Summary
wifi: mac80211: fix potential key use-after-free
Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: fix potential key use-after-free

When ieee80211keylink() is called by ieee80211gtkrekeyadd() but returns 0 due to KRACK protection (identical key reinstall), ieee80211gtkrekeyadd() will still return a pointer into the key, in a potential use-after-free. This normally doesn't happen since it's only called by iwlwifi in case of WoWLAN rekey offload which has its own KRACK protection, but still better to fix, do that by returning an error code and converting that to success on the cfg80211 boundary only, leaving the error for bad callers of ieee80211gtkrekey_add().
