syzbot is again reporting attempt to cancel uninitialized work
at mgmt_index_removed() [1], for setting of HCI_MGMT flag from
mgmt_init_hdev() from hci_mgmt_cmd() from hci_sock_sendmsg() can
race with testing of HCI_MGMT flag from mgmt_index_removed() from
hci_sock_bind() due to lack of serialization via hci_dev_lock().
Since mgmt_init_hdev() is called with mgmt_chan_list_lock held, we can
safely split hci_dev_test_and_set_flag() into hci_dev_test_flag() and
hci_dev_set_flag(). Thus, in order to close this race, set HCI_MGMT flag
after INIT_DELAYED_WORK() completed.
This is a local fix based on mgmt_chan_list_lock. Lack of serialization
via hci_dev_lock() might be causing different race conditions somewhere
else. But a global fix based on hci_dev_lock() should deserve a future
patch.

The patch adds state bits, storage and HCI command chains for sending
and receiving Bluetooth Mesh advertising packets, and delivery to
requesting user space processes. It specifically creates 4 new MGMT
commands and 2 new MGMT events:
MGMT_OP_SET_MESH_RECEIVER - Sets passive scan parameters and a list of
AD Types which will trigger Mesh Packet Received events
MGMT_OP_MESH_READ_FEATURES - Returns information on how many outbound
Mesh packets can be simultaneously queued, and what the currently queued
handles are.
MGMT_OP_MESH_SEND - Command to queue a specific outbound Mesh packet,
with the number of times it should be sent, and the BD Addr to use.
Discrete advertisments are added to the ADV Instance list.
MGMT_OP_MESH_SEND_CANCEL - Command to cancel a prior outbound message
request.
MGMT_EV_MESH_DEVICE_FOUND - Event to deliver entire received Mesh
Advertisement packet, along with timing information.
MGMT_EV_MESH_PACKET_CMPLT - Event to indicate that an outbound packet is
no longer queued for delivery.

hci_abort_conn() is a wrapper around a number of DISCONNECT and
CREATE_CONN_CANCEL commands that was being invoked from hci_request
request queues, which are now deprecated. There are two versions:
hci_abort_conn() which can be invoked from the hci_event thread, and
hci_abort_conn_sync() which can be invoked within a hci_sync cmd chain.

syzbot is reporting attempt to cancel uninitialized work at

INIT_DELAYED_WORK() is called from mgmt_init_hdev() via chan->hdev_init()

The bluetooth code uses our bitmap infrastructure for the two bits (!)
of connection setup flags, and in the process causes odd problems when
it converts between a bitmap and just the regular values of said bits.
It's completely pointless to do things like bitmap_to_arr32() to convert
a bitmap into a u32. It shoudln't have been a bitmap in the first
place. The reason to use bitmaps is if you have arbitrary number of
bits you want to manage (not two!), or if you rely on the atomicity
guarantees of the bitmap setting and clearing.
The code could use an "atomic_t" and use "atomic_or/andnot()" to set and
clear the bit values, but considering that it then copies the bitmaps
around with "bitmap_to_arr32()" and friends, there clearly cannot be a
lot of atomicity requirements.
So just use a regular integer.
In the process, this avoids the warnings about erroneous use of
bitmap_from_u64() which were triggered on 32-bit architectures when
conversion from a u64 would access two words (and, surprise, surprise,
only one word is needed - and indeed overkill - for a 2-bit bitmap).
That was always problematic, but the compiler seems to notice it and
warn about the invalid pattern only after commit 0a97953fd221 ("lib: add
bitmap_{from,to}_arr64") changed the exact implementation details of
'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

When an Advertisement Monitor is configured with SamplingPeriod 0xFF,
the controller reports only one adv report along with the MSFT Monitor
Device event.
When an advertiser matches multiple monitors, some controllers send one
adv report for each matched monitor; whereas, some controllers send just
one adv report for all matched monitors.
In such a case, report Adv Monitor Device Found event for each matched
monitor.

A number of places in the MGMT handlers we examine the command queue for
other commands (in progress but not yet complete) that will interact
with the process being performed. However, not all commands go into the
queue if one of:
1. There is no negative side effect of consecutive or redundent commands
2. The command is entirely perform "inline".
This change examines each "pending command" check, and if it is not
needed, deletes the check. Of the remaining pending command checks, we
make sure that the command is in the pending queue by using the
mgmt_pending_add/mgmt_pending_remove pair rather than the
mgmt_pending_new/mgmt_pending_free pair.

This patch adds the support of the AOSP Bluetooth Quality Report
(BQR) events.
Multiple vendors have supported the AOSP Bluetooth Quality Report.
When a Bluetooth controller supports the capability, it can enable
the aosp capability through hci_set_aosp_capable. Then hci_core will
set up the hdev->aosp_set_quality_report callback through aosp_do_open
if the controller responds to support the quality report capability.
Note that Intel also supports a distinct telemetry quality report
specification. Intel sets up the hdev->set_quality_report callback
in the btusb driver module.

This makes hci_suspend_notifier use the hci_*_sync which can be
executed synchronously which is allowed in the suspend_notifier and
simplifies a lot of the handling since the status of each command can
be checked inline so no other work need to be scheduled thus can be
performed without using of a state machine.
