Incoming sk_buffs always have bt_cb(skb)->force_active set to 0, so it's misleading to use that value from the control block when calling hci_conn_enter_active_mode() for incoming data. The destination socket is not known in the HCI layer, so the force_active setting for each socket isn't known either. Hard-coding the force_active parameter does not change any behavior, but makes it obvious that incoming ACL data never exits sniff mode. Signed-off-by:

We do not want the service cache to be enabled indefinitely after mgmt_read_info is called. To solve this a timer is added which will automatically disable the cache if mgmt_set_dev_class isn't called within 5 seconds of calling mgmt_read_info. Signed-off-by:

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:

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:

Use queue instead of stack discipline for device list. When processing dev_list with list_for_each* devices will be prosessed in order they were added (Usually BR/EDR first and AMP later). Also output from hciconfig looks nicer :-) Signed-off-by:

This patch moves the pending management command list (previously global to mgmt.c) into struct hci_dev. This makes it possible to do proper locking when accessing it (through the existing hci_dev locks) and thereby avoid race conditions. Signed-off-by:

Johan Hedberg authored
The current global pending command list in mgmt.c is racy. Possibly the simplest way to fix it is to have per-hci dev lists instead of a global one (all commands that need a pending struct are hci_dev specific). This way the list can be protected using the already existing per-hci dev lock. To enable this refactoring the first thing that needs to be done is to ensure that the mgmt functions have access to the hci_dev struct (instead of just the dev id). Signed-off-by:

This patch adds a function to hci_core to cancel an ongoing inquiry. According to the Bluetooth spec, the inquiry cancel command should only be issued after the inquiry command has been issued, a command status event has been received for the inquiry command, and before the inquiry complete event occurs. As HCI_INQUIRY flag is only set just after an inquiry command status event occurs and it is cleared just after an inquiry complete event occurs, the inquiry cancel command should be issued only if HCI_INQUIRY flag is set. Additionally, cancel inquiry related code from stop_discovery() were replaced by a hci_cancel_inquiry() call. Signed-off-by:

To avoid starvation the priority is recalculated so that the starving channels are promoted to HCI_PRIO_MAX - 1 (6). HCI_PRIO_MAX (7) is considered special, because it requires CAP_NET_ADMIN capability which can be used to provide more guaranties, so it is not used when promoting. Signed-off-by:

I've noticed that my CSR usb dongle was not working if it was plugged in when PC was booting. It looks like I get two HCI reset command complete events (see hcidump logs below). The root cause is reset called from off_timer. Timeout for this reset to complete is set to 250ms and my bt dongle requires more time for replying with command complete event. After that, chip seems to reply with reset command complete event for next non-reset command. Attached patch increase mentioned timeout to HCI_INIT_TIMEOUT, this value is already used for timeouting hci_reset_req in hci_dev_reset(). This might also be related to BT not working after suspend that was reported here some time ago.
