-------------------------------------
Summary: Fix GcmTransportCipher to correctly handle multiple
messages per channel
Key: SPARK-56227
URL: https://issues.apache.org/jira/browse/SPARK-56227
Project: Spark
Issue Type: Bug
Components: Security
Affects Versions: 4.1.1, 3.5.8
Reporter: Akira Ajisaka
AES-GCM for RPC encryption was introduced by SPARK-47172, however, now the
feature doesn't correctly handle multiple messages per channel. In YARN
application, the auth handshake succeeds but all post-auth RPC messages are
dropped or corrupted, leaving the channel hung until YARN kills the container.
