2011-03-01Bluetooth: Fix possible NULL pointer dereference in cmd_completeSzymon Janc
It is now possible to create command complete event without specific reply data by passing NULL as reply with len 0. Check pointer before calling memcpy to avoid undefined behaviour. Signed-off-by: Szymon Janc <szymon.janc@tieto.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-02-28Bluetooth: Fix BT_L2CAP and BT_SCO in KconfigGustavo F. Padovan
If we want something "bool" built-in in something "tristate" it can't "depend on" the tristate config option. Report by DaveM: I give it 'y' just to make it happen, for both, and afterways no matter how many times I rerun "make oldconfig" I keep seeing things like this in my build: scripts/kconfig/conf --silentoldconfig Kconfig include/config/auto.conf:986:warning: symbol value 'm' invalid for BT_SCO include/config/auto.conf:3156:warning: symbol value 'm' invalid for BT_L2CAP Reported-by: David S.

2011-02-27Bluetooth: Validate data size before accessing mgmt commandsSzymon Janc
Crafted (too small) data buffer could result in reading data outside of buffer. Validate buffer size and return EINVAL if size is wrong. Signed-off-by: Szymon Janc <szymon.janc@tieto.com> Acked-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-02-27Bluetooth: Move index to common header in management interfaceSzymon Janc
Most mgmt commands and event are related to hci adapter. Moving index to common header allow to easily use it in command status while reporting errors. For those not related to adapter use MGMT_INDEX_NONE (0xFFFF) as index. Signed-off-by: Szymon Janc <szymon.janc@tieto.com> Acked-by: Johan Hedberg <johan.hedberg@nokia.com> Signed-off-by: Gustavo F.

The message for the initialization of the L2CAP layer was being printed twice. Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-02-25Bluetooth: remove unnecessary call to hci_sock_cleanupAnand Gadiyar
hci_sock_cleanup is already called after the sock_err label. It appears that we can drop this call. Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
2011-02-22Bluetooth: fix build break on hci_sock.cAnand Gadiyar
Linux-next as of 20110217 complains when building for OMAP1.

2011-02-21Bluetooth: Fix LE conn creationAnderson Briglia
This patch prevents a crash when remote host tries to create a LE link which already exists. i.e.: call l2test twice passing the same parameters.

2011-02-21Bluetooth: Fix unnecessary list traversal in mgmt_pending_removeJohan Hedberg
All of the places that need to call mgmt_pending_remove already have a pointer to the pending command, so searching for the command in the list doesn't make sense. The added benefit is that many places that previously had to call list_del + mgmt_pending_free can just call mgmt_pending_remove now.

2011-02-21Bluetooth: Fix inititial value for remote authentication requirementsJohan Hedberg
The remote authentication requirements for conections need to be initialized to 0xff (unknown) since it is possible that we receive a IO Capability Request before we have received information about the remote requirements.

2011-02-21Bluetooth: Add mgmt_auth_failed eventJohan Hedberg
To properly track bonding completion an event to indicate authentication failure is needed. This event will be sent whenever an authentication complete HCI event with a non-zero status comes. It will also be sent when we're acting in acceptor role for SSP authentication in which case the controller will send a Simple Pairing Complete event.

2011-02-21Bluetooth: Add mgmt_pair_device commandJohan Hedberg
This patch adds a new mgmt_pair_device which can be used to initiate a dedicated bonding procedure. Some extra callbacks are added to the hci_conn struct so that the pairing code can get notified of the completion of the procedure.

2011-02-16Bluetooth: Add connection parameter update responseClaudio Takahasi

Address the LE Connection Parameter Procedure initiated by the slave. Connection Interval Minimum and Maximum have the same range: 6 to 3200. Time = N * 1.25ms. Minimum shall be less or equal to Maximum. The Slave Latency field shall have a value in the range of 0 to ((connSupervisionTimeout / connIntervalMax) - 1). Latency field shall be less than 500. connSupervisionTimeout = Timeout Multiplier * 10 ms. Multiplier field shall have a value in the range of 10 to 3200.

2011-02-16Bluetooth: Add LE signaling commands handlingClaudio Takahasi
This patch splits the L2CAP command handling function in order to have a clear separation between the commands related to BR/EDR and LE. Commands and responses in the LE signaling channel are not being handled yet, command reject is sent to all received requests. Bluetooth Core Specification, Volume 3, Part A, section 4 defines the signaling packets formats and allowed commands/responses over the LE signaling channel.

2011-02-15Bluetooth: remove l2cap_load() hackGustavo F. Padovan

2011-02-14Bluetooth: Merge L2CAP and SCO modules into bluetooth.koGustavo F. Padovan
Actually doesn't make sense have these modules built separately. The L2CAP layer is needed by almost all Bluetooth protocols and profiles. There isn't any real use case without having L2CAP loaded. SCO is only essential for Audio transfers, but it is so small that we can have it loaded always in bluetooth.ko without problems. If you really doesn't want it you can disable SCO in the kernel config. Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi>
