Fix the tests so they respect the constness of the funcs array and also make use of the new location of the per-func state data. Fixes: 82182ad7b46e ('livepatch: do not use .livepatch.funcs section to store internal state') Signed-off-by: Roger Pau Monné Acked-by: Andrew Cooper Reviewed-by: Ross Lagerwall --- I will see about getting those tests build in gitlab, in the meantime we should take this fix in order to unblock osstest. --- xen/test/livepatch/xen_action_hooks.c | 12 +++++----- xen/test/livepatch/xen_action_hooks_marker.c | 20 ++++++++++------- xen/test/livepatch/xen_action_hooks_noapply.c | 22 +++++++++++-------- xen/test/livepatch/xen_action_hooks_nofunc.c | 6 ++--- .../livepatch/xen_action_hooks_norevert.c | 22 +++++++++++-------- xen/test/livepatch/xen_prepost_hooks.c | 8 +++---- xen/test/livepatch/xen_prepost_hooks_fail.c | 2 +- 7 files changed, 53 insertions(+), 39 deletions(-) diff --git a/xen/test/livepatch/xen_action_hooks.c b/xen/test/livepatch/xen_action_hooks.c index 39b531302731..fa0b3ab35f38 100644 --- a/xen/test/livepatch/xen_action_hooks.c +++ b/xen/test/livepatch/xen_action_hooks.c @@ -26,9 +26,10 @@ static int apply_hook(livepatch_payload_t *payload) for (i = 0;
