The discussion on Linux Saloon highlighted various tech topics, particularly regarding Google's Android ecosystem changes and sideloading. Participants shared their experiences with custom Android ROMs and alternatives. The session also covered significant developments, including a leaked AI source code, critical security flaws in Telegram, and an increase in Steam's Linux usage.

Last year we went to Japan to finally visit friends after two decades of planning to. Because they live in Fukuoka, we only ended up visiting Hiroshima, Kyoto and Osaka afterwards. We loved it there and as soon as cheap flights became available, booked another one for Tokio, to be legally allowed to cross off Japan as visited.

Now if I were to book the trip today, I probably wouldn't. It's quite a gamble given the geopolitical situation and Asia running out of oil. But making it back, it's been as good as the first one. Visiting only Tokio with a short trip to Kawaguchiko in the Sakura blooming season worked out great.

At the start of the year I promised myself to shoot my Fuji more. And I don't mean the volcano, I mean the my X-T20. I haven't kept the promise at all, always relying on the iphone. Luckily for the trip I didn't chicken out carrying the extra weight and I think it paid off. I did only take my 35mm, as the desire to carry gear has really faded away with the years. As we walked over 120km in the few days my back didn't feel very young even with the little gear I did have.

While the difference in quality isn't quite visible on Pixelfed or my photo website (I don't post to Instagram anymore), working through the set on a 4K display has been a pleasure. Bigger sensor is a bigger sensor.

Check out more photos on photo.jimmac.eu -- use arrow keys of swipe to navigate the set.

I also managed to get both of my weeklybeats tracks done on the flight so that's a bonus too!

Japan is probably quite difficult to live in, but as a tourist you get so much to feast your eyes on. It's like another planet. I hope to find more time to draw some of the awesome little cars and signs and white tiles and electric cables everywhere.

New Features and Enhancements

Plasma 6.6.1, 6.6.2 & Plasma 6.6.3: Version 6.6.3 finished the month with the third update. Application launcher Kicker receives several fixes for the sidebar, icon display, and expanded root list width calculations. The Task Manager now keeps thumbnails properly aligned in horizontal group tooltips. Spectacle resolves a crash on quick region selection and fixes a pixel-off error in the magnifier tool. The system tray sees improved popup placement on Wayland. PowerDevil restores the battery badge for 100 percent charge and syncs the manual inhibition switch with external changes. Plasma 6.6.2 has KWin resolve crashes in DRM output handling, improves mouse tracking with caret-based zoom, and fixes input region gaps in window decorations. The Kicker applet sees refinements in visual search, scrollbar behavior, and hover logic. Spectacle fixes a crash when exporting via KDE Connect, and System Settings now correctly navigates to subcategories from search results. In version 6.6.1, KWin sees the most changes with fixes for corner rounding applying to both decorations and window surfaces, zoom now works correctly on rotated outputs, and software brightness dimming on external screens on screens were enhanced. The tile editor no longer triggers on key repeat, and interactive move-resize no longer unconditionally raises windows. Clipboard and drag-and-drop teardown under XWayland is improved, and*Wine/Proton color management gains better compatibility. The Kicker application launcher for the Plasma Desktop receives multiple fixes for the icon display, layout margins, and search field behavior. The Task Manager corrects tooltip sizing. The digital clock now properly localizes digits, and the media controller fixes premature label truncation. Plasma Network Manager improves icon accuracy for Wi-Fi disabled states and now responds to external configuration changes. Discover improves Flatpak app resolution and exposes proper star count ratings. Powerdevil adds a power level check before executing critical actions that prevent premature shutdowns.

GNOME Control Center 49.5: The Display and Power panels now handle a missing UPower service instead of failing. An infinite loop when switching battery charge modes on systems with multiple batteries was fixed. Sound and Bluetooth device switching regressions are resolved through an updated libgnome-volume-control.

libxml2 2.15.2: A significant version jump that removes the built-in HTTP client and LZMA compression support, and the parser option XML_PARSE_UNZIP is now required to read compressed data. HTML serialization and character encoding handling are brought more in line with the HTML5 specification, and additional accessors for xmlParserCtxt were added for developers. Several previously patched CVEs are now resolved upstream, including fixes for attribute normalization and standalone checks. Python bindings are no longer built as they are scheduled for removal in 2.16, and Schematron support has similarly been dropped.

