# Eclass for installing SELinux policy, and optionally

# @BLURB: This eclass supports the deployment of the various SELinux modules in sec-policy
|
|
# @DESCRIPTION:
|
|
# The selinux-policy-2.eclass supports deployment of the various SELinux modules
|
|
# defined in the sec-policy category. It is responsible for extracting the
|
|
# specific bits necessary for single-module deployment (instead of full-blown
|
|
# policy rebuilds) and applying the necessary patches.
|
|
#
|
|
# Also, it supports for bundling patches to make the whole thing just a bit more
|
|
# manageable.
|
|
|
|
# @ECLASS-VARIABLE: MODS
|
|
# @DESCRIPTION:
|
|
# This variable contains the (upstream) module name for the SELinux module.
|
|
# This name is only the module name, not the category!
|
|
: ${MODS:="_illegal"}
|
|
|
|
# @ECLASS-VARIABLE: BASEPOL
|
|
# @DESCRIPTION:
|
|
# This variable contains the version string of the selinux-base-policy package
|
|
# that this module build depends on. It is used to patch with the appropriate
|
|
# patch bundle(s) that are part of selinux-base-policy.
|
|
: ${BASEPOL:=""}
|
|
|
|
# @ECLASS-VARIABLE: POLICY_PATCH
|
|
# @DESCRIPTION:
|
|
# This variable contains the additional patch(es) that need to be applied on top
|
|
# of the patchset already contained within the BASEPOL variable. The variable
|
|
# can be both a simple string (space-separated) or a bash array.
|
|
: ${POLICY_PATCH:=""}
|
|
|
|
# @ECLASS-VARIABLE: POLICY_TYPES
|
|
# @DESCRIPTION:
|
|
# This variable informs the eclass for which SELinux policies the module should
|
|
# be built. Currently, Gentoo supports targeted, strict, mcs and mls.
|
|
# This variable is the same POLICY_TYPES variable that we tell SELinux
|
|
# users to set in /etc/make.conf. Therefor, it is not the module that should
|
|
# override it, but the user.
