Both cryptodev_backend_set_throttle() and CryptoDevBackendClass::init()
can set their Error** argument. Do not ignore them, return early
on failure. Without that, running into another failure trips
error_setv()'s assertion. Use the ERRP_GUARD() macro as suggested
in commit ae7c80a7bd ("error: New macro ERRP_GUARD()").Cc: [email protected] Fixes: e7a775fd9f ("cryptodev: Account statistics") Fixes: 2580b452ff ("cryptodev: support QoS") Reviewed-by: zhenwei pi <[email protected]> Reviewed-by: Gonglei <[email protected]> Reviewed-by: Markus Armbruster <[email protected]> Signed-off-by: Philippe Mathieu-Daudé <[email protected]> --- backends/cryptodev.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/backends/cryptodev.c b/backends/cryptodev.c index e5006bd215..fff89fd62a 100644 --- a/backends/cryptodev.c +++ b/backends/cryptodev.c @@ -398,6 +398,7 @@ static void cryptodev_backend_set_ops(Object *obj, Visitor *v, static void cryptodev_backend_complete(UserCreatable *uc, Error **errp) { + ERRP_GUARD(); CryptoDevBackend *backend = CRYPTODEV_BACKEND(uc); CryptoDevBackendClass *bc = CRYPTODEV_BACKEND_GET_CLASS(uc); uint32_t services; @@ -406,11 +407,20 @@ cryptodev_backend_complete(UserCreatable *uc, Error **errp) QTAILQ_INIT(&backend->opinfos); value = backend->tc.buckets[THROTTLE_OPS_TOTAL].avg; cryptodev_backend_set_throttle(backend, THROTTLE_OPS_TOTAL, value, errp); + if (*errp) { + return; + } value = backend->tc.buckets[THROTTLE_BPS_TOTAL].avg; cryptodev_backend_set_throttle(backend, THROTTLE_BPS_TOTAL, value, errp); + if (*errp) { + return; + } if (bc->init) { bc->init(backend, errp); + if (*errp) { + return; + } } services = backend->conf.crypto_services; -- 2.41.0
