XFS status update for June 2010

The month of June saw a few important bug fixes for the Linux 2.6.35 release candidates. That includes ensuring that files used for the swapext ioctl are writable to the user, and doing proper validation of inodes coming from untrusted sources, such as NFS exporting and the open by handle system calls. The main work however has been focused on development for the Linux 2.6.36 merge window, including merging various patches that have been out on the mainline list for a long time. Highlights include further performance improvements for sync heavy metadata workloads, stack space reduction in the writeback path and improvements of the XFS tracing infrastructure. Also after some discussion the remaining hooks for DMAPI are going
to be dropped in mainline. As a replacement a tree containing
full DMAPI support with a slightly cleaner XFS interaction will be hosted by SGI.

On the userspace side June was a rather slow month, with no updates to xfsprogs and xfsdump at all, and just one new test case and a cleanup applied to xfstests.
