Presently we support xperms rules in source policy and in CIL modules. The binary policy module format however was never extended for xperms. This limitation inhibits use of xperms in refpolicy-based policy modules (including the selinux-testsuite policy). Update libsepol to support linking, reading, and writing a new binary policy module version that supports xperms rules. Update dismod to display xperms rules in binary policy modules. Also, to support use of a non-base binary policy module with a newer version on a system using a base policy module with an older version, automatically upgrade the version during module linking. This facilitates usage of newer features in non-base modules without requiring rebuilding the base module. Tests: 1. Add an allowxperms rule to the selinux-testsuite policy and confirm that it is properly written to the binary policy module (displayed by dismod), converted to CIL (the latter was already supported), and included in the kernel policy (via dispol and kernel test). 2. Use semodule_link and semodule_expand to manually link and expand all of the .pp files via libsepol, and confirm that the allowxperms rule is correctly propagated to the kernel policy. This test is required to exercise the legacy link/expand code path for binary modules that predated CIL. Signed-off-by: Stephen Smalley <sds@tycho.nsa.gov> |
