I don't think __kernel_size_t is required anywhere in this patch, size_t
should be fine.

It would be cleaner to use static functions instead of calling syscall()
each time.

This assert fails because errno == EOPNOTSUPP.

There is no test that actually set an attribute. Would it be possible to
load a simple dummy policy to be able to test that with at least one LSM?
Ditto for reading attribute, there are only tests that check for errors
but not to get attribute contents (only names with basic_lsm_get_self_attr).

This only works if there is at least on LSM enabled. You should probably
list the three that use these syscalls in the config file (if they are
stackable).
Also, all the get and list tests fail if there is no LSM enabled.
