Johannes Berg 3a5a423bb9 nl80211: fix attrbuf access race by allocating a separate one ... Since my commit 3713b4e364 ("nl80211: allow splitting wiphy information in dumps"), nl80211_dump_wiphy() uses the global nl80211_fam.attrbuf for parsing the incoming data. This wouldn't be a problem if it only did so on the first dump iteration which is locked against other commands in generic netlink, but due to space constraints in cb->args (the needed state doesn't fit) I decided to always parse the original message. That's racy though since nl80211_fam.attrbuf could be used by some other parsing in generic netlink concurrently. For now, fix this by allocating a separate parse buffer (it's a bit too big for the stack, currently 1448 bytes on 64-bit). For -next, I'll change the code to parse into the global buffer in the first round only and then allocate a smaller buffer to keep the data in cb->args.
