`` The 78 page document outlines 11 knowledge domains, each containing a number of objectives, that form the basis of the certification. The document, a collaborative effort by members of the BSD community, is a followup effort to the BSDP Job Task Analysis report published earlier this year.
"The BSDP Certification Requirements Document provides a comprehensive set of objectives that a BSD Professional should master, ranging from general system administration to advanced security and system maintenance," said Babak Farrokhi, a seasoned BSD administrator and author of 'Network Administration with FreeBSD 7'.
Set to launch in 2011, the BSD Professional certification exam has been in development for over two years. Since the launch of the BSD Associate exam in 2008, there has been a continual effort to put together a certification for the next level of achievement for BSD system administrators.
"The BSD Professional certification is aimed at assessing practical skills of senior level BSD system administrators," said Jim Brown, BSDCG board member. "With the publication of these objectives, the BSD Certification Group is aiming to produce a high quality certification, giving the computing industry a new standard for excellence in system administration."
The BSDP Requirements document is available as a
downloadable PDF in English''
New NetBSD Core Team announced
NetBSD's core team is responsible for technical steering
of the project. In the past the group was five people,
and it was increased to seven people now.
Read more in
Alistair Crooks' announcement:
``We take great pleasure in announcing that the NetBSD core team,
responsible for technical management within the NetBSD project, has
increased its numbers to seven. This is to help in the running of a
project with an ever-growing source base and developer community, and
mirrors a similar change made to the board of directors, which has
worked extremely well.
To help with the running of the project, we have asked Antti Kantee
(pooka%NetBSD.org@localhost) and Chuck Silvers (chs%NetBSD.org@localhost), and
they have
very kindly agreed to join the core team. Antti is well known to many
both inside and outside the project, and has contributed many new and
exciting ideas, the most memorable and useful of these being the rump
kernel architecture. Chuck is also well-known in NetBSD circles - his
work on UBC, and his recent update of the Linux emulation code are
just two examples of his contributions.
We therefore thank them both for their outstanding work to date, and
to their joining the core team to lead and guide progress in the future.
For the current core team:
Alistair Crooks -- agc%NetBSD.org@localhost
Matt Green -- mrg%NetBSD.org@localhost
Antti Kantee -- pooka%NetBSD.org@localhost
Chuck Silvers -- chs%NetBSD.org@localhost
Yamamoto Takashi -- yamt%NetBSD.org@localhost
Matt Thomas -- matt%NetBSD.org@localhost
Christos Zoulas -- christos%NetBSD.org@localhost ''
Of course it runs ... 2.11BSD (or: PDP-11 in a FPGA)
It's about time NetBSD gets the PDP11 port done:
the PDP-11/70 CPU core is now available as implementation on a FPGA-board,
and there's need for a newer operating system than
2.11BSD! Citing from the
homepage:
``The project contains a complete PDP-11 system: a 11/70 CPU with memory management unit, but without floating point unit, a basic set of UNIBUS peripherals (DL11, LP11, PC11, RK11/RK05), and last but not least a cache and memory controllers for SRAM and PSRAM. The design is FPGA proven, runs currently on Digilent S3BOARD and NEXYS2 boards and boots 5th Edition UNIX and 2.11BSD UNIX. ''
Janitorial code maintenance with coccinelle (Updated)
According to its
homepage,
coccinelle is
``a program matching and transformation engine which provides the language SmPL (Semantic Patch Language) for specifying desired matches and transformations in C code. Coccinelle was initially targeted towards performing collateral evolutions in Linux. Such evolutions comprise the changes that are needed in client code in response to evolutions in library APIs, and may include modifications such as renaming a function, adding a function argument whose value is somehow context-dependent, and reorganizing a data structure.''
