* ssb: do not read SPROM if it does not existJohn W. Linville2010-04-265-0/+39
| | | | | | | | | | | | | | | | | | | Attempting to read registers that don't exist on the SSB bus can cause hangs on some boxes. At least some b43 devices are 'in the wild' that don't have SPROMs at all. When the SSB bus support loads, it attempts to read these (non-existant) SPROMs and causes hard hangs on the box -- no console output, etc. This patch adds some intelligence to determine whether or not the SPROM is present before attempting to read it. This avoids those hard hangs on those devices with no SPROM attached to their SSB bus. The SSB-attached devices (e.g. b43, et al.) won't work, but at least the box will survive to test further patches. :-) Signed-off-by: John W.

* mac80211: Fix ieee80211_sta_conn_mon_timer with hw connection monitoringJuuso Oikarinen2010-04-201-0/+5
| | | | | | | | | | | | | | | | When IEEE80211_HW_CONNECTION_MONITOR is configured by the driver, starting of ieee80211_sta_conn_mon_timer should be prevented, as it is then not needed. This is currently partially the case. As it seems, when a probe-response is received from the AP the timer is still restarted, thus restarting the host based connection keep-alive mechanism. These probe-responses happen at least when scanning while associated. Fix this by preventing starting of the ieee80211_sta_conn_mon_timer in the ieee80211_rx_mgmt_probe_resp function.

* ath9k: Group Key fix for VAPsDaniel Yingqiang Ma2010-04-203-3/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | When I set up multiple VAPs with ath9k, I encountered an issue that the traffic may be lost after a while. The detailed phenomenon is 1. After a while the clients connected to one of these VAPs will get into a state that no broadcast/multicast packets can be transfered successfully while the unicast packets can be transfered normally. 2. Minutes latter the unitcast packets transfer will fail as well, because the ARP entry is expired and it can't be freshed due to the broadcast trouble. It's caused by the group key overwritten and someone discussed this issue in ath9k-devel maillist before, but haven't work out a fix yet. I referred the method in madwifi, and made a patch for ath9k. The method is to set the high bit of the sender(AP)'s address, and associated that mac and the group key. It requires the hardware supports multicast frame key search. It seems true for AR9160. Not sure whether it's the correct way to fix this issue. But it seems to work in my test. The patch is attached, feel free to revise it.
