The current 2.6 kernel is 2.6.3
, which was released
on February 17. Only a handful of
patches have gone in since the last release candidate. Overall, 2.6.3
includes a great deal of internal cleanup work, the removal of the USB
scanner driver (in favor of the user-space libusb solution), the new
generic DMA pool mechanism, "context mount" support for SELinux,
a big ALSA update, a fix for the new mremap()
and quite a few architecture
updates. See the long-format changelog
During the last week, we also saw 2.6.3-rc3
(changelog) and 2.6.3-rc4 (changelog).
The current kernel tree from Andrew Morton is 2.6.3-mm1. Recent additions to the -mm tree
include some more scheduler improvements, a new CPU hotplug implementation,
journaled quotas for the ext3 filesystem, and numerous fixes.
2.6.3-mm1 also contains the new device mapper crypto target
code. This target allows the creation of encrypted filesystems by way of
the device mapper (LVM) subsystem. If things work out, this approach is
likely to replace the (buggy) cryptoloop driver; if you have an interest in
encrypted filesystems, testing out this patch might be a good idea.
The current 2.4 kernel is 2.4.25, released by Marcelo on February 18. Among
other things, this release includes the mremap() vulnerability
fix. Marcelo has had a busy week, having previously released 2.4.25-rc2, -rc3, and -rc4.
