From 591d8ac37480f75aafe8895d6ee6a588886172ad Mon Sep 17 00:00:00 2001 From: Jan Radon Date: Fri, 15 May 2026 15:42:08 +0200 Subject: [PATCH] feat(rgw/kafka): add mTLS client certificate authentication for Kafka notifications Add support for mutual TLS (mTLS) client certificate authentication when publishing bucket notifications to Kafka brokers. RGW can now present a client certificate and private key to authenticate with brokers that require ssl.client.auth=required. Changes: - Add ssl-certificate-location, ssl-key-location, and ssl-key-password topic attributes for configuring client certificates - Validate that ssl_certificate and ssl_key are provided together - Include ssl_key_password in connection identity (hash/equality) - Add kafka-security.sh script for generating broker and client TLS certs - Add mTLS test (test_notification_kafka_security_ssl_mtls) using use_mtls=True flag on the existing SSL security path - Update RGW notifications documentation with mTLS parameters Fixes: http://tracker.ceph.com/issues/67427 Signed-off-by: Jan Radon --- doc/radosgw/notifications.rst | 25 +++ qa/tasks/kafka.py | 42 ++++- src/rgw/driver/rados/rgw_pubsub_push.cc | 5 +- src/rgw/rgw_kafka.cc | 73 +++++++-- src/rgw/rgw_kafka.h | 13 +- src/rgw/rgw_rest_pubsub.cc | 14 +- src/test/rgw/bucket_notification/README.rst | 25 ++- .../rgw/bucket_notification/kafka-security.sh | 27 ++++ src/test/rgw/bucket_notification/test_bn.py | 151 ++++++++++-------- 9 files changed, 285 insertions(+), 90 deletions(-) diff --git a/doc/radosgw/notifications.rst b/doc/radosgw/notifications.rst index 56b46b0087d7..de07940ef619 100644 --- a/doc/radosgw/notifications.rst +++ b/doc/radosgw/notifications.rst @@ -236,6 +236,9 @@ and must be between 1 and 256 characters long.
