hostapd: add Multi-AP patches and config options
Cherry-pick Multi-AP commits from uptream: 9c06f0f6a hostapd: Add Multi-AP protocol support 5abc7823b wpa_supplicant: Add Multi-AP backhaul STA support a1debd338 tests: Refactor test_multi_ap bfcdac1c8 Multi-AP: Don't reject backhaul STA on fronthaul BSS cb3c156e7 tests: Update multi_ap_fronthaul_on_ap to match implementation 56a2d788f WPS: Add multi_ap_subelem to wps_build_wfa_ext() 83ebf5586 wpa_supplicant: Support Multi-AP backhaul STA onboarding with WPS 66819b07b hostapd: Support Multi-AP backhaul STA onboarding with WPS 8682f384c hostapd: Add README-MULTI-AP b1daf498a tests: Multi-AP WPS provisioning Add support for Multi-AP to the UCI configuration. Every wifi-iface gets an option 'multi_ap'. For APs, its value can be 0 (multi-AP support disabled), 1 (backhaul AP), 2 (fronthaul AP), or 3 (fronthaul + backhaul AP). For STAs, it can be 0 (not a backhaul STA) or 1 (backhaul STA, can only associate with backhaul AP). Also add new optional parameter to wps_start ubus call of wpa_supplicant to indicate that a Multi-AP backhaul link is required.

+From: Venkateswara Naralasetty <vnaralas@codeaurora.org>
+Date: Wed, 5 Dec 2018 11:23:51 +0100
+Subject: [PATCH] hostapd: Add Multi-AP protocol support
+
+The purpose of Multi-AP specification is to enable inter-operability
+across Wi-Fi access points (APs) from different vendors.
+
+This patch introduces one new configuration parameter 'multi_ap' to
+enable Multi-AP functionality and to configure the BSS as a backhaul
+and/or fronthaul BSS.
+
+Advertise vendor specific Multi-AP capabilities in (Re)Association
+Response frame, if Multi-AP functionality is enabled through the
+configuration parameter.
+
+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.
+
+To parse the Multi-AP Extension subelement, we use get_ie(): even though
+that function is meant for parsing IEs, it works for subelements.

+Subject: [PATCH] wpa_supplicant: Add Multi-AP backhaul STA support
+
+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
+does not contain the Multi-AP IE, disassociate.
+
+This adds a new configuration parameter 'multi_ap_backhaul_sta' to
+enable/disable Multi-AP functionality.
+
+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
+command line.

+Subject: [PATCH] multi_ap: don't reject backhaul STA on fronhaul BSS
+
+The Multi-AP specification only specifies that information elements have
+to be added to the association requests and responses; it doesn't
+specify anything about what should be done in case they are missing.
+Currently, we reject non-backhaul associations on a backhaul-only BSS,
+and non-fronthaul associations on a fronthaul-only BSS.
+
+However, this makes WPS fail when fronthaul and backhaul are separate
+SSIDs. Indeed, WPS for the backhaul link is performed on the *fronthaul*
+SSID. Thus, the association request used for WPS *will* contain the
+Multi-AP IE indicating a backhaul STA. Rejecting that association makes
+WPS fail.
+
+Therefore, accept a multi-AP backhaul STA association request on a
+fronthaul-only BSS. Still issue a warning about it, but only at level
+DEBUG intead of INFO. Also change the condition checking to make it
+clearer.
+
+While we're at it, also fix the handling of unexpected bits in the
+Multi-AP IE. 4 bits are reserved in the specification, so these
+certainly have to be ignored. The specification also doesn't say that
+setting one of the other bits is not allowed. Therefore, only report
+unexpected values in the Multi-AP IE, don't reject because of it.
+Note that a malformed IE (containing more than one byte) still triggers
+a rejection.

+Subject: [PATCH] WPS: wps_build_wfa_ext(): add multi_ap_subelem parameter
+
+The Multi-AP specification adds a new subelement to the WFA extension
+element in the WPS exchange. Add an additional parameter to
+wps_build_wfa_ext() to add this subelement. The subelement is only added
+if the parameter is non-0. Note that we don't reuse the existing
+MULTI_AP_SUB_ELEM_TYPE definition here, but rather define a new
+WFA_ELEM_MULTI_AP, to make sure the enum of WFA subelement types remains
+complete.
+
+For now, all callers set the multi_ap_subelem parameter to 0.

+Subject: [PATCH] wpa_supplicant: support Multi-AP backhaul STA onboarding
+
+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.
+
+The multi_ap argument is only added to the socket interface, not to the
+dbus interface.

