> While testing this, I found out why I had needed EINVAL earlier (and still do, for now): there is a bug in the Solaris implementation of getrandom(2). If flags are 0 and the buffer size > 1024, then it fails with EINVAL. That is only supposed to happen for a buffer that big if GNRD_RANDOM is set in flags but GNRD_NONBLOCK is not set. So until that bug is fixed, ... Ah! So it was useful to dig the EINVAL issue, it's a bug in the kernel :-) You wrote that the final version of Solaris 11.3 and 12 was not released yet. Can we expect a fix in the kernel before the final version?
