The LINK cmd host api has been updated. Align the driver to the new changes. Also, temporary use mac_id for link_id. Using the phy_id as the link_id is wrong since we might have 2 macs operating on the same phy - in this case we will have 2 different links (one for each mac) with the same link_id. On the other hand, since we don't have MLO implemented yet, we won't have 2 different links of the same mac. Therefore, we can use the mac_id as the link_id. Signed-off-by:

Currently we're setting the sta->addr as the peers address only if the iftype is NL80211_IFTYPE_AP, otherwise we are setting the bssid to be the addr. This causes bugs in TDLS. Fix this by always using the sta->addr. Signed-off-by:

During CSA the PHY used by the link is changing, So the driver needs to modify the links phy to the FW. Currently the driver is doing it by removing the link and adding a new one with the new phy_id, but the FW expects the link only to be modified. Fix this by modifying the links phy_id instead of removing it and adding a new one Signed-off-by:

This bitmap indicates what fields of the cmd got changed. A field will be ignored by the FW if the corresponding flag wasn't set. There are a few cases in which we currently set the wrong bits when sending this cmd, which caused FW asserts. Fix this by setting the correct bits in each case.

These flows are the same in both MLD API and the current API, except for the commands that are being sent during this flows. Instead of checking each time before calling these floews what API we use and then call the correct function, call always the old one, which in turn will call the new one in case we're using the MLD API.

Miri Korenblit authored
This flow is almost the same for both MLD and non-MLD modes, except for some function calls. Therefore there is no reason to add an MLD version of this flow. Instead - put the parts that are unique for each mode in helper functions, and in the next patch each version of this flow will call the common part with pointers to its specific helper functions.

Miri Korenblit authored
WE can't mix between the new MLD API and the old API. I.e. - we can't send one of the new cmds and then one of the old ones. This will cause a FW assert. So we need an indication what API should be used. We use the new API if: 1. FW supports it 2. We are registered to mac80211 with the new MLD ops Add an indication which will only be true if both conditions are true. Signed-off-by:

Split iwl_mvm_sta into general and link specific parts. As a first step, all link dependent parameters reside in deflink.

Gregory Greenman authored
In MLO, some fields of iwl_mvm_vif should be defined in the context of a link. Define a separate structure for these fields and add a deflink object to hold it as part of iwl_mvm_vif. Non-MLO legacy code will use only deflink object while MLO related code will use the corresponding link from the link array. It follows the strategy applied in mac80211 for introducing MLO changes. The below spatch takes care of updating all driver code to access fields separated into MLD specific data structure via deflink (need to convert all references to the fields listed in var to deflink.var and also to take care of calls like iwl_mvm_vif_from_mac80211(vif)->field). @iwl_mld_vif@ struct iwl_mvm_vif *v; struct ieee80211_vif *vv; identifier fn; identifier var = {bssid, ap_sta_id, bcast_sta, mcast_sta, beacon_stats, smps_requests, probe_resp_data, he_ru_2mhz_block, cab_queue, phy_ctxt, queue_params}; @@ ( v-> - var + deflink.var | fn(vv)-> - var + deflink.var ) Signed-off-by: -

There is a 64-bit division in iwl_mvm_get_crosstimestamp_fw(), which results in a link failure when building 32-bit architectures with clang: ld.lld: error: undefined symbol: __udivdi3 >>> referenced by ptp.c >>> drivers/net/wireless/intel/iwlwifi/mvm/ptp.o:(iwl_mvm_phc_get_crosstimestamp) in archive vmlinux.a GCC has optimizations for division by a constant that clang does not implement, so this issue is not visible when building with GCC. Use the 64-bit division helper div_u64(), which takes a u64 dividend and u32 divisor, which matches this situation and prevents the emission of a libcall for the division.

PMSR (a.k.a. peer measurement) is generalized measurement between two devices with Wi-Fi support. And currently FTM (a.k.a. fine time measurement or flight time measurement) is the one and only measurement. Add the necessary functionality to allow mac80211_hwsim to report PMSR result. The result would come from the wmediumd, where other Wi-Fi devices' information are kept. mac80211_hwsim only need to deliver the result to the userspace. In detail, add new mac80211_hwsim attributes HWSIM_CMD_REPORT_PMSR, and HWSIM_ATTR_PMSR_RESULT. When mac80211_hwsim receives the PMSR result with command HWSIM_CMD_REPORT_PMSR and detail with attribute HWSIM_ATTR_PMSR_RESULT, received data is parsed to cfg80211_pmsr_result and resent to the userspace by cfg80211_pmsr_report(). To help receive the details of PMSR result, hwsim_rate_info_attributes is added to receive rate_info without complex bitrate calculation. (i.e. send rate_info without adding inverse of nl80211_put_sta_rate()). Signed-off-by:

PMSR (a.k.a. peer measurement) is generalized measurement between two Wi-Fi devices. And currently FTM (a.k.a. fine time measurement or flight time measurement) is the one and only measurement. FTM is measured by RTT (a.k.a. round trip time) of packets between two Wi-Fi devices. Add necessary functionalities for mac80211_hwsim to start PMSR request by passthrough the request to wmediumd via virtio. mac80211_hwsim can't measure RTT for real because mac80211_hwsim the software simulator and packets are sent almost immediately for real. This change expect wmediumd to have all the location information of devices, so passthrough requests to wmediumd. In detail, add new mac80211_hwsim command HWSIM_CMD_ABORT_PMSR. When mac80211_hwsim receives the PMSR start request via ieee80211_ops.start_pmsr, the received cfg80211_pmsr_request is resent to the wmediumd with command HWSIM_CMD_START_PMSR and attribute HWSIM_ATTR_PMSR_REQUEST.

