From f35eaaca5f5f09b48f5d96adbaccc4484aa6e058 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Wed, 2 Oct 2019 10:17:43 -0700 Subject: [PATCH] net/bnxt: fix crash in secondary process The secondary process should not modify device state when init is called. The pci device information pointed to by dev_private pointer is not correct in secondary process. Fixes: b7778e8a1c00 ("net/bnxt: refactor to properly allocate resources for PF/VF") Cc: stable@dpdk.org Signed-off-by: Stephen Hemminger Acked-by: Ajit Khaparde --- drivers/net/bnxt/bnxt_ethdev.c | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-) diff --git a/drivers/net/bnxt/bnxt_ethdev.c b/drivers/net/bnxt/bnxt_ethdev.c index 0159be3462..5985963bf7 100644 --- a/drivers/net/bnxt/bnxt_ethdev.c +++ b/drivers/net/bnxt/bnxt_ethdev.c @@ -521,6 +521,7 @@ static int bnxt_init_nic(struct bnxt *bp) static int bnxt_dev_info_get_op(struct rte_eth_dev *eth_dev, struct rte_eth_dev_info *dev_info) { + struct rte_pci_device *pdev = RTE_DEV_TO_PCI(eth_dev->device); struct bnxt *bp = eth_dev->data->dev_private; uint16_t max_vnics, i, j, vpool, vrxq; unsigned int max_rx_rings; @@ -536,7 +537,8 @@ static int bnxt_dev_info_get_op(struct rte_eth_dev *eth_dev, /* PF/VF specifics */ if (BNXT_PF(bp)) - dev_info->max_vfs = bp->pdev->max_vfs; + dev_info->max_vfs = pdev->max_vfs; + max_rx_rings = RTE_MIN(bp->max_rx_rings, bp->max_stat_ctx); /* For the sake of symmetry, max_rx_queues = max_tx_queues */ dev_info->max_rx_queues = max_rx_rings; @@ -4488,12 +4490,6 @@ bnxt_dev_init(struct rte_eth_dev *eth_dev) if (version_printed++ == 0) PMD_DRV_LOG(INFO, "%s\n", bnxt_version); - rte_eth_copy_pci_info(eth_dev, pci_dev); - - bp = eth_dev->data->dev_private; - - bp->dev_stopped = 1; - eth_dev->dev_ops = &bnxt_dev_ops; eth_dev->rx_pkt_burst = &bnxt_recv_pkts; eth_dev->tx_pkt_burst = &bnxt_xmit_pkts; @@ -4505,6 +4501,12 @@ bnxt_dev_init(struct rte_eth_dev *eth_dev) if (rte_eal_process_type() != RTE_PROC_PRIMARY) return 0; + rte_eth_copy_pci_info(eth_dev, pci_dev); + + bp = eth_dev->data->dev_private; + + bp->dev_stopped = 1; + if (bnxt_vf_pciid(pci_dev->id.device_id)) bp->flags |= BNXT_FLAG_VF; -- 2.20.1
