Hi all, Here's a complete test for the XFS buf I/O error race problem reported by Alex. An incomplete rfc of this test was previously posted here: http://oss.sgi.com/archives/xfs/2014-08/msg00261.html This version utilizes the recently posted log recovery delay mechanism. As such, this test only runs on kernels compiled with XFS debug support. The first patch updates the generic require sysfs helper to support global (i.e., non-device specific) sysfs attributes. Brian v1: - Use the log recovery delay mechanism to coordinate I/O failures with log recovery. rfc: http://oss.sgi.com/archives/xfs/2014-08/msg00261.html Brian Foster (2): xfstests/common: don't assume sysfs attrs all reside under test dev xfs/051: test buffer use after free race on I/O failure in XFS log recovery common/rc | 3 +- tests/xfs/011 | 2 +- tests/xfs/051 | 95 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/xfs/051.out | 2 ++ tests/xfs/group | 1 + 5 files changed, 100 insertions(+), 3 deletions(-) create mode 100755 tests/xfs/051 create mode 100644 tests/xfs/051.out -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe fstests" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
