[dpdk-dev] [PATCH v3 1/2] ethdev: fix data room size verification in Rx queue setup

[Wei Hu (Xavier)]

In the rte_eth_rx_queue_setup API function, the local variable named
mbp_buf_size, which is the data room size of the input parameter mp,
is checked to guarantee that each memory chunck used for net device
in the mbuf is bigger than the min_rx_bufsize. But if mbp_buf_size is
less than RTE_PKTMBUF_HEADROOM, the value of the following  statement
will be a large number since the mbp_buf_size is a unsigned value.
    mbp_buf_size - RTE_PKTMBUF_HEADROOM
As a result, it will cause a segment fault in this situation.

This patch fixes it by modify the check condition to guarantee that the
local varibale named mbp_buf_size is bigger than RTE_PKTMBUF_HEADROOM.

[dpdk-dev] [PATCH v3 2/2] ethdev: fix VLAN offloads set if no relative capabilities

[Wei Hu (Xavier)]

Currently, there is a potential problem that calling the API function
rte_eth_dev_set_vlan_offload to start VLAN hardware offloads which the
driver does not support. If the PMD driver does not support certain VLAN
hardware offloads and does not check for it, the hardware setting will
not change, but the VLAN offloads in dev->data->dev_conf.rxmode.offloads
will be turned on.

It is supposed to check the hardware capabilities to decide whether the
relative callback needs to be called just like the behavior in the API
function named rte_eth_dev_configure. And it is also needed to cleanup
duplicated checks which are done in some PMDs. Also, note that it is
behaviour change for some PMDs which simply ignore (with error/warning log
message) unsupported VLAN offloads, but now it will fail.

The changes looks good but the label "next_mask" and its usage above 
should also be deleted/replaced.

OK, I will delete "next_mask" and modify the function that when the offload
is not supported the function fail as below,
what do you think of it? Looking forward to your comment.

static int
dpaa2_vlan_offload_set(struct rte_eth_dev *dev, int mask)
{
     struct dpaa2_dev_priv *priv = dev->data->dev_private;
     struct fsl_mc_io *dpni = dev->process_private;
     int ret = 0;

     PMD_INIT_FUNC_TRACE();

     if (mask & ETH_VLAN_FILTER_MASK) {
         /* VLAN Filter not avaialble */
         if (!priv->max_vlan_filters) {
             DPAA2_PMD_INFO("VLAN filter not available");
             return -ENOTSUP;
         }

         if (dev->data->dev_conf.rxmode.offloads &
             DEV_RX_OFFLOAD_VLAN_FILTER)
             ret = dpni_enable_vlan_filter(dpni, CMD_PRI_LOW,
                               priv->token, true);
         else
             ret = dpni_enable_vlan_filter(dpni, CMD_PRI_LOW,
                               priv->token, false);
         if (ret < 0)
             DPAA2_PMD_INFO("Unable to set vlan filter = %d", ret);
     }

     return ret;
