mac80211: convert S1G beacon to scan results

2020-09-28T11:53:25+00:00

This commit finds the correct offset for Information Elements in S1G beacon frames so they can be reported in scan results. Signed-off-by: Thomas Pedersen Link: https://lore.kernel.org/r/20200922022818.15855-8-thomas@adapt-ip.com Signed-off-by: Johannes Berg

mac80211: s1g: choose scanning width based on frequency

2020-09-28T11:53:05+00:00

An S1G BSS can beacon at either 1 or 2 MHz and the channel width is unique to a given frequency. Ignore scan channel width for now and use the allowed channel width.

nl80211/cfg80211: support 6 GHz scanning

2020-09-28T11:53:04+00:00

Support 6 GHz scanning, by * a new scan flag to scan for colocated BSSes advertised by (and found) APs on 2.4 & 5 GHz * doing the necessary reduced neighbor report parsing for this, to find them * adding the ability to split the scan request in case the device by itself cannot support this. Also add some necessary bits in mac80211 to not break with these changes.

mac80211: remove unused flags argument in transmit functions

The flags argument in transmit functions is no longer being used and can be removed. Signed-off-by: Mathy Vanhoef Link: https://lore.kernel.org/r/20200723100153.31631-5-Mathy.Vanhoef@kuleuven.be Signed-off-by: Johannes Berg

mac80211: use same flag everywhere to avoid sequence number overwrite

2020-07-31T07:27:01+00:00

Use the IEEE80211_TX_CTRL_NO_SEQNO flag in ieee80211_tx_info to mark probe requests whose sequence number must not be overwritten. This provides consistency with the radiotap flag that can be set to indicate that the sequence number of an injected frame should not be overwritten.

mac80211: avoid using ext NSS high BW if not supported

2020-05-31T09:26:50+00:00

If the AP advertises inconsistent data, namely it has CCFS1 or CCFS2, but doesn't advertise support for 160/80+80 bandwidth or "Extended NSS BW Support", then we cannot use any MCSes in the the higher bandwidth. Thus, avoid connecting with higher bandwidth since it's less efficient that way.

mac80211: add freq_offset to RX status

2020-04-24T10:33:43+00:00

RX status needs a KHz component, so add freq_offset. We can reduce the bits for the frequency since 60 GHz isn't supported. Signed-off-by: Thomas Pedersen Link: https://lore.kernel.org/r/20200402011810.22947-5-thomas@adapt-ip.com [fix commit message] Signed-off-by: Johannes Berg

mac80211: handle channel frequency offset

2020-04-24T10:33:43+00:00

cfg80211_chan_def and ieee80211_channel recently gained a frequency offset component. Handle this where it makes sense (potentially required by S1G channels). For IBSS, TDLS, CSA, and ROC we return -EOPNOTSUPP if a channel with frequency offset is passed, since they may or may not work. Once someone tests and verifies these commands work on thos types of channels, we can remove that error. join_ocb and join_mesh look harmless because they use a simple ieee80211_vif_use_channel(), which is using an already verified channel, so we let those through.
