This patch adds new socket options for LE sockets since the existing L2CAP_OPTIONS socket option is not usable for LE. For now, the new socket options also require LE CoC support to be explicitly enabled to leave some playroom in case something needs to be changed in a backwards incompatible way. Signed-off-by:

Most of the values in L2CAP_OPTIONS are not applicable for LE and those that are have different semantics. It makes therefore sense to completely block this socket option for LE and add (in a separate patch) a new socket option for tweaking the values that do make sense (mainly the send and receive MTU). Legacy user space ATT code still depends on getsockopt for L2CAP_OPTIONS though so we need to plug a hole for that for backwards compatibility. Signed-off-by:

This patch adds tracking of L2CAP connection oriented channel local and remote credits to struct l2cap_chan and ensures that connect requests and responses contain the right values. Signed-off-by:

The LE connection oriented channels have their own mode with its own data transfer rules. In order to implement this properly we need to distinguish L2CAP channels operating in this mode from other modes. Signed-off-by:

The normal L2CAP Disconnect request and response are also used for LE connection oriented channels. Therefore, we can simply use the existing handler functions for terminating LE based L2CAP channels. Signed-off-by:

Sending of the L2CAP Disconnect request should also be performed for LE based channels. The proper thing to do is therefore to look at whether there's a PSM specified for the channel instead of looking at the link type. Signed-off-by:

We'll need to have a separate code path for LE based connection rejection so it's cleaner to move out the response construction code into its own function (and later a second one for LE). Signed-off-by:

Once connection oriented L2CAP channels over LE are supported they will need a completely separate handling from BR/EDR channels. Signed-off-by:
-
Johan Hedberg authored
The LE signaling PDU length is already calculated in the l2cap_le_sig_channel function so we can just pass the value to the various handler functions to avoid unnecessary recalculations (byte order conversions). Right now the only user is the connection parameter update procedure, but as new LE signaling operations become available (for connection oriented channels) they will also be able to make use of the value. Signed-off-by:

Johan Hedberg authored
With connection oriented L2CAP channels some code paths will be shared with BR/EDR links. It is therefore necessary to allow the l2cap_chan_check_security function to be usable also for LE links in addition to BR/EDR ones. This means that smp_conn_security() needs to be called instead of hci_conn_security() in the case of an LE link. Signed-off-by:
-
Johan Hedberg authored
Once connection oriented L2CAP channels become possible for LE we need to be able to specify the link type we're interested in when looking up L2CAP channels. Therefore, add a link_type parameter to the l2cap_global_chan_by_psm() function which gets compared to the address type associated with each l2cap_chan. Signed-off-by:

Johan Hedberg authored
Along with the L2CAP Connection Oriented Channels features it is now allowed to use both custom fixed CIDs as well as PSM based (connection oriented connections). Since the support for this (with the subsequent patches) is still on an experimental stage, add a module parameter to enable it. Signed-off-by:

The AES cipher is used in ECB mode by SMP and therefore doesn't use an IV (crypto_blkcipher_ivsize returns 0) so the code trying to set the IV was never getting called. Simply remove this code to avoid anyone from thinking it actually makes some difference. Signed-off-by:

This function was always just making a single get_random_bytes() call and always returning the value 0. It's simpler to just call get_random_bytes() directly where needed. Signed-off-by:

This patch enables autosuspend for Intel Bluetooth device. After btusb is loaded for Intel Bluetooth device, the power/control attribute contains "on" value by default which disables the autosuspend. Based on the USB PM document(Documentation/usb/power-management.txt), kernel disabled the autosuspend for all devices other than hub by default. "The USB specification states that all USB devices must support power management. Nevertheless, the sad fact is that many devices do not support it very well. You can suspend them all right, but when you try to resume them they disconnect themselves from the USB bus or they stop working entirely. This seems to be especially prevalent among printers and scanners, but plenty of other types of device have the same deficiency. For this reason, by default the kernel disables autosuspend (the power/control attribute is initialized to "on") for all devices other than hubs. Hubs, at least, appear to be reasonably well-behaved in this regard." This document also described how the driver can enables the autosuspend by using an USB api. "Drivers can enable autosuspend for their devices by calling usb_enable_autosuspend(struct usb_device *udev); in their probe() routine, if they know that the device is capable of suspending and resuming correctly. This is exactly equivalent to writing "auto" to the device's power/control attribute." For Intel Bluetooth device, the autosuspend needs to be enabled so the device can transit to LPM(Low Power Mode) and ULPM(Ultra LPM) states after receiving suspend message from the host.

