2013-10-19net: misc: Remove extern from function prototypesJoe Perches
There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

2013-10-14wireless: radiotap: fix parsing buffer overrunJohannes Berg
When parsing an invalid radiotap header, the parser can overrun the buffer that is passed in because it doesn't correctly check 1) the minimum radiotap header size 2) the space for extended bitmaps The first issue doesn't affect any in-kernel user as they all check the minimum size before calling the radiotap function. The second issue could potentially affect the kernel if an skb is passed in that consists only of the radiotap header with a lot of extended bitmaps that extend past the SKB. In that case a read-only buffer overrun by at most 4 bytes is possible. Fix this by adding the appropriate checks to the parser.

2013-10-01regulatory: enable channels 52-64 and 100-144 for world roamingJohannes Berg
If allowed in a country, these channels typically require DFS so mark them as such. Channel 144 is a bit special, it's coming into use now to allow more VHT 80 channels, but world roaming with passive scanning is acceptable anyway. It seems fairly unlikely that it'll be used as the control channel for a VHT AP, but it needs to be present to allow a full VHT connection to an AP that uses it as one of the secondary channels. Also enable VHT 160 on these channels, and also for channels 36-48 to be able to use VHT 160 there. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-08-14cfg80211: don't request disconnect if not connectedJohannes Berg
Neil Brown reports that with libertas, my recent cfg80211 SME changes in commit ceca7b7121795ef81bd598a240d53a92566 ("cfg80211: separate internal SME implementation") broke libertas suspend because it we now asked it to disconnect while already disconnected. The problematic change is in cfg80211_disconnect() as it previously checked the SME state and now calls the driver disconnect operation unconditionally.

2013-07-16cfg80211/nl80211: Add packet coalesce supportAmitkumar Karwar
In most cases, host that receives IPv4 and IPv6 multicast/broadcast packets does not do anything with these packets. Therefore the reception of these unwanted packets causes unnecessary processing and power consumption. Packet coalesce feature helps to reduce number of received interrupts to host by buffering these packets in firmware/hardware for some predefined time. Received interrupt will be generated when one of the following events occur. a) Expiration of hardware timer whose expiration time is set to maximum coalescing delay of matching coalesce rule. b) Coalescing buffer in hardware reaches it's limit. c) Packet doesn't match any of the configured coalesce rules. This patch adds set/get configuration support for packet coalesce. User needs to configure following parameters for creating a coalesce rule. a) Maximum coalescing delay b) List of packet patterns which needs to be matched c) Condition for coalescence. pattern 'match' or 'no match' Multiple such rules can be created. This feature needs to be advertised during driver initialization. Drivers are supposed to do required firmware/hardware settings based on user configuration.
