NetLabel: Allow passing the LSM domain as a shared pointer
Smack doesn't have the need to create a private copy of the LSM "domain" when setting NetLabel security attributes like SELinux, however, the current NetLabel code requires a private copy of the LSM "domain". This patches fixes that by letting the LSM determine how it wants to pass the domain value. * NETLBL_SECATTR_DOMAIN_CPY The current behavior, NetLabel assumes that the domain value is a copy and frees it when done * NETLBL_SECATTR_DOMAIN New, Smack-friendly behavior, NetLabel assumes that the domain value is a reference to a string managed by the LSM and does not free it when done Signed-off-by: Paul Moore <paul.moore@hp.com> Acked-by: James Morris <jmorris@namei.org> Signed-off-by: David S.
