Linux 4.0 Kernel Released

An anonymous reader writes "The Linux 4.0 kernel has been released. Linux 4.0 brings many features including live patching, Radeon DisplayPort Audio, RadeonSI fan control improvements, new OverlayFS functionality, Intel Quark SoC support, and a heck of a lot more. Linus's release announcement reads in part: "So I decided to release 4.0 as per the normal schedule, because there really weren't any known issues, and while I'll be traveling during the end of the upcoming week due to a college visit, I'm hoping that won't affect the merge window very much. We'll see. Linux 4.0 was a pretty small release both in linux-next and in final size, although obviously 'small' is all relative. It's still over 10k non-merge commits. But we've definitely had bigger releases (and judging by linux-next v4.1 is going to be one of the bigger ones)."

Re:Is it as secure as OpenBSD's kernel?

Here's the list, though a few are mis-filed (the arbitrary code execution from this year is actually in Flash, no idea why it appears here), but most of the privilege elevation ones from this year and most of the arbitrary code execution vulnerabilities are real (though several seem to be in Logitech HID drivers).

variation in user land and "GNU/Linux"

[DrYak]

In practice Bash is part of most Linux installations.

Even in the realm of "GNU/Linux" not everybody uses bash (some use zsh, for exemple).

And that's only the portion of users running an actual "GNU" userland.

Then you have the embed world using Busybox (with uClib, etc.) and co for the userland (which has its own simplified shell).
And then you have Android (which runs a completely different user land by Google, like Bionic for a C library, a different message passing bus, and most of the things usually handled by deamon running in userland, handled by java-like code on a java-like VM).

And the other way arround: you have other Unice (OS X, various *BSD) which obviously do not run Linux kernel, but do run bash.
OS X, for example, was affected by bash.