hci_disconn_complete_evt() logic is more complicated than what it should be, making it hard to follow and add new features. So this patch does some code refactoring by handling the error cases in the beginning of the function and by moving the main flow into the first level of function scope. No change is done in the event handling logic itself. Besides organizing this messy code, this patch makes easier to add code for handling LE auto connection (which will be added in a further patch).

According to b644ba33 (patch that introduced HCI_CONN_MGMT_CONNECTED flag), the HCI_CONN_MGMT_CONNECTED flag tracks when mgmt has been notified about the connection. That being said, there is no point in calling mgmt_disconnect_failed() conditionally based on this flag. mgmt_disconnect_failed() removes pending MGMT_OP_DISCONNECT commands, it doesn't matter if that connection was notified or not. Moreover, if the Disconnection Complete event has status then we have nothing else to do but call mgmt_disconnect_failed() and return. Signed-off-by:

Some ARM versions of Chromebook need to download a new calibration data from host driver to firmware. They do have EEPROM but still need a piece of new calibration data in test mode. The cal-data is platform dependent. It's simpler and more feasible to use device tree based cal-data instead of configuration file based cal-data. This patch remove configuration file based cal-data downloading and replace it using cal-data from device tree. When CONFIG_OF is not selected, or the specific property is not present in the device tree, the calibration downloading will not happen.

There is an old Panasonic module with a Zeevo chip in there that is not really operating according to Bluetooth core specification when it comes to setting the IAC LAP for limited discoverable mode. For reference, this is the vendor information about this module: < HCI Command: Read Local Version Information (0x04|0x0001) plen 0 > HCI Event: Command Complete (0x0e) plen 12 Read Local Version Information (0x04|0x0001) ncmd 1 Status: Success (0x00) HCI version: Bluetooth 1.2 (0x02) - Revision 196 (0x00c4) LMP version: Bluetooth 1.2 (0x02) - Subversion 61 (0x003d) Manufacturer: Zeevo, Inc. (18) The module reports only the support for one IAC at a time. And that is totally acceptable according to the Bluetooth core specification since the minimum supported IAC is only one. < HCI Command: Read Number of Supported IAC (0x03|0x0038) plen 0 > HCI Event: Command Complete (0x0e) plen 5 Read Number of Supported IAC (0x03|0x0038) ncmd 1 Status: Success (0x00) Number of IAC: 1 The problem arises when trying to program two IAC into the module on a controller that only supports one. < HCI Command: Write Current IAC LAP (0x03|0x003a) plen 7 Number of IAC: 2 Access code: 0x9e8b00 (Limited Inquiry) Access code: 0x9e8b33 (General Inquiry) > HCI Event: Command Status (0x0f) plen 4 Write Current IAC LAP (0x03|0x003a) ncmd 1 Status: Unknown HCI Command (0x01) While this looks strange, but according to the Bluetooth core specification it is a legal operation. The controller has to ignore the other values and only program as many as it supports. This command shall clear any existing IACs and stores Num_Current_IAC and the IAC_LAPs in to the controller. If Num_Current_IAC is greater than Num_Support_IAC then only the first Num_Support_IAC shall be stored in the controller, and a Command Complete event with error code Success (0x00) shall be generated. This specific controller has a bug here and just returns an error. So in case the number of supported IAC is less than two and the limited discoverable mode is requested, now only the LIAC is written to the controller. < HCI Command: Write Current IAC LAP (0x03|0x003a) plen 4 Number of IAC: 1 Access code: 0x9e8b00 (Limited Inquiry) > HCI Event: Command Complete (0x0e) plen 4 Write Current IAC LAP (0x03|0x003a) ncmd 1 Status: Success (0x00) All other controllers that only support one IAC seem to handle this perfectly fine, but this fix will only write the LIAC for these controllers as well.
