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
paired is a pre-requisite. Using it e.g. for the mgmt_pair_device
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.

The current management interface only allows to provide the remote
OOB input of P-192 data. This extends the command to also accept
P-256 data as well. To make this backwards compatible, the userspace
can decide to only provide P-192 data or the combined P-192 and P-256
data. It is also allowed to leave the P-192 data empty if userspace
only has the remote P-256 data.

When Secure Connections has been enabled it is possible to provide P-192
and/or P-256 data during the pairing process. The internal out-of-band
credentials storage has been extended to also hold P-256 data.
Initially the P-256 data will be empty and with Secure Connections enabled
no P-256 data will be provided. This is according to the specification
since it might be possible that the remote side did not provide either
of the out-of-band credentials.

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 support for Secure Connections need to be explicitly enabled by
userspace. This is required since only userspace that can handle the
new link key types should enable support for Secure Connections.
This command handling is similar to how Secure Simple Pairing enabling
is done. It also tracks the case when Secure Connections support is
enabled via raw HCI commands. This makes sure that the host features
page is updated as well.

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 4e6cbfd09c66 in July 2010), but then removed years later
(by Stanislaw in commit 30c97120c6c7 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.

The "new" fragmentation code (since my rewrite almost 5 years ago)
erroneously sets skb->len rather than using skb_trim() to adjust
the length of the first fragment after copying out all the others.
This leaves the skb tail pointer pointing to after where the data
originally ended, and thus causes the encryption MIC to be written
at that point, rather than where it belongs: immediately after the
data.
The impact of this is that if software encryption is done, then
a) encryption doesn't work for the first fragment, the connection
becomes unusable as the first fragment will never be properly
verified at the receiver, the MIC is practically guaranteed to
be wrong
b) we leak up to 8 bytes of plaintext (!) of the packet out into
the air
This is only mitigated by the fact that many devices are capable
of doing encryption in hardware, in which case this can't happen
as the tail pointer is irrelevant in that case. Additionally,
fragmentation is not used very frequently and would normally have
to be configured manually.
Fix this by using skb_trim() properly.

Currently, when a station leaves an IBSS network, the
corresponding BSS is not dropped from cfg80211 if there are
other active stations in the network. But, the small
window that is present when trying to determine a station's
status based on IEEE80211_IBSS_MERGE_INTERVAL introduces
a race.
Instead of trying to keep the BSS, always remove it when
leaving an IBSS network. There is not much benefit to retain
the BSS entry since it will be added with a subsequent join
operation.
This fixes an issue where a dangling BSS entry causes ath9k
to wait for a beacon indefinitely.

Due to the previous commit, when a scan finishes, it is in theory
possible to hit the following sequence:
1. interface starts being removed
2. scan is cancelled by driver and cfg80211 is notified
3. scan done work is scheduled
4. interface is removed completely, rdev->scan_req is freed,
event sent to userspace but scan done work remains pending
5. new scan is requested on another virtual interface
6. scan done work runs, freeing the still-running scan
To fix this situation, hang on to the scan done message and block
new scans while that is the case, and only send the message from
the work function, regardless of whether the scan_req is already
freed from interface removal. This makes step 5 above impossible
and changes step 6 to be
5. scan done work runs, sending the scan done message
As this can't work for wext, so we send the message immediately,
but this shouldn't be an issue since we still return -EBUSY.

When an interface/wdev is removed, any ongoing scan should be
cancelled by the driver. This will make it call cfg80211, which
only queues a work struct. If interface/wdev removal is quick
enough, this can leave the scan request pending and processed
only after the interface is gone, causing a use-after-free.
Fix this by making sure the scan request is not pending after
the interface is destroyed. We can't flush or cancel the work
item due to locking concerns, but when it'll run it shouldn't
find anything to do. This leaves a potential issue, if a new
scan gets requested before the work runs, it prematurely stops
the running scan, potentially causing another crash. I'll fix
that in the next patch.
This was particularly observed with P2P_DEVICE wdevs, likely
because freeing them is quicker than freeing netdevs.

We don't set here the VHT_KNOWN / MCS_HAVE flag because not
all the low level drivers will know how to properly flag
the frames, hence the low level driver will be in charge
of setting IEEE80211_RADIOTAP_MCS_HAVE_FEC,
IEEE80211_RADIOTAP_MCS_HAVE_STBC and / or
IEEE80211_RADIOTAP_VHT_KNOWN_STBC according to its
capabilities.

ieee80211_rx_status.flags is full. Define a new vht_flag
variable to be able to set more VHT related flags and make
room in flags.

The purpose of this housekeeping is to make some room for
VHT flags. The radiotap vendor fields weren't in use.

In association request frames, there may be IEs passed from
userspace (such as interworking IEs) between HT and VHT, so
add code to insert those inbetween them.

In probe request frames, the VHT IEs should come before any
vendor IEs, but after interworking and similar, so add code
to order them correctly wrt. the IEs passed from userspace.
