2024-10-23wifi: iwlwifi: mvm: Add support for prep_add_interface() callbackIlan Peer
Implement the prep_add_interface() callback, so that in case EMLSR is active and an AP or a P2P interface is do to be added, EMLSR would be blocked. Add a delayed work, so that in case that the interface was not eventually added, EMLSR would be unblocked after 5 seconds.

2024-10-23wifi: mac80211: call rate_control_rate_update() for link STAJohannes Berg
In order to update the right link information, call the update rate_control_rate_update() with the right link_sta, and then pass that through to the driver's sta_rc_update() method. The software rate control still doesn't support it, but that'll be skipped by not having a rate control ref. Since it now operates on a link sta, rename the driver method.

2024-10-22wifi: ath12k: remove msdu_end structure for WCN7850Lingbo Kong
Currently, when ath12k retrieves values from the structure rx_msdu_end_wcn7850, the information obtained is incorrect. This is because the definition of the rx_msdu_end_wcn7850 structure in ath12k is incorrect. In fact, the rx_msdu_end structure used by WCN7850 is the same as the rx_msdu_end structure of QCN9274. Commit ed823fd113b7 ("wifi: ath12k: add msdu_end structure for WCN7850") introduced this structure. The original issue trying to be fixed with that commit is that the TID information retrieved from the rx_msdu_end structure was incorrect, and it was thought that the structure wasn't correct, so a supposedly correct structure was introduced. However it was subsequently discovered that the TID information is only guaranteed to be valid in the rx_msdu_start structure, so that commit added the logic to retrieve the TID from the rx_msdu_start, but unfortunately kept the rx_msdu_end_wcn7850 structure. To address this issue, revert the code related to the rx_msdu_end_wcn7850 structure, retaining the TID retrieval logic. This patch does not affect QCN9274.

2024-10-20wifi: rtw89: wow: cast nd_config->delay to u64 in tsf arithmeticPing-Ke Shih
The type of tsf arithmetic is u64 += u16 * int; When (u16 * int) is larger than 0x7FFFFFFF, the value casting to u64 with sign-extension will become all 1 in upper 32 bits part. To meet the case, u16 value should be larger than 20491 (0x7FFFFFFF / 104800). Fortunately the meaning of 20491 is delay time of WoWLAN net detection in unit of second, so 20491 seconds (5.7 hours) might not a real case we can meet.

2024-10-16wifi: ath12k: modify link arvif creation and removal for MLOSriram R
Currently ath12k_mac_op_assign_vif_chanctx() uses ahvif->deflink to create and start vdev based on incoming channel context. With MLO multiple links could be associated to the ahvif. Use link id from link_conf passed by mac80211 and do vdev create start for intended link of ahvif. Add ath12k_mac_assign_link_vif() helper to allocate and initialize link arvif object based on input link_id. The first link arvif that is being created in an ahvif will use preallocated ahvif->deflink object and the rest gets allocated. Currently link arvif can be removed in two call backs namely ath12k_mac_op_remove_interface() and ath12k_mac_op_unassign_vif_chanctx(): * ath12k_mac_op_unassign_vif_chanctx() carries link_info so obtain link_id from link_info and handle removal for that link * ath12k_mac_op_remove_interface() is done at interface/MLD level hence loop through the active link arvifs and remove all of them Add ath12k_mac_unassign_link_vif() helper to reset/destroy the link arvifs allocated for an ahvif. For scan request from mac80211, check if the any of the link arvifs of the ahvif is already created on the radio in which scan is requested and use it. If not use deflink(link 0) for creating scan arvif. Also ath12k creates vdev during assign_vif_chanctx() mac80211 op callback as it knows channel associated with given link only in this callback. Whereas mac80211 updates addition/deletion of links to an ML vif via .change_vif_links() callback and this is done before channel assignment. Hence register an dummy ath12k_mac_op_change_vif_links() function to change_vif_links() and acknowledge mac80211s link updates.

But with MLO the incoming vif could have multiple links affiliated to it, hence use the link id provided in the key info argument and apply/cache the key to the corresponding link arvif. When the set key is a pairwise key intended for an ML station then set the same key on all the affiliated link stations. Also there could be multiple keys associates to a single link: group keys, mgmt/beacon protection keys and so on. Current key caching design lacks support for caching multiple keys for a given link cache.

