Subject[PATCH 0/7] wifi: cfg80211: Annotate with __counted_by
Date
Hi,

This annotates several structures with the coming __counted_by attribute
for bounds checking of flexible arrays at run-time. As a note toward
applicability, had this mitigation been available already, the flaw
fixed in commit 6311071a0562 ("wifi: nl80211: fix integer overflow in
nl80211_parse_mbssid_elems()") would have already been unexploitable
(i.e. writes through an out-of-bounds index would have been blocked).

Thanks!
