* mac80211: add interface list lockJohannes Berg2009-01-29
| | | | | | | | | | | | | | Using only the RTNL has a number of problems, most notably that ieee80211_iterate_active_interfaces() and other interface list traversals cannot be done from the internal workqueue because it needs to be flushed under the RTNL. This patch introduces a new mutex that protects the interface list against modifications. A more detailed explanation is part of the code change.

* mac80211: flush workqueue a second time in suspend()Bob Copeland2009-01-29
| | | | | | | | | Drivers can theoretically queue more work in one of their callbacks from mac80211 suspend, so let's flush it once more to be on the safe side, just before calling ->stop(). Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: change workqueue back to non-freezeableBob Copeland2009-01-29
| | | | | | | | | | | | | | | | | | | | | "mac80211: make workqueue freezable" made the mac80211 workqueue freezeable to prevent us from doing any work after the driver went away. This was fine before mac80211 had any suspend support. However, now we want to flush this workqueue in suspend(). Because the thread for a freezeable workqueue is stopped before the device class suspend() is called, flush_workqueue() will hang in the suspend-to-disk case. Converting it back to a non-freezeable queue will keep suspend from hanging. Moreover, since we flush the workqueue under RTNL and userspace is stopped, there won't be any new work in the workqueue until after resume. Thus we still don't have to worry about pinging the AP without hardware. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: Fixed BSSID handling revisitedAlina Friedrichsen2009-01-29
| | | | | | | | | | | | | | | | | | | | This patch cleanup the fixed BSSID handling, that ieee80211_sta_set_bssid() works like ieee80211_sta_set_ssid(). So that the BSSID is only a second selection criterion besides the SSID. This allows us to create new IBSS networks with fixed BSSIDs, which was broken before. In the second version of this patch the handling of the stupid merges to the same BSSID is moved out to get reworked into an other patch. And this version hopefully solves the problems with some low-level drivers and re-adds the config BSSID warning to help debugging the low-level drivers. Much thanks to all who have helped testing! :) Signed-off-by: Alina Friedrichsen <x-alina@gmx.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: allow mac80211 drivers to get to struct ieee80211_hw from wiphyLuis R. Rodriguez2009-01-29
| | | | | | | | | | | | If a driver is given a wiphy and it wants to get to its private mac80211 driver area it can use wiphy_to_ieee80211_hw() to get first to its ieee80211_hw and then access the private structure via hw->priv. The wiphy_priv() is already being used internally by mac80211 and drivers should not use this. This can be helpful in a drivers reg_notifier(). Signed-off-by: Luis R.

* cfg80211: Allow for strict regulatory settingsLuis R. Rodriguez2009-01-29
| | | | | | | | | | | | | | | | | This allows drivers to request strict regulatory settings to be applied to its devices. This is desirable for devices where proper calibration and compliance can only be gauranteed for for the device's programmed regulatory domain. Regulatory domain settings will be ignored until the device's own regulatory domain is properly configured. If no regulatory domain is received only the world regulatory domain will be applied -- if OLD_REG (default to "US") is not enabled. If OLD_REG behaviour is not acceptable to drivers they must update their wiphy with a custom reuglatory prior to wiphy registration. Signed-off-by: Luis R.

| | | | | | | | | | Drivers may need more information than just who set the last regulatory domain, as such lets just pass the last regulatory_request receipt.

| | | | | | | | | | | We ignore regulatory hints for the same alpha2 if we already have processed the same alpha2 on the current regulatory domain.

* mac80211: Fix drop-unencrypted for management framesJouni Malinen2009-01-29
| | | | | | | | | | | | | | | | | ADDBA request Action frame was sent out before 4-way handshake was completed and the initial 802.11w code ended up dropping the frame even if MFP was not enabled. While the sending of Action frames this early is not really a good idea (will break with MFP enabled), we should not break this for the MFP disabled case. This patch fixes ieee80211_tx_h_select_key() not to drop management frames if MFP is disabled. If MFP is enabled, Action frames will be dropped before keys are set per IEEE 802.11w/D7.0. Other robust management frames (i.e., Deauthentication and Disassociation frames) are allowed unprotected prior to key configuration.

* nl80211: New command for adding extra IE(s) into management framesJouni Malinen2009-01-29
| | | | | | | | | | | | | | | | A new nl80211 command, NL80211_CMD_SET_MGMT_EXTRA_IE, can be used to add arbitrary IE data into the end of management frames. The interface allows extra IEs to be configured for each management frame subtype, but only some of them (ProbeReq, ProbeResp, Auth, (Re)AssocReq, Deauth, Disassoc) are currently accepted in mac80211 implementation. This makes it easier to implement IEEE 802.11 extensions like WPS and FT that add IE(s) into some management frames. In addition, this can be useful for testing and experimentation purposes.