Jean-Yves Migeon
has applied coccinelle to NetBSD, and suggested performing
two manual tasks, citing from
his email to tech-kern:
replace all sizeof(fooarray)/sizeof(foo) calculations by its
__arraycount() macro equivalent, provided in cdefs.h
detect places where aprint_* calls could
be replaced by aprint_*_dev() to save manual printing of the
device driver's name

Hiding other users' processes
Thus it was asked on #NetBSD:
<batence> I wanna set the top command work only for users process, not
for all system
<batence> in freebsd command is sysctl security.bsd.see_other_uids=0/1
<batence> but I dunno for netbsd
<batence> eg I don't want users see other uids
<batence> only which they owned
Looking at the output of "sysctl -a" didn'r show anything obvious,
but recalling the topic and with some digging, there actually
is a sysctl switch for that in NetBSD: security.models.bsd44.curtain=1
Here's an example top(1) output with the default setting (0).
My username is "feyrer", note that besides my processes,
other users' processes are shown as well:
This reduced set of processes is also shown in ps(1):
% ps -aux | wc -l
7
In other words, only my processes are displayed.
(If you wonder about the difference between the 7 processes shown
in top and the seven ps(1)-lines: the latter includes
a heading).
Note that this "filtering" does not apply to the root
user, i.e. he can still see all processes.

Source-changes ketchup Dec'09 - May'10 [Updated]
Here's what I have in my source-changes folder as interesting
changes between Dec '09 and May '10. YMMV:
NetBSD/cats now uses X.org
NetBSD/sparc64 now runs a MULTIPROCESSOR kernel by default
NetBSD/evbsh3 now also supports the following boards:
AlphaNet MS104-SH4,
TAC T-SH7706LAN Ver.3,
TAC T-SH7706LSR Ver.1
NetBSD/hpcarm now supports the Sharp W-ZERO3 series
wc(1) can print the longest line length now with -L
cdbr(3), cdbw(3) implement constand database reader/writer routines.
this shrinks the services(5) database from 2.1MB to 307kB
/dev/{mem,kmem,zero,null} implementations are unified in machine
independent code on the rmind-uvmplock branch
Many kernel systems were prepared to be built either into a
monolithic kernel, or loaded as module at runtime.
This includes
verbose listing of PCI devices,
Berkeley Packet Filters (bpf),
loading modules only after the root filesystem is mounted,
others.
New drivers:
acpiwmibus: a pseudo-bus to which child Microsoft Windows Management Instrumentation (WMI, a subset of ACPI) devices attach
u2g: split into parts: u3ginit attaches to those devices that only come as a umass device in the default configuration and forces them to reinitialize in 3D mode and detach. The u3g part attaches to individual interfaces for the 3G functionality, leaving the umass interface(s) for that driver. With this change I can use the MMC card in my Huawey stick (as well as the integrated windows driver CD, which of course is pretty useless) and the 3G modem at the same time.
cas: Driver for Sun Cassini/Cassini+ (GigaSwift) Ethernet (also known as National Semiconductor Saturn)
aibs: replaces aiboost for the ASUSTeK AI Booster hardware monitor
NetBSD ketchup - news from my mailbox
Here's another bunch of NetBSD-related news that has
been lingering in my inbox for far too long:
Izumi Tsutsui's
NetBSD/cobalt
restore CD is available based on NetBSD versions
5.0.25.1_RC2.
See the
for information on what it is and how to use it.
A negative symbol lookup cache was added
to NetBSD's loader
for shared libraries and shared objects, ld.so_elf, by
Roy Marples:
``I've been researching why Evolution from GNOME takes over 5 minutes to load on my quad core amd64 beast. It boils down to dlsym looking for a symbol that does not exist directly and as such examining every needed library. However, the current implementation does not remember what libraries it as already checked. Normally this isn't a problem, but with the way Evolution is built the search chain is massive.
[...]
With this patch, Evolution (without the patches to and a glib I added to pkgsrc a few days ago) loads in under 2 seconds (5 seconds with initial disk thrashing). ''
The NetBSD Logo
is available in many variants, but a new variant was submitted
via www@ these days by "Tim" - which is actually plain HTML,
no image:
⚑NetBSD Powered!
SafeNet's ProtectDrive is
``a full disk encryption solution that encrypts the entire hard drive of laptops, workstations and servers, as well as USB flash drives, to protect data in the case of the theft or loss of a hardware device.''
