mac80211: be more careful in suspend/resume 2011-07-15T17:39:42+00:00 Johannes Berg johannes.berg@intel.com 2011-07-14T14:48:54+00:00 94f9b97be5b3bf67392e43fb7f567721b09142c2 When suspending with all netdevs down, the device is stopped but we still call a number of driver callbacks that the driver might not expect. The same happens during resume, we might call a few callbacks without starting the driver. Fix this by checking open_count around more things and exiting quickly if it is 0. Also, while at this I noticed that the coverage class isn't reprogrammed after resume, so add that. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

mac80211: allow driver to disconnect after resume 2011-07-13T18:49:43+00:00 Johannes Berg johannes.berg@intel.com 2011-07-12T10:30:59+00:00 95acac61ba66c4abd40e038dae8c1ed2e176c7b1 In WoWLAN, devices may use crypto keys for TX/RX and could also implement GTK rekeying. If the driver isn't able to retrieve replay counters and similar information from the device upon resume, or if the device isn't responsive due to platform issues, it isn't safe to keep the connection up as GTK rekey messages from during the sleep time could be replayed against it. The only protection against that is disconnecting from the AP. Modifying mac80211 to do that while it is resuming would be very complex and invasive in the case that the driver requires a reconfig, so do it after it has resumed completely. In that case, however, packets might be replayed since it can then only happen after TX/RX are up again, so mark keys for interfaces that need to disconnect as "tainted" and drop all packets that are sent or received with those keys.
