and userspace. In userspace, this is accessed through #include <secure.h> In the kernel, this is access through #include <kern/secure.h> There is a unit test for this (hm1) that computes the hmac and compares it to the known value. The salted vesion tested offline. ----- Also, fixed usespace compile issue with not changing KERNEL_SECRET => SECRET.
