2015-09-04arm/arm64: KVM: vgic: Move active state handling to flush_hwstateChristoffer Dall
We currently set the physical active state only when we *inject* a new pending virtual interrupt, but this is actually not correct, because we could have been preempted and run something else on the system that resets the active state to clear. This causes us to run the VM with the timer set to fire, but without setting the physical active state. The solution is to always check the LR configurations, and we if have a mapped interrupt in the LR in either the pending or active state (virtual), then set the physical active state.

2015-09-04mac80211: protect non-HT BSS when HT TDLS traffic existsAvri Altman
HT TDLS traffic should be protected in a non-HT BSS to avoid collisions. Therefore, when TDLS peers join/leave, check if protection is (now) needed and set the ht_operation_mode of the virtual interface according to the HT capabilities of the TDLS peer(s). This works because a non-HT BSS connection never sets (or otherwise uses) the ht_operation_mode; it just means that drivers must be aware that this field applies to all HT traffic for this virtual interface, not just the traffic within the BSS.

These cases were considered as (potentially) problematic: - 'perf script' with !sample_id_all, i.e. only non old kernels without perf_event_attr.sample_id_all. - intel_pt could be affected when decoding without timestamps, as the exit event is only used to flush out data which anyway gets flushed at the end of the session. - intel_bts also uses the exit event to flush data which would probably not cause errors as it would get flushed at the end of the session instead.

2015-09-03Input: evdev - do not report errors form flush()Takashi Iwai
We've got bug reports showing the old systemd-logind (at least system-210) aborting unexpectedly, and this turned out to be because of an invalid error code from close() call to evdev devices. close() is supposed to return only either EINTR or EBADFD, while the device returned ENODEV. logind was overreacting to it and decided to kill itself when an unexpected error code was received. What a tragedy. The bad error code comes from flush fops, and actually evdev_flush() returns ENODEV when device is disconnected or client's access to it is revoked. But in these cases the fact that flush did not actually happen is not an error, but rather normal behavior. For non-disconnected devices result of flush is also not that interesting as there is no potential of data loss and even if it fails application has no way of handling the error. Because of that we are better off always returning success from evdev_flush(). Also returning EINTR from flush()/close() is discouraged (as it is not clear how application should handle this error), so let's stop taking evdev->mutex interruptibly.
