2014-05-06iwlwifi: mvm: rs: revert changes to search cycle rulesEyal Shapira
Adding more options in the search cycle causes longer search cycles with additional wondering off to non optimal Tx configurations. Reduce the Tx configurations searched to improve throughput in non optimal attenuations.

2014-04-30wlcore: fix usage of platform_device_add_data()Christian Engelmayer
Coverity CID 986698 reports leakage of struct wlcore_platdev_data in the probe functions of both the SPI/SDIO interfaces. The structure passed to platform_device_add_data() is dynamically allocated and only freed in the error paths, however, platform_device_add_data() adds a copy of the platform specific data to the device. Move the temporary struct that is kmemdup'ed to the stack. This issue exists since afb43e6d (wlcore: remove if_ops from platform_data).

94010fa0dd07e8b904e7c6b6589f15573008ab15 ("rtlwifi: add MSI interrupts mode support") introduced MSI interrupts mode support, which seemed safe enough with RTL8188EE and RTL8723BE as RealTek's testing results, but some users reported their RTL8188EE modules could not connect to any wireless network after the MSI mode was enabled by Ubuntu 14.04.

2014-04-28cfg80211: Dynamic channel bandwidth changes in AP modeJouni Malinen
This extends NL80211_CMD_SET_CHANNEL to allow dynamic channel bandwidth changes in AP mode (including P2P GO) during a lifetime of the BSS.

2014-04-28mac80211: remove unnecessary assignmentZhao, Gang
P2P_DEVICE doesn't support ieee80211_bss_info_change_notify() for now, so it's not needed to set changed flags for P2P_DEVICE. Signed-off-by: Zhao, Gang <gamerh2o@gmail.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-04-28mac80211: avoid calling useless channel context codeZhao, Gang
ieee80211_assign_chanctx() checks if local->use_chanctx is true, so the two code block related to ieee80211_assign_chanctx() can be moved into above if clause, emphasize that these code are executed only if local->use_chanctx is true.

2014-04-25cfg80211: Use 5MHz bandwidth by default when checking usable channelsRostislav Lisovy
Current code checks if the 20MHz bandwidth is allowed for particular channel -- if it is not, the channel is disabled. Since we need to use 5/10 MHz channels, this code is modified in the way that the default bandwidth to check is 5MHz. If the maximum bandwidth allowed by the channel is smaller than 5MHz, the channel is disabled. Otherwise the channel is used and the flags are set according to the bandwidth allowed by the channel.

2014-04-25cfg80211: Add attributes describing prohibited channel bandwidthRostislav Lisovy
Since there are frequency bands (e.g. 5.9GHz) allowing channels with only 10 or 5 MHz bandwidth, this patch adds attributes that allow keeping track about this information. When channel attributes are reported to user-space, make sure to not break old tools, i.e. if the 'split wiphy dump' is enabled, report the extra attributes (if present) describing the bandwidth restrictions. If the 'split wiphy dump' is not enabled, completely omit those channels that have flags set to either IEEE80211_CHAN_NO_10MHZ or IEEE80211_CHAN_NO_20MHZ. Add the check for new bandwidth restriction flags in cfg80211_chandef_usable() to comply with the restrictions.

2014-04-25cfg80211: change wiphy_to_dev function nameZhao, Gang

2014-04-25cfg80211: change registered device pointer nameZhao, Gang
Name "dev" is too common and ambiguous, let all the pointer name pointing to struct cfg80211_registered_device be "rdev".

2014-04-25mac80211: compute chanctx refcount on-the-flyMichal Kazior
It doesn't make much sense to store refcount in the chanctx structure. One still needs to hold chanctx_mtx to get the value safely. Besides, refcount isn't on performance critical paths. This will make implementing chanctx reservation refcounting a little easier. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-04-25mac80211: fix racy usage of chanctx->refcountMichal Kazior
Channel context refcount is protected by chanctx_mtx. Accessing the value without holding the mutex is racy. RCU section didn't guarantee anything here. Theoretically ieee80211_channel_switch() could fail to see refcount change and read "1" instead of, e.g. "2". This means mac80211 could accept CSA even though it shouldn't have.

2014-04-25mac80211: improve chanctx reservation lookupMichal Kazior
Use a separate function to look for reservation chanctx. For multi-interface/channel reservation search sematics differ slightly.

2014-04-25mac80211: improve find_chanctx() for reservationsMichal Kazior
This allows new vifs to be assigned to a chanctx as long as chanctx's reservation chandefs (if any) and chanctx's current chandef (implied by assigned vifs at the time, if any) and the new vif chandef are all compatible. This implies it is impossible to assign a new vif to an in-place reservation chanctx. This gives no advantages for single-channel hardware. It makes sense for multi-channel hardware only.

2014-04-25mac80211: prevent chanctx overcommitMichal Kazior
Do not allocate more channel contexts than a driver is capable for currently matching interface combination. This allows the ieee80211_vif_reserve_chanctx() to act as a guard against breaking interface combinations.

2014-04-25cfg80211: allow drivers to iterate over matching combinationsMichal Kazior
The patch splits cfg80211_check_combinations() into an iterator function and a simple iteration user. This makes it possible for drivers to asses how many channels can use given iftype setup. This in turn can be used for future multi-interface/multi-channel channel switching. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-04-25cfg80211: Fix GO Concurrent relaxation on UNII-3Ilan Peer
At some locations, channels 149-165 are considered a single bundle, while at some other locations, e.g., Indonesia, channels 149-161 are considered a single bundle, while channel 165 belongs to a different bundle. This means that: 1. A station interface connection to an AP on channel 165 allows the instantiation of a P2P GO on channels 149-165. 2. A station interface connection to an AP on channels 149-161 does NOT allow the instantiation of a P2P GO on channel 165. Fix this.
