Another source-changes catch-up (late may until second week of july 2008)
The following list gives changes to NetBSD-current
between end of may to second week of july. Note that
NetBSD is currently in a feature-freeze to prepare the
5.0 release, so there are more stability improvements
going in than new features being added:
- Work on the wrstuden-revivesa is ongoing. The old Scheduler
Activations (SA) based threading code that was removed from NetBSD
after 4.0 is adapted for NetBSD-current, so any applications that
depend on SAs can continue to run. This is important for binary
compatibility.
- More changes towards the new kernel modules (kmod) framework:
- file systems' sysctl init code is now ran in a fashion so that
the modules can either be linked statically into the kernel,
or loaded as module during runtime, without recompiling the code.
(this used to be done via some #defines previously, which either
expanded to code for the LKM, or to code for static inclusion).
- the uaudio driver can now be compiled as kmod. More work is done
to actually attach audio to newly found devices, though.
- Wasabi's journaling filesystem support was added on the
simonb-wapbl branch. There are still a number of issues to be
resolved before this gets to flight under real life conditions.
- Support for LVM as part of this year's Google Summer of Code
was added on the haad-dm branch. Currently it is possible to
create a logical volume, newfs and mount it with the Linux
lvm2tools lvcreate utility - the NetBSD driver is API-compatible
with Linux.
- After TNF has changed its copyright from 4-clause to 2-clause,
other holders of material in NetBSD's code base have made similar
changes.
- The yamt-pf42 branch was merged, which merges in a newer PF packet
filter from OpenBSD 4.2.
- Management of processor sets and thread affinity was added, see the
cpuset(3), affinity(3), pthread_setaffinity_np(3) and
pthread_getaffinity_np(3) manpages as well as the cpuctl(8) and
psrset(8) commands.
- The Red-Black-Tree code was optimized more, and moved in a place
so that the same code can be used both from userland (libc) and
kernel code.
- ifconfig(8) was changed to allow easy adding/removal of features
such as address families (inet, inet6, iso, atalk) and protocols
(802.11, 802.3ad, CARP) via the Makefile.
- SSH was extended with the HPN-SSH patch, which aims at improving
performance of SCP and the underlying SSH2 protocol by dynamically
allocating buffers. See
the HPN-SSH homepage
for more information.
