[20161030] NetBSD 7.0.2 released
Why 7.0.2? Following NetBSD's release scheme, there are major releases (e.g. 7.0) with subsequent updates (e.g. 7.1). Those "major" release and their updates include both new features as well as bug fixes - the latter one again with and without security relevance. New code, new risks - as a result for getting updates, existing interfaces may change and lead to incompatibiltites. This may affect either binary compatibility between programs and their required shared libraries, as well - though rare - incompatible chances on the source code level.

NetBSD takes quite some effort to keep such incompatibilites low, yet they happen. The only real solutions is: no updates. "Never change a running system" is nice for availability, but it poses security risks. The time when a big server uptime was considered a sign of good system administration are gone. Today, a long update means the system (probably) runs outdated and as such vulnerable code.

So to solve the problem a compromise is needed: little updates, but crucial security updates do get done. Which is where NetBSD's "minor" release like NetBSD 7.0.2 come into play. With its set of changes, a number of external software packages got security-related updates (e.g. OpenSSL, NTP, BIND, X), and a smaller number of security related changes were also added, e.g. a race condition in mail.local(8), crashes in the Networking File System (NFS) and the native Fast File System (FFS) plus some platform-specific crashes on MIPS, PowerPC and SPARC64.

For more information on downloading and installation see the release announcement as well as the platform-specific install documentation, e.g. for NetBSD 7.0.2/arm64's INSTALL.html file.

[20060302] Atheros ath* wlan now available for NetBSD/sparc64
The Atheros ath(4) driver is an interesting piece of software, consisting of a .c glue file that calls into a binary blob object file. While the interface to the blob is known, the internal details of it are not, and the blob does all the talking to the actual hardware. To port the ath(4) driver to a new platform, a compiled version of that binary blog is necessary, obviously. Also, some adjusting is needed to adjust the C interface file to existing blobs to maintain compatibility with the operating systems' interface.

Now, Martin Husemann has fixed up the glue layer to work on NetBSD/sparc64, see his mail for more details.

(Some people may wonder now why all that fuzz is needed: Atheros doesn't make the sources of the binary blob available for a number of reasons; while an open source driver would definitely be nice to have, living in a world of patents and FCC regulations requires being flexible)

[20060227] UltraSPARC-T1 docs
Darren Reed wrote that Sun made documents relating to the UltraSPARC-T1 CPUs (niagara) available. Let's hope it's complete enough to really do a port. Oh, where do we get hardware or an emulator? And lots of spare time? :)

[20050807] Some ideas on sparc64 SMP roadmap
NetBSD is a bit *cough* behind with SMP on sparc64, but Martin Husemann has posted some thoughts on how to go on with extending the sparc64 port to use more than one CPU, starting with how to initialize them. Any takers? :)