+Subject: [PATCH] hostapd: support Multi-AP backhaul STA onboarding
+
+The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
+backhaul STA through WPS. To enable this, the WPS registrar offers a
+different set of credentials (backhaul credentials instead of fronthaul
+credentials) when the Multi-AP subelement is present in the WFA vendor
+extension element of the WSC M1 message.
+
+Add 3 new configuration options to specify the backhaul credentials for
+the hostapd internal registrar: multi_ap_backhaul_ssid,
+multi_ap_backhaul_wpa_psk, multi_ap_backhaul_wpa_passphrase. These are
+only relevant for a fronthaul SSID, i.e. where multi_ap is set to 2 or
+3. When these options are set, pass the backhaul credentials instead of
+the normal credentials when the Multi-AP subelement is present.
+
+Ignore the Multi-AP subelement if the backhaul config options are not
+set. Note that for an SSID which is fronthaul and backhaul at the same
+time (i.e., multi_ap == 3), this results in the correct credentials
+being sent anyway.
+
+The security to be used for the backaul BSS is fixed to WPA2PSK. The
+Multi-AP Specification only allows Open and WPA2PSK networks to be
+configured. Although not stated explicitly, the backhaul link is
+intended to be always encrypted, hence WPA2PSK.
+
+To build the credentials, the credential-building code is essentially
+copied and simplified. Indeed, the backhaul credentials are always
+WPA2PSK and never use per-device PSK. All the options set for the
+fronthaul BSS WPS are simply ignored.