Xfce 4.20.2: This update covers the screensaver, session manager, and display settings. xfce4-screensaver fixes a wrong conditional in the lock plug, improves theme preview rendering, and switches from pidof to pgrep for more reliable process detection. The overlay window handling is reworked to use a single permanent window, improving device reliability. xfce4-session fixes an idle function and prevents multiple logout dialogs from being created. It also adds gnome-keyring as a Secret portal provider and improves keyboard layout detection on Wayland. xfce4-settings improves display management by checking EDID to detect output list changes, adds a missing condition for new Wayland outputs, and falls back to output name when EDID data is duplicated.

KDE Frameworks 6.24.0: This updates see KIO gain nanosecond-precision timestamps across file operations, improved paste dialogs with proper titles, and refined trash handling. KCodecs overhauls encoding with safer memory management (using unique_ptr) and Kirigami introduces a new StyleHints API to unify theme behavior. Baloo fixes database access mode issues and KTextEditor adds search history clearing and safer clipboard handling.

7-Zip 26.00: The file manager now uses the file name as a secondary sorting key for more intuitive file list ordering, and the benchmark tool supports systems with more than 64 CPU threads. A bug preventing correct extraction of TAR archives containing sparse files is fixed.

KDE Gear 25.12.3: Kdenlive addresses numerous stability and usability issues, including crashes in the curve editor, audio scrubbing with “Pause on Seek” disabled, and provides better handling of multi-stream clips and improved effect management. Itinerary and Kitinerary expand travel support with new extractors for ferry tickets. NeoChat refines room list navigation, fixes emoticon editor layout issues, prevents timeline scrolling during reactions, and resolves a crash. KMail restores proper rendering of plain-text emails and Tokodon fixes alt-text editing and account switching after login failures.

ImageMagick 7.1.2.16 - 7.1.2.18: The image editor update for version 7.1.2.18 improves the reliability of animated image handling by fixing frame delay parsing and resolves a visual artifact where the -dissolve composite operation introduced random noise. Version 7.1.2.17 focused on addressing multiple vulnerabilities and security advisories are resolved along with out-of-band data handling improvements. Version 7.1.2.16 hardens security and adds overflow checks to several image write paths including JXL, PS3, sixel, SGI, and BMP/DIB. It fixes a heap over-read in BilateralBlurImage with even-dimension kernels, a NULL pointer dereference in HEIC NCLX color profile allocation, and a double-free in SVG gradientTransform parsing.

Ruby 4.0.2: This update fixes a YJIT bug. A segfault with argument forwarding combined with splat and positional arguments is resolved, along with a GC crash in String#% and a crash on signal raise. A 20 percent performance regression in Rails related to global allocatable slots and empty pages is addressed. Several Prism parser issues were corrected including misparsing of standalone in pattern matching and the and? predicate being confused with the and keyword.

FreeRDP 3.24.1: This update sees the API comprehensively marked with [[nodiscard]] to surface unchecked function return values. Smartcard support is improved including ECC key handling in PKCS#11 enumeration, proxy support is extended to RFX and NSC graphics modes, and SDL3 multi-monitor scaling is introduced. Numerous memory leaks across connection setup, settings copying, and smartcard paths were resolved.

libavif 1.4.0: This update adds support for Sample Transform schemes from the AVIF 1.2 specification, which enables 16-bit AVIF file handling and grid-based derived image items. Data behind a document for the software handles picture files was made with avifenc, which can now read PNG or JPEG files through stdin via --stdin-format and supports converting JPEG files with Apple-style gain maps. PNG decoding now respects cICP chunks for color information as per the PNG Third Edition specification. Encoding defaults have been refined; AOM_TUNE_IQ is now used for still color samples with libaom v3.13.0+, while AOM_TUNE_PSNR is used for alpha to avoid ringing artifacts from SSIM tuning. Support for libaom versions 2.0.0 and earlier is removed.

Key Package Updates

Linux kernel 6.19.5 - 6.19.9:: The 6.19.9 update improved audio with a speaker pop fix for Star Labs StarFighter hardware and the Btrfs filesystem resolves a space info lock issue during periodic reclaim. NFS3 now correctly returns EISDIR when a create operation encounters a directory alias. The 6.19.8 kernel was dominated by a major batch of AppArmor fixes and multiple CVE-tracked fixes that were backported. The 6.19.7 release receives multiple corrections for CFS/EEVDF scheduler including fixes for zero_vruntime tracking, lag clamping, and slice protection timing. The AMD XDNA accelerator driver resolves several issues including a crash when destroying suspended hardware contexts. The 6.19.6 kernel had fixes led by extensive perf tooling corrections including reference count leaks, srcline printing with inlines, and Zen 5 vendor event definitions for AMD. Btrfs replaces a BUG() call with proper error handling for unexpected delayed ref types, adds fallback to buffered IO for data profiles with duplication, and improves user interrupt handling in btrfs_trim_fs(). The 6.19.5 releases sees Btrfs correct a block_group_tree dirty list corruption and a chunk allocation abort caused by non-consecutive gaps. GFS2 resolves quota handling and an inline data write path. The SMB client fixes a potential use-after-free and double free in smb2_open_file(). A netfilter nf_tables fix adds an abort skip removal flag for set types to address tracked security-relevant issues.

