The security level 4 is a new strong security requirement that is based
around 128-bit equivalent strength for link and encryption keys required
using FIPS approved algorithms. Which means that E0, SAFER+ and P-192
are not allowed. Only connections created with P-256 resulting from
using Secure Connections support are allowed.
This security level needs to be enforced when Secure Connection Only
mode is enabled for a controller or a service requires FIPS compliant
strong security. Currently it is not possible to enable either of
these two cases. This patch just puts in the foundation for being
able to handle security level 4 in the future.
It should be noted that devices or services with security level 4
requirement can only communicate using Bluetooth 4.1 controllers
with support for Secure Connections. There is no backward compatibilty
if used with older hardware.

The NOT_PAIRED status is only really suitable for operations where being

command seems unintuitive. In the case that either the local or the
remote user responds with a negative PIN Code response the "PIN or Key
Missing" HCI status will be generated. This patch changes the mapping of
this status from the NOT_PAIRED mgmt status to the more intuitive
AUTH_FAILED mgmt status.

When Secure Connections has been enabled it is possible to provide P-192

Initially the P-256 data will be empty and with Secure Connections enabled

The Bluetooth 4.1 specification with Secure Connections support has
just been released and controllers with this feature are still in
an early stage.
A handful of controllers have already support for it, but they do
not always identify this feature correctly. This debugfs entry
allows to tell the kernel that the controller can be treated as
it would fully support Secure Connections.
Using debugfs to force Secure Connections support of course does
not make this feature magically appear in all controllers. This
is a debug functionality for early adopters. Once the majority
of controllers matures this quirk will be removed.

For Secure Connections support and the usage of out-of-band pairing,
it is needed to read the P-256 hash and randomizer or P-192 hash and
randomizer. This change will read P-192 data when Secure Connections
is disabled and P-192 and P-256 data when it is enabled.
The difference is between using HCI Read Local OOB Data and using the
new HCI Read Local OOB Extended Data command. The first one has been
introduced with Bluetooth 2.1 and returns only the P-192 data.
< HCI Command: Read Local OOB Data (0x03|0x0057) plen 0
> HCI Event: Command Complete (0x0e) plen 36
Read Local OOB Data (0x03|0x0057) ncmd 1
Status: Success (0x00)
Hash C from P-192: 975a59baa1c4eee391477cb410b23e6d
Randomizer R with P-192: 9ee63b7dec411d3b467c5ae446df7f7d
The second command has been introduced with Bluetooth 4.1 and will
return P-192 and P-256 data.
< HCI Command: Read Local OOB Extended Data (0x03|0x007d) plen 0
> HCI Event: Command Complete (0x0e) plen 68
Read Local OOB Extended Data (0x03|0x007d) ncmd 1
Status: Success (0x00)
Hash C from P-192: 6489731804b156fa6355efb8124a1389
Randomizer R with P-192: 4781d5352fb215b2958222b3937b6026
Hash C from P-256: 69ef8a928b9d07fc149e630e74ecb991
Randomizer R with P-256: 4781d5352fb215b2958222b3937b6026
The change for the management interface is transparent and no change
is required for existing userspace. The Secure Connections feature
needs to be manually enabled. When it is disabled, then userspace
only gets the P-192 returned and with Secure Connections enabled,
userspace gets P-192 and P-256 in an extended structure.
It is also acceptable to just ignore the P-256 data since it is not
required to support them. The pairing with out-of-band credentials
will still succeed. However then of course no Secure Connection will
b established.

The check for HIGH security level dates back to pre-mgmt times when a
raw L2CAP socket with HIGH security level was used to trigger dedicated
bonding. For legacy pairing checking for the security level was the only
way to catch the need to authenticate in all scenarios. With mgmt
however, the pair_device command does not use HIGH security but MEDIUM
security. Therefore, the existing code would never trigger
authentication for a non-SSP connection without an MITM requirement
(e.g. if user space provided a NoInputNoOutput IO capability). In such a
scenario the mgmt_pair_device command would return success without
actually triggering any kind of pairing.
This patch updates the authentication requirement check to also consider
MEDIUM security level, and thereby ensures that mgmt_pair_device will
always trigger authentication.

NAPI was originally added to mac80211 a long time ago (by John in
commit 4e6cbfd09c in July 2010), but then removed years later
(by Stanislaw in commit 30c97120c6 in February 2013). No driver
ever used it, so that was fine.
Now I'm adding support for NAPI to our driver, so add some code
to mac80211 again to support NAPI. John was originally wrapping
some (but not nearly all NAPI-related functions), but that doesn't
scale very well with the number of functions that are there, some
of which are even only inlines. Thus, instead of doing that, let
the drivers manage the NAPI struct, except for napi_add() which is
needed so mac80211 knows how to call napi_gro_receive().
Also remove some no longer needed definitions that were left when
NAPI support was removed.