++hostapd, wpa_supplicant and the Multi-AP Specification
++======================================================
++
++This document describes how hostapd and wpa_supplicant can be configured to
++support the Multi-AP Specification.
++
++Introduction to Multi-AP
++------------------------
++
++The Wi-Fi Alliance Multi-AP Specification is the technical specification for
++Wi-Fi CERTIFIED EasyMesh(TM) [1], the Wi-Fi AllianceĀ® certification program for
++Multi-AP. It defines control protocols between Wi-FiĀ® access points (APs) to
++join them into a network with centralized control and operation. It is targeted
++only at routers (repeaters, gateways, ...), not at clients. Clients are not
++involved at all in the protocols.
++
++Most of the Multi-AP specification falls outside of the scope of
++hostapd/wpa_supplicant. hostapd/wpa_supplicant is only involved for the items
++summarized below. The rest of the protocol must be implemented by a separate
++daemon, e.g. prplMesh [2]. That daemon also needs to communicate with hostapd,
++e.g. to get a list of associated clients, but this can be done using the normal
++hostapd interfaces.
++
++hostapd/wpa_supplicant needs to be configured specifically to support:
++- the WPS onboarding process;
++- configuring backhaul links.
++
++The text below refers to "Multi-AP Specification v1.0" [3].
++
++
++Fronthaul and backhaul links
++----------------------------
++
++In a Multi-AP network, the central controller can configure the SSIDs on the
++devices that are joined into the network. These are called fronthaul SSIDs.
++From the point of view of hostapd, there is nothing special about these
++fronthaul SSIDs.
++
++In addition to fronthaul SSIDs, the controller can also configure backhaul
++links. A backhaul link is a link between two access point devices, giving
++internet access to access point devices that don't have a wired link. The
++Multi-AP specification doesn't dictate this, but typically the backhaul link
++will be bridged into a LAN together with (one of) the fronthaul SSID(s) and the
++wired Ethernet ports.
++
++A backhaul link must be treated specially by hostapd and wpa_supplicant. One
++side of the backhaul link is configured through the Multi-AP protocol as the
++"backhaul STA", i.e. the client side of the link. A backhaul STA is like any
++station and is handled appropriately by wpa_supplicant, but two additional
++features are required. It must send an additional information element in each
++(Re-)Association Request ([3], section 5.2, paragraph 4). In addition, it must
++use 4-address mode for all frames sent over this link ([3], section 14).
++Therefore, wpa_supplicant must be configured explicitly as the backhaul STA
++role, by setting 'multi_ap_backhaul_sta=1' in the network configuration block
++or when configuring the SSID through the client socket. When
++'multi_ap_backhaul_sta=1', wpa_supplicant includes the Multi-AP IE in
++(Re-)Association Request messages and verifies that it is included in the
++(Re-)Association Response. If it is not, association fails. If it is,
++wpa_supplicant sets 4-address mode for this interface through a driver
++callback.
++
++The AP side of the backhaul link is called a "backhaul SSID". Such an SSID must
++be handled specially by hostapd, because it must add an additional information
++element in each (Re-)Association Response, but only to stations that have
++identified themselves as backhaul stations ([3], section 5.2, paragraph 5-6).
++This is important because it is possible to use the same BSS and SSID for
++fronthaul and backhaul at the same time. The additional information element must
++only be used for frames sent to a backhaul STA, not to a normal STA. Also,
++frames sent to a backhaul STA must use 4-address mode, while frames sent to a
++normal STA (fronthaul, when it's a fronthaul and backhaul SSID) must use
++3-address mode.
++
++An SSID is configured in Multi-AP mode in hostapd by setting the 'multi_ap'
++configuration option to 1 (backhaul SSID), 2 (fronthaul SSID) or 3
++(simultaneous backhaul and fronthaul SSID). If this option is set, hostapd
++parses the Multi-AP information element in the Association Request. If the
++station is a backhaul STA and the SSID is configured as a backhaul SSID,
++hostapd sets up 4-address mode. Since there may be multiple stations connected
++simultaneously, and each of them has a different RA (receiver address), a VLAN
++is created for each backhaul STA and it is automatically added to a bridge.
++This is the same behavior as for WDS, and the relevant option ('bridge' or
++'wds_bridge') applies here as well.
++
++If 'multi_ap' is 1 (backhaul SSID only), any station that tries to associate
++without the Multi-AP information element will be denied.
++
++If 'multi_ap' is 2 (fronthaul SSID only), any station that tries to associate
++with the Multi-AP information element will be denied. That is also the only
++difference with 'multi_ap' set to 0: in the latter case, the Multi-AP
++information element is simply ignored.
++
++In summary, this is the end-to-end behaviour for a backhaul BSS (i.e.,
++multi_ap_backhaul_sta=1 in wpa_supplicant on STA, and multi_ap=1 or 3 in
++hostapd on AP). Note that point 1 means that hostapd must not be configured
++with WPS support on the backhaul BSS (multi_ap=1). hostapd does not check for
++that.
++
++1. Backhaul BSS beacons do not advertise WPS support (other than that, nothing
++ multi-ap specific).
++2. STA sends authentication req (nothing multi-ap specific).
++3. AP sends authentication resp (nothing multi-ap specific).
++4. STA sends association req with Multi-AP IE.
++5. AP send association resp with Multi-AP IE.
++6. STA and AP both use 4-address mode for data.
++
++
++WPS support
++-----------
++
++WPS requires more special handling. WPS must only be advertised on fronthaul
++SSIDs, not on backhaul SSIDs, so WPS should not be enabled on a backhaul-only
++SSID in hostapd.conf. The WPS configuration purely works on the fronthaul SSID.
++When a WPS M1 message has an additional subelement that indicates a request for
++a multi-AP backhaul link, hostapd must not respond with the normal fronthaul
++SSID credentials; instead, it should respond with the (potentially different)
++backhaul SSID credentials.
++
++To support this, hostapd has the 'multi_ap_backhaul_ssid',
++'multi_ap_backhaul_wpa_psk' and 'multi_ap_backhaul_wpa_passphrase' options.
++When these are set on an SSID with WPS, they are used instead of the normal
++credentials when hostapd receives a WPS M1 message with the Multi-AP IE. Only
++WPA2 Personal is supported in the Multi-AP specification, so there is no need
++to specify authentication or encryption options. For the backhaul credentials,
++per-device PSK is not supported.
++
++If the SSID is a simultaneous backhaul and fronthaul SSID, there is no need to
++specify the backhaul credentials, since the backhaul and fronthaul credentials
++are identical.
++
++To enable the Multi-AP backhaul STA feature when it performs WPS, a new
++parameter has been introduced to the WPS_PBC control interface call.
++When this option is set, it adds the multi-AP backhaul subelement to
++the association and M1 messages. It then configures the new SSID with
++'multi_ap_backhaul_sta=1'. Note that this means that if the AP does not
++follow the Multi-AP specification, wpa_supplicant will fail to
++associate.
++
++In summary, this is the end-to-end behaviour for WPS of a backhaul link (i.e.,
++multi_ap=1 option is given in the wps_pbc call on the STA side, and multi_ap=2
++and multi_ap_backhaul_ssid and either multi_ap_backhaul_wpa_psk or
++multi_ap_backhaul_wpa_passphrase are set to the credentials of a backhaul SSID
++in hostapd on registrar AP).
++
++1. Fronthaul BSS beacons advertise WPS support (nothing multi-ap specific).
++2. Enrollee sends authentication req (nothing multi-ap specific).
++3. AP sends authentication resp (nothing multi-ap specific).
++4. Enrollee sends association req with Multi-AP IE.
++5. AP send association resp with Multi-AP IE.
++6. Enrollee sends M1 with additional Multi-AP subelement
++7. AP sends M8 with backhaul instead of fronthaul credentials.
++8. Enrollee sends Deauth.
