device specific function and all users of the `promisc' module also use `dev', integrate it there. Also rename the functions to have a `device_' prefix like the other functions in the module. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-07-30build: reduce Extra contents to bare minimumDaniel Borkmann1-0/+6
Improve the build system, so that configuration files are installed per tool basis. Also, introduce post_install targets, so that config files can be altered in some way, e.g. done by trafgen. Moreover, move custom targets from Extra to tool-specific Makefiles. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-12bpf_comp: pass NEED_TCPDUMP_LIKE_FILTER through gccDaniel Borkmann1-1/+1
We have to pass NEED_TCPDUMP_LIKE_FILTER define through gcc as it otherwise is not possible to let the pcap compiler invoke through netsniff-ng, but not through astraceroute. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-11dissector: rename __WITH_PROTOS into HAVE_DISSECTOR_PROTOSDaniel Borkmann1-1/+1
To be more consistent with config.h, rename __WITH_PROTOS into HAVE_DISSECTOR_PROTOS. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-11build: refactor tool specific flags into <tool>/MakefileDaniel Borkmann1-0/+4
To get the normal Makefile a bit cleaner, push the tool specific build options into <tool>/Makefile. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-11configure, netsniff-ng: if no libgeopip, do not link against libzDaniel Borkmann1-5/+5
In netsniff-ng, we only use libz in combination with libgeoip, so if we lack either one of them, do not link against the other either. This would be a waste otherwise. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-11configure, netsniff-ng: make netsniff-ng's geoip dependency optionalDaniel Borkmann1-3/+7
Geoip dependency should not be mandatory as it's not a core part of netsniff-ng. This also facilitates compilation on platforms where geoip is not available. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-09configure: fix multiple issues in build configurationDaniel Borkmann1-1/+3
This patch is a bundle of multiple fixes. 1) Fix compilation of astraceroute when HAVE_LIBPCAP=1: astraceroute doesn't need libpcap, so add an additional guard/define to bpf.h and bpf_comp.c and netsniff-ng.c. Also since we generate a config.h file, we do not need to have this additional compile flag anymore. 2) Fix tstamping.{h,c} to use the configure script instead of the Makefile. For doing this, also fix the object inclusion in netsniff-ng/Makefile. Last but not least, rename __WITH_... into HAVE_... as this is more clean. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-08configure: netsniff-ng: libpcap is not a hard dependencyDaniel Borkmann1-2/+8
netsniff-ng uses libpcap only for high-level filter compiling. Thus, let netsniff-ng not "hard-depend" on libpcap, but rather disable filter compiling in case the user does not want to install libpcap. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04xutils: eliminate xutils, move rest to epoll2Daniel Borkmann1-1/+0
Finally eliminate xutils.{c,h} and move the rest to epoll2. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>

2013-06-04proc: move out process specific management functionsDaniel Borkmann1-0/+1

2013-06-04privs: move drop_privileges out of xutilsDaniel Borkmann1-0/+1

2013-06-04xutils: move device management functions out of xutilsDaniel Borkmann1-0/+1

2013-06-04xutils: break out promisc mode functionsDaniel Borkmann1-0/+1
Put them separately for the sake of maintanence. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04xio: rename xio to ioops and reduce its includesDaniel Borkmann1-1/+1

2013-06-04xutils: break out string handling and lockingDaniel Borkmann1-0/+1

2013-05-31ring: move duplicate/generic code parts from rx/tx into ring.cDaniel Borkmann1-0/+1
We do not want to maintain duplicate code, so move this into a separate file and name those *_generic() helpers. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-13ring: break out timestamping since not directly relatedDaniel Borkmann1-0/+1
Break out the timestamping part of the ring.h file, since it's not directly related to the {t,r}x_ring. Also inlining doesn't make sense here. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>

2013-03-15all: import netsniff-ng 0.5.8-rc0 sourceDaniel Borkmann2-0/+54
We decided to get rid of the old Git history and start a new one for several reasons: *) Allow / enforce only high-quality commits (which was not the case for many commits in the history), have a policy that is more close to the one from the Linux kernel. With high quality commits, we mean code that is logically split into commits and commit messages that are signed-off and have a proper subject and message body. We do not allow automatic Github merges anymore, since they are total bullshit. However, we will either cherry-pick your patches or pull them manually. *) The old archive was about ~27MB for no particular good reason. This basically derived from the bad decision that also some PDF files where stored there. From this moment onwards, no binary objects are allowed to be stored in this repository anymore. The old archive is not wiped away from the Internet. You will still be able to find it, e.g. on git.cryptoism.org etc. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
