This commit adds an macro to allow UUID 128
to be written in more user-friendly form.
UUID in 128 bit form requires an array creation.
To complicate the whole thing - it requires the array to start from LSB,
so using the readable form, we have to write it down backwards.
Old way to declare example UUID 6E400001-B5A3-F393-E0A9-E50E24DCCA9E:
0x9E, 0xCA, 0xDC, 0x24, 0x0E, 0xE5, 0xA9, 0xE0,
0x93, 0xF3, 0xA3, 0xB5, 0x01, 0x00, 0x40, 0x6E
A form provided by this commit:

Add public API function in GATT to check if a specific connection has
subscribed to the given attribute.
Without this function the application has to keep track of which
connections has subscribed using the callbacks from BT_GATT_CCC_MANAGED
since the cfg_changed callback of the CCC doesn't carry connection
context.
The other alternative is for the application to parse the information
in the struct _bt_gatt_ccc object. Although this object has structure
information available to the application the structure is marked as
internal, so the application shouldn't rely on this definition.

In addition to that also ensure that notification are not re-enabled
until the proper security level is reached to conform to the following
statement:
'10.3.1.1 Handling of GATT indications and notifications
A client “requests” a server to send indications and notifications
by appropriately configuring the server via a Client Characteristic
Configuration Descriptor. Since the configuration is persistent
across a disconnection and reconnection, security requirements must
be checked against the configuration upon a reconnection before
sending indications or notifications. When a server reconnects to a
client to send an indication or notification for which security is
required, the server shall initiate or request encryption with the
client prior to sending an indication or notification. If the client
does not have an LTK indicating that the client has lost the bond,
enabling encryption will fail.'

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.

deadlocks in some cases.

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
anyway quite minimal.

Each connection related callback function will have to loop for all

pointer. This is inefficient if there are many callback activations
during the connection.

This adds a int return to recv callback which can be used to notify the

can return -EINPROGRESS to inform the stack the data will be processed
asynchronously which can be complete by calling

Since BT_GATT_CHARACTERISTIC now expands to 2 attributes it may be
confusing to use bt_gatt_notify as that expects the Value attribute to
be given which is no longer visible, so this enables the user to use
the Characteristic attribute in addition to its value.

The adv_send() function was incorrectly decoding the 5-bit value (it
was using it directly as milliseconds), which effectively lead to the
code always picking the controller's minimum supported interval.
Fix this issue, but do it by simplifying the (re)transmission state
tracking so that the state is always stored in the original "packed"
8-bit value, where 5 bits are reserved for the interval, and 3 for the
count.
Fixes#7972
Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
The change changes the type of the attribute count in the
bt_gatt_service struct to size_t.
The background for the change is that with this variable being a
u16_t, we assign something that has been cast to an unsigned long
(from "ARRAY_SIZE") to an u16_t variable, and that Lint complains
about a loss of information (27 bits to 16 bits in the case I found).
(The issue seems to be not only about the cast, but about what is
casted. I suspect that Lint may be confused by the magic of
ZERO_OR_COMPILE_ERROR.)

The Bluetooth core specification splits the valid LE L2CAP PSM range
into two subranges:
- Standard, SIG-assigned fixed PSM values in the range 0x0001-0x007f
- Dynamic, allocated at runtime in the range 0x0080-0x00ff
Previously the bt_l2cap_server_register() API was assuming that the
app would always decide the PSM, which effectively made it impossible
to have collision-free dynamic PSMs. This patch extends the
implementation so that if server->psm is 0, then the stack will look
for a free PSM from the dynamic range and take it into use.
