The getrandom(2) system call is a superset of getentropy(2). When we
add the support for this into glibc, it won't be terribly difficult
nor annoying to drop the following in alongside the standard support
needed for any new system call:
int getentropy(void *buf, size_t buflen)
{
int ret;
ret = getentropy(buf, buflen, 0);
return (ret > 0) ? 0 : ret;
}
The reason for the additional flags is that I'm trying to solve more
problems than just getentropy()'s raison d'etre. The discussion of
this is in the commit description; let me know if there bits that I
could make clearer.
This could still return predictable bytes during early boot, though,
right?
