Public bug reported: == Comment: #0 - Grgo Mariani <[email protected]> - 2025-06-23 03:21:06 == ---Problem Description--- Recently pkey module has been split into pkey, pkey-cca, pkey-ep11, pkey-pckmo and pkey-uv. This might cause problems for customers who use encrypted root directory with any of these as it requires these modules to be loaded with initrd. However listing the modules with lsinitramfs only shows the pkey module being loaded.
e.g. $ lsinitramfs /boot/initrd.img-$(uname -r) | grep pkey usr/lib/modules/6.14.0-22-generic/kernel/drivers/s390/crypto/pkey.ko.zst $ ls -la /lib/modules/$(uname -r)/kernel/drivers/s390/crypto | grep pkey -rw-r--r-- 1 root root 8003 May 21 09:38 pkey-cca.ko.zst -rw-r--r-- 1 root root 7304 May 21 09:38 pkey-ep11.ko.zst -rw-r--r-- 1 root root 15922 May 21 09:38 pkey.ko.zst -rw-r--r-- 1 root root 6207 May 21 09:38 pkey-pckmo.ko.zst -rw-r--r-- 1 root root 4643 May 21 09:38 pkey-uv.ko.zst ---uname output--- Linux SYSTEM 6.14.0-22-generic #22-Ubuntu SMP Wed May 21 13:32:46 UTC 2025 s390x s390x s390x GNU/Linux ---Additional Hardware Info--- CEX cards attached Contact Information = [email protected] [email protected] Machine Type = Manufacturer: IBM Type: 8561 Model: 701 T01 ---Debugger--- A debugger is not configured ---Steps to Reproduce--- Check the modules in the initrd $ lsinitramfs /boot/initrd.img-$(uname -r) | grep pkey and compare them with available modules $ ls -la /lib/modules/$(uname -r)/kernel/drivers/s390/crypto/ | grep pkey System Dump Info: The system is not configured to capture a system dump. Stack trace output: no Oops output: no == Comment: #1 - Ingo Franzki <[email protected]> - 2025-06-23 03:24:23 == FYI: You can use the Dracut config file from https://github.com/ibm-s390-linux/s390-tools/blob/master/zkey/dracut/99-pkey.conf to get all required modules, tools and files into initramfs. == Comment: #4 - Ingo Franzki <[email protected]> - 2025-06-23 08:01:41 == In case initramfs-tools is still being used then https://github.com/ibm-s390-linux/s390-tools/blob/master/zkey/initramfs/hooks/s390-tools-zkey can be used. ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Skipper Bug Screeners (skipper-screen-team) Status: Confirmed ** Tags: architecture-s3903164 bugnameltc-213961 severity-high targetmilestone-inin2504 ** Tags added: architecture-s3903164 bugnameltc-213961 severity-high targetmilestone-inin2504 ** Changed in: ubuntu Assignee: (unassigned) => Skipper Bug Screeners (skipper-screen-team) ** Package changed: ubuntu => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2115718 Title: [UBUNTU 25.04] not all pkey modules available in initrd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2115718/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
