            Bug ID: 3487
           Summary: "getentropy failed" after upgrade from 9.0
           Product: Portable OpenSSH
           Version: 9.1p1
          Hardware: ARM
                OS: Linux
            Status: NEW
          Severity: critical
          Priority: P5
         Component: sshd
          Assignee: unassigned-bugs at mindrot.org
          Reporter: mindrot.org at felixvandyck.be

I have upgraded openssh from 9.0 to 9.1. After rebooting the system I
found that I was no longer able to connect to the SSH server
("connection refused" and "status 255").

I have checked systemd logs and found the following relevant items:

```
Oct 21 02:41:19 orbb sshd[255]: getentropy failed
Oct 21 02:41:19 orbb systemd[1]: sshd.service: Main process exited,
code=exited, status=255/EXCEPTION
Oct 21 02:41:19 orbb systemd[1]: sshd.service: Failed with result
'exit-code'.
```

When I ran `sshd -t` it also returned `getentropy failed`.

I inspected the upgraded packages and downgraded
openssh-9.1p1-1-armv7h.pkg.tar.xz back to
openssh-9.0p1-1-armv7h.pkg.tar.xz. I have restarted the service and was
able to connect via SSH again.

System:
Linux orbb 3.10.107-5-ARCH #1 SMP PREEMPT Fri Mar 26 23:32:03 UTC 2021
armv7l GNU/Linux


Kind regards
