2012-05-16mac80211: fix single queue driversJohannes Berg
My queue management rework broke drivers that don't have multiple AC queues and register a single queue only, causing a warning: WARNING: at net/mac80211/iface.c:162 ieee80211_check_queues This was due to filling the queues wrongly and then noticing the error when checking later.

2012-04-11mac80211: add improved HW queue controlJohannes Berg
mac80211 currently only supports one hardware queue per AC. This is already problematic for off-channel uses since if we go off channel while the BE queue is full and then try to send an off-channel frame the frame will never go out. This will become worse when we support multi-channel since then a queue on one channel might be full, but we have to stop the software queue for all channels. That is obviously not desirable. To address this problem allow drivers to register more hardware queues, and allow them to map them to virtual interfaces. When they stop a hardware queue the corresponding AC software queues on the correct interfaces will be stopped as well. Additionally, there's an off-channel queue to solve that problem and a per-interface after-DTIM beacon queue. This allows drivers to manage software queues closer to how the hardware works. Currently, there's a limit of 16 hardware queues. This may or may not be sufficient, we can adjust it as needed. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2012-04-11mac80211: add explicit monitor interface if neededJohannes Berg
The queue mapping redesign that I'm planning to do will break pure injection unless we handle monitor interfaces explicitly. One possible option would be to have the driver tell mac80211 about monitor mode queues etc., but that would duplicate the API since we already need to have queue assignments handled per virtual interface. So in order to solve this, have a virtual monitor interface that is added whenever all active vifs are monitors. We could also use the state of one of the monitor interfaces, but managing that would be complicated, so allocate separate state.

2012-02-27mac80211: fix auth/assoc data & timer leakJohannes Berg
When removing an interface while it is in the process of authenticating or associating, we leak the auth_data or assoc_data, and leave the timer pending. The timer then crashes the system when it fires as its data is gone. Fix this by explicitly deleting all the data when the interface is removed. This uncovered another bug -- this problem should have been detected by the sta_info_flush() warning but that function doesn't ever return non-zero, I'll fix that in a separate patch.

2012-02-21mac80211: Fix a warning on changing to monitor mode from STAMohammed Shafi Shajakhan
nothing needs to be done for monitor/AP_VLAN mode on calling ieee80211_bss_info_change_notify -> drv_bss_info_changed with the change flag 'BSS_CHANGED_IDLE'. 'wl1271' seems to use BSS_CHANGED_IDLE only for STA and IBSS mode. further the non-idle state of the monitor mode is taken care by the 'count' variable which counts non-idle interfaces. ieee80211_idle_off(local, "in use") will be called. this fixes the following WARNING when we have initially STA mode (network manager running) and not associated, and change it to monitor mode with network manager disabled and bringing up the monitor mode. this changes the idle state from 'true' (STA unassociated) to 'false' (MONITOR mode) exposed by the commit 405385f8ce7a2ed8f82e216d88b5282142e1288b "mac80211: set bss_conf.idle when vif is connected" WARNING: net/mac80211/main.c:212 ieee80211_bss_info_change_notify+0x1cf/0x330 [mac80211]() Hardware name: 64756D6 Pid: 3835, comm: ifconfig Tainted: G O 3.3.0-rc3-wl #9 Call Trace: [<c0133b02>] warn_slowpath_common+0x72/0xa0 [<fc8e8c3f>] ? ieee80211_bss_info_change_notify+0x1cf/0x330 [mac80211] [<fc8e8c3f>] ? ieee80211_bss_info_change_notify+0x1cf/0x330 [mac80211] [<c0133b52>] warn_slowpath_null+0x22/0x30 [<fc8e8c3f>] ieee80211_bss_info_change_notify+0x1cf/0x330 [mac80211] [<fc8f9de3>] __ieee80211_recalc_idle+0x113/0x430 [mac80211] [<fc8fabc6>] ieee80211_do_open+0x156/0x7e0 [mac80211] [<fc8f8a25>] ? ieee80211_check_concurrent_iface+0x25/0x180 [mac80211] [<c015dd9f>] ? raw_notifier_call_chain+0x1f/0x30 [<fc8fb290>] ieee80211_open+0x40/0x80 [mac80211] [<c05894f6>] __dev_open+0x96/0xe0 [<c068fba5>] ? _raw_spin_unlock_bh+0x35/0x40 [<c05881d9>] __dev_change_flags+0x109/0x170 [<c0589423>] dev_change_flags+0x23/0x60 [<c05f3770>] devinet_ioctl+0x6a0/0x770 ieee80211 phy0: device no longer idle - in use Cc: Eliad Peller <eliad@wizery.com> Signed-off-by: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com> Signed-off-by: John W.

