cfg80211: process events caused by suspend before suspending

2016-10-26T05:59:52Z

When suspending without WoWLAN, cfg80211 will ask drivers to disconnect. Even when the driver does this synchronously, and immediately returns with a notification, cfg80211 schedules the handling thereof to a workqueue, and may then call back into the driver when the driver was already suspended/ing. Fix this by processing all events caused by cfg80211_leave_all() directly after that function returns. The driver still needs to do the right thing here and wait for the firmware response, but that is - at least - true for mwifiex where this occurred.

cfg80211: remove unnecessary pointer-of

2016-09-15T14:46:20Z

For an array, there's no need to use &array, so just use the plain wiphy->addresses[i].addr here to silence smatch. Signed-off-by: Johannes Berg

cfg80211: make wdev_list accessible to drivers

2016-05-12T09:16:40Z

There's no harm in having drivers read the list, since they can use RCU protection or RTNL locking; allow this to not require each and every driver to also implement its own bookkeeping. Signed-off-by: Johannes Berg

cfg80211: Switch to PM ops

2015-05-20T13:00:12Z

Use dev_pm_ops instead of the legacy suspend/resume callbacks for the wiphy class suspend and resume operations. Signed-off-by: Lars-Peter Clausen Signed-off-by: Johannes Berg

net: wireless: convert class code to use dev_groups

2013-07-25T23:34:40Z

The dev_attrs field of struct class is going away soon, dev_groups should be used instead. This converts the networking wireless class code to use the correct field. Reviewed-by: Johannes Berg Cc: John W. Linville Signed-off-by: Greg Kroah-Hartman

cfg80211: fix compilation warning for cfg80211_leave_all()

2013-06-24T13:57:32Z

The following compilation issue popped up moving from v3.10-rc1 to v3.10-rc6 after merging wireless-testing. net/wireless/sysfs.c:86:13: error: 'cfg80211_leave_all' defined but not used [-Werror=unused-function] The function is only called when CONFIG_PM is enabled. Moving the function under CONFIG_PM as well. Signed-off-by: Arend van Spriel Signed-off-by: Johannes Berg

cfg80211: make WoWLAN configuration available to drivers

2013-05-27T13:10:58Z

Make the current WoWLAN configuration available to drivers at runtime. This isn't really useful for the normal WoWLAN behaviour and accessing it can also be racy, but drivers may use it for testing the WoWLAN device behaviour while the host stays up & running to observe the device.

cfg80211/mac80211: disconnect on suspend

2013-03-06T15:35:55Z

If possible that after suspend, cfg80211 will receive request to disconnect what require action on interface that was removed during suspend. Problem can manifest itself by various warnings similar to below one: WARNING: at net/mac80211/driver-ops.h:12 ieee80211_bss_info_change_notify+0x2f9/0x300 [mac80211]() wlan0: Failed check-sdata-in-driver check, flags: 0x4 Call Trace: [] warn_slowpath_fmt+0x33/0x40 [] ieee80211_bss_info_change_notify+0x2f9/0x300 [mac80211] [] ieee80211_recalc_ps_vif+0x2a/0x30 [mac80211] [] ieee80211_set_disassoc+0xf6/0x500 [mac80211] [] ieee80211_mgd_deauth+0x1f1/0x280 [mac80211] [] ieee80211_deauth+0x16/0x20 [mac80211] [] cfg80211_mlme_down+0x70/0xc0 [cfg80211] [] __cfg80211_disconnect+0x1b1/0x1d0 [cfg80211] To fix the problem disconnect from any associated network before suspend. User space is responsible to establish connection again after resume. This basically need to be done by user space anyway, because associated stations can go away during suspend (for example NetworkManager disconnects on suspend and connect on resume by default). Patch also handle situation when driver refuse to suspend with wowlan configured and try to suspend again without it. Signed-off-by: Stanislaw Gruszka Signed-off-by: Johannes Berg
