Mesa, Disk Encryption, Xfce Packages Update in Tumbleweed

This week has provided many openSUSE Tumbleweed snapshots focusing on hardware, graphics, desktop environment and more.

From Mesa to the disk encryption package cryptsetup and Xfce software to GraphicsMagick, the snapshots are rolling with new software updates.

The GraphicsMagick 1.3.40 package arrived in the most recent snapshot, 20230215. The ImageMagick fork that focuses on programming Application Programming Interfaces and command-line options fixed a 20-year old bug in the WordPerfect Graphics header reading. The package also provided some new features and has PCX and DCX file support for writing an uncompressed format. An update of gnome-shell 43.3 plugged a leak, fixed a crash and cleaned up some code. A major version update of text shaping engine harfbuzz arrived in the snapshot; moving from the 6.0 version to the 7.0 version, the package brought experimental support to cubic curves in the glyf data table, and it has a new command line utility, hb-info, for querying various font information. A few other updates were made in the snapshot.

Snapshot 20230214 delivered the disk encryption package with the cryptsetup 2.6.1 update. The version fixed a possible iteration overflow in the OpenSSL2 PBKDF2 cryptography backend. The package also fixes a possible hash offset setting overflow, and it does not initiate a re-encryption command when the header and data devices are the same. The changelog states that if data device reduction is not requested, it leads to data corruption since the Linux Unified Key Setup metadata would be written over the data device. An update of NetworkManager 1.42.0 adds support for source load balancing for ethernet bonds and adds support of IPv4 for the Equal-Cost Multi-Path routes. The ECMP routes will be merged. A Common Vulnerability and Exposure patch was dropped in the guestfs-tools 1.50.0 package. CVE-2022-2211 is a flaw that leads to a denial of service either by mistake or by a malicious actor, but it is considered to have a low impact for the package that is used for accessing and modifying virtual machine disk images. The updated package also has a new ‘virt-drivers’ tool; the tool can be pointed at a disk image that lacks metadata and, in some circumstances, can determine useful information about it such as what bootloader it contains and what device emulation it needs to boot. The update of kernel-firmware 20230210 adds missing tuning files for HP Laptops using Cirrus Amplifiers and adds firmware for Cirrus CS35L41 on an ASUS laptops. Some other packages to update in the snapshot were gnome-control-center 43.4.1, libzypp 17.31.8, yast2 4.5.24, vim 9.0.1307 and more.

The 20230212 snapshot focused mostly on updates for Xfce users. The xfce4-power-manager 4.18.1 version updated translations, fixed the management of source identification and implemented a fall back on the lock command with the screensaver should the D-Bus call fail. Some memory leaks were fixed with the xfce4-session 4.18.1 update. Several blurry icons were made more sharp with the update of xfce4-settings 4.18.2, and a duplicated configuration line was removed. The update of patterns-xfce 20230212 replaced gnome-calculator with galculator since it better integrates with the Xfce look and feel. A few changes were also made to the yast2-iscsi-client 4.5.7 version.

An update of nodejs19 19.6.0 in the 20230211 snapshot upgraded the npm dependency to version 9.4.0, and it removed an s390 patch after the fix upstream was accepted. An update of gnome-software 43.4 had some AppStream changes, and gnome-contacts 43.1 fixed several bugs when updating or editing a contact. The GTK+ bluetooth manager, blueman, updated to version 2.3.5 and enabled a plugin that was providing connection errors to devices as well as fixing a right click with a wrong pointer. The update of the dbus-1 1.14.6 version fixed a crash with some glibc versions when non-auditable SELinux events are logged. The updated version also fixed some documentation. GNOME’s personal management application evolution was updated to version 3.46.4, and converts the mail signature into markdown language, which was co-developed by Aaron Swartz.

The 20230210 snapshot from last Friday brought Mesa and Mesa-drivers 22.3.5, which had no new features, but it did fix null descriptors and had a fix for RB+ for sRGB formats. Xfce’s text editor mousepad had some code refactoring and code cleanup in the 0.6.0 version. The 15.2 postgresql15 release took care of CVE-2022-41862, which a server could report an error message containing uninitialized bytes and could make a message accessible to an attacker. A few other packages were updated in the snapshot.

