VLAN: Separate station grouping and uplink configuration Separate uplink configuration (IEEE 802.1q VID) and grouping of stations into AP_VLAN interfaces. The int vlan_id will continue to identify the AP_VLAN interface the station should be assigned to. Each AP_VLAN interface corresponds to an instance of struct hostapd_vlan that is uniquely identified by int vlan_id within an BSS. New: Each station and struct hostapd_vlan holds a struct vlan_description vlan_desc member that describes the uplink configuration requested. Currently this is just an int untagged IEEE 802.1q VID, but can be extended to tagged VLANs and other settings easily. When the station was about to be assigned its vlan_id, vlan_desc and vlan_id will now be set simultaneously by ap_sta_set_vlan(). So sta->vlan_id can still be tested for whether the station needs to be moved to an AP_VLAN interface. To ease addition of tagged VLAN support, a member notempty is added to struct vlan_description. Is is set to 1 if an untagged or tagged VLAN assignment is requested and needs to be validated. The inverted form allows os_zalloc() to initialize an empty description. Though not depended on by the code, vlan_id assignment ensures: * vlan_id = 0 will continue to mean no AP_VLAN interface * vlan_id < 4096 will continue to mean vlan_id = untagged vlan id with no per_sta_vif and no extra tagged vlan. * vlan_id > 4096 will be used for per_sta_vif and/or tagged vlans. This way struct wpa_group and drivers API do not need to be changed in order to implement tagged VLANs or per_sta_vif support. DYNAMIC_VLAN_* will refer to (struct vlan_description).notempty only, thus grouping of the stations for per_sta_vif can be used with DYNAMIC_VLAN_DISABLED, but not with CONFIG_NO_VLAN, as struct hostapd_vlan is still used to manage AP_VLAN interfaces. MAX_VLAN_ID will be checked in hostapd_vlan_valid and during setup of VLAN interfaces and refer to IEEE 802.1q VID. VLAN_ID_WILDCARD will continue to refer to int vlan_id. Renaming vlan_id to vlan_desc when type changed from int to struct vlan_description was avoided when vlan_id was also used in a way that did not depend on its type (for example, when passed to another function). Output of "VLAN ID %d" continues to refer to int vlan_id, while "VLAN %d" will refer to untagged IEEE 802.1q VID. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>

Add workaround for race condition with AssocResp TX status It may take some time for the TX status to be delivered for a (Re)Association Response frame and if any Data frames are received during that time, they may end up getting dropped as Class 3 frames in not-associated state. This results in a Disassociation frame being sent to the station and it assuming that the association has been lost. Work around the issue by remembering that the (Re)Association Request has already been accepted and skip the Deauth/Disassoc sending because of the possible Class 3 frames before the TX status callback is received.

WPS: Wait for EAPOL-Start unless WPS 2.0 station as workaround Extend the code that waits for the station to send EAPOL-Start before initiating EAPOL authenticator operations to cover the case where the station includes WPS IE in (Re)Association Request frame if that IE does not include support for WPS 2.0. While this should not really be needed, this may help with some deployed WPS 1.0 stations that do not support EAPOL operations correctly and may get confused of the EAP-Request/Identity packets that would show up twice if EAPOL-Start is transmitted.

Fix Deauth/Disassoc callback handling with test frames The Deauth/Disassoc TX status callbacks were ending up kicking the station entry from kernel driver when test functionality was used to inject Deauth/Disassoc frames from the AP with the purpose of leaving the local association in place. Fix this by using STA flags to figure out whether there was a pending callback for the frame that we need to act on. In addition, add forgotten functionality for the Disassoc TX status callback to match the behavior with Deauth.

AP: Save EAPOL received before Association Response ACK There is a race condition in which AP might receive the EAPOL-Start frame (from the just-associated station) before the TX completion of the Association Response frame.

Solve this by saving EAPOL frames from authenticated-but-not-associated stations, and handling them during the Association Response frame TX completion processing.

AP: Add support for Proxy ARP, DHCP snooping mechanism Proxy ARP allows the AP devices to keep track of the hardware address to IP address mapping of the STA devices within the BSS. When a request for such information is made (i.e., ARP request, Neighbor Solicitation), the AP will respond on behalf of the STA device within the BSS. Such requests could originate from a device within the BSS or also from the bridge. In the process of the AP replying to the request (i.e., ARP reply, Neighbor Advertisement), the AP will drop the original request frame. The relevant STA will not even know that such information was ever requested. This feature is a requirement for Hotspot 2.0, and is defined in IEEE Std 802.11-2012, 10.23.13. While the Proxy ARP support code mainly resides in the kernel bridge code, in order to optimize the performance and simplify kernel implementation, the DHCP snooping code was added to the hostapd.

