[20080225] 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! :)
