chromeos sdk, ssh error: file descriptor passing not supported

Project Member Reported by kcwu@chromium.org, Oct 27 
Reproduce step:
 1. cros_sdk --delete
 2. cros_sdk ssh -o ControlPersist=1m -o ControlMaster=yes -o ControlPath=/tmp/control-socket -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o BatchMode=yes $DUT_IP true
This line should exit 0. For some version of chromeos, the ssh executable shipped with the SDK is broken and it shows
   mm_send_fd: file descriptor passing not supported
   mux_client_request_session: send fds failed
and exit 255.

This issue has ever happened in the past -- 10890.0.0 and 10891.0.0 is broken ( issue 865511 ).
Today, I encountered this issue again.

----
There is a workaround for this issue:
Run this command inside cros_sdk.
   sudo emerge net-misc/openssh
