LSN in the future is not being treated as serious corruption

    XMLWordPrintable

Details

    Description

      InnoDB crash recovery is suppressing error messages about FIL_PAGE_LSN being in the future (recv_lsn_checks_on) and instead implementing a partly duplicated logic (recv_max_page_lsn). At least ever since the recovery was refactored in MDEV-29911, we’d better always enable these checks.

      Furthermore, InnoDB fails to treat a page as corrupted when it has a valid checksum but the FIL_PAGE_LSN is too large. This could lead to the database becoming increasingly more corrupted.
