According to IEEE Std 802.11-2016, 9.4.2.25 when fields of an RSNE are
not included, the default values are used. The cipher suite defaults
were hardcoded to CCMP in the previous implementation, but the default
is actually different for DMG: GCMP (per 9.4.2.25.2).
It is not possible to find out from the RSNE if the network is non-DMG
or DMG, so callers of wpa_parse_wpa_ie_rsn() need to handle this case
based on context, which can be different for each caller.
In order to fix this issue, add flags to the wpa_ie_data indicating
whether pairwise/group ciphers were included in the RSNE. Callers can
check these flags and fill in the appropriate ciphers. The
wpa_parse_wpa_ie_rsn() function still initializes the ciphers to CCMP by
default so existing callers will not break. This change also fixes some
callers which need to handle the DMG network case.

The Android-specific chmod and chown operations on the client socket
(for communication with wpa_supplicant) did not protect against file
replacement between the bind() and chmod()/chown() calls. If the
directory in which the client socket is created (depends a bit on the
version and platform, but /data/misc/wifi/sockets is commonly used)
allows write access to processes that are different (less privileged)
compared to the process calling wpa_ctrl_open2(), it might be possible
to delete the socket file and replace it with something else (mainly, a
symlink) before the chmod/chown operations occur. This could have
resulted in the owner or permissions of the target of that symlink being
modified.
In general, it would be safest to use a directory which has more limited
write privileges (/data/misc/wifi/sockets normally has 'wifi' group
(AID_WIFI) with write access), but if that cannot be easily changed due
to other constraints, it is better to make wpa_ctrl_open2() less likely
to enable this type of race condition between the operations.
Replace chown() with lchown() (i.e., a version that does not dereference
symlinks) and chmod() with fchmod() on the socket before the bind() call
which is also not going to dereference a symlink (whereas chmod()
would). lchown() is a standard operation, but the fchmod() on the socket
is less so (unspecified behavior in some systems). However, it seems to
work on Linux and in particular, on Android, where this code is
executed.

This new QCA vendor command is used to query the supported AKM suite
selectors from the driver. There has been no such capability indication
from the driver and thus the current user space has to assume the driver
to support all the AKMs. This may be the case with some drivers (e.g.,
mac80211-based ones) but there are cfg80211-based drivers that implement
SME and have constraints on which AKMs can be supported (e.g., such
drivers may need an update to support SAE AKM using
NL80211_CMD_EXTERNAL_AUTH). Allow such drivers to specify the exact set
of supported AKMs so that user space tools can determine what network
profile options should be allowed to be configured. This command returns

A backhaul AP must support receiving both 3addr and 4addr frames from a
backhaul STA, so create a VLAN for it just like is done for WDS, i.e.,
by calling hostapd_set_wds_sta(). Since Multi-AP requires WPA2 (never
WEP), we can safely call hostapd_set_wds_encryption() as well and we can
reuse the entire WDS condition.

that function is meant for parsing IEs, it works for subelements.

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.

Add interface for drivers to report changes in TX/RX throughput
dynamically to user space. This information can be used by userspace
tools to tune kernel's TCP parameters in order to achieve peak
throughput. The driver may optionally provide guidance on which TCP
parameters to be configured for optimal performance along with the
values to be configured.
The TCP parameters that need to be tuned for peak performance are not
interface specific. Based on the guidance from the driver and
considering the other interfaces that may be affected with the new
configurations, a userspace tool has to choose the values to be
configured for these parameters to achieve optimal performance across
interfaces.
The throughput levels informed by the driver with this event are only
for providing guidance on TCP parameter tuning from userspace. The
driver may change the thresholds used to decide low or medium or high
throughput levels based on several parameters based on the PHY layer
capacity in the current connection, the number of packets being
dispatched per second, or the number of packets pending in queues, etc.
The throughput levels may not be consistent with the actual throughput

In the current implementation, upon an EAP method failure, followed by
an EAP failure, the EAP Status is propagated up in wpa_supplicant with a

The solution in this commit is generic to all EAP methods, and can be

its own based on having own and peer bootstrapping info. This prevented
Responder from selecting not to use mutual authentication in such a
case. Fix this by allowed Initiator to fall back to non-mutual
authentication based on Responder choice if the bootstrapping mechanism
allows this (PKEX does not; it mandates use of mutual authentication).

This was originally added to allow the IEEE 802.11 protocol to be
tested, but there are no known fully functional implementations based on
this nor any known deployments of PeerKey functionality. Furthermore,
PeerKey design in the IEEE Std 802.11-2016 standard has already been
marked as obsolete for DLS and it is being considered for complete
removal in REVmd.
This implementation did not really work, so it could not have been used
in practice. For example, key configuration was using incorrect
algorithm values (WPA_CIPHER_* instead of WPA_ALG_*) which resulted in
mapping to an invalid WPA_ALG_* value for the actual driver operation.
As such, the derived key could not have been successfully set for the
link.
Since there are bugs in this implementation and there does not seem to
be any future for the PeerKey design with DLS (TDLS being the future for
DLS), the best approach is to simply delete all this code to simplify
the EAPOL-Key handling design and to get rid of any potential issues if
these code paths were accidentially reachable.

