2021-04-08Bluetooth: Allow Microsoft extension to indicate curve validationMarcel Holtmann

2021-01-25Bluetooth: advmon offload MSFT handle filter enablementArchie Pusaka
Implements the feature to disable/enable the filter used for advertising monitor on MSFT controller, effectively have the same effect as "remove all monitors" and "add all previously removed monitors". This feature would be needed when suspending, where we would not want to get packets from anything outside the allowlist. Note that the integration with the suspending part is not included in this patch.

2021-01-25Bluetooth: advmon offload MSFT add monitorArchie Pusaka
Enables advertising monitor offloading to the controller, if MSFT extension is supported. The kernel won't adjust the monitor parameters to match what the controller supports - that is the user space's responsibility. This patch only manages the addition of monitors. Monitor removal is going to be handled by another patch.

2020-10-29Bluetooth: Replace zero-length array with flexible-array memberGustavo A. R. Silva
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”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

Micrsoft defined a set for HCI vendor extensions. Check the following link for details: https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/microsoft-defined-bluetooth-hci-commands-and-events This provides the basic framework to enable the extension and read its supported features. Drivers still have to declare support for this extension before it can be utilized by the host stack.
