* Merge branch 'for-john' of ↵John W. Linville2014-01-1339-866/+1047

| * mac80211_hwsim: restore regulatory testing functionalityJohannes Berg2014-01-102-3/+222
| | | | | | | | | | | | | | | | Restore the original regulatory testing functionality and also make it more flexible by allowing the parameters to be specified when creating a dynamic radio. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: allow creating/destroying radios on the flyJohannes Berg2014-01-102-6/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new commands to the hwsim generic netlink family to allow creating and destroying radios on the fly. The number of channels a radio supports can be specified when it's created, if it isn't the module parameter will be used as default. This should be extended in the future to allow other parameters to be specified, e.g. * list of channels * interface combinations, particularly P2P_DEVICE support * regtest * and pretty much all other hardware capabilities Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: register netlink even with multi-channelJohannes Berg2014-01-101-8/+16
| | | | | | | | | | | | | | | | | | Reject wmediumd registrations when any devices have multi-channel capability, but register the generic netlink family unconditionally to make it possible to add new commands that shouldn't depend on the number of (default) channels. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: verify wmediumd socketJohannes Berg2014-01-101-0/+9
| | | | | | | | | | | | | | | | There can't be two wmediumd instances controlling hwsim, so reject registration from a second one and verify in the commands that it's the correct instance calling. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: shuffle code to prepare for dynamic radiosJohannes Berg2014-01-101-413/+413
| | | | | | | | | | | | | | This will make the next patch, adding support for netlink, smaller and more readable. The code is not modified here. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: minor netlink cleanupsJohannes Berg2014-01-101-41/+23
| | | | | | | | | | | | | | Use u8 pointer instead of the struct mac_address and do some other small cleanups. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: assign index from separate counterJohannes Berg2014-01-101-2/+8
| | | | | | | | | | | | | | To later allow dynamic registration, assign the index for the struct device and MAC address from a new free-running counter. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: minimize rctbl module parameter usageJohannes Berg2014-01-101-3/+3
| | | | | | | | | | | | | | Check the flag that the module parameter sets instead, so later radios can use different parameters. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: refactor radio cleanupJohannes Berg2014-01-101-14/+18
| | | | | | | | | | | | | | Refactor the radio cleanup into a new function to later allow deleting a single radio from the list. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: refactor radio registrationJohannes Berg2014-01-101-230/+225
| | | | | | | | | | | | | | | | | | In order to support dynamic radio registration in the future, refactor the actual registration into a new function with only minor cleanups. Since it had to change anyway, also clean up the init error paths. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: remove regtest for nowJohannes Berg2014-01-101-220/+0
| | | | | | | | | | | | | | | | The regtest thing worked based on the radio loop, but with more dynamic radio registration that loop won't really exist as is. We can add it back later with proper dynamic code. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: prepare for different channel supportJohannes Berg2014-01-101-31/+36
| | | | | | | | | | | | | | | | | | Prepare the code to support, in theory, different devices with a different number of channels supported. Right now this doesn't really change anything, but will allow for dynamic device registration in the future. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211_hwsim: clean up netlink exit codeJohannes Berg2014-01-101-7/+1
| | | | | | | | | | | | | | There's no need to print a message, and genl_unregister_family() can't really fail so remove the error message there as well. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| * mac80211: handle MMPDUs at EOSP correctlyJohannes Berg2014-01-102-13/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | If a uAPSD service period ends with an MMPDU, we currently just send that MMPDU, but it obviously won't get the EOSP bit set as it doesn't have a QoS header. This contradicts the standard, so add a QoS-nulldata frame after the MMPDU to properly terminate the service period with a frame that has EOSP set. Also fix a bug wrt. the TID for the MMPDU, it shouldn't be set to 0 unconditionally but use the actual TID that was assigned. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
| * mac80211: reset TX info flags when frame will be reprocessedJohannes Berg2014-01-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | The temporary TX info flags need to be cleared if the frame will be processed through the TX handlers again, otherwise it can get messed up. This fixes a bug that happened when an aggregation session was stopped while the station was sleeping - some frames might get transmitted marked as aggregation erroneously without this fix.

| * mac80211: release multiple ACs in uAPSD, fix more-data bugJohannes Berg2014-01-101-42/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a response for PS-Poll or a uAPSD trigger frame is sent, the more-data bit should be set according to 802.11-2012 11.2.1.5 h), meaning that it should indicate more data on the relevant ACs (delivery-enabled or nondelivery-enabled for uAPSD or PS-Poll.) In, for example, the following scenario: * 1 frame on VO queue (either in driver or in mac80211) * at least 1 frame on VI queue (in the driver) * both VO/VI are delivery-enabled * uAPSD trigger frame received The more-data flag to the driver would not be set, even though it should be. While fixing this, I noticed that we should really release frames from multiple ACs where there's data buffered in the driver for the corresponding TIDs. To address all this, restructure the code a bit to consider all ACs if we only release driver frames or only buffered frames. This also addresses the more-data bug described above as now the TIDs will all be marked as released, so the driver will have to check the number of frames. While at it, clarify some code and comments and remove the found variable, replacing it with the appropriate sw/hw release check.

| * mac80211: fix PS-Poll driver release TIDJohannes Berg2014-01-101-1/+13
| | | | | | | | | | | | | | | | | | | | Using ffs() for the PS-Poll release TID is wrong, it will cause frames to be released in order 0 1 2 3 4 5 6 7 instead of the correct 7 6 5 4 3 0 2 1. Fix this by adding a new function that implements "highest priority TID" properly. Reported-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While getting the retry limit, wext-compat returns the value without updating the flag for retry->flags is 0. Also in this case, it updates long retry flag when short and long retry value are unequal. So, iwconfig never showing "Retry short limit" and showing "Retry long limit" when both values are unequal.
