Subject: [RFC v4 01/18] landlock: Add Kconfig
Date: Wed, 26 Oct 2016 08:56:37 +0200 [thread overview]
Message-ID: <20161026065654.19166-2-mic@digikod.net> (raw)
In-Reply-To: <20161026065654.19166-1-mic@digikod.net>
Initial Landlock Kconfig needed to split the Landlock eBPF and seccomp
parts to ease the review.
Changes from v2:
* add seccomp filter or cgroups (with eBPF programs attached support)
dependencies

+ Landlock is a stacked LSM which allows any user to load a security
+ policy to restrict their processes (i.e. create a sandbox). The
+ policy is a list of stacked eBPF programs for some LSM hooks. Each
+ program can do some access comparison to check if an access request
+ is legitimate.
+
+ You need to enable seccomp filter and/or cgroups (with eBPF programs
+ attached support) to apply a security policy to either a process
+ hierarchy (e.g. application with built-in sandboxing) or a group of
+ processes (e.g. container sandboxing). It is recommended to enable
+ both seccomp filter and cgroups.
+
+ Further information about eBPF can be found in
+ Documentation/networking/filter.txt
+
+ If you are unsure how to answer this question, answer Y.
