2011-11-09rndis_wlan: release BSS structures returned by cfg80211_inform_bss()Jussi Kivilinna
Patch fixes rndis_wlan to release referenced BSS structure returned by cfg80211_inform_bss(). Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-11-09cfg80211: annotate cfg80211_inform_bssJohannes Berg
This function returns a referenced BSS struct (or NULL), annotate with __must_check. It seems that a lot of drivers get this completely wrong and leak all BSS structs as a result.

2011-11-09mac80211: handle HT PHY BSS membership selector value correctlyChristian Lamparter
802.11n-2009 extends the supported rates element with a magic value which can be used to prevent legacy stations from joining the BSS. However, this magic value is not a rate like the others and the magic can simply be ignored/skipped at this late stage.

2011-11-09Bluetooth: Move pending management command list into struct hci_devJohan Hedberg
This patch moves the pending management command list (previously global to mgmt.c) into struct hci_dev. This makes it possible to do proper locking when accessing it (through the existing hci_dev locks) and thereby avoid race conditions.

2011-11-09Bluetooth: Pass full hci_dev struct to mgmt callbacksJohan Hedberg
The current global pending command list in mgmt.c is racy. Possibly the simplest way to fix it is to have per-hci dev lists instead of a global one (all commands that need a pending struct are hci_dev specific). This way the list can be protected using the already existing per-hci dev lock. To enable this refactoring the first thing that needs to be done is to ensure that the mgmt functions have access to the hci_dev struct (instead of just the dev id).
