Kernel prepatch 4.0-rc1

By corbet Linus has closed the merge window for this release and released 4.0-rc1 — meaning, of course, that the current
plan is to call the release “4.0”. “But nobody should
notice. Because moving to 4.0 does *not* mean that we somehow changed what
people see. It’s all just more of the same, just with smaller numbers so
that I can do releases without having to take off my socks again.

The codename has also changed to “Hurr durr I’ma sheep.”

Green: Another update on the Truecrypt audit

By jake On his blog, Matthew Green gives an update on the plans to audit the TrueCrypt disk encryption tool. Green led an effort in 2013 to raise money for an audit of the TrueCrypt source code, which sort of ran aground when TrueCrypt abruptly shut down in May 2014. “It took us a while to recover from this and come up with a plan B that works within our budget and makes sense. We’re now implementing this. A few weeks ago we signed a contract with the newly formed NCC Group’s Cryptography Services practice (which grew out of iSEC, Matasano and Intrepidus Group). The project will evaluate the original Truecrypt 7.1a which serves as a baseline for the newer forks, and it will begin shortly. However to minimize price — and make your donations stretch farther — we allowed the start date to be a bit flexible, which is why we don’t have results yet.

EFF: Lenovo is breaking HTTPS security on its recent laptops

By corbet Here is a
statement from the Electronic Frontier Foundation
on the revelation
that Lenovo has been shipping insecure man-in-the-middle malware on its
laptops. “Lenovo has not just injected ads in a wildly inappropriate
manner, but engineered a massive security catastrophe for its users. The
use of a single certificate for all of the MITM attacks means that all
HTTPS security for at least Internet Explorer, Chrome, and Safari for
Windows, on all of these Lenovo laptops, is now broken.
” For
additional amusement, see Lenovo’s
statement
on the issue.

There are a lot of Lenovo users in LWN’s audience. Presumably most of them
have long since done away with the original software, but those who might
have kept it around would be well advised to look into the issue; this site can evidently indicate
whether a machine is vulnerable or not.

FreeBSD random number generator broken for last 4 months

By jake As several LWN readers have pointed out, John-Mark Gurney posted a message to the freebsd-current mailing list on February 17 noting that the random number generator (RNG) in the FreeBSD “current” kernel has been broken for the last four months. “If you are running a current kernel r273872 or later, please upgrade
your kernel to r278907 or later immediately and regenerate keys. I discovered an issue where the new framework code was not calling
randomdev_init_reader, which means that read_random(9) was not returning
good random data. read_random(9) is used by arc4random(9) which is
the primary method that arc4random(3) is seeded from.

This means most/all keys generated may be predictable and must be
regenerated. This includes, but not limited to, ssh keys and keys
generated by openssl. This is purely a kernel issue, and a simple
kernel upgrade w/ the patch is sufficient to fix the issue.”
