Release Notes for MariaDB Enterprise Server 10.6.5-2
MariaDB Enterprise Server 10.6.5-2 is a maintenance release of MariaDB Enterprise Server 10.6. This release includes a variety of fixes.
MariaDB Enterprise Server 10.6.5-2 was released on 2021-12-13.
Fixed Security Vulnerabilities
CVE (with cve.mitre.org link)
CVSS base score
Galera updated to 26.4.10.
Debian 11 support added.
The default value of
spider_use_pushdown_udfhas changed from
In previous releases, Enterprise Spider pushed UDFs and Stored Functions down to the Data Node by default, which could cause query results to be inconsistent.
Starting with this release, all UDFs and stored functions are evaluated on the Spider Node by default. If desired, pushdown of UDFs and Stored Functions can be explicitly enabled by setting
spider_use_pushdown_udf=1. Testing is recommended to confirm that query results are consistent.
The InnoDB Force Recovery procedure has changed to differentiate between rollback of DDL and DML operations. The changes are: (MDEV-25683)
The behavior of
innodb_force_recoveryis no longer identical when
innodb_force_recovery=3is set, InnoDB skips rollback of DML operations, but DDL operations will still be rolled back using the DDL log.
innodb_force_recovery=4is set, InnoDB skips rollback of both DML and DDL operations. This behavior is equivalent to setting
innodb_force_recovery=3in versions earlier than MariaDB Enterprise Server 10.6.5.
Can result in a hang or crash
Resolving aggregate functions that are used in a view can cause in a crash. (MDEV-24454)
InnoDB causes server crash when a table is converted from
InnoDB persistent statistics causes server to hang. (MDEV-15020)
On an InnoDB table, when the server crashes or is killed while a
DROP TABLEor table-rebuilding
ALTER TABLEoperation is being executed, InnoDB causes a server crash during crash recovery, which occurs after the server has restarted. (MENT-1368)
InnoDB sometimes causes server crash during
ALTER TABLE .. IMPORT TABLESPACEwhen the imported tablespace contains columns that have been instantly reordered or dropped. The MariaDB error log contains the following error message: (MDEV-18543)
Schema mismatch (Index field name newcol doesn't match tablespace metadata field name name for field position...
Can result in unexpected behavior
MariaDB Enterprise Cluster joiner node incorrectly uses
localhostfor TLS certificate verification and fails to join cluster when
encrypt=3are configured. (MDEV-26360)
Memory leak with row-based replication can lead to high memory usage on replica servers. (MDEV-26712)
When statement-based or mixed replication is used and a DML statement encounters an error in a transaction that creates or drops a temporary table, non-committed writes to transactional tables can be incorrectly replicated to replica servers. (MDEV-26833)
Password validation plugins (including
simple_password_check) cause a user's existing password hash to be removed from the server's in-memory privilege cache when the user tries to change their password to an invalid password. (MDEV-26650)
InnoDB's adaptive purging can decrease throughput by starving user threads after
The server in some cases shows decreasing performance with notes
InnoDB: Cannot close file...in the error log. This issue occurs only when
open-files-limitis reached and a
log-checkpointis triggered. (MDEV-25215)
Replica server does not invalidate query cache after replicating table updates. (MENT-1360)
MariaDB Enterprise Cluster, powered by Galera, shows inconsistent values for
With MariaDB Enterprise Cluster, a replica server replicating from a MariaDB Enterprise Cluster node incorrectly uses the primary server's
wsrep_gtid_domain_idvalues to generate GTIDs for local transactions. (MDEV-26250)
When a new MariaDB Enterprise Cluster node is bootstrapped with
wsrep_gtid_mode=ONset, the node's configured
wsrep_gtid_domain_idvalues are overridden by the values present in the node's binary logs. (MDEV-26223)
