9.3 Using the SELinux Makefile
After
you modify a policy source file, you
must recompile the policy sources and load the translated binary
policy into the kernel. These and other common administrative
functions are performed by using the SELinux
Makefile, which typically resides in
/etc/security/selinux/src/policy. Chapter 4 introduced the SELinux
Makefile. Table 9-2 recaps
the six operations the Makefile provides.
Table 9-2. SELinux Makefile operations
Operation
Description
policy
Compile the policy sources, but do not create a new policy binary.
install
Compile the policy sources and createbut do not loada
new policy binary (default).
load
Compile, create, and load a new binary policy.
reload
Compile and create a new binary policy if the policy sources have
been recently modified; load the new binary policy.
clean
Delete temporary files created during policy compilation.
relabel
Relabel filesystems.To perform an operation using the Makefile, move
to the directory containing it. Then, issue the command:
make operationwhere operation
is one of the six
operations described in Table 9-2. For example, to
compile, create, and load a new binary policy, issue the command:
make loadTo reload the current policy, issue the command:
make reloadIf the policy sources have been modified since the binary policy file
was created, invoking make will also compile the
policy sources and create a new binary policy file.
