-Subject: [PATCH] util: fall back to reading /dev/urandom when getrandom()
- blocks
-
-With recent changes in the Linux kernel, the getrandom() system call may
-block for a long time after boot on machines that don't have enough
-entropy. It blocks the chronyd's initialization before it can detach
-from the terminal and may cause a chronyd service to fail to start due
-to a timeout.
-
-At least for now, enable the GRND_NONBLOCK flag to make the system call
-non-blocking and let the code fall back to reading /dev/urandom (which
-never blocks) if the system call failed with EAGAIN or any other error.
-
-This makes the start of chronyd non-deterministic with respect to files
-that it needs to open and possibly also makes it slightly easier to
-guess the transmit/receive timestamp in client requests until the
-urandom source is fully initialized.
