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".

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. Signed-off-by:

There is a conflict between MediaTek wmt event and msft vendor extension logic in the core layer since 145373cb ("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.

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members" for these cases. The older style of one-element or zero-length arrays should no longer be used.

Simon Horman says: ==================== Add AF_XDP zero-copy support for NFP Niklas Söderlund says: This series adds AF_XDP zero-copy support for the NFP driver. The series is based on previous work done by Jakub Kicinski. Patch 1/5 and 2/5 prepares the driver for AF_XDP support by refactoring functions that will act differently once AF_XDP is active or not making the driver easier to read and by preparing some functions to be reused outside the local file scope. Patch 3/5 and 4/5 prepares the driver for dealing the UMEM while finally patch 5/5 adds AF_XDP support. Based on work by Jakub Kicinski. ==================== Signed-off-by: -

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.
