Merge tag 'mac80211-for-davem-2018-02-22' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says: ==================== Various fixes across the tree, the shortlog basically says it all: cfg80211: fix cfg80211_beacon_dup -> old bug in this code cfg80211: clear wep keys after disconnection -> certain ways of disconnecting left the keys mac80211: round IEEE80211_TX_STATUS_HEADROOM up to multiple of 4 -> alignment issues with using 14 bytes mac80211: Do not disconnect on invalid operating class -> if the AP has a bogus operating class, let it be mac80211: Fix sending ADDBA response for an ongoing session -> don't send the same frame twice cfg80211: use only 1Mbps for basic rates in mesh -> interop issue with old versions of our code mac80211_hwsim: don't use WQ_MEM_RECLAIM -> it causes splats because it flushes work on a non-reclaim WQ regulatory: add NUL to request alpha2 -> nla_put_string() issue from Kees mac80211: mesh: fix wrong mesh TTL offset calculation -> protocol issue mac80211: fix a possible leak of station stats -> error path might leak memory mac80211: fix calling sleeping function in atomic context -> percpu allocations need to be made with gfp flags ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
