shield Security update for rabbitmq-server
SUSE-SLES-16.0-171

This update for rabbitmq-server fixes the following issues: Changes in rabbitmq-server: Update to 4.1.5: * Highlights - Khepri, an alternative schema data store developed to replace Mnesia, has matured and is now fully supported (it previously was an experimental feature) - AMQP 1.0 is now a core protocol that is always enabled. Its plugin is now a no-op that only exists to simplify upgrades. - The AMQP 1.0 implementation is now significantly more efficient: its peak throughput is more than double than that of 3.13.x on some workloads - Efficient sub-linear quorum queue recovery on node startup using checkpoints - Quorum queues now support priorities (but not exactly the same way as classic queues) - AMQP 1.0 clients now can manage topologies similarly to how AMQP 0-9-1 clients do it - The AMQP 1.0 convention (address format) used for interacting with with AMQP 0-9-1 entities is now easier to reason about - Mirroring (replication) of classic queues was removed after several years of deprecation. For replicated messaging data types, use quorum queues and/or streams. Non-replicated classic queues remain and their development continues - Classic queue storage efficiency improvements, in particular recovery time and storage of multi-MiB messages - Nodes with multiple enabled plugins and little on disk data to recover now start up to 20-30% faster - New exchange type: Local Random Exchange - Quorum queue log reads are now offloaded to channels (sessions, connections). - Initial Support for AMQP 1.0 Filter Expressions - Feature Flags Quality of Life Improvements - rabbitmqadmin v2 * Breaking Changes - Before a client connection can negotiate a maximum frame size (frame_max), it must authenticate successfully. Before the authenticated phase, a special lower frame_max value is used. - With this release, the value was increased from the original 4096 bytes to 8192 to accommodate larger JWT tokens. - amqplib is a popular client library that has been using a low frame_max default of 4096. Its users must upgrade to a compatible version (starting with 0.10.7) or explicitly use a higher frame_max. amqplib versions older than 0.10.7 will not be able to connect to RabbitMQ 4.1.0 and later versions due to the initial AMQP 0-9-1 maximum frame size increase covered above. - The default MQTT Maximum Packet Size changed from 256 MiB to 16 MiB. - The following rabbitmq.conf settings are unsupported: - cluster_formation.etcd.ssl_options.fail_if_no_peer_cert - cluster_formation.etcd.ssl_options.dh - cluster_formation.etcd.ssl_options.dhfile - Classic Queues is Now a Non-Replicated Queue Type - Quorum Queues Now Have a Default Redelivery Limit - Up to RabbitMQ 3.13, when an AMQP 0.9.1 client (re-)published a message to RabbitMQ, RabbitMQ interpreted the - AMQP 0.9.1 x-death header in the published message's basic_message.content.properties.headers field. - RabbitMQ 4.x will not interpret this x-death header anymore when clients (re-)publish a message. - CQv1 Storage Implementation was Removed - Settings cluster_formation.randomized_startup_delay_range.* were Removed - Several Disk I/O-Related Metrics were Removed - Default Maximum Message Size Reduced to 16 MiB - RabbitMQ 3.13 rabbitmq.conf setting rabbitmq_amqp1_0.default_vhost is unsupported in RabbitMQ 4.0. - RabbitMQ 3.13 rabbitmq.conf settings mqtt.default_user, mqtt.default_password, and amqp1_0.default_user are unsupported in RabbitMQ 4.0. - Starting with Erlang 26, client side TLS peer certificate chain verification settings are enabled by default in most contexts: from federation links to shovels to TLS-enabled LDAP client connections. - RabbitMQ Shovels will be able connect to a RabbitMQ 4.0 node via AMQP 1.0 only when the Shovel runs on a RabbitMQ node >= 3.13.7. * See https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.0.1 * and https://github.com/rabbitmq/rabbitmq-server/releases/tag/v4.1.0 for more info - Restore SLES logrotate file, (bsc#1246091)
