From 50aa870ba2f7735f556e52d15f61cd0f359c4c0b Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Sun, 22 Jan 2023 04:04:50 -0500 Subject: selftests: kvm: move declaration at the beginning of main() Placing a declaration of evt_reset is pedantically invalid according to the C standard. While GCC does not really care and only warns with -Wpedantic, clang ignores the declaration altogether with an error: x86_64/xen_shinfo_test.c:965:2: error: expected expression struct kvm_xen_hvm_attr evt_reset = { ^ x86_64/xen_shinfo_test.c:969:38: error: use of undeclared identifier evt_reset vm_ioctl(vm, KVM_XEN_HVM_SET_ATTR, &evt_reset); ^ Reported-by: Yu Zhang Reported-by: Sean Christopherson Fixes: a79b53aaaab5 ("KVM: x86: fix deadlock for KVM_XEN_EVTCHN_RESET", 2022-12-28) Signed-off-by: Paolo Bonzini --- tools/testing/selftests/kvm/x86_64/xen_shinfo_test.c | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'tools/testing') diff --git a/tools/testing/selftests/kvm/x86_64/xen_shinfo_test.c b/tools/testing/selftests/kvm/x86_64/xen_shinfo_test.c index dae510c263b4..13c75dc18c10 100644 --- a/tools/testing/selftests/kvm/x86_64/xen_shinfo_test.c +++ b/tools/testing/selftests/kvm/x86_64/xen_shinfo_test.c @@ -434,6 +434,7 @@ static void *juggle_shinfo_state(void *arg) int main(int argc, char *argv[]) { struct timespec min_ts, max_ts, vm_ts; + struct kvm_xen_hvm_attr evt_reset; struct kvm_vm *vm; pthread_t thread; bool verbose; @@ -962,10 +963,8 @@ int main(int argc, char *argv[]) } done: - struct kvm_xen_hvm_attr evt_reset = { - .type = KVM_XEN_ATTR_TYPE_EVTCHN, - .u.evtchn.flags = KVM_XEN_EVTCHN_RESET, - }; + evt_reset.type = KVM_XEN_ATTR_TYPE_EVTCHN; + evt_reset.u.evtchn.flags = KVM_XEN_EVTCHN_RESET; vm_ioctl(vm, KVM_XEN_HVM_SET_ATTR, &evt_reset); alarm(0); -- cgit From c2c46b10d52624376322b01654095a84611c7e09 Mon Sep 17 00:00:00 2001 From: Vipin Sharma Date: Wed, 11 Jan 2023 10:34:08 -0800 Subject: KVM: selftests: Make reclaim_period_ms input always be positive reclaim_period_ms used to be positive only but the commit 0001725d0f9b ("KVM: selftests: Add atoi_positive() and atoi_non_negative() for input validation") incorrectly changed it to non-negative validation.
