mac80211: revert on-channel work optimisations

2012-01-26T00:13:37Z

commit e76aadc572288a158ae18ae1c10fe395c7bca066 upstream. Backport note: This patch it's a full revert of commit b23b025f "mac80211: Optimize scans on current operating channel.". On upstrem revert e76aadc5 we keep some bits from that commit, which are needed for upstream version of mac80211. The on-channel work optimisations have caused a number of issues, and the code is unfortunately very complex and almost impossible to follow. Instead of attempting to put in more workarounds let's just remove those optimisations, we can work on them again later, after we change the whole auth/assoc design. This should fix rate_control_send_low() warnings, see RH bug 731365. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville Signed-off-by: Stanislaw Gruszka Signed-off-by: Greg Kroah-Hartman

mac80211: config hw when going back on-channel

2011-11-02T19:23:11Z

When going back on-channel, we should reconfigure the hw iff the hardware is not already configured to the operational channel. Signed-off-by: Eliad Peller Cc: stable@kernel.org # 2.6.39+ Signed-off-by: John W. Linville

mac80211: fix remain_off_channel regression

2011-11-02T19:23:11Z

The offchannel code is currently broken - we should remain_off_channel if the work was started, and the work's channel and channel_type are the same as local->tmp_channel and local->tmp_channel_type. However, if wk->chan_type and local->tmp_channel_type coexist (e.g. have the same channel type), we won't remain_off_channel. This behavior was introduced by commit da2fd1f ("mac80211: Allow work items to use existing channel type.")

mac80211: fix offchannel TX cookie matching

2011-10-11T20:41:08Z

When I introduced in-kernel off-channel TX I introduced a bug -- the work can't be canceled again because the code clear the skb pointer. Fix this by keeping track separately of whether TX status has already been reported.

mac80211: Send the management frame at requested rate

2011-09-27T18:34:10Z

Whenever the scan request or tx_mgmt is requesting not to use CCK rate for managemet frames through NL80211_ATTR_TX_NO_CCK_RATE attribute, then mac80211 should select appropriate least non-CCK rate. This could help to send P2P probes and P2P action frames at non 11b rates without diabling 11b rates globally. Cc: Jouni Malinen Signed-off-by: Rajkumar Manoharan Signed-off-by: John W. Linville

mac80211: Remove unnecessary OOM logging messages

2011-09-13T19:45:02Z

Removing unnecessary messages saves code and text. Site specific OOM messages are duplications of a generic MM out of memory message and aren't really useful, so just delete them. Signed-off-by: Joe Perches Signed-off-by: John W. Linville

mac80211: sync driver before TX

2011-07-20T19:04:35Z

In P2P client mode, the GO (AP) to connect to might have periods of time where it is not available due to powersave. To allow the driver to sync with it and send frames to the GO only when it is available add a new callback tx_sync (and the corresponding finish_tx_sync). These callbacks can sleep unlike the actual TX. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: implement scan supported rates

2011-07-19T20:50:00Z

Scanning currently uses the TX rate mask to restrict the rate set, which is bogus. Make it use the new set of rates from userspace. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: Drop DS Channel PARAM in directed probe

2011-06-27T19:09:41Z

Do not send DS Channel parameter for directed probe requests in order to maximize the chance that we get a response. Some badly-behaved APs don't respond when this parameter is included. Signed-off-by: Paul Stewart Reviewed-by: Johannes Berg Signed-off-by: John W. Linville
