Have you tested this patch on fedora libglvnd ? I don't know if BTI is enabled in which fedora version, but I might backport the patch for f37+ unless there is a new release upstream... So I added that patch to my to the libglvnd SRPM in my local repo. Janne Grunau and Linus Torvalds (yes really) both confirmed that it worked. https://www.leifliddy.com/asahi-linux/36/source/SRPMS/ https://www.leifliddy.com/asahi-linux/36/aarch64/ I don't have an m2 macbook to test on so I can't personally confirm it. But I would consider both Janne and Linus to be reliable sources. The dmesg logs posted showed the following: CPU features: detected: Branch Target Identification > but I might backport the patch for f37+ unless there is a new release upstream... That would definitely work. I mean I could ask the project maintainers if they could just make a new release (that included that commit) But you would probably have more pull then I would. FEDORA-2022-fb41fa9ea6 has been submitted as an update to Fedora 38. https://bodhi.fedoraproject.org/updates/FEDORA-2022-fb41fa9ea6 FEDORA-2022-db6c2e9180 has been submitted as an update to Fedora 37. https://bodhi.fedoraproject.org/updates/FEDORA-2022-db6c2e9180 FEDORA-2022-fb41fa9ea6 has been pushed to the Fedora 38 stable repository. If problem still persists, please make note of it in this bug report. Okay backported for f36+ For some reason I cannot link the bug, so here is the bodhi update: https://bodhi.fedoraproject.org/updates/FEDORA-2022-8890cf0609 Thanks for the report and feedbacks. FEDORA-2022-db6c2e9180 has been pushed to the Fedora 37 stable repository. If problem still persists, please make note of it in this bug report. |
