Bluetooth: Pass initiator/acceptor information to hci_conn_security()

2014-07-17T12:39:39Z

We're interested in whether an authentication request is because of a remote or local action. So far hci_conn_security() has been used both for incoming and outgoing actions (e.g. RFCOMM or L2CAP connect requests) so without some modifications it cannot know which peer is responsible for requesting authentication. This patch adds a new "bool initiator" parameter to hci_conn_security() to indicate which side is responsible for the request and updates the current users to pass this information correspondingly.

Bluetooth: Convert L2CAP ident spinlock into a mutex

2014-07-13T19:32:45Z

The spinlock protecting the L2CAP ident number can be converted into a mutex since the whole processing is run in a workqueue. So instead of using a spinlock, just use a mutex here. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Update the list of L2CAP fixed channels

2014-07-11T10:57:50Z

The list of L2CAP fixed channels increased with newer versions of the specification. This just updates the constants for it. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: 6LoWPAN: Use connected oriented channel instead of fixed one

2014-07-03T15:42:44Z

Create a CoC dynamically instead of one fixed channel for communication to peer devices. Signed-off-by: Jukka Rissanen Signed-off-by: Marcel Holtmann

Bluetooth: Provide L2CAP ops callback for memcpy_fromiovec

2014-07-03T15:42:43Z

The highly optimized TX path for L2CAP channels and its fragmentation within the HCI ACL packets requires to copy data from user provided IO vectors and also kernel provided memory buffers. This patch allows channel clients to provide a memcpy_fromiovec callback to keep this optimized behavior, but adapt it to kernel vs user memory for the TX path. For all kernel internal L2CAP channels, a default implementation is provided that can be referenced. In case of A2MP, this fixes a long-standing issue with wrongly accessing kernel memory as user memory. This patch originally by Marcel Holtmann.

Bluetooth: Use explicit header and body length for L2CAP SKB allocation

2014-07-03T15:42:42Z

When allocating the L2CAP SKB for transmission, provide the upper layers with a clear distinction on what is the header and what is the body portion of the SKB. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Assign L2CAP socket priority when allocating SKB

2014-07-03T15:42:41Z

The SKB for L2CAP sockets are all allocated in a central callback in the socket support. Instead of having to pass around the socket priority all the time, assign it to skb->priority when actually allocating the SKB. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Use const for struct l2cap_ops field

2014-07-03T15:42:41Z

The struct l2cap_ops field should not allow any modifications and thus it is better declared as const. Signed-off-by: Marcel Holtmann Signed-off-by: Johan Hedberg

Bluetooth: Fix updating Identity Address in L2CAP channels

2014-02-18T19:48:55Z

When we receive a remote identity address during SMP key distribution we should ensure that any associated L2CAP channel instances get their address information correspondingly updated (so that e.g. doing getpeername on associated sockets returns the correct address). This patch adds a new L2CAP core function l2cap_conn_update_id_addr() which is used to iterate through all L2CAP channels associated with a connection and update their address information.

Bluetooth: Enable LE L2CAP CoC support by default

2014-02-14T21:39:12Z

Now that the LE L2CAP Connection Oriented Channel support has undergone a decent amount of testing we can make it officially supported. This patch removes the enable_lecoc module parameter which was previously needed to enable support for LE L2CAP CoC. Signed-off-by: Johan Hedberg Signed-off-by: Marcel Holtmann
