wifi: mac80211: convert debugfs files to short fops

2024-10-23T14:47:07+00:00

Given the large size of the regular struct file_operations, save a lot of space with the newly added short fops for debugfs. Link: https://patch.msgid.link/20241022151838.2f6de3ea3ecc.I45657e6a8415d796ec95c95becc9efb377ee3be6@changeid Signed-off-by: Johannes Berg

wifi: mac80211: call rate_control_rate_update() for link STA

2024-10-23T14:43:27+00:00

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.

wifi: mac80211: allow rate_control_rate_init() for links

2024-10-23T14:43:23+00:00

Andrei previously fixed an issue in the client where the NSS for links other than the primary/assoc/deflink isn't set. The same issue appears to exist on the AP side, because there's only a call to rate_control_rate_init() for the deflink, and not any other links. Rework the code a bit to do rate_control_rate_init() for links, even if it really doesn't work with software rate control yet, it does other things as well. Also add rate_control_rate_init_all_links() to actually do it properly when moving to ASSOC state in cfg80211. Change the explicit call to ieee80211_sta_init_nss() to instead be rate_control_rate_init() now in the client code, but also add a call to rate_control_rate_init() when a link is added in AP mode and the STA is already associated. This should fix the NSS initialization issue, and perhaps pave the way for actual software rate scaling a bit, in case anyone cares in the future, but that of course needs a lot more than just the init call. We still need to fix the rate control _update_ as well, and the sta_rc_update() driver method especially, but that will be in a different patch.

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.

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
