The default value of checkreqprot + at boot was changed starting in Linux v4.4 to 0 (i.e. check the + actual protection), and Android and Linux distributions have been + explicitly writing a "0" to /sys/fs/selinux/checkreqprot during + initialization for some time. Support for setting checkreqprot to 1 + will be removed no sooner than June 2021, at which point the kernel + will always cease using checkreqprot internally and will always + check the actual protections being applied upon mmap/mprotect calls. + The checkreqprot selinuxfs node will remain for backward compatibility + but will discard writes of the "0" value and will reject writes of the + "1" value when this mechanism is removed. diff --git a/Documentation/ABI/obsolete/sysfs-selinux-disable b/Documentation/ABI/obsolete/sysfs-selinux-disable new file mode 100644 index 000000000..c340278e3 --- /dev/null +++ b/Documentation/ABI/obsolete/sysfs-selinux-disable @@ -0,0 +1,26 @@ +What: /sys/fs/selinux/disable +Date: April 2005 (predates git) +KernelVersion: 2.6.12-rc2 (predates git) +Contact: selinux@vger.kernel.org +Description: + + The selinuxfs "disable" node allows SELinux to be disabled at runtime + prior to a policy being loaded into the kernel. If disabled via this + mechanism, SELinux will remain disabled until the system is rebooted. + + The preferred method of disabling SELinux is via the "selinux=0" boot + parameter, but the selinuxfs "disable" node was created to make it + easier for systems with primitive bootloaders that did not allow for + easy modification of the kernel command line. Unfortunately, allowing + for SELinux to be disabled at runtime makes it difficult to secure the + kernel's LSM hooks using the "__ro_after_init" feature. + + Thankfully, the need for the SELinux runtime disable appears to be + gone, the default Kconfig configuration disables this selinuxfs node, + and only one of the major distributions, Fedora, supports disabling + SELinux at runtime. Fedora is in the process of removing the + selinuxfs "disable" node and once that is complete we will start the + slow process of removing this code from the kernel. + + More information on /sys/fs/selinux/disable can be found under the + CONFIG_SECURITY_SELINUX_DISABLE Kconfig option. |
