2013-10-19Bluetooth: Expose debugfs settings for LE connection intervalMarcel Holtmann
For testing purposes expose the default LE connection interval values via debugfs. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Add support for setting SSP debug modeMarcel Holtmann
Enabling and disabling SSP debug mode is useful for development. This adds a debugfs entry that allows to configure the SSP debug mode. On purpose this has been implemented as debugfs entry and not a public API since it is really only useful during testing and development.

2013-10-19Bluetooth: Remove interval parameter from HCI connectionMarcel Holtmann
The conn->interval parameter of HCI connections is not used at all and so just remove it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Add LE features to debugfs if availableMarcel Holtmann
For LE capable controllers at the special LE features page to the debugfs list with all the other features pages. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Expose setting if debug keys are used or notMarcel Holtmann
The system can be figured to accept and use debug keys. Expose this value in debugfs for debugging purposes. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Expose debugfs entry read/write own address typeMarcel Holtmann
For some testing it is important to know the current own addres type, but also be able to change it. The change is lost over powery cycles and only intended for debugging. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Select the own address type during initial setup phaseMarcel Holtmann
The own address type is based on the fact if the controller has a public address or not. This means that this detail can be just configured once during setup phase. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Expose current list of long term keys via debugfsMarcel Holtmann
For debugging purposes expose the current list of long term keys via debugfs. This file is read-only and limited to root access. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Expose white list size information in debugfsMarcel Holtmann
Knowing the white list size information is important for debugging. So export it via debugfs. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Remove bus attribute in favor of hierarchyMarcel Holtmann
The bus information are exposed in the actual hierarchy and should not be exposed as attribute. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Expose current list of link keys via debugfsMarcel Holtmann
For debugging purposes expose the current list of link keys via debugfs. This file is read-only and limited to root access. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Move export of class of device information into hci_core.cMarcel Holtmann
The class of device debugfs information should be directly exported from hci_core.c and so move them over there. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Store local version information only during setup phaseMarcel Holtmann
The local version information from the controller can not change since they are static. So store them only once during setup phase and not bother overwriting them every time this command gets executed. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Move manufacturer, hci_ver and hci_rev into hci_core.cMarcel Holtmann
Move the debugfs entries for manufacturer, hci_ver and hci_rev into hci_core.c and use the new helpers for static entries that will not change at runtime. Once passed the setup procedure, they will stay fixed. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Remove debug entry for connection featuresMarcel Holtmann
The debug entry for connection features is incomplete and also does not work with AMP controllers and physical links. So just remove it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Add workaround for buggy max_page features page valueMarcel Holtmann
Some controllers list the max_page value from the extended features response as 0 when SSP has not yet been enabled. To workaround this issue, force the max_page value to 1 when SSP support has been detected. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-19Bluetooth: Move HCI device features into hci_core.cMarcel Holtmann
Move the handling of HCI device features debugfs into hci_core.c and also extend it with handling of multiple feature pages. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Block ATT connection on LE when device is blockedMarcel Holtmann
When the remote LE device is blocked, then do not create a L2CAP channel for it. Without a channel, all packets for that connection will be dropped. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Use hcon directly instead of conn->hcon where possibleMarcel Holtmann
When the HCI connection hcon is already dereferenced, then use hcon directly instead of conn->hcon. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Use BDADDR_BREDR type for old blacklist ioctl interfaceMarcel Holtmann
The old blacklist ioctl interface was only able to operate on BR/EDR addresses. So use the BDADDR_BREDR address type definition instead of an open coded magic 0 value. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Fix ATT socket backwards compatibility with user spaceJohan Hedberg
Old user space versions bind the Attribute Protocol socket to BDADDR_BREDR when they should be using BDADDR_LE_PUBLIC or BDADDR_LE_RANDOM. The kernel recently introduced stricter checks on the socket parameters but we need to punch this hole for old user space versions to keep them working. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-18Bluetooth: Move idle_timeout and sniff_{min,max}_interval to hci_core.cMarcel Holtmann
Move the debugfs configuration directly into hci_core.c and only expose it when the controller actually support BR/EDR sniff power saving mode. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Include address type in blacklist debugfs dataMarcel Holtmann
The address type is important for the blacklist entries. So include it at well. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Move device_add handling into hci_register_devMarcel Holtmann
The device_add handling can be done directly in hci_register_dev and device_remove within hci_unregister_dev. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Create root debugfs directory during module initMarcel Holtmann
Create the root Bluetooth debugfs directory during module init and remove it on module exit. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Create HCI device debugfs directory in hci_register_devMarcel Holtmann
Create the debugfs directory for each HCI device directly in hci_register_dev function and remove it during hci_unregister_dev. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Use IS_ERR_OR_NULL for checking bt_debugfsMarcel Holtmann
Make sure to use IS_ERR_OR_NULL for checking the existing of the root debugfs dentry bt_debugfs. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Move uuids debugfs entry creation into hci_core.cMarcel Holtmann
The uuids debugfs should only be created together with the other entries after the setup procedure has been finished. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Move blacklist debugfs entry creation into hci_core.cMarcel Holtmann
The blacklist debugfs should only be created together with the other entries after the setup procedure has been finished. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-18Bluetooth: Add address type to device blacklist tableMarcel Holtmann
The device blacklist is not taking care of the address type. Actually store the address type in the list entries and also use them when looking up addresses in the table. This is actually a serious bug. When adding a LE public address to the blacklist, then it would be blocking a device on BR/EDR. And this is not the expected behavior. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-17Bluetooth: Expose current voice setting in debugfsMarcel Holtmann
For easier debugging of the current voice setting, expose the value in debugfs if the controller is BR/EDR capable. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-17Bluetooth: Expose static address value for LE capable controllersMarcel Holtmann
For LE capable controllers, the static address can be configured. For debugging purposes expose the value in debugfs. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-17Bluetooth: Expose auto_accept_delay debugfs only when SSP is supportedMarcel Holtmann
The auto_accept_delay debugfs entry is only valid for BR/EDR capable controllers that also support SSP. If SSP is not available or it is a LE-only single mode controller this value has no affect and so do not expose it. Since the value can be actually changed, switch the permissions to 0644 to clearly indicate that the value is indeed writeable. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-16Bluetooth: Expose inquiry_cache debugfs only on BR/EDR controllersMarcel Holtmann
The inquiry_cache debugfs entry is only valid for BR/EDR capable controllers. In case of single mode LE-only controllers that entry is not valid. Move the creating of the debugfs entries to the end of controller init and only create the inquiry_cache entry if BR/EDR is actually supported. At the same time this avoids creating any debugfs entries for AMP controllers since none of the entries are valid there.

