Horatiu Vultur says: ==================== net: lan966x: lan966x fixes This contains different fixes for lan966x in different areas like PTP, MAC, Switchdev and IGMP processing. ==================== Link: https://lore.kernel.org/r/20220409184143.1204786-1-horatiu.vultur@microchip.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-04-12net: lan966x: Stop processing the MAC entry is port is wrong.Horatiu Vultur1-2/+4
Currently when getting a new MAC is learn, the HW generates an interrupt. So then the SW will check the new entry and checks if it arrived on a correct port. If it didn't just generate a warning. But this could still crash the system. Therefore stop processing that entry when an issue is seen.

2022-04-12net: lan966x: Fix when a port's upper is changed.Horatiu Vultur1-2/+1
On lan966x it is not allowed to have foreign interfaces under a bridge which already contains lan966x ports. So when a port leaves the bridge it would call switchdev_bridge_port_unoffload which eventually will notify the other ports that bridge left the vlan group but that is not true because the bridge is still part of the vlan group. Therefore when a port leaves the bridge, stop generating replays because already the HW cleared after itself and the other ports don't need to do anything else.

2022-04-12net: lan966x: Fix IGMP snooping when frames have vlan tagHoratiu Vultur1-0/+6
In case an IGMP frame has a vlan tag, then the function lan966x_hw_offload couldn't figure out that is a IGMP frame. Therefore the SW thinks that the frame was already forward by the HW which is not true. Extend lan966x_hw_offload to pop the vlan tag if are any and then check for IGMP frames.

2022-04-12net: lan966x: Update lan966x_ptp_get_nominal_valueHoratiu Vultur1-4/+4
The clk_per_cfg register represents the value added to the system clock for each clock cycle. The issue is that the default value is wrong, meaning that in case the DUT was a grandmaster then everone in the network was too slow. In case there was a grandmaster, then there is no issue because the DUT will configure clk_per_cfg register based on the master frequency.

2022-04-12net: macb: Restart tx only if queue pointer is laggingTomas Melin1-0/+8
commit 4298388574da ("net: macb: restart tx after tx used bit read") added support for restarting transmission. Restarting tx does not work in case controller asserts TXUBR interrupt and TQBP is already at the end of the tx queue. In that situation, restarting tx will immediately cause assertion of another TXUBR interrupt. The driver will end up in an infinite interrupt loop which it cannot break out of. For cases where TQBP is at the end of the tx queue, instead only clear TX_USED interrupt. As more data gets pushed to the queue, transmission will resume. This issue was observed on a Xilinx Zynq-7000 based board. During stress test of the network interface, driver would get stuck on interrupt loop within seconds or minutes causing CPU to stall.

2022-04-11net/sched: taprio: Check if socket flags are validBenedikt Spranger1-1/+2
A user may set the SO_TXTIME socket option to ensure a packet is send at a given time. The taprio scheduler has to confirm, that it is allowed to send a packet at that given time, by a check against the packet time schedule. The scheduler drop the packet, if the gates are closed at the given send time. The check, if SO_TXTIME is set, may fail since sk_flags are part of an union and the union is used otherwise. This happen, if a socket is not a full socket, like a request socket for example. Add a check to verify, if the union is used for sk_flags.

2022-04-10ath9k: Fix usage of driver-private space in tx_infoToke Høiland-Jørgensen2-11/+21
The ieee80211_tx_info_clear_status() helper also clears the rate counts and the driver-private part of struct ieee80211_tx_info, so using it breaks quite a few other things. So back out of using it, and instead define a ath-internal helper that only clears the area between the status_driver_data and the rates info. Combined with moving the ath_frame_info struct to status_driver_data, this avoids clearing anything we shouldn't be, and so we can keep the existing code for handling the rate information. While fixing this I also noticed that the setting of tx_info->status.rates[tx_rateindex].count on hardware underrun errors was always immediately overridden by the normal setting of the same fields, so rearrange the code so that the underrun detection actually takes effect. The new helper could be generalised to a 'memset_between()' helper, but leave it as a driver-internal helper for now since this needs to go to stable.
