  commit e1364e05f92d6c2f12cc77f100cea584354c66cb
  Author: Jan Beulich <jbeulich@xxxxxxxx>

      evtchn/x86: enforce correct upper limit for 32-bit guests
      
      The recording of d->max_evtchns in evtchn_2l_init(), in particular with
      the limited set of callers of the function, is insufficient. Neither for
      PV nor for HVM guests the bitness is known at domain_create() time, yet
      the upper bound in 2-level mode depends upon guest bitness. Recording
      too high a limit "allows" x86 32-bit domains to open not properly usable
      event channels, management of which (inside Xen) would then result in
      corruption of the shared info and vCPU info structures.
      
      Keep the upper limit dynamic for the 2-level case, introducing a helper
      function to retrieve the effective limit. This helper is now supposed to
      be private to the event channel code. The used in do_poll() and
      domain_dump_evtchn_info() weren't consistent with port uses elsewhere
      and hence get switched to port_is_valid().
      
      Furthermore FIFO mode's setup_ports() gets adjusted to loop only up to
      the prior ABI limit, rather than all the way up to the new one.
      
      Finally a word on the change to do_poll(): Accessing ->max_evtchns
      without holding a suitable lock was never safe, as it as well as
      ->evtchn_port_ops may change behind do_poll()'s back. Using
      port_is_valid() instead widens some the window for potential abuse,
      until we've dealt with the race altogether (see XSA-343).
      
      This is XSA-342.

  commit e1364e05f92d6c2f12cc77f100cea584354c66cb
  Author: Jan Beulich <jbeulich@xxxxxxxx>
  Date:   Tue Sep 22 16:24:29 2020 +0200
  
      evtchn/x86: enforce correct upper limit for 32-bit guests
      
      The recording of d->max_evtchns in evtchn_2l_init(), in particular with
      the limited set of callers of the function, is insufficient. Neither for
      PV nor for HVM guests the bitness is known at domain_create() time, yet
      the upper bound in 2-level mode depends upon guest bitness. Recording
      too high a limit "allows" x86 32-bit domains to open not properly usable
      event channels, management of which (inside Xen) would then result in
      corruption of the shared info and vCPU info structures.
      
      Keep the upper limit dynamic for the 2-level case, introducing a helper
      function to retrieve the effective limit. This helper is now supposed to
      be private to the event channel code. The used in do_poll() and
      domain_dump_evtchn_info() weren't consistent with port uses elsewhere
      and hence get switched to port_is_valid().
      
      Furthermore FIFO mode's setup_ports() gets adjusted to loop only up to
      the prior ABI limit, rather than all the way up to the new one.
      
      Finally a word on the change to do_poll(): Accessing ->max_evtchns
      without holding a suitable lock was never safe, as it as well as
      ->evtchn_port_ops may change behind do_poll()'s back. Using
      port_is_valid() instead widens some the window for potential abuse,
      until we've dealt with the race altogether (see XSA-343).
      
      This is XSA-342.
