OpenSSH 8.2 Released With FIDO/U2F Support


OpenSSH 8.2 is out this Valentine’s Day as the leading SSH suite. Besides working to disable the SSH-RSA public key signature algorithm due to SHA1 collision attacks, OpenSSH 8.2 also comes with new features.

The shiny new feature of OpenSSH 8.2 is support for FIDO/U2F hardware authenticators. FIDO/U2F two-factor authentication hardware can now work with OpenSSH 8.2+, including ssh-keygen can be used to generate a FIDO token backed key. Communication to the hardware token with OpenSSH is managed by a middleware library specified via the SSH/SSHD configuration, including the option for its own built-in middleware for supporting USB tokens.

Besides FIDO/U2F support in OpenSSH 8.2, other changes in this release include further defenestrating SSH-RSA for certificate signatures, a new “Include” keyword for including additional sshd configuration files, various portability improvements, and a number of bug fixes.

Ubuntu 20.04 + Linux 5.5: Fresh Benchmarks Of AMD EPYC Rome vs. Intel Xeon Cascade Lake

Here are some fresh numbers looking at the current performance of various AMD EPYC 7002 “Rome” processors up against Intel Xeon Cascade Lake processors when using an Ubuntu 20.04 LTS development snapshot and also upgrading to Linux 5.5 as the latest stable kernel. Beyond raw performance, power efficiency and performance-per-dollar for these different server CPUs are being compared as well for these sub-$5000 processors.

Ahead of the Ubuntu 20.04 long-term support release this spring and being curious how the latest AMD EPYC and Intel Xeon CPUs are competing with a bleeding-edge software stack also including Linux 5.5, this fresh benchmark comparison was performed. The single-socket tests carried out for this article included the:

– AMD EPYC 7302

– AMD EPYC 7402

– AMD EPYC 7502

– AMD EPYC 7642

– Intel Xeon Silver 4216

– Intel Xeon Gold 5218

– Intel Xeon Platinum 8253

The comparison was limited to the EPYC / Xeon CPUs we had available that are of a retail price of $5000 USD or less. It’s also the first time we are looking at some of those Xeon Cascade Lake parts in this comparison. All systems were tested with the same 8 x 16GB DDR4-3200 Crucial ECC Registered memory and 3.8TB Micron 9300 NVMe solid-state drive. On the AMD EPYC side was the ASRockRack EPYCD8 motherboard and on the Intel side was the Supermicro X11SPL-F motherboard. Both systems were running their latest BIOS and that paired with the latest software stack of Ubuntu 20.04 + Linux 5.5 with all default mitigations on each platform.

The overall AC system power consumption was being monitored in real-time using a WattsUp Pro power meter. The performance-per-dollar on the benchmarks were also calculated using the current retail pricing for these various EPYC and Xeon CPUs as of testing time.

All of these benchmarks were carried out in a fully-automated and reproducible manner using the Phoronix Test Suite for our first Xeon vs. EPYC comparison of 2020 on the latest open-source Linux software.

Firefox 73 + Firefox 74 Beta Benchmarks On Ubuntu Linux

Given this week’s release of Firefox 73 stable that also puts Firefox 74 into beta state, here are fresh Firefox browser benchmarks of Firefox 72/73/74 on Ubuntu Linux with and without WebRender as well as how it compares to the current state of Google Chrome.

These benchmarks today are looking at the performance of Firefox 73 and looking ahead at how the performance is shaping up for Firefox 74 with the initial beta release. Secondary runs were also performed when force-enabling WebRender.

All these Mozilla Firefox and Google Chrome benchmarks were carried out in a fully-automated and reproducible manner using the Phoronix Test Suite.

Wayland 1.18 Released With Meson Support, Other Minor Changes


Wayland 1.18 is out today as the first update to the core Wayland code in nearly one year.

Eleven months have already passed since the release of Wayland 1.17 while on Tuesday was succeeded by Wayland 1.18.

Wayland 1.18 brings Meson build system support similar to the Weston compositor and other open-source projects. Wayland 1.18 also now uses MEMFD_CREATE in the cursor code where possible, support for letting compositors setting a zero output refresh rate for use-cases like virtual/remote outputs, API support for allowing applications and toolkits to share the same Wayland connection, documentation improvements, and other minor work.

Wayland 1.18 isn’t all that exciting with the Wayland Protocols having been spun out into their own repository for a while, Weston being the “proving grounds” for all the compositor-level innovations, and then all the real-world Wayland compositors taking shape in their respective repositories.

The brief Wayland 1.18 release announcement can be found on Wayland-devel. The Wayland 1.18 release comes just a few weeks after the recent Weston 8.0 compositor feature release.

Red Hat’s Stratis 2.0.1 Released For This Linux Storage Management Solution


Red Hat’s Stratis storage project for offering enterprise storage capabilities on Linux to compete with the likes of ZFS and Btrfs while being built atop LVM and XFS saw the first update to its daemon of 2020.

Stratis 2.0.1 is coming after the 2.0 release in November that brought new D-Bus API usage and other improvements. Stratis 2.0.1 brings improved logging, various D-Bus changes, refactored device discovery, a refactored idempotency implementation, and various other fixes and low-level improvements. There isn’t a whole lot in 2.0.1 with it being a patch release but another step forward for Stratis Storage.

Looking ahead, for Stratis 3.0 will bring more features with previous plans calling for compression, encryption, deduplication, and other features when it should really reach feature parity with ZFS.

More details on v2.0.1 and the other workings of this Red Hat storage offering can be found via stratis-storage.github.io.
