       "These fix three issues introduced recently, two related to defects in
        ACPI tables supplied by the platform firmware and one cause by a
        thermal core change that went too far:
      
         - Prevent the thermal core from failing the registration of a cooling
           device if its .get_cur_state() reports an incorrect state to start
           with which may happen for fans handled through firmware-supplied
           AML in ACPI tables (Rafael Wysocki)
      
         - Make the ACPI thermal zone driver initialize all trip points with
           temperature of 0 centigrade and below as invalid because such trip
           point temperatures do not make sense on systems with ACPI thermal
           control and they cause performance regressions due to permanent
           thermal mitigations to occur (Rafael Wysocki)
      
         - Restore passive polling management in the Step-Wise thermal
           governor that uses it to ensure that all cooling devices used for
           thermal mitigation will go back to their initial states eventually

      io_uring: fix cancellation overwriting req->flags · f4a1254f
      Pavel Begunkov authored
      Only the current owner of a request is allowed to write into req->flags.
      Hence, the cancellation path should never touch it. Add a new field
      instead of the flag, move it into the 3rd cache line because it should
      always be initialised. poll_refs can move further as polling is an
      involved process anyway.
      
      It's a minimal patch, in the future we can and should find a better
      place for it and remove now unused REQ_F_CANCEL_SEQ.
      
      Fixes: 521223d7 ("io_uring/cancel: don't default to setting req->work.cancel_seq")

      thermal: gov_step_wise: Restore passive polling management · b6846826
      Rafael J. Wysocki authored
      Consider a thermal zone with one passive trip point, a cooling device
      with 3 states (0, 1, 2) bound to it, passive polling enabled (nonzero
      passive_delay_jiffies) and no regular polling (polling_delay_jiffies
      equal to 0) that is managed by the Step-Wise governor.  Suppose that
      the initial state of the cooling device is 0 and the zone temperature
      is below the trip point to start with.
      
      When the trip point is crossed, tz->passive is incremented by the
      thermal core and the governor's .manage() callback is invoked.  It
      sets 'throttle' to 'true' for the trip in question and
      get_target_state() returns 1 for the instance corresponding to the
      cooling device (say that 'upper' and 'lower' are set to 2 and 0 for
      it, respectively), so its state changes to 1.
      
      Passive polling is still active for the zone, so next time the
      temperature is updated, the governor's .manage() callback will be
      invoked again.  If the temperature is still rising, it will change
      the state of the cooling device to 2.
      
      Now suppose that next time the zone temperature is updated, it falls
      below the trip point, so tz->passive is decremented for the zone (say
      it becomes 0 then) and the governor's .manage() callbacks runs.
      
      It finds that the temperature trend for the zone is 'falling' and
      'throttle' will be set to 'false' for the trip in question, so the
      cooling device's state will be changed to 1.  However, because
      tz->polling is 0 for the zone, the governor's .manage() callback
      may not be invoked again for a long time and the cooling device's
      state will not be reset back to 0.
      
      This can happen because commit 042a3d80 ("thermal: core: Move
      passive polling management to the core") removed passive polling
      management from the Step-Wise governor.
      
      Before that change, thermal_zone_trip_update() would bump up
      tz->passive when changing the target state for a thermal instance
      from "no target" to a specific value and it would drop tz->passive
      when changing it back to "no target" which would cause passive
      polling to be active for the zone until the governor has reset the
      states of all cooling devices.  In particular, in the example above
      tz->passive would be incremented when changing the state of the
      cooling device from 0 to 1 and then it would be still nonzero when
      the state of the cooling device was changed from 2 to 1.
      
      To prevent this problem from occurring, restore the passive polling
      management in the Step-Wise governor by partially reverting the
      commit in question and update the comment in the restored code
      to explain its role more clearly.
      
      Fixes: 042a3d80 ("thermal: core: Move passive polling management to the core")

      netfilter: Use flowlabel flow key when re-routing mangled packets · 6f8f132c
      Florian Westphal authored
      'ip6 dscp set $v' in an nftables outpute route chain has no effect.
      While nftables does detect the dscp change and calls the reroute hook.
      But ip6_route_me_harder never sets the dscp/flowlabel:
      flowlabel/dsfield routing rules are ignored and no reroute takes place.
      
      Thanks to Yi Chen for an excellent reproducer script that I used
      to validate this change.
