Hi Toke,
just a random thought:
+ getrandom(n->hmac_nonce, BABEL_HMAC_NONCE_LEN, 0);
I think we cannot rely on getrandom() being available on all systems. It probably needs wrapping in sysdep code.
Yeah, figured I would probably have to look into something like that. Any idea if there is an interface that *is* available across systems?
Hi
I would be surprised if there was portable syscall for that. There is getentropy() for OpenBSD and arc4rand() for FreeBSD. so all these could be wrapped in sysdep code to offer uniform interface for rest of BIRD.
Also note that even getrandom() is relatively recent. We probably should handle somehow the case that none of these is available.
Right, I'll look into a sysdep function + compatibility. -Toke