How do you implement such preboot authentication and
harddisk encryption software,
esp. if you want to provide thinks like LDAP integration for
the user/key handling and two-factor authentication?
Little is known, but rumors say the 32bit version of the software
is based on NetBSD, as is backed by
this worker bio info:
``Duties: Working on pre-boot restricted environment with loads before operation system and implemented on NetBSD.
Ported and optimized the KDrive X server to NetBSD.
Developed and implemented user secure authentication interface with smart card support.
Environment and tools : NetBSD (3.0), C/C++, FLTK''
A german-language introduction of pkgsrc on OpenSolaris
was given by Michael 'kvedulv' Moll at the Munich
OpenSolaris User Group back in march.
Slides
and a
video
are available.
Are you still looking for a nice small
ARM-based board to start hacking on NetBSD/arm?
The http://www.friendlyarm.net/products/mini2440
may be a good start, esp. after
Paul Fleischer is reaching completion of NetBSD support
for the board. Citing from
his mail to port-arm:
``I have now fairly good (i.e., it works for me) support for the
MINI2440 on NetBSD with support for the following:
- S3C2440 UART
- DM9000 (MAC+PHY)
- S3C2440 SD Controller
- S3C2440 DMA Controller
- S3C2440 IIS Controller
- FriendlyArm 3,5" LCD Display
- S3C2440 USB Host Controller (OHCI)
- S3C2440 Touch Screen
- UDA1341TS audio codec
Currently, support for three things on the S3C2440 are missing:
- S3C2440 NAND Controller
- S3C2440 USB Device Controller
- S3C2440 RTC
I've also created a stage2 bootloader for use with u-boot, which
ensures that the value of bootargs is passed to the NetBSD kernel.
At this point I have only tested the code with the 64Mb version of the
FriendlyArm MINI2440.
While talking about NetBSD on cool hardware:
How about NetBSD/hpcarm on
WILLCOM | W-ZERO3 (WS004SH) mobile devices?
Here is a screenshot of Ebihara-san's WS011SH with CCW screen,

Apple Magic Mouse driver
NetBSD's Bluetooth hacker #1, Iain Hibbert,
wrote on tech-kern:
``I wrote a driver for the Apple Magic Mouse, as the protocol was mostly
decoded by a Linux developer, and Somebody was kind enough to send me
one. [...]
The mouse itself is a wireless Bluetooth mouse and operates with the USB
HID protocol much like other mice, but it doesn't provide a proper
descriptor and requires features to be activated and special
interpretations of the touch surface reports, so doesn't fit exactly into
our HID framework, which configures independent sub-devices to report id's
from the descriptor.
The driver interprets the touch reports to allow emulation of a middle
mouse button (for mulitple firm touches detected), and horizontal and
vertical scroll actions (for touches moving over a certain distance). It
works well on NetBSD-current and NetBSD-5 and the mouse is pretty slick.
''
See
Iain's posting
for more details.
Silencing the boot process
NetBSD-current is able to boot the userland silently with "boot -z"
for quite some time now, thanks to Alan Barrett.
Those changes were never ported back to the netbsd-5 branch
so far, but I'm in the process to change this now.
Here's a preview:
Of course there are still many places left in the kernel
that don't honor the boot flags (i.e. that use printf(9)
instead of aprint_normal(9) and friends), but this
will change over time - I hope :-).
NetBSD-current build status
Have you ever wondered how stable a -current build is at times?
Here
is an interesting page to give an overview
on the success of NetBSD-current builds from the past few days
(and much further back):
From the webpage:
``This web page visualizes the state of the NetBSD-current build by plotting the number of lines in the build log from build.sh as a function of time, and coloring the points red or green depending on whether the build succeeded or failed. Hopefully, this can help give some insight into the frequency and duration of build failures.
The plots were constructed using an automated procedure that builds NetBSD-current periodically (roughly twice a day) using make.sh -m i386 release, looks for any changes in exit status or any substantial changes in the size of the build log, and then pinpoints the times at which the changes occurred using binary search.