Fix race condition between AssocResp callback and 4addr event It is apparently possible for the NL80211_CMD_UNEXPECTED_4ADDR_FRAME event to be delivered to hostapd before the NL80211_CMD_FRAME_TX_STATUS event for (Re)Association Response frame. This resulted in the 4-address WDS mode not getting enabled for a STA. This could occur in particular when operating under heavy load and the STA is reconnecting to the same AP in a sequence where Deauthentication frame is followed immediately by Authentication frame and the driver event processing gets delayed due to removal of the previous netdev taking time in the middle of this sequence. Fix this by recording a pending item for 4-address WDS enabling if the NL80211_CMD_UNEXPECTED_4ADDR_FRAME event would have been dropped due to incompleted association and then process this pending item if the TX status for the (Re)Association Response frame is received and it shows that the frame was acknowledged.

Delay STA entry removal until Deauth/Disassoc TX status in AP mode This allows the driver to use PS buffering of Deauthentication and Disassociation frames when the STA is in power save sleep. The STA entry (and PTK) will be removed from the kernel only after the Deauth/Disassoc has been transmitted (e.g., when the STA wakes up). A hardcoded two second timeout is used to limit the length of this window should the driver fail to deliver the frame (e.g., the STA is out of range and does not wake up). The kernel STA entry is marked unauthorized during the wait to avoid accepting Data frames from the STA that we have decided to disconnect. This behavior is available only with drivers that provide TX status events for Deauth/Disassoc frames (nl80211 at this point). Other drivers continue to use the previous behavior where the STA entry is removed immediately.

VLAN: Separate station grouping and uplink configuration Separate uplink configuration (IEEE 802.1q VID) and grouping of stations into AP_VLAN interfaces. The int vlan_id will continue to identify the AP_VLAN interface the station should be assigned to. Each AP_VLAN interface corresponds to an instance of struct hostapd_vlan that is uniquely identified by int vlan_id within an BSS. New: Each station and struct hostapd_vlan holds a struct vlan_description vlan_desc member that describes the uplink configuration requested. Currently this is just an int untagged IEEE 802.1q VID, but can be extended to tagged VLANs and other settings easily. When the station was about to be assigned its vlan_id, vlan_desc and vlan_id will now be set simultaneously by ap_sta_set_vlan(). So sta->vlan_id can still be tested for whether the station needs to be moved to an AP_VLAN interface. To ease addition of tagged VLAN support, a member notempty is added to struct vlan_description. Is is set to 1 if an untagged or tagged VLAN assignment is requested and needs to be validated. The inverted form allows os_zalloc() to initialize an empty description. Though not depended on by the code, vlan_id assignment ensures: * vlan_id = 0 will continue to mean no AP_VLAN interface * vlan_id < 4096 will continue to mean vlan_id = untagged vlan id with no per_sta_vif and no extra tagged vlan. * vlan_id > 4096 will be used for per_sta_vif and/or tagged vlans. This way struct wpa_group and drivers API do not need to be changed in order to implement tagged VLANs or per_sta_vif support. DYNAMIC_VLAN_* will refer to (struct vlan_description).notempty only, thus grouping of the stations for per_sta_vif can be used with DYNAMIC_VLAN_DISABLED, but not with CONFIG_NO_VLAN, as struct hostapd_vlan is still used to manage AP_VLAN interfaces. MAX_VLAN_ID will be checked in hostapd_vlan_valid and during setup of VLAN interfaces and refer to IEEE 802.1q VID. VLAN_ID_WILDCARD will continue to refer to int vlan_id. Renaming vlan_id to vlan_desc when type changed from int to struct vlan_description was avoided when vlan_id was also used in a way that did not depend on its type (for example, when passed to another function). Output of "VLAN ID %d" continues to refer to int vlan_id, while "VLAN %d" will refer to untagged IEEE 802.1q VID. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>

