iavf admin queue commands aren't thread-safe. Bugs surrounding this issue can manifest in a variety of ways but frequently pend_cmd is over written. Simultaneously executing commands can result in a misconfigured device or DPDK sleeping in a thread for 2 second.
Despite this limitation, vf commands may be executed from both iavf_dev_alarm_handler() in a control thread and the applications main thread. This is trivial to simulate in the testpmd application by creating a bond of vf's in active backup mode, and then turning the bond off and then on again repeatedly. Previously [1] was proposed as a potential solution, but this commit did not resolve all potential issues concerning the admin queue and has been reverted from the stable branch. I propose adding locks until a more complete solution is available. [1] commit cb5c1b91f76f ("net/iavf: add thread for event callbacks") Fixes: 48de41ca11f0 ("net/avf: enable link status update") Fixes: 84108425054a ("net/iavf: support asynchronous virtual channel message") Cc: sta...@dpdk.org Signed-off-by: Mike Pattrick <m...@redhat.com> --- v2: - Added locks around some iavf_execute_vf_cmd calls which were missed in v1 - Changed description to indicate that [1] was only reverted out of the stable branch. --- drivers/net/iavf/iavf.h | 1 + drivers/net/iavf/iavf_vchnl.c | 90 +++++++++++++++++++++++++++++++++++ 2 files changed, 91 insertions(+) diff --git a/drivers/net/iavf/iavf.h b/drivers/net/iavf/iavf.h index 1edebab8dc..aa18650ffa 100644 --- a/drivers/net/iavf/iavf.h +++ b/drivers/net/iavf/iavf.h @@ -262,6 +262,7 @@ struct iavf_info { struct iavf_qv_map *qv_map; /* queue vector mapping */ struct iavf_flow_list flow_list; rte_spinlock_t flow_ops_lock; + rte_spinlock_t aq_lock; struct iavf_parser_list rss_parser_list; struct iavf_parser_list dist_parser_list; struct iavf_parser_list ipsec_crypto_parser_list; diff --git a/drivers/net/iavf/iavf_vchnl.c b/drivers/net/iavf/iavf_vchnl.c index f92daf97f2..edb74edcac 100644 --- a/drivers/net/iavf/iavf_vchnl.c +++ b/drivers/net/iavf/iavf_vchnl.c @@ -554,7 +554,9 @@ iavf_enable_vlan_strip(struct iavf_adapter *adapter) args.in_args_size = 0; args.out_buffer = vf->aq_resp; args.out_size = IAVF_AQ_BUF_SZ; + rte_spinlock_lock(&vf->aq_lock); ret = iavf_execute_vf_cmd(adapter, &args, 0); + rte_spinlock_unlock(&vf->aq_lock); if (ret) PMD_DRV_LOG(ERR, "Failed to execute command of" " OP_ENABLE_VLAN_STRIPPING"); @@ -575,7 +577,9 @@ iavf_disable_vlan_strip(struct iavf_adapter *adapter) args.in_args_size = 0; args.out_buffer = vf->aq_resp; args.out_size = IAVF_AQ_BUF_SZ; + rte_spinlock_lock(&vf->aq_lock); ret = iavf_execute_vf_cmd(adapter, &args, 0); + rte_spinlock_unlock(&vf->aq_lock); if (ret) PMD_DRV_LOG(ERR, "Failed to execute command of" " OP_DISABLE_VLAN_STRIPPING"); @@ -604,7 +608,9 @@ iavf_check_api_version(struct iavf_adapter *adapter) args.out_buffer = vf->aq_resp; args.out_size = IAVF_AQ_BUF_SZ; + rte_spinlock_lock(&vf->aq_lock); err = iavf_execute_vf_cmd(adapter, &args, 0); + rte_spinlock_unlock(&vf->aq_lock); if (err) { PMD_INIT_LOG(ERR, "Fail to execute command of OP_VERSION"); return err; @@ -665,7 +671,9 @@ iavf_get_vf_resource(struct iavf_adapter *adapter) args.in_args = (uint8_t *)∩︀ args.in_args_size = sizeof(caps); + rte_spinlock_lock(&vf->aq_lock); err = iavf_execute_vf_cmd(adapter, &args, 0); + rte_spinlock_unlock(&vf->aq_lock); if (err) { PMD_DRV_LOG(ERR, @@ -710,7 +718,9 @@ iavf_get_supported_rxdid(struct iavf_adapter *adapter) args.out_buffer = vf->aq_resp; args.out_size = IAVF_AQ_BUF_SZ; + rte_spinlock_lock(&vf->aq_lock); ret = iavf_execute_vf_cmd(adapter, &args, 0); + rte_spinlock_unlock(&vf->aq_lock); if (ret) { PMD_DRV_LOG(ERR, "Failed to execute command of OP_GET_SUPPORTED_RXDIDS"); @@ -754,7 +764,9 @@ iavf_config_vlan_strip_v2(struct iavf_adapter *adapter, bool enable) args.in_args_size = sizeof(vlan_strip); args.out_buffer = vf->aq_resp; args.out_size = IAVF_AQ_BUF_SZ; + rte_spinlock_lock(&vf->aq_lock); ret = iavf_execute_vf_cmd(adapter, &args, 0); + rte_spinlock_unlock(&vf->aq_lock); if (ret) PMD_DRV_LOG(ERR, "fail to execute command %s", enable ?
