  • Maintainer's / Kernel Summit 2019 planning kick-off

    The planning process for the 2019 Linux Kernel and Maintainer's Summits (Lisbon, Portugal, September 9 to 12) has begun. If you have a topic that you would like to see discussed at either event, now is the time to send in a proposal to the ksummit-discuss list; click below for the details.

  • How to securely delete files in Linux with srm

    With the Linux platform, there are a few possible tools for this process, some of which cannot be depended on for deleting such information and some which only reliably work on magnetic drives. So if your servers work with SSDs, you need to make sure to use a tool that's up for the task. One such tool is the Secure-delete Toolkit.

  • CGroup Interactions

    CGroups are under constant development, partly because they form the core of many commercial services these days. An amazing thing about this is that they remain an unfinished project. Isolating and apportioning system elements is an ongoing effort, with many pieces still to do. And because of security concerns, it never may be possible to present a virtual system as a fully independent system. There always may be compromises that have to be made.

    Recently, Andrey Ryabinin tried to fix what he felt was a problem with how CGroups dealt with low-memory situations. In the current kernel, low-memory situations would cause Linux to recuperate memory from all CGroups equally. But instead of being fair, this would penalize any CGroup that used memory efficiently and reward those CGroups that allocated more memory than they needed.

    Andrey's solution to this was to have Linux recuperate unused memory from CGroups that had it, before recuperating any from those that were in heavy use. This would seem to be even less fair than the original behavior, because only certain CGroups would be targeted and not others.

  • Intel Comet Lake Support Appears To Be In Good Shape With Linux 5.2

    Intel "Comet Lake" CPUs look like they will be well supported when running on the in-development Linux 5.2 kernel or later.

    Intel Comet Lake is the yet-to-launch successor to Coffee Lake / Whiskey Lake and, yes, yet another 14nm product and Gen 9 graphics. Comet Lake CPUs are rumored to be launched around the middle of the year and reportedly up to 10 physical cores. The most recent rumor is that Comet Lake CPUs will require a new motherboard/socket, but so far there haven't been any apparent Linux kernel commits confirming that fact.

GNOME 3.33.2 released!

Hello GNOME developers,

GNOME 3.33.2 is now available. This is the second unstable release
leading to 3.34 stable series.

I had to disable gnome-contacts, gnome-calendar and gnome-maps because of the not-very-well coordinated evolution-data-server transition.

If you want to compile GNOME 3.33.2, you can use the official
BuildStream project snapshot.

https://download.gnome.org/teams/releng/3.33.2/gnome-3.33.2.tar.xz

The list of updated modules and changes is available here:

https://download.gnome.org/core/3.33/3.33.2/NEWS

The source packages are available here:

https://download.gnome.org/core/3.33/3.33.2/sources/

WARNING!
--------
This release is a snapshot of development code. Although it is
buildable and usable, it is primarily intended for testing and hacking
purposes. GNOME uses odd minor version numbers to indicate development
status.

For more information about 3.34, the full schedule, the official module
lists and the proposed module lists, please see our 3.33 wiki page:

https://www.gnome.org/start/unstable


Cheers,

Abderrahim Kitouni,
GNOME Release Team

Security Leftovers

  • Serious Security: Don't let your SQL server attack you with ransomware [Ed: Article focuses on things like Windows and RDP. SQL Server is proprietary software that runs on a platform with NSA back doors. So if you choose it, then you choose to have no security at all, only an illusion of it. Why does the article paint Windows issues as pertaining to MySQL?]
    Tales from the honeypot: this time a MySQL-based attack. Old tricks still work, because we're still making old mistakes - here's what to do. [...] As regular readers will know, one of the popular vehicles for malware crooks at the moment is Windows RDP, short for Remote Desktop Protocol.
  • How Screwed is Intel without Hyper-Threading?
    As it stands Microsoft is pushing out OS-level updates to address the four MDS vulnerabilities and you’ll get those with this month's Windows 10 1903 update. However, this doesn’t mitigate the problem entirely, for that we need motherboard BIOS updates and reportedly Intel has released the new microcode to motherboard partners. However as of writing no new BIOS revisions have been released to the public. We believe we can test a worst case scenario by disabling Hyper-Threading and for older platforms that won’t get updated this might end up being the only solution.
  • SandboxEscape drops three more Windows 10 zero-day exploits

    SandboxEscaper also indicated that she was in the market to sell flaws to "people who hate the US", a move made in apparent response to FBI subpoenas against her Google account.

  • Huawei can’t officially use microSD cards in its phones going forward

    The SD Association is also by no means the first to cut ties: Google, ARM, Intel, Qualcomm, and Broadcom are also among the companies that have stopped working with Huawei due to the ban. The Wi-Fi Alliance (which sets Wi-Fi standards across the industry) has also “temporarily restricted” Huawei’s membership due to the US ban, and Huawei has also voluntarily left JEDEC (a semiconductor standards group best known for defining RAM specifications) over the issues with the US as well, according to a report from Nikkei Asian Review. All this could severely hamper Huawei’s ability to produce hardware at all, much less compete in the US technology market.

  • Huawei barred from SD Association: What’s that mean for its phones and microSD cards?

    As such, companies that aren’t on the SD Association’s list of members can’t officially produce and sell devices with SD card support that use the SD standards. According to SumahoInfo, the member page showed Huawei a few weeks ago, but no longer lists the firm this week.
