mac80211: don't drop mesh peering frames from unknown STA

2012-12-06T12:58:43Z

Previously, mesh peering frames from a STA without a station entry were being dropped. Mesh Peering Open and other frames (WLAN_CATEGORY_SELF_PROTECTED) are valid mesh peering frames even if received from a yet unknown station; the STA entry will be created in mesh_peer_init later. The problem didn't occur previously since both STAs receive each other's beacons which created the STA entry. However, this causes an unnecessary delay and beacons might not be received if either node is in PS mode. Signed-off-by: Marco Porsch [reword commit log a bit] Signed-off-by: Johannes Berg

mac80211: skip radiotap space calculation if no monitor exists

2012-12-05T15:54:59Z

The radiotap header length "needed_headroom" is only required if we're sending the skb to a monitor interface. Hence, move the calculation a bit later so the calculation can be skipped if no monitor interface is present. Signed-off-by: Helmut Schaa Signed-off-by: Johannes Berg

mac80211: fix potential NULL dereference

2012-11-28T12:46:22Z

Smatch complains that we could dereference skb later in the function. It's probably unlikely, but we may as well return here and avoid it. Signed-off-by: Dan Carpenter [change summary] Signed-off-by: Johannes Berg

mac80211: support (partial) VHT radiotap information

2012-11-27T10:56:18Z

Add some information that we have about VHT to radiotap. This at least lets one see the MCS and NSS information. Signed-off-by: Johannes Berg

mac80211: support drivers reporting VHT RX

2012-11-26T11:42:59Z

Add support to mac80211 for having drivers report received VHT MCS information. Signed-off-by: Johannes Berg

mac80211: in ADHOC don't update last_rx if sta is not authorized

2012-11-26T10:31:39Z

It does not make sense to keep a station alive if it is not authorised at all. If IBSS/RSN is used it could also be the case that something went wrong during the keys exchange and the stations ended up in a not recoverable state. By not updating last_rx we are giving the station a chance to be deleted and to start the key exchange once again from scratch. Signed-off-by: Antonio Quartulli Signed-off-by: Johannes Berg

mac80211: fix radiotap vendor area skipping

2012-11-23T07:41:25Z

The radiotap vendor area in the skb head must be skipped and accounted for in a few functions until it is removed. I missed this in my patch, so a few places use this data as though it was the 802.11 header, fix these places. Reported-by: Wojciech Dubowik Tested-by: Wojciech Dubowik Signed-off-by: Johannes Berg

mac80211: support radiotap vendor namespace RX data

2012-11-19T14:45:46Z

In some cases, in particular for experimentation, it can be useful to be able to add vendor namespace data to received frames in addition to the normal radiotap data. Allow doing this through mac80211 by adding fields to the RX status descriptor that describe the data while the data itself is prepended to the frame. Also add some example code to hwsim, but don't enable it because it doesn't use a proper OUI identifier. Signed-off-by: Johannes Berg

mac80211: introduce IEEE80211_NUM_TIDS and use it

2012-11-19T14:44:00Z

Introduce IEEE80211_NUM_TIDS in the generic 802.11 header file and use it in place of STA_TID_NUM and NUM_RX_DATA_QUEUES which are both really the number of TIDs. Signed-off-by: Johannes Berg

mac80211: support RX_FLAG_MACTIME_END

2012-11-13T20:43:55Z

Allow drivers to indicate their mactime is at RX completion and adjust for this in mac80211. Also rename the existing RX_FLAG_MACTIME_MPDU to RX_FLAG_MACTIME_START to clarify its intent.
