From 4298d0b5128326621c8f537107c4c8b459490721 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Tue, 25 Feb 2014 20:37:03 +0100 Subject: core: add new RestrictAddressFamilies= switch This new unit settings allows restricting which address families are available to processes. This is an effective way to minimize the attack surface of services, by turning off entire network stacks for them. This is based on seccomp, and does not work on x86-32, since seccomp cannot filter socketcall() syscalls on that platform. --- src/shared/af-list.h | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 src/shared/af-list.h (limited to 'src/shared/af-list.h') diff --git a/src/shared/af-list.h b/src/shared/af-list.h new file mode 100644 index 0000000000..e346ab87f5 --- /dev/null +++ b/src/shared/af-list.h @@ -0,0 +1,27 @@ +/*-*- Mode: C; c-basic-offset: 8; indent-tabs-mode: nil -*-*/ + +#pragma once + +/*** + This file is part of systemd. + + Copyright 2014 Lennart Poettering + + systemd is free software; you can redistribute it and/or modify it + under the terms of the GNU Lesser General Public License as published by + the Free Software Foundation; either version 2.1 of the License, or + (at your option) any later version. + + systemd is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
