commit 50143a433b70e3145bcf8a4a4e54f0c11bdee32b upstream.
When inquiry is canceled through the HCI_Cancel_Inquiry command there is
no Inquiry Complete event generated. Instead, all we get is the command
complete for the HCI_Inquiry_Cancel command. This means that we must
call the hci_discovery_set_state() function from the respective command
complete handler in order to ensure that user space knows the correct
discovery state.

commit ba15a58b179ed76a7e887177f2b06de12c58ec8f upstream.
From the Bluetooth Core Specification 4.1 page 1958:
"if both devices have set the Authentication_Requirements parameter to
one of the MITM Protection Not Required options, authentication stage 1
shall function as if both devices set their IO capabilities to
DisplayOnly (e.g., Numeric comparison with automatic confirmation on
both devices)"
So far our implementation has done user confirmation for all just-works
cases regardless of the MITM requirements, however following the
specification to the word means that we should not be doing confirmation
when neither side has the MITM flag set.

commit 9eb1fbfa0a737fd4d3a6d12d71c5ea9af622b887 upstream.
Commit 1c2e004183178 introduced an event handler for the encryption key
refresh complete event with the intent of fixing some LE/SMP cases.
However, this event is shared with BR/EDR and there we actually want to
act only on the auth_complete event (which comes after the key refresh).
If we do not do this we may trigger an L2CAP Connect Request too early
and cause the remote side to return a security block error.

commit 5981a8821b774ada0be512fd9bad7c241e17657e upstream.
This patch fixes authentication failure on LE link re-connection when
BlueZ acts as slave (peripheral). LTK is removed from the internal list
after its first use causing PIN or Key missing reply when re-connecting
the link. The LE Long Term Key Request event indicates that the master
is attempting to encrypt or re-encrypt the link.
Pre-condition: BlueZ host paired and running as slave.
How to reproduce(master):
1) Establish an ACL LE encrypted link
2) Disconnect the link
3) Try to re-establish the ACL LE encrypted link (fails)

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 b644ba336 (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.

The device blacklist is not taking care of the address type. Actually
store the address type in the list entries and also use them when
looking up addresses in the table.
This is actually a serious bug. When adding a LE public address to

is not the expected behavior.

a bit of complicated code with the exported hci_udpate_ad function that

LE controllers will automatically disable advertising whenever they
accept a new connection. In order not to fall out of sync with the
advertising setting we need to re-enable advertising whenever the last
LE connection drops. A failure to re-enable advertising should cause the

This patch introduces a new mgmt command for enabling/disabling BR/EDR
functionality. This can be convenient when one wants to make a dual-mode
controller behave like a single-mode one. The command is only available
for dual-mode controllers and requires that LE is enabled before using
it. The BR/EDR setting can be enabled at any point, however disabling it
requires the controller to be powered off (otherwise a "rejected"
response will be sent).
Disabling the BR/EDR setting will automatically disable all other BR/EDR
related settings.

as a preparation for adding advertising support, since when LE is

While playing the peripheral role, the host gets a LE Long Term Key
Request Event from the controller when a connection is established
with a bonded device. The host then informs the LTK which should be
used for the connection. Once the link is encrypted, the host gets
an Encryption Change Event.
Therefore we should set conn->pending_sec_level instead of conn->
sec_level in hci_le_ltk_request_evt. This way, conn->sec_level is
properly updated in hci_encrypt_change_evt.
Moreover, since we have a LTK associated to the device, we have at
least BT_SECURITY_MEDIUM security level.

When initiating a transparent eSCO connection, make use of T2 settings
at first try. T2 is the recommended settings from HFP 1.6 WideBand
Speech. Upon connection failure, try T1 settings.
When CVSD is requested and eSCO is supported, try to establish eSCO
connection using S3 settings. If it fails, fallback in sequence to S2,
S1, D1, D0 settings.
To know which setting should be used, conn->attempt is used. It
indicates the currently ongoing SCO connection attempt and can be used
as the index for the fallback settings table.
These setting and the fallback order are described in Bluetooth HFP 1.6
specification p. 101.

Synchronous Connection Complete event can return error "Connection

Handling this error is required for SCO connection fallback. This error
happens when the server tried to accept the connection but failed to

This error code has been verified experimentally by sending a T2 request
to a T1 only SCO listener.

In order to have a better HCI error handling in interleaved discovery
functionality, we should use the HCI request framework.
This patch updates le_scan_disable_work function so it uses the
HCI request framework instead of the hci_send_cmd helper. A complete
callback is registered (le_scan_disable_work_complete function) so we
are able to trigger the inquiry procedure (if we are running the
interleaved discovery) or to stop the discovery procedure (if we are
running LE-only discovery).
This patch also removes the extra logic in hci_cc_le_set_scan_enable
to trigger the inquiry procedure and the mgmt_interleaved_discovery

The local and remote features are organized by page number. Page 0
are the LMP features, page 1 the host features, and any pages beyond 1
features that future core specification versions may define. So far
we've only had the first two pages and two separate variables has been
convenient enough, however with the introduction of Core Specification
Addendum 4 there are features defined on page 2.
Instead of requiring the addition of a new variable each time a new page
number is defined, this patch refactors the code to use a single table
for the features. The patch needs to update both the hci_dev and
hci_conn structures since there are macros that depend on the features
being represented in the same way in both of them.
