2022-11-16net: microchip: sparx5: Fix potential null-ptr-deref in sparx_stats_init() ↵Shang XiaoJing
and sparx5_start() sparx_stats_init() calls create_singlethread_workqueue() and not checked the ret value, which may return NULL. And a null-ptr-deref may happen: sparx_stats_init() create_singlethread_workqueue() # failed, sparx5->stats_queue is NULL queue_delayed_work() queue_delayed_work_on() __queue_delayed_work() # warning here, but continue __queue_work() # access wq->flags, null-ptr-deref Check the ret value and return -ENOMEM if it is NULL. So as sparx5_start().

Implement the function get_ts_info in ethtool_ops which is needed to get the HW capabilities for timestamping. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-02-03net: sparx5: Fix get_stat64 crash in tcpdumpSteen Hegelund
This problem was found with Sparx5 when the tcpdump tool requests the do_get_stats64 (sparx5_get_stats64) statistic. The portstats pointer was incorrectly incremented when fetching priority based statistics.

2021-06-24net: sparx5: add ethtool configuration and statistics supportSteen Hegelund
This adds statistic counters for the network interfaces provided by the driver. It also adds CPU port counters (which are not exposed by ethtool). This also adds support for configuring the network interface parameters via ethtool: speed, duplex, aneg etc. Signed-off-by: Steen Hegelund <steen.hegelund@microchip.com> Signed-off-by: Bjarni Jonasson <bjarni.jonasson@microchip.com> Signed-off-by: Lars Povlsen <lars.povlsen@microchip.com> Signed-off-by: David S.
