Actually, I've had a look at the Linux and Windows documentation, and sir_name is NUL-terminated. I've also had a look at the kernel source, and it treats sir_name as NUL-terminated, so it should be safe.

Here's a new patch, with a couple new constants, documentation update and some - really basic - tests.
I guess Gregory is right, and we could push this as-is, and wait until some users is interested in improving the support and tests.
