Change RAND_bytes return code in one error case #38

ctz · 2014-01-16T22:39:24Z

RAND_bytes now returns 0 on all errors. Previously, -1 would
be returned if the underlying RAND_METHOD didn't support the
'bytes' callback.

randtest now tests the error behaviour.
Documentation updated.
RAND_pseudo_bytes is unchanged, but its behaviour is also
described accurately in the documentation.

Please see the extended analysis on this blog post.

ping @mattcaswell

Looks ok, but needs updating because this was pre-reformat. Also the doc page has changed a bit since this PR was written because RAND_pseudo_bytes was deprecated.

Ping @richsalz see internal MR2732

richsalz · 2016-05-05T19:27:04Z

Suggest not waiting for me right now

mattcaswell · 2016-05-05T19:28:37Z

Ok. Ping anyone from the team then :-)

mattcaswell · 2016-05-18T09:42:09Z

The team view is that this will be revisited post-1.1.0

kroeckx · 2017-01-07T20:34:11Z

@ctz: Can you update this, and sign a CLA?

levitte · 2017-01-24T13:44:10Z

This PR changes the public API return codes. That makes it a 1.2.0 change.

richsalz · 2017-01-24T14:37:34Z

.... I'm not so sure of that. We've added error return codes before, I think. Needs more discussion.

levitte · 2017-01-24T17:45:22Z

I didn't say anything about error codes. RAND_bytes is changing returned value from -1 to 0. That's not an acceptable change before 1.2.0.

During my testing (*), I got below stack about leaked memory. - at database startup, Azure is registered as an object storage (--> registerAzureObjectStorage) - this calls into Azure, then into curl, and then into OpenSSL - curl asks OpenSSL for a bunch of random numbers (--> function 'ossl_random' in curl's OpenSSL wrapper) - OpenSSL initializes the random number generator and stores it in some random number generator context object (--> *RAND_get0_public) - this object is registered via pthread_key_create and pthread_setspecific registered in TLS - if registerAzureObjectStorage was the only place which initializes the RNG, we could argue that the leaked memory does not matter anyways as it is released after shutdown - RAND_get0_public also registers a free handler (rand_delete_thread_state) that runs in TLS, so the memory is released also if registration is called from arbitrary other threads. In sum: this is a false positive.
