- Designed to be fully MP-safe and highly efficient.
- Tables/IP sets (hash or red-black tree) for high performance lookups.
- Stateful filtering and Network Address Port Translation (NAPT).
Framework for application level gateways (ALGs).
- Packet inspection engine called n-code processor - inspired by BPF -
supporting generic RISC-like and specific CISC-like instructions for
common patterns (e.g. IPv4 address matching). See npf_ncode(9) manual.
- Convenient userland utility npfctl(8) with npf.conf(8).
NOTE: This is not yet a fully capable alternative to PF or IPFilter.
Further work (support for binat/rdr, return-rst/return-icmp, common ALGs,
state saving/restoring, logging, etc) is in progress.
Thanks a lot to Matt Thomas for various useful comments and code review.

It offer the following subcommands:
list - shows all child codec
get - get a plist of the chosen codec's widget configuration
set - forcibly reconfigure a specified codec from a plist
graph - generate a graphviz file for the specified codec
ethernet, allowing machines to be powered up without physical access to them.
tonnerre@ and tron@ reviewed it and decided that the bin directories
are not to full for this small and useful command.
ddb running on crash dumps, but with two notable changes:
- Breakpoints, watches, etc are obviously never going to work so they
are not handled.
- You can pipe output to the shell, e.g. ps | grep foo
Items remaining to be done:
- Port it to architectures other than i386. This isn't difficult, just
a case of making db_disasm.c/db_trace.c or their equivalent compile
and work.
- Make more of the "show" commands work, e.g "show uvmexp".
and DVD's behave like floppy discs. Writing is supported upto and including
version 2.01; version 2.50 and 2.60 will follow.
Also extending the UDF implementation to support symbolic links and
hardlinks.
Added are the mmcformat(8) tool to format rewritable CD/DVD discs and
newfs_udf(8).
Limitations:
all operations can be performed on the file system though the
sheduling is currently optimised for archiving workloads.
mv(1)/rename(2) is currently only implemented for non-directories.
btuartd(8) should be named btattach(8) for consistency
with other parts of NetBSD
make btattach(8) a single-use tool for less complexity
device specicific initialisation (from btuart(4)) is carried
out prior to activating the line discipline (in btattach(8)),
which simplifies the API somewhat and means that the user
tool and the kernel do not need to be kept in sync.
btuart(4) driver is much reduced; naming is made consistent
and all tsleep() and delay() are removed to userland
Add schedctl(8) - a program to control scheduling of processes and threads.
Notes:
- This is supported only by SCHED_M2;
- Migration of LWP mechanism will be revisited;

This one has some nice options -- for example, an admin can run right
after installing a system:
fpgen -D
and it will fingerprint a set of "common" system directories to the
default loaction. See the man-page for more stuff.
Performance-wise, here are results for both fpgen.sh (old) and this
new tool:
474.599u 574.335s 13:53.05 125.9% 0+0k 0+307io 0pf+0w
0.424u 0.131s 0:00.56 98.2% 0+0k 0+2io 0pf+0w
...guess which is which? (that's ~1500 times *faster*)
NetBSD Foundation Membership still pending.) This stack was written by
Iain under sponsorship from Itronix Inc.
The stack includes support for rfcomm networking (networking via your
bluetooth enabled cell phone), hid devices (keyboards/mice), and headsets.
Drivers for both PCMCIA and USB bluetooth controllers are included.
1. Removed the makeoptions line from arch/i386/conf/GENERIC. Now
ndis_driver_data.h is simply copied into the kernel build directory instead
of editing the config file to specify its location.
2. Uncommented lines in files.i386 and files.pci related to NDIS. NDIS will
not be compiled into the kernel unless the two lines are uncommented from
GENERIC (I checked using nm), so there is no reason for this to be commented
out.
3. Added ndiscvt to usr.sbin/Makefile.
backing file per attribute type indexed by inode number to hold the extended
attributes.
This is working pretty well on my test systems, except for the "autostart"
feature. I need someone with a better handle on the VFS locking protocol
to go over that.
This is a work-in-progress. There are parts of this that could be re-factored
allowing this approach to be used on other types of file systems.
