Linux forking is not likely, kernel maintainer says

Filed under
Linux

Linux devotees need not worry about the Linux kernel ever forking into multiple, incompatible derivatives, Andrew Morton, lead maintainer of the 2.6 version of the kernel, said at the Open Source Business Conference here on Tuesday.

Forking of the kernel would result in a $100 million-per-year expense to maintain the forked version, thus making it undesirable for anyone to fork it, according to Morton, of Open Source Development Labs. Besides, forking would require a massive fallout amongst the kernel development team, and Morton said he has never seen any indication that that could ever happen.
"In my opinion, forking is impossible," in the Linux kernel, Morton said.

Morton acknowledged that during the SDForum open source conference, held in November in Santa Clara, Calif., he did say the kernel could be forked to accommodate sets of patches. But he clarified this statement on Tuesday.

"What I should have said in November was branching," of the kernel instead of forking, he said. Branching is a common practice in development in which a production "tree" of Linux would be branched off from the development tree, he said. Branching does not bear the negative connotations of forking, which is associated with fallout among developers resulting in the existence of multiple, incompatible versions.
Commenting on future enhancements to the Linux kernel, Morton said it could be difficult to add clustering support because there are so many different clustering technologies available, it may be hard to choose one.

"I'm pessimistic about it," he said. Morton added, though that clustering is available for Linux, but just not in the kernel.

  • DNS server attacks begin using BIND software flaw
    Attackers have started exploiting a flaw in the most widely used software for the DNS (Domain Name System), which translates domain names into IP addresses. Last week, a patch was issued for the denial-of-service flaw, which affects all versions of BIND 9, open-source software originally developed by the University of California at Berkeley in the 1980s.
  • Researchers Create First Firmware Worm That Attacks Macs
    The common wisdom when it comes to PCs and Apple computers is that the latter are much more secure. Particularly when it comes to firmware, people have assumed that Apple systems are locked down in ways that PCs aren’t. It turns out this isn’t true. Two researchers have found that several known vulnerabilities affecting the firmware of all the top PC makers can also hit the firmware of MACs. What’s more, the researchers have designed a proof-of-concept worm for the first time that would allow a firmware attack to spread automatically from MacBook to MacBook, without the need for them to be networked.

Brocade CEO: Transition To Open Source Will Be Difficult For Cisco

Communications CEO Lloyd Carney said traditional vendors like Cisco will have a tough time adapting to a more software-defined, open source space. That's because traditional vendors like Cisco's revenue streams are tied to closed architectures, Carney said. Read more
