2013-06-04corking: break out udp/tcp cork functionsDaniel Borkmann1-52/+0
No, it's not about whine bottles ... move udp and tcp cork functions out of xutils.c, so that we can further let it shrink. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04cpus: break out cpu related functions from xutilsDaniel Borkmann1-10/+0
Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04xutils: break out string handling and lockingDaniel Borkmann1-88/+1
Break out all string handling functions and lockme stuff in order to further eliminate the big code blob in xutils, so that it can be easier maintained. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-03iosched: break out io scheduling functions from xutilsDaniel Borkmann1-59/+0
Break this stuff out, for better maintainability and readability. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-03netsniff-ng: v3: fix packet accounting on --numDaniel Borkmann1-22/+0
We need to carry frame_count through multiple calls of walk function to account correctly for --num <pkts>. Also, move socket stats printing into rx ring, since it belongs there. Todo: the kernel socket seems to have a different count that what we see. This needs to be fixed one way or the other. Not yet sure what's causing this.

2013-06-03irq: break out from xutils and save + restoreDaniel Borkmann1-108/+0
Break out IRQ functionality from xutils, simplify it, and save + restore IRQ affinity list. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-31ring: netsniff-ng: migrate capture only to TPACKET_V3Daniel Borkmann1-4/+5
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>
2013-05-12xutils: Make set_nonblocking() voidTobias Klauser1-3/+1
The return values is always 0 and it is never checked anyhow, so make the function void. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-03-16xutils: check various return valuesDaniel Borkmann1-14/+35
Check various setsockopt return values and exit accordingly if some of them just fuck up. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-15all: import netsniff-ng 0.5.8-rc0 sourceDaniel Borkmann1-0/+1024
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>
