Audit: use new LSM hooks instead of SELinux exports
Stop using the following exported SELinux interfaces: selinux_get_inode_sid(inode, sid) selinux_get_ipc_sid(ipcp, sid) selinux_get_task_sid(tsk, sid) selinux_sid_to_string(sid, ctx, len) kfree(ctx) and use following generic LSM equivalents respectively: security_inode_getsecid(inode, secid) security_ipc_getsecid*(ipcp, secid) security_task_getsecid(tsk, secid) security_sid_to_secctx(sid, ctx, len) security_release_secctx(ctx, len) Call security_release_secctx only if security_secid_to_secctx succeeded.
