wifi: wfx: prevent underflow in wfx_send_pds()

2022-09-02T08:44:35Z

This does a "chunk_len - 4" subtraction later when it calls: ret = wfx_hif_configuration(wdev, buf + 4, chunk_len - 4); so check for "chunk_len" is less than 4.

wifi: mac80211: replace link_id with link_conf in switch/(un)assign_vif_chanctx()

2022-07-15T09:43:20Z

Since mac80211 already has a protected pointer to link_conf, pass it to the driver to avoid additional RCU locking. Signed-off-by: Gregory Greenman Signed-off-by: Johannes Berg

wifi: mac80211: replace link_id with link_conf in start/stop_ap()

2022-07-15T09:43:17Z

When calling start/stop_ap(), mac80211 already has a protected link_conf pointer. Pass it to the driver, so it shouldn't handle RCU protection. Signed-off-by: Gregory Greenman Signed-off-by: Johannes Berg

wifi: mac80211: change QoS settings API to take link into account

2022-07-15T09:43:15Z

Take the link into account in the QoS settings (EDCA parameters) APIs. Signed-off-by: Johannes Berg

wifi: mac80211: move ps setting to vif config

2022-07-15T09:43:15Z

This really shouldn't be in a per-link config, we don't want to let anyone control it that way (if anything, link powersave could be forced through APIs to activate/deactivate a link), and we don't support powersave in software with devices that can do MLO. Signed-off-by: Johannes Berg

wifi: mac80211: return a beacon for a specific link

2022-06-20T10:57:08Z

Pass the link id through to the get_beacon and return the beacon for a specific link id. Signed-off-by: Shaul Triebitz Signed-off-by: Johannes Berg

wifi: mac80211: pass the link id in start/stop ap

2022-06-20T10:57:08Z

In start_ap and stop_ap mac80211 callbacks pass the link_id to the drivers. Signed-off-by: Shaul Triebitz Signed-off-by: Johannes Berg

wifi: mac80211: make channel context code MLO-aware

2022-06-20T10:55:15Z

Make the channel context code MLO aware, along with some functions that it uses, so that the chan.c file is now MLD-clean and no longer uses deflink/bss_conf/etc. Signed-off-by: Johannes Berg

wifi: mac80211: split bss_info_changed method

2022-06-20T10:55:09Z

Split the bss_info_changed method to vif_cfg_changed and link_info_changed, with the latter getting a link ID. Also change the 'changed' parameter to u64 already, we know we need that. Signed-off-by: Johannes Berg

wifi: mac80211: move interface config to new struct

2022-06-20T10:55:03Z

We'll use bss_conf for per-link configuration later, so move out all the non-link-specific data out into a new struct ieee80211_vif_cfg used in the vif. Some adjustments were done with the following spatch: @@ expression sdata; struct ieee80211_vif *vifp; identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator }; @@ ( -sdata->vif.bss_conf.var +sdata->vif.cfg.var | -vifp->bss_conf.var +vifp->cfg.var ) @bss_conf@ struct ieee80211_bss_conf *bss_conf; identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator }; @@ -bss_conf->var +vif_cfg->var (though more manual fixups were needed, e.g. replacing "vif_cfg->" by "vif->cfg." in many files.)
