FT: Remove optional fields from RSNE when using PMF The PMKIDCount, PMKID List, and Group Management Cipher Suite fields are optional to include in the RSNE in cases where these would not have values that are different from the default values. In practice, PMKIDCount is always 0 in Beacon and Probe Response frames, so the only field of these that could have a non-default value is Group Management Cipher Suite. When BIP is used, that field is not needed either due to BIP being the default cipher when PMF is enabled. Remove these fields from RSNE when BIP is used to save six octets in Beacon and Probe Response frames. In addition to reduced frame length, this is a workaround for interoperability issues with iOS 8.4 in cases where FT and PMF are enabled. iOS seems to be rejecting EAPOL-Key msg 3/4 during FT initial mobility domain association if the RSNE includes the PMKIDCount field.

Fix cipher suite selector default value in RSNE for DMG 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.

hostapd: Work around an interop connection issue in FT-PSK + WPA-PSK While the AP is configured to enable both FT-PSK and WPA-PSK, an HP printer request both AKMs (copied from AP?) in Association Request frame, but don't add MDIE and don't use FT. This results in the connection failing. Next in logs we see: RSN: Trying to use FT, but MDIE not included IE - hexdump(len=26): 30 18 01 00 00 0f ac 04 01 00 00 0f ac 04 02 00 00 0f ac 02 00 0f ac 04 00 00 This is seen with some HP and Epson printers. Work around this by stripping FT AKM(s) when MDE is not present and there is still a non-FT AKM available. Signed-off-by: Janusz Dziedzic <janusz@plumewifi.com>

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>

AP: Support Extended Key ID Support Extended Key ID in hostapd according to IEEE Std 802.11-2016. Extended Key ID allows to rekey pairwise keys without the otherwise unavoidable MPDU losses on a busy link. The standard is fully backward compatible, allowing an AP to serve STAs with and without Extended Key ID support in the same BSS. Signed-off-by: Alexander Wetzel <alexander@wetzel-home.de>

OWE: Fix association rejection behavior If association failed for any non-OWE specific reason, the previous implementation tried to add the OWE related IEs into the (Re)Association Response frame. This is not needed and could actually result in dereferencing a NULL pointer. Fix this by adding those OWE related IEs only for successful association and only if the RSN state machine has been initialized. Signed-off-by: Jouni Malinen <j@w1.fi>

OWE: Clean up pointer check in a testing code path Check wpa_auth_write_assoc_resp_owe() return value to keep static analyzers happier. The code path where this could happen is not really reachable due to the separate hapd->conf->own_ie_override check and wpa_auth_write_assoc_resp_owe() returning NULL only in an error case in the override path. Furthermore, clean up the pointer return value to use a proper pointer (NULL vs. 0). Signed-off-by: Ashok Ponnaiah <aponnaia@codeaurora.org>

FILS: Add RSNE into (Re)Association Response frame This AP behavior was missing from IEEE Std 802.11ai-2016, but it is needed for the RSNE validation to work correctly and for a FILS STA to be able to perform the mandatory check for RSNE matching when processing the (Re)Association Response frame (as described in 802.11ai). REVmd will be updating the standard to cover this AP case, so prepare the implementation to match that. Without this, a FILS STA might reject association whenever using FILS authentication.
