This fix is part of the fix for issue 25099. In 25099, if an env has a empty name, then `docker run` will throw out an error: ``` ubuntu@ubuntu:~/docker$ docker run -e =A busybox true docker: Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"process_linux.go:295: setting oom score for ready process caused \\\"write /proc/83582/oom_score_adj: invalid argument\\\"\"\n". ``` This fix validates the Env in the container spec before it is sent to containerd/runc. Integration tests have been created to cover the changes. This fix is part of fix for 25099 (not complete yet, non-utf case may require a fix in `runc`). This fix is related to 25300.
