> With TLSv1.3 and GCM-based cipher (the default), P2P Messaging Fails When
> Encrypted Data Limit is Reached
> ---------------------------------------------------------------------------------------------------------

> Key: GEODE-10122
> URL: https://issues.apache.org/jira/browse/GEODE-10122
> Project: Geode
> Issue Type: Bug
> Affects Versions: 1.13.7, 1.14.3, 1.15.0, 1.16.0
> Reporter: Bill Burcham
> Assignee: Bill Burcham
> Priority: Major
> Attachments: patch-P2PMessagingConcurrencyDUnitTest.txt

> TLSv1.3 introduced [1] the ability to set per-algorithm limits on symmetric
> key usage lifetimes. Once a certain number of bytes have been encrypted, a
> KeyUpdate post-handshake message is sent.
> With default settings, on Liberica JDK 11, Geode's P2P framework will
> negotiate TLSv1.3 with the TLS_AES_256_GCM_SHA384 cipher suite. Geode P2P
> messaging will eventually fail, with a "Tag mismatch!" IOException in shared
> ordered receivers, after a session has been in heavy use for days.
> We have not see this failure on TLSv1.2.
> The implementation of TLSv1.3 in the Java runtime provides a security
> property [2] to configure the encrypted data limit. The attached patch to
> P2PMessagingConcurrencyDUnitTest configures the limit large enough that the
> test makes it through the (P2P) TLS handshake but small enough so that the
> "Tag mismatch!" exception is encountered less than a minute later.
> The bug is caused by Geode’s NioSslEngine class’ ignorance of the
> “rehandshaking” phase of the TLS protocol [3]:
> Creation - ready to be configured.
> Initial handshaking - perform authentication and negotiate communication
> parameters.
> Application data - ready for application exchange.
> *Rehandshaking* - renegotiate communications parameters/authentication;
> handshaking data may be mixed with application data.
> Closure - ready to shut down connection.
> Geode's tcp.Connection and NioSslEngine classes (particularly wrap() and
> unwrap()), as they are currently implemented, fail to fully attend to the
> handshake status from javax.net.ssl.SSLEngine. As a result these Geode
> classes fail to respond to the KeyUpdate message, resulting in the "Tag
> mismatch!" IOException.
> When that exception is encountered, the Connection is destroyed and a new one
> created in its place. But users of the old Connection, waiting for
> acknowledgements, will never receive them. This can result in cluster-wide
> hangs.
