In case the remote only provided P-192 or P-256 data for OOB pairing, then make sure that the data value pointers are correctly set. That way the core can provide correct information when remote OOB data present information have to be communicated. Signed-off-by:

Before setting the OOB data present flag with SMP pairing, check the newly introduced present tracking that actual OOB data values have been provided. The existence of remote OOB data structure does not actually mean that the correct data values are available. Signed-off-by:

When BR/EDR Secure Connections has been enabled, the OOB data present value can take 2 additional values. The host has to clearly provide details about if P-192 OOB data, P-256 OOB data or a combination of P-192 and P-256 OOB data is present. In case BR/EDR Secure Connections is not enabled or not supported, then check that P-192 OOB data is actually present and return the correct value based on that. Signed-off-by:

Instead of doing complex calculation every time the OOB data is used, just calculate the OOB data present value and store it with the OOB data raw values. Signed-off-by:

The wait_on_bit_timeout() is a simpler and race-free way of waiting for a bit to be cleared than the current code in btusb.c. This patch updates the code to use the helper function (its btusb copy - to be later updated to use a global one). Signed-off-by:

Johan Hedberg authored
The test for BTUSB_DOWNLOADING must be after adding to the wait queue and setting the TASK_INTERRUPTIBLE state. Otherwise the flag may get cleared after we test for it and we end up getting a timeout since schedule_timeout() waits for the full duration. This patch uses a wait_on_bit_timeout() + wake_up_bit(). To perform the task both race-free as well as in a much simpler way. Since there's no global wait_on_bit_timeout() helper yet (even though all the building blocks for it are in place) this patch creates a temporary local btusb copy of it until the global one has made it to upstream trees.

BugLink: https://bugs.launchpad.net/bugs/1400215 ath3k devices fail to load firmwares on xHCI buses, but work well on EHCI, this might be a compatibility issue between xHCI and ath3k chips. As my testing result, those chips will work on xHCI buses again with this patch. This workaround is from Qualcomm, they also did some workarounds in Windows driver. Signed-off-by:

This command should only be used if remote device reports that it supports extended features. Otherwise command will fail and connection will be dropped. Some devices support SSP but don't support extended features so current check for SSP support is not enought.

It is safe to call this function since it only remove the channel if it has been previously registered. Signed-off-by:

The Intel Bluetooth controllers can provide an additional exception info string when a hardware error event occurs. The core will now call hdev->hw_error to let the driver read out this information. This change will cause a reset of the hardware to bring it back into functional state and then read the Intel exception info string and print it along with the error information. Signed-off-by:

When receiving a HCI Hardware Error event, the controller should be assumed to be non-functional until issuing a HCI Reset command. The Bluetooth hardware errors are vendor specific and so add a new hdev->hw_error callback that drivers can provide to run extra code to handle the hardware error. After completing the vendor specific error handling perform a full reset of the Bluetooth stack by closing and re-opening the transport. Based-on-patch-by:

When HCI_Reset is issued the discovery state is assumed to be stopped. The hci_cc_reset() handler was trying to set the state but it was doing it without using the hci_discovery_set_state() function. Because of this e.g. the mgmt Discovering event could go without being sent. This patch fixes the code to use the hci_discovery_set_state() function instead of just blindly setting the state value.

There's a check in set_secure_conn() that's supposed to ensure that SSP is enabled before we try to request the controller to enable SC (since SSP is a pre-requisite for it). However, this check only makes sense for controllers actually supporting BR/EDR SC. If we have a 4.0 controller we're only interested in the LE part of SC and should therefore not be requiring SSP to be enabled. This patch adds an additional condition to check for lmp_sc_capable(hdev) before requiring SSP to be enabled. Signed-off-by:

The btusb_disconnect() callback calls hci_unregister_dev() which in turn calls btusb_close() if the HCI device is powered. The btusb_close() function in turn will call btusb_free_frags(). It's therefore unnecessary to have another call to btusb_free_frags() in the btusb_disconnect() function. Besides the redundancy the second call seems to also cause some strange stability issues which this patch then also fixes. Signed-off-by:

