---------------------------------

             Summary: SASL session expiration time will be overflowed when calculation
                 Key: KAFKA-14604
                 URL: https://issues.apache.org/jira/browse/KAFKA-14604
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 3.3.1
            Reporter: Luke Chen
            Assignee: Luke Chen


When sasl server of client set a large expiration time, the timeout value might be overflowed, and cause the session timeout immediately.

 

[Here|https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/security/authenticator/SaslServerAuthenticator.java#L694]'s the sasl server timeout's calculation

[Here|https://github.com/apache/kafka/blob/trunk/clients/src/main/java/org/apache/kafka/common/security/authenticator/SaslClientAuthenticator.java#L692]'s the sasl client timeout's calculation

 

something like this:
{code:java}
sessionExpirationTimeNanos = authenticationEndNanos + 1000 * 1000 * sessionLifetimeMs; {code}
So, if the configured or returned sessionLifetimeMs is a large number, after the calculation, it'll be a negative value, and cause the session timeout each check.
