The private port_list array has a list of pointers to mvpp2_port instances. This list is allocated given the number of ports enabled in the device tree, but the pointers are set using the port-id property. If on a single port is enabled, the port_list array will be of size 1, but when registering the port, if its id is not 0 the driver will crash. Other crashes were encountered in various situations. This fixes the issue by using an index not equal to the value of the port-id property.

2017-09-28net/mlx5e: Fix calculated checksum offloads countersGal Pressman4-6/+13
Instead of calculating the offloads counters, count them explicitly. The calculations done for these counters would result in bugs in some cases, for example: When running TCP traffic over a VXLAN tunnel with TSO enabled the following counters would increase: tx_csum_partial: 1,333,284 tx_csum_partial_inner: 29,286 tx4_csum_partial_inner: 384 tx7_csum_partial_inner: 8 tx9_csum_partial_inner: 34 tx10_csum_partial_inner: 26,807 tx11_csum_partial_inner: 287 tx12_csum_partial_inner: 27 tx16_csum_partial_inner: 6 tx25_csum_partial_inner: 1,733 Seems like tx_csum_partial increased out of nowhere. The issue is in the following calculation in mlx5e_update_sw_counters: s->tx_csum_partial = s->tx_packets - tx_offload_none - s->tx_csum_partial_inner; While tx_packets increases by the number of GSO segments for each SKB, tx_csum_partial_inner will only increase by one, resulting in wrong tx_csum_partial counter.

2017-09-28net/mlx5e: Check encap entry state when offloading tunneled flowsVlad Buslov1-0/+3
Encap entries cached by the driver could be invalidated due to tunnel destination neighbour state changes. When attempting to offload a flow that uses a cached encap entry, we must check the entry validity and defer the offloading if the entry exists but not valid. When EAGAIN is returned, the flow offloading to hardware takes place by the neigh update code when the tunnel destination neighbour becomes connected.

2017-09-22bnxt_re: Fix memory leak in FRMR pathSelvin Xavier1-1/+1
This patch fixes a memory leak issue when alloc_mr is used. mr->pages and mr->npages are used only in alloc_mr path. mr->pages is allocated when alloc_mr is called or in the case of FRMR, while creating the MR. mr->npages is updated only when the MR created is used i.e. after invoking map_mr_sg verb, before data transfer. In the dereg_mr path, if mr->npages is 0, driver ends up not freeing the memory created. Removing the npages check from the dereg_mr path for kernel consumers.

2017-09-22bnxt_re: Remove RTNL lock dependency in bnxt_re_query_portSomnath Kotur3-8/+9
When there is a NETDEV_UNREGISTER event, bnxt_re driver calls ib_unregister_device() (RTNL lock held). ib_unregister_device attempts to flush a worker queue scheduled by ib_core and that queue might have a pending ib_query_port(). ib_query_port in turn calls bnxt_re_query_port(), which while querying the link speed using ib_get_eth_speed(), tries to acquire the rtnl_lock() which was already held by NETDEV_UNREGISTER. Fixing the issue by removing the link speed query from bnxt_re_query_port() Now the speed is queried post a successful ib_register_device or whenever there is a NETDEV_CHANGE event.

2017-09-22bnxt_re: Fix race between the netdev register and unregister eventsSomnath Kotur2-5/+15
Upon receipt of the NETDEV_REGISTER event from the netdev notifier chain, the IB stack registration is spawned off to a workqueue since that also requires an rtnl lock. There could be 2 kinds of races between the NETDEV_REGISTER and the NETDEV_UNREGISTER event handling. a)The NETDEV_UNREGISTER event is received in rapid succession after the NETDEV_REGISTER event even before the work queue got a chance to run. b)The NETDEV_UNREGISTER event is received while the workqueue that handles registration with the IB stack is still in progress. Handle both the races with a bit flag that is set just before the work item is queued and cleared in the workqueue after the event is handled just before the workqueue item is freed. While adding the new flag, it was noted that the flags are all used in *_bit() operations which expect a bit number and not a literal constant with a bit set. So change the numbers to be bit numbers.

2017-09-22bnxt_re: Stop issuing further cmds to FW once a cmd times outSomnath Kotur2-1/+6
Once a cmd to FW times out(after 20s) it is reasonable to assume the FW or atleast the control path is dead. No point issuing further cmds to the FW as each subsequent cmd with another 20s timeout will cascade resulting in unnecessary traces and/or NMI Lockups.
