This patch series adds initial support for Multi-Link operation AP. First, it refactors the driver_nl80211 to support multiple links by introducing internal structs to hold the links and API's to configure links and link stations. Next it allows to start multiple hostapd_iface's and bind them to the same underlying network interface and driver instance. Each hostapd_iface represents a separate link BSS. The events are forwarded to the correct hapd according to the link id. Afterwards we implement advertising and parsing of basic MLE and RNR in beacons, probe responses and during authentication and association stages. Finally, implement WPA authenticator for MLO and also adjust SAE to use the MLD addresses for commit derivation. It needs to be noticed, that this series are minimal and add a very basic MLO implementation which allow to establish SAE/OWE connection and intended to be used mainly for testing purposes. --- v2 changes: - Fixed most of the comments from v1 - Fixed several bugs with non-MLO STA connecting to MLO AP - Auto assignment of mld_link_id - Fetching MLD/EML capabilities from kernel - Proper AID allocation Andrei Otcheretianski (23): AP: Add some basic MLD configuration options driver: Add MLD link id to AP parameters driver_nl80211: Support setting up an AP on a specified link AP: Allow starting multiple interfaces within single MLD driver_nl80211: Select freq according to transmitting link AP: Support building basic Multi-Link Element AP: MLO: Handle ML element during authentication AP: MLO: Add MLO information to hostapd_sta_add_params struct AP: Support AID allocation for MLD AP: MLO: Process EHT ML element from association request AP: MLO: Add ML element to association response AP: Print MLD info in STATUS command AP/wpa_supplicant/driver: Add link id to send eapol callbacks driver_nl80211: use frequency to determine mld link for MLME events AP: Forward link specific events WPA_AUTH: MLO: Store MLO link information WPA_AUTH: MLO: Add MLO KDEs to message 3 of the 4-way handshake AP: Use MLD address for SAE commit derivation AP: Don't process SAE/OWE assoc info on MLD links AP: Use MLD address for traffic tests AP: Forward EAPOL frames and status to correct BSS driver_nl80211: Store and report link id for MLO control frames tests: Add basic MLD hwsim tests Benjamin Berg (3): driver_nl80211: Rename the per iface-type capabilities struct nl80211: Add support to fetch EML/MLD capabilities AP: MLO: Retrieve EML and MLD capabilities from driver Ilan Peer (18): driver: Allow to provide a link ID when setting a channel AP: Include an RNR element in beacons for MLD AP AP: MLO: Make 802.1X SM, authserv and radius client singletons AP: Match Rx frames against MLD address AP: MLO: Handle association callback AP: MLO: Handle deauth/disassoc of MLD station AP: MLO: Handle 802.1X port authorization driver: Specify link ID for 'send_mlme' and 'sta_deauth' callbacks AP: Do not prune station when adding a link station AP: Handle TX status for MLD AP AP: Provide the link ID for an MLD setting when setting VLAN AP/driver: Add link id to the set_tx_queue_params() callback WPA_AUTH: MLO: Add MAC KDE to 1st message in 4-way handshake WPA_AUTH: MLO: Validate MLO KDEs in 2nd message of 4-way handshake WPA_AUTH: MLO: Validate MLO KDEs in 4th message of 4-way handshake WPA_AUTH: MLO: Add MLO KDEs to message 1 of the group handshake WPA_AUTH: MLO: Get the correct AA and SPA based on MLD operation AP: Specify the link ID for set_key() callback hostapd/config_file.c | 4 + hostapd/ctrl_iface.c | 7 +- hostapd/main.c | 90 +++ src/ap/ap_config.h | 8 + src/ap/ap_drv_ops.c | 73 +- src/ap/ap_drv_ops.h | 25 +- src/ap/authsrv.c | 38 ++ src/ap/beacon.c | 55 +- src/ap/ctrl_iface_ap.c | 15 + src/ap/drv_callbacks.c | 131 +++- src/ap/hostapd.c | 148 +++- src/ap/hostapd.h | 14 +- src/ap/ieee802_11.c | 1017 ++++++++++++++++++++++++---- src/ap/ieee802_11.h | 11 + src/ap/ieee802_11_eht.c | 684 +++++++++++++++++++ src/ap/ieee802_1x.c | 109 ++- src/ap/sta_info.c | 43 +- src/ap/sta_info.h | 34 + src/ap/utils.c | 14 +- src/ap/wpa_auth.c | 652 +++++++++++++++++- src/ap/wpa_auth.h | 48 ++ src/ap/wpa_auth_glue.c | 107 ++- src/ap/wpa_auth_i.h | 16 + src/common/ieee802_11_defs.h | 11 + src/common/wpa_common.h | 3 + src/drivers/driver.h | 52 +- src/drivers/driver_nl80211.c | 443 ++++++++---- src/drivers/driver_nl80211.h | 11 +- src/drivers/driver_nl80211_capa.c | 30 +- src/drivers/driver_nl80211_event.c | 35 +- tests/hwsim/example-hostapd.config | 1 + tests/hwsim/hostapd.py | 77 ++- tests/hwsim/hwsim.py | 11 +- tests/hwsim/test_eht.py | 293 ++++++++ wpa_supplicant/driver_i.h | 20 +- wpa_supplicant/ibss_rsn.c | 4 +- wpa_supplicant/wpas_glue.c | 2 +- 37 files changed, 3929 insertions(+), 407 deletions(-) -- 2.38.1 _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
