Linux 4.2 released
Linus has been busy toiling away on the next version of the Linux kernel, and now version 4.2 has finally been released.
Linus made the official announcement on the kernel mailing list:
So judging by how little happened this week, it wouldn't have been a mistake to release 4.2 last week after all, but hey, there's certainly a few fixes here, and it's not like delaying 4.2 for a week should have caused any problems either.
So here it is, and the merge window for 4.3 is now open. I already have a few pending early pull requests, but as usual I'll start processing them tomorrow and give the release some time to actually sit.
The shortlog from rc8 is tiny, and appended. The patch is pretty tiny too.
Richard Chrigwin reports on Linux 4.2 for The Register:
Now that it's general availability, the kernel does bring some goodies worth having. The Crypto Forum Research Group's ChaCha20 stream cipher and the Poly1305 authenticator (a reference implementation is described in RFC 7539) are supported, and there's a new RSA implementation.
To improve random number seeding, Linux 4.2 uses CPU execution jitter to help seed its random number generator, a feature called “jitter entropy RNG” on the basis that sushi should be called “cold dead fish”.
The default crypto random number generator API is now DRBG.
LinuxPlanet notes that there's also support for security module stacking.
The release of Linux 4.2 spawned a thread on the Linux subreddit:
Santsi: "X-box controller is fixed. Best release ever."
Oversizedhoodie: "Yay! Jack detection support for I2S audio!"
Kamize: ”I love this!! Ubuntu Studio will take a while to catch up to using 4.2 though.”
Jimrandom: ”In a brief moment of senility, I read that as "Linux 2.4 is out." I thought I was back in the dark ages.”
Roscocoltrane: ”I have a gaming AMD (HD7970) desktop on fedora 22. Does it make sense to install the new kernel or will I still be limited by xorg and different stuff anyway?”
