Now that the TX callbacks happen from the system workqueue but fixed

To fix the issue store the completed TX packet information in a

callback, which will simply do nothing for this list if bt_recv()
already took care of it.

Now that the TX path and TX context (bt_conn_tx) has been redesigned
to free the contexts always in the system workqueue, it means the
system workqueue is the only context where their allocation may also
fail. This is particularly problematic with us having all L2CAP
channels (fixed & CoC alike) deferred to the system workqueue. It is
especially bad for fixed channels where being able to send responses
for SM, L2CAP signaling and ATT is critical to avoid timeouts for the
connection.
This patch moves the processing of all fixed L2CAP channels back to
the RX thread, thereby making it possible (and safe) to block while
waiting for a TX context to become available.

This is a moderate redesign of the pending TX packet handling that
aims to eliminate potential deadlocks between the TX thread and the
system workqueue thread. The main changes are:
- TX context (bt_conn_tx) is allocated during buffer allocation, i.e.
not in the TX thread.
- We don't allocate a TX context unless there's an associated
callback. When there's no callback simple integer counters are used
for tracking.
- The TX thread is no longer responsible for TX callbacks or
scheduling of TX callbacks. Instead, the callbacks get directly
scheduled (k_work_submit) from the RX priority thread.
- CONFIG_BT_CONN_TX_MAX defaults to CONFIG_BT_L2CAP_TX_BUF_COUNT,
and in most cases wont need changing. The value now only indicates
how many pending packets with a callback are possible.

The BT_HCI_TX_STACK_SIZE is carefully calculated from other
options. When those options change, e.g. from a menuconfig update, it
is important that the stack size is re-calculated, but it is not when
there is a prompt.
Therefore, make the prompt conditional such that the previously set
value is only used when it has been explicitly configured to be so.
Now users can still change the value through menuconfig and prj.conf,
by also enabling <option>_WITH_PROMPT, but when the value is
calculated by the defaults, it will continue to be calculated by
defaults instead of inheriting the intial value.
This is AFAIK a novel approach, but testing has shown that it gives
the users the behaviour they want, at the cost of some boilerplate of
course. This pattern can be applied to other options if it proves to
work as intended.
Alternatively one could remove the prompt, but then it would no longer
be possible to override the value through menuconfig.

Properties on choices work exactly the same syntactically as

- Indent help texts with a tab followed by two spaces
- Put a space between 'config' and the symbol name, not a tab. This
also helps when grepping for definitions.
- Do '# A comment' instead of '#A comment'

Key overwrite feature allows to overwrite old pairing key

Oldest keys are determined by minimum value of up-counting aging
counter. If you set CONFIG_BT_KEYS_SAVE_AGING_COUNTER_ON_PAIRING=y
aging counter values will be updated each time the secure connection
is established. This might increase flash wear out if at least two

Since bt_l2cap_create_pdu can return NULL when used under syswq context

A security vulnerability in the Bluetooth BR/EDR Bluetooth Core
specification versions 1.0 through 5.1 has been identified as
CVE-2019-9506. The Bluetooth BR/EDR encryption key negotiation
protocol is vulnerable to packet injection that could allow an
unauthenticated user to decrease the size of the entropy of the
encryption key, potentially causing information disclosure and/or
escalation of privileges via adjacent access. There is not currently
any knowledge of this being exploited.
From Core spec erratum 11838:
A device shall enforce an encryption key with at least 128-bit
equivalent strength for all services that require Security Mode 4,
Level 4. For all other services that require encryption, a device
should enforce an encryption key with at least 56-bit equivalent
strength, irrespective of whether the remote device supports Secure
Simple Pairing.
After encryption has been enabled, the Host should check the
encryption key size using either the HCI_Read_Encryption_Key_Size
command (see [Vol 2] Part E, Section 7.5.7) or a vendor-specific
method.

The storage for the public key is pub_key in hci_core.c.
When the public key event is generated the public key is copied into
this buffer, but the pointer to the event storage of the key is given
in the public key ready callback (bt_smp_pkey_ready).
SMP expects that it is safe to assign a global pointer to this variable.
In smp_init bt_pub_key_get is used to get the pointer to the public key.
In both cases SMP assigns the le_sc_pub_key to the pointer given.
This creates an issue when bt_smp_pkey_ready callback occurs after
smp_init during pairing procedure, SMP will then have a pointer to an
event buffer that has been released and contains invalid data.

Introduce a separate buffer pool for events which the HCI driver
considers discardable. Examples of such events could be e.g.

if there is a heavy inflow of such events it will not cause the
allocation for other critical events to block and may even eliminate
deadlocks in some cases.

This event is a priority one, so it's not safe to have it use the RX
buffer pool which may be depleted due to non-priority events (e.g.

safe to have a single-buffer pool for it. Also introduce a new
bt_buf_get_evt() API for HCI drivers to simplify the driver-side code,

This API had several issues:
- The parameter types and order were inconsistent with e.g.
bt_le_adv_start()
- There were no real users of num_params, which just caused increased
code size and memory consumption for no good reason.
- The error handling policy was arbitrary: if one of the
notifications would fail it would be impossible for the caller to
know if some notifications succeeded, i.e. at what point the
failure happened. Some callers might also want to make note of the
failure but continue trying to notify for the remaining parameters.
The first issue is easily fixable, but because of the other two I
think it's best we don't have this code as part of the stack, rather
require whoever needs it to do the for loop themselves. It's just a
few lines of code, so the benefit of having this in the stack was

When starting a second Friendship establishment processes the `sent_req`
field of the `lpn` struct was left set to `TRANS_CTL_OP_FRIEND_POLL`.
This prevented the initial Friend Poll being sent out on the second
attempt. Since the Friend Poll was not sent, no timeout is set and
nothing happens ever again. No more Friendship Requests are sent.
This commit clears `sent_req` back to zero when no Friend Update
response has been received after the initial Friend Poll.

This convenience macro wraps Z_DECL_ALIGN() and __in_section() to
simplify static definitions of structure instances gathered in dedicated
sections. Most of the time those go together, and the section name is
already closely related to the struct type, so abstracting things behind
a simpler interface reduces probability of mistakes and makes the code
clearer. A few input section names have been adjusted accordingly.

When removing a service using bt_gatt_service_unregister, its attributes
handles will keep their value which can cause a problem when adding the
service again to the GATT database.
When re-adding, the gatt_register routine is taking the last handle of
the GATT database to compare it with the handles of the service to be
added.
If a service has handles with a lower value than the last handle of
the database an error will occur.
If we add/remove/add the last service, no error will occur as its
handles are always greater than the last one of the database.
Instead of resetting the handles when unregistering a service and
reassign new ones we make sure that the handles of the services are
not in use in the GATT database in order to place the service back
where it used to be.

The default values for the timeouts, as well as non-defaults in most
Mesh samples, use a higher value for the RPL than then generic mesh
storage timeout. This hasn't had any effect in practice since the code
only uses the RPL timeout if it is *smaller* than the generic one.
The original intention of the code was to use the RPL timeout,
regardless of what the generic one is, whenever the RPL is the only
thing that needs updating. Add some helper macros to track the various
groups of pending flags, and perform the appropriate checks to apply
the RPL timeout whenever it's smaller than the generic timeout, or if
there are no other items to store besides the RPL.
