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 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) diff --git a/plugins/admin.c b/plugins/admin.c index 1fe2904d93d9..d89a77c8a123 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; @@ -151,6 +152,11 @@ static DBusMessage *set_service_allowlist(DBusConnection *conn, return btd_error_failed(msg, "service_allowlist_set failed"); } + g_dbus_emit_property_changed(dbus_conn, + adapter_get_path(policy_data->adapter), + ADMIN_POLICY_STATUS_INTERFACE, + "ServiceAllowList"); + return dbus_message_new_method_return(msg); } @@ -160,6 +166,43 @@ static const GDBusMethodTable admin_policy_adapter_methods[] = { { } }; +void append_service_uuid(void *data, void *user_data) +{ + bt_uuid_t *uuid = data; + DBusMessageIter *entry = user_data; + char uuid_str[MAX_LEN_UUID_STR]; + const char *uuid_str_ptr = uuid_str; + + if (!uuid) { + error("Unexpected NULL uuid data in service_allowlist"); + return; + } + + bt_uuid_to_string(uuid, uuid_str, MAX_LEN_UUID_STR); + dbus_message_iter_append_basic(entry, DBUS_TYPE_STRING, &uuid_str_ptr); +} + +static gboolean property_get_service_allowlist( + const GDBusPropertyTable *property, + DBusMessageIter *iter, void *user_data) +{ + struct btd_admin_policy *admin_policy = user_data; + DBusMessageIter entry; + + dbus_message_iter_open_container(iter, DBUS_TYPE_ARRAY, + DBUS_TYPE_STRING_AS_STRING, &entry); + queue_foreach(admin_policy->service_allowlist, append_service_uuid, + &entry); + dbus_message_iter_close_container(iter, &entry); + + return TRUE; +} + +static const GDBusPropertyTable admin_policy_adapter_properties[] = { + { "ServiceAllowList", "as", property_get_service_allowlist }, + { } +}; + static int admin_policy_adapter_probe(struct btd_adapter *adapter) { const char *adapter_path; @@ -189,6 +232,21 @@ static int admin_policy_adapter_probe(struct btd_adapter *adapter) btd_info(policy_data->adapter_id, "Admin Policy Set interface registered"); + + if (!g_dbus_register_interface(dbus_conn, adapter_path, + ADMIN_POLICY_STATUS_INTERFACE, + NULL, NULL, + admin_policy_adapter_properties, + policy_data, admin_policy_free)) { + btd_error(policy_data->adapter_id, + "Admin Policy Status interface init failed on path %s", + adapter_path); + return -EINVAL; + } + + btd_info(policy_data->adapter_id, + "Admin Policy Status interface registered"); + return 0; }