Remove VLAN interface on STA free Currently, vlan_remove_dynamic() is only called when the station VLAN ID is changed (ap_sta_bind_vlan), but not when the station is freed. So dynamic VLAN interfaces are not removed actually except within 1x reauthentification VLAN ID change, although most of the code is already there. This patch fixes this by calling vlan_remove_dynamic() in ap_free_sta(). It cannot just use sta->vlan_id for this, as this might have been changed without calling ap_sta_bind_vlan() (ap/ieee802_11.c:handle_auth fetches from RADIUS cache for WPA-PSK), thus reference counting might not have been updated. Additionally, reference counting might get wrong due to old_vlanid = 0 being passed unconditionally, thus increasing the reference counter multiple times. So tracking the currently assigned (i.e., dynamic_vlan counter increased) VLAN is done in a new variable sta->vlan_id_bound. Therefore, the old_vlan_id argument of ap_sta_bind_vlan() is no longer needed and setting the VLAN for the sta in driver happens unconditionally. Additionally, vlan->dynamic_vlan is only incremented when it actually is a dynamic VLAN. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>

mesh: Add support for PMKSA caching This patch add functionality of mesh SAE PMKSA caching. If the local STA already has peer's PMKSA entry in the cache, skip SAE authentication and start AMPE with the cached value. If the peer does not support PMKSA caching or does not have the local STA's PMKSA entry in the cache, AMPE will fail and the PMKSA cache entry of the peer will be removed. Then STA retries with ordinary SAE authentication. If the peer does not support PMKSA caching and the local STA uses no_auto_peer=1, the local STA can not retry SAE authentication because NEW_PEER_CANDIDATE event cannot start SAE authentication when no_auto_peer=1. So this patch extends MESH_PEER_ADD command to use duration(sec). Throughout the duration, the local STA can start SAE authentication triggered by NEW_PEER_CANDIDATE even though no_auto_peer=1.

AP: Drop retransmitted auth/assoc/action frames It is possible that a station device might miss an ACK for an authentication, association, or action frame, and thus retransmit the same frame although the frame is already being processed in the stack. While the duplicated frame should really be dropped in the kernel or firmware code where duplicate detection is implemented for data frames, it is possible that pre-association cases are not fully addressed (which is the case at least with mac80211 today) and the frame may be delivered to upper layer stack. In such a case, the local AP will process the retransmitted frame although it has already handled the request, which might cause the station to get confused and as a result disconnect from the AP, blacklist it, etc. To avoid such a case, save the sequence control of the last processed management frame and in case of retransmissions drop them.

Passive Client Taxonomy Implement the signature mechanism described in the paper "Passive Taxonomy of Wifi Clients using MLME Frame Contents" published by Denton Gentry and Avery Pennarun. http://research.google.com/pubs/pub45429.html https://arxiv.org/abs/1608.01725 This involves: 1. Add a CONFIG_TAXONOMY compile option. Enabling taxonomy incurs a memory overhead of up to several kilobytes per associated station. 2. If enabled, store the Probe Request and (Re)Associate Request frame in struct sta_info. 3. Implement code to extract the ID of each Information Element, plus selected fields and bitmasks from certain IEs, into a descriptive text string. This is done in a new source file, src/ap/taxonomy.c. 4. Implement a "signature qq:rr:ss:tt:uu:vv" command in hostapd_cli to retrieve the signature. Signatures take the form of a text string. For example, a signature for the Nexus 5X is: wifi4|probe:0,1,127,45,191,htcap:01ef,htagg:03,htmcs:0000ffff,vhtcap:338061b2, vhtrxmcs:030cfffa,vhttxmcs:030cfffa,extcap:00000a0201000040|assoc:0,1,48,45, 221(0050f2,2),191,127,htcap:01ef,htagg:03,htmcs:0000ffff,vhtcap:339071b2, vhtrxmcs:030cfffa,vhttxmcs:030cfffa,extcap:0000000000000040 Signed-off-by: dgentry@google.com (Denton Gentry) Signed-off-by: denny@geekhold.com (Denton Gentry) Signed-off-by: rofrankel@google.com (Richard Frankel) Signed-off-by: richard@frankel.tv (Richard Frankel)

Remove VLAN interface on STA free Currently, vlan_remove_dynamic() is only called when the station VLAN ID is changed (ap_sta_bind_vlan), but not when the station is freed. So dynamic VLAN interfaces are not removed actually except within 1x reauthentification VLAN ID change, although most of the code is already there. This patch fixes this by calling vlan_remove_dynamic() in ap_free_sta(). It cannot just use sta->vlan_id for this, as this might have been changed without calling ap_sta_bind_vlan() (ap/ieee802_11.c:handle_auth fetches from RADIUS cache for WPA-PSK), thus reference counting might not have been updated. Additionally, reference counting might get wrong due to old_vlanid = 0 being passed unconditionally, thus increasing the reference counter multiple times. So tracking the currently assigned (i.e., dynamic_vlan counter increased) VLAN is done in a new variable sta->vlan_id_bound. Therefore, the old_vlan_id argument of ap_sta_bind_vlan() is no longer needed and setting the VLAN for the sta in driver happens unconditionally. Additionally, vlan->dynamic_vlan is only incremented when it actually is a dynamic VLAN. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>

