2020-10-02all: change bug report instructions in copyright messageTobias Klauser1-1/+2
The bugs@netsniff-ng.org e-mail bounces. Also it's more convenient to report bugs using GitHub rather than via e-mail, so consistently mention https://github.com/netsniff-ng/netsniff-ng/issues for where to report bugs. Fixes #226 Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2016-12-10bpfc: make verbose parameter booleanTobias Klauser1-4/+4
Verbose mode is a boolean option, so make the variable and parameters carrying it of type bool. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2016-12-08all: Remove unused longindex parameter to getopt_long()Tobias Klauser1-3/+3
All tools (except mausezahn) use getopt_long() and pass a pointer to a local opt_index variable for the longindex parameter. However, this variable is never read afterwards. According to getopt(3) it's perfectly fine to pass NULL as the longindex parameter instead, so do that. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2015-12-17bpfc: Add option to pass macro/define for C preprocessorVadim Kochan1-3/+13
Add -D,--define option to pass macro/define for C preprocessor (e.g. to use #ifdef's within bpf file). Option allows to pass multiple -D,--define options. Signed-off-by: Vadim Kochan <vadim4j@gmail.com>
2015-10-28all: Change reporting bugs emailVadim Kochan1-1/+1
Replace bugs@netsniff-ng.com with netsniff-ng@googlegroups.com which is used in REPORTING-BUGS file. Signed-off-by: Vadim Kochan <vadim4j@gmail.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-12-12all: Reduce amount of empty liens in usage and version output a bitTobias Klauser1-5/+5
No need for some of the empty lines, remove them to make the output a bit denser. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2014-09-05bpfc: Don't duplicate copyright/bug report/license stringTobias Klauser1-14/+11
Move the copyright/bug report/license string to an own constant and use it for the output of help() and version() to avoid duplication and prevent the strings from getting out of sync. This makes the text section of bpfc.o slightly smaller: before: text data bss dec hex filename 3594 0 0 3594 e0a bpfc/bpfc.o after: text data bss dec hex filename 3313 0 0 3313 cf1 bpfc/bpfc.o Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-10-11bpfc: alias xt_bpf to tcDaniel Borkmann1-2/+3
Alias output format for tc/xt_bpf. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-07-09all: show git id in --version informationDaniel Borkmann1-2/+4
In order to be able to better track regressions or to give support, let us track the Git id as well in version information. This makes the ``--version'' switch actually useful. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-15bpfc: stress that also seccomp-BPF can be generated with bpfcDaniel Borkmann1-1/+3
Just add a minor sentence to help stating this. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-06-04xutils: eliminate xutils, move rest to epoll2Daniel Borkmann1-1/+1
Finally eliminate xutils.{c,h} and move the rest to epoll2. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-23make: include build nameDaniel Borkmann1-1/+1
Include long version string into tools when called with --version. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-23bpfc: minor: do a line-break before 80-columnDaniel Borkmann1-1/+2
Just a minor cosmetic fix. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-23bpfc: allow bpf programs to be passed to cppDaniel Borkmann1-4/+10
This patch allows bpf programs to be passed to the C preprocessor before handing over to bpfc. Example: #define ETH_P_IP 0x800 ldh [12] jne #ETH_P_IP, drop ldb [23] jneq #6, drop ldh [20] jset #0x1fff, drop ldxb 4 * ([14] & 0xf) ldh [x + 14] jeq #0x16, pass ldh [x + 16] jne #0x16, drop pass: ret #-1 drop: ret #0 Compile with: bpfc -i foo -p Suggested-by: John Lange <JLange@trendium.com> Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-05-17bpfc: Add __noreturn attribute to exiting functionsTobias Klauser1-2/+2
Add the __noreturn attribute to all functions which wont return but call die() themselves to exit(). Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-05-15man: trafgen: Minor fixesTobias Klauser1-2/+2
Replace "on default" by "by default", make it a bit more clear what the seed in the -E/--seed option is for and mention exit after display of information on --version and --help. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
2013-03-16bpfc: support different output formatsDaniel Borkmann1-10/+22
Add different bpf opcode pretty printer to support a variety of output formats for netsniff-ng, xt_bpf, tcpdump, C-like and make future integration of formats easier. Signed-off-by: Daniel Borkmann <dborkman@redhat.com>
2013-03-15all: import netsniff-ng 0.5.8-rc0 sourceDaniel Borkmann1-0/+132
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>
