Kernel Trap is out with a new article that talks about recent activity on the Linux Kernel Mailing List. Along with all of the other plans for the Linux 2.6.24 kernel, there is quite a bit of networking activity going on. One new feature going in is the Neptune Linux driver and extensive activity with net-2.6.24. Read all about it at Kernel Trap.
Due to a few trivial changes since the Linux 2.6.23-rc8 release, Linus has pushed out one last release candidate in the Linux 2.6.23 series. The Linux 2.6.23-rc9 kernel is going to have a lifespan of only a few days as the Linux 2.6.23 kernel release is expected in only a few days. In the Linux 2.6.23-rc9 announcement, Linus also mentioned that one of the first things to be merged for the Linux 2.6.24 kernel is the unified x86 architecture.
On the horizon for the Linux 2.6.24 kernel are several driver, USB, and PCI subsystem updates. Greg Kroah-Hartman not only made news today about developing open-source drivers free of charge to companies willing to provide the needed technical information, but he has also issued the state of the Linux Driver Core, USB, and PCI subsystems. There are a number of updates planned for these three Linux subsystems that he is the maintainer of, especially for the Universal Serial Bus (USB) in the Linux 2.6.24 kernel. Greg's status reports (as of the Linux 2.6.23-rc8 kernel) for the Linux PCI, USB, and Driver Core subsystems can be read here, here, and here.
The final release of the Linux 2.6.23 kernel is in the air. In the eighth Linux 2.6.23 release candidate there are new chips being supported by the sky2 network driver, signalfd simplification, and a number of other small fixes. More information on the Linux 2.6.23-rc8 kernel can be found at Kernel Trap.
For those using the Linux 2.6.22 kernel, the 18.104.22.168 update is now available. This update contains a single security fix for x86_64 Linux. The Linux 22.214.171.124 kernel announcement can be found on LKML.
The release of the Linux 2.6.23 kernel is quickly approaching and yesterday afternoon Linus Torvalds had released the 2.6.23-rc6 kernel. Last week was the Linux Kernel Summit (this week is the X Developer Summit) and immediately prior to this summit Linus had put out the 2.6.23-rc5 kernel; however, two nasty bugs had arose in that testing release. The missing NULL pointer and a missing list terminator in ata_piix are now corrected in the 2.6.23-rc6 kernel. This release also contains a few other updates but mostly comes down to XFS, NFS, scheduler, and m32r work. Read the announcement at LKML.org.
With the Linux Kernel Summit coming up next week in Europe, Linus Torvalds has released the Linux 2.6.23-rc5 kernel. The fifth release candidate for Linux 2.6.23 should fix most of the regressions out there. Linus classified the Linux 2.6.23-rc5 release as "fixing a number of generally pretty small issues." Find out more at Kernel Trap.
The Linux 126.96.36.199 kernel has been released. The Linux 188.8.131.52 kernel has a number of changes that includes disabling MSI on the RS690, RD580, and RX790 chipsets and fixing a number of bugs. The Linux 184.108.40.206 release announcement can be read at GMANE.
Two weeks since Linux 2.6.23-rc3, the fourth release candidate for the Linux 2.6.23 kernel is now available. This release contains an ACPI update as well as architecture updates and a variety of fixes. The 2.6.23-rc4 announcement and more details can be found at Kernel Trap.
If you're still using the Linux 2.6.20 kernel, the sixteenth iteration has been released with three security fixes. The three fixes in the Linux 220.127.116.11 kernel are for the stack-based buffer overflow in the random number generator, sending arbitrary signals to a child process that is running at higher privileges, and a security problem in the drm/i915 component. The Linux 18.104.22.168 kernel announcement can be read on Google Groups.
Succeeding the Linux 22.214.171.124 kernel is now the 126.96.36.199 kernel that presents just one security fix. This fix resets current->pdeath_signal on SUID binary execution. The 188.8.131.52 release announcement is available on the LKML.
The Linux 184.108.40.206 kernel has been released by Greg Kroah-Hartman. This release fixes a few issues along with adding the PCI ID in pata_atiixp for the ATI SB700 Southbridge. This release also contains two cpufreq on-demand fixes to increase the power savings capabilities. The Linux 220.127.116.11 release announcement can be read at LKML.
The third release candidate for the Linux 2.6.23 kernel has been pushed out. Unlike the 2.6.23-rc2 kernel where there was a wealth of changes, that's not the case this time around. The Linux 2.6.23-rc3 kernel has some scheduler updates, architecture changes for SPARC64 and PowerPC, and random driver updates. Linus Torvalds announcement can be found at LWN (among other places).
