2015-12-04mac80211: add atomic uploaded keys iteratorEliad Peller4-4/+79
add ieee80211_iter_keys_rcu() to iterate over uploaded keys in atomic context (when rcu is locked) The station removal code removes the keys only after calling synchronize_net(), so it's not safe to iterate the keys at this point (and postponing the actual key deletion with call_rcu() might result in some badly-ordered ops calls). Add a flag to indicate a station is being removed, and skip the configured keys if it's set.

2015-12-04mac80211: allow the driver to send EOSP when neededEmmanuel Grumbach3-43/+148
This can happen when the driver needs to send less frames than expected and then needs to close the SP. Mac80211 still needs to set the more_data properly based on its buffer state (ps_tx_buffer and buffered frames on other TIDs). To that end, refactor the code that delivers frames upon uAPSD trigger frames to be able to get only the more_data bit without actually delivering those frames in case the driver is just asking to set a NDP with EOSP and MORE_DATA bit properly set.

2015-12-04nl80211: clarify NL80211_ATTR_SCHED_SCAN_DELAY usage with net-detectLuca Coelho1-2/+3
In this attribute's documentation, it was not clear whether the delay started counting when WoWLAN net-detect was enabled or when the system was suspended. The correct answer is that it starts when the system suspends (which is when, in practice, the scan is scheduled). Clarify that in the nl80211.h documentation.

2015-12-04mac80211: remove string from unaligned packet warningJohannes Berg1-2/+1
This really should never happen except very early in the process of bringing up a new driver, at which point you'll have to add more debugging in the driver and this string isn't useful.

2015-12-04lib80211: ratelimit key index mismatchJohannes Berg2-4/+4
This indicates a driver key selection issue, but even then there's no point in printing it all the time, so ratelimit it. Also remove the priv pointer from it -- people debugging will only have a single device anyway and it's useless as anything but a cookie. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2015-12-02mac80211: fix off-channel mgmt-tx uninitialized variable usageJohannes Berg1-2/+6
In the last change here, I neglected to update the cookie in one code path: when a mgmt-tx has no real cookie sent to userspace as it doesn't wait for a response, but is off-channel. The original code used the SKB pointer as the cookie and always assigned the cookie to the TX SKB in ieee80211_start_roc_work(), but my change turned this around and made the code rely on a valid cookie being passed in. Unfortunately, the off-channel no-wait TX path wasn't assigning one at all, resulting in an uninitialized stack value being used. This wasn't handed back to userspace as a cookie (since in the no-wait case there isn't a cookie), but it was tested for non-zero to distinguish between mgmt-tx and off-channel. Fix this by assigning a dummy non-zero cookie unconditionally, and get rid of a misleading comment and some dead code while at it. I'll clean up the ACK SKB handling separately later.

DFS channels should not be actively scanned as we can't be sure if we are allowed or not.

2015-11-24vrf: remove slave queue and private slave structNikolay Aleksandrov1-63/+5
The private slave queue and slave struct haven't been used for anything and aren't needed, this allows to reduce memory usage and simplify enslave/release. We can use netdev_for_each_lower_dev() to free the vrf ports when deleting a vrf device.