VLAN: Separate station grouping and uplink configuration Separate uplink configuration (IEEE 802.1q VID) and grouping of stations into AP_VLAN interfaces. The int vlan_id will continue to identify the AP_VLAN interface the station should be assigned to. Each AP_VLAN interface corresponds to an instance of struct hostapd_vlan that is uniquely identified by int vlan_id within an BSS. New: Each station and struct hostapd_vlan holds a struct vlan_description vlan_desc member that describes the uplink configuration requested. Currently this is just an int untagged IEEE 802.1q VID, but can be extended to tagged VLANs and other settings easily. When the station was about to be assigned its vlan_id, vlan_desc and vlan_id will now be set simultaneously by ap_sta_set_vlan(). So sta->vlan_id can still be tested for whether the station needs to be moved to an AP_VLAN interface. To ease addition of tagged VLAN support, a member notempty is added to struct vlan_description. Is is set to 1 if an untagged or tagged VLAN assignment is requested and needs to be validated. The inverted form allows os_zalloc() to initialize an empty description. Though not depended on by the code, vlan_id assignment ensures: * vlan_id = 0 will continue to mean no AP_VLAN interface * vlan_id < 4096 will continue to mean vlan_id = untagged vlan id with no per_sta_vif and no extra tagged vlan. * vlan_id > 4096 will be used for per_sta_vif and/or tagged vlans. This way struct wpa_group and drivers API do not need to be changed in order to implement tagged VLANs or per_sta_vif support. DYNAMIC_VLAN_* will refer to (struct vlan_description).notempty only, thus grouping of the stations for per_sta_vif can be used with DYNAMIC_VLAN_DISABLED, but not with CONFIG_NO_VLAN, as struct hostapd_vlan is still used to manage AP_VLAN interfaces. MAX_VLAN_ID will be checked in hostapd_vlan_valid and during setup of VLAN interfaces and refer to IEEE 802.1q VID. VLAN_ID_WILDCARD will continue to refer to int vlan_id. Renaming vlan_id to vlan_desc when type changed from int to struct vlan_description was avoided when vlan_id was also used in a way that did not depend on its type (for example, when passed to another function). Output of "VLAN ID %d" continues to refer to int vlan_id, while "VLAN %d" will refer to untagged IEEE 802.1q VID. Signed-off-by: Michael Braun <michael-dev@fami-braun.de>

Delay STA entry removal until Deauth/Disassoc TX status in AP mode This allows the driver to use PS buffering of Deauthentication and Disassociation frames when the STA is in power save sleep. The STA entry (and PTK) will be removed from the kernel only after the Deauth/Disassoc has been transmitted (e.g., when the STA wakes up). A hardcoded two second timeout is used to limit the length of this window should the driver fail to deliver the frame (e.g., the STA is out of range and does not wake up). The kernel STA entry is marked unauthorized during the wait to avoid accepting Data frames from the STA that we have decided to disconnect. This behavior is available only with drivers that provide TX status events for Deauth/Disassoc frames (nl80211 at this point). Other drivers continue to use the previous behavior where the STA entry is removed immediately.

AP: Fix Deauth/Disassoc TX status timeout handling The ap_sta_deauth_cb and ap_sta_disassoc_cb eloop timeouts are used to clear a disconnecting STA from the kernel driver if the STA did not ACK the Deauthentication/Disassociation frame from the AP within two seconds. However, it was possible for a STA to not ACK such a frame, e.g., when the disconnection happened due to hostapd pruning old associations from other BSSes and the STA was not on the old channel anymore. If that same STA then started a new authentication/association with the BSS, the two second timeout could trigger during this new association and result in the STA entry getting removed from the kernel. Fix this by canceling these eloop timeouts when receiving an indication of a new authentication or association. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>

Use eloop timeout for post-EAP-Failure wait before disconnection Previously, os_sleep() was used to block the hostapd (or wpa_supplicant AP/P2P GO mode) processing between sending out EAP-Failure and disconnecting the STA. This is not ideal for couple of reasons: it blocks all other parallel operations in the process and it leaves a window during which the station might deauthenticate and the AP would have no option for reacting to that before forcing out its own Deauthentication frame which could go out after the STA has already started new connection attempt. Improve this design by scheduling an eloop timeout of 10 ms instead of the os_sleep() call and perform the delayed operations from the eloop callback function. This eloop timeout is cancelled if the STA disconnects or initiates a new connection attempt before the 10 ms time is reached. This gets rid of the confusing extra Deauthentication frame in cases where the STA reacts to EAP-Failure by an immediate deauthentication. Signed-off-by: Jouni Malinen <j@w1.fi>
