2011-11-11iwlagn: fix NULL ptr deref when reprogramming sta w/o LQJohannes Berg
Reinette reports a crash in iwl_reprogram_ap_sta(). The debugging shows: b1 16 mov $0x16,%cl *f3 a5 rep movsl %ds <-- trapping instruction:(%rsi),%es:(%rdi) which is a memcpy of 22 (0x16) words (movsl). this points to "priv->stations[sta_id].lq" being NULL since that is the memcpy() of that size here. The only way I see for this to happen is if we try to do some RXON reprogramming while connecting to an AP, after tx_sync() but before full setup, but that seems like something that might very well happen. Fix this by checking if the LQ is present and only then reprogramming it.

2011-11-11iwlwifi: Suppress noisy syslog messages when RF_KILL switch engagedTodd Previte
When a station is associated with an AP and the RF_KILL switch is engaged, numerous error messages were sent to the system log. The error messages were the result of the failure(s) of the various submodules to perform their tasks after the radios were disabled. To resolve this situation, the messages were modified to use a new macro, IWL_DEBUG_QUIET_RFKILL. This macro allows for the RF_KILL error messages to be sent to the log provided that IWL_DEBUG is true and IWL_DL_RADIO is '1'. For all other cases, the error messages resulting from an RFKILL event will not be sent to the system log. Messages logged because of an RFKILL will be tagged with the prefix '(RFKILL)' to clarify the cause of the error.

2011-11-11iwlagn: add P2P NoA to probe responsesJohannes Berg
Whether to use NoA or not is entire controlled by the uCode right now, and it also adds the attribute to beacons. We do need to add it to probe responses in the driver though. Keep track of the NoA notification from the uCode and add the data to probe responses when such are transmitted. Use RCU to manage the lifetime.

2011-11-11nl80211: fix compiler warningJohannes Berg
John reported the following warning: net/wireless/nl80211.c: In function ‘nl80211_tx_mgmt’: net/wireless/nl80211.c:5286:8: warning: ‘hdr’ may be used uninitialized in this function Evidently, his version of gcc isn't able to see that when "msg" is initialized, "hdr" must also be. My gcc, 4.6.1, can actually see that and doesn't warn. Simply initialize the variable to NULL. That means if the compiler was ever right we'll crash though so isn't really optimal since it may hide warnings from the compiler when somebody modifies this code in the future.

2011-11-11mwifiex: remove unnecessary free_priv handlerAmitkumar Karwar
Cfg80211 stack allocates private area for driver use in struct cfg80211_bss. It will be freed by stack in bss_release(). Driver don't need to worry about it. In mwifiex driver, we use the private area just to store band information(u8). We don't allocate memory explicitly and store it's pointer in bss->priv. Hence we don't have any cleanup work to do in free_priv handler. Currently we try to free the allocated private area in free_priv handler which is not correct.

2011-11-11cfg80211: merge in beacon ies of hidden bss.Dmitry Tarnyagin
The problem with PSM when a hidden SSID was used was originally reported by Juuso Oikarinen. - When generally scanning, the AP is getting a bss entry with a zero SSID. - When associating, a probe-req is sent to the AP with the SSID, and as a result a probe-response is received with the hidden SSID in place. As a consequence, a second bss entry is created for the AP, now with the real SSID. - After association, mac80211 executes ieee80211_recalc_ps(), but does not switch to powersave because the beacon-ies are missing. As result, the STA does not ever enter PSM. The patch merges in beacon ies of hidden bss from beacon to the probe response, creating a consistent set of ies in place.
