From 84e862614a39d6e1d5d2317472175ec79bbc769f Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Tue, 23 Jun 2015 12:03:10 +0200 Subject: [PATCH] sd-netlink: don't treat type_system->count==0 as invalid Empty type-systems are just fine. Avoid the nasty hack in union-type-systems that treat empty type-systems as invalid. Instead check for the actual types-array and make sure it's non-NULL (which is even true for empty type-systems, due to "empty_types" array). --- src/libsystemd/sd-netlink/netlink-types.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/libsystemd/sd-netlink/netlink-types.c b/src/libsystemd/sd-netlink/netlink-types.c index c4573b609..d22194ad7 100644 --- a/src/libsystemd/sd-netlink/netlink-types.c +++ b/src/libsystemd/sd-netlink/netlink-types.c @@ -598,7 +598,7 @@ int type_system_union_protocol_get_type_system(const NLTypeSystemUnion *type_sys return -EOPNOTSUPP; type_system = &type_system_union->type_systems[protocol]; - if (type_system->count == 0) + if (!type_system->types) return -EOPNOTSUPP; *ret = type_system; -- 2.30.2
