### Neverallow rules
###
# There is no need to perform ioctl or advisory locking operations on
# property files. If this neverallow is being triggered, it is
# likely that the policy is using r_file_perms directly instead of
# the get_prop() macro.
neverallow domain property_type:file { ioctl lock };
# core_property_type should not be used for new properties or
# device specific properties. Properties with this attribute
# are readable to everyone, which is overly broad and should
# be avoided.
# New properties should have appropriate read / write access
# control rules written.
