2013-01-03mac80211: warn if unexpectedly removing stationsJohannes Berg1-5/+7
When an interface is brought down it must have been disconnected (or similar) in all modes other than WDS, so warn if any stations were removed in other modes. Tested-by: Ben Greear <[email protected]> Signed-off-by: Johannes Berg <[email protected]>
2013-01-03mac80211: remove final sta_info_flush()Johannes Berg7-30/+16
When all interfaces have been removed, there can't be any stations left over, so there's no need to flush again. Remove this, and all code associated with it, which also simplifies the function. Tested-by: Ben Greear <[email protected]> Signed-off-by: Johannes Berg <[email protected]>

2013-01-03mac80211: fix dtim_period in hidden SSID AP associationJohannes Berg3-37/+55
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.

2013-01-03mac80211: use del_timer_sync for final sta cleanup timer deletionJohannes Berg1-1/+1
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(). The timer should normally not be running at this point, but it's not clearly impossible (or we could just remove this.)

2013-01-03mac80211: fix station destruction in AP/mesh modesJohannes Berg4-17/+62
Unfortunately, commit b22cfcfcae5b, 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.

wlc_lcnphy_rx_iq_cal_gain is called during initialization, i. e. when executing brcms_up. But brcms_up is called from brcms_ops_start while the latter holds a spin lock.

2013-01-02carl9170: fix -EINVAL bailout during init with !CONFIG_MAC80211_MESHChristian Lamparter1-1/+5
Sean reported that as of 3.7, his AR9170 device no longer works because the driver fails during initialization. He noted this is due to: "In carl9170/fw.c, ar->hw->wiphy is tagged with NL80211_IFTYPE_MESH_POINT support if the firmware has Content after Beacon Queuing. This is both in interface_modes and the only iface_combinations entry. If CONFIG_MAC80211_MESH is not set, ieee80211_register_hw removes NL80211_IFTYPE_MESH_POINT from interface_modes, but not iface_combinations. wiphy_register then checks to see if every interface type in every interface combination is in interface_modes. NL80211_IFTYPE_MESH_POINT was removed, so you get a WARN_ON warning and it returns -EINVAL, giving up." Unfortunately, the iface_combination (types) feature bitmap in ieee80211_iface_limit is part of a const member in the ieee80211_iface_combination struct. Hence, the MESH_POINT feature flag can't be masked by wiphy_register in the same way as interface_modes in ieee80211_register_hw.

2012-12-21dm snapshot: do not use map_contextMikulas Patocka1-13/+23
Eliminate struct map_info from dm-snap. map_info->ptr was used in dm-snap to indicate if the bio was tracked. If map_info->ptr was non-NULL, the bio was linked in tracked_chunk_hash. This patch removes the use of map_info->ptr. We determine if the bio was tracked based on hlist_unhashed(&c->node). If hlist_unhashed is true, the bio is not tracked, if it is false, the bio is tracked. Signed-off-by: Mikulas Patocka <[email protected]> Signed-off-by: Alasdair G Kergon <[email protected]>
2012-12-21dm thin: dont use map_contextMikulas Patocka1-36/+13
This patch removes endio_hook_pool from dm-thin and uses per-bio data instead. This patch removes any use of map_info in preparation for the next patch that removes map_info from bio-based device mapper.

2012-12-21dm raid1: dont use map_contextMikulas Patocka1-9/+13
Don't use map_info any more in dm-raid1. map_info was used for writes to hold the region number. For this purpose we add a new field dm_bio_details to dm_raid1_bio_record. map_info was used for reads to hold a pointer to dm_raid1_bio_record (if the pointer was non-NULL, bio details were saved; if the pointer was NULL, bio details were not saved). We use dm_raid1_bio_record.details->bi_bdev for this purpose. If bi_bdev is NULL, details were not saved, if bi_bdev is non-NULL, details were saved.

2012-12-21dm raid1: rename read_record to bio_recordMikulas Patocka1-11/+11
