--- Comment #8 from Hans Leidekker hans@meelstraat.net --- (In reply to Ruslan Kabatsayev from comment #7) 98741.147:0060:trace:ntdll:NtQuerySystemInformation (0x00000017,0x7e8ecd20,0x000000c0,(nil)) 98741.147:0060:fixme:ntdll:NtQuerySystemInformation getrandom returned -1 errno 38
So getrandom() returns ENOSYS. This suggests you're running glibc new enough to have a wrapper for the syscall on a kernel that doesn't implement this syscall. Can you describe your setup in more detail?
