Alexander Mikhalitsyn a9c49cc2f5 net: scm: introduce and use scm_recv_unix helper ... Recently, our friends from bluetooth subsystem reported [1] that after commit 5e2ff6704a ("scm: add SO_PASSPIDFD and SCM_PIDFD") scm_recv() helper become unusable in kernel modules (because it uses unexported pidfd_prepare() API). We were aware of this issue and workarounded it in a hard way by commit 97154bcf4d ("af_unix: Kconfig: make CONFIG_UNIX bool"). But recently a new functionality was added in the scope of commit 817efd3cad74 ("Bluetooth: hci_sock: Forward credentials to monitor") and after that bluetooth can't be compiled as a kernel module. After some discussion in [1] we decided to split scm_recv() into two helpers, one won't support SCM_PIDFD (used for unix sockets), and another one will be completely the same as it was before commit 5e2ff6704a ("scm: add SO_PASSPIDFD and SCM_PIDFD").
