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