With MLO, vif level config as well each link config changes inside vif needs to be updated and mac80211 uses vif_cfg_changed() and link_info_changed() callback ops for the same, this is also backward compatible where mac80211 will update default link conf changes in case VIF is non-MLO. Rename ath12k_mac_op_bss_info_changed() to ath12k_mac_op_link_info_changed() and register the same to link_info_changed callback. Register ath12k_mac_op_vif_cfg_changed() to vif_cfg_changed() callback and handle all vif level configuration changes there. Also, currently ath12k_mac_op_bss_info_changed() uses deflink to apply the config or to cache the config based on the availability of corresponding vdev. With MLO multiple links can be affiliated to a vif/BSS, so use the link id provided by mac80211 to fetch the corresponding link to which the bss change was intended.

Currently vif configuration cache pointers are placed in arvif and caching is done whenever a link vif configuration is received before driver created vdev for it (i.e. before channel is assigned), this is possible because current code only uses default link (ahvif->deflink) which is preallocated. With MLO changes the ieee80211_vif drv priv is now ahvif and its arvifs (struct ath12k_link_vif) other than deflink can be allocated dynamically during channel assignment. Hence maintain link level cache in ahvif and whenever channel is assigned for link vif and vdev is created, flush the corresponding link vif cache from ahvif. Current code uses cache of ATH12K_DEFAULT_LINK_ID (0) which is the cache of ahvif->deflink.

2024-10-16wifi: ath12k: prepare sta data structure for MLO handlingSriram R
To prepare the driver for MLO support, split the driver sta data structure to scale for multiple links. This requires changing the use of arsta to per link and not per hw which can now comprise of multiple links. Also since most configurations from mac80211 are done per link, do refactoring of the driver functions to apply these configurations at link level. Split struct ath12k_sta, which is the driver private of struct ieee80211_sta, to store link specific information as struct ath12k_link_sta. For default use cases struct ath12k_sta will have a preallocated link sta called deflink which will be used by non ML STAs and the first link sta of ML STA. With MLO support to be added, remaining link stas will allocated during state change where new STA is added. These link stas will be freed when STA is deleted. Current ath12k_sta(arsta) structure: +-----------------+ +----------------+ | | | | | ieee80211_sta | | ieee80211_sta | | private data | | private data | | | | | | ath12k_sta | | ath12k_sta | | (arsta) | | (arsta) | |+---------------+| | +-------------+| || *arvif (link || | |*arvif (link || || vif of an ar || | | vif of an ar|| || say 5GHz) || | | say 6GHz) || |+---------------+| | +-------------+| +-----------------+ +----------------+ New struct ath12k_sta (ahsta) containing ath12k_link_sta(s) (arsta) (deflink is preallocated member which is always the first link if ieee80211_sta is ML STA and is the only link sta otherwise): +---------------------------------------+ | ieee80211_sta | | private data | | | | ath12k_sta (ahsta) | | +-------------------------------------+ | | ath12k_link_sta deflink (arsta) | | | | | | *arvif (link vif of ar (5GHz)) | | +-------------------------------------+ | +-------------------------------------+ | | ath12k_link_sta *link (arsta) | | | | | | *arvif (link vif of ar (6GHz)) | | | | | +-------------------------------------+ | | +---------------------------------------+ To refactor existing ath12k_sta to make use of link stas, following changes are made: 1. Limit struct ieee80211_sta argument mac80211 ops unless otherwise really required. 2. struct ath12k_sta, now called by variable name arsta, stores multiple arstas (struct ah12k_link_sta) and also has a back pointer to struct ath12k_sta. 3. Pass struct ath12k_link_sta to mac functions that passed struct ieee80211_sta argument and fetch struct ath12k_sta (ahsta) and struct ieee80211_sta(sta) internally. This is done to avoid passing link id in all the functions and performing validation across these functions. Rather the validation and sta to arsta conversion can be done only at the mac80211 ops. 4. In this patchset, only ahsta->deflink is used to be on par with the existing code. When MLO support is added the link id will be used to fetch the arsta. 5. Change ath12k_sta_to_arsta() to ath12k_vif_to_ahsta() to fetch the ML level sta. The link sta can be fetched from ahsta->link[], or the deflink can be accessed via ahsta->deflink. API to access link sta (arsta) by passing link_id can be introduced with MLO Support. 6.
