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.
Also, I would like to thank Gateworks Corporation for sending me a
Cambria board which was used during the development of this project.

- creation of sparse files to speed up the build process. This was
discussed with phk 2 years ago and he disagreed with this change.
- handling of negative data partition sizes.
Can I have the ... green pointy hat, please?
- buildworld and buildkernel are built into MAKEOBJDIRPREFIX
- installworld and installkernel are performed on NANO_OBJ.
No change of functionality if MAKEOBJDIRPREFIX is not set. If it is sea,t
clean_world deletes NANO_OBJ instead of NANO_WORLDDIR. By starting nanobsd.sh
with the -b option the existing world can be reused to build a new world
reducing time and disk space considerably.
While there:
- Fix two cases where (in comments) MAKEOBJDIRPREFIX should have been
NANO_DISKIMGDIR.
- Simplify an 'if (not wrong); then true; else action; fi' into
'if wrong; then action; fi'. 'if ! false; then echo hello; fi' produces hello.
Note: Make sure you use NANO_OBJ were you use MAKEOBJDIRPREFIX now in your
nanobsd.conf files if you want to split out.
number.
It is possible to ask nanobsd.sh to create a 'data' partition,
separate from the system or configuration partitions, and
furthermore, by specifying a negative value for its size
to request that it use all space unused by those partitions
for its own size.
Because the two lines of code that calculate how much space
is available for this data partition are written in perl-like
syntax, the awk code that does the processing performs the
calculation incorrectly.
[note - this was already fixed by r174936]
Furthermore, a comparison later down fails to newfs the
partition when the size is negative.

This patch against RELENG_6 adds two more entries to
src/tools/tools/nanobsd/FlashDevice.sub - one for a 256MB
Hitachi CF card and one for a 256MB Silicon Systems CF card.
Both entries have been verified to work with a Soekris net4801.

any open file descriptors >= 'lowfd'. It is largely identical to the same
function on other operating systems such as Solaris, DFly, NetBSD, and
OpenBSD. One difference from other *BSD is that this closefrom() does not
fail with any errors. In practice, while the manpages for NetBSD and
OpenBSD claim that they return EINTR, they ignore internal errors from
close() and never return EINTR. DFly does return EINTR, but for the common
use case (closing fd's prior to execve()), the caller really wants all
fd's closed and returning EINTR just forces callers to call closefrom() in
a loop until it stops failing.
Note that this implementation of closefrom(2) does not make any effort to
resolve userland races with open(2) in other threads. As such, it is not
multithread safe.

I found out that the input format of the Boemler list was different
than what the code expected: The last two fields were interpreted
as one. Checking the csv version of the list it showed that there
was sometimes a chipset number in the column before the card
description.
This is a rewrite to use the CSV format of the Boemler list. The
output is differently formatted: Instead of the "chip description",
it is now "description (chip)"
