* mac80211: Remove superfluous if clauseHelmut Schaa2011-02-141-11/+1
| | | | | | | | | | ieee80211_rx_h_check returned RX_DROP_MONITOR in case the if statement in question was true but the same return value is also used directly after the if clause. Hence, we can just drop the whole if clause and as such simplify the code. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: Ensure power-level set properly for scanning.Ben Greear2011-02-092-2/+10
| | | | | | | | | | | My previous patch to optimize scanning on operating channel accidentally removed the code that would ensure power was set to maximum for scanning. This patch re-adds that functionality. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: Allow work items to use existing channel type.Ben Greear2011-02-091-3/+50
| | | | | | | | | | Narrow channel types can function within larger channel types. So, use existing channel type for work items when possible. This decreases hardware channel changes significantly when using non NO_HT channel types on the operating channel. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W.

* mac80211: Allow scanning on existing channel-type.Ben Greear2011-02-092-6/+16
| | | | | | | | | | Previous code set the channel type to NO_HT, but it appears that NO_HT packets can be sent on any channel type, so we do not need to change the channel type as long as the channel is correct.

* mac80211: Properly set work-item channel-type.Ben Greear2011-02-092-0/+3
| | | | | | | | | | Some were indirectly set to NO_HT (zero), but I think it's better to explicitly set it in case the enum ever changes. In cfg.c, it seems the channel-type was just ignored (and thus always set to NO_HT). Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* Bluetooth: Add set_io_capability management commandJohan Hedberg2011-02-084-2/+62
| | | | | | | | | | This patch adds a new set_io_capability management command which is used to set the IO capability for Secure Simple Pairing (SSP) as well as the Security Manager Protocol (SMP).

* Bluetooth: Add get_connections managment interface commandJohan Hedberg2011-02-081-0/+72
| | | | | | | | | | | This patch adds a get_connections command to the management interface. With this command userspace can get the current list of connected devices. Typically this command would only be used once when enumerating existing adapters. After that the connected and disconnected events are used to track connections.

* Bluetooth: Add support for connect failed management eventJohan Hedberg2011-02-082-1/+15
| | | | | | | | | | This patch add a new connect failed management event to track failures in connecting to remote devices.

* Bluetooth: Add disconnect managment commandJohan Hedberg2011-02-082-2/+126
| | | | | | | | | This patch adds a disconnect command to the managment interface. Using this command user space is able to force the disconnection of connected devices. The command maps directly to the Disconnect HCI command. Signed-off-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
* Bluetooth: Add connected/disconnected management eventsJohan Hedberg2011-02-082-5/+31

* Bluetooth: Implement link key handling for the management interfaceJohan Hedberg2011-02-083-0/+252
| | | | | | | | | | | This patch adds a management commands to feed the kernel with all stored link keys as well as remove specific ones or all of them. Once the load_keys command has been called the kernel takes over link key replies. A new_key event is also added to inform userspace of newly created link keys that should be stored permanently.

* Bluetooth: Add class of device control to the management interfaceJohan Hedberg2011-02-081-3/+118
| | | | | | | | | | | | | | This patch adds the possibility for user space to fully control the Class of Device value of local adapters. To control the service class bits each UUID that's added comes with a service class "hint" which acts as a mask of bits that the UUID needs to have enabled. The set_service_cache management command is used to make sure we queue up all UUID changes as user space initializes its drivers and then send a single HCI_Write_Class_of_Device command when initialization is complete.

* Bluetooth: Implement a more complete adapter initialization sequenceJohan Hedberg2011-02-081-1/+193
| | | | | | | | | | | | | Using the managment interface means that user space doesn't need to do any HCI command sending at all. This patch moves the remaining initialization commands from user space to the kernel side. The patch makes use of the new feature of __hci_request which allows the request to be dynamically modified while it is ongoing (something that is needed to react appropriately to the local features and the version of the adapter).

