An updated disco master-next tree now shows the following: $ git log --oneline | grep -m 1 "do nosimd fallback manually" ccfd9be crypto: vmx - ghash: do nosimd fallback manually $ git describe --tags --contains ccfd9be Ubuntu-5.0.0-26.27~34 $ git log --oneline | grep -m 1 "always increment IV as quadword" b5df7b3 crypto: vmx - CTR: always increment IV as quadword $ git describe --tags --contains b5df7b3 Ubuntu-5.0.0-26.27~394 $ git log --oneline | grep -m 1 "fix copy-paste error in CTR mode" 6cef65e crypto: vmx - fix copy-paste error in CTR mode $ git describe --tags --contains 6cef65e Ubuntu-5.0.0-24.25~116
That kernel "Ubuntu-5.0.0-26" incl. everything needed and 5.0.0.27 is in disco proposed: linux-generic | 5.0.0.27.28 | disco-proposed | s390x Hence, would you mind re-trying with the latest disco-proposed kernel? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1841984 Title: [Backport] Crypto VMX Fixes Status in The Ubuntu-power-systems project: In Progress Status in linux package in Ubuntu: In Progress Bug description: Ubuntu Disco is missing the fix for "5c380d623ed3 - crypto: vmx - Add support for VMS instructions by ASM (4 years, 5 months ago) <Leonidas S. Barbosa>" ... which is fixed by 'crypto: vmx - fix copy-paste error in CTR mode', it fixes a couple of incorrect branch targets, and usage of an incorrect vector assembly instruction. The others two patches ("crypto: vmx - CTR: always increment IV as quadword ", "crypto: vmx - ghash: do nosimd fallback manually ") fixes for ghash replaces the fallback mechanism that is used on powerpc an operation is required to operate in interrupt context. Not having these patches might lead to data integrity issues. patches crypto: vmx - fix copy-paste error in CTR mode https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dcf7b48212c0fab7df69e84fab22d6cb7c8c0fb9 crypto: vmx - CTR: always increment IV as quadword https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=009b30ac7444c17fae34c4f435ebce8e8e2b3250 crypto: vmx - ghash: do nosimd fallback manually https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=357d065a44cdd77ed5ff35155a989f2a763e96ef To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1841984/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
