2013-01-31bcma: add gpio_to_irqHauke Mehrtens1-2/+7
The old bcm47xx gpio code had support for gpio_to_irq, but the new code did not provide this function, but returned -ENXIO all the time. This patch adds the missing function. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-01-31ssb: add gpio_to_irqHauke Mehrtens1-0/+5
The old bcm47xx gpio code had support for gpio_to_irq, but the new code did not provide this function, but returned -ENXIO all the time. This patch adds the missing function. arch/mips/bcm47xx/wgt634u.c calls gpio_to_irq() and got the correct irq number with the old gpio handling code. With this patch the code in wgt634u.c should work again. I do not have a wgt634u to test this. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W.

2013-01-25cfg80211/nl80211: add API for MAC address ACLsVasanthakumar Thiagarajan2-2/+83
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. An initial ACL may be given to the NL80211_CMD_START_AP command and/or changed later with NL80211_CMD_SET_MAC_ACL. Black- and whitelists are supported, but not simultaneously.

2013-01-23Bluetooth: Add support for reading LE supported statesJohan Hedberg2-0/+7

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.

Depending on the driver, having ARP filtering for some addresses may be possible.

2013-01-18mac80211: add op to configure default key idYoni Divinsky1-0/+10
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. When hw_accel is enabled and encryption type is set to WEP, the driver should get the default key index from mac80211.

2013-01-18Bluetooth: Add a new workqueue for hci_request operationsJohan Hedberg1-0/+1
The hci_request function is blocking and cannot be called through the usual per-HCI device workqueue (hdev->workqueue). While hci_request is in progress any other work from the queue, including sending HCI commands to the controller would be blocked and eventually cause the hci_request call to time out. This patch adds a second workqueue to be used by operations needing hci_request and thereby avoiding issues with blocking other workqueue users.

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.
