CONFIG_NFS_V4_2_READ_PLUS in master
by Petr Tesařík 31 Oct '23

31 Oct '23

Hi Michal, I can see that CONFIG_NFS_V4_2_READ_PLUS config option was unselected by commit ff9060bd2d1965e27f2da795a27a15d93d4cf67d. This is understandable, given mainline commit 21e31401fc4595aeefa224cd36ab8175ec867b87. However, it seems that all issues have been worked out, see mainline commit 9cf2744d249144fc0fe17667b56da78216678378. Could we re-enable CONFIG_NFS_V4_2_READ_PLUS in master now? Cheers, Petr T

cifsd-cfid-laundromat in D state
by Wolfgang Rosenauer 20 Oct '23

Hi, just tried to analyze why my idle system shows a constant load of around 7 since a while. This is 6.5.6-1-default #1 SMP PREEMPT_DYNAMIC Fri Oct 6 11:20:48 UTC 2023 (c97c2df) x86_64 x86_64 x86_64 GNU/Linux and I found it's most likely 7 cifsd-cfid-laundromat threads in D state which again pointed me at https://lore.kernel.org/lkml/457a5483c3c4ca5bb6c7ec6f4231074c.pc@manguebit.… Is the fix already in the pipeline for Tumbleweed? Thanks, Wolfgang

Updated project setup for OBS Kernel:stable:Backport and Kernel:HEAD:Backport
by Takashi Iwai 10 Oct '23

10 Oct '23

I updated the project setup of OBS Kernel:stable:Backport and Kernel:HEAD:Backport to use openSUSE:Leap:15.5:Update instead of openSUSE:Leap:15.4:Update. All packages seem built fine, so far, but if you find a problem with this change, please let us know. thanks, Takashi

Disabling /dev/fb0 on TW
by Thomas Zimmermann 10 Oct '23

tl;dr: Disable fbdev userspace interfaces on TW Hi, the upcoming Linux kernel v6.6 will contain the option to disable fbdev userspace interfaces in the kernel configuration. [1] I intent to enable this and thereby switch off /dev/fb0 et al. The tracker bug is boo#1212947. [2] * Why? The old fbdev subsystem is an endless source of bugs. For example, we recently had an out-of-bounds access in the fbdev emulation, where userspace could write beyond the end of the framebuffer memory. [3] Fbdev is under-maintained. I've been doing improvements in recent kernel releases, but only where it benefits the DRM subsystem. Disabling fbdev userspace interfaces will also help weeding out any programs that still contain hard dependencies on them. * What changes? Enabling the new kernel option disables all fbdev userspace interfaces. These are * the device files, such as /dev/fb0 * the sys files under /sys/class/graphics/fb[0-9]+ * /proc/fb * What are the effects on userspace programs? Userspace applications run on the desktop via Wayland or X. There will be no change to them. Xorg and Wayland compositors run on DRM interfaces. A few programs run on SDL, which has no dependency on fbdev either. Any fbdev support in these mid-layer components should be disabled as well. There's one known affected program: TW's text-mode installer can use the tool fbiterm to display CJK symbols during installation. This comes from a time when some low-end systems where not able to boot graphics installation. fbiterm has been unmaintained for >15 years and is ready for retirement. But there's no good drop-in replacement. I propose to simply remove fbiterm and let the graphics installer handle CJK. * What about the framebuffer console? The kernel-provided framebuffer console does not change. The kernel will still show the regular console. Userspace interfaces in /sys/class/graphics/fbcon are still available. For questions and discussion, please comment here or in boo#1212947.

Kernels fail to build in Kernel:stable:Backport
by Manfred Hollstein 09 Oct '23

09 Oct '23

Hi there, can someone please have a look at Kernel:stable:Backport to figure out why building the actual kernel packages is impossible. Looks to me like something with the recently changed binutils on Leap. E.g. https://build.opensuse.org/package/live_build_log/Kernel:stable:Backport/ke… TIA, cheers. l8er manfred
