2011-01-21cfg80211: Extend channel to frequency mapping for 802.11jBruno Randolf1-1/+2
Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping channel numbers in the 2GHz and 5GHz band we can't map from channel to frequency without knowing the band. This is no problem as in most contexts we know the band. In places where we don't know the band (and WEXT compatibility) we assume the 2GHz band for channels below 14. This patch does not implement all channel to frequency mappings defined in 802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz channels as well as 802.11y channels have been omitted. The following drivers have been updated to reflect the API changes: iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx. The drivers have been compile-tested only.

2010-12-16cfg80211: fix null pointer dereference with a custom regulatory requestLuis R. Rodriguez1-1/+3
Once we moved the core regulatory request to the queue and let the scheduler process it last_request will have been left NULL until the schedular decides to process the first request. When this happens and we are loading a driver with a custom regulatory request like all Atheros drivers we end up with a NULL pointer dereference. We fix this by checking if the request was a custom one.

2010-12-16nl80211: Add notification for dropped Deauth/DisassocJouni Malinen1-0/+26
Add a new notification to indicate that a received, unprotected Deauthentication or Disassociation frame was dropped due to management frame protection being in use. This notification is needed to allow user space (e.g., wpa_supplicant) to implement SA Query procedure to recover from association state mismatch between an AP and STA. This is needed to avoid getting stuck in non-working state when MFP (IEEE 802.11w) is used and a protected Deauthentication or Disassociation frame is dropped for any reason. After that, the station would silently discard any unprotected Deauthentication or Disassociation frame that could be indicating that the AP does not have association for the STA (when the Reason Code would be 6 or 7). IEEE Std 802.11w-2009, 11.13 describes this recovery mechanism. Signed-off-by: Jouni Malinen <j@w1.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-12-13cfg80211: Add antenna availability informationBruno Randolf1-0/+5
Add a field to wiphy for the hardware to report the availble antennas for configuration. Only if this is set to something bigger than zero, will the anntenna configuration ops be executed. Allthough this could be a simple number of antennas, I defined it as a bitmap of antennas which are available for configuration, since it's more consistent with the rest of the antenna API and there could be cases where the hardware allows only configuration of certain antennas. As it does not make much of a difference in size or normal usage, I think it's better to be able to support this, in case the need arises. The antenna configuration is now also checked against the availabe antennas and rejected if it does not match.

2010-12-07cfg80211/mac80211: add mesh join/leave commandsJohannes Berg1-9/+29
Instead of tying mesh activity to interface up, add join and leave commands for mesh. Since we must be backward compatible, let cfg80211 handle joining a mesh if a mesh ID was pre-configured when the device goes up. Note that this therefore must modify mac80211 as well since mac80211 needs to lose the logic to start the mesh on interface up. We now allow querying mesh parameters before the mesh is connected, which simply returns defaults. Setting them (internally renamed to "update") is only allowed while connected. Specify them with the new mesh join command instead where needed. In mac80211, beaconing must now also follow the mesh enabled/not enabled state, which is done by testing the mesh ID.

Enable this through the CMD_FRAME API, and allow it to wait for a response. A new command allows that wait to be aborted.

2010-11-17cfg80211: Add nl80211 antenna configurationBruno Randolf1-0/+3
Allow setting of TX and RX antennas configuration via nl80211. The antenna configuration is defined as a bitmap of allowed antennas to use. This API can be used to mask out antennas which are not attached or should not be used for other reasons like regulatory concerns or special setups. Separate bitmaps are used for RX and TX to allow configuring different antennas for receiving and transmitting. Each bitmap is 32 bit long, each bit representing one antenna, starting with antenna 1 at the first bit. If an antenna bit is set, this means the driver is allowed to use this antenna for RX or TX respectively; if the bit is not set the hardware is not allowed to use this antenna. Using bitmaps has the benefit of allowing for a flexible configuration interface which can support many different configurations and which can be used for 802.11n as well as non-802.11n devices. Instead of relying on some hardware specific assumptions, drivers can use this information to know which antennas are actually attached to the system and derive their capabilities based on that. 802.11n devices should enable or disable chains, based on which antennas are present (If all antennas belonging to a particular chain are disabled, the entire chain should be disabled). HT capabilities (like STBC, TX Beamforming, Antenna selection) should be calculated based on the available chains after applying the antenna masks. Should a 802.11n device have diversity antennas attached to one of their chains, diversity can be enabled or disabled based on the antenna information. Non-802.11n drivers can use the antenna masks to select RX and TX antennas and to enable or disable antenna diversity. While covering chainmasks for 802.11n and the standard "legacy" modes "fixed antenna 1", "fixed antenna 2" and "diversity" this API also allows more rare, but useful configurations as follows: 1) Send on antenna 1, receive on antenna 2 (or vice versa). This can be used to have a low gain antenna for TX in order to keep within the regulatory constraints and a high gain antenna for RX in order to receive weaker signals ("speak softly, but listen harder"). This can be useful for building long-shot outdoor links. Another usage of this setup is having a low-noise pre-amplifier on antenna 1 and a power amplifier on the other antenna. This way transmit noise is mostly kept out of the low noise receive channel. (This would be bitmaps: tx 1 rx 2). 2) Another similar setup is: Use RX diversity on both antennas, but always send on antenna 1. Again that would allow us to benefit from a higher gain RX antenna, while staying within the legal limits. (This would be: tx 0 rx 3). 3) And finally there can be special experimental setups in research and development even with pre 802.11n hardware where more than 2 antennas are available. It's good to keep the API simple, yet flexible. Signed-off-by: Bruno Randolf <br1@einfach.org> -- v7: Made bitmasks 32 bit wide and rebased to latest wireless-testing. Signed-off-by: John W.

2010-08-25cfg80211: add some documentationJohannes Berg1-6/+115
Add some documentation for cfg80211. I'm hoping some of the regulatory documentation will be filled by somebody more familiar with it, hint hint! :) Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-08-25cfg80211/mac80211: extensible frame processingJohannes Berg1-22/+34
Allow userspace to register for more than just action frames by giving the frame subtype, and make it possible to use this in various modes as well. With some tweaks and some added functionality this will, in the future, also be usable in AP mode and be able to replace the cooked monitor interface currently used in that case.

2010-08-25cfg80211: mark ieee80211_hdrlen constJohannes Berg1-1/+1
This function analyses only its single, value-passed argument, and has no side effects. Thus it can be const, which makes mac80211 smaller, for example: text data bss dec hex filename 362518 16720 884 380122 5ccda mac80211.ko (before) 362358 16720 884 379962 5cc3a mac80211.ko (after) a 160 byte saving in text size, and an optimisation because the function won't be called as often.

2010-06-24cfg80211/mac80211: Update set_tx_power to use mBm instead of dBm unitsJuuso Oikarinen1-14/+1
In preparation for a TX power setting interface in the nl80211, change the .set_tx_power function to use mBm units instead of dBm for greater accuracy and smaller power levels. Also, already in advance move the tx_power_setting enumeration to nl80211. This change affects the .tx_set_power function prototype. As a result, the corresponding changes are needed to modules using it. These are mac80211, iwmc3200wifi and rndis_wlan.
