Sender of the block device command gets cmd complete and other mgmt sockets get the event. Event is also sent to mgmt sockets when blocking is done with ioctl, e.g when blocking a device with hciconfig. This makes it possible for bluetoothd to track status of blocked devices when a third party block or unblocks a device. Event sending is handled in mgmt_device_blocked function which gets called from hci_blacklist_add in hci_core.c. A pending command is added in mgmt_block_device, so that it can found when sending the event - the event is not sent to the socket from which the pending command came. Locks were moved out from hci_core.c to hci_sock.c and mgmt.c, because locking is needed also for mgmt_pending_add in mgmt.c. Signed-off-by: Antti Julku Signed-off-by: Gustavo F.
