wifi: cfg80211: use ML element parsing helpers

2024-02-21T14:19:04+00:00

Use the existing ML element parsing helpers and add a new
one for this (ieee80211_mle_get_mld_id).

wifi: mac80211: align ieee80211_mle_get_bss_param_ch_cnt()

2024-02-21T14:19:04+00:00

Align the prototype of ieee80211_mle_get_bss_param_ch_cnt()
to also take a u8 * like the other functions, and make it
return -1 when the field isn't found, so that mac80211 can
check that instead of explicitly open-coding the check.

wifi: mac80211: adjust EHT capa when lowering bandwidth

2024-02-08T14:00:43+00:00

If intending to associate with a lower bandwidth, remove capabilities
related to 320 MHz from the EHT capabilities element. Also change the
EHT MCS-NSS set accordingly: if just reducing 320->160 or similar the
format doesn't change, just cut off the last bytes. If changing from
higher bandwidth to 20 MHz only EHT STA, adjust the format.

Note that this also requires adjusting the caller in mlme.c since the
data written can now be shorter than it determined. We need to clean
all that up. Since the other callers pass NULL for the conn limit, we
don't need to change things there.

wifi: mac80211: implement MLO multicast deduplication

2024-02-08T14:00:42+00:00

If the vif is an MLD then it may receive multicast from
different links, and should drop those frames according
to the SN. Implement that.

wifi: mac80211: add/use ieee80211_get_sn()

2024-02-08T14:00:42+00:00

This will also be useful for MLO duplicate multicast
detection, but add it already here and use it in one
place that trivially converts.

wifi: mac80211: refactor puncturing bitmap extraction

2024-02-08T12:07:37+00:00

Add a new inline helper function to ieee80211.h to
extract the disabled subchannels bitmap from an EHT
operation element, and use that in mac80211 where
we do that.

wifi: cfg80211: validate MLO connections better

2024-01-26T08:39:49+00:00

When going into an MLO connection, validate that the link IDs
match what userspace indicated, and that the AP MLD addresses
and capabilities are all matching between the links.

====================
wireless-next patches for v6.8

The third "new features" pull request for v6.8. This is a smaller one
to clear up our tree before the break and nothing really noteworthy
this time.

Major changes:

stack

* cfg80211: introduce cfg80211_ssid_eq() for SSID matching

* cfg80211: support P2P operation on DFS channels

* mac80211: allow 64-bit radiotap timestamps

iwlwifi

* AX210: allow concurrent P2P operation on DFS channels
