Update hdev workqueue API usage to use the new interface, this new interface also allow us to mark this workqueue as WQ_HIGHPRI, so now rx and tx work gets higher priority when running. Acked-by:

hdev->workqueue will be only for for rx/tx/cmd processing, all other small works should go to the system workqueue for now. Acked-by:

This list has much more reads than writes, so RCU makes senses here, also it avoid deadlock against the socket lock. Acked-by:

This move some checking code that was in l2cap_sock_connect() to l2cap_chan_connect(). Thus we can invert the lock calls, i.e., call lock_sock() before hci_dev_lock() to avoid a deadlock scenario. Acked-by:

It's pointless, we aren't protecting anything since btusb_notify() schedules a work to run, then all it operation happens without protection. If protection is really needed here, we will fix it further. Acked-by:

Handling hci_conn_hash with RCU make us avoid some locking and disable tasklets. Acked-by:
-
Gustavo F. Padovan authored
Instead of using tasklet_disable() to prevent acess to the channel use, we can use RCU and improve the performance of our code. Acked-by:

Now we can sleep in any path inside Bluetooth core, so mutex can make sense here. Acked-by:

We run everything in the same lock now. The backlog queue is useless now Acked-by:

We now run everything in process context, so the mutex lock is the best option. But in some places we still need the bh_lock_sock() Acked-by:

L2CAP timers also need to run in process context. As the works in l2cap are small we are using the system worqueue. Acked-by:

It doesn't really touch any sensitive information about hdev. So no need to lock here. Acked-by:

As HCI rx path is now done in process context it makes sense to do all the timer in process context as well. Acked-by:

Bluetooth rx task runs now in a workqueue, so it a good approach run any timer that share locking with process context code also in a workqueue. Acked-by:

Gustavo F. Padovan authored
Now we run everything in HCI in process context, so it's a better idea use mutex instead spin_lock. The macro remains hci_dev_lock() (and I got rid of hci_dev_lock_bh()), of course. Acked-by:

Run recv process in workqueue helps a lot with our processing as the recv path will also be in the process context, i.e., now all our tx and rx are in process context. Signed-off-by:

This patch adds the dev_flags field to struct hci_dev. This new flags variable should be used to define flags related to BR/EDR and/or LE controller itself. It should be used to define flags which represents states from the controller. The dev_flags is cleared in case the controller sends a Reset Command Complete Event to the host. Also, this patch adds the HCI_LE_SCAN flag which was created to track if the controller is performing LE scan or not. The flag is set/cleared when the controller starts/stops scanning. This is an initial effort to stop using hdev->flags to define internal flags since it is exported to userspace by an ioctl. Signed-off-by:
