npftest - a tool for regression testing and debugging NPF.
|
|
It uses RUMP framework to run NPF kernel module in the userspace.
|
|
|

|
|
|
|
Test:
|
|
|
|
npfctl debug npftest.conf /tmp/npf.nvlist
|
|
npftest -c /tmp/npf.nvlist -t
|
|
|
|
Stream:
|
|
|
|
tcpdump -w stream.pcap -i $interface "host $host and tcp"
|
|
npfctl debug npftest.conf /tmp/npf.nvlist
|
|
npftest -c /tmp/npf.nvlist -s stream.pcap > stream_npf_data.txt
|
|
|
|
Preferably, use MALLOC_OPTIONS="AJ" and/or other facilities.
|
|
|
|
Benchmark:
|
|
|
|
npftest -b rule -c /tmp/npf.nvlist -p $ncpu

Update RUMP libraries once the kernel side has been changed. Hint:
|
|
|
|
cd src/sys/net/npf
|
|
sudo make includes
|
|
|
|
cd src/sys/rump/net/lib/libnpf
|
|
make distclean
|
|
MKDEBUG=yes MKDEBUGLIB=yes DBG="-g -O2" make -j8
|
|
sudo MKDEBUG=yes MKDEBUGLIB=yes DBG="-g -O2" make install
