2011-04-28Bluetooth: Add discovering event to the Management interfaceJohan Hedberg1-6/+34
This patch adds a new event to the Management interface to track when local adapters are discovering remote devices. For now this only tracks BR/EDR discovery procedures.

2011-04-19Bluetooth: Fix refcount balance for hci connectionVille Tervo1-2/+0
hci_io_capa_reply_evt() holds reference for hciconnection. It's useless since hci_io_capa_request_evt()/hci_simple_pair_complete_evt() already protects the connection.

2011-02-08Bluetooth: Implement link key handling for the management interfaceJohan Hedberg1-0/+51
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.

2011-02-08Bluetooth: Implement a more complete adapter initialization sequenceJohan Hedberg1-1/+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).

2011-02-08Bluetooth: Add controller side link key clearing to hci_init_reqJohan Hedberg1-0/+14
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>
2011-02-08Bluetooth: Reject pairing requests when in non-pairable modeJohan Hedberg1-2/+53

2011-02-08Bluetooth: Add set_connectable management commandJohan Hedberg1-5/+11
This patch adds a set_connectable command as well as a corresponding event to the management interface.

2011-01-19Bluetooth: Fix race condition with conn->sec_levelJohan Hedberg1-4/+5
The conn->sec_level value is supposed to represent the current level of security that the connection has. However, by assigning to it before requesting authentication it will have the wrong value during the authentication procedure. To fix this a pending_sec_level variable is added which is used to track the desired security level while making sure that sec_level always represents the current level of security.

2010-12-23Bluetooth: Fix __hci_request synchronization for hci_open_devJohan Hedberg1-10/+23
The initialization function used by hci_open_dev (hci_init_req) sends many different HCI commands. The __hci_request function should only return when all of these commands have completed (or a timeout occurs). Several of these commands cause hci_req_complete to be called which causes __hci_request to return prematurely. This patch fixes the issue by adding a new hdev->req_last_cmd variable which is set during the initialization procedure. The hci_req_complete function will no longer mark the request as complete until the command matching hdev->req_last_cmd completes.

2010-12-02Bluetooth: Automate remote name requestsJohan Hedberg1-18/+54
In Bluetooth there are no automatic updates of remote device names when they get changed on the remote side. Instead, it is a good idea to do a manual name request when a new connection gets created (for whatever reason) since at this point it is very cheap (no costly baseband connection creation needed just for the sake of the name request). So far userspace has been responsible for this extra name request but tighter control is needed in order not to flood Bluetooth controllers with two many commands during connection creation. It has been shown that some controllers simply fail to function correctly if they get too many (almost) simultaneous commands during connection creation. The simplest way to acheive better control of these commands is to move their sending completely to the kernel side. This patch inserts name requests into the sequence of events that the kernel performs during connection creation. It does this after the remote features have been successfully requested and before any pending authentication requests are performed. The code will work sub-optimally with userspace versions that still do the name requesting themselves (it shouldn't break anything though) so it is recommended to combine this with a userspace software version that doesn't have automated name requests.

2010-12-02Bluetooth: Create a unified authentication request functionJohan Hedberg1-14/+40

2010-11-09Bluetooth: Fix non-SSP auth request for HIGH security level socketsJohan Hedberg1-0/+6
When initiating dedicated bonding a L2CAP raw socket with HIGH security level is used. The kernel is supposed to trigger the authentication request in this case but this doesn't happen currently for non-SSP (pre-2.1) devices. The reason is that the authentication request happens in the remote extended features callback which never gets called for non-SSP devices. This patch fixes the issue by requesting also authentiation in the (normal) remote features callback in the case of non-SSP devices. This rule is applied only for HIGH security level which might at first seem unintuitive since on the server socket side MEDIUM is already enough for authentication. However, for the clients we really want to prefer the server side to decide the authentication requrement in most cases, and since most client sockets use MEDIUM it's better to be avoided on the kernel side for these sockets. The important socket to request it for is the dedicated bonding one and that socket uses HIGH security level. The patch is based on the initial investigation and patch proposal from Andrei Emeltchenko <endrei.emeltchenko@nokia.com>.
