Using Rowhammer bitflips to root Android phones is now a thing

LXer - Mon, 2016-10-24 05:34
Previously, some experts believed Rowhammer attacks that altered specific pieces of security-sensitive data weren't reliable enough to pose a viable threat because exploits depended on chance hardware faults or advanced memory-management features that could be easily adapted to repel the attacks. Now, an international team of academic researchers is challenging those assumptions by demonstrating a Rowhammer exploit that alters crucial bits of data in a way that completely roots name brand Android devices from LG, Motorola, Samsung, OnePlus, and possibly other manufacturers. An app containing the researchers' rooting exploit requires no user permissions and doesn't rely on any vulnerability in Android to work.

Something for encrypting data via a pipe

Reddit - Mon, 2016-10-24 04:13

There is a utility called mcrypt which is intended for encrypting data in a pipe (for example, tar cvf - foo/ | xz -v9e | mcrypt ), but I read it was deprecated. What is a good, supported replacement. I just need a simple utility to encrypt multi-gigabyte .txz (.tar.xz) files before I throw them into remote storage. There is always PGP or gpg, but I really don't need all that overhead, when I'm using a static key.

Linux 4.9-rc2

TuxMachines - Mon, 2016-10-24 04:00
  • Linux 4.9-rc2

    I'm back on my usual Sunday afternoon release schedule, and 4.9-rc2 is out.

    My favorite new feature that I called out in the rc1 announcement (the
    virtually mapped stacks) is possibly implicated in some crashes that
    Dave Jones has been trying to figure out, so if you want to be helpful
    and try to see if you can give more data, please make sure to enable

    .. and on the other hand, if you want to just not have to worry about
    _that_ particular issue, disable the virtually mapped stacks it for
    now, but please do help test.

    Because 4.9 is obviously shaping up to be a big release (I haven't
    done the actual stats yet, but I think it's the biggest in number of
    commits we've ever had), and I think Greg is also planning on making
    it an LTS release. The two may be related, with people pushing to get
    their stuff ready. Regardless, the more people who help test, and the
    earlier in the rc series those people start testing, the better off
    we'll be. Hint hint.

    Ok, enough about that. rc2 itself isn't huge, but that's a fairly
    common pattern: either people just take a breather after the merge
    window, or it simply takes a while for the fallout of new code to be
    found, so rc2 is usually a fairly small rc.

    But we have stuff pretty much all over the map: drivers dominate (gpu
    drivers stand out, but there's ipmi, clocksource, mmc, pinctrl, HID,
    scsi, nvme .. you name it). Add some architecture updates (x86 and
    arm64) and a few filesystems (ext4, nfs, ceph, f2fs), and some VM
    cleanups and one big fix, and you've covered most of it.

    The appended shortlog gives the details, and for even more detail you
    can always go to the git tree itself.


  • Linus Torvalds Announces the Second Release Candidate of Linux Kernel 4.9 LTS

    It's still Sunday in the US, which means that it's time for you to take yet another RC (Release Candidate) milestone of the upcoming Linux 4.9 kernel release for a test drive.

    That's right, Linus Torvalds just announced the second Release Candidate for Linux kernel 4.9, which lands eight days after the first one and appears to be fairly normal development snapshot that includes lots of updated drivers, mostly for GPU, but also HID, SCSI, MMC, PINCTRL, IMPI, and clocksource, various x86 and ARM64 architecture updates, improvemnts to the EXT4, F2FS, Ceph, and NFS filesystems, and some VM cleanups.

  • Linux 4.9-rc2 Kernel Released

    Linux 4.9-rc2 is now available as the latest test release of this forthcoming kernel update.

    Over the past week there's been a fair number of merges of bug/regression fixes for this stage of Linux 4.9 development, one week since the closure of the merge window.

    We've already written a lot about Linux 4.9, including our detailed Linux 4.9 feature overview for those interested in the fun changes of this next kernel release.

Which porn site in youtube-dl allows downloading entire channels ?

Reddit - Mon, 2016-10-24 01:05

xvideo, xhamters, pornhub ?

I am trying to bulk download tube porn since I wont have internet during my holidays.

I use youtube-dl to bulk download ( cache ) music and porn.

With porn the process is too slow. I need to fill 8 TB and its not happening fast enough :(

I need to individually download each video .. ughh.

torrenting is a lot slower, and the quality is not on par with stream sites.

Also I like my porn short with a lot of variety. Most normal torrent porn is too long for my taste.

Looking to purchase new laptop for Linux, any suggestions?

Reddit - Mon, 2016-10-24 00:56

I am looking to switch over to Linux for the first time so I can have more security/privacy when going online to access my email, Amazon and browsing YouTube/Reddit. I am currently using Windows 7 desktop which I will keep for gaming purposes, but would like to get a laptop running Linux so I can do all my non-gaming activities in a more secure environment. Any suggestions for a reliable laptop that supports Linux? I have not decided which distro I will be using yet, however any advice that could help me make a informed decision would be greatly appreciated. I will not be using linux for gaming.

The basics of open source quality assurance

LXer - Sun, 2016-10-23 23:51
Open source depends on a sustainable community to develop code rapidly, debug code effectively, and build out new features. Because community involvement is voluntary, people's skills, levels of involvement, and time commitments can vary. Given the variable nature of these factors, along with the fact that open source often relies on a philosophy of "release early, release often," quality assurance can be become challenging.read more
