This increases the priority of the p2p-send-action radio work, i.e., the
radio work used for transmitting potentially offchannel P2P Action
frames by marking it as the next radio work to execute. This is to avoid
the delay in transmissions due to already queued offchannel radio work
items in the queue. In particular, this means not having to wait for a
pending p2p-scan radio work to be executed before the new P2P Action
frame can be transmitted. This helps in avoiding timeouts on the peer
device when a P2P Action frames is received during other activity on the
device.
Signed-off-by: Jouni Malinen <jouni@codeaurora.org>
The previous implementation rejects the p2p-send-action work while there
is already one in progress (wpas_send_action_cb() has already been
called for it to start operation). Enhance the same to also consider any
p2p-send-action works pending in the radio work (i.e., waiting for that
wpas_send_action_cb() call).
This is considering the current behaviour of P2P to handle the state
corresponding to respective Action frame transmission:
pending_action_state. If a new P2P Action frame transmission is queued
while there is another one already in the queue, the transmit status of
the first frame is wrongly intepreted by the P2P state machine which has
already scheduled/queued another frame for transmission.

An earlier change in drivers_ops API for struct external_auth broke the
way SSID and BSSID for an external authentication request were stored.
The implementation depended on the memory array being available in the

when only SSID and BSSID was needed. Fix this by replacing that

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 Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
backhaul STA through WPS. To enable this, the backhaul STA needs to add
a Multi-AP IE to the WFA vendor extension element in the WSC M1 message
that indicates it supports the Multi-AP backhaul STA role. The Registrar
(if it support Multi-AP onboarding) will respond to that with a WSC M8
message that also contains the Multi-AP IE, and that contains the
credentials for the backhaul SSID (which may be different from the SSID
on which WPS is performed).
Introduce a new parameter to wpas_wps_start_pbc() and allow it to be
set via control interface's new multi_ap=1 parameter of WPS_PBC call.
multi_ap_backhaul_sta is set to 1 in the automatically created SSID.
Thus, if the AP does not support Multi-AP, association will fail and
WPS will be terminated.
Only wps_pbc is supported.
This commit adds the multi_ap argument only to the control socket
interface, not to the D-Bus interface.
Since WPS associates with the fronthaul BSS instead of the backhaul BSS,
we should not drop association if the AP announces fronthaul-only BSS.
Still, we should only do that in the specific case of WPS. Therefore,
add a check to multi_ap_process_assoc_resp() to allow association with a
fronthaul-only BSS if and only if key_mgmt contains WPS.

This speeds up P2P responses to frames received on an operating channel

This addresses an issue showing up in the

Provision Discovery Request frame can be received on the operating

This reverts commit 2564184440.
Commit 2564184440 ("mesh: Apply channel attributes before setup

memory. This seems to be caused by hapd->started not getting set when
going through a callback to start hostapd operation (e.g., when using
HT40 coex scan) due to hostapd_setup_bss() not getting called. This
results in hostapd_free_hapd_data() not clearing allocated
hapd->wpa_auth. This can be reproduced with the hwsim test case
mesh_secure_ocv_mix_legacy.
A more complete cleanup of the pending mesh patch for DFS support seems
to be needed to fix this properly, so the best approach for now is to
revert this patch and bring it back once rest of the mesh changes are

Some distributions (e.g., Debian) have started introducting systemwide
OpenSSL policies to disable older protocol versions and ciphers
throughout all programs using OpenSSL. This can result in significant
number of interoperability issues with deployed EAP implementations.
Allow explicit wpa_supplicant (EAP peer) and hostapd (EAP server)
parameters to be used to request systemwide policies to be overridden if
older versions are needed to be able to interoperate with devices that
cannot be updated to support the newer protocol versions or keys. The
default behavior is not changed here, i.e., the systemwide policies will
be followed if no explicit override configuration is used. The overrides
should be used only if really needed since they can result in reduced
security.
In wpa_supplicant, tls_disable_tlsv1_?=0 value in the phase1 network
profile parameter can be used to explicitly enable TLS versions that are
disabled in the systemwide configuration. For example,
phase1="tls_disable_tlsv1_0=0 tls_disable_tlsv1_1=0" would request TLS
v1.0 and TLS v1.1 to be enabled even if the systemwide policy enforces
TLS v1.2 as the minimum version. Similarly, openssl_ciphers parameter
can be used to override systemwide policy, e.g., with
openssl_ciphers="DEFAULT@SECLEVEL=1" to drop from security level 2 to 1
in Debian to allow shorter keys to be used.
In hostapd, tls_flags parameter can be used to configure similar
options. E.g., tls_flags=[ENABLE-TLSv1.0][ENABLE-TLSv1.1]

"The /dev/random interface is considered a legacy interface, and

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

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).

After the network changed to a new channel, perform an SA Query with the
AP after a random delay if OCV was negotiated for the association. This
is used to confirm that we are still operating on the real operating
channel of the network. This commit is adding only the station side
functionality for this, i.e., the AP behavior is not changed to
disconnect stations with OCV that do not go through SA Query.

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.

The previous implementation ended up replacing all pending IEs prepared
for Association Request frame with the FT specific IEs (RSNE, MDE, FTE)

prepared for the association (e.g., Extended Capabilities, RM Enabled
Capabilities, Supported Operating Classes, vendor specific additions).
Fix this by replacing only the known FT specific IEs with the
appropriate values for FT protocol while maintaining other already

Add support for negotiating WNM Collocated Interference Reporting. This
allows hostapd to request associated STAs to report their collocated
interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.
For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".
For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".
This commit adds support for reporting changes in the collocated
interference (Automatic Report Enabled == 1 and partial 3), but not for
periodic reports (2 and other part of 3).

In case that the protocol used for association is WPA the WPA IE was
inserted before other (non vendor specific) IEs. This is not in

Explicitly set the PMF configuration to 0 (NO_MGMT_FRAME_PROTECTION) for

when the network block is configured with PMF set to required, but the

such an association.
This fixes issues with drivers that use the NL80211_ATTR_USE_MFP
attribute to set expectations for PMF use. The combination of non-RSN
connection with claimed requirement for PMF (NL80211_MFP_REQUIRED) could

If the RADIUS authentication server dropped the cached ERP keys for any
reason, FILS authentication attempts with ERP fails and the previous
wpa_supplicant implementation ended up trying to use the same keys for

Address this by trying to use full (non-FILS) authentication when trying

profile if the previous authentication attempt had failed. This allows
new ERP keys to be established and FILS authentication to be used again

The max_oper_chwidth is parsed in wpa_config_set as INT_RANGE (see
ssid_fields). The actual parsing for INT_RANGE is done by
wpa_config_parse_int which can only store the result as full integer.
max_oper_chwidth is stored as u8 (a single byte) in wpa_ssid. This means
that on little endian systems, the least significant byte of the parsed
value are really stored in the max_oper_chwidth. But on big endian
system, the only most significant byte is stored as max_oper_chwidth.
This means that 0 is always stored because the provided range doesn't
allow any other value for systems with multi-byte-wide integers.
This also means that for common systems with 4-byte-wide integers, the
remaining 3 bytes were written after the actual member of the struct.
This should not have influenced the behavior of succeeding members
because these bytes would have been part of the padding between the
members on most systems.
Increasing its size to a full int fixes the write operations outside of
the member and allows to use the max_oper_chwidth setting on big endian
systems.
