[PATCH] selinux: drop SECURITY_SELINUX_POLICYDB_VERSION_MAX

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: William Roberts <william.c.roberts@xxxxxxxxx>

Remove the SECURITY_SELINUX_POLICYDB_VERSION_MAX Kconfig option

Per: https://github.com/SELinuxProject/selinux/wiki/Kernel-Todo

This was only needed on Fedora 3 and 4 and just causes issues now,
so drop it.

The MAX and MIN should just be whatever the kernel can support.

-	  This option enables the maximum policy format version supported
-	  by SELinux to be set to a particular value.  This value is reported
-	  to userspace via /selinux/policyvers and used at policy load time.
-	  It can be adjusted downward to support legacy userland (init) that
-	  does not correctly handle kernels that support newer policy versions.

-	  Examples:
-	  For the Fedora Core 3 or 4 Linux distributions, enable this option
-	  and set the value via the next option. For Fedora Core 5 and later,
-	  do not enable this option.

-
-	  Examples:
-	  For Fedora Core 3, use 18.
-	  For Fedora Core 4, use 19.
-
-	  If you are unsure how to answer this question, look for the
-	  policy format version supported by your policy toolchain, by
-	  running 'checkpolicy -V'. Or look at what policy you have
-	  installed under /etc/selinux/$SELINUXTYPE/policy, where
-	  SELINUXTYPE is defined in your /etc/selinux/config.
