This characterization is unfortunate, since the getrandom() default
behavior is *not* the /dev/urandom behavior. In particular, the
getrandom() default behavior blocks until the kernel's internal pool has
been fully initialized, while /dev/urandom never blocks. This is one of
the main arguments for using getrandom() instead of /dev/urandom in the
I appreciate that the actual change landed in libgcrypt! This is a real
improvement for users of GNU/Linux systems. I just don't want people to
think that the change will cause them to possibly use an uninitialized
PRNG like /dev/urandom, because that is not the case with the change
that we made here.
