From a8e161f4c38c371974319359165d544604e06b78 Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 24 Feb 2012 18:01:27 +0100 Subject: S390: 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) Signed-off-by: David Howells Acked-by: dan@danny.cz Cc: Carsten Otte Reviewed-by: Christian Borntraeger Cc: linux-s390@vger.kernel.org Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky Signed-off-by: Greg Kroah-Hartman --- arch/s390/Kconfig | 3 +++ 1 file changed, 3 insertions(+) (limited to 'arch/s390') diff --git a/arch/s390/Kconfig b/arch/s390/Kconfig index c03fef7..9b922b1 100644 --- a/arch/s390/Kconfig +++ b/arch/s390/Kconfig @@ -228,6 +228,9 @@ config COMPAT config SYSVIPC_COMPAT def_bool y if COMPAT && SYSVIPC +config KEYS_COMPAT + def_bool y if COMPAT && KEYS + config AUDIT_ARCH def_bool y -- cgit v1.1
