2022-03-04Bluetooth: move adv_instance_cnt read within the device lockNiels Dossche1-1/+3
The field adv_instance_cnt is always accessed within a device lock, except in the function add_advertising. A concurrent remove of an advertisement with adding another one could result in the if check "if a new instance was actually added" to not trigger, resulting in not triggering the "advertising added event".

2022-03-04Bluetooth: hci_event: Add missing locking on hdev in hci_le_ext_adv_term_evtNiels Dossche1-7/+12
Both hci_find_adv_instance and hci_remove_adv_instance have a comment above their function definition saying that these two functions require the caller to hold the hdev->lock lock. However, hci_le_ext_adv_term_evt does not acquire that lock and neither does its caller hci_le_meta_evt (hci_le_meta_evt calls hci_le_ext_adv_term_evt via an indirect function call because of the lookup in hci_le_ev_table). The other event handlers all acquire and release the hdev->lock and they follow the rule that hci_find_adv_instance and hci_remove_adv_instance must be called while holding the hdev->lock lock. The solution is to make sure hci_le_ext_adv_term_evt also acquires and releases the hdev->lock lock. The check on ev->status which logs a warning and does an early return is not covered by the lock because other functions also access ev->status without holding the lock.

2022-03-04Bluetooth: mediatek: fix the conflict between mtk and msft vendor eventSean Wang3-16/+2
There is a conflict between MediaTek wmt event and msft vendor extension logic in the core layer since 145373cb1b1f ("Bluetooth: Add framework for Microsoft vendor extension") was introduced because we changed the type of mediatek wmt event to the type of msft vendor event in the driver. But the purpose we reported mediatek event to the core layer is for the diagnostic purpose with that we are able to see the full packet trace via monitoring socket with btmon. Thus, it is harmless we keep the original type of mediatek vendor event here to avoid breaking the msft extension function especially they can be supported by Mediatek chipset like MT7921 , MT7922 devices and future devices.

2022-03-04nfp: xsk: add AF_XDP zero-copy Rx and Tx supportNiklas Söderlund6-28/+756
This patch adds zero-copy Rx and Tx support for AF_XDP sockets. It do so by adding a separate NAPI poll function that is attached to a each channel when the XSK socket is attached with XDP_SETUP_XSK_POOL, and restored when the XSK socket is terminated, this is done per channel. Support for XDP_TX is implemented and the XDP buffer can safely be moved from the Rx to the Tx queue and correctly freed and returned to the XSK pool once it's transmitted. Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS will allocate a new buffer and copy the zero-copy frame prior passing it to the kernel stack.

Add support for ptp interrupt. This interrupt is used when using 2-step timestamping. For each timestamp that is added in a queue, an interrupt is generated. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-03-04dt-bindings: net: sparx5: Extend with the ptp interruptHoratiu Vultur1-0/+2

2022-03-04net: sparx5: Move ifh from port to local variableHoratiu Vultur3-5/+8
Currently the ifh is not changed, it is fixed for each frame for each port that is sent out. Move this on the stack because this ifh needs to be change based on the frames that are send out. This is needed for PTP frames. Signed-off-by: Horatiu Vultur <horatiu.vultur@microchip.com> Signed-off-by: David S. Miller <davem@davemloft.net>

LAN937x T1 switch is based on LAN87xx Phy, so reusing the init script of the LAN87xx. There is a workaround in accessing the DSP bank register for LAN937x Phy. Whenever there is a bank switch to DSP registers, then we need a one dummy read access before proceeding to the actual register access.
