cfg80211: regulatory: reject invalid hints

2020-08-27T08:53:14+00:00

Reject invalid hints early in order to not cause a kernel
WARN later if they're restored to or similar.

cfg80211: express channels with a KHz component

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

Some bands (S1G) define channels centered on a non-integer
MHz. Give ieee80211_channel and cfg80211_chan_def a
freq_offset component where the final frequency can be
expressed as:

MHZ_TO_KHZ(chan->center_freq) + chan->freq_offset;

Also provide some helper functions to do the frequency
conversion and test for equality.

Retain the existing interface to frequency and channel
conversion helpers, and expose new ones which handle
frequencies in units of KHz.

Some internal functions (net/wireless/chan.c) pass around
a frequency value. Convert these to units of KHz.

mesh, ibss, wext, etc. are currently ignored.

cfg80211: check reg_rule for NULL in handle_channel_custom()

2020-02-21T09:59:27+00:00

We may end up with a NULL reg_rule after the loop in
handle_channel_custom() if the bandwidth didn't fit,
check if this is the case and bail out if so.

Johannes Berg says:

====================
A few big new things:
 * 802.11 frame encapsulation offload support
 * more HE (802.11ax) support, including some for 6 GHz band
 * powersave in hwsim, for better testing

Of course as usual there are various cleanups and small fixes.

cfg80211: add no HE indication to the channel flag

2020-02-07T11:34:09+00:00

The regulatory domain might forbid HE operation.  Certain regulatory
domains may restrict it for specific channels whereas others may do it
for the whole regulatory domain.

Add an option to indicate it in the channel flag.

cfg80211: Fix radar event during another phy CAC

2020-01-15T08:50:48+00:00

In case a radar event of CAC_FINISHED or RADAR_DETECTED
happens during another phy is during CAC we might need
to cancel that CAC.

If we got a radar in a channel that another phy is now
doing CAC on then the CAC should be canceled there.

If, for example, 2 phys doing CAC on the same channels,
or on comptable channels, once on of them will finish his
CAC the other might need to cancel his CAC, since it is no
longer relevant.

To fix that the commit adds an callback and implement it in
mac80211 to end CAC.
This commit also adds a call to said callback if after a radar
event we see the CAC is no longer relevant

wireless: fix enabling channel 12 for custom regulatory domain

2020-01-15T08:47:52+00:00

Commit e33e2241e272 ("Revert "cfg80211: Use 5MHz bandwidth by
default when checking usable channels"") fixed a broken
regulatory (leaving channel 12 open for AP where not permitted).
Apply a similar fix to custom regulatory domain processing.
