As far as I understand everything should work, because in 817efd3cad74 ("Bluetooth: hci_sock: Forward credentials to monit= or") we have a call to scm_recv(sock, msg, &scm, flags). And scm_recv does not use scm_pidfd_recv (and pidfd_prepare). Please tell me if something is not working and which tree I should take to reproduce it. I'm ready to dive into it. Kind regards, Alex
