From 588ae95e79834495f78192fc6bb3ae14c152439f Mon Sep 17 00:00:00 2001 From: Junyu Jiang Date: Tue, 29 Oct 2019 02:23:41 +0000 Subject: [PATCH] net/bonding: fix port ID check Port validation should be prior to getting device data to avoid segment fault. This patch fixed the segment fault caused by invalid port using. Fixes: 6d72657ce379 ("net/bonding: add other aggregator modes") Fixes: 112891cd27e5 ("net/bonding: add dedicated HW queues for LACP control") Cc: stable@dpdk.org Signed-off-by: Junyu Jiang Acked-by: Chas Williams --- drivers/net/bonding/rte_eth_bond_8023ad.c | 32 ++++++++++++++++------- 1 file changed, 22 insertions(+), 10 deletions(-) diff --git a/drivers/net/bonding/rte_eth_bond_8023ad.c b/drivers/net/bonding/rte_eth_bond_8023ad.c index badcd109ae..05b3004c4c 100644 --- a/drivers/net/bonding/rte_eth_bond_8023ad.c +++ b/drivers/net/bonding/rte_eth_bond_8023ad.c @@ -1387,11 +1387,12 @@ rte_eth_bond_8023ad_agg_selection_set(uint16_t port_id, struct bond_dev_private *internals; struct mode8023ad_private *mode4; + if (valid_bonded_port_id(port_id) != 0) + return -EINVAL; + bond_dev = &rte_eth_devices[port_id]; internals = bond_dev->data->dev_private; - if (valid_bonded_port_id(port_id) != 0) - return -EINVAL; if (internals->mode != 4) return -EINVAL; @@ -1408,11 +1409,12 @@ int rte_eth_bond_8023ad_agg_selection_get(uint16_t port_id) struct bond_dev_private *internals; struct mode8023ad_private *mode4; + if (valid_bonded_port_id(port_id) != 0) + return -EINVAL; + bond_dev = &rte_eth_devices[port_id]; internals = bond_dev->data->dev_private; - if (valid_bonded_port_id(port_id) != 0) - return -EINVAL; if (internals->mode != 4) return -EINVAL; mode4 = &internals->mode4; @@ -1665,9 +1667,14 @@ int rte_eth_bond_8023ad_dedicated_queues_enable(uint16_t port) { int retval = 0; - struct rte_eth_dev *dev = &rte_eth_devices[port]; - struct bond_dev_private *internals = (struct bond_dev_private *) - dev->data->dev_private; + struct rte_eth_dev *dev; + struct bond_dev_private *internals; + + if (valid_bonded_port_id(port) != 0) + return -EINVAL; + + dev = &rte_eth_devices[port]; + internals = dev->data->dev_private; if (check_for_bonded_ethdev(dev) != 0) return -1; @@ -1689,9 +1696,14 @@ int rte_eth_bond_8023ad_dedicated_queues_disable(uint16_t port) { int retval = 0; - struct rte_eth_dev *dev = &rte_eth_devices[port]; - struct bond_dev_private *internals = (struct bond_dev_private *) - dev->data->dev_private; + struct rte_eth_dev *dev; + struct bond_dev_private *internals; + + if (valid_bonded_port_id(port) != 0) + return -EINVAL; + + dev = &rte_eth_devices[port]; + internals = dev->data->dev_private; if (check_for_bonded_ethdev(dev) != 0) return -1; -- 2.20.1
