* cfg80211/mac80211: extensible frame processingJohannes Berg2010-08-247-54/+147
| | | | | | | | | | | | | | | Allow userspace to register for more than just action frames by giving the frame subtype, and make it possible to use this in various modes as well. With some tweaks and some added functionality this will, in the future, also be usable in AP mode and be able to replace the cooked monitor interface currently used in that case.

* mac80211: remove unused don't-encrypt flagJohannes Berg2010-08-241-2/+0
| | | | | | | | | | | | | When MFP is disabled, action frames will not be encrypted since they are management frames and the only management frames that can then be encrypted are authentication frames. Therefore, setting the don't-encrypt flag on action frames is unnecessary. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: use cipher suite selectorsJohannes Berg2010-08-169-105/+75
| | | | | | | | | | | | | Currently, mac80211 translates the cfg80211 cipher suite selectors into ALG_* values. That isn't all too useful, and some drivers benefit from the distinction between WEP40 and WEP104 as well. Therefore, convert it all to use the cipher suite selectors.

* mac80211: allow drivers to request SM PS mode changeJohannes Berg2010-08-163-1/+36
| | | | | | | | | | | | | Sometimes drivers have more information than the stack about how their antennas/chains are used, and may require that the SM PS mode be changed. This could happen, for example, when detecting that the user disconnected an antenna. Thus this patch introduces API to allow drivers to request SM PS mode changes.

* mac80211: AMPDU rx reorder timeout timerChristian Lamparter2010-08-164-12/+97
| | | | | | | | | | | | | | | | | | | | | This patch introduces a new timer, which will release queued-up MPDUs from the reorder buffer, whenever they've waited for more than HT_RX_REORDER_BUF_TIMEOUT (which is at around 100 ms). The advantage of having a dedicated timer, instead of relying on a constant stream of freshly arriving aMPDUs to release the old ones, is particularly observable when even a small fraction of MPDUs are forever lost at low network speeds. Previously under these circumstances frames would become stuck in the reorder buffer and the network stack of both HT peers throttled back, instead of revving up and gunning the pipes.

| | | | | | | | | | | | When running in client mode and associating to an AP, the channel change is usually performed with the offchannel flag still set. However after the assoc is complete, the following channel change event is suppressed because the run time channel is already set to the operating channel.

* mac80211: support use of NAPI for bottom-half processingJohn W. Linville2010-08-163-0/+39
| | | | | | | | | | | | | | This patch implement basic infrastructure to support use of NAPI by mac80211-based hardware drivers. Because mac80211 devices can support multiple netdevs, a dummy netdev is used for interfacing with the NAPI code in the core of the network stack. That structure is hidden from the hardware drivers, but the actual napi_struct is exposed in the ieee80211_hw structure so that the poll routines in drivers can retrieve that structure. Hardware drivers can also specify their own weight value for NAPI polling. Signed-off-by: John W. Linville <linville@tuxdriver.com>

This is important for various kinds of calibration work, which takes longer to complete and should keep some persistent state, even if the channel temporarily changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts this commit. While in theory the change is correct the patch does not address current assumptions made by some drivers, one which is definitley affected is ath9k. Prior to this change the scan complete callback would be called after we returned to the home channel and configured the hardware RX filters. After this change we call the scan complete callback prior to both the hw config and the config filter. At least for ath9k this breaks quite a few assumptions on the callback, leading to disconnects to the AP after every scan making the driver pretty useless on STA mode. The goal behind this commit was to address the now understood spurious warnings from ath9k and mac80211_hwsim on scanning on two wiphys at the same time but we have now supressed these and will address this issue in the next kernel release. When fixing this for good next we must first review the other driver's dependence on this logic and perhaps consider removal of the scan complete callback all together.

| * mac80211: Fix key freeing to handle unlinked keysJouni Malinen2010-07-274-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Key locking simplification removed key->sdata != NULL verification from ieee80211_key_free(). While that is fine for most use cases, there is one path where this function can be called with an unlinked key (i.e., key->sdata == NULL && key->local == NULL). This results in a NULL pointer dereference with the current implementation. This is known to happen at least with FT protocol when wpa_supplicant tries to configure the key before association. Avoid the issue by passing in the local pointer to ieee80211_key_free(). In addition, do not clear the key from hw_accel or debugfs if it has not yet been added. At least the hw_accel one could trigger another NULL pointer dereference. Signed-off-by: Jouni Malinen <j@w1.fi> Reviewed-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

The reason is that the IBSS and station mode code have different locking orders for the cfg80211 wdev lock and the work struct (where "locking" implies running/canceling). Fix this by simply not canceling the work in the IBSS code, it is not necessary since when the REQ_RUN bit is cleared, the work will run without effect if it runs. When the interface is set down, it is flushed anyway, so there's no concern about it running after memory has been invalidated either. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=16419 Additionally, looking into this I noticed that there's a small window while the IBSS is torn down in which the work may be rescheduled and the REQ_RUN bit be set again after leave() has cleared it when a scan finishes at exactly the same time. Avoid that by setting the ssid_len to zero before clearing REQ_RUN which signals to the scan finish code that this interface is not active.

However, this is only relevant for station mode, since only then will any device send nullfunc frames and need to know whether they should be QoS frames or not. In other modes, there are (currently) no frames the device is supposed to send. When you now consider virtual interfaces, it becomes apparent that the current mechanism is inadequate since it enables/disables QoS on a global scale, where for nullfunc frames it has to be on a per-interface scale. Due to the above considerations, we can change the way mac80211 advertises the QoS state to drivers to only ever advertise it as "off" in station mode, and make it a per-BSS setting.

| * | | mac80211: remove wep dependencyJohn W. Linville2010-07-087-21/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current mac80211 code assumes that WEP is always available. If WEP fails to initialize, ieee80211_register_hw will always fail. In some cases (e.g. FIPS certification), the cryptography used by WEP is unavailable. However, in such cases there is no good reason why CCMP encryption (or even no link level encryption) cannot be used. So, this patch removes mac80211's assumption that WEP (and TKIP) will always be available for use. Signed-off-by: John W. Linville <linville@tuxdriver.com>
