commit 902377b690f42ddf44ae91c4b0751d597f1cd694 Author: Roger Pau Monne <roger.pau@xxxxxxxxxx> AuthorDate: Tue Nov 28 18:41:31 2023 +0100 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Wed Nov 29 10:46:42 2023 +0000 xen/livepatch: fix livepatch tests The current set of in-tree livepatch tests in xen/test/livepatch started failing after the constify of the payload funcs array, and the movement of the status data into a separate array. 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 <roger.pau@xxxxxxxxxx> Acked-by: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> Reviewed-by: Ross Lagerwall <ross.lagerwall@xxxxxxxxxx> --- 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 +++--- xen/test/livepatch/xen_action_hooks_norevert.c | 24 ++++++++++++++---------- xen/test/livepatch/xen_prepost_hooks.c | 8 ++++---- xen/test/livepatch/xen_prepost_hooks_fail.c | 2 +- 7 files changed, 54 insertions(+), 40 deletions(-) diff --git a/xen/test/livepatch/xen_action_hooks.c b/xen/test/livepatch/xen_action_hooks.c index 39b5313027..fa0b3ab35f 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;
