ecef0687dc RRM: Support for Last Beacon Report Indication subelement
IEEE P802.11-REVmd/D2.0, 9.4.2.20.7 (Beacon request) and 9.4.2.21.7
(Beacon report) add the Last Beacon Report Indication subelement to
Beacon Request and Beacon Report elements.

Add the Last Beacon Report Indication subelement to all Beacon Report
elements if the Beacon Request indicated that this subelement is
requested.

3ec118780a RRM: Add support for beacon report fragmentation
When the frame body subelement would cause the measurement report
element to exceed the maximum element size, the frame body subelement
used to be truncated. In addition, some elements were always truncated
in order to keep the reported frame body short (e.g. RSN IE).

Alternatively, IEEE P802.11-REVmd/D2.0, 9.4.2.21.7 extension to Beacon
reporting can be used: The frame body subelement is fragmented across
multiple beacon report elements, and the reported frame body fragment ID
subelement is added.

Use beacon report fragmentation instead of truncating the frame body
as this method gives the AP a more complete information about the
reported APs.

89a7cdd690 crypto: Add option to use getrandom()
According to random(4) manual, /dev/random is essentially deprecated on
Linux for quite some time:

"The /dev/random interface is considered a legacy interface, and
/dev/urandom is preferred and sufficient in all use cases, with the
exception of applications which require randomness during early boot
time; for these applications, getrandom(2) must be used instead, because
it will block until the entropy pool is initialized."

An attempt to use it would cause unnecessary blocking on machines
without a good hwrng even when it shouldn't be needed. Since Linux 3.17,
a getrandom(2) call is available that will block only until the
randomness pool has been seeded.

It is probably not a good default yet as it requires a fairly recent
kernel and glibc (3.17 and 2.25 respectively).

19677b77c3 OCE: Add RSSI based association rejection support (STA)
An AP might refuse to connect a STA if it has a low RSSI. In such case,
the AP informs the STA with the desired RSSI delta and a retry timeout.
Any subsequent association attempt with that AP (BSS) should be avoided,
unless the RSSI level improved by the desired delta or the timeout has
expired.

dc9b7d217c P2P: Set global->p2p_group_formation in wpas_p2p_join_start() for p2pdev
When a dedicated P2P device interface is used, the
global->p2p_group_formation was not set in wpas_p2p_join_start() if no
separate group interface is used. This would cause that in case of a
failure in group formation, the cleaning of p2p_in_provisioning is done
on the wrong interface. Furthermore, P2P_CANCEL command could not be
used to stop such a group-join operation. Fix this by setting the
global->p2p_group_formation correctly in case that the group interface
is reusing wpa_s->parent.

feature. Note that according to IEEE Std 802.1X-2010 replay protection

protection is something that KaY can use to manage SecY state.

2fc0675683 mka: Fix lowest acceptable Packet Number (LPN) calculation and use
The purpose of the Lowest Acceptable PN (lpn) parameters in the MACsec
SAK Use parameter set is to enforce delay protection. Per IEEE Std
802.1X-2010, Clause 9, "Each SecY uses MKA to communicate the lowest PN
used for transmission with the SAK within the last two seconds, allowing
receivers to bound transmission delays."

When encoding the SAK Use parameter set the KaY should set llpn and olpn
to the lowest PN transmitted by the latest SAK and oldest SAK (if
active) within the last two seconds. Because MKPDUs are transmitted
every 2 seconds (MKA_HELLO_TIME), the solution implemented here
calculates lpn based on the txsc->next_pn read during the previous MKPDU
transmit.

Upon receiving and decoding a SAK Use parameter set with delay
protection enabled, the KaY will update the SecY's lpn if the delay
protect lpn is greater than the SecY's current lpn (which is a product
of last PN received and replay protection and window size).

b678ed1efc macsec: Make pre-shared CKN variable length
IEEE Std 802.1X-2010, 9.3.1 defines following restrictions for CKN:

"MKA places no restriction on the format of the CKN, save that it comprise
an integral number of octets, between 1 and 32 (inclusive), and that all
potential members of the CA use the same CKN. No further constraints are
placed on the CKNs used with PSKs, ..."

Hence do not require a 32 octet long CKN but instead allow a shorter CKN
to be configured.

This fixes interoperability with some Aruba switches, that do not accept
a 32 octet long CKN (only support shorter ones).

Advertise vendor specific Multi-AP IE in (Re)Association Request frames
and process Multi-AP IE from (Re)Association Response frames if the user
enables Multi-AP fuctionality. If the (Re)Association Response frame

Enable 4-address mode after association (if the Association Response
frame contains the Multi-AP IE). Also enable the bridge in that case.
This is necessary because wpa_supplicant only enables the bridge in
wpa_drv_if_add(), which only gets called when an interface is added
through the control interface, not when it is configured from the

f9da7505bf OCV: Include and verify OCI in SA Query frames
Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.

On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.

Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.

As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.
