We'll soon have specific clear functions for clearing enabled or disabled entries, so rename the function that removes everything to clear_all(). Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

This patch fixes the following sparse warning caused by a missing declaration in the header file: drivers/bluetooth/btmrvl_main.c:218:5: warning: symbol 'btmrvl_pscan_window_reporting' was not declared. Should it be static? Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

The Broadcom BCM20702A0 USB controllers might come with the default address 00:20:70:02:A0:00 when booting up. If this happens, then warn about such address being used. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

Some Intel Bluetooth controllers come with a default address. If this address is found, print an error to warn the user about it. The controller is fully operational, but the danger of duplicate Bluetooth addresses might causes issues. At least with a clear error it becomes easier to debug these cases.

When allocating a new controller structure, then default to the internal use value 0xffff first. Default to 0x0000 is a bad idea since that is the manufacturer identifier of Ericsson Technology Licensing.

Unlike BR/EDR we cannot reject LE connections of blocked devices but have to do it as soon as we get a LE Connection Complete event. The patch adds a blacklist check to the hci_le_conn_complete_evt function and drops all connections for blocked devices.

The ATT channel isn't the only one that we should ensure doesn't receive data from blocked devices. SMP is another, and in general we don't want data packets going to any of the various handlers. Therefore, add a single check to the l2cap_recv_frame function. The patch fixes at the same time the use of a correct address type. The blacklist stores the values with the user space facing triple type wheras hci_conn->dst_type uses the HCI address type (0x00 or 0x01).

This patch introduces a new Mgmt event called "New Connection Parameter". This event indicates to userspace the connection parameters values the remote device requested. The user may store these values and load them into kernel. This way, next time a connection is established to that device, the kernel will use those parameters values instead of the default ones. This event is sent when the remote device requests new connection parameters through connection parameter update procedure. This event is not sent for slave connections.

The Bluetooth 4.1 introduces a new LE meta event called "LE Remote Connection Parameter Request" event. In order to the controller sends this event to host, we should enable it during controller initialization.

During init2 phase, the LE local features have not be read yet so we aren't able to rely on hdev->le_features to determine if the controller supports the Connection Parameters Request Procedure. For that reason, this patch moves LE event mask setting from init2 into init3 initialization phase. The hdev->le_features mask will be checked by the next patch in order to know if "LE Remote Connection Parameter Request Event" should be enabled.

This patch adds support for LE Connection Parameters Request Link Layer control procedure introduced in Core spec 4.1. This procedure allows a Peripheral or Central to update the Link Layer connection parameters of an established connection. Regarding the acceptance of connection parameters, the LL procedure follows the same approach of L2CAP procedure (see l2cap_conn_param_ update_req function). We accept any connection parameters values as long as they are within the valid range. Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

After BT_CMD_HOST_SLEEP_ENABLE command finishes, driver should wait until getting BT_EVENT_HOST_SLEEP_ENABLE event to complete suspend procedure. Without this patch the suspend handler would return success earlier. By the time when the BT_EVENT_HOST_SLEEP_ENABLE event comes in the controller driver could have already turned off the bus clock. This causes kernel crash or system reboot eventually.

For the Block/Unblock Device mgmt commands we should only emit the Blocked/Unblocked events on any socket except for the one which received the command. The code was previously incorrectly trying to look up a non-existent pending command and thereby ending up not skipping the command socket for the event. We can simplify the code a lot by simply sending the event directly from the command handler functions. We have the reference to the command socket available there which makes it easy to pass to the mgmt_event function for skipping. The only notable side-effect of this is that the old blacklisting ioctl's no-longer cause mgmt events to be emitted, however as user space versions using these ioctl's are not mgmt-aware this is acceptable.

The background scanning normally gets enabled during power on by adding devices to the pending connection list. However devices might be already on that list and the list of devices is empty, then it is better to trigger the background manually.

When a new controller is initialized, but not powered from userspace at the moment, the HCI_AUTO_OFF flag is still set. During this period, userspace might program device for auto-connection, but never power on the controller. In this case do not try to start background scanning and leave it for later to be started.

If we're encrypted with the STK we should allow re-encryption with an LTK even though the achieved security level is the same.

There are certain subtle differences in behavior when we're encrypted with the STK, such as allowing re-encryption even though the security level stays the same. Because of this, add a flag to track whether we're encrypted with an STK or not. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>

If we're already encrypted with a good enough LTK we should just ignore an incoming SMP Security Request. The code was already taking care of this in the smp_conn_security function before calling smp_ltk_encrypt but failed to do the same in smp_cmd_security_req. This patch fixes the issue by moving up the smp_sufficient_security function and using it in the Security Request handler before trying to request encryption.

Providing the flags parameter directly to mgmt_device_found function makes the core simpler and more readable. With this it becomes a lot easier to add new flags in the future. This also changes hci_inquiry_cache_update to just return that flags needed for mgmt_device_found since that is its only use for the two return parameters anyway.

The connection interval parameter of hci_conn_params_set are always used with the controller defaults.

The hci_conn_params_add function provides the default allocation of connection parameters. To avoid code duplication, use that code from hci_conn_params_set to allocate or lookup parameter struct. As a benefit the connection latency and supervision timeout parameters are no longer reset to default when calling hci_conn_params_set.

When trying to pair a new Bluetooth Low Energy device, then make sure that the default connections parameters are in place before trying to establish the first connection to that device. With the connection parameters structure allocated, the slave preferred values can now easily be tracked and all future connections will use the correct values from that start decreasing connection establishment time.

In some cases it is useful to not overwrite connection parametes and instead just create default ones if they don't exist. This function does exactly that. hci_conn_params_add will allow to create new default connection parameters. hci_conn_params_set will set the values and also create new parameters if they don't exist.
