The interface will provide read-only properties to indicate the current settings of admin policies. We separate this from AdminPolicySet so that normal clients can check current policy settings while only a few clients can change policies. This patch also adds readonly property ServiceAllowlist to AdminPolicyStatus1, which indicates the current setting of service allowlist. Reviewed-by: Miao-chen Chou --- The following test steps were performed: 1. Set ServiceAllowList to ["1124","180A","180F","1812"] 2. Verify ServiceAllowList is ["1124","180A","180F","1812"] in UUID-128 form 3. Set ServiceAllowList to [] 4. Verify ServiceAllowList is [] (no changes since v1) plugins/admin.c | 58 ++++++++++++++++++++++++++++++++++++++++++ plugins/admin_policy.c | 58 ++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 116 insertions(+) diff --git a/plugins/admin.c b/plugins/admin.c index 1fe2904d9..d89a77c8a 100644 --- a/plugins/admin.c +++ b/plugins/admin.c @@ -27,6 +27,7 @@ #include "src/shared/queue.h" #define ADMIN_POLICY_SET_INTERFACE "org.bluez.AdminPolicySet1" +#define ADMIN_POLICY_STATUS_INTERFACE "org.bluez.AdminPolicyStatus1" static DBusConnection *dbus_conn;
