2013-02-04cfg80211: expand per-station byte counters to 64bitVladimir Kondratiev2-4/+12
In per-station statistics, present 32bit counters are too small for practical purposes - with gigabit speeds, it get overlapped every few seconds. Expand counters in the struct station_info to be 64-bit. Driver can still fill only 32-bit and indicate in @filled only bits like STATION_INFO_[TR]X_BYTES; in case driver provides full 64-bit counter, it should also set in @filled bit STATION_INFO_[TR]RX_BYTES64 Netlink sends both 32-bit and 64-bit counters, if present, to not break userspace.

2013-02-04mac80211: always allow calling ieee80211_connection_loss()Johannes Berg1-0/+2
With multi-channel, there's a corner case where a driver doesn't receive a beacon soon enough to be able to sync its timers with the AP. In this case, the only recovery (after trying again) is to disconnect from the AP. Allow calling ieee80211_connection_loss() for such cases. To make that possible, modify the work function to not rely on the IEEE80211_HW_CONNECTION_MONITOR flag but use new state kept in the interface instead.

2013-01-31mac80211: start auth/assoc timeout on frame statusJohannes Berg1-1/+4
When sending authentication/association frames they might take a bit of time to go out because we may have to synchronise with the AP, in particular in the case where it's really a P2P GO. In this case the 200ms fixed timeout could potentially be too short if the beacon interval is relatively large. For drivers that report TX status we can do better. Instead of starting the timeout directly, start it only when the frame status arrives. Since then the frame was out on the air, we can wait shorter (the typical response time is supposed to be 30ms, wait 100ms.) Also, if the frame failed to be transmitted try again right away instead of waiting. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2013-01-31mac80211: inform the driver about update of dtim_periodEmmanuel Grumbach1-7/+9
Currently, when the driver requires the DTIM period, mac80211 will wait to hear a beacon before association. This behavior is suboptimal since some drivers may be able to deal with knowing the DTIM period after the association, if they get it at all. To address this, notify the drivers with bss_info_changed with the new BSS_CHANGED_DTIM_PERIOD flag when the DTIM becomes known. This might be when changing to associated, or later when the entire association was done with only probe response information. Rename the hardware flag for the current behaviour to IEEE80211_HW_NEED_DTIM_BEFORE_ASSOC to more accurately reflect its behaviour. IEEE80211_HW_NEED_DTIM_PERIOD is no longer accurate as all drivers get the DTIM period now, just not before association.

Add API to enable drivers to implement MAC address based access control in AP/P2P GO mode. Capable drivers advertise this capability by setting the maximum number of MAC addresses in such a list in wiphy->max_acl_mac_addrs.

2013-01-19mac80211: allow drivers to access IPv6 informationJohannes Berg1-0/+9
To be able to implement NS response offloading (in regular operation or while in WoWLAN) drivers need to know the IPv6 addresses assigned to interfaces. Implement an IPv6 notifier in mac80211 to call the driver when addresses change. Unlike for IPv4, implement it as a callback rather than as a list in the BSS configuration, that is more flexible.

There are hardwares which support offload of data packets for example when auto ARP is enabled the hw will send the ARP response. In such cases if WEP encryption is configured the hw must know the default WEP key in order to encrypt the packets correctly.

2013-01-17nl80211: allow user-space to set address for P2P_DEVICEArend van Spriel1-0/+4
As per email discussion Jouni Malinen pointed out that: "P2P message exchanges can be executed on the current operating channel of any operation (both P2P and non-P2P station). These can be on 5 GHz and even on 60 GHz (so yes, you _can_ do GO Negotiation on 60 GHz). As an example, it would be possible to receive a GO Negotiation Request frame on a 5 GHz only radio and then to complete GO Negotiation on that band. This can happen both when connected to a P2P group (through client discoverability mechanism) and when connected to a legacy AP (assuming the station receive Probe Request frame from full scan in the beginning of P2P device discovery)." This means that P2P messages can be sent over different radio devices. However, these should use the same P2P device address so it should be able to provision this from user-space. This patch adds a parameter for this to struct vif_params which should only be used during creation of the P2P device interface.

2013-01-17{cfg,nl}80211: mesh power mode primitives and userspace accessMarco Porsch2-0/+68
Add the nl80211_mesh_power_mode enumeration which holds possible values for the mesh power mode. These modes are unknown, active, light sleep and deep sleep. Add power_mode entry to the mesh config structure to hold the user-configured default mesh power mode. This value will be used for new peer links. Add the dot11MeshAwakeWindowDuration value to the mesh config. The awake window is a duration in TU describing how long the STA will stay awake after transmitting its beacon in PS mode. Add access routines to: - get/set local link-specific power mode (STA) - get remote STA's link-specific power mode (STA) - get remote STA's non-peer power mode (STA) - get/set default mesh power mode (mesh config) - get/set mesh awake window duration (mesh config) All config changes may be done at mesh runtime and take effect immediately.

2013-01-03mac80211: split TX aggregation stop actionJohannes Berg1-5/+17
When TX aggregation is stopped, there are a few different cases: - connection with the peer was dropped - session stop was requested locally - session stop was requested by the peer - connection was dropped while a session is stopping The behaviour in these cases should be different, if the connection is dropped then the driver should drop all frames, otherwise the frames may continue to be transmitted, aggregated in the case of a locally requested session stop or unaggregated in the case of the peer requesting session stop. Split these different cases so that the driver can act accordingly; however, treat local and remote stop the same way and ask the driver to not send frames as aggregated packets any more. In the case of connection drop, the stop callback the driver is otherwise supposed to call is no longer required. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2013-01-03nl80211/mac80211: support full station state in AP modeJohannes Berg1-0/+16
Today, stations are added already associated. That is inefficient if, for example, the driver has no room for stations any more because then the station will go through the entire auth/assoc handshake, only to be kicked out afterwards. To address this a bit better, at least with drivers using the new station state callback, allow hostapd to add stations in unauthenticated mode, just after receiving the AUTH frame, before even replying. Thus if there's no more space at that point, it can send a negative auth frame back. It still needs to handle later state transition errors though, of course.
