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.

mac80211: fix scan when operating on DFS channels in ETSI domains

2019-10-07T20:10:50+00:00

In non-ETSI regulatory domains scan is blocked when operating channel
is a DFS channel. For ETSI, however, once DFS channel is marked as
available after the CAC, this channel will remain available (for some
time) even after leaving this channel.

Therefore a scan can be done without any impact on the availability
of the DFS channel as no new CAC is required after the scan.

Enable scan in mac80211 in these cases.

cfg80211: initialize on-stack chandefs

2019-10-01T15:56:18+00:00

In a few places we don't properly initialize on-stack chandefs,
resulting in EDMG data to be non-zero, which broke things.

Additionally, in a few places we rely on the driver to init the
data completely, but perhaps we shouldn't as non-EDMG drivers
may not initialize the EDMG data, also initialize it there.
