2013-05-10make: allow to overwrite CFLAGS, CCACHEDaniel Borkmann1-3/+3
Allow to define custom compile flags, e.g. ... make CFLAGS="-O2 -Wall" ... and also allow to overwrite ccache variable: make CCACHE= all Also do some minor fixes when built with -O2 -Wall. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-10pcap_io: minor: fix some quirksDaniel Borkmann1-3/+3
We can just replace int with uin32_t, that's no problem. Also fix one case where we moved to uint16_t. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-10pcap: let netsniff-ng also record pkt timestamp sourceDaniel Borkmann1-3/+26
With commit [1] in the kernel, we can also store the timestamp source in the pcap packet header for later analysis. We do this by splitting the netsniff-ng's u32 ifindex into u16 tsource and u16 ifindex. Older kernel do not support the timestamp source in PF_PACKET, so it will stay 0 and is compatible with older netsniff-ng binaries.

2013-04-09pcap_io: introduce init_once helper that is called with priviledgesDaniel Borkmann1-0/+1
When using netsniff-ng with dropping priviledges, we have to introduce another pcap helper function that is called once before we drop the priviledges. In this function we have to invoke the disc I/O scheduler policy, because it needs priviledges. Otherwise netsniff-ng will fail with "Failed to set io prio for pid" on startup, since we're not root anymore.

2013-03-15all: import netsniff-ng 0.5.8-rc0 sourceDaniel Borkmann1-0/+581
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>
