2020-08-03mac80211: Do not report beacon loss if beacon filtering enabledLoic Poulain
mac80211.h says: Beacon filter support is advertised with the IEEE80211_VIF_BEACON_FILTER interface capability. The driver needs to enable beacon filter support whenever power save is enabled, that is IEEE80211_CONF_PS is set. When power save is enabled, the stack will not check for beacon loss and the driver needs to notify about loss of beacons with ieee80211_beacon_loss(). Some controllers may want to dynamically enable the beacon filter capabilities on power save entry (CONF_PS) and disable it on exit. This is the case for the wcn36xx driver which only supports beacon filtering in PS mode (no CONNECTION_MONITOR support). When the mac80211 beacon monitor timer expires, the beacon filter flag must be checked again in case it as been changed in between (e.g. vif moved to PS mode).

2020-08-03netfilter: flowtable: Set offload timeout when adding flowRoi Dayan
On heavily loaded systems the GC can take time to go over all existing conns and reset their timeout. At that time other calls like from nf_conntrack_in() can call of nf_ct_is_expired() and see the conn as expired. To fix this when we set the offload bit we should also reset the timeout instead of counting on GC to finish first iteration over all conns before the initial timeout.

2020-08-03ceph: fix potential mdsc use-after-free crashXiubo Li
Make sure the delayed work stopped before releasing the resources. cancel_delayed_work_sync() will only guarantee that the work finishes executing if the work is already in the ->worklist. That means after the cancel_delayed_work_sync() returns, it will leave the work requeued if it was rearmed at the end. That can lead to a use after free once the work struct is freed. Fix it by flushing the delayed work instead of trying to cancel it, and ensure that the work doesn't rearm if the mdsc is stopping.
