For the transitions: RTS -> RTS: IB_QP_CUR_STATE should be allowed for all transports SQD -> SQD: IB_QP_CUR_STATE should never be allowed Signed-off-by: Dotan Barak Signed-off-by: Roland Dreier --- diff --git a/drivers/infiniband/core/verbs.c b/drivers/infiniband/core/verbs.c index c69334dc80..cae0845f47 100644 --- a/drivers/infiniband/core/verbs.c +++ b/drivers/infiniband/core/verbs.c @@ -366,10 +366,12 @@ static const struct { .opt_param = { [IB_QPT_UD] = (IB_QP_CUR_STATE | IB_QP_QKEY), - [IB_QPT_UC] = (IB_QP_ACCESS_FLAGS | + [IB_QPT_UC] = (IB_QP_CUR_STATE | + IB_QP_ACCESS_FLAGS | IB_QP_ALT_PATH | IB_QP_PATH_MIG_STATE), - [IB_QPT_RC] = (IB_QP_ACCESS_FLAGS | + [IB_QPT_RC] = (IB_QP_CUR_STATE | + IB_QP_ACCESS_FLAGS | IB_QP_ALT_PATH | IB_QP_PATH_MIG_STATE | IB_QP_MIN_RNR_TIMER), @@ -419,7 +421,6 @@ static const struct { [IB_QPT_UD] = (IB_QP_PKEY_INDEX | IB_QP_QKEY), [IB_QPT_UC] = (IB_QP_AV | - IB_QP_CUR_STATE | IB_QP_ALT_PATH | IB_QP_ACCESS_FLAGS | IB_QP_PKEY_INDEX | @@ -431,7 +432,6 @@ static const struct { IB_QP_RNR_RETRY | IB_QP_MAX_QP_RD_ATOMIC | IB_QP_MAX_DEST_RD_ATOMIC | - IB_QP_CUR_STATE | IB_QP_ALT_PATH | IB_QP_ACCESS_FLAGS | IB_QP_PKEY_INDEX |
