Git, curl, systemd Roll with Tumbleweed

Filed under
SUSE

openSUSE Tumbleweed gave rolling release users a snapshot every day this past week.

The latest snapshot to be released was 20211124. This snapshot brought systemd 249.7, which focused on package tests and updated dependencies for the testsuite. The text editor vim had a minor update to version 8.2.3640, but it was filled with many fixes; some of the fixes included taking care of a memory leak, crashes and performance issues related to GTK. The removal of a redundant script header was made in the update of dracut and optimal compression parameters were made for zstd in the Linux-boot process package. Other packages to update in the snapshot were autoyast2 4.4.22, embedded Linux library ell 0.46, GNOME’s document viewer evince 41.3 and gtk-vnc 1.3.0.

MicroOS Expands Security With Keylime

Filed under
SUSE

Recently MicroOS gained some new options in relation with security. The distribution has now integrated Keylime, an open source project for doing remote attestation with TPMs.

If you follow the news about Windows 11, you are aware of what is a TPM. The Trusted Platform Module (TPM) is a cryptoprocessor, described by the Trusted Computing Group (TCG) in a specification that has been standardized in a ISO/IEC document. You can find the TPM already soldered in the mainboard of your computer, but they can also be found as a service in the firmware, or inside your CPU.

This co-processor can be used for many tasks related with security. For example, we can use it to generate symmetric and asymmetric keys, encrypt some memory blocks (not too big, as they are a bit slow), or to as storage for keys that can be used only for us (or applications that have permissions).

  • NetBSD Project Report: Add support for chdir(2) support in posix_spawn(3)

    The primary goal of the project was to extend posix_spawn(3) to include chdir(2) for the newly created child process. Two functions were supposed to be implemented, namely posix_spawn_file_actions_addchdir() and posix_spawn_file_actions_addfchdir(), to support both chdir(2) and fchdir(2) respectively. posix_spawn() is a POSIX standard method responsible for creating and executing new child processes.

  • STFC: Using Kubernetes to better understand climate change | SUSE Communities

    “The team at STFC were looking for a vendor-backed solution to help manage its Kubernetes estate. Working with SUSE Rancher, the Kubernetes architecture was easy to deploy, manage and scale.” Sheng Liang, President of Engineering and Innovation, SUSE.

  • Thank you, SUSE QE

    Some here might not know it, but some teams from the 'SUSE Quality Engineering Linux Systems Group' use the Redmine installation here at https://progress.opensuse.org/ to track the results of the test automation for openSUSE products. Especially openQA feature requests are tracked and coordinated here.

    As the plain Redmine installation does not provide all wanted features, we included the "Redmine Agile plugin" from RedmineUP since a while now. Luckily the free version of the plugin already provided nearly 90% of the requested additional features. So everybody was happy and we could run this service without problems. But today, we got some money to buy the PRO version of the plugin - which we happily did Smile

SUSE/OpenSUSE: MicroOS, Rancher, and OpenSUSE Survey

Filed under
SUSE
  • MicroOS Remote Attestation with TPM and Keylime

    During 2021 we have been starting to focus more in security for MicroOS. By default MicroOS is a fairly secure distribution: during the development all the changes are publicly reviewed, fixes (including CVEs) are integrated first (or at the same time) in Tumbleweed, we have read-only root system and a tool to recover old snapshots, and periodically the security team audit some of the new components. Also, the move from AppArmor to SELinux should help to standardize the security management.

    But we really want to rise the bar when it is possible. For example, we are starting to think on how to enable IMA/EVM properly in the distribution, or what alternatives we have for full disk encryption supported by a TPM. There are some evaluation on dm-verity inside the new Transactional Image Update installer.

    Another area where we make progress in MicroOS is how to measure the health of our systems, detect remotely when an unauthorized change has been made (remote attestation), and actuate over it globally and as fast as possible.

openSUSE Leap vs Tumbleweed: What’s the Difference?

Filed under
SUSE

openSUSE is a very popular Linux distros, especially in the enterprise world. SUSE has been around in one form or another since 1996. During most of that time, they have only had one version.

Then, in 2015, they changed things up and decided to offer two versions: Leap and Tumbleweed.

If you are new to openSUSE, it is easy to get confused between Tumbleweed and Leap. A reader recently asked us to explain the similarities and difference between the two, that’s just what we’ll do today.

VirtualBox, Plasma, systemd Updates in Tumbleweed

Filed under
SUSE

Rolling release users had a variety of package updates this week to include updates of rpm, Plasma, rsyslog, webkit2gtk3, systemd, AppStream and more, which were updated throughout the week’s four openSUSE Tumbleweed snapshots.

