Before MDEV-12113 (MariaDB Server 10.1.25), on shutdown InnoDB would write the current LSN to the first page of each file of the system tablespace. This is incompatible with MariaDB's InnoDB table encryption, because encryption repurposed the field for an encryption key ID and checksum. buf_page_is_corrupted(): For the InnoDB system tablespace, skip FIL_PAGE_FILE_FLUSH_LSN when checking if a page is all zero, because the first page of each file in the system tablespace can contain nonzero bytes in the field. |
