History
Jessica Clarke a98fa52ec6 kldxref: Avoid buffer overflows in parse_pnp_list 
We convert a string like "W32:vendor/device" into "I:vendor;I:device",
where the output is longer than the input, but only allocate space equal
to the length of the input, leading to a buffer overflow.

Instead use open_memstream so we get a safe dynamically-grown buffer.
