2012-02-24Bluetooth: mgmt: Track pending class changesJohan Hedberg
This patch adds a flag to track pending changes to the class of device. This is needed since we cannot cleanly handle multiple simultaneous commands and need to return a "busy" error status in the mgmt commands that might trigger a class change.

2012-02-23Bluetooth: Add hdev->short_name for EIR generationJohan Hedberg
It's possible to provide a short name through the mgmt interface and this name can be used for EIR generation when the full name doesn't fit there. This patch adds the preliminary tracking of the provided short name. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Acked-by: Marcel Holtmann <marcel@holtmann.org>

2012-02-20Bluetooth: Remove HCI notifier handlingMarcel Holtmann

2012-02-20Bluetooth: Split sending for HCI raw and control socketsMarcel Holtmann

2012-02-19Bluetooth: mgmt: Move status parameters into the cmd_complete headerJohan Hedberg
Instead of having status paramters part of each individual command response it's simpler to just have the status as part of the command complete header.

2012-02-19Bluetooth: Interleaved discovery supportAndre Guedes
This patch adds interleaved discovery support to MGMT Start Discovery command. In case interleaved discovery is not supported (not a dual mode device), we perform BR/EDR or LE-only discovery according to the device capabilities.

2012-02-19Bluetooth: Merge INQUIRY and LE_SCAN discovery statesAndre Guedes
This patch merges DISCOVERY_INQUIRY and DISCOVERY_LE_SCAN states into a new state called DISCOVERY_FINDING. From the discovery perspective, we are pretty much worried about to know just if we are finding devices than what exactly phase of "finding devices" (inquiry or LE scan) we are currently running. Besides, to know if the controller is performing inquiry or LE scan we should check HCI_INQUIRY or HCI_LE_SCAN bits in hdev flags. Moreover, merging this two states will simplify the discovery state machine and will keep interleaved discovery implementation simpler.

2012-02-19Bluetooth: Prepare start_discoveryAndre Guedes
This patch does some code refactoring in start_discovery function in order to prepare it for interleaved discovery support. MGMT_ADDR_* macros were moved to hci_core.h since they are now used to define discovery type macros. Discovery type macros were defined according to mgmt-api.txt specification: Possible values for the Type parameter are a bit-wise or of the following bits: 1 BR/EDR 2 LE Public 3 LE Random By combining these e.g. the following values are possible: 1 BR/EDR 6 LE (public & random) 7 BR/EDR/LE (interleaved discovery) Signed-off-by: Andre Guedes <andre.guedes@openbossa.org> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2012-02-15Bluetooth: Remove usage of __cancel_delayed_work()Ulisses Furquim
__cancel_delayed_work() is being used in some paths where we cannot sleep waiting for the delayed work to finish.

Replace the calls with safer cancel_delayed_work() version which spins until the timer handler finishes on other CPUs and cancels the delayed work.

