Also the commit introduces range check in\n i40e_vc_enable_queues_msg function.\n\nSigned-off-by: Arkady Gilinsky <arkady.gilinsky@harmonicinc.com>\n---\n drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c | 23 ++++++++++++++++------\n drivers/net/ethernet/intel/iavf/iavf_virtchnl.c | 6 ++++--\n 2 files changed, 21 insertions(+), 8 deletions(-)\n\n-- \n2.11.0", "diff": "diff --git a/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c b/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c\nindex 3d2440838822..c650eb91982a 100644\n--- a/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c\n+++ b/drivers/net/ethernet/intel/i40e/i40e_virtchnl_pf.c\n@@ -2352,13 +2352,22 @@ static int i40e_vc_enable_queues_msg(struct i40e_vf *vf, u8 *msg)\n \t\tgoto error_param;\n \t}\n \n-\t/* Use the queue bit map sent by the VF */\n-\tif (i40e_ctrl_vf_rx_rings(pf->vsi[vf->lan_vsi_idx], vqs->rx_queues,\n+\tif ((vqs->rx_queues == 0 && vqs->tx_queues == 0) ||\n+\t vqs->rx_queues > I40E_MAX_VF_QUEUES ||\n+\t vqs->tx_queues > I40E_MAX_VF_QUEUES) {\n+\t\taq_ret = I40E_ERR_PARAM;\n+\t\tgoto error_param;\n+\t}\n+\n+\t/* Build the queue bit map from value sent by the VF */\n+\tif (i40e_ctrl_vf_rx_rings(pf->vsi[vf->lan_vsi_idx],\n+\t\t\t\t BIT(vqs->rx_queues) - 1,\n \t\t\t\t true)) {\n \t\taq_ret = I40E_ERR_TIMEOUT;\n \t\tgoto error_param;\n \t}\n-\tif (i40e_ctrl_vf_tx_rings(pf->vsi[vf->lan_vsi_idx], vqs->tx_queues,\n+\tif (i40e_ctrl_vf_tx_rings(pf->vsi[vf->lan_vsi_idx],\n+\t\t\t\t BIT(vqs->tx_queues) - 1,\n \t\t\t\t true)) {\n \t\taq_ret = I40E_ERR_TIMEOUT;\n \t\tgoto error_param;\n@@ -2416,13 +2425,15 @@ static int i40e_vc_disable_queues_msg(struct i40e_vf *vf, u8 *msg)\n \t\tgoto error_param;\n \t}\n \n-\t/* Use the queue bit map sent by the VF */\n-\tif (i40e_ctrl_vf_tx_rings(pf->vsi[vf->lan_vsi_idx], vqs->tx_queues,\n+\t/* Build the queue bit map from value sent by the VF */\n+\tif (i40e_ctrl_vf_tx_rings(pf->vsi[vf->lan_vsi_idx],\n+\t\t\t\t BIT(vqs->tx_queues) - 1,\n \t\t\t\t false)) {\n \t\taq_ret = I40E_ERR_TIMEOUT;\n \t\tgoto error_param;\n \t}\n-\tif (i40e_ctrl_vf_rx_rings(pf->vsi[vf->lan_vsi_idx], vqs->rx_queues,\n+\tif (i40e_ctrl_vf_rx_rings(pf->vsi[vf->lan_vsi_idx],\n+\t\t\t\t BIT(vqs->rx_queues) - 1,\n \t\t\t\t false)) {\n \t\taq_ret = I40E_ERR_TIMEOUT;\n \t\tgoto error_param;\ndiff --git a/drivers/net/ethernet/intel/iavf/iavf_virtchnl.c b/drivers/net/ethernet/intel/iavf/iavf_virtchnl.c\nindex c46770eba320..271f144bf05b 100644\n--- a/drivers/net/ethernet/intel/iavf/iavf_virtchnl.c\n+++ b/drivers/net/ethernet/intel/iavf/iavf_virtchnl.c\n@@ -308,7 +308,8 @@ void iavf_enable_queues(struct iavf_adapter *adapter)\n \t}\n \tadapter->current_op = VIRTCHNL_OP_ENABLE_QUEUES;\n \tvqs.vsi_id = adapter->vsi_res->vsi_id;\n-\tvqs.tx_queues = BIT(adapter->num_active_queues) - 1;\n+\t/* Send the queues number to PF */\n+\tvqs.tx_queues = adapter->num_active_queues;\n \tvqs.rx_queues = vqs.tx_queues;\n \tadapter->aq_required &= ~IAVF_FLAG_AQ_ENABLE_QUEUES;\n \tiavf_send_pf_msg(adapter, VIRTCHNL_OP_ENABLE_QUEUES,\n@@ -333,7 +334,8 @@ void iavf_disable_queues(struct iavf_adapter *adapter)\n \t}\n \tadapter->current_op = VIRTCHNL_OP_DISABLE_QUEUES;\n \tvqs.vsi_id = adapter->vsi_res->vsi_id;\n-\tvqs.tx_queues = BIT(adapter->num_active_queues) - 1;\n+\t/* Send the queues number to PF */\n+\tvqs.tx_queues = adapter->num_active_queues;\n \tvqs.rx_queues = vqs.tx_queues;\n \tadapter->aq_required &= ~IAVF_FLAG_AQ_DISABLE_QUEUES;\n \tiavf_send_pf_msg(adapter, VIRTCHNL_OP_DISABLE_QUEUES,\n", "prefixes": [ "net" ] }