The graph may not contain every build failure, because the algorithm used can miss cases where the build is broken and then fixed again between two consecutive periodic builds. The converse case, when the build is fixed and then broken again between two consecutive periodic builds, is usually detected because the size of the build log usually changes in this case.
Most of the builds in the graph are cross-builds using a 64-bit Linux host, while some of the older ones are native NetBSD builds.

Google Summer of Code 2010 NetBSD swcryptX Project Suggestion (Updated #2) Please see the update below before applying for this
GSoC project!
I've been thinking of a neat-o project for this year's
Google Summer of Code:
Abstract:
The goal of this project is to provide crypto acceleration
by utilizing multiple CPU cores.
The work is to extend the existing software-only "swcrypto"
crypto driver and hook that up with NetBSD's OpenCrypto
framework.
Overview of operation
The opencrypto(9) framework exists to coordinate hardware
acceleration in NetBSD. Applications of the framework can
be inside the kernel like the FAST_IPSEC IPsec implementation,
or in userland like OpenSSL with the "cryptodev" engine.
Crypto drivers can be realized in software or in hardware.
Hardware drivers can be used to instruct e.g. the AMD Geode
LX's AES block or a HIFN chip to perform cryptographic
operations.
Upon system startup, the crypto drivers at the opencrypto(9)
framework, telling what operations they can perform.
When an operation is required later, the framework
will look which crypto device is currently not busy, and
offload the operation to that device.
Upon completion, the result is fed back to the application.
The following image illustrates the components
and their interaction.
Limitations
Offloading the cryptographic requests involves some overhead.
Data needs to be transferred to the hardware and back.
On systems with a slow CPU, this overhead is relatively
small compared to the operation speed of the CPU. On faster
CPUs, the overhead becomes more of a burden, making the
benefit of the crypto hardware negligible.
As examples, while a hifn(4) chip can provide worthwhile
speedups on 500MHz and 1GHz CPUs, no performance
win is experienced on a 2.4GHz CPU.
Proposal
The communication overhead involves data transfers over
a PCI bus, which is of relatively low speed compared
to today's modern CPUs. Preventing the data transfer
is a worthwhile goal. In coordination with today's modern
multi-core CPUs, using one or more CPUs solely for the
purpose of crypto acceleration, a measurable
improvement of crypto performance is expected. At
the same time, no special hardware requirements beyond
the CPU exist. This allows turning standard contemporary
systems into fast crypto systems easily.
The following image illustrates the idea of
interoperation between a CPU core that runs
the kernel and application codes and three
cores that are dedicated to crypto code.
Implementation Roadmap
This is where it gets fishy. ;)
The existing opencrypto(4) framework probably needs to be make
MP-aware at the same time, employing proper use of NetBSD's
locking framework. (Already done)
The existing swcrypto(4) needs to be adjusted for operation on
multiple CPUs at the same time.
A way to decide how many CPUs are dedicated to run swcrypto(4)
instances.
CPUs that run swcrypto(4) need to be taken out from the
usual NetBSD CPU scheduling so that they are available exclusively
for crypto.
Requirements
In no particular order:
Know how to build and install a kernel
Understanding of fine grained SMP and locking
How to use NetBSD's kernel threads, code-wise
How to interact with NetBSD's scheduler, code-wise
Tell the scheduler to pin a specific kernel thread to a
specific CPU
Interaction between applications (IPsec, OpenSSL) with opencrypto(9), code-wise
Interaction of crypto providers with opencrypto(9), code-wise
Hardware! You won't be able to do this without at least two
CPU cores in your machine. The more the better.
If you have any questions let me know, public discussion
should be led on the tech-crypto@ list.
Update:
There was
some discussion.
In particular, my understanding of the interaction of the
various layers as outlined above is not 100% accurate,
and userland applications using opencrypto already seem
to benefit from multiple kernel threads.
In-kernel applications apparently do not, and before
providing multiple crypto-servers in kernel (as suggested),
work should probably done first to make sure such
applications exist. Examples of this are IPsec (and the whole
network stack), but also others like cgd (which AFAIU currently
does not use opencrypto(9)).
