The L2CAP socket parameter for CID are actually provided in little endian. So convert our constants into little endian before comparing them. Signed-off-by:

Right now we do not allow user space to use connection oriented channels on LE, and the only CID that can be used is the Attribute Protocol one. These restrictions went away together with the recent refactoring of the L2CAP code, but this patch puts them back to their appropriate places. Signed-off-by:

This function should be operating on scan_rsp_data_len and scan_rsp_data and not the advertising data variables. Signed-off-by:

This seems to be a left-over. The module parameter enable_hs has been removed, but its extern declaration is still present. It is not needed anymore, so just remove it. Signed-off-by:

The SMP CID is only defined for LE transports. Instead of returning an error from smp_sig_channel() in this case (which would cause a disconnection) just return 0 to ignore the data, which is consistent with the behavior for other unknown CIDs. Signed-off-by:

The A2MP CID is only valid for BR/EDR transports. We should ignore A2MP data on non-BR/EDR links and refuse to create an amp_mgr object. Signed-off-by:

Now that the only reason code this function can return is L2CAP_REJ_NOT_UNDERSTOOD we can just do the necessary assignment without needing a separate function at all. Signed-off-by:

There is no command handler that would return an EMSGSIZE error, so just remove this mapping from the l2cap_err_to_reason function. Signed-off-by:

When the reason code in the L2CAP command reject is "invalid CID" there should be four additional bytes of data in the PDU, namely the source and destination CIDs (which should be zero if one or both are not applicable). This patch fixes all occurrences of such errors to return the right kind of PDU. Signed-off-by:

The constants for advertising event types have been defined twice. So remove one copy of it. Signed-off-by:

Since there is update_scan_rsp_data, it is also better to use the clear name update_adv_data instead of update_ad. Signed-off-by:

The scan response data is a better place to store the device name since it has more space available and is also enforcing privacy. When the controller is advertising, the connectable setting decides if ADV_IND or ADV_NONCONN_IND is used. In case of ADV_IND, the remote side is allowed to request the scan response data. Same as with BR/EDR where either EIR is used or a remote name request. In non-connectable mode, the device name is not available since it is not allowed to request scan response data. Same as in BR/EDR where the device is non-discoverable and no name requests are answered. Signed-off-by:

On controller power on and when enabling LE functionality, make sure that also the scan response data is correctly set. Signed-off-by:

The scan response data needs to be stored in HCI device and so add a buffer for it and also ensure to clear it when resetting the controller. Signed-off-by:

Rename the create_ad function into create_adv_data to make it clear that it is used to create the advertising data. This is important since later on a function adding the scan response data will be added. Signed-off-by:

In this case the replacement by l2cap_chan_ready() doesn't change the code flow, the same operations will executed plus two others that have no effect: the use of the parent socket, that a non-oriented channel doesn't have and the reset of conf_state, which is also fine since the connection is ready at this point.

We need to remove all direct access of struct sock from L2CAP core. This change is pretty simple and just add a new L2CAP channel callback to do the work in the L2CAP socket side. Signed-off-by:

As part of the work to remove struct sock from l2cap_core.c and make it more generic we remove in this commit the direct access to sk->sk_sndtimeo member. This objective of this change is purely remove sk usage from l2cap_core.c Now we have a new l2cap ops to get the current value of sk->sndtimeo. A l2cap_chan_no_get_sndtimeo was added for users of L2CAP that doesn't need to set a timeout. Signed-off-by:

l2cap_state_change_and_error() introduces the ability to update a l2cap_user with changes in channel's state and error code with just one call. The main reason for this is to avoid race conditions between and setting the state and then the error. Otherwise we would need to release the lock between both operations. This is another step of an ongoing work to make l2cap_core.c totally independent from l2cap's struct sock. Signed-off-by:

Instead of creating an new function pointer to report errors we are just reusing state_change for that and there is a simple reason for this, one place in the l2cap_core.c code needs, in a locked sk, set both the sk_state and sk_err. If we create two different functions for this we would need to release the lock between the two operation putting the socket in non desired state. The change is transparent to the l2cap_core.c code, user that only needs to set the state won't need any modification. This is another step of an ongoing work to make l2cap_core.c totally independent from l2cap's struct sock. Signed-off-by:

When the discoverable timeout triggers and limited discoverable mode was used, then the class of device needs to be updated to remove the limited discoverable bit. To keep the class of device logic in a central place, expose a new function mgmt_discoverable_timeout that can be called from the timeout callback. In case the class of device value needs updating, it will add the HCI command to the transaction. Signed-off-by:

The limited discoverable mode should be used when a device is only discoverable for a certain amount of time and after that it returns back into being non-discoverable. This adds another option to the set discoverable management command to clearly distinguish limited discoverable from general discoverable mode. While the general discoverable mode can be set with a specific timeout or as permanent setting, the limited discoverable mode requires a timeout. The timeout is flexible and the kernel will not enforce any specific limitations. That GAP part of this is required by userspace to enforce according to the Bluetooth core specification. Devices in limited discoverable mode can still be found by the general discovery procedure. It is mandatory that a device sets both GIAC and LIAC when entering limited discoverable mode.

This patch just adds the HCI command structure for configuring the current IAC LAP setting. The length of the command is variable and supports more than two IAC. However since there is only general discoverable and limited discoverable modes, this can be limited to two possible IACs. Signed-off-by:
