From 2ea9cbefb8e0923f2f58e7e8022f3e134977a87a Mon Sep 17 00:00:00 2001 From: Scott Murray Date: Mon, 25 Jul 2022 14:23:13 -0400 Subject: Add SELinux feature Add agl-selinux feature to enable SELinux support. Notes: - SELinux is in permissive mode by default for now, and using the targeted policy by default. - The linux-yocto specific bbappend in meta-selinux is masked out in favor of adding a more universal kernel configuration fragment with AGL's own scheme. - SELinux specific recipes and bbappends are added via a meta-selinux dynamic-layers addition in meta-agl-core to keep using meta-selinux optional. This will avoid issues with the Yocto autobuilder testing of meta-agl-core. - To avoid the effectively hard-coded autorelabel on first boot, a bbappend is added to the selinux-autorelabel recipe to remove the flag creation. In the off chance that a build happens on a filesystem without xattr support, the logic in the selinux-image bbclass will still touch the /.autorelabel flag and trigger relabeling. - A systemd unit and script are added with a new systemd-selinux-relabel recipe to handle relabeling of some systemd generated files that do not get handled during root filesystem construction. Some of these can be addressed by some upstream tweaks, but /etc/machine-id will always need special handling unless there is a shift to using read-only or stateless root by default. With this workaround we still avoid doing a full relabel and reboot on first boot, which helps simplify CI.
