2019-07-03net/mlx5: Introduce and use mlx5_eswitch_get_total_vports()Parav Pandit1-1/+1
Instead MLX5_TOTAL_VPORTS, use mlx5_eswitch_get_total_vports(). mlx5_eswitch_get_total_vports() in subsequent patch accounts for SF vports as well. Expanding MLX5_TOTAL_VPORTS macro would require exposing SF internals to more generic vport.h header file. Such exposure is not desired. Hence a mlx5_eswitch_get_total_vports() is introduced. Given that mlx5_eswitch_get_total_vports() API wants to work on const mlx5_core_dev*, change its helper functions also to accept const *dev.

2019-07-03IB/mlx5: Fixed reporting counters on 2nd port for Dual port RoCEParav Pandit1-24/+36
Currently during dual port IB device registration in below code flow, ib_register_device() ib_device_register_sysfs() ib_setup_port_attrs() add_port() get_counter_table() get_perf_mad() process_mad() mlx5_ib_process_mad() mlx5_ib_process_mad() fails on 2nd port when both the ports are not fully setup at the device level (because 2nd port is unaffiliated). As a result, get_perf_mad() registers different PMA counter group for 1st and 2nd port, namely pma_counter_ext and pma_counter. However both ports have the same capability and counter offsets. Due to this when counters are read by the user via sysfs in below code flow, counters are queried from wrong location from the device mainly from PPCNT instead of VPORT counters. show_pma_counter() get_perf_mad() process_mad() mlx5_ib_process_mad() process_pma_cmd() This shows all zero counters for 2nd port. To overcome this, process_pma_cmd() is invoked, and when unaffiliated port is not yet setup during device registration phase, make the query on the first port. while at it, only process_pma_cmd() needs to work on the native port number and underlying mdev, so shift the get, put calls to where its needed inside process_pma_cmd().

IBTA 11.2.2 notes no such return value or error case: Output Modifiers: - Verb results: - Operation completed successfully. - Invalid HCA handle. - Invalid address handle.

The Affected QP shall be moved to the error state and affiliated asynchronous errors generated as described in 11.6.3.1 Affiliated Asynchronous Events on page 678. The current WQE and any subsequent WQEs are left in an unknown state. C11-37: The CI shall generate a CQ Error when a CQ overrun is detected. This condition will result in an Affiliated Asynchronous Error for any associated Work Queues when they attempt to use that CQ. Completions can no longer be added to the CQ. It is not guaranteed that completions present in the CQ at the time the error occurred can be retrieved. Possible causes include a CQ overrun or a CQ protection error.

2019-06-25RDMA/netlink: Audit policy settings for netlink attributesDoug Ledford1-13/+12
For all string attributes for which we don't currently accept the element as input, we only use it as output, set the string length to RDMA_NLDEV_ATTR_EMPTY_STRING which is defined as 1. That way we will only accept a null string for that element. This will prevent someone from writing a new input routine that uses the element without also updating the policy to have a valid value. Also while there, make sure the existing entries that are valid have the correct policy, if not, correct the policy. Remove unnecessary checks for nla_strlcpy() overflow once the policy has been set correctly. Signed-off-by: Doug Ledford <dledford@redhat.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
