From c2c523189634c54cb99ce452a14c46d02cc4d2de Mon Sep 17 00:00:00 2001 From: Conor Walsh Date: Tue, 20 Oct 2020 10:02:47 +0000 Subject: [PATCH] net/ixgbe: check switch domain allocation result The return value of rte_eth_switch_domain_alloc() was not being checked within ixgbe_pf_host_init() which caused a coverity issue. If the call fails a warning is logged using PMD_INIT_LOG() and *vfinfo is free'd. ixgbe_pf_host_init() now has a return value which is checked in eth_ixgbe_dev_init() Coverity issue: 362795 Fixes: cf80ba6e2038 ("net/ixgbe: add support for representor ports") Cc: stable@dpdk.org Signed-off-by: Conor Walsh Acked-by: Haiyue Wang --- drivers/net/ixgbe/ixgbe_ethdev.c | 11 +++++++++-- drivers/net/ixgbe/ixgbe_ethdev.h | 2 +- drivers/net/ixgbe/ixgbe_pf.c | 16 +++++++++++++--- 3 files changed, 23 insertions(+), 6 deletions(-) diff --git a/drivers/net/ixgbe/ixgbe_ethdev.c b/drivers/net/ixgbe/ixgbe_ethdev.c index 00101c2eec..913c45366a 100644 --- a/drivers/net/ixgbe/ixgbe_ethdev.c +++ b/drivers/net/ixgbe/ixgbe_ethdev.c @@ -1077,7 +1077,7 @@ eth_ixgbe_dev_init(struct rte_eth_dev *eth_dev, void *init_params __rte_unused) IXGBE_DEV_PRIVATE_TO_BW_CONF(eth_dev->data->dev_private); uint32_t ctrl_ext; uint16_t csum; - int diag, i; + int diag, i, ret; PMD_INIT_FUNC_TRACE(); @@ -1256,7 +1256,14 @@ eth_ixgbe_dev_init(struct rte_eth_dev *eth_dev, void *init_params __rte_unused) memset(hwstrip, 0, sizeof(*hwstrip)); /* initialize PF if max_vfs not zero */ - ixgbe_pf_host_init(eth_dev); + ret = ixgbe_pf_host_init(eth_dev); + if (ret) { + rte_free(eth_dev->data->mac_addrs); + eth_dev->data->mac_addrs = NULL; + rte_free(eth_dev->data->hash_mac_addrs); + eth_dev->data->hash_mac_addrs = NULL; + return ret; + } ctrl_ext = IXGBE_READ_REG(hw, IXGBE_CTRL_EXT); /* let hardware know driver is loaded */ diff --git a/drivers/net/ixgbe/ixgbe_ethdev.h b/drivers/net/ixgbe/ixgbe_ethdev.h index 33905f7136..0132fb8db7 100644 --- a/drivers/net/ixgbe/ixgbe_ethdev.h +++ b/drivers/net/ixgbe/ixgbe_ethdev.h @@ -717,7 +717,7 @@ void ixgbe_vlan_hw_filter_disable(struct rte_eth_dev *dev); void ixgbe_vlan_hw_strip_config(struct rte_eth_dev *dev); -void ixgbe_pf_host_init(struct rte_eth_dev *eth_dev); +int ixgbe_pf_host_init(struct rte_eth_dev *eth_dev); void ixgbe_pf_host_uninit(struct rte_eth_dev *eth_dev); diff --git a/drivers/net/ixgbe/ixgbe_pf.c b/drivers/net/ixgbe/ixgbe_pf.c index ed5f96b1a4..4e25b1e72e 100644 --- a/drivers/net/ixgbe/ixgbe_pf.c +++ b/drivers/net/ixgbe/ixgbe_pf.c @@ -66,7 +66,7 @@ ixgbe_mb_intr_setup(struct rte_eth_dev *dev) return 0; } -void ixgbe_pf_host_init(struct rte_eth_dev *eth_dev) +int ixgbe_pf_host_init(struct rte_eth_dev *eth_dev) { struct ixgbe_vf_info **vfinfo = IXGBE_DEV_PRIVATE_TO_P_VFDATA(eth_dev->data->dev_private); @@ -78,19 +78,27 @@ void ixgbe_pf_host_init(struct rte_eth_dev *eth_dev) IXGBE_DEV_PRIVATE_TO_HW(eth_dev->data->dev_private); uint16_t vf_num; uint8_t nb_queue; + int ret = 0; PMD_INIT_FUNC_TRACE(); RTE_ETH_DEV_SRIOV(eth_dev).active = 0; vf_num = dev_num_vf(eth_dev); if (vf_num == 0) - return; + return ret; *vfinfo = rte_zmalloc("vf_info", sizeof(struct ixgbe_vf_info) * vf_num, 0); if (*vfinfo == NULL) rte_panic("Cannot allocate memory for private VF data\n"); - rte_eth_switch_domain_alloc(&(*vfinfo)->switch_domain_id); + ret = rte_eth_switch_domain_alloc(&(*vfinfo)->switch_domain_id); + if (ret) { + PMD_INIT_LOG(ERR, + "failed to allocate switch domain for device %d", ret); + rte_free(*vfinfo); + *vfinfo = NULL; + return ret; + } memset(mirror_info, 0, sizeof(struct ixgbe_mirror_info)); memset(uta_info, 0, sizeof(struct ixgbe_uta_info)); @@ -118,6 +126,8 @@ void ixgbe_pf_host_init(struct rte_eth_dev *eth_dev) /* set mb interrupt mask */ ixgbe_mb_intr_setup(eth_dev); + + return ret; } void ixgbe_pf_host_uninit(struct rte_eth_dev *eth_dev) -- 2.20.1
