Clean up the ttys files shipped with PicoBSD, NanoBSD and TinyBSD. While
there, it seems one of them still had references to sio(4). Make it in
sync with what we do in the base system.
Right now syscons(4) uses a cons25-style terminal emulator. The
disadvantages of that are:
- Little compatibility with embedded devices with serial interfaces.
- Bad bandwidth efficiency, mainly because of the lack of scrolling
regions.
- A very hard transition path to support for modern character sets like
UTF-8.
Our terminal emulation library, libteken, has been supporting
xterm-style terminal emulation for months, so flip the switch and make
everyone use an xterm-style console driver.
I still have to enable this on i386. Right now pc98 and i386 share the
same /etc/ttys file. I'm not going to switch pc98, because it uses its
own Kanji-capable cons25 emulator.
IMPORTANT: What to do if things go wrong (i.e. graphical artifacts):
- Run the application inside script(1), try to reduce the problem and
send me the log file.
- In the mean time, you can run `vidcontrol -T cons25' and `export
TERM=cons25' so you can run applications the same way you did before.
You can also build your kernel with `options TEKEN_CONS25' to make all
virtual terminals use the cons25 emulator by default.

netsend 127.0.0.1 6666-7777 [payloadsize] [packet_rate] [duration]
This is useful to test the behaviour of systems that do some kind
of flow classifications and so exhibit different behaviour depending
on the number of flows that hit them.
I plan to add a similar extension to sweep on a range of IP addresses,
so we can issue a single command to flood (obviously, for testing
purposes!) a number of different destinations.
When there is only one destination, we do a preliminary connect()
of the socket so we can use send() instead of sendto().
When we have multiple ports, the socket is not connect()'ed and we
do a sendto() instead. There is a performance hit in this case,
as the throughput on the loopback interface (with a firewall rule
that blocks the transmission) goes down from 900kpps to 490kpps on
my test machine.
If the number of different destinations is limited, one option to
explore is to have multiple connect()ed sockets.

I found out that on many machines round here, i could only get
300-400kpps with netsend even on loopback and a 'deny' rule in
the firewall, while reducing the number of calls to gettimeofday()
brings the value to 900kpps and more.
This code is just a quick fix for the problem. Of course it could be
done better, with proper getopt() parsing and the like, but since
this applies to the entire program i'll postpone that to when i have

network stack instances, which is provided for compatibility with

to the initial conversion of vimage to use the new jail(4)
userland-kernel API:
- when creating vimages via "vimage -c", by default turn on a few
options expected by legacy applications, such as allow operations on
raw sockets, FS mounts etc, and allow jail-related parameters to be
optionally configured.
- introduce the "-m" modifier which allows for configuring jail
parameters of existing vimages / vnet-jails.
- make "vimage name command ..." actually work.
- when reassigning ifnets to vnets using "vimage -i", attempt to rename
the ifnet as "ethXXX" on arrival in the target vnet. Several legacy
applications are known to depend heavily on such behavior.
- vimage -l lists only jails associated with vnets. The output is
sorted using vimage / jail names as keys.
- vimage -l by default searches only the current level in the jail
hierarchy. Recursive listing can be requested via -r switch.
- vimage -l by default prints only jail names on each line, making
such output suitable for pipelining to other commands. More verbose
output can be obtained via -v switch, and even more jail specific
information will be displayed if -j switch is turned on.
- there's no need to build vimage as statically linked, so update the
Makefile accordingly.
- update the vimage.8 man page.

net80211 wireless stack. This work is based on the March 2009 D3.0 draft
standard. This standard is expected to become final next year.
This includes two main net80211 modules, ieee80211_mesh.c
which deals with peer link management, link metric calculation,
routing table control and mesh configuration and ieee80211_hwmp.c
which deals with the actually routing process on the mesh network.
HWMP is the mandatory routing protocol on by the mesh standard, but
others, such as RA-OLSR, can be implemented.
Authentication and encryption are not implemented.
There are several scripts under tools/tools/net80211/scripts that can be
used to test different mesh network topologies and they also teach you
how to setup a mesh vap (for the impatient: ifconfig wlan0 create
wlandev ... wlanmode mesh).
A new build option is available: IEEE80211_SUPPORT_MESH and it's enabled
by default on GENERIC kernels for i386, amd64, sparc64 and pc98.
Drivers that support mesh networks right now are: ath, ral and mwl.
More information at: http://wiki.freebsd.org/WifiMesh
Please note that this work is experimental. Also, please note that
bridging a mesh vap with another network interface is not yet supported.
Many thanks to the FreeBSD Foundation for sponsoring this project and to
Sam Leffler for his support.

avoid problems from reusing 4-tuples too quickly. Aggregate bandwidth use

I have been running -current on my laptop since before FreeBSD 2.0 was
released and along the way developed this little trick to making the
task easier.
sysbuild.sh is a way to build a new FreeBSD system on a computer from
a specification, while leaving the current installation intact.
sysbuild.sh assume you have two partitions that can hold your rootfs
and can be booted, and roughly speaking, all it does is build a new
system into the one you don't use, from the one you do use.
A partition named /freebsd is assumed to be part of your layout, and
that is where the sources and ports will be found.
If you know how nanobsd works, you will find a lot of similarity.

o add minor bits to user tools that need to know: ifconfig to setup and
configure, new statistics in athstats, and new debug mask bits
While the architecture can support >2 slots in a TDMA BSS the current

This includes introducing a function pci_find_dbsf(9) which works
like pci_find_bsf(9) but additionally takes a domain number argument
and limiting pci_find_bsf(9) to only search devices in domain 0 (the
only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are
changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order
to no longer report false positives when searching for siblings and
dupe devices in the same domain respectively.
Along with this change the sole host-PCI bridge driver converted to
actually make use of PCI domain support is uninorth(4), the others
continue to use domain 0 only for now and need to be converted as
appropriate later on.
Note that this means that the format of the location strings as used
