2012-06-14Bluetooth: Fix sending HCI_Disconnect only when connectedVishal Agarwal
HCI_Disconnect should only be sent after connection is established. If connection is not yet established and HCI_Disconnect is called then disconnection complete will be received with a handle which does not exist and hence this event will be ignored. But as mgmt.c will not receive this event, its variable for pending command is not cleared.This will result in future Disconnect commands for that BD Address to be blocked with error busy.

2012-06-12Bluetooth: Fix using uninitialized option in RFCModeSzymon Janc
If remote device sends bogus RFC option with invalid length, undefined options values are used. Fix this by using defaults when remote misbehaves.

2012-06-09Bluetooth: Add support for encryption key refreshJohan Hedberg
With LE/SMP the completion of a security level elavation from medium to high is indicated by a HCI Encryption Key Refresh Complete event. The necessary behavior upon receiving this event is a mix of what's done for auth_complete and encryption_change, which is also where most of the event handling code has been copied from.

2012-06-08Bluetooth: Fix SMP security elevation from medium to highJohan Hedberg

2012-06-08Bluetooth: Fix deadlock and crash when SMP pairing times outJohan Hedberg
The l2cap_conn_del function tries to cancel_sync the security timer, but when it's called from the timeout function itself a deadlock occurs. Subsequently the "hcon->l2cap_data = NULL" that's supposed to protect multiple calls to l2cap_conn_del never gets cleared and when the connection finally drops we double free's etc which will crash the kernel. This patch fixes the issue by using the HCI_CONN_LE_SMP_PEND for protecting against this. The same flag is also used for the same purpose in other places in the SMP code.

2012-06-08Bluetooth: Fix LE pairing completion on connection failureVishal Agarwal
For BR/EDR pairing is assumed to be finished when connection is done. For LE if connection is successful it did not necessarily mean that pairing is also done but if the connection is unsuccessful it should be assumed that pairing procedure is also finished. This patch registers a new function with connect_cfm_cb callback for LE link which sends the pairing complete signal to user space if connection is unsuccessful.

2012-05-16Bluetooth: Lock the L2CAP channel when sendingMat Martineau
The ERTM and streaming mode transmit queue must only be accessed while the L2CAP channel lock is held. Locking the channel before calling l2cap_chan_send ensures that multiple threads cannot simultaneously manipulate the queue when sending and receiving concurrently. L2CAP channel locking had previously moved to the l2cap_chan struct instead of the associated socket, so some of the old socket locking can also be removed in this patch.

2012-05-16Bluetooth: Restore locking semantics when looking up L2CAP channelsMat Martineau
As the comment for l2cap_get_chan_by_scid indicated, the function used to return a locked socket. The lock for the socket was acquired while the channel list was also locked. When locking was moved over to the l2cap_chan structure, the channel lock was no longer acquired with the channel list still locked. This made it possible for the l2cap_chan to be deleted after conn->chan_lock was released but before l2cap_chan_lock was called. Making the call to l2cap_chan_lock before releasing conn->chan_lock makes it impossible for the l2cap_chan to be deleted at the wrong time.

2012-05-16Bluetooth: Fix a redundant and problematic incoming MTU checkMat Martineau
The L2CAP MTU for incoming data is verified differently depending on the L2CAP mode, so the check is best performed in a mode-specific context. Checking the incoming MTU before HCI fragment reassembly is a layer violation and assumes all bytes after the standard L2CAP header are L2CAP data. This approach causes issues with unsegmented ERTM or streaming mode frames, where there are additional enhanced or extended headers before the data payload and possible FCS bytes after the data payload. A valid frame could be as many as 10 bytes larger than the MTU. Removing this code is the best fix, because the MTU is checked later on for all L2CAP data frames (connectionless, basic, ERTM, and streaming). This also gets rid of outdated locking (socket instead of l2cap_chan) and an extra lookup of the channel ID.
