This adds a check for org.bluez.mesh.Manager1 interface calls to validate that a message sender, i.e. thatt the sender is the original owner of the node object generated on Attach() method call. If the check fails, org.bluez.mesh.Error.NotAuthorized is returned. --- mesh/manager.c | 60 +++++++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 57 insertions(+), 3 deletions(-) diff --git a/mesh/manager.c b/mesh/manager.c index 633597659..b39ea6ed7 100644 --- a/mesh/manager.c +++ b/mesh/manager.c @@ -287,6 +287,10 @@ static struct l_dbus_message *import_node_call(struct l_dbus *dbus, uint8_t num_ele;
