wifi: mac80211: add support for mld in ieee80211_chswitch_done

2023-09-11T10:31:31+00:00

This allows to finalize the CSA per link.
In case the switch didn't work, tear down the MLD connection.
Also pass the ieee80211_bss_conf to post_channel_switch to let the
driver know which link completed the switch.

wifi: mac80211: Replace strlcpy with strscpy

2023-06-14T10:32:19+00:00

strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().

Direct replacement is safe here since LOCAL_ASSIGN is only used by
TRACE macros and the return values are ignored.

wifi: mac80211: include key action/command in tracing

2023-06-14T10:20:07+00:00

We trace the key information and all, but not whether the key
is added or removed - add that information.

wifi: mac80211: fix min center freq offset tracing

2023-05-16T17:18:06+00:00

We need to set the correct trace variable, otherwise we're
overwriting something else instead and the right one that
we print later is not initialized.

wifi: mac80211: add flush_sta method

2023-04-13T14:32:31+00:00

Some drivers like iwlwifi might have per-STA queues, so we
may want to flush/drop just those queues rather than all
when removing a station. Add a separate method for that.

wifi: mac80211: add support for letting drivers register tc offload support

2023-03-22T12:20:03+00:00

On newer MediaTek SoCs (e.g. MT7986), WLAN->WLAN or WLAN->Ethernet flows can
be offloaded by the SoC. In order to support that, the .ndo_setup_tc op is
needed.

wifi: mac80211: remove link_id parameter from link_info_changed()

2022-07-15T09:43:20+00:00

Since struct ieee80211_bss_conf already contains link_id,
passing link_id is not necessary.

Since mac80211 already has a protected pointer to link_conf,
pass it to the driver to avoid additional RCU locking.

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

2022-07-15T09:43:17+00:00

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.