2013-10-16Bluetooth: Socket address parameter for CID is in little endianMarcel Holtmann
The L2CAP socket parameter for CID are actually provided in little endian. So convert our constants into little endian before comparing them. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-16Bluetooth: Convert idle timer to use delayed workJohan Hedberg
There is no need to use a timer since the entire Bluetooth subsystem runs using workqueues these days. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-16Bluetooth: Convert auto accept timer to use delayed workJohan Hedberg
Since the entire Bluetooth subsystem runs in workqueues these days there is no need to use a timer for deferring work. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-16Bluetooth: Reintroduce socket restrictions for LE socketsJohan Hedberg
Right now we do not allow user space to use connection oriented channels on LE, and the only CID that can be used is the Attribute Protocol one. These restrictions went away together with the recent refactoring of the L2CAP code, but this patch puts them back to their appropriate places. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-16Bluetooth: Fix updating the right variable in update_scan_rsp_data()Johan Hedberg
This function should be operating on scan_rsp_data_len and scan_rsp_data and not the advertising data variables. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-16Bluetooth: Remove enable_hs declarationMarcel Holtmann
This seems to be a left-over. The module parameter enable_hs has been removed, but its extern declaration is still present. It is not needed anymore, so just remove it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-16Bluetooth: Ignore SMP data on non-LE linksJohan Hedberg
The SMP CID is only defined for LE transports. Instead of returning an error from smp_sig_channel() in this case (which would cause a disconnection) just return 0 to ignore the data, which is consistent with the behavior for other unknown CIDs. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-16Bluetooth: Ignore A2MP data on non-BR/EDR linksJohan Hedberg
The A2MP CID is only valid for BR/EDR transports. We should ignore A2MP data on non-BR/EDR links and refuse to create an amp_mgr object. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-16Bluetooth: Remove useless l2cap_err_to_reason functionJohan Hedberg
Now that the only reason code this function can return is L2CAP_REJ_NOT_UNDERSTOOD we can just do the necessary assignment without needing a separate function at all. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-16Bluetooth: Remove unused command reject mapping for EMSGSIZEJohan Hedberg
There is no command handler that would return an EMSGSIZE error, so just remove this mapping from the l2cap_err_to_reason function. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-16Bluetooth: Fix L2CAP "Command Reject: Invalid CID" responseJohan Hedberg
When the reason code in the L2CAP command reject is "invalid CID" there should be four additional bytes of data in the PDU, namely the source and destination CIDs (which should be zero if one or both are not applicable). This patch fixes all occurrences of such errors to return the right kind of PDU. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2013-10-16Bluetooth: Remove duplicate definitions for advertising event typesMarcel Holtmann
The constants for advertising event types have been defined twice. So remove one copy of it. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-16Bluetooth: Rename update_ad into update_adv_dataMarcel Holtmann
Since there is update_scan_rsp_data, it is also better to use the clear name update_adv_data instead of update_ad. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-16Bluetooth: Store device name in scan response dataMarcel Holtmann
The scan response data is a better place to store the device name since it has more space available and is also enforcing privacy. When the controller is advertising, the connectable setting decides if ADV_IND or ADV_NONCONN_IND is used. In case of ADV_IND, the remote side is allowed to request the scan response data. Same as with BR/EDR where either EIR is used or a remote name request. In non-connectable mode, the device name is not available since it is not allowed to request scan response data. Same as in BR/EDR where the device is non-discoverable and no name requests are answered. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-16Bluetooth: Set the scan response data when neededMarcel Holtmann
On controller power on and when enabling LE functionality, make sure that also the scan response data is correctly set. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-16Bluetooth: Store scan response data in HCI deviceMarcel Holtmann
The scan response data needs to be stored in HCI device and so add a buffer for it and also ensure to clear it when resetting the controller. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