GStreamer 1.28.1: This update includes a new whisper-based speech-to-text transcription element and the speechmatics element now supports detecting audio events like applause, laughter, and music. Reverse playback and gap handling are improved across multiple components. The V4L2 subsystem gains support for AV1 stateful decoding, and CUDA/GL interop copy paths in cudaupload and cudadownload are fixed. WebRTC components gain the ability to specify custom headers for signalling servers and negotiate H.264 profile and level for encoded input. Various memory leaks, build issues, and race conditions were resolved.

curl 8.19.0: This release addresses four security vulnerabilities and provides new features like initial support for MQTTS and fractional values for --limit-rate and --max-filesize. Support for OpenSSL-QUIC was dropped. A potential NULL dereference in Curl_h1_req_parse_read() was fixed along with a potential out-of-bounds read in OpenSSL debug logging. The build now enables NTLM authentication for compatibility with certain Exchange Server endpoints.

systemd 259.3 & 259.5: The 259.5 update had a notable fix and corrected systemd-update-helper from incorrectly skipping systemctl disable during package removal. A new clean-state command is introduced and triggered automatically at the end of any transaction installing unit files. The systemd-container subpackage now requires libarchive instead of tar for archive handling. Additional systemd-update-helper fixes address do_install_units() incorrectly returning an error when no units need preset, and the clean-state command itself is corrected to remove the full state directory rather than just a subdirectory. The 259.3 was a major version upgrade. The libcap dependency was removed entirely, with its system call wrappers reimplemented directly in systemd.

GnuPG 2.5.18: This update adds support for deleting composite secret keys in gpg-agent and fixes armor parsing when no CRC is found. A recent regression in pkdecrypt with TPM RSA keys is resolved, and scdaemon adds support for D-Trust Card 6.1/6.4. The dirmngr key server search now prints all UID records for a key, which fixes a regression dating back to 2015.

Mesa 26.0.2: The release fixes visual corruption on RDNA 4 in DX11/DXVK titles like Mafia III, a GPU hang with PS epilogs and secondary command buffers, and missing L2 cache invalidation with streamout on GFX12. A Counter-Strike 2 visual glitch regression on Intel A770 is resolved. The Panfrost Bifrost compiler fixes a failure from incorrect vectorization and spill placement issues. An OpenGL VRAM memory leak when setting uniform variables is corrected. X11 shared memory attachment checks are added across drisw, EGL, GLX, and Vulkan WSI paths to prevent allocation failures.

GTK3 3.24.52: This update fixes a Firefox crash at gdk_wayland_drag_context_manage_dnd() when a toplevel Wayland surface is missing, and resolves wild strobing in multi-window mode. A refresh rate calculation overflow on 32-bit targets is corrected, and recolored icon images are no longer constantly reloaded. Accessibility events for unfocused GtkTreeView widgets are fixed, and XKB initialization failures on Wayland are now handled more gracefully.

libtpms 0.10.2: This update fixes a memory leak by freeing the KDF context and resolves incorrect IV retrieval when using OpenSSL 3.0 or later. A build fix for compatibility with newer glibc is also included. For Tumbleweed users running TPM-based virtualization with QEMU or swtpm, this is a security-relevant update.

xfsprogs 6.18.0: This update spans three releases. The mkfs.xfs tool gains several improvements including the ability to configure desired maximum atomic write sizes, AG size alignment based on atomic write capabilities, autodetection of log stripe unit for external log devices, and new default features enabled out of the box with a 2025 LTS config file. Zoned filesystem support is refined with fixes for zone capacity checks on sequential zones and improved default maximum open zones. The proto subsystem adds the ability to populate a filesystem directly from a directory. xfs_scrub removes its EXPERIMENTAL warnings and fixes a null pointer crash in scrub_render_ino_descr. Cross-architecture log CRC mismatches between i386 and other architectures are corrected, and libxfs gains support for reproducible filesystems using deterministic time and seed values. Deprecated sysctl knobs and mount options are removed. The Python dependency is also dropped from the main package since the xfs_protofile script is not essential.

