Merge tag 'mac80211-for-davem-2019-10-08' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211

Johannes Berg says:

====================
A number of fixes:
 * allow scanning when operating on radar channels in
   ETSI regdomains
 * accept deauth frames in IBSS - we have code to parse
   and handle them, but were dropping them early
 * fix an allocation failure path in hwsim
 * fix a failure path memory leak in nl80211 FTM code
 * fix RCU handling & locking in multi-BSSID parsing
 * reject malformed SSID in mac80211 (this shouldn't
   really be able to happen, but defense in depth)
 * avoid userspace buffer overrun in ancient wext code
   if SSID was too long
====================
