2014-12-12nl80211: check matches array length before acessing itLuciano Coelho
If the userspace passes a malformed sched scan request (or a net detect wowlan configuration) by adding a NL80211_ATTR_SCHED_SCAN_MATCH attribute without any nested matchsets, a NULL pointer dereference will occur. Fix this by checking that we do have matchsets in our array before trying to access it.

When the regulatory settings change, some channels might become invalid. Disconnect interfaces acting on these channels, after giving userspace code a grace period to leave them. This mode is currently opt-in, and not all interface operating modes are supported for regulatory-enforcement checks. A wiphy that wishes to use the new enforcement code must specify an appropriate regulatory flag, and all its supported interface modes must be supported by the checking code.

For multi-vif channel switches, we want to send NL80211_CMD_CH_SWITCH_NOTIFY to the userspace to let it decide whether other interfaces need to be moved as well.

This allows userspace to take action, for instance, by requesting other interfaces to switch channel as necessary. This patch introduces a function that allows the drivers to send this notification. It should be used when the driver starts processing a channel switch initiated by a remote device (eg. when a STA receives a CSA from the AP) and when it successfully starts a userspace-triggered channel switch (eg. when hostapd triggers a channel swith in the AP).

A mandatory parameters during the ocb_join operation are 'center frequency' and 'channel width (5/10 MHz)'.

During the review of the corresponding wpa_supplicant patches we noticed that the only way for it to detect that this functionality is supported currently is to check for the command support. This can be misleading though, as the command was also designed to, in the future, support pure 802.11 TSPECs. Expose the WMM-TSPEC feature flag to nl80211 so later we can also expose an 802.11-TSPEC feature flag (if needed) to differentiate the two cases.

git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next Johannes Berg <johannes@sipsolutions.net> says: "This time, I have some rate minstrel improvements, support for a very small feature from CCX that Steinar reverse-engineered, dynamic ACK timeout support, a number of changes for TDLS, early support for radio resource measurement and many fixes. Also, I'm changing a number of places to clear key memory when it's freed and Intel claims copyright for code they developed." Conflicts: net/mac80211/iface.c Signed-off-by: John W.

2014-09-11cfg80211: allow requesting SMPS mode on ap startEliad Peller
Add feature bits to indicate device support for static-smps and dynamic-smps modes. Add a new NL80211_ATTR_SMPS_MODE attribue to allow configuring the smps mode to be used by the ap (e.g. configuring to ap to dynamic smps mode will reduce power consumption while having minor effect on throughput) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-09-11cfg80211/mac80211: add wmm info to assoc eventEliad Peller
Userspace might need to know what queues are configured for uapsd (e.g. for setting proper default values in tspecs). Add this bitmap to the association event (inside wmm nested attribute) Add additional parameter to cfg80211_rx_assoc_resp, and update its callers.

2014-09-11cfg80211: add WMM traffic stream APIJohannes Berg
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.

2014-09-11cfg80211: clear nl80211 messages carrying keys after processingJohannes Berg
Clear any nl80211 messages that might contain keys after processing them to avoid leaving their data in memory "forever" after they've been freed. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-09-11cfg80211: don't put kek/kck/replay counter on the stackJohannes Berg
There's no need to put the values on the stack, just pass a pointer to the data in the nl80211 message. This reduces stack usage and avoids potential issues with putting sensitive data on the stack. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2014-09-11cfg80211: clear wext keys when freeing and removing themJohannes Berg
When freeing the keys stored for wireless extensions, clear the memory to avoid having the key material stick around in memory "forever". Similarly, when userspace overwrites a key, actually clear it instead of just setting the key length to zero. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