* Bluetooth: Remove page timeout setting from HCI init sequenceJohan Hedberg2011-02-081-4/+0
| | | | | | | | | User space should set the page timeout so there's no need to explicitly set it in the HCI init sequence. Even if user space fails to set it the controller default value will be used. Signed-off-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
* Bluetooth: Add controller side link key clearing to hci_init_reqJohan Hedberg2011-02-082-0/+19
| | | | | | | | | | | | The controller may have link keys in its own memory and these keys could be used for secure connections. However, since the interface to access these keys doesn't provide information about the key types (which would be needed to infer the level of security each key provides) using these keys is rather useless. Therefore, simply clear the controller side list in the initialization procedure. Signed-off-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
* Bluetooth: Add special handling with __hci_request and HCI_INITJohan Hedberg2011-02-081-8/+9
| | | | | | | | | | | | | | | | | | | | To support a more dynamic HCI initialization sequence the __hci_request behavior requires some more changes. Particularly, the init sequence should be able to have conditionals in it (sending some HCI commands depending on the outcome of a previous command) instead of being a fixed list as it is right now. The reasons for these additional requirements are the moving all previously user space driven initialization commands to the kernel side as well as the support the Low Energy controllers. To fulfull these requirements the init sequence is made the only special case for multi-command requests and req_last_cmd is renamed to init_last_cmd. The hci_send_cmd function is changed to update init_last_cmd as long as the HCI_INIT flag is set. Signed-off-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
* Bluetooth: Reject pairing requests when in non-pairable modeJohan Hedberg2011-02-081-2/+53
| | | | | | | | | | This patch adds the necessary logic to act accordingly when the HCI_PAIRABLE flag is not set. In that case PIN code replies as well as Secure Simple Pairing requests without a NoBonding requirement need to be rejected.

* Bluetooth: Implement UUID handling through the management interfaceJohan Hedberg2011-02-082-0/+139
| | | | | | | | | | | | | This patch adds methods to the management interface for userspace to notify the kernel of which services have been registered for specific adapters. This information is needed for setting the appropriate Class of Device value as well as the Extended Inquiry Response value. This patch doesn't actually implement setting of these values but just provides the storage of the UUIDs so the needed functionality can be built on top of it.

* Bluetooth: Implement set_pairable managment commandJohan Hedberg2011-02-082-23/+75
| | | | | | | | | | | | | | This patch implements a new set_pairable management command to control the pairable state of local adapters. The state is represented using a new HCI_PAIRABLE flag in the hci_dev struct. For backwards compatibility with older user space versions the HCI_PAIRABLE flag gets automatically set when the existence of an adapter is reported to user space through legacy methods and the HCI_MGMT flag is not set.

* Bluetooth: Add send_mode_rsp convenience function for mgmt.cJohan Hedberg2011-02-081-21/+29
| | | | | | | | | Several management commands have similar responses but they are not always sent asynchronously. To enable synchronous sending (from the managment command handler function) a send_mode_rsp function is added. Signed-off-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
* Bluetooth: Add flag to track managment controlled adaptersJohan Hedberg2011-02-081-0/+4
| | | | | | | | | | | This patch adds a HCI_MGMT flag to track adapters which are under the control of the management interface. This is needed to make sure that new kernels will work with old user space versions. I.e. behaviour which could break old user space versions (but is needed by the management interface) should not be exhibited when the HCI_MGMT flag is not set.

* Bluetooth: Add set_connectable management commandJohan Hedberg2011-02-082-7/+131
| | | | | | | | | | | This patch adds a set_connectable command as well as a corresponding event to the management interface. It's mainly useful for setting an adapter as connectable from a non-initialized state as well as setting an already initialized adapter as non-connectable (mostly useful for qualification purposes).

* Bluetooth: Add support for management powered eventJohan Hedberg2011-02-082-0/+14
| | | | | | | | This patch adds support for the powered event that's used to indicate to userspace when the powered state of a local adapter changes. Signed-off-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
* Bluetooth: Implement automatic setup procedure for local adaptersJohan Hedberg2011-02-082-2/+70
| | | | | | | | | | | | | | | | | | | | | | | | | This patch implements automatic initialization of basic information about newly registered Bluetooth adapters. E.g. the address and features are always needed so it makes sense for the kernel to automatically power on adapters and read this information. A new HCI_SETUP flag is added to track this state. In order to not consume unnecessary amounts of power if there isn't a user space available that could switch the adapter back off, a timer is added to do this automatically as long as no Bluetooth user space seems to be present. A new HCI_AUTO_OFF flag is added that user space needs to clear to avoid the automatic power off. Additionally, the management interface index_added event is moved to the end of the HCI_SETUP stage so a user space supporting the managment inteface has all the necessary information available for fetching when it gets notified of a new adapter. The HCI_DEV_REG event is kept in the same place as before since existing HCI raw socket based user space versions depend on seeing the kernels initialization sequence (hci_init_req) to determine when the adapter is ready for use.