Mi escritorio Plasma de febrero 2023 #viernesdeescritorio

Otro mes más que sigo con la serie de la iniciativa #viernesdeescritorio con una nueva captura, con la que llegaré a más de un año y medio compartiendo «Mi escritorio» de forma mensual, una mirada a la intimidad de mi entorno de trabajo. De esta forma, bienvenidos a mi escritorio Plasma de febrero 2023, el segundo del año, que está dedicado al recientemente lanzado Plasma 5.27, último de la serie, y con el que utilizaré su tema básico claro.

Mi escritorio Plasma de febrero 2023 #viernesdeescritorio

Esta va a ser la trigésimasegunda vez que muestro mi escritorio Plasma 5 en público, lo cual es número nada desdeñable de entradas que sigue creciendo de forma constante. Hice un recopilatorio con los 12 escritorios del 2022 y tengo pendiente seguir con otros, para finalizar con una entrada que los recopile todos… pero eso será en un futuro.

Respecto al mes pasado, y como he dicho en la introducción, está basado en el tema Brisa del VDG de la Comunidad KDE: tema global, ventanas, colores, iconos, etc.

Respecto a plasmoides, he despejado el escritorio de ellos ya que me ha gustado tanto el fondo de pantalla que me apetecía verlo sin distracciones, dejando solamente el plasmoide Modern Clock, que encaja a la perfección. El resto de cosas que necesito (calendario, conexiones, volumen, etc,) lo tengo en la barra de tareas a un solo click.

Y cambio, tras unos meses mostrando mi Slimbook Kymera AMD de sobremesa, a realizar la captura sobre mi portátil Slimbook Pro de 13 pulgadas, el cual tiene instalado un KDE Neon con Plasma 5.27, siendo mi sistema gráfico Wayland que ya ha se ha establecido definitivamente.

El resultado de mi escritorio de febrero de 2023 es un entorno de trabajo claro y, como siempre, funcional que podéis ver en la imagen inferior (pinchad sobre ella para verlo un poco más grande).

Easy CPU Benchmarking on Linux

I have spent a disproportionate of my time looking at CPU Benchmarks because numbers are fun. There are a lot of ways to benchmark and test your system and frankly most of them are too complex for me to really care. I like numbers but when they get into real nuanced details my eyes glaze […]

Episodio 13 de KDE Express: Car Edition + I love Free Software Day

Tras unos meses de silencio me congratula presentaros que tenemos a nuestra disposición el episodio 13 de KDE Express, titulado Car Edition + I love Free Software Day, un monólogo a cargo de David Marzal donde da las gracias a un buen número de personas, proyectos y comunidades que hacen que el Software Libre sea lo que es: la única alternativa sostenible si queremos tener libertad y tecnología.

Episodio 13 de KDE Express: Car Edition + I love Free Software Day

Comenté ya casi hace un año que había nacido KDE Express, un audio con noticias y la actualidad de la Comunidad KDE y del Software Libre con un formato breve (menos de 30 minutos) que complementa los que ya genera la Comunidad de KDE España de forma casi mensual con sus ya veteranos Vídeo-Podcast que podéis encontrar en Archive.org, Youtube, Ivoox, Spotify y Apple Podcast.

Episodio 13 de KDE Express: Car Edition + I love Free Software Day

De esta forma se llega al número 13, el primero de su segunda temporada y que cuenta con el incombustible e hiperactivo David Marzal, para dar su particular y preciosa visión del I love Free Software Day.

En sus palabras:

Ante la falta de tiempo pero con mucha ilusión con el proyecto de KDE, encontramos nuevas formas de conseguir haceros llegar información de nuestra comunidad. Inicialmente pensado para grabar andando al trabajo, pero finalmente de vuelta de la escuela de la peque, os dejamos un nuevo modelo de episodio «In itinere», con la inestimable ayuda de Jorge Lama, tanto como consejero «audífono», como nuevo editor y garante de un audio decente para vuestros oídos.

Y, como siempre, os dejo aquí el listado de los episodios. ¡Disfrutad!