2012-02-15Bluetooth: silence lockdep warningOctavian Purdila
Since bluetooth uses multiple protocols types, to avoid lockdep warnings, we need to use different lockdep classes (one for each protocol type). This is already done in bt_sock_create but it misses a couple of cases when new connections are created. This patch corrects that to fix the following warning: <4>[ 1864.732366] ======================================================= <4>[ 1864.733030] [ INFO: possible circular locking dependency detected ] <4>[ 1864.733544] 3.0.16-mid3-00007-gc9a0f62 #3 <4>[ 1864.733883] ------------------------------------------------------- <4>[ 1864.734408] t.android.btclc/4204 is trying to acquire lock: <4>[ 1864.734869] (rfcomm_mutex){+.+.+.}, at: [<c14970ea>] rfcomm_dlc_close+0x15/0x30 <4>[ 1864.735541] <4>[ 1864.735549] but task is already holding lock: <4>[ 1864.736045] (sk_lock-AF_BLUETOOTH){+.+.+.}, at: [<c1498bf7>] lock_sock+0xa/0xc <4>[ 1864.736732] <4>[ 1864.736740] which lock already depends on the new lock. <4>[ 1864.736750] <4>[ 1864.737428] <4>[ 1864.737437] the existing dependency chain (in reverse order) is: <4>[ 1864.738016] <4>[ 1864.738023] -> #1 (sk_lock-AF_BLUETOOTH){+.+.+.}: <4>[ 1864.738549] [<c1062273>] lock_acquire+0x104/0x140 <4>[ 1864.738977] [<c13d35c1>] lock_sock_nested+0x58/0x68 <4>[ 1864.739411] [<c1493c33>] l2cap_sock_sendmsg+0x3e/0x76 <4>[ 1864.739858] [<c13d06c3>] __sock_sendmsg+0x50/0x59 <4>[ 1864.740279] [<c13d0ea2>] sock_sendmsg+0x94/0xa8 <4>[ 1864.740687] [<c13d0ede>] kernel_sendmsg+0x28/0x37 <4>[ 1864.741106] [<c14969ca>] rfcomm_send_frame+0x30/0x38 <4>[ 1864.741542] [<c1496a2a>] rfcomm_send_ua+0x58/0x5a <4>[ 1864.741959] [<c1498447>] rfcomm_run+0x441/0xb52 <4>[ 1864.742365] [<c104f095>] kthread+0x63/0x68 <4>[ 1864.742742] [<c14d5182>] kernel_thread_helper+0x6/0xd <4>[ 1864.743187] <4>[ 1864.743193] -> #0 (rfcomm_mutex){+.+.+.}: <4>[ 1864.743667] [<c1061ada>] __lock_acquire+0x988/0xc00 <4>[ 1864.744100] [<c1062273>] lock_acquire+0x104/0x140 <4>[ 1864.744519] [<c14d2c70>] __mutex_lock_common+0x3b/0x33f <4>[ 1864.744975] [<c14d303e>] mutex_lock_nested+0x2d/0x36 <4>[ 1864.745412] [<c14970ea>] rfcomm_dlc_close+0x15/0x30 <4>[ 1864.745842] [<c14990d9>] __rfcomm_sock_close+0x5f/0x6b <4>[ 1864.746288] [<c1499114>] rfcomm_sock_shutdown+0x2f/0x62 <4>[ 1864.746737] [<c13d275d>] sys_socketcall+0x1db/0x422 <4>[ 1864.747165] [<c14d42f0>] syscall_call+0x7/0xb Signed-off-by: Octavian Purdila <octavian.purdila@intel.com> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2012-02-15Bluetooth: l2cap_set_timer needs jiffies as timeout valueAndrzej Kaczmarek
After moving L2CAP timers to workqueues l2cap_set_timer expects timeout value to be specified in jiffies but constants defined in miliseconds are used. This makes timeouts unreliable when CONFIG_HZ is not set to 1000. __set_chan_timer macro still uses jiffies as input to avoid multiple conversions from/to jiffies for sk_sndtimeo value which is already specified in jiffies.

2012-02-13Bluetooth: Introduce to_hci_connDavid Herrmann
This avoids using the dev_set/get_drvdata() functions to retrieve a pointer to our own structure. We can use simple pointer arithmetic here. The drvdata field is actually not needed by any other code-path but this makes the code more consistent with hci_dev.

2012-02-13Bluetooth: Introduce to_hci_dev()David Herrmann
We currently use dev_set_drvdata to keep a pointer to ourself. This doesn't make sense as we are the bus and not a driver. Therefore, introduce to_hci_dev() so we can get a struct hci_dev pointer from a struct device pointer. dev_set/get_drvdata() is reserved for drivers that provide a device and not for the bus using the device. The bus can use simple pointer arithmetic to retrieve its private data.

2012-02-13Bluetooth: Add Device Unpaired mgmt eventJohan Hedberg
This patch add a new Device Unpaired mgmt event. This will be sent to all mgmt sockets except the one that requested unpairing (that socket will get a command complete instead). The event is also reserved for future SMP updates where a remote device will be able to request pairing revocation from us.
