2009-01-29mac80211: Fix radiotap header it_present on big endian CPUsJouni Malinen
When the IEEE80211_RADIOTAP_RATE flag was moved to be conditional, it was mistakenly left without cpu_to_le32(). Fix that. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-01-29mac80211: Handle power constraint level advertised in 11d+h beaconVasanthakumar Thiagarajan

2009-01-29mac80211: 802.11w - Add driver capability flag for MFPJouni Malinen

2009-01-29mac80211: 802.11w - Optional software CCMP for management framesJouni Malinen
If driver/firmware/hardware does not support CCMP for management frames, it can now request mac80211 to take care of encrypting and decrypting management frames (when MFP is enabled) in software. The will need to add this new IEEE80211_KEY_FLAG_SW_MGMT flag when a CCMP key is being configured for TX side and return the undecrypted frames on RX side without RX_FLAG_DECRYPTED flag to use software CCMP for management frames (but hardware for data frames).

2009-01-29mac80211: 802.11w - Implement Association Comeback processingJouni Malinen
When MFP is enabled, the AP does not allow a STA to associate if an existing security association exists without first going through SA Query process. When this happens, the association request is denied with a new status code ("temporarily rejected") ans Association Comeback IE is used to notify when the association may be tried again (i.e., when the SA Query procedure has timed out). Use the comeback time to update the mac80211 client MLME timer for next association attempt to minimize waiting time if association is temporarily rejected.

Implement Broadcast/Multicast Integrity Protocol for management frame protection. This patch adds the needed definitions for the new information element (MMIE) and implementation for the new "encryption" type (though, BIP is actually not encrypting data, it provides only integrity protection).

2009-01-29cfg80211: allow multiple driver regulatory_hints()Luis R. Rodriguez
We add support for multiple drivers to provide a regulatory_hint() on a system by adding a wiphy specific regulatory domain cache. This allows drivers to keep around cache their own regulatory domain structure queried from CRDA. We handle conflicts by intersecting multiple regulatory domains, each driver will stick to its own regulatory domain though unless a country IE has been received and processed. If the user already requested a regulatory domain and a driver requests the same regulatory domain then simply copy to the driver's regd the same regulatory domain and do not call CRDA, do not collect $200.

2009-01-29mac80211: clean up channel type configJohannes Berg
The channel_type really doesn't need to be the only member in a new structure, so remove the struct. Additionally, remove the _CONF_CHANGE_HT flag and use _CONF_CHANGE_CHANNEL when the channel type changes, since that's enough of a change to require reprogramming the hardware anyway.

2009-01-29mac80211: clarify alignment docs, fix up alignmentJohannes Berg
Not all drivers are capable of passing properly aligned frames, in particular with mesh networking no hardware will support completely aligning it correctly.

2009-01-29mac80211: Don't merge if BSSID is set manuallyAlina Friedrichsen

2009-01-29mac80211: Disallow to set multicast BSSIDAlina Friedrichsen
Okay, here is the first of the five patches. After applying all of them you should be able to build/join huge city mesh networks (e.g. with the OLSR protocol) with the most of the mac80211 wireless drivers by setting a fixed BSSID in the ad hoc mode. (If you found no other bug/problem.) This was not specified in the original standard, but is a widely used de facto standard.

2009-01-29mac80211: Fix tx power settingVasanthakumar Thiagarajan
power_level in ieee80211_conf is being used for more than one purpose. It being used as user configured power limit and the final power limit given to the driver. By doing so, except very first time, the tx power limit is taken from min(chan->max_power, local->hw.conf.power_level) which is not what we want.

2009-01-29mac80211: Reset the power save timer from master_start_xmit.Vivek Natarajan
When a null data frame is generated from mac80211, it goes through master_start_xmit and not through subif_start_xmit. Hence for the power save timer to be triggered while sending this null data frame also, the timer has to be reset from master_start_xmit.

2009-01-29mac80211: Scale down to non-HT association with TKIP/WEP as pairwise cipherVasanthakumar Thiagarajan
As TKIP is not updated to new security needs which arise when TKIP is used to encrypt A-MPDU aggregated data frames, IEEE802.11n does not allow any cipher other than CCMP (Which has new extensions defined) as pairwise cipher between HT peers. When such configuration (TKIP/WEP in HT) is forced, we still associate in non-HT mode (11a/b/g).