The latest snapshot to be released, 20211027, updated eight packages. Mozilla Thunderbird 91.2.1 increased the memory required per threads for AArch64 to avoid an out of memory state and the email client also had Link Time Optimization enabled for Tumbleweed. The php7 7.4.25 update was a security release focusing on bug fixes like one that affected high memory usage during encoding detection and another fix addressed Common Vulnerabilities and Exposure–2021-21703. The 9.22 version of the real-time web framework perl-Mojolicious added a referer method and fixed the response status log message to use the trace log level instead of debug. A second release this week of mpg123 updated the package to version 1.29.2, which had a single fix for a non-live-decoder safeguard. AppStream, which is a cross-distribution package for standardizing software component metadata, updated to version 0.14.6; the new version updated documentation and added support for source locales. The package also added support for image and video screenshot handling and the changed states that it added Fedora to the continuous integration environment.

Snapshot 20211025 had an update of rpm 4.17.0. The update had many improvements, new translations and python generators and debuginfo extraction have been split into a separate upstream project. The rsyslog had two updates in Tumbleweed this week and this snapshot brought in version 8.2110.0, which fixes a couple of bugs affecting configurations. The 5.14.14 Linux Kernel had a whole bunch of fixes for Advanced Linux Sound Architecture and Btrfs. There were also several 4.2.20 library updates for libyui , which implemented the C++17 standard for package plugins. Another update in the snapshot was the update of the Free Remote Desktop package freerdp 2.4.1; the package update addressed two CVEs and one of those was an improper client input validation for gateway connections that would allow to overwrite memory.

Kernel and Graphics: Linux Stuff and GPUs

  • Facebook/Meta Tackling Transparent Page Placement For Tiered-Memory Linux Systems - Phoronix

    Back during the Linux 5.15 cycle Intel contributed an improvement for tiered memory systems where less used memory pages could be demoted to slower tiers of memory storage. But once demoted that kernel infrastructure didn't have a means of promoting those demoted pages back to the faster memory tiers should they become hot again, though now Facebook/Meta engineers have been working on such functionality.  Prior to the Linux 5.15 kernel, during the memory reclaim process when the system RAM was under memory pressure was to simply toss out cold pages. However, with Linux 5.15 came the ability to shift those cold pages to any slower memory tiers. In particular, modern and forthcoming servers with Optane DC persistent memory or CXL-enabled memory, etc. Therefore the pages are still accessible if needed but not occupying precious system DRAM if they aren't being used and to avoid just flushing them out or swapping to disk. 

  • Linux 5.17 To Boast Latency Optimization For AF_UNIX Sockets - Phoronix

    Net-next has been queuing a number of enticing performance optimizations ahead of the Linux 5.17 merge window kicking off around the start of the new year. Covered already was a big TCP optimization and a big improvement for csum_partial() that is used in the network code for checksum computation. The latest optimization is improving the AF_UNIX code path for those using AF_UNIX sockets for local inter-process communication.  A new patch series was queued up on Friday in net-next for improving the AF_UNIX code. That patch series by Kuniyuki Iwashima of Amazon Japan is ultimately about replacing AF_UNIX sockets' single big lock with per-hash locks. The series replaces the AF_UNIX big lock and also as part of the series has a speed-up to the autobind behavior. 

  • Nvidia Pascal GPU, DX12 and VKD3D: Slideshow time! - Boiling Steam

    So Horizon Zero Dawn had a sale recently on Fanatical, and I thought… OK I’ll grab it! It’s time. I first installed it on my workstation that only has a GTX1060 3GB GPU – not a workhorse but a decent card nonetheless for low-to-medium end gaming. I knew very well that Horizon Zero Dawn is a DX12 game and that Pascal architecture (Nvidia 10xx basically) and earlier versions do not play very well with DX12 games running through vkd3d-proton, the DX12 to Vulkan translation layer. Still, I could imagine getting somewhere around 30 FPS on low-to-medium settings, and use FSR if necessary to get to better framerates. Nothing prepared me for the performance I was about to experience.

Linux 5.16-rc3

So rc3 is usually a bit larger than rc2 just because people had some
time to start finding things.

So too this time, although it's not like this is a particularly big
rc3. Possibly partly due to the past week having been Thanksgiving
week here in the US. But the size is well within the normal range, so
if that's a factor, it's not been a big one.

The diff for rc3 is mostly drivers, although part of that is just
because of the removal of a left-over MIPS Netlogic driver which makes
the stats look a bit wonky, and is over a third of the whole diff just
in itself.

If you ignore that part, the statistics look a bit more normal, but
drivers still dominate (network drivers, sound and gpu are the big
ones, but there is noise all over). Other than that there's once again
a fair amount of selftest (mostly networking), along with core
networking, some arch updates - the bulk of it from a single arm64
uaccess patch, although that's mostly because it's all pretty small -
and random other changes.

Full shortlog below.

Please test,
