David Handermann updated NIFI-7468:
-----------------------------------
Status: Patch Available (was: In Progress)
> Improve internal handling of SSL channels
> -----------------------------------------
>
> Key: NIFI-7468
> URL: https://issues.apache.org/jira/browse/NIFI-7468
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework, Extensions
> Affects Versions: 1.11.4
> Reporter: Andy LoPresto
> Assignee: David Handermann
> Priority: Major
> Labels: security, ssl, tcp, tls, tlsv1.3, udp
> Time Spent: 40m
> Remaining Estimate: 0h
>
> While refactoring the TLS protocol version issue in NIFI-7407, I discovered
> that some processors make use of NiFi custom implementations of
> {{SSLSocketChannel}}, {{SSLCommsSession}}, and
> {{SSLSocketChannelInputStream}}. These implementations break on TLSv1.3.
> Further investigation is needed to determine why these custom implementations
> were provided originally, whether they are still required, and why they do
> not handle TLSv1.3 successfully.
> Diagnostic error:
> {code}
> Error reading from channel due to Tag mismatch!: javax.net.ssl.SSLException:
> Tag mismatch!
> {code}
