rmind 3107fd1eb5 - nbuf_ensure_contig: rework to use m_ensure_contig(9), which will not free the mbuf chain on failure. Fixes some corner cases. Improve regression test and sprinkle some asserts. - npf_reassembly: clear nbuf on IPv6 reassembly failure path (partial fix). The problem was found and fix provided by Anthony Mallet.		2013-01-20 18:45:56 +00:00

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.plist
npftest -c /tmp/npf.plist -t

Stream:

tcpdump -w stream.pcap -i $INTERFACE "host $HOST and tcp"
npfctl debug
npftest -c /tmp/npf.plist -s stream.pcap -o stream_npf_data.txt

---

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
