Catching up on source-changes (Feb 21st - Mar 1st)
Mark Kirby's CVS digest is still down. I'd love for someone to continue this service - please
contact Mark and/or me for details! (I don't really have time to do this,
but will try to do so. Help is definitely appreciated!!!)
Catching up on NetBSD's
source-changes mailing list from
Feb 21st 2008 to Mar 1st 2008, here's what people not following
things closely may find interesting:
- Chris Gilbert made process on the chris-arm-intr-rework
branch, which aims at reworking the ARM interrupt code to provide
a shared set of interrupt routines that can be used across
all ARM based machines.
- The PowerPC routines for bcopy, memcmp, memcpy and memmove were
updated to use tuned versions that were written by IBM and released
under a 3-clause BSD license as part of the perflib project, see
http://sourceforge.net/projects/ppcperflib/.
- Keiichi Shima has imported the Mobile IPv6 code developed by
the SHISA project. The
work can be found on the "keiichi-mipv6" branch.
- Matt fleming has started work on a device file system that supports
dynamic device nodes, which is of relevance when loading kernel
modules for device drivers, so you don't have to run /dev/MAKEDEV
manually. The work is on the "mjf-devfs2" branch.
- Nick Hudson is currently working on syncing NetBSD's WiFi (net80211)
code with FreeBSD, so that these two operating systems (and possibly
others) can share a common codebase. The work currently affects
only the kernel, but this may extend to the userland eventually.
- The glob(3) wildcard extension routines got a new options
GLOB_NO_DOTDIRS added, which hides . and .. even if the pattern
would otherwise include them.
- Juan Romero Pardines has ported the mfi(4) driver from OpenBSD. The
driver supports disk controllers with PowerPC IOSs such as the LSI
SAS1078 and the Dell PERC6.
- The boot-only ISOs built for releases included several kernels
(with ACPI, without ACPI) for some time now. Stephen Borrill has
added a menu to make kernel selection easier. Mmm, user friendliness!
- The machine-independent versions of strcspn(3), strpbrk(3) and
strpspn(3) were improved from O(mn) to O(n+m) based on ideas from
DragonFlyBSD.
- Power management hooks for suspend, shutdown and resume were
added to many device drivers, to support the new power management
framework by Jared McNeill.
- A whole lot of changes were pulled up from NetBSD's development
branch into the release branches for NetBSD 3.x and 4.x.
So much for this round of updates. A lot of work was not done on the
main trunk but on some branches. People interested to learn what branches
exist in NetBSD's source tree can check out src/doc/BRANCHES to do so.
Enjoy!

Mondo catch-up on source-changes (~Aug '07 'till Feb '08)
In the context of Mark Kirby
stopping his NetBSD CVS Digest,
I've felt an urge to catch up on
source-changes, and put
up some of the items here that I haven't found mentioned
or announced elsewhere (or that I've plainly missed)
after digging through some 7,000 mails. All those
changes are
available in NetBSD-current today
and that will be in NetBSD 5.0:
- Support C99 complex arithmetic was added by importing the
"cephes" math library
- POSIX Message queues were added
- bozohttpd was added as httpd.
- the x86 bootloader now reads /boot.cfg to configure banner
text, console device, timeout etc. - see boot.cfg(5)
- ifconfig(8) now has a "list scan" command to scan for access points
- SMP (multiprocessor) support is now enabled in i386 and amd64 GENERIC kernels
- Processor-sets, affinity and POSIX real-time extensions were added,
along with the schedctl(8) program to control scheduling of processes
and threads.
- systrace was removed, due to security concerns
- the refuse-based Internet Access Node file system was committed, which
provides a filesystem interface to FTP and HTTP, similar to the old
alex file system,
see http://mail-index.netbsd.org/source-changes/2007/08/28/0081.html
- LKMs don't care for options MULTIPROCESSOR and LOCKDEBUG, i.e.
it's easier to reuse LKMs between debugging/SMP and non-debugging/SMP
kernels now.
- PCC, the Portable C Compiler that originates in the very beginnings of
Unix, was added to NetBSD. The idea is that it is used as alternative
to the GNU C Compiler in the long run.
- In addition to the iSCSI target (server) code that is already in
NetBSD 4.0, there'a also a refuse-based iSCSI initiator (client)
now, see http://mail-index.netbsd.org/source-changes/2007/11/08/0038.html
Plus:
- Many driver updates and new drivers, see your nearest GENERIC kernel config file
- Many security updates, see list of security advisories
- Many 3rd software packages that NetBSD ships with were updated:
ipsec-tools (racoon), GCC 4.1, Automated Testing Framework 0.4,
OpenSSH 4.7, wpa_supplicant and hostapd 0.6.2, OpenPAM Hydrangea
The above list is a mixed list of items. There are a number of
areas where there is very active development going on in NetBSD.
