Changes made to add support for fast advertising interval
as per core 4.1 specification, section 9.3.11.2.
A peripheral device entering any of the following GAP modes and
sending either non-connectable advertising events or scannable
undirected advertising events should use adv_fast_interval2
(100ms - 150ms) for adv_fast_period(30s).
- Non-Discoverable Mode
- Non-Connectable Mode
- Limited Discoverable Mode
- General Discoverable Mode

This commit makes the kernel not send the next queued HCI command until
a command complete arrives for the last HCI command sent to the
controller. This change avoids a problem with some buggy controllers
(seen on two SKUs of QCA9377) that send an extra command complete event
for the previous command after the kernel had already sent a new HCI
command to the controller.
The problem was reproduced when starting an active scanning procedure,
where an extra command complete event arrives for the LE_SET_RANDOM_ADDR
command. When this happends the kernel ends up not processing the
command complete for the following commmand, LE_SET_SCAN_PARAM, and
ultimately behaving as if a passive scanning procedure was being
performed, when in fact controller is performing an active scanning
procedure. This makes it impossible to discover BLE devices as no device
found events are sent to userspace.
This problem is reproducible on 100% of the attempts on the affected
controllers. The extra command complete event can be seen at timestamp
27.420131 on the btmon logs bellow.

With commit e163376220 ("Bluetooth: Handle bt_accept_enqueue() socket
atomically") lock_sock[_nested]() is used to acquire the socket lock
before manipulating the socket. lock_sock[_nested]() may block, which
is problematic since bt_accept_enqueue() can be called in bottom half
context (e.g. from rfcomm_connect_ind()):
[<ffffff80080d81ec>] __might_sleep+0x4c/0x80
[<ffffff800876c7b0>] lock_sock_nested+0x24/0x58
[<ffffff8000d7c27c>] bt_accept_enqueue+0x48/0xd4 [bluetooth]
[<ffffff8000e67d8c>] rfcomm_connect_ind+0x190/0x218 [rfcomm]
Add a parameter to bt_accept_enqueue() to indicate whether the
function is called from BH context, and acquire the socket lock
with bh_lock_sock_nested() if that's the case.
Also adapt all callers of bt_accept_enqueue() to pass the new
parameter:
- l2cap_sock_new_connection_cb()
- uses lock_sock() to lock the parent socket => process context
- rfcomm_connect_ind()
- acquires the parent socket lock with bh_lock_sock() => BH
context
- __sco_chan_add()
- called from sco_chan_add(), which is called from sco_connect().
parent is NULL, hence bt_accept_enqueue() isn't called in this
code path and we can ignore it
- also called from sco_conn_ready(). uses bh_lock_sock() to acquire
the parent lock => BH context

Random address can be set only if the instance is created which
is done in Set ext adv param.
Random address and rpa expire timer and flags have been added

This introduces a hci_get_random_address() which returns the

on the instance flags and hdev flags. New function is required
since own address type should be known before setting adv params
but address can be set only after setting params.

The poll() changes were not well thought out, and completely
unexplained. They also caused a huge performance regression, because
"->poll()" was no longer a trivial file operation that just called down
to the underlying file operations, but instead did at least two indirect
calls.
Indirect calls are sadly slow now with the Spectre mitigation, but the
performance problem could at least be largely mitigated by changing the
"->get_poll_head()" operation to just have a per-file-descriptor pointer
to the poll head instead. That gets rid of one of the new indirections.
But that doesn't fix the new complexity that is completely unwarranted
for the regular case. The (undocumented) reason for the poll() changes
was some alleged AIO poll race fixing, but we don't make the common case
slower and more complex for some uncommon special case, so this all
really needs way more explanations and most likely a fundamental
redesign.

In case of using BT_ERR and BT_INFO, convert to bt_dev_err and
bt_dev_info when possible. This allows for controller specific
reporting.

This patch increases the connection timeout for LE connections that are
triggered by the advertising report to 4 seconds.
It has been observed that devices equipped with wifi+bt combo SoC fail
to create a connection with BLE devices due to their coexistence issues.
Increasing this timeout gives them enough time to complete the
connection with success.

If the LE Set Default PHY command is supported, the indicate to the
controller that the host has no preferences for transmitter PHY or
receiver PHY selection.
Issuing this command gives the controller a clear indication that other
PHY can be selected if available.
