2015-03-25Bluetooth: hci_uart: Add setup callbackLoic Poulain2-0/+12
Some Bluetooth controllers require initialization before being used (vendor config, firmware download). Add possibility for a HCI UART proto to implement this early init via the setup callback. Signed-off-by: Loic Poulain <loic.poulain@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-03-24Bluetooth: Filter list of supported commands/events for untrusted usersMarcel Holtmann1-7/+46
When the user of the management interface is not trusted, then it only has access to a limited set of commands and events. When providing the list of supported commands and events take the trusted vs untrusted status of the user into account and return different lists. This way the untrusted user knows exactly which commands it can execute and which events it can receive. So no guesswork needed.

2015-03-24Bluetooth: Implement the Add Advertising commandArman Uguray1-10/+273
This patch adds the most basic implementation for the "Add Advertisement" command. All state updates between the various HCI settings (POWERED, ADVERTISING, ADVERTISING_INSTANCE, and LE_ENABLED) has been implemented. The command currently supports only setting the advertising data fields, with no flags and no scan response data.

2015-03-24Bluetooth: Add data structure for advertising instanceArman Uguray2-0/+17
This patch introduces a new data structure to represent advertising instances that were added using the "Add Advertising" mgmt command. Initially an hci_dev structure will support only one of these instances at a time, so the current instance is simply stored as a direct member of hci_dev.

2015-03-22Bluetooth: Read Broadcom chip info for Apple Bluetooth devicesMarcel Holtmann1-1/+37
For the Apple Bluetooth devices that are Broadcom based, it makes sense to read the chip information. It is a single HCI command and might help gathering more information about these devices. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-03-22Bluetooth: Fix memory leak in le_scan_disable_work_complete()Johan Hedberg1-8/+9
The hci_request in le_scan_disable_work_complete() was being initialized in a general context but only used in a specific branch in the function (when simultaneous discovery is not supported). This patch moves the usage to be limited to the branch where hci_req_run() is actually called.

2015-03-21Bluetooth: Read Verbose Config Version Info for Broadcom devicesMarcel Holtmann1-0/+19
The Broadcom devices expose their chip id via Read Verbose Config Version Info command. While this information is not used at the moment, it might be useful for debugging purposes and so read it before patching the firmware. This makes it show up in dmesg and HCI traces taken for the system. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2015-03-20Bluetooth: Expose quirks through debugfsJakub Pawlowski1-0/+60

2015-03-20Bluetooth: Use HCI_MAX_AD_LENGTH constant instead hardcoded valueMarcel Holtmann1-2/+2

2015-03-20Bluetooth: Gracefully response to enabling LE on LE only devicesMarcel Holtmann1-2/+14
Currently the enabling of LE on LE only devices causes an error. This is a bit difference from other commands where trying to set the same existing settings causes a positive response.

2015-03-18cc2520: Add support for CC2591 amplifier.Brad Campbell3-8/+52
The TI CC2521 is an RF power amplifier that is designed to interface with the CC2520. Conveniently, it directly interfaces with the CC2520 and does not require any pins to be connected to a microcontroller/processor. Adding a CC2591 increases the CC2520's range, which is useful for border router and other wall-powered applications. Using the CC2591 with the CC2520 requires configuring the CC2520 GPIOs that are connected to the CC2591 to correctly set the CC2591 into TX and RX modes. Further, TI recommends that the CC2520_TXPOWER and CC2520_AGCCTRL1 registers are set differently to maximize the CC2591's performance. These settings are covered in TI Application Note AN065. This patch adds an optional `amplified` field to the cc2520 entry in the device tree. If present, the CC2520 will be configured to operate with a CC2591. The expected pin mapping is: CC2520 GPIO0 --> CC2591 EN CC2520 GPIO5 --> CC2591 PAEN Signed-off-by: Brad Campbell <bradjc5@gmail.com> Acked-by: Varka Bhadram <varkabhadram@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-03-18cc2520: Do not store platform_data in spi_deviceBrad Campbell1-49/+46
Storing the `platform_data` struct inside of the SPI struct when using the device tree allows for a later function to edit the content of that struct. This patch refactors the `cc2520_get_platformat_data` function to accept a pointer to a `cc2520_platform_data` struct and populates the fields inside of it.

