2013-03-26trafgen: update help descriptionDaniel Borkmann1-0/+1
After commit f9591eebe40c (trafgen: lexer/parser: fix cpu() selection and whitespacing), we also need to fixup the help description, so that users start using the cpu(X-Y) notation instead. Also, reintroduce the alias csum16 for csumip. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-25trafgen: lexer/parser: fix cpu() selection and whitespacingDaniel Borkmann1-2/+2
It looks unintuitive when once needs to write cpu(0:3), so also allow cpu(0-3). Then it's quite stupid to enforce whitespace after the double colon before the curley braces open. So make this rather optional here. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-16trafgen: add csumicmp for ICMP checksum calculationDaniel Borkmann1-0/+2
Both, the IP and ICMP checksums use the same algorithm from RFC1071. Thus, it's enough if we give csumip an alias to csumicmp, so that it can be used in trafgen packet configurations. It's calculated from the ICMP header + data, with value 0 for this field. Suggested-by: Jon Schipp <jonschipp@gmail.com> Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-15all: import netsniff-ng 0.5.8-rc0 sourceDaniel Borkmann1-0/+152
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>
