cfg80211: add bitrate for 20MHz MCS 9

2016-11-15T13:34:00Z

Some drivers (ath10k) report MCS 9 @ 20MHz, which technically isn't defined. To get more meaningful value than 0 out of this however, just extrapolate a bitrate from ratio of MCS 7 and 9 in channels where it is allowed.

cfg80211: add ability to check DA/SA in A-MSDU decapsulation

2016-10-12T07:19:10Z

We should not accept arbitrary DA/SA inside A-MSDUs, it could be used to circumvent protections, like allowing a station to send frames and make them seem to come from somewhere else. Add the necessary infrastructure in cfg80211 to allow such checks, in further patches we'll start using them. Signed-off-by: Johannes Berg

cfg80211: let ieee80211_amsdu_to_8023s() take only header-less SKB

2016-10-12T07:19:10Z

There's only a single case where has_80211_header is passed as true, which is in mac80211. Given that there's only simple code that needs to be done before calling it, export that function from cfg80211 instead and let mac80211 call it itself. Signed-off-by: Johannes Berg

cfg80211: add add_nan_func / del_nan_func

2016-09-30T11:21:23Z

A NAN function can be either publish, subscribe or follow up. Make all the necessary verifications and just pass the request to the driver. Allow the user space application that starts NAN to forbid any other socket to add or remove functions.

cfg80211: add start / stop NAN commands

2016-09-30T11:21:14Z

This allows user space to start/stop NAN interface. A NAN interface is like P2P device in a few aspects: it doesn't have a netdev associated to it. Add the new interface type and prevent operations that can't be executed on NAN interface like scan. Define several attributes that may be configured by user space when starting NAN functionality (master preference and dual band operation) Signed-off-by: Andrei Otcheretianski Signed-off-by: Emmanuel Grumbach Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg

cfg80211: Add support for static WEP in the driver

2016-09-30T11:19:10Z

Add support for drivers that implement static WEP internally, i.e. expose connection keys to the driver in connect flow and don't upload the keys after the connection. Signed-off-by: David Spinadel Signed-off-by: Johannes Berg

cfg80211: reduce connect key caching struct size

2016-09-13T18:20:54Z

After the previous patches, connect keys can only (correctly) be used for storing static WEP keys. Therefore, remove all the data for dealing with key index 4/5 and reduce the size of the key material to the maximum for WEP keys. Signed-off-by: Johannes Berg

cfg80211: validate key index better

2016-09-13T18:20:53Z

Don't accept it if a key_idx < 0 snuck through, reject WEP keys with key index 4 and 5 (which are used for IGTKs) and don't allow IGTKs with key indices other than 4 and 5. This makes the key data match expectations better. Signed-off-by: Johannes Berg

cfg80211: identically validate beacon interval for AP/MESH/IBSS

2016-08-11T18:00:36Z

Beacon interval interface combinations validation was missing for MESH/IBSS join, add those. Johannes: also move the beacon interval check disallowing really tiny and really big intervals into the common function, which adds it for AP mode.

cfg80211: handle failed skb allocation
