TEST SUITE:
|
|
|
|
The directory cgroup_xattr contains the tests related to extended
|
|
attributes in cgroup filesystem.
|
|
|
|
WARNING:
|
|
|
|
This test can cause a kernel panic due to a bug in kernels prior to 3.8.
|
|
It was fixed by kernel upstream commit
|
|
712317ad97f41e738e1a19aa0a6392a78a84094e:
|
|
|
|
"We should store file xattrs in struct cfent instead of struct cftype,
|
|
because cftype is a type while cfent is object instance of cftype."
|
|
|
|
TESTS AIM:
|
|
|
|
The aim of the tests is to check the extended attributes in cgroup
|
|
filesystem. This feature was added in Linux 3.7 to allow attaching runtime
|
|
meta information to cgroups and everything they model (services, apps, vms)
|
|
and can easily be shared among applications.
|
|
|
|
Test mounts as many subsystems as possible (cpu, cpuset, ...) in the
|
|
cgroup tmp directory and creates one more hierarchy. Then sets extended
|
|
attributes to all files in cgroup fs and subsequently reads the file's
|
|
extended attributes back, checking values during the process.
