mac80211: fix NULL ptr dereference during mesh peer connection for non HE devices

2021-06-23T16:06:44+00:00

"sband->iftype_data" is not assigned with any value for non HE supported devices, which causes NULL pointer access during mesh peer connection in those devices. Fix this by accessing the pointer after HE capabilities condition check.

mac80211: remove use of ieee80211_get_he_sta_cap()

2021-06-23T09:33:26+00:00

All uses of ieee80211_get_he_sta_cap() were actually wrong, in net/mac80211/mlme.c they were wrong because that code is also used for P2P (which is a different interface type), in net/mac80211/main.c that should check all interface types. Fix all that.

mac80211: reduce peer HE MCS/NSS to own capabilities

2021-01-22T08:11:28+00:00

For VHT capbility, we do intersection of MCS and NSS for peers in mac80211, to simplify drivers. Add this for HE as well.

mac80211: use HE 6 GHz band capability and pass it to the driver

2020-05-31T09:27:03+00:00

In order to handle 6 GHz AP side, take the HE 6 GHz band capability data and pass it to the driver (which needs it for A-MPDU spacing and A-MPDU length).

mac80211: fix memory overlap due to variable length param

2020-04-29T14:21:45+00:00

As of now HE operation element in bss_conf includes variable length optional field followed by other HE variable. Though the optional field never be used, actually it is referring to next member of the bss_conf structure which is not correct. Fix it by declaring needed HE operation fields within bss_conf itself.

mac80211: Handle SMPS mode changes only in AP mode

2020-02-07T11:47:30+00:00

According to IEEE802.11 specifications the SM power save field in the HT capability IE and the HE extended capability IE is valid only in (re)association frames and should be ignored otherwise. Remove code paths that handled this also for non AP modes.
