------------------------------------
Summary: Prefix ACLs may shadow other prefix ACLs
Key: KAFKA-14265
URL: https://issues.apache.org/jira/browse/KAFKA-14265
Project: Kafka
Issue Type: Bug
Reporter: Colin McCabe
Assignee: Colin McCabe
Prefix ACLs may shadow other prefix ACLs. Consider the case where we have
prefix ACLs for foobar, fooa, and f. If we were matching a resource named
"foobar", we'd start scanning at the foobar ACL, hit the fooa ACL, and stop --
missing the f ACL.
To fix this, we should re-scan for ACLs at the first divergence point (in this
case, f) whenever we hit a mismatch of this kind.
