Currently it is not possible to determine if the static address is used
by the controller. It is also not possible to determine if using a
static on a dual-mode controller with disabled BR/EDR is possible or
not.
To address this issue, introduce a new setting called static-address. If
support for this setting is signaled that means that the kernel supports
using static addresses. And if used on dual-mode controllers with BR/EDR
disabled it means that a configured static address can be used.
In addition utilize the same setting for the list of current active
settings that indicates if a static address is configured and if that
address will be actually used.
With this in mind the existing Set Static Address management command
has been extended to return the current settings. That way the caller
of that command can easily determine if the programmed address will
be used or if extra steps are required.

For Secure Connections support and the usage of out-of-band pairing,
it is needed to read the P-256 hash and randomizer or P-192 hash and
randomizer. This change will read P-192 data when Secure Connections
is disabled and P-192 and P-256 data when it is enabled.
The difference is between using HCI Read Local OOB Data and using the
new HCI Read Local OOB Extended Data command. The first one has been
introduced with Bluetooth 2.1 and returns only the P-192 data.
< HCI Command: Read Local OOB Data (0x03|0x0057) plen 0
> HCI Event: Command Complete (0x0e) plen 36

Randomizer R with P-192: 9ee63b7dec411d3b467c5ae446df7f7d
The second command has been introduced with Bluetooth 4.1 and will
return P-192 and P-256 data.
< HCI Command: Read Local OOB Extended Data (0x03|0x007d) plen 0
> HCI Event: Command Complete (0x0e) plen 68
Read Local OOB Extended Data (0x03|0x007d) ncmd 1
Status: Success (0x00)
Hash C from P-192: 6489731804b156fa6355efb8124a1389
Randomizer R with P-192: 4781d5352fb215b2958222b3937b6026
Hash C from P-256: 69ef8a928b9d07fc149e630e74ecb991
Randomizer R with P-256: 4781d5352fb215b2958222b3937b6026
The change for the management interface is transparent and no change
is required for existing userspace. The Secure Connections feature
needs to be manually enabled. When it is disabled, then userspace
only gets the P-192 returned and with Secure Connections enabled,
userspace gets P-192 and P-256 in an extended structure.
It is also acceptable to just ignore the P-256 data since it is not
required to support them. The pairing with out-of-band credentials
will still succeed. However then of course no Secure Connection will
b established.

The scan interval and window parameters are used for LE passive
background scanning and connection establishment. This allows
userspace to change the values.
These two values should be kept in sync with whatever is used for
the scan parameters service on remote devices. And it puts the
controlling daemon (for example bluetoothd) in charge of setting
the values.
Main use case would be to switch between two sets of values. One
for foreground applications and one for background applications.

On dual-mode BR/EDR/LE and LE only controllers it is possible
to configure a random address. There are two types or random
addresses, one is static and the other private. Since the
random private addresses require special privacy feature to
be supported, the configuration of these two are kept separate.
This command allows for setting the static random address. It is
only supported on controllers with LE support. The static random
address is suppose to be valid for the lifetime of the controller
or at least until the next power cycle. To ensure such behavior,
setting of the address is limited to when the controller is
powered off.
The special BDADDR_ANY address (00:00:00:00:00:00) can be used to
disable the static address. This is also the default value.

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"

This patch adds a new mgmt command for enabling and disabling
LE advertising. The command depends on the LE setting being enabled
first and will return a "rejected" response otherwise. The patch also
adds safeguards so that there will ever only be one set_le or
set_advertising command pending per adapter.
The response handling and new_settings event sending is done in an
asynchronous request callback, meaning raw HCI access from user space to
enable advertising (e.g. hciconfig leadv) will not trigger the
new_settings event. This is intentional since trying to support mixed
raw HCI and mgmt access would mean adding extra state tracking or new
helper functions, essentially negating the benefit of using the
asynchronous request framework. The HCI_LE_ENABLED and HCI_LE_PERIPHERAL
flags however are updated correctly even with raw HCI access so this
will not completely break subsequent access over mgmt.

This defines two new messages, one event that will inform
userspace that a new Long Term Key was exchanged and one that
will allow userspace to load LTKs into the kernel.
Besides the information necessary for the restablishement of
the secure link, we added some extra information: "authenticated"
that informs if the key can be used to establish an authenticated
link, and "master" that informs the role in that the key should
be used.

This patch updates mgmt_ev_device_connected and mgmt_ev_device found to
include an EIR-encoded remote name and class whenever possible. With
this addition the mgmt_ev_remote_name event becomes unnecessary and can
be removed. Since the connected event doesn't map to hci_conn_complete
anymore a HCI_CONN_MGMT_CONNECTED flag is added to track when mgmt has
been notified about a connection.

This patch add a two byte eir_len parameter mgmt_ev_device_found. Since
it's unlikely that the data will in the short term be much bigger than
conventional EIR lengths just use a small stack based buffer for now to
avoid dynamic memory allocation & freeing.

This patch adds a missing confirm_name field to mgmt_ev_device_found.
Support for setting the correct value for this field is not implemented
yet, but having it part of the struct definition ensures that user-space
gets correct sized device_found events and is thereby able to do at
least rudimentary parsing of them.

Instead of having an explicit service cache command we can make the mgmt
API simpler by implicitly enabling the cache when mgmt_read_info is
called for the first time and disabling it when mgmt_set_dev_class is
called.

The management protocol uses a single byte for error codes (aka command
status). In some places this value is directly copied from HCI and in
other a POSIX error number is used. This makes it impossible for
user-space to uniquily decipher the meaning of an error.
To solve this issue a new mgmt-specific set of error codes is added
along with a conversion table for HCI status values.

The kernel needs to know whether it should connect to a device over
BR/EDR or over LE. This is particularly important in the future when
dual-mode device may be connectable also over LE. It is also important
if/when we decide to move the LE advertisement cache from the kernel
into user-space. Adding the type to the mgmt command also ensures
conformance with the latest mgmt API spec.

Add management interface events for blocking/unblocking a device.
Sender of the block device command gets cmd complete and other
mgmt sockets get the event. Event is also sent to mgmt sockets when
blocking is done with ioctl, e.g when blocking a device with
hciconfig. This makes it possible for bluetoothd to track status
of blocked devices when a third party block or unblocks a device.
Event sending is handled in mgmt_device_blocked function which gets
called from hci_blacklist_add in hci_core.c. A pending command is
added in mgmt_block_device, so that it can found when sending the
event - the event is not sent to the socket from which the pending
command came. Locks were moved out from hci_core.c to hci_sock.c
and mgmt.c, because locking is needed also for mgmt_pending_add in
mgmt.c.
