The parameter innodb_log_checksums that was introduced in MariaDB 10.2.2 via MySQL 5.7.9 does not make much sense. The original motivation of introducing this parameter (initially called innodb_log_checksum_algorithm ) was that the InnoDB redo log used the slow and insecure innodb algorithm. With hardware or SIMD assisted CRC-32C computation being available, there should be no reason to allow checksums to be disabled on the redo log.
The parameter innodb_encrypt_log already implies innodb_log_checksums=ON .
Let us deprecate the parameter innodb_log_checksums and always compute redo log checksums, even if innodb_log_checksums=OFF is specified.

An upgrade from MariaDB 10.2.2 or later will only be possible after using the default value innodb_log_checksums=ON. If the non-default value innodb_log_checksums=OFF was in effect when the server was shut down, a log block checksum mismatch will be reported and the upgraded server will fail to start up.
