New Revision: 234507
URL: http://svn.freebsd.org/changeset/base/234507
Log:
Fix the following compilation warnings in sys/contrib/rdma/rdma_cma.c:
sys/contrib/rdma/rdma_cma.c:1259:8: error: case value not in enumerated
type 'enum iw_cm_event_status' [-Werror,-Wswitch]
case ECONNRESET:
^
@/sys/errno.h:118:20: note: expanded from macro 'ECONNRESET'
#define ECONNRESET 54 /* Connection reset by peer */
^
sys/contrib/rdma/rdma_cma.c:1263:8: error: case value not in enumerated
type 'enum iw_cm_event_status' [-Werror,-Wswitch]
case ETIMEDOUT:
^
@/sys/errno.h:124:19: note: expanded from macro 'ETIMEDOUT'
#define ETIMEDOUT 60 /* Operation timed out */
^
sys/contrib/rdma/rdma_cma.c:1260:8: error: case value not in enumerated
type 'enum iw_cm_event_status' [-Werror,-Wswitch]
case ECONNREFUSED:
^
@/sys/errno.h:125:22: note: expanded from macro 'ECONNREFUSED'
#define ECONNREFUSED 61 /* Connection refused */
^
This is because the switch uses iw_cm_event::status, which is an enum
iw_cm_event_status, while ECONNRESET, ETIMEDOUT and ECONNREFUSED are
just plain defines from errno.h.
It looks like there is only one use of any of the enumeration values of
iw_cm_event_status, in:
sys/contrib/rdma/rdma_iwcm.c: if (iw_event->status ==
IW_CM_EVENT_STATUS_ACCEPTED) {
So messing around with the enum definitions to fix the warning seems too
disruptive; the simplest fix is to cast the argument of the switch to
int.
