getrandom-nonblocking-v2.patch:
+ /* Alternative might be to return all-zeroes as a strong
+ * signal that these are not random data. */
I don't understand why you propose that in a comment of your change. I don't recall that this idea was proposed or discussed here.
IMHO it's a very bad idea to fill the buffer with zeros, the caller simply has no idea how to check the quality of the entropy. A buffer filled with zeros is "possible" even with high quality RNG, but it's really very very rare :-)
If you consider that a strong signal is required, you must raise an exception. But it looks like users don't care of the quality of the RNG, they request that Python "just works". |
