Johannes Berg 667503ddcb cfg80211: fix locking ... Over time, a lot of locking issues have crept into the smarts of cfg80211, so e.g. scan completion can race against a new scan, IBSS join can race against leaving an IBSS, etc. Introduce a new per-interface lock that protects most of the per-interface data that we need to keep track of, and sprinkle assertions about that lock everywhere. Some things now need to be offloaded to work structs so that we don't require being able to sleep in functions the drivers call. The exception to that are the MLME callbacks (rx_auth etc.) that currently only mac80211 calls because it was easier to do that there instead of in cfg80211, and future drivers implementing those calls will, if they ever exist, probably need to use a similar scheme like mac80211 anyway... In order to be able to handle _deauth and _disassoc properly, introduce a cookie passed to it that will determine locking requirements.
