2015-01-27mac80111: Add BIP-CMAC-256 cipherJouni Malinen1-0/+9
This allows mac80211 to configure BIP-CMAC-256 to the driver and also use software-implementation within mac80211 when the driver does not support this with hardware accelaration. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

This makes cfg80211 aware of the GCMP, GCMP-256, CCMP-256, BIP-GMAC-128, BIP-GMAC-256, and BIP-CMAC-256 cipher suites. These new cipher suites were defined in IEEE Std 802.11ac-2013. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2014-10-09mac80211: add extended channel switching capability if the driver supports CSALuciano Coelho1-0/+5
The Extended Channel Switching capability bit in the extended capabilities element must be set if the driver supports CSA on non-beaconing interfaces. Since this capability needs to be set during driver registration, the extended_capabiliities global variable needs to be moved to the local structure so that it can be modified.

2014-09-11cfg80211: add WMM traffic stream APIJohannes Berg1-0/+4
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.

2014-09-08mac80211: support DTPC IE (from Cisco Client eXtensions)Steinar H. Gunderson1-1/+2
Linux already supports 802.11h, where the access point can tell the client to reduce its transmission power. However, 802.11h is only defined for 5 GHz, where the need for this is much smaller than on 2.4 GHz. Cisco has their own solution, called DTPC (Dynamic Transmit Power Control). Cisco APs on a controller sometimes but not always send 802.11h; they always send DTPC, even on 2.4 GHz. This patch adds support for parsing and honoring the DTPC IE in addition to the 802.11h element (they do not always contain the same limits, so both must be honored); the format is not documented, but very simple. Tested (on top of wireless.git and on 3.16.1) against a Cisco Aironet 1142 joined to a Cisco 2504 WLC, by setting various transmit power levels for the given access points and observing the results. The Wireshark 802.11 dissector agrees with the interpretation of the element, except for negative numbers, which seem to never happen anyway. Signed-off-by: Steinar H.

2014-02-05mac80211: fix bufferable MMPDU RX handlingJohannes Berg1-0/+14
Action, disassoc and deauth frames are bufferable, and as such don't have the PM bit in the frame control field reserved which means we need to react to the bit when receiving in such a frame. Fix this by introducing a new helper ieee80211_is_bufferable_mmpdu() and using it for the RX path that currently ignores the PM bit in any non-data frames for doze->wake transitions, but listens to it in all frames for wake->doze transitions, both of which are wrong. Also use the new helper in the TX path to clean up the code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Add support for the secondary channel offset IE in channel switch announcements. This is necessary for proper handling of CSA on HT access points. For this to work it is also necessary to convert everything here to use chandef structs instead of just channels. The driver updates aren't really correct though. In particular, the TI wl18xx driver update can't possibly be right since it just ignores the new channel width for lack of firmware API. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Implement restricting peer VHT capabilities to the device's own capabilities. This is useful when a single driver supports more than one device and the devices have different capabilities (often they will differ in the number of spatial streams), but in particular is also necessary for VHT capability overrides to work correctly -- otherwise it'd be possible to e.g. advertise, due to overrides, that TX-STBC is not supported, but then still use it to TX to the AP because it supports RX-STBC.

Regardless of what header features they use, or if they align the IP header or not, 802.11 packets from all drivers guarantee a 2-byte alignment (and there's a debug WARN_ON in case they don't). Annotate packet structs with __aligned(2) to allow the compiler to use 16-bit load/store operations on platforms with extremely inefficient unaligned access (e.g. MIPS).

2013-02-04mac80211: mesh power save basicsMarco Porsch1-0/+8
Add routines to - maintain a PS mode for each peer and a non-peer PS mode - indicate own PS mode in transmitted frames - track neighbor STAs power modes - buffer frames when neighbors are in PS mode - add TIM and Awake Window IE to beacons - release frames in Mesh Peer Service Periods Add local_pm to sta_info to represent the link-specific power mode at this station towards the remote station. When a peer link is established, use the default power mode stored in mesh config. Update the PS status if the peering status of a neighbor changes. Maintain a mesh power mode for non-peer mesh STAs. Set the non-peer power mode to active mode during peering. Authenticated mesh peering is currently not working when either node is configured to be in power save mode. Indicate the current power mode in transmitted frames. Use QoS Nulls to indicate mesh power mode transitions. For performance reasons, calls to the function setting the frame flags are placed in HWMP routing routines, as there the STA pointer is already available. Add peer_pm to sta_info to represent the peer's link-specific power mode towards the local station. Add nonpeer_pm to represent the peer's power mode towards all non-peer stations. Track power modes based on received frames. Add the ps_data structure to ieee80211_if_mesh (for TIM map, PS neighbor counter and group-addressed frame buffer). Set WLAN_STA_PS flag for STA in PS mode to use the unicast frame buffering routines in the tx path. Update num_sta_ps to buffer and release group-addressed frames after DTIM beacons. Announce the awake window duration in beacons if in light or deep sleep mode towards any peer or non-peer. Create a TIM IE similarly to AP mode and add it to mesh beacons. Parse received Awake Window IEs and check TIM IEs for buffered frames. Release frames towards peers in mesh Peer Service Periods. Use the corresponding trigger frames and monitor the MPSP status. Append a QoS Null as trigger frame if neccessary to properly end the MPSP. Currently, in HT channels MPSPs behave imperfectly and show large delay spikes and frame losses.