When loading the Intel firmware it can happen that the firmware loading complete vendor event arrives before the command complete event for the last firmware fragment. < HCI Command: Vendor (0x3f|0x0009) plen 7 01 02 fc 03 00 00 00 > HCI Event: Vendor (0xff) plen 5 06 00 00 00 00 > HCI Event: Command Complete (0x0e) plen 4 Vendor (0x3f|0x0009) ncmd 31 Status: Success (0x00) This is mainly caused by the fact that the vendor command and its command complete event are transported over the bulk endpoints. The firmware loading complete event however is send over the interrupt endpoint. So with just bad timing one event arrives before the other. Currently the code does not account for it. There are precautions for receiving firmware loading complete event quickly, but not for receiving it before the command complete. Introduce an extra flag that tracks when the firmware sending has completed from the driver point of view and track the completion of the firmware loading procedure with a different flag. That way the wakeup can be handled properly. Signed-off-by: -

The Intel Snowfield Peak devices do not come with Bluetooth firmware loaded and thus require a full download of the operational Bluetooth firmware when the device is connected via USB. Snowfield Peak devices start with a bootloader mode that only accepts a very limited set of HCI commands. The supported commands are enough to identify the hardware and select the right firmware to load. Previous patches to the btusb driver allow overwriting the handling for bulk receive endpoint packets and HCI events processing. The firmware loading makes heavy use of these new internal callbacks. This patch also introduces additional internal states to track if the device is in bootloader or operational mode. This allows for correct feedback about the firmware loading procedure.

l2cap/rfcomm/sco_sock_accept() are wait loops which may acquire sleeping locks. Since both wait loops and sleeping locks use task_struct.state to sleep and wake, the nested sleeping locks destroy the wait loop state. Use the newly-minted wait_woken() and DEFINE_WAIT_FUNC() for the wait loop. DEFINE_WAIT_FUNC() allows an alternate wake function to be specified; in this case, the predefined scheduler function, woken_wake_function(). This wait construct ensures wakeups will not be missed without requiring the wait loop to set the task state before condition evaluation. How this works: CPU 0 | CPU 1 | | is <condition> set? | no set <condition> | | wake_up_interruptible | woken_wake_function | set WQ_FLAG_WOKEN | try_to_wake_up | | wait_woken | set TASK_INTERRUPTIBLE | WQ_FLAG_WOKEN? yes | set TASK_RUNNING | | - loop - | | is <condition> set? | yes - exit wait loop Fixes "do not call blocking ops when !TASK_RUNNING" warnings in l2cap_sock_accept(), rfcomm_sock_accept() and sco_sock_accept().

This patch converts the Set Secure Connection HCI handling to use a HCI request instead of using a hard-coded callback in hci_event.c. This e.g. ensures that we don't clear the flags incorrectly if something goes wrong with the power up process (not related to a mgmt Set SC command). The code can also be simplified a bit since only one pending Set SC command is allowed, i.e. mgmt_pending_foreach usage is not needed. Signed-off-by:

The Add Remote OOB Data mgmt command should allow data to be passed for LE as well. This patch removes a left-over check for BDADDR_BREDR that should not be there anymore. Signed-off-by:

Before doing any other verifications, the add_remote_oob_data function should first check that the given address is valid. This patch adds such a missing check to the beginning of the function. Signed-off-by:

When BR/EDR is supported by a controller, then it is required to enable Secure Simple Pairing first before enabling the Secure Connections feature. Signed-off-by:

When a powered on dual-mode controller has been configured to operate as LE only with secure connections, then the BR/EDR side of things can not be switched back on. Do reconfigure the controller it first needs to be powered down. The secure connections feature is implemented in the BR/EDR controller while for LE it is implemented in the host. So explicitly forbid such a transaction to avoid inconsistent states. Signed-off-by:

The BR/EDR Secure Connections feature should only be enabled when the Secure Simple Pairing mode has been enabled first. However since secure connections is feature that is valid for BR/EDR and LE, this needs special handling. When enabling secure connections on a LE only configured controller, thent the BR/EDR side should not be enabled in the controller. This patches makes the BR/EDR Secure Connections feature depending on enabling Secure Simple Pairing mode first. Signed-off-by:
