Linux 4.15 released

Linux creator Linus Torvalds has released version 4.15 of the Linux kernel. The release was recently delayed[1] due to the disclosure of speculative execution vulnerabilities affecting many processors. “This obviously was not a pleasant release cycle, with the whole meltdown/spectre thing coming in in the middle of the cycle.

The extra two weeks were obviously mainly due to that whole timing issue,” said Torvalds[2]. Torvalds added that the release of Linux 4.15 does not mean developers are finished dealing with the vulnerabilities. There is more work to be done on patches for ARM-based processors.

Torvalds also stated that programmers need the kernel updates and a compiler with support for the “retpoline” indirect brand model to enjoy full mitigation support. “The bulk of the 4.15 work is all the regular plodding boring stuff. And I mean that in the best possible way,” said Torvalds.

Two thirds of the updates in the kernel involved drivers, which include graphics processors, input, and networking driver updates.