Conclusion

March 2026 was a month defined by refinement and security hardening across the openSUSE Tumbleweed stack. The three Plasma 6.6 point releases demonstrated KDE’s steady cadence of desktop polish, while the kernel’s progression from 6.19.5 to 6.19.9 kept hardware support and filesystem reliability moving forward. Security was a clear theme throughout the month, with FreeRDP, curl, libsoup2, and the kernel itself all receiving significant CVE attention alongside a broad sweep of image processing fixes across GraphicsMagick, ImageMagick, and exiv2. Under the hood, the jump to libxml2 2.15.2 marked a meaningful step forward in web standards alignment, and GStreamer 1.28.1 pushed multimedia capabilities forward with speech-to-text transcription and AV1 decoding support.

The series for openSUSE Leap 15 is coming to an end after nearly eight years of providing a consistent community distribution that’s upgradable to SUSE’s enterprise product. Leap 15.6 will reach End of Life (EOL) at the close of this month closing out an end of an era as it will no longer receive maintenance or security updates going forward.

The Leap 15 journey began it journey on May 25, 2018, when 15.0 was released as a fresh community build on top of SUSE Linux Enterprise 15. It brought a huge variety of new software along with a easy migration to SLE, transactional updates, server roles, scalable cloud images, and more.

What followed was an impressively long run of incremental releases from Leap 15.1 to 15.6 as each stable release aligned with its twin, which is source and binary compatible, and delivered maintenance and security updates to users over several years.

The series far exceeded promises and ultimately spanned nearly eight years of active support. With Leap 15.6 going EOL, users who wish to continue receiving maintenance and security updates should upgrade to Leap 16. Leap 16 is expected to go to 16.6 in Fall 2031 and will have 24 months of support for a point release.

Running an unsupported release means your system will no longer receive patches for vulnerabilities, which poses a real security risk over time. The upgrade path to Leap 16 is the recommended way to stay protected and supported.

You can download openSUSE Leap 16 and use the migration tool to upgrade.

Leap 15.6 itself received nearly 24 months of support, which extended the traditional support period of 18 months by about six months. With Leap 16, users can expect a full 24 months of community support per point release, which is a commitment that reflects the significant effort from maintainers to keep users protected.

Thank you to all the contributors, packagers, and users who made the Leap 15 series such a long-lasting and reliable platform. Here’s to the next chapter with Leap 16!

Almost 15 years ago, Balabit had a campaign, stating that syslog-ng could process 650k messages a second. Now I am happy to present 7 million EPS (events per second). Timing the announcement to April 1 is not a coincidence :-)

While the 650k EPS measurement was true, it was misleading. This value was measured right after syslog-ng 3.2 introduced multi-threading, in lab environment, under optimal circumstances, using synthetic log messages. However, there was no fine print explaining this, just the statement that syslog-ng could process 650k EPS. It was fixed after a while, but it took years to recover from the effects of this marketing campaign, and engineers ten years later still had a nervous breakdown when someone mentioned “650k”. Why? Because from that moment, everyone expected syslog-ng to collect logs at that message rate in a production environment with complex configurations. Which was of course not the case.

Fast-forward to today, I’m happy to share that:

syslog-ng can collect logs at 7 million EPS

• Is this measurement value valid? Yes.

• Does it apply to real world? No.

• Does it sound good? Definitely :-)

The tool: sngbench

I love playing with various non-x86 systems. I have various ARM, POWER, MIPS systems at home, and sometimes I access other architectures, like RISC-V remotely. And, of course, not just different architectures, but different operating systems: various Linux distributions, MacOS, FreeBSD, sometimes also other BSD variants. I’m a server guy, and for the past 15+ years: a syslog-ng guy. Sometimes I had access to an exotic system on the other side of the world only for less than an hour, but I almost always tested syslog-ng.

For many years I had a bunch of shell scripts and configs to benchmark syslog-ng performance. Not for real world production loads, but rather for comparing architectures and operating systems. I needed a script which could do measurements with minimal dependencies and do it quickly, in one go. This is how sngbench was born, based on my previous ugly scripts. It has quite a few advantages and shortcomings:

• Minimal dependencies: bash and syslog-ng

• No complex setup: everything runs on the same host

• network bandwidth is not a limiting factor

• loggen and syslog-ng processes are competing for resources

• Two bundled configurations: a performance tuned and the default syslog-ng.conf from openSUSE with minimal modifications to add a TCP source

• By default, very short (20 seconds) measurements, so disk I/O is not a limiting factor

• Many different test scenarios: from a single TCP connection to 4 * 128

Of course this describes just the “factory defaults”. You can easily change the test scenarios and configurations too.