PMSR (a.k.a. peer measurement) is generalized measurement between two Wi-Fi devices. And currently FTM (a.k.a. fine time measurement or flight time measurement) is the one and only measurement. FTM is measured by RTT (a.k.a. round trip time) of packets between two Wi-Fi devices. Add necessary functionality to allow mac80211_hwsim to be configured with PMSR capability. The capability is mandatory to accept incoming PMSR request because nl80211_pmsr_start() ignores incoming the request without the PMSR capability. In detail, add new mac80211_hwsim attribute HWSIM_ATTR_PMSR_SUPPORT. HWSIM_ATTR_PMSR_SUPPORT is used to set PMSR capability when creating a new radio. To send extra capability details, HWSIM_ATTR_PMSR_SUPPORT can have nested PMSR capability attributes defined in the nl80211.h. Data format is the same as cfg80211_pmsr_capabilities. If HWSIM_ATTR_PMSR_SUPPORT is specified, mac80211_hwsim builds cfg80211_pmsr_capabilities and sets wiphy.pmsr_capa. Signed-off-by:

As per IEEE Std 802.11ax-2021, 11.1.3.8.3 Discovery of a nontransmitted BSSID profile, an EMA AP that transmits a Beacon frame carrying a partial list of nontransmitted BSSID profiles should include in the frame a Reduced Neighbor Report element carrying information for at least the nontransmitted BSSIDs that are not present in the Multiple BSSID element carried in that frame. Add new nested attribute NL80211_ATTR_EMA_RNR_ELEMS to support the above. Number of RNR elements must be more than or equal to the number of MBSSID elements. This attribute can be used only when EMA is enabled. Userspace is responsible for splitting the RNR into multiple elements such that each element excludes the non-transmitting profiles already included in the MBSSID element (%NL80211_ATTR_MBSSID_ELEMS) at the same index. Each EMA beacon will be generated by adding MBSSID and RNR elements at the same index. If the userspace provides more RNR elements than the number of MBSSID elements then these will be added in every EMA beacon. Signed-off-by:

Add APIs to generate an array of beacons for an EMA AP (enhanced multiple BSSID advertisements), each including a single MBSSID element. EMA profile periodicity equals the count of elements. - ieee80211_beacon_get_template_ema_list() - Generate and return all EMA beacon templates. Drivers must call ieee80211_beacon_free_ema_list() to free the memory. No change in the prototype for the existing API, ieee80211_beacon_get_template(), which should be used for non-EMA AP. - ieee80211_beacon_get_template_ema_index() - Generate a beacon which includes the multiple BSSID element at the given index. Drivers can use this function in a loop until NULL is returned which indicates end of available MBSSID elements. - ieee80211_beacon_free_ema_list() - free the memory allocated for the list of EMA beacon templates. Modify existing functions ieee80211_beacon_get_ap(), ieee80211_get_mbssid_beacon_len() and ieee80211_beacon_add_mbssid() to accept a new parameter for EMA index. Signed-off-by:

Currently when NL80211_SCAN_FLAG_COLOCATED_6GHZ is set in the scan flags, in addition to the co-located APs, PSC channels in the 6 GHz band would also be scanned if the user space has asked for it. In other words, the scan would happen on PSC channels & co-located 6 GHz channels that were reported in the RNR IE.

Previously, fast xmit only worked on interface types where initially a sta lookup is performed, and a cached header can be attached to the sta, requiring only some fields to be updated at runtime. This technique is not directly applicable for a mesh device type due to the dynamic nature of the topology and protocol. There are more addresses that need to be filled, and there is an extra header with a dynamic length based on the addressing mode. Change the code to cache entries contain a copy of the mesh subframe header + bridge tunnel header, as well as an embedded struct ieee80211_fast_tx, which contains the information for building the 802.11 header. Add a mesh specific early fast xmit call, which looks up a cached entry and adds only the mesh subframe header, before passing it over to the generic fast xmit code. To ensure the changes in network are reflected in these cached headers, flush affected cached entries on path changes, as well as other conditions that currently trigger a fast xmit check in other modes (key changes etc.) This code is loosely based on a previous implementation by: Sriram R <quic_srirrama@quicinc.com> Cc: Sriram R <quic_srirrama@quicinc.com> Signed-off-by:
