selinux: restrict kernel module loading
Utilize existing kernel_read_file hook on kernel module load. Add module_load permission to the system class. Enforces restrictions on kernel module origin when calling the finit_module syscall. The hook checks that source type has permission module_load for the target type. Example for finit_module: allow foo bar_file:system module_load; Similarly restrictions are enforced on kernel module loading when calling the init_module syscall. The hook checks that source type has permission module_load with itself as the target object because the kernel module is sourced from the calling process. Example for init_module: allow foo foo:system module_load; Signed-off-by: Jeff Vander Stoep <jeffv@google.com> [PM: fixed return value of selinux_kernel_read_file()] Signed-off-by: Paul Moore <paul@paul-moore.com>