How I reached 7 million EPS, and why it is not relevant

I was testing syslog-ng code which was not yet even merged to the development branch. First, I tested these patches with various settings. Along the way I remembered that Splunk guidelines mention so-rcvbuf tuning also for TCP connections. Previously I only used that for optimizing UDP performance. Now I have done it for TCP. Wonders happened :-)

But, of course, the main question is: can you achieve this performance in production? TL;DR: No.

My tests are run from localhost. Network bandwidth is not an issue. Tests are run in short bursts. This is peak performance; when it comes to writing logs to files or forwarding to a cluster of Splunk or Elasticsearch endpoints around the clock, that would be slower. Also, in my fastest test case, logs came from four different loggen instances, over 32 TCP connections each, at a constant rate. In the real world, logs come in bursts and connections are opened and closed regularly.

Test environment and tests

I used my AI mini workstation with Fedora Linux 44 Beta. First, I took a base line with stock syslog-ng 4.11.0 included in the distribution. Then I used my syslog-ng git snapshot packages for Fedora from https://copr.fedorainfracloud.org/coprs/czanik/syslog-ng-githead/. Initially it also had jemalloc support compiled in. Later I disabled it and purely focused on the yet to be merged parallelize() optimizations from GitHub. I experimented with enabling and disabling parallelize(), adding various batch_size() values, and finally also so-recbuf().

I gave a proprietary tool a fair chance - and was not disappointed

The views expressed in this post are my own and do not represent the position of my employer. This post is not a commercial endorsement of QASE or any of its products.

I very seldom write about proprietary solutions and software. Not because I have any problem with them, but simply because I usually prefer open source solutions, and during my daily work and hobby projects I use almost exclusively open source software.

My AI mini workstation from HP has seen some non-AI workloads this weekend. I installed Capture One for photo editing and a couple of software synthesizers. And realized along the way that while built-in speakers are nice, high-end audio is a lot better! :-)

For months, I have been listening to music on devices that are designed for speech: a pair of Jabra headphones and the speakers of my various laptops. There were many reasons for this, including peer pressure, and some hearing loss at a way too loud concert. I was also lazy to use my high-end devices and tried to persuade myself that audio equipment designed for meetings is good enough for music too. Well…

This weekend, I installed various software synthesizers on my new computer. Not that I learned music or could play any instruments, but I still enjoy experimenting with music (well, with noise, actually :-) ). As I connected the machine to the big screen in the living room, I also connected it to my HiFi system. Suddenly, I realized how much better it sounds than my laptop or anything I’ve listened to in the past few months.

While making noise with a couple of software synths and listening to music from my TIDAL subscription, I also recharged my Focal headphones. My Focal Bathys is not as good as my HiFi, but also has a wonderful sound regardless.

So I guess that after a few months long detour, I am back to using high-end audio gear whenever it is technically possible. I love the extra detail I can hear on my Heed Enigma speakers or on my Focal headphones. Of course, nothing can replace listening to live music at concerts, but high-end gear is much better at approximating the vibe of various live events than anything below it.

Dear Tumbleweed users and hackers,

After a high-speed run, we hit a wall this week: only two snapshots (0324 and 0326) reached the mirrors. The culprit was a combination of bad timing and a necessary course correction regarding our bootloader defaults.

It is now clear that the previous move to grub2-bls was a mistake. We are correcting that decision by switching modern systems to systemd-boot. This transition caused a “weekend blackout” because openQA changes for the new default were deployed last Friday, but the actual distribution changes didn’t land until Sunday. We spent Monday and Tuesday ironing out the resulting kinks, which cost us the weekend snapshots.

While the change to systemd-boot is a significant highlight for fresh installations, it was just one of many updates that landed this week:

• systemd-boot: Now the default for fresh installations (upgraders remain on their existing bootloader).
• AppArmor 4.1.7
• KDE Plasma 6.6.3
• ffmpeg 8.1
• FreeRDP 3.24.1
• gettext 1.0
• Linux kernel 6.19.9
• qemu 10.2.2
• SQLite 3.51.3

The package maintainers and release engineers are busy preparing the next few changes for the upcoming days. These include:

• GNOME 50: matplotlib’s test suite needs to accept deprecations in glib 2.88.0
• Autoconf 2.73
• Linux kernel 6.19.10
• Qt 6.11.0
• Mozilla Firefox 149.0
• GCC 16 as the default distro compiler
• LLVM 22
• glibc 2.43: metabug: https://bugzilla.opensuse.org/show_bug.cgi?id=1257250