However, some devices that implement hw scan might not need going idle-off in order to perform a hw scan, and thus saving some energy and simplifying their state machine.

This is the second part of the auth/assoc redesign, the mac80211 part. This moves the auth/assoc code out of the work abstraction and into the MLME, so that we don't flip channels all the time etc. The only downside is that when we are associated, we need to drop the association in order to create a connection to another AP, but for most drivers this is actually desirable and the ability to do was never used by any applications.

2012-01-30mac80211: station state transition error handlingJohannes Berg
In the future, when we start notifying drivers, state transitions could potentially fail. To make it easier to distinguish between programming bugs and driver failures: * rename sta_info_move_state() to sta_info_pre_move_state() which can only be called before the station is inserted (and check this with a new station flag). * rename sta_info_move_state_checked() to just plain sta_info_move_state(), as it will be the regular function that can fail for more than just one reason (bad transition or an error from the driver) This makes the programming model easier -- one of the functions can only be called before insertion and can't fail, the other can fail.

2011-12-15mac80211: refactor station state transitionsJohannes Berg
Station entries can have various states, the most important ones being auth, assoc and authorized. This patch prepares us for telling the driver about these states, we don't want to confuse drivers with strange transitions, so with this we enforce that they move in the right order between them (back and forth); some transitions might happen before the driver even knows about the station, but at least runtime transitions will be ordered correctly. As a consequence, IBSS and MESH stations will now have the ASSOC flag set (so they can transition to AUTHORIZED), and we can get rid of a special case in TX processing. When freeing a station, unwind the state so that other parts of the code (or drivers later) can rely on the transitions. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

Convert all rcu_assign_pointer of NULL value. //smpl @@ expression P; @@ - rcu_assign_pointer(P, NULL) + RCU_INIT_POINTER(P, NULL) // </smpl> Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Acked-by: Paul E.

2011-07-28net: Audit drivers to identify those needing IFF_TX_SKB_SHARING clearedNeil Horman
After the last patch, We are left in a state in which only drivers calling ether_setup have IFF_TX_SKB_SHARING set (we assume that drivers touching real hardware call ether_setup for their net_devices and don't hold any state in their skbs. There are a handful of drivers that violate this assumption of course, and need to be fixed up. This patch identifies those drivers, and marks them as not being able to support the safe transmission of skbs by clearning the IFF_TX_SKB_SHARING flag in priv_flags Signed-off-by: Neil Horman <nhorman@tuxdriver.com> CC: Karsten Keil <isdn@linux-pingi.de> CC: "David S.

2011-07-11mac80211: allocate only one RX queueJohannes Berg
We don't have multiple RX queues, so there's no use in allocating multiple, use alloc_netdev_mqs() to allocate multiple TX but only one RX queue. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

This partially reverts 1c5cae815d19ffe02bdfda1260949ef2b1806171, because the netdev name is copied into sdata->name, which is used for debugging messages, for example. Otherwise, we get messages like this: wlan%d: authenticated Signed-off-by: Thadeu Lima de Souza Cascardo <cascardo@holoscopio.com> Cc: Jiri Pirko <jpirko@redhat.com> Cc: David S.

2011-05-16mac80211: abort scan_work immediately when the device goes downRajkumar Manoharan
As long as no delay is required b/w channel change, scan work is proceeding without scheduling a new work. In such case, we can not abort scan work when the card was unplugged. This patch completes the scanning immediately whenever the device goes down.

2011-05-16mac80211: sparse RCU annotationsJohannes Berg
This adds sparse RCU annotations to most of mac80211, only the mesh code remains to be done. Due the the previous patches, the annotations are pretty simple. The only thing that this actually changes is removing the RCU usage of key->sta in debugfs since this pointer isn't actually an RCU-managed pointer (it only has a single assignment done before the key even goes live). As that is otherwise harmless, I decided to make it part of this patch. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2011-05-05net: call dev_alloc_name from register_netdeviceJiri Pirko
Force dev_alloc_name() to be called from register_netdevice() by dev_get_valid_name(). That allows to remove multiple explicit dev_alloc_name() calls. The possibility to call dev_alloc_name in advance remains.
