Patch Set 3:

Note: the current version does not implement direct reading from /dev/urandom as a fallback when getrandom() is missing. Instead insecure rand() used and error is reported to caller. The reasons are twofold: 1) it's much simpler 2) that matches the way RAND_bytes() is used throughout OpenBSC. I can add it in future revisions if necessary.

Also, there's no initialization for entropy pool: if there's insufficient entropy than we'll fail with error as described above. I'm not sure how can I initialize kernel's entropy pool programmatically (or if it's possible at all) - any ideas would be appreciated.
