- 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 will replace azalia(4) after testing.
To use, comment out azalia in your kernel configuration and uncomment the
hdaudio and hdafg lines so it reads:
# Intel High Definition Audio
hdaudio* at pci? dev ? function ?
hdafg* at hdaudiobus?
You should also:
cd /dev
sh MAKEDEV audio
the base NetBSD system. It uses Linux LVM2 tools and our BSD licensed
device-mapper driver.
The device-mapper driver can be used to create virtual block devices which
maps virtual blocks to real with target mapping called target. Currently
these targets are available a linear, zero, error and a snapshot (this is
work in progress and doesn't work yet).
The lvm2tools adds lvm and dmsetup binary to based system, where the lvm
tool is used to manage and administer whole LVM and the dmestup is used to
communicate iwith device-mapper kernel driver. With these tools also
a libdevmapper library is instaled to the base system.
Building of tools and driver is currently disable and can be enabled with
MKLVM=yes in mk.conf. I will add sets lists and rc.d script soon.

"retro" computers, but NetBSD also runs a growing number of rare
and retro add-on cards. With this patch, NetBSD supports the IDEC
Supervision/16, a black&white image capture board for the 16-bit
ISA bus. Approximate date of manufacture: 1991. Total instances
known to be in use throughout the world: one.

via the standard audio interfaces is redirected back to userland as raw
PCM data on /dev/padN.
One example usage is to stream audio to an AirTunes compatible device using
rtunes (http://www.nazgul.ch/dev_rtunes.html), ie:
$ rtunes - < /dev/pad0
$ mpg123 -a /dev/sound1 blah.mp3
Another option is to capture audio output from eg. Real Player, by simply
instructing Real Player to output to /dev/sound1, and running:
$ cat /dev/pad0 > blah.pcm
Rip the transport code completely out of puffs and generalize it
into an independent module which will be used for multiple purposes
in the future. This module is called the Pass-to-Userspace
Transporter (known as "putter" among friends).
This is very much work-in-progress and one dependency with puffs
remains: the request framing format.
The device name is still /dev/puffs, but that will change soon.
Users of puffs need the following in their kernel configs now:
pseudo-device putter
device controllers, and more specifically raid controllers.
Add a new sensor type, ENVSYS_DRIVE, to report drive status. From OpenBSD.
Add bio and sysmon support to mfi(4). This allow userland to query
status for drives and logical volumes attached to a mfi(4) controller. While
there fix some debug printfs in mfi so they compile.
Add bio(4) to amd64 and i386 GENERIC.

add bthub(4) which autoconfigures at bluetooth controllers as they

btdevctl(8) and its cache is updated to handle new semantics

Change the way in which bluetooth devices attach to system. The
new way is for devices to attach directly to a btdevN device via
its own control file /dev/btdevN.
- bthub(4) is replaced by btdev(4).
- /dev/bthubctl is replaced by /dev/btdevN.

Add a amrctl(8) control tool, which for now only allows to get status

These devices have a USB client port which can be used to upload and
download recordings (and other files, such as MIPS binaries for execution
on the DVR's CPU) to/from their internal hard disk, in addition to some
other operations on files and directories.
NAME
tap - virtual Ethernet device
SYNOPSIS
pseudo-device tap
DESCRIPTION
The tap driver allows the creation and use of virtual Ethernet devices.
Those interfaces appear just as any real Ethernet NIC to the kernel, but
can also be accessed by userland through a character device node in order
to read frames being sent by the system or to inject frames.
In that respect it is very similar to what tun(4) provides, but the added
Ethernet layer allows easy integration with machine emulators or virtual
Ethernet networks through the use of bridge(4) with tunneling.
``Qui tacet consentire videtur.''
clients, and a pseudo-device for userspace access.
The attribute is named `opencrypto'. The pseudo-device is renamed to
"crypto", which has a dependency on "opencrypto". The sys/conf/majors
entry and pseudo-device attach entrypoint are updated to match the
new pseudo-device name.
Fast IPsec (sys/netipsec/files.ipsec) now lists a dependency on the
"opencrypto" attribute. Drivers for crypto accelerators (ubsec,
hifn775x) also pull in opencrypto, as providers of opencrypto transforms.
Uses a hook in spec_strategy() to save data written from a mounted
file system to its block device and a hook in dounmount().
Not enabled by default in any kernel config.
