mac80211: fix memory leak in device registration error path

2012-11-09T08:48:43Z

If the cipher suites need to be allocated, but this allocation fails, this leaks the internal scan request. Fix that by going to the correct error handling label. Signed-off-by: Johannes Berg

mac80211: change locking around ieee80211_recalc_smps

2012-09-14T12:09:25Z

Make the function acquire the necessary mutex itself to simplify the callers. Signed-off-by: Johannes Berg

mac80211: handle power constraint/country IE better

2012-09-14T12:06:51Z

Currently, mac80211 uses the power constraint IE, and reduces the regulatory max TX power by it. This can cause issues if the AP is advertising a large power constraint value matching a high TX power in its country IE, for example in this case: ... Country: US Environment: Indoor/Outdoor ... Channels [157 - 157] @ 30 dBm ... Power constraint: 13 dB ... What happened here is that our local regulatory TX power is 15 dBm, and gets reduced by 13 dB so we end up with only 2 dBm effective TX power, which is way too low. Instead, handle the country IE/power constraint IE combined and restrict our TX power to the max of the regulatory power and the maximum power advertised by the AP, in this case 17 dBm (= 30 dBm - 13 dB). Also print a message when this happens to let the user know and help us debug issues with it. Reported-by: Carl A. Cook Tested-by: Carl A. Cook Signed-off-by: Johannes Berg

mac80211: convert ops checks to WARN_ON

2012-08-20T12:13:44Z

There's no need to BUG_ON when a driver registers invalid operations, warn and return an error. Signed-off-by: Johannes Berg

mac80211: support P2P Device abstraction

2012-08-20T11:58:22Z

After cfg80211 got a P2P Device abstraction, add support to mac80211. Whether it really is supported or not will depend on whether or not the driver has support for it, but mac80211 needs to change to be able to support drivers that need a P2P Device. Signed-off-by: Johannes Berg

mac80211: track scheduled scan virtual interface

2012-07-12T10:10:43Z

Instead of tracking whether or not we're in a scheduled scan, track the virtual interface (sdata) in an RCU-protected pointer to make it usable from RX to check the MAC address. Signed-off-by: Johannes Berg

mac80211: remove tx_frags driver callback

2012-07-02T13:40:18Z

The implementation of tx_frags is buggy due to not handling queue stop, and there's no driver implementing it so remove it. Signed-off-by: Johannes Berg

mac80211: include VHT capability IE in probe requests

Insert the VHT capability IE into probe requests. Signed-off-by: Mahesh Palivela Signed-off-by: Johannes Berg

cfg80211: don't allow WoWLAN support without CONFIG_PM

2012-06-27T15:55:11Z

When CONFIG_PM is disabled, no device can possibly support WoWLAN since it can't go to sleep to start with. Due to this, mac80211 had even rejected the hardware registration. By making all the code and data for WoWLAN depend on CONFIG_PM we can promote this runtime error to a compile-time error. Add #ifdef around all WoWLAN code to remove it in systems that don't need it as they never suspend. Cc: Kalle Valo Acked-by: Luciano Coelho Signed-off-by: Johannes Berg

mac80211: Allow userspace to register for auth frames in IBSS

2012-06-20T18:03:43Z

Set the necessary flags to allow user space applications to register for authentication frames on IBSS interfaces. This is useful for situations where userspace applications want to control key negotiation between stations. Signed-off-by: Will Hawkins [reword commit message a bit] Signed-off-by: Johannes Berg
