Cook: Live Patching the Kernel

Over on his blog, kernel security developer Kees Cook has a description of live patching the kernel to disable the kexec system call in older kernels. The idea is to be able to turn off kexec without rebuilding the older kernels (future kernels may be able to use the proposed /proc/sys/kernel/kexec_disabled). He examines several possible routes (ksplice, systemtap) before deciding on a more direct approach. “So, finally, I decided to just do it by hand, and wrote a friendly kernel rootkit. Instead of dealing with flipping page table permissions on the normally-unwritable kernel code memory, I borrowed from PaX’s KERNEXEC feature, and just turn off write protect checking on the CPU briefly to make the changes.

Dell Announces the Chromebook 11, Its First Chrome OS Laptop

There’s a new competitor in the Chromebook market: Dell. This morning, Dell unveiled its first Chrome OS notebook, the Chromebook 11. The sub-$300 laptop is being targeted at schools and students, and will be available next month in both the US and UK. While it’s sleek and black on the outside, on the inside its specs only seem to line up with the basic numbers we’ve been seeing lately inside of other Chromebooks. It includes an Intel Celeron 2955U processor, 16GB of internal storage, options for 2 or 4GB of RAM, and an 11.6-inch, 1366 x 768 display.

Dell says that the Chromebook 11 will last for 10 hours on a single battery charge, and that it’ll be fairly light at just 2.9 pounds. Those specs seem to give Dell a Chromebook that’s on…

Goodbye, Win XP – Hello, Linux?

Microsoft will stop security support for Windows XP this coming April, meaning that more than a few remaining users of the long-standing OS need to come up with an alternative plan. Almost a third of desktop computers still run Windows XP, according to Net Applications. Perhaps even more concerning, more than 15 percent of midsize and large enterprises will still have Windows XP running on at least 10 percent of their PCs after Microsoft support ends, Gartner estimates.

The Open Source Solution to the Bee Colony Collapse Problem

open source beehive designs

Last year, a third of honeybee colonies in the United States quite literally vanished. Commercial honey operations, previously abuzz with many thousands of bees, fell suddenly silent, leaving scientists and beekeepers alike scratching their heads. The reasons remain mostly a mystery for what is called Colony Collapse Disorder—a disturbing development of the drying up of beehives throughout the industrialised world.

Unfortunately, there’s a lot more to the problem than simply running out of honey. Bees are one of the most abundant pollinators in the natural world. They are the unsung, unpaid facilitators of human agricultural practices and have been for as long as we have sewn seeds. Their disappearance would spell disaster for our food supply, with some estimating our species lasting only four years on this planet without them. So, what can be done?
