My commit f2d9d270 ("mac80211: support VHT association") introduced a very stupid bug: the loop to downgrade the channel width never attempted to actually use it again so it would downgrade all the way to 20_NOHT. Fix it. Signed-off-by: NJohannes Berg <johannes.berg@intel.com>

Since: commit b23b025f Author: Ben Greear <greearb@candelatech.com> Date: Fri Feb 4 11:54:17 2011 -0800 mac80211: Optimize scans on current operating channel. we do not disable PS while going back to operational channel (on ieee80211_scan_state_suspend) and deffer that until scan finish. But since we are allowed to send frames, we can send a frame to AP without PM bit set, so disable PS on AP side. Then when we switch to off-channel (in ieee80211_scan_state_resume) we do not enable PS. Hence we are off-channel with PS disabled, frames are not buffered by AP. To fix remove offchannel_ps_disable argument and always enable PS when going off-channel and disable it when going on-channel, like it was before.

During FT roaming, wpa_supplicant attempts to set the key before association. This used to be rejected, but as a side effect of my commit 66e67e41 ("mac80211: redesign auth/assoc") the key was accepted causing hardware crypto to not be used for it as the station isn't added to the driver yet. It would be possible to accept the key and then add it to the driver when the station has been added. However, this may run into issues with drivers using the state- based station adding if they accept the key only after association like it used to be. For now, revert to the behaviour from before the auth and assoc change.

When AP's SSID is hidden the BSS can appear several times in cfg80211's BSS list: once with a zero-length SSID that comes from the beacon, and once for each SSID from probe reponses. Since the mac80211 stores its data in ieee80211_bss which is embedded into cfg80211_bss, mac80211's data will be duplicated too. This becomes a problem when a driver needs the dtim_period since this data exists only in the beacon's instance in cfg80211 bss table which isn't the instance that is used when associating. Remove the DTIM period from the BSS table and track it explicitly to avoid this problem.

This is a very old bug, but there's nothing that prevents the timer from running while the module is being removed when we only do del_timer() instead of del_timer_sync().

Unfortunately, commit b22cfcfc, intended to speed up roaming by avoiding the synchronize_rcu() broke AP/mesh modes as it moved some code into that work item that will still call into the driver at a time where it's no longer expected to handle this: after the AP or mesh has been stopped. To fix this problem remove the per-station work struct, maintain a station cleanup list instead and flush this list when stations are flushed. To keep this patch smaller for stable, do this when the stations are flushed (sta_info_flush()). This unfortunately brings back the original roaming delay; I'll fix that again in a separate patch. Also, Ben reported that the original commit could sometimes (with many interfaces) cause long delays when an interface is set down, due to blocking on flush_workqueue(). Since we now maintain the cleanup list, this particular change of the original patch can be reverted.

Introduce a field per_bio_data_size in struct dm_target. Targets can set this field in the constructor. If a target sets this field to a non-zero value, "per_bio_data_size" bytes of auxiliary data are allocated for each bio submitted to the target. These data can be used for any purpose by the target and help us improve performance by removing some per-target mempools. Per-bio data is accessed with dm_per_bio_data. The argument data_size must be the same as the value per_bio_data_size in dm_target. If the target has a pointer to per_bio_data, it can get a pointer to the bio with dm_bio_from_per_bio_data() function (data_size must be the same as the value passed to dm_per_bio_data).

Add WRITE SAME support to dm-io and make it accessible to dm_kcopyd_zero(). dm_kcopyd_zero() provides an asynchronous interface whereas the blkdev_issue_write_same() interface is synchronous.
