Linus Torvalds has today released the Linux 2.6.22 kernel. The Linux 2.6.22 kernel features the SLUB allocator replacing the slab allocator, a brand new wireless stack, several new device drivers, and a new Firewire stack. Linus' announcement with additional details is available at Kernel Trap.
Hitting the web on Friday afternoon was the Linux 188.8.131.52 and 184.108.40.206 kernels. The Linux 220.127.116.11 and 18.104.22.168 kernels fix a security problem with netfilter messages and Greg KH strongly urges all Linux 2.6.20 and 2.6.21 users that rely upon netfilter to upgrade to this latest version.
After Alan Cox recently posted a status report for libata PATA on the Linux Kernel Mailing List, Kernel Trap has a summary of the Linux IDE status. There is still plenty of work left to be tackled with libata such as adding proper PATA hot-plug support and a PowerPC port. Support for the ATIIXP Chipset is currently rock-solid with Linux and libata while many PATA Chipsets are still deemed experimental.
What will hopefully be the last release candidate in the Linux 2.6.22 series is now out the door. The biggest chance in the Linux 2.6.22-rc7 kernel deals with a defconfig update but there are a number of other fixes as well. The Linux 2.6.22-rc7 announcement can be found at LKML.
The Linux 2.6.22 kernel is nearing completion and the sixth release candidate has been released. This release should fix a number of regressions and other issues introduced in the 2.6.22-rc5 kernel. Linus' announcement for the Linux 2.6.22-rc6 release with additional details can be found on the Linux kernel mailing list.
With Memorial Day coming up on Monday, Linus Torvalds has released the Linux 2.6.22-rc3 kernel in time for some extra testing over the holiday weekend here in the US. This third release candidate offers embedded hardware architecture updates (ARM, SH, and Blackfin), ATA updates, USB suspend fixes, network driver updates and network fixes, and quite a few other changes. Kernel Trap has the 2.6.22-rc3 announcement with some additional commentary.
Hitting the web yesterday was the Linux 2.6.22-rc2 kernel. This release candidate contains random fixes along with architecture changes and libata and driver updates. Linus Torvalds' announcement for this kernel can be read at LWN.
The Linux 2.6.22-rc1 kernel has hit the web with almost seven thousand files changed. However, when it comes to new features in this first Linux 2.6.22 testing release are architecture updates, drivers, file-systems, networking, and a variety of other improvements. Some of the new specific improvements include a new Firewire stack, new wireless networking infrastructure, new digital video drivers, and a brand new CPU architecture. Kernel Trap has provided some additional information on this announcement.
If you've been experimenting with the idea of writing device drivers for Linux, Free Software Magazine has written an extensive article on this topic. The article starts with the differences between kernel-space and user-space components and then ends with using LEDs connected to a parallel port as the device. This how-to guide can be read here.
Interested in knowing what patches have been merged so far into the -mm kernel and will likely end up in the Linux 2.6.22 mainstream kernel? Kernel Trap has a short article and Andrew Morton's message with what is being merged in time for the Linux 2.6.22 kernel (well, so far). If you missed it, the Linux 2.6.21 kernel is now available.
It was not even a week ago that the Linux 2.6.21 kernel was released, but now the 22.214.171.124 kernel has entered the world. The first minor revision in the Linux 2.6.21 branch fixes an RT0 header IPv6 change and a fix for the netlink fib. The 126.96.36.199 change-log is available here and the source is available from Kernel.org.
After the release of the Linux 188.8.131.52 and 2.4.35-pre4 kernels earlier in the week and being two weeks since the availability of Linux 2.6.21-rc7, the Linux 2.6.21 kernel has now been officially released. The major change in Linux 2.6.21 are all of the changes in the timers and dynticks to support a tick-less kernel. Additional information on the Linux 2.6.21 kernel is available from Kernel Trap.
If you're still using the Linux 2.4 kernel, being released today is the Linux 184.108.40.206 kernel along with the 2.4.35-pre4 kernel. The day started off with the release of the Linux 220.127.116.11 and the 2.4.35-pre3 kernel, but a fib_semantics patch had broken that build resulting in a same-day re-release. The new 2.4.34 kernel contains a large amount of bug-fixes along with a small security fix. The latest 2.4.35 pre-release kernel features driver updates and other changes. As always, the latest vanilla kernel sources are available from Kernel.org. The Linux 2.6.21 kernel should be released in just a matter of days.
Kernel Trap has new coverage of the completely fair Linux scheduler. This new scheduler is currently available via a patch-set known as the "Modular Scheduler Core and Completely Fair Scheduler". This scheduling project is a complete rewrite and offers some very interesting changes. Check it out here.
If Linux 18.104.22.168 isn't your thing and you enjoy venturing into unchartered territory, Linus Torvalds has released the Linux 2.6.21-rc7 kernel. In this release candidate are mostly driver fixes along with some networking fixes and NFS changes. If some regressions can be cleared, Linus hopes to push out the Linux 2.6.21-final kernel next weekend. The Linux 2.6.21-rc7 release announcement comes today from LWN.
