Fix race between un-pausing vcpu and requesting vcpu pause
To ensure that we do not miss pause request sent while we were in paused state, or were exiting paused state, let's start using KVM_SET_SIGNAL_MASK. SIGRTMIN() + 0 signal will be blocked and thus is not delivered, and it will only be checked when KVM_RUN is being executed, reliably interrupting KVM_RUN. TEST=cargo test --features plugin; cargo test -p kvm; ./build_test BUG=chromium:800626 Change-Id: Iae67a411c23c2b14fbfcbc7d53d0bc86ec4b67d9 Signed-off-by: Dmitry Torokhov <dtor@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/944850 Reviewed-by: Zach Reizner <zachr@chromium.org>
