Subject: fallocate() on XFS clobbers S*ID-bits
Date: Thu, 7 Oct 2010 20:34:19 +0200 [thread overview]
Message-ID: <20101007183418.GC5621@incendiary.meterriblecrew.net> (raw)
Hello.
I (with support from Cc'ed Ciaran) just noticed some odd behaviour with
fallocate() on XFS. After open()ing some file and setting it S*ID via
fchmod(), S*ID bits vanish after calling fallocate() — as supposed to
for non-root users, but it also happens for root.
Is this intended behaviour or did we spot a bug here?
At least on ext2 it works as expected, thus I guess it's the latter one.
I'm running v2.6.35.7 vanilla-kernel, but diffing fs/xfs to master
doesn't seem to address this issue.
