2013-06-04xutils: move device management functions out of xutilsDaniel Borkmann1-0/+1
Move those functions out so that they can be more easily maintained in its separate file. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-31ring: netsniff-ng: migrate capture only to TPACKET_V3Daniel Borkmann1-0/+7
Lets migrate capturing to TPACKET_V3, since it will bring a better performance due to fewer page cache misses caused by a higher density of packets, since now they are contigous placed in the ring buffer. It is said that TPACKET_V3 brings the following benefits: *) ~15 - 20% reduction in CPU-usage *) ~20% increase in packet capture rate *) ~2x increase in packet density *) Port aggregation analysis *) Non static frame size to capture entire packet payload Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-31ring: setup frame structure for v2/v3 in a generic wayDaniel Borkmann1-1/+1
Prepare TPACKET_V3 for allowing to transparently setting up the frame structure such that we do not need to change much in the netsniff-ng/trafgen code. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-31ring: move duplicate/generic code parts from rx/tx into ring.cDaniel Borkmann1-0/+4
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>
2013-05-31ring: fix wrong error message text in __get_sockopt_tpacketDaniel Borkmann1-1/+1
Arg, this was a leftover when copying the other function. So fix it! Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-31ring: implement setup of tpacket v3 ringDaniel Borkmann1-0/+18
Implement ring setup routines and structures for TPACKET_V3. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-30ring: prepare setup_rx_ring_layout for support in v2/v3Daniel Borkmann1-0/+7
Prepare setup_rx_ring_layout for both, v2 and v3. Also do some checks during compile time if offsets stay the same as we operate on different union mappings. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-30ring: add necessary structures and helper functions for v3Daniel Borkmann1-1/+10
Prepare and add some structures an helper functions for TPACKET_V3. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-30ring: move poll related fallback define to built_in.hDaniel Borkmann1-10/+0
It rather belongs to built_in.h, and not here. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-30ring: minor: remove define since only used onceDaniel Borkmann1-3/+1
We only use it once and nowhere else, so just replace the correct value right away. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-30ring: add set_sockopt_tpacket_v3 and refactor othersDaniel Borkmann1-4/+12
Add set_sockopt_tpacket_v3() in preparation for TPACKET_V3. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-30ring: set_sockopt_tpacket: rename to set_sockopt_tpacket_v2Daniel Borkmann1-1/+1
Rename it to set_sockopt_tpacket_v2 so that we later on can also add other versions and have it clearly stated which one we use. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-30ring: remove fanout related bitsDaniel Borkmann1-20/+0
We currently do not support it, so do not keep it here. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-13ring: break out timestamping since not directly relatedDaniel Borkmann1-35/+0
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>
2013-04-23ring: tstamp: no need for tx tsDaniel Borkmann1-1/+1
Set TX timestamping to HWTSTAMP_TX_OFF. We do not use it, therefore do not waist time keeping track of it. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-16ring: don't care if we cannot active hw timestampingDaniel Borkmann1-13/+8
Hw timestaming is currently done, if we have the header file from the kernel available. If it fails, we currently bail out, which is bullshit. Just returning is enough, since some users might have the header available, but not a NIC supporting hw timestaming. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-15all: import netsniff-ng 0.5.8-rc0 sourceDaniel Borkmann1-0/+174
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>
