Subject: [Buildroot] [PATCH v8 13/16] qemu x86 selinux: base br defconfig
Date: Fri, 10 Jul 2015 18:27:59 -0500 [thread overview]
Message-ID: <1436570882-56442-14-git-send-email-clayton.shotwell@rockwellcollins.com> (raw)

From: Clayton Shotwell <clshotwe@rockwellcollins.com>
This will build a base SELinux system that boots with SELinux
in permissive mode. Also adding documentation on how to use it.

Tested with QEMU 2.2.1
+
+-------------------------------------------------------------------
+
+Run the SElinux target emulation with:
+
+ qemu-system-i386 -M pc -kernel output/images/bzImage -drive file=output/images/rootfs.ext2,if=ide -append "root=/dev/sda rw console=ttyS0 selinux=1" -net nic,model=rtl8139 -net user -display none -serial stdio
+
+The emulation should reboot once the first time for relabeling and
+then provide a login prompt. The login is username root and password
+root because PAM requires a password in this secure configuration. To
+enable SELinux enforcing at boot, login and edit the
+/etc/selinux/config and set SELINUX to enforcing. Save and make sure
+to "sync" before restarting the emulation as the ext2 fs would
+otherwise corrupt when the emulation exits. After enforcing is
+default, the selinux= provided as part of the qemu "append" above can
+be used to turn enforcing on/off. This configuration would be tailored
+as part of a targets refpolicy customization.