A mi me sigue gustando mucho, es rápido, directo al grano y muy dinámico, con lo cual es ideal para aquellos que les guste tener su pincelada de Kdeera en su podcaster. Evidentemente, no se profundiza en temas aunque si se da una visión muy personal de los mismos.

Por cierto, también podéis encontrarlos en Telegram: https://t.me/KDEexpress

Releasing version 0.7

Although we have been actively working on YaST and D-Installer, we have been silent since the beginning of December. We are sorry for that! Today we are resuming our blogging activity announcing the availability of D-Installer 0.7. Let's look at what it is new and what you can expect from the upcoming releases.

You can download the latest ISO from the openSUSE Build Service if you want to give it a try.

Iterating towards a better user interface​

In every release, apart from adding features and fixing bugs, we put some effort into improving the user interface. If you check the latest version, one of the most relevant changes is the introduction of the much-awaited hamburger menu. Although quite some work remains to be done, several actions found a new home in this menu (gh#yast/d-installer#379).

Hamburger menu

Another significant change, especially from the developer's point of view, is the rework of the UI to use plain CSS as much as possible for building the layout instead of relying on lots of wrapper components (gh#yast/d-installer#391).

But that's not all! We also did a bunch of minor fixes worth mentioning, like correcting some miss-alignments, adding an icon for the software section, fixing the fonts loading, and so on (gh#yast/d-installer#401).

Software proposal validation​

Software management is one of the areas that took more attention for this release. Relying on the validation mechanism (a.k.a. pre-installation checks) we introduced in version 0.6, we added support to report problems like unreachable repositories or missing patterns and packages (gh#yast/d-installer#381 and gh#yast/d-installer#414)

Software proposal validation

Additionally, D-Installer gracefully handles the case where you do not have a working network connection (e.g., on a wireless setup). Once the connection is ready, it refreshes the repositories information without user intervention.

Browsing and downloading the YaST logs​

Making it easy for our users to report bugs is becoming critical for the D-Installer development. Although it was already possible to use the save_y2logs script to gather the logs, we have decided to add Download logs action to our new and shiny hamburger menu (gh#yast/d-installer#379).

Alternatively, you can inspect them in the browser just by using the Show logs option. We plan to improve this feature by adding search capabilites, filters, etc. (gh#yast/d-installer#407).

Using a dedicated D-Bus server​

This change is not visible to our users, but it is interesting if you want to know about the internals. D-Installer components use D-Bus for communication. Until now, we were using the system bus and everything was fine. However, as we advanced into proper support for Iguana, we noticed that we needed our own bus, in addition to the system one (gh#yast/d-installer#384).

But that's not all...​

As usual, there are many other changes that we did not mention. However, we would like to give you some pointers to them just in case you are interested:

What's next​

Apart from the changes we have presented, we are working in many other areas. So let's check what you can expect from the upcoming releases.

  • iSCSI support. We are almost there: the D-Bus API is finished and we are working in the web user interface. We expect it to be ready for the next release.
  • Automated installation. We are in the early stages (choosing a file format, thinking about backward compatibility, etc.). However, due to the architecture of D-Installer, we are rather optimistic and the first bits could be included in the next release too.
  • S/390 architecture support. It is under heavy development. It might take a bit of time, but we are collaborating with other teams within SUSE to make it possible ASAP.
  • Enable integration testing. This one is becoming a hot topic for us. We are in close contact with our QA experts to enable proper integration testing.
  • Rework the overview page. Last but not least, we are working on a rework of the overview page. We want to offer a more coherent user experience. Of course, it should be ready for the time of the next release.

Conclusions​

The development of D-Installer continues at good pace. If you are interested, please, do not hesitate to give it a try and report any bug you might find. You can contact us through the GitHub project's page or, as usual, in our #yast channel at Libera.chat or the YaST Development mailing list.

Syslog-ng 101, part 7: Networking

This is the seventh part of my syslog-ng tutorial. Last time, we learned about syslog-ng destinations and the log path. Today, we learn about syslog-ng network logging. At the end of the session, we will send test messages to a syslog-ng network source.

You can watch the video on YouTube:

Or you can read the rest the tutorial as a blog at: https://www.syslog-ng.com/community/b/blog/posts/syslog-ng-101-part-7-networking
