[Bug 1776967] Re: glibc pkeys test fail on powerpc
This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you! ** Tags added: verification-needed-bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776967 Title: glibc pkeys test fail on powerpc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1776967/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It looks like the kernel fixes might not be ready quite yet, so I'm temporarily disabling CONFIG_PPC_MEM_KEYS in our ppc64el kernel. ** Changed in: linux (Ubuntu Cosmic) Status: Confirmed => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776967 Title: glibc pkeys test fail on powerpc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1776967/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1776967] Re: glibc pkeys test fail on powerpc
Florian, thanks for the heads-up and for pursuing this. I read some of the links pointed out in that bug, and I see there is much to improve yet, and 4.17 might not have the best pkeys story for powerpc. Maybe we should just disable that test in the meantime. About the particular problem we saw here in our case: FAIL: misc/tst-pkey original exit status 1 error: ../sysdeps/unix/sysv/linux/tst-pkey.c:200: pkey_alloc: No space left on device error: 1 test failures Running this on a system I got hold onto, I got the same issue. Likely, this is due to pkey_disabled from arch/powerpc/include/asm/pkeys.h:mm_pkey_alloc, which would be the case as in arch/powerpc/mm/pkeys.c:pkey_initialize: if (!pkey_mmu_enabled() || radix_enabled() || !pkeys_total) static_branch_enable(&pkey_disabled); else static_branch_disable(&pkey_disabled); I don't think EINVAL should be returned instead. Returning ENOSPC in such a case seems reasonable, and any pkey code should be able to handle that case. So, one more thing to fixup in the tests expectations.

Upstream bug: https://sourceware.org/bugzilla/show_bug.cgi?id=23202 There are three issues here: The kernel implementation in 4.17 was buggy: pkey_set and pkey_get weren't implement in glibc, and the misc /tst-pkeys has some incorrect test expectations. ** Bug watch added: Sourceware.org Bugzilla #23202 https://sourceware.org/bugzilla/show_bug.cgi?id=23202 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776967 Title: glibc pkeys test fail on powerpc To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1776967/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
