[ Upstream commit fe4840df0bdf341f376885271b7680764fe6b34e ]
If a command is received while a bonding is ongoing consider it a
pairing failure so the session is cleanup properly and the device is
disconnected immediately instead of continuing with other commands that
may result in the session to get stuck without ever completing such as
the case bellow:
> ACL Data RX: Handle 2048 flags 0x02 dlen 21
SMP: Identity Information (0x08) len 16
Identity resolving key[16]: d7e08edef97d3e62cd2331f82d8073b0
> ACL Data RX: Handle 2048 flags 0x02 dlen 21
SMP: Signing Information (0x0a) len 16
Signature key[16]: 1716c536f94e843a9aea8b13ffde477d
Bluetooth: hci0: unexpected SMP command 0x0a from XX:XX:XX:XX:XX:XX
> ACL Data RX: Handle 2048 flags 0x02 dlen 12
SMP: Identity Address Information (0x09) len 7
Address: XX:XX:XX:XX:XX:XX (Intel Corporate)
While accourding to core spec 6.1 the expected order is always BD_ADDR
first first then CSRK:
When using LE legacy pairing, the keys shall be distributed in the
following order:
LTK by the Peripheral
EDIV and Rand by the Peripheral
IRK by the Peripheral
BD_ADDR by the Peripheral
CSRK by the Peripheral
LTK by the Central
EDIV and Rand by the Central
IRK by the Central
BD_ADDR by the Central
CSRK by the Central
When using LE Secure Connections, the keys shall be distributed in the
following order:
IRK by the Peripheral
BD_ADDR by the Peripheral
CSRK by the Peripheral
IRK by the Central
BD_ADDR by the Central
CSRK by the Central
According to the Core 6.1 for commands used for key distribution "Key
Rejected" can be used:
'3.6.1. Key distribution and generation
A device may reject a distributed key by sending the Pairing Failed command
with the reason set to "Key Rejected".

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
