Description Kurt Seifried 2016-03-09 15:09:56 EST
Wesley Hearn of Red Hat reports:

Description of problem:
Users are able to access logs of a deleted namespace if recreated with the same name regardless if they were the previous owner.

Steps to Reproduce:
1. User A creates a namespace and populates logs
2. User A deletes namespace
3. User B creates a new namespace with the same name

Actual results:
User B can access logs from User A's namespace

Expected results:
User B should be restricted to logs generated from the pods he created in his new namespace.
