[Bug 1709905] Re: stress-ng 0.08.10 fails to compile on SLES11 SP4

[Hubba]

I have managed to compile 0.09.00 by renaming F_OWNER_PGRP back to
F_OWNER_GID which I believe from some reading is what this was called on
older Linux distros
(https://gitlab.collabora.com/martyn/linux/commit/978b4053aefd422713f289f2a315ce2acba62018)
so I did on the source:

sed -i 's/F_OWNER_PGRP/F_OWNER_GID/g' stress-fcntl.c

Not sure yet as that has any negative impact.

Best regards
Hubba

You are right. There is no such bug in 3.13.0-92 kernel for Trusty.

>>This appears to be fixed in Xenial (16.04) already. Can you confirm?

Yes, migration of Ubuntu 16.04 4.4.0-21-generic #37 works fine.

xen/events: Mask a moving irq

BugLink: http://bugs.launchpad.net/bugs/1571034

commit ff1e22e7a638a0782f54f81a6c9cb139aca2da35 upstream.

Moving an unmasked irq may result in irq handler being invoked on both
source and target CPUs.

With 2-level this can happen as follows:

On source CPU:
evtchn_2l_handle_events() ->
generic_handle_irq() ->
handle_edge_irq() ->
   eoi_pirq():
   irq_move_irq(data);

   /* WE ARE HERE */

   if (VALID_EVTCHN(evtchn))
   clear_evtchn(evtchn);

If at this moment target processor is handling an unrelated event in
evtchn_2l_handle_events()'s loop it may pick up our event since target's
cpu_evtchn_mask claims that this event belongs to it *and* the event is
unmasked and still pending. At the same time, source CPU will continue
executing its own handle_edge_irq().

With FIFO interrupt the scenario is similar: irq_move_irq() may result
in a EVTCHNOP_unmask hypercall which, in turn, may make the event
pending on the target CPU.

We can avoid this situation by moving and clearing the event while
keeping event masked.
