-Subject: [PATCH] mac80211: initialize fast-xmit 'info' later
-
-In ieee80211_xmit_fast(), 'info' is initialized to point to the skb
-that's passed in, but that skb may later be replaced by a clone (if
-it was shared), leading to an invalid pointer.
-
-This can lead to use-after-free and also later crashes since the
-real SKB's info->hw_queue doesn't get initialized properly.
-
-Fix this by assigning info only later, when it's needed, after the
-skb replacement (may have) happened.
