Yonatan Linik 06ab1e63ec net: fix proc_fs init handling in af_packet and tls ... [ Upstream commit a268e0f2455c32653140775662b40c2b1f1b2efa ] proc_fs was used, in af_packet, without a surrounding #ifdef, although there is no hard dependency on proc_fs. That caused the initialization of the af_packet module to fail when CONFIG_PROC_FS=n. Specifically, proc_create_net() was used in af_packet.c, and when it fails, packet_net_init() returns -ENOMEM. It will always fail when the kernel is compiled without proc_fs, because, proc_create_net() for example always returns NULL. The calling order that starts in af_packet.c is as follows: packet_init() register_pernet_subsys() register_pernet_operations() __register_pernet_operations() ops_init() ops->init() (packet_net_ops.init=packet_net_init()) proc_create_net() It worked in the past because register_pernet_subsys()'s return value wasn't checked before this Commit 36096f2f4f ("packet: Fix error path in packet_init."). It always returned an error, but was not checked before, so everything was working even when CONFIG_PROC_FS=n. The fix here is simply to add the necessary #ifdef. This also fixes a similar error in tls_proc.c, that was found by Jakub Kicinski.
