I've not (yet) done any investigation of this. Maybe a linux-6.12 thing? Note that build.log.xz decompresses to 95MB. ``` /var/tmp/portage/sys-libs/glibc-2.40-r7/work/build-x86-x86_64-pc-linux-gnu-nptl # cat ./misc/tst-pkey.out ../sysdeps/unix/sysv/linux/tst-pkey.c:284:

It's a kernel bug: https://sourceware.org/bugzilla/show_bug.cgi?id=32438#c5. Fixed by: 1) https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/tree/queue-6.12/x86-pkeys-change-caller-of-update_pkru_in_sigframe.patch 2) https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/tree/queue-6.12/x86-pkeys-ensure-updated-pkru-value-is-xrstor-d.patch I don't think there's anything for us to do given it's already queued for the next releases. I don't know enough about pkeys to know how serious the bug is and if it's worth an immediate backport and revbump or not.
The bug has been referenced in the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=c696519e6187e1ee6e7a419a73ce2c6aca18bca8 commit c696519e6187e1ee6e7a419a73ce2c6aca18bca8 Author: Mike Pagano <mpagano@gentoo.org> AuthorDate: 2024-12-11 22:39:58 +0000 Commit: Mike Pagano <mpagano@gentoo.org> CommitDate: 2024-12-11 22:39:58 +0000 sys-kernel/gentoo-sources: Bug fixes Add x86/pkeys fixes Bug: https://bugs.gentoo.org/946182 drm/display: Fix building with GCC 15 Bug: https://bugs.gentoo.org/946130 Signed-off-by: Mike Pagano <mpagano@gentoo.org> sys-kernel/gentoo-sources/Manifest | 3 ++ .../gentoo-sources/gentoo-sources-6.12.4-r1.ebuild | 37 ++++++++++++++++++++++ 2 files changed, 40 insertions(+)
