Kernel Development Continues Despite In-fighting

Filed under
Linux

Speaking at Linux Australia's annual Linux conferernce, Linux.conf.au, in Canberra last week, Colorado-based Linux kernel developer Jonathan Corbet said predicting kernel development is hard but is "possible".

The current kernel version, 2.6.11, to be succeeded by 2.6.12, will include support for trusted computing and SELinux (security enhanced Linux) for multi-level security.

Corbet didn't announce when version 2.6.12 will be out other than to say "sometime soon".

"It depends on what the developers do and even Linus [Torvalds] doesn't really try," Corbet said. "Even so, some predictions are possible by looking at work that is in progress now and user needs which are unmet."

Proposed patches go to Andrew Morton and eventually to Linus Torvalds who merges them into the mainline tree.

Corbet conceded that not all goes "that smoothly" but the process is working "better than ever".

Other features Corbet earmarked for 2.6.12 include Red Hat's contribution of address space randomization for defence against buffer overflow attacks and remote script kiddies, and multipath I/O support to rival "fancy" storage systems that offer redundancy and load balancing.

Users can also look forward to native virtualization support with Xen.

"Xen creates a new architecture and you can run Windows," he said. "It has nice features like being able to take a virtual host and move it to another machine while it's running."

The Linux filesystem family will also be added to with Reiser4, "a fast, transactional filesystem that has problems but will eventually go into the mainline tree."

Other enhancements will be in the clustering and embedded systems arena, and software suspend will allow a state to be suspended to disk or memory.

All these new features bode well for Linux server applications, however, improving the desktop won't be overlooked.

"inotify is a better file modification notifier which will keep file managers current," Corbet said. "And kernel events notification is an effort to make hardware 'just work'."

Kernel events notification will tell user space applications when something happens such as a CD being inserted or a camera is attached.

Although Corbet said latency issues will remain for a while, which matters for desktops and the overall "feel" of the system, it will improve over time.

"The radical approach to improving latency is to include Ingo Molnar's real-time pre-emption patch but this is a huge intrusive change so expect a debate," he said. "This could be the motivation for a 2.7 branch."

Tor: Statement

Seven weeks ago, I published a blog post saying that Jacob Appelbaum had left the Tor Project, and I invited people to contact me as the Tor Project began an investigation into allegations regarding his behavior. Since then, a number of people have come forward with first-person accounts and other information. The Tor Project hired a professional investigator, and she interviewed many individuals to determine the facts concerning the allegations. The investigator worked closely with me and our attorneys, helping us to understand the overall factual picture as it emerged. Read more

  • New Taskotron tasks
    For a while now, Fedora Quality Assurance (QA) is busy with building Taskotron core features and didn’t have resources for additions to tasks that Taskotron runs. That changed a few weeks back when we started running task-dockerautotest, task-abicheck and task-rpmgrill tasks in our development environment. Since then, we are happy with the results of those tasks. We deployed them to the production instance last week. Please note that the results of those tasks are informative only. Let’s introduce the tasks briefly.