2015-03-17Bluetooth: Add workaround for broken OS X legacy SMP pairingJohan Hedberg1-8/+67
OS X version 10.10.2 (and possibly older versions) doesn't support LE Secure Connections but incorrectly copies all authentication request bits from a Security Request to its Pairing Request. The result is that an SC capable initiator (such as BlueZ) will think OS X intends to do SC when in fact it's incapable of it: < ACL Data TX: Handle 3585 flags 0x00 dlen 6 SMP: Security Request (0x0b) len 1 Authentication requirement: Bonding, No MITM, SC, No Keypresses (0x09) > ACL Data RX: Handle 3585 flags 0x02 dlen 11 SMP: Pairing Request (0x01) len 6 IO capability: KeyboardDisplay (0x04) OOB data: Authentication data not present (0x00) Authentication requirement: Bonding, No MITM, SC, No Keypresses (0x09) Max encryption key size: 16 Initiator key distribution: EncKey (0x01) Responder key distribution: EncKey IdKey Sign (0x07) < ACL Data TX: Handle 3585 flags 0x00 dlen 11 SMP: Pairing Response (0x02) len 6 IO capability: NoInputNoOutput (0x03) OOB data: Authentication data not present (0x00) Authentication requirement: Bonding, No MITM, SC, No Keypresses (0x09) Max encryption key size: 16 Initiator key distribution: EncKey (0x01) Responder key distribution: EncKey Sign (0x05) The pairing eventually fails when we get an unexpected Pairing Confirm PDU instead of a Public Key PDU: > ACL Data RX: Handle 3585 flags 0x02 dlen 21 SMP: Pairing Confirm (0x03) len 16 Confim value: bcc3bed31b8f313a78ec3cce32685faf It is only at this point that we can speculate that the remote doesn't really support SC. This patch creates a workaround for the just-works model, however the MITM case is unsolvable because the OS X user has already been requested to enter a PIN which we're now expected to randomly generate and show the user (i.e. a chicken-and-egg problem).

2015-03-17Bluetooth: Move generic mgmt command dispatcher to hci_sock.cJohan Hedberg3-115/+115
The mgmt.c file should be reserved purely for HCI_CHANNEL_CONTROL. The mgmt_control() function in it is already completely generic and has a single user in hci_sock.c. This patch moves the function there and renames it a bit more appropriately to hci_mgmt_cmd() (as it's a command dispatcher).

2015-03-17Bluetooth: Add hdev_init callback for HCI channelsJohan Hedberg2-2/+4
In order to make the mgmt command handling more generic we can't have a direct call to mgmt_init_hdev() from mgmt_control(). This patch adds a new callback to struct hci_mgmt_chan. And sets it to point to the mgmt_init_hdev() function for the HCI_CHANNEL_CONTROL instance. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-03-17Bluetooth: Add generic mgmt helper APIJohan Hedberg4-197/+265
There are several mgmt protocol features that will be needed by more than just the current HCI_CHANNEL_CONTROL. These include sending generic events as well as handling pending commands. This patch moves these functions out from mgmt.c to a new mgmt_util.c file. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-03-17Bluetooth: Add channel parameter to mgmt_pending_find() APIJohan Hedberg1-46/+62
To be able to have pending commands for different HCI channels we need to be able to distinguish for which channel a command was sent to. The channel information is already part of the socket data and can be fetched using the recently added hci_sock_get_channel() function. To not require all mgmt.c code to pass an extra channel parameter this patch also adds a helper pending_find() & pending_find_data() functions which act as a wrapper to the new mgmt_pending_find() & mgmt_pending_find_data() APIs.

2015-03-17Bluetooth: Add simultaneous dual mode scanJakub Pawlowski3-10/+70
When doing scan through mgmt api, some controllers can do both le and classic scan at same time. They can be distinguished by HCI_QUIRK_SIMULTANEOUS_DISCOVERY set.

Some controllers allow both LE scan and BR/EDR inquiry to run at the same time, while others allow only one, LE SCAN or BR/EDR inquiry at given time. Since this is specific to each controller, add a new quirk setting that allows drivers to tell the core wether given controller can do both LE scan and BR/EDR inquiry at same time.

This patch fix an issue when at86rf230_read_subreg was successful. The function at86rf230_read_subreg will directly call regmap_read which returns zero on successful. Nobody figured out issues yet because it was only necessary to evaluate dvdd state while probing. This could make trouble because the stack variable could have an random value. The function is also used by reset the irq line before requesting irq, but the value isn't evaluated afterwards.
