Lukasz Majewski d183f297cb hsr: Simplify code for announcing HSR nodes timer setup ... [ Upstream commit 4893b8b3ef ] Up till now the code to start HSR announce timer, which triggers sending supervisory frames, was assuming that hsr_netdev_notify() would be called at least twice for hsrX interface. This was required to have different values for old and current values of network device's operstate. This is problematic for a case where hsrX interface is already in the operational state when hsr_netdev_notify() is called, so timer is not configured to trigger and as a result the hsrX is not sending supervisory frames to HSR ring. This error has been discovered when hsr_ping.sh script was run. To be more specific - for the hsr1 and hsr2 the hsr_netdev_notify() was called at least twice with different IF_OPER_{LOWERDOWN|DOWN|UP} states assigned in hsr_check_carrier_and_operstate(hsr). As a result there was no issue with sending supervisory frames. However, with hsr3, the notify function was called only once with operstate set to IF_OPER_UP and timer responsible for triggering supervisory frames was not fired. The solution is to use netif_oper_up() and netif_running() helper functions to assess if network hsrX device is up. Only then, when the timer is not already pending, it is started. Otherwise it is deactivated.
