2014-10-14lib80211: remove unused print_ssid()Andy Shevchenko
In kernel we have %*pE specifier to print an escaped buffer. All users now switched to that approach. This fixes a bug as well. The current implementation wrongly prints octal numbers: only two first digits are used in case when 3 are required and the rest of the string ends up cut off. Additionally by default the \f, \v, \a, and \e are escaped to their alphabetic representation. It's safe to do since it is currently used for messaging only.

2014-10-09nl80211: sanity check the channel switch counter valueLuciano Coelho
The nl80211 channel switch count attribute (NL80211_ATTR_CH_SWITCH_COUNT) is specified as u32, but the specification uses u8 for the counter. To make sure strange things don't happen without informing the user, sanity check the value and return -EINVAL if it doesn't fit in u8.

Linville says: ==================== pull request: wireless-next 2014-09-22 Please pull this batch of updates intended for the 3.18 stream... For the mac80211 bits, Johannes says: "This time, I have some rate minstrel improvements, support for a very small feature from CCX that Steinar reverse-engineered, dynamic ACK timeout support, a number of changes for TDLS, early support for radio resource measurement and many fixes. Also, I'm changing a number of places to clear key memory when it's freed and Intel claims copyright for code they developed." For the bluetooth bits, Johan says: "Here are some more patches intended for 3.18. Most of them are cleanups or fixes for SMP. The only exception is a fix for BR/EDR L2CAP fixed channels which should now work better together with the L2CAP information request procedure." For the iwlwifi bits, Emmanuel says: "I fix here dvm which was broken by my last pull request. Arik continues to work on TDLS and Luca solved a few issues in CT-Kill. Eyal keeps digging into rate scaling code, more to come soon. Besides this, nothing really special here." Beyond that, there are the usual big batches of updates to ath9k, b43, mwifiex, and wil6210 as well as a handful of other bits here and there. Also, rtlwifi gets some btcoexist attention from Larry. Please let me know if there are problems! ==================== Had to adjust the wil6210 code to comply with Joe Perches's recent change in net-next to make the netdev_*() routines return void instead of 'int'.

Add nl80211 and driver API to validate, add and delete traffic streams with appropriate settings. The API calls for userspace doing the action frame handshake with the peer, and then allows only to set up the parameters in the driver. To avoid setting up a session only to tear it down again, the validate API is provided, but the real usage later can still fail so userspace must be prepared for that.

2014-09-03nl80211: clear skb cb before passing to netlinkJohannes Berg
In testmode and vendor command reply/event SKBs we use the skb cb data to store nl80211 parameters between allocation and sending. This causes the code for CONFIG_NETLINK_MMAP to get confused, because it takes ownership of the skb cb data when the SKB is handed off to netlink, and it doesn't explicitly clear it. Clear the skb cb explicitly when we're done and before it gets passed to netlink to avoid this issue.

2014-08-26cfg80211: clarify BSS probe response vs. beacon dataJohannes Berg
There are a few possible cases of where BSS data came from: 1) only a beacon has been received 2) only a probe response has been received 3) the driver didn't report what it received (this happens when using cfg80211_inform_bss[_width]()) 4) both probe response and beacon data has been received Unfortunately, in the userspace API, a few things weren't there: a) there was no way to differentiate cases 1) and 4) above without comparing the data of the IEs b) the TSF was always from the last frame, instead of being exposed for beacon/probe response separately like IEs Fix this by i) exporting a new flag attribute that indicates whether or not probe response data has been received - this addresses (a) ii) exporting a BEACON_TSF attribute that holds the beacon's TSF if a beacon has been received iii) not exporting the beacon attributes in case (3) above as that would just lead userspace into thinking the data actually came from a beacon when that isn't clear To implement this, track inside the IEs struct whether or not it (definitely) came from a beacon.

2014-08-26cfg80211: remove @gfp parameter from cfg80211_rx_mgmt()Vladimir Kondratiev
In the cfg80211_rx_mgmt(), parameter @gfp was used for the memory allocation. But, memory get allocated under spin_lock_bh(), this implies atomic context. So, one can't use GFP_KERNEL, only variants with no __GFP_WAIT. Actually, in all occurrences GFP_ATOMIC is used (wil6210 use GFP_KERNEL by mistake), and it should be this way or warning triggered in the memory allocation code. Remove @gfp parameter as no actual choice exist, and use hard coded GFP_ATOMIC for memory allocation.

2014-07-21wireless: fixup genregdb.awk for remove of antenna gain from wireless-regdLuis R. Rodriguez
Since "wireless-regdb: remove antenna gain" was merged in the wireless-regdb tree, the awk script parser has been incompatible with the 'official' regulatory database. This fixes that up. Without this change the max EIRP is set to 0 making 802.11 devices useless.

2014-05-22cfg80211: allow RSSI compensationEmmanuel Grumbach
Channels in 2.4GHz band overlap, this means that if we send a probe request on channel 1 and then move to channel 2, we will hear the probe response on channel 2. In this case, the RSSI will be lower than if we had heard it on the channel on which it was sent (1 in this case). The firmware / low level driver can parse the channel in the DS IE or HT IE and compensate the RSSI so that it will still have a valid value even if we heard the frame on an adjacent channel. This can be done up to a certain offset. Add this offset as a configuration for the low level driver. A low level driver that can compensate the low RSSI in this case should assign the maximal offset for which the RSSI value is still valid.
