KEYS: Enable the compat keyctl wrapper on s390x
commit 1d057720609ed052a6371fe1d53300e5e6328e94 upstream.
Enable the compat keyctl wrapper on s390x so that 32-bit s390 userspace can
call the keyctl() syscall.
There's an s390x assembly wrapper that truncates all the register values to
32-bits and this then calls compat_sys_keyctl() - but the latter only exists if
CONFIG_KEYS_COMPAT is enabled, and the s390 Kconfig doesn't enable it.
Without this patch, 32-bit calls to the keyctl() syscall are given an ENOSYS
error:
[root@devel4 ~]# keyctl show
Session Keyring
-3: key inaccessible (Function not implemented)
