H A D | policy.c | c30a3c95 Mon Aug 31 13:28:05 CDT 2020 Johannes Berg <johannes.berg@intel.com> netlink: policy: correct validation type check
In the policy export for binary attributes I erroneously used a != NLA_VALIDATE_NONE comparison instead of checking for the two possible values, which meant that if a validation function pointer ended up aliasing the min/max as negatives, we'd hit a warning in nla_get_range_unsigned().
Fix this to correctly check for only the two types that should be handled here, i.e. range with or without warn-too-long.