Andrew Doran is further working on SMP, fine-grained locking
inside the kernel and interrupt priority handling. Antti Kantee
has has done more work on his filesystems work (rump, puffs,
refuse/fuse), and Jared McNeill and Jörg Sonnenberger have
continued their work on NetBSD's power management framework.
Those changes are large and far-reaching, and I've yet to look
at them before I can report more here.
So much on this subject for now. If someone's willing to help out
with continuing Mark Kirby's
NetBSD CVS Digest
either using his software-setup or by simply reading the list
and writing a monthly/weekly digest of the "interesting" changes,
I'd appreciate this very much. Put me on CC: for your postings! :)

Big 2005 catch-up
OK, due to moving back to Germany (I'll stay here, btw, the time in the
US was just a temporary, 1-time thing, FYI) and some other action at the
end of the year, I haven't had time to put stuff in here, but I still
have quite a backlog of stuff from late 2005 that I think should be
mentioned here. Instead of trying to make individual entries for
them, I've decided to be lazy and lump them all into one entry.
Here we go!
- There was a discussion recently that (old, pre-ANSI) style C
function definitions are harmful and thus deprecated.
After some attempts to come up with an example that shows
the problem,
Greg Troxel came up with a working one.
Key here is that on 64bit platforms, parameters that can't be passed
in registers (due to not enough registers), i.e. for functions with
a lot of parameters, the K&R style prototypes may wrongly assume
a type is "int" (==32bit, even on LP64 platforms), and thus be wrong.
See Greg's mail including example output and some analysis.
- There's a nice article Inside NetBSD's CGD
on O'Reilly's OnLAMP where CGD-author Roland Dowdeswell talks about
CGD, its use, implementation details and a comparison against
other, similar projects.
- I usually don't link to articles that claim that software XXX
(e.g. the GNU Telephony Stack)
also runs on NetBSD,
but saying that ``Currently Boost comes bundled with Fedora, Debian, and NetBSD''
seems wrong enough to state here that Boost is not part
of the NetBSD base system. Boost is available via pkgsrc, though.
- Yeah, NetBSD 3.0 was released, mentioned at least on
Slashdot,
ZDNet UK,
Heise
and
TechSpot.
Old news by now, but still good to waste some time reading the
troll postings on a slow new-year's day. :)
- I found a bunch of nice
Daemon pix
(which I've just synced with my own
collection yet)
- While there is no (publically available...) iSCSI implementation
available for NetBSD natively, Al Crooks
writes
that people can try
``pkgsrc/devel/intel-iscsi, which is Intel's reference
iSCSI target ported to NetBSD, and there's a userlevel iSCSI initiator
in there too, for testing purposes. The package also has the other
half of the equation, an OSD target.''.
Who's first to write some iSCSI instructions for NetBSD?
Reports of success or failure? :)
- pkgsrc was branched for the pkgsrc-2005Q4 branch,
see the announcement
- Issue 38 of the NetBSD CVS Digest is out
- The NetBSD kernel is usually loaded by a bootloader. In that process,
the bootloader passes a few bits of information (boot to singleuser
mode, where the kernel was loaded from to find the root filesystem,
...) on to the kernel. That interface is very NetBSD specific
and different from those used by other systems (which are mostly
specific to those systems). GRUB has set some standard that's used
by (surprise) Linux and more recently OpenSolaris, and now
Julio Merino Vidal has been working on making a NetBSD kernel
understand the "Multiboot" protocol as an alternative to NetBSD's
own bootloader. While GRUB always worked to boot NetBSD, some
parameters (e.g. the root filesystem) were not passed on properly.
See Julio's mail for a lot more details!
- Status of NDIS integration for NetBSD: Alan Ritter
has worked on an interface to use Microsoft Windows network drivers
following the NDIS specification in NetBSD as part of the
Google Summer of Code project. He has posted a
status update
on the integration of his work into NetBSD.
- Jan Schauman has uploaded pkgsrc-2005Q4 3.0/amd64 binary packages.
I'm still waiting for Manuel's 3.0/i386 pkgs... :)
- Work is underway to get a
NetBSD 3.0 cobalt restore CD
So much for now. In the mean time I've also done some work
on updating qemu 0.8.0 and collecting what communication-exec did
in 2005 for an internal status report, but that's something
for future updates.
