2014-12-31Revert "cfg80211: make WEXT compatibility unselectable"Jiri Kosina1-1/+1
This reverts commit 24a0aa212ee2dbe44360288684478d76a8e20a0a. It's causing severe userspace breakage. Namely, all the utilities from wireless-utils which are relying on CONFIG_WEXT (which means tools like 'iwconfig', 'iwlist', etc) are not working anymore. There is a 'iw' utility in newer wireless-tools, which is supposed to be a replacement for all the "deprecated" binaries, but it's far away from being massively adopted. Please see [1] for example of the userspace breakage this is causing. In addition to that, Larry Finger reports [2] that this patch is also causing ipw2200 driver being impossible to build. To me this clearly shows that CONFIG_WEXT is far, far away from being "deprecated enough" to be removed.

2014-12-12nl80211: check matches array length before acessing itLuciano Coelho1-1/+1
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).

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.

In kernel we have %*pE specifier to print an escaped buffer. All users now switched to that approach. This fixes a bug as well. The current implementation wrongly prints octal numbers: only two first digits are used in case when 3 are required and the rest of the string ends up cut off. Additionally by default the \f, \v, \a, and \e are escaped to their alphabetic representation. It's safe to do since it is currently used for messaging only.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== pull request: wireless-next 2014-09-22 Please pull this batch of updates intended for the 3.18 stream... For the mac80211 bits, Johannes 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." For the bluetooth bits, Johan says: "Here are some more patches intended for 3.18. Most of them are cleanups or fixes for SMP. The only exception is a fix for BR/EDR L2CAP fixed channels which should now work better together with the L2CAP information request procedure." For the iwlwifi bits, Emmanuel says: "I fix here dvm which was broken by my last pull request. Arik continues to work on TDLS and Luca solved a few issues in CT-Kill. Eyal keeps digging into rate scaling code, more to come soon. Besides this, nothing really special here." Beyond that, there are the usual big batches of updates to ath9k, b43, mwifiex, and wil6210 as well as a handful of other bits here and there. Also, rtlwifi gets some btcoexist attention from Larry. Please let me know if there are problems! ==================== Had to adjust the wil6210 code to comply with Joe Perches's recent change in net-next to make the netdev_*() routines return void instead of 'int'.

2014-09-11cfg80211: allow requesting SMPS mode on ap startEliad Peller1-0/+24
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 Peller3-10/+25
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 Berg3-0/+185
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 Berg1-4/+21
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 Berg1-7/+3
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>
