As I understand the getrandom() interface in modern Linux systems - it is documented to block until it is initialized and then never block again - is that an incorrect understanding of that interface?
More like incomplete. We use it with *GRND_NONBLOCK parameter to make sure it never blocks.*
Additionally, it would be good to ensure that any system running OpenBSC has some source of entropy beyond interrupts and timing - is that already the case?
Out of curiosity - is there a way to check for this programmatically?
Is there a system wide entropy depletion monitor in place?
Not that I know of. Is it some sort of a program or some kernel sysctl knob?
