I've got a patchset that makes coredump install a pidfd for the coredumping task into the file descriptor of the process that is exec'd as a usermode helper during a pipe-based coredump. For example, systemd-coredump could set:

|/usr/lib/systemd/systemd-coredump %P %u %g %s %t %c %h %F

and %F will make the kernel install a pidfd as file descriptor number 3 for the coredumping task.

Barebones, untested, no commit messages yet:

Useful?

So small update on #linux on #arm chromebooks: the kernel installation process involves writing binary images as a partition instead of putting the #kernel files on a /boot partition.
To get the currently running kernel config I used "modprobe configs" and you get a compressed config under /proc/config.gz,
I copied and extracted the file to compile with mainline/gentoo kernel sources.
I added the drivers via "make menuconfig" and compiled the kernel.
Reminder that usually this is a monolithic kernel without initrd, so the drivers needed to boot the system are not compiled as a module.
Thanks to hexdump0815 for the documentation:

I finally got round to (mostly) scripting my "FOSS activity in ..." summaries. So I've now posted my last 6 months' activity on https://www.decadent.org.uk/ben/blog/
#debian #linux #kernel

This is how my terminals look like when I compile a kernel. I love the wonderful colours that I generate

#bash #sh #zsh #ksh #csh #kernel #Linux #POSIX #FOSS #100daysofCode #640DaysOfCode #1024DaysOfCode #programming #lolcat

Yes, "Several" vulnerabilities found

Update your boxen, Linux folks!

Out of curiosity:

Does anyone know how to check when #Linux distributions with #LinuxKernel live patching services (like RHEL, SLE, or Ubuntu) rolled out live patches for certain CVEs?

Asking, as I noticed that CISA recently added two known exploited #kernel vulnerabilities to its catalog[1] which upstream fixed more than three months ago[2, 3]. And that made me wonder when live patches for those went out.

Linux 6.15 exFAT Can Delete Files Much Faster: 4+ Minutes To 1.6 Second Optimization

Weird bug with #KDE: I updated my system (#Arch btw) and now I am in the situation that my internal (but #removable) #keyboard works just fine in bios settings, to enter my LUKS password and in VTs, but as soon as I reach KDE it stops working. Also the mouse (part of the removable keyboard) stops working there, but works fine in BIOS. What do I do now? It worked fine 90min ago and I only upgraded chromium, firefox, fwupd and the #kernel. Tried downgrading the kernel but with no luck. What now?