The Linux 18.104.22.168 kernel has been released with a number of bug fixes and security updates. Between the Linux 22.214.171.124 and 126.96.36.199 kernels there are over 50 changes. The release announcement can be read at LWN and all 2.6.22 users are encouraged to upgrade.
Dave Jones, the lead Fedora kernel maintainer and Linux hacker, has released the first bits of code to a new project he has been working. This new tool, acpitool, decodes ACPI tables into something that is almost like a C syntax. It's far from complete but the latest code is available from his personal website with the acpitool release announcement taking place on Dave Jones' blog.
Greg Kroah-Hartman yesterday announced the availability of the Linux 188.8.131.52 kernel. This release includes a variety of fixes with Linux 2.6.21 users being encouraged to upgrade to this latest release.
The Linux 2.6.23-rc2 kernel has been released onto kernel mirrors. This second release candidate introduces some new merges with 250 people contributing patches, but 2.6.23-rc2 is bigger than it should be and it's late as well. Linus Torvalds had stated in his announcement that "this whole '-rc2 is the new -rc1' thing is a disease." This new development kernel includes some driver changes, a MIPS update, and minor alterations all over the kernel. Additional information is available from Kernel Trap.
If you're still stuck in the Linux 2.4 kernel series, you'll be happy to know that the Linux 2.4.35 kernel has been released. This kernel comes after six months of work and integrates the changes made in the Linux 184.108.40.206 kernel combined with a number of new PCI IDs, support for high-speed USB HID, and a variety of other improvements for 2.4 kernel users. The 2.4.34.x kernel branch is now closed, but the Linux 2.4.35.x branch is open for patches. Read more at LKML.
If you're still using the Linux 2.6.16 kernel branch, the Linux 220.127.116.11 release is now available on kernel mirrors. The Linux 18.104.22.168 kernel has a security fix for a remotely triggerable NULL dereference. Among the other fixes include an IEEE-1394 forgotten dereference, array indexing fix in ntfs_init_locked_inode(), and fixing a netpoll deadlock in 8139too. The Linux 22.214.171.124 release announcement can be read on the LKML. Earlier this week the Linux 2.6.23-rc1 kernel was also released.
After a slew of git commits to the kernel tree (including user-space driver API, LGuest virtualization, KVM SMP guests, and Xen), the Linux 2.6.23-rc1 kernel has been released and the merge window is now closed until the Linux 2.6.24 kernel development is underway. Some of the other changes in the Linux 2.6.23-rc1 kernel include the usual architecture and driver updates along side the CFS scheduler and other goodies. The complete Linux 2.6.23-rc1 change-log is available from Kernel.org.
A patch for creating a stable user-space driver API has been committed to the Torvalds 2.6 kernel tree and will appear in the Linux 2.6.23 kernel. This stable user-space driver API will make it possible to write much of a driver in user-space and only a small shell of a driver in the kernel. This user-space driver API depends upon a char device and sysfs to interact with a user-space process to handle interrupts and control memory accesses. Currently this driver API will only work out for simple devices and brings no immediate hope for binary graphics drivers.
Dave Jones has handed off the reigns to David Airlie as the AGP subsystem maintainer in the Linux Kernel. While working out of Australia, David Airlie recently joined Red Hat and with him being the DRM maintainer the decision was made for him to become the AGP maintainer as well. The git commit of handing off the AGP maintenance can be read from the Kernel.org git web interface.
Yesterday we also told you about the patches being merged for the Linux 2.6.23 kernel, and now Ingo Molnar's Completely Fair Scheduler has been merged into Linux in time for the 2.6.23 kernel. The Completely Fair Scheduler has been described as modeling an "ideal, precise multi-tasking CPU on real hardware." The new scheduler replaces the O(1) scheduler that has been in the Linux kernel since 2002. Additional information is available at Kernel Trap.
With the Linux 2.6.22 kernel out the door (as well as the 126.96.36.199 kernel), we are currently in the patch merging phase for the Linux 2.6.23 kernel. Andrew Morton has posted a number of different patches to his -mm kernel tree, but not all of these patches will make it into the mainstream Linux 2.6.23 kernel. Additional information on the merging for the Linux 2.6.23 kernel is available through the Kernel.org gitweb interface and Kernel Trap.
Earlier this week the Linux 2.6.22 kernel was released, but today is already the first patch in the Linux 2.6.22 series. Greg Kroah-Hartman pushed out the Linux 188.8.131.52 kernel today after a NETFILTER exploit was quickly found. It was also a NETFILTER problem last week that caused the release of the Linux 184.108.40.206 and 220.127.116.11 kernels.
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 18.104.22.168 and 22.214.171.124 kernels. The Linux 126.96.36.199 and 188.8.131.52 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.
