Hide Forgot
I am seeing on Rawhide with # semodule -d unconfined in permissive mode AVC msgs like these type=AVC msg=audit(1296644461.791:190): avc: denied { write } for pid=4435 comm="crond" name="user" dev=cgroup ino=21207 scontext=system_u:system_r:crond_t:s0-s0:c0.c1023 tcontext=system_u:object_r:cgroup_t:s0 tclass=dir ---- time->Wed Feb 2 12:01:01 2011 type=PATH msg=audit(1296644461.792:191): item=0 name="/sys/fs/cgroup/systemd/user/root/5/tasks" inode=63024 dev=00:13 mode=0100644 ouid=0 ogid=0 rdev=00:00 obj=system_u:object_r:cgroup_t:s0 type=AVC msg=audit(1296644461.790:185): avc: denied { getattr } for pid=4435 comm="crond" path="/var/run/user" dev=tmpfs ino=12597 scontext=system_u:system_r:crond_t:s0-s0:c0.c1023 tcontext=system_u:object_r:var_auth_t:s0 tclass=dir ---- time->Wed Feb 2 12:01:01 2011 type=PATH msg=audit(1296644461.790:186): item=0 name="/var/run/user/.pam-systemd-lock" inode=21204 dev=00:23 mode=0100600 ouid=0 ogid=500 rdev=00:00 obj=system_u:object_r:var_auth_t:s0 ------------- allow crond_t cgroup_t:dir { write rmdir setattr read remove_name create add_name }; allow crond_t cgroup_t:file { write read getattr open setattr }; allow crond_t var_auth_t:dir { search setattr read create write getattr rmdir remove_name open add_name }; allow crond_t var_auth_t:file { read write open lock }; ------------ The log is attached.

Well, probably relates with > just wanted to let everybody know that I reverted the logic in > pam_sytemd which automatically creates a cgroup in the 'cpu' hierarchy > for every user/session, since it makes it impossible to use RT > scheduling from user/session processes then.
Seems like something we should allow., I believe we want to allow cron to setup the cgroups before launching a job for a user.
Fixed in selinux-policy-3.9.13-9.fc15.
