Reproducing: 1. mount -t reiserfs /dev/blah /tmp -o noatime 2. FEATURES=makecheck emerge glibc The test is definitely in the latest glibcs (sys-libs/glibc-2.3.4.20050125-r1 and above), not sure if it's in earlier ones. This is probably true for more systems than you'd think, since it's the default for the handbook. glibc does a test to see if atimes are enabled (in libio/tst-atime.c). It first tries to check if noatime is set as a mount option, which is clever since the test is guaranteed to fail when noatime is on. What isn't clever is that it uses statvfs(2) to do this, despite the fact that the man page mentions that any of the given values can be undefined. I have a program that can print this struct, available here: http://linux.ferret.vze.com/statvfs-tester.c For a fs with noatime enabled, sv.f_flag should bitwise OR with 1024 (i.e. the tenth bit from the right should be 1) Suggested fix: no idea. It isn't a bug in reiserfs, really, since the man page says populating the struct isn't necessary, but it would be nice for reiserfs to do this. So glibc's test suite is slightly broken, perhaps it needs to display a warning and pass the test if sv.f_flag == 0, or maybe it needs to find out by some other method if the filesystem is mounted with noatime option. kernel version is 2.6.10, reiserfs version used is 3.6

known issue ... older glibc's had an ugly ugly hack in them to that tried to re-mount w/out noatime, but that was quickly punted
I don't see any great ways of resolving this without pretty much disabling the test entirely. There just is no way of determining whether a filesystem has no mount options enabled, or has just not bothered to inform statvfs. I've mentioned this to some reiserfs guys who are going to look into making the statvfs work properly. other than that I'm going to resolve this as LATER (I think that's the right resolution to use?) since there are a lot of tests AFTER this one that fail too. Maybe some day when I'm bored I'll fix the WHOLE test suite.
re-opening to mark as dup of bug #86515, bringing all the "glibc fails atime test" bugs together
marking dup as noted above :) *** This bug has been marked as a duplicate of 86515 ***
