wifi: mac80211: make ieee80211_check_rate_mask() link-aware

2022-07-15T09:43:21+00:00

Change ieee80211_check_rate_mask() to use a link rather than the sdata and deflink/bss_conf. Signed-off-by: Johannes Berg

wifi: mac80211: status: look up band only where needed

2022-06-20T10:55:38+00:00

For MLD, we might eventually not really know the band on status, but some code assumes it's there. Move the sband lookup deep to the code that actually needs it, to make it clear where exactly it's needed and for what purposes. For rate control, at least initially we won't support it in MLO, so that won't be an issue. For TX monitoring, we may have to elide the rate and/or rely on ieee80211_tx_status_ext() for rate information. This also simplifies the function prototypes. Signed-off-by: Johannes Berg

wifi: mac80211: make channel context code MLO-aware

2022-06-20T10:55:15+00:00

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

mac80211: populate debugfs only after cfg80211 init

2020-04-24T09:30:13+00:00

When fixing the initialization race, we neglected to account for the fact that debugfs is initialized in wiphy_register(), and some debugfs things went missing (or rather were rerooted to the global debugfs root). Fix this by adding debugfs entries only after wiphy_register(). This requires some changes in the rate control code since it currently adds debugfs at alloc time, which can no longer be done after the reordering.

mac80211: remove unused and unneeded remove_sta_debugfs callback

2019-07-26T11:21:12+00:00

The remove_sta_debugfs callback in struct rate_control_ops is no longer used by any driver, as there is no need for it (the debugfs directory is already removed recursivly by the mac80211 core.) Because no one needs it, just remove it to keep anyone else from accidentally using it in the future. Cc: Johannes Berg Cc: "David S.

mac80211: minstrel: merge with minstrel_ht, always enable VHT support

2018-10-11T14:01:01+00:00

Legacy-only devices are not very common and the overhead of the extra code for HT and VHT rates is not big enough to justify all those extra lines of code to make it optional. Signed-off-by: Felix Fietkau Signed-off-by: Johannes Berg

mac80211: make rate control tx status API more extensible

2017-04-28T08:57:33+00:00

Rename .tx_status_noskb to .tx_status_ext and pass a new on-stack struct ieee80211_tx_status instead of struct ieee80211_tx_info. This struct can be used to pass extra information, e.g. for dynamic tx power control Signed-off-by: Felix Fietkau Signed-off-by: Johannes Berg

mac80211: reject/clear user rate mask if not usable

2017-03-08T13:20:01+00:00

If the user rate mask results in no (basic) rates being usable, clear it. Also, if we're already operating when it's set, reject it instead. Technically, selecting basic rates as the criterion is a bit too restrictive, but calculating the usable rates over all stations (e.g. in AP mode) is harder, and all stations must support the basic rates. Similarly, in client mode, the basic rates will be used anyway for control frames. This fixes the "no supported rates (...) in rate_mask ..." warning that occurs on TX when you've selected a rate mask that's not compatible with the connection (e.g. an AP that enables only the rates 36, 48, 54 and you've selected only 6, 9, 12.)
