** Patch added: "fix for bionic" https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1853193/+attachment/5388335/+files/glibc_2.27-3ubuntu1.1.debdiff
** Description changed: + [Impact] + When tested against newer versions of linux, glibc tests will fail as it makes some assumptions about supportead features on the kernel. + + [Fix] + Do not run the test that checks that copy_file_range will fail with EXDEV when done across devices. + + [Test case] + Build glibc and run its tests on linux 5.3. + + [Regression potential] + The same test is being ignored right now, we risk ignoring a failure on an older version of linux, like 4.15. However, that could happen because the feature is backported to said kernel. And we are currently ignoring the failure anyway. + + =================================== + copy_file_range on linux 5.3 now works across devices, so EXDEV is not returned anymore on those cases. glibc, however, tests that is the case and its autopkgtest fails, then, when running on linux 5.3. glibc 2.30 does not fail in that case anymore, so eoan glibc works fine on linux 5.3. However, the change on glibc 2.30 was to remove its userspace emulation entirely, and require users to fallback on their own. https://sourceware.org/bugzilla/show_bug.cgi?id=24744 Linux commit 5dae222a5ff0c269730393018a5539cc970a4726. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1853193 Title: copy_file_range test fails with linux 5.3+ on bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1853193/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