This part is missing from IEEE Std 802.11ai-2016, but the lack of DHss
here means there would not be proper PFS for the case where PMKSA
caching is used with FILS SK+PFS authentication. This was not really the
intent of the FILS design and that issue was fixed during REVmd work
with the changes proposed in
https://mentor.ieee.org/802.11/dcn/17/11-17-0906-04-000m-fils-fixes.docx
that add DHss into FILS-Key-Data (and PTK, in practice) derivation for
the PMKSA caching case so that a unique ICK, KEK, and TK are derived

IEEE Std 802.11ai-2016 had missed a change in the Pairwise key hierarchy
clause (12.7.1.3 in IEEE Std 802.11-2016) and due to that, the previous
implementation ended up using HMAC-SHA-1 -based PMKID derivation. This
was not really the intent of the FILS design and that issue was fixed
during REVmd work with the changes proposed in
https://mentor.ieee.org/802.11/dcn/17/11-17-0906-04-000m-fils-fixes.docx
that change FILS cases to use HMAC-SHA-256 and HMAC-SHA-384 based on the
negotiated AKM.
Update the implementation to match the new design. This changes the
rsn_pmkid() function to take in the more generic AKMP identifier instead
of a boolean identifying whether SHA256 is used.
Note: This is not backwards compatible, i.e., this breaks PMKSA caching
based on the initial ERP key hierarchy setup if only STA or AP side
implementation is updated. PMKSA caching based on FILS authentication
exchange is not impacted by this, though.

IEEE 802.11 standard defines the suite selectors in <OUI>:<subtype>
format where OUI uses hexadecimal format and subtype decimal format.
These WLAN_AKM_SUITE_* definitions ended up getting written incorrectly
by interpretting the decimal part as hexadecimal and as such, by having
an incorrect value. However, the older RSN_AUTH_KEY_MGMT_* values were
defined with correct values and those definitions were used in most
locations.
This commit fixes the AKM suite selector values in RADIUS WLAN-AKM-Suite
attribute for FILS and Suite B. In addition, the AKM values used in
nl80211 driver configuration (NL80211_ATTR_AKM_SUITES) are fixed for the
Suite B cases.

Commit c79238b6a4 ('Define a QCA vendor

qca_vendor_attr_sar_limits_selections documentations and actual values.
The BDF SAR profiles are 0-based, so rename the enum values and reorder
the values keep the actual values more convenient. While this changes
values over the interface, this is justifiable since the new command was
introduced only recently and it had not been released in any driver.

Suite B 192-bit addition from IEEE Std 802.11ac-2013 replaced the
previous fixed length Key MIC field with a variable length field. That
change was addressed with an addition of a new struct defined for the
second MIC length. This is not really scalable and with FILS coming up
with a zero-length MIC case for AEAD, a more thorough change to support
variable length MIC is needed.
Remove the Key MIC and Key Data Length fields from the struct
wpa_eapol_key and find their location based on the MIC length
information (which is determined by the AKMP). This change allows the
separate struct wpa_eapol_key_192 to be removed since struct
wpa_eapol_key will now include only the fixed length fields that are
shared with all EAPOL-Key cases in IEEE Std 802.11.

Station should be able to connect initially without ft_pmk_cache filled,
so the target AP has the PSK available and thus the same information as
the origin AP. Therefore neither caching nor communication between the
APs with respect to PMK-R0 or PMK-R1 or VLANs is required if the target
AP derives the required PMKs locally.
This patch introduces the generation of the required PMKs locally for
FT-PSK. Additionally, PMK-R0 is not stored (and thus pushed) for FT-PSK.
So for FT-PSK networks, no configuration of inter-AP communication is
needed anymore when using ft_psk_generate_local=1 configuration. The
default behavior (ft_psk_generate_local=0) remains to use the pull/push
protocol.

Assign QCA vendor specific commands, attributes, and events for
supporting indoor location features.
These features include:
1. Fine timing measurement (FTM) - allows measurement of distance
between two stations. Based on IEEE P802.11-REVmc/D7.0, 11.24.6 FTM is
performed between two stations: one is an initiator, typically a client
that wants to measure distance to another AP, and one is a responder,
typically an AP which responds to measurement requests from other
clients. The responder can be configured to report its location, either
in absolute coordinates (LCI) or free-form description (LCR).
2. Angle of arrival (AOA) - allows measurement of azimuth and elevation
between two stations.
The above features can be combined to allow a station to get an accurate
indoor location.
