Hi all, It would be very useful if system administrators could set properties for a given xfs filesystem to control its behavior. This we can do easily and extensibly by setting ATTR_ROOT (aka "trusted") extended attributes on the root directory. To prevent this from becoming a weird free for all, let's add some library and tooling support so that sysadmins simply run the xfs_property program to administer these properties. If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. This has been running on the djcloud for months with no problems. Enjoy! Comments and questions are, as always, welcome. --D xfsprogs git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfsprogs-dev.git/log/?h=filesystem-properties fstests git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfstests-dev.git/log/?h=filesystem-properties --- Commits in this patchset: * xfs: functional testing for filesystem properties --- common/config | 1 common/xfs | 14 ++++- doc/group-names.txt | 1 tests/generic/062 | 4 + tests/xfs/1886 | 137 +++++++++++++++++++++++++++++++++++++++++++++++++++ tests/xfs/1886.out | 53 ++++++++++++++++++++ tests/xfs/1887 | 122 +++++++++++++++++++++++++++++++++++++++++++++ tests/xfs/1887.out | 46 +++++++++++++++++ tests/xfs/1888 | 66 +++++++++++++++++++++++++ tests/xfs/1888.out | 9 +++ tests/xfs/1889 | 63 +++++++++++++++++++++++ tests/xfs/1889.out | 8 +++ 12 files changed, 522 insertions(+), 2 deletions(-) create mode 100755 tests/xfs/1886 create mode 100644 tests/xfs/1886.out create mode 100755 tests/xfs/1887 create mode 100644 tests/xfs/1887.out create mode 100755 tests/xfs/1888 create mode 100644 tests/xfs/1888.out create mode 100755 tests/xfs/1889 create mode 100644 tests/xfs/1889.out
