On an upgrade from an older-format ib_logfile* (MySQL 5.7 uses a similar format as MariaDB 10.2, 10.3, 10.4) it should be possible to relax the assertion with another condition. It should be possible to cover this scenario by extending the test innodb.log_corruption.
Thanks for fixing the debug specific issue. Please go ahead.
We might want to eliminate the assert for checking LSN altogether. I checked the reasoning but It doesn't seem to be good validating against some constant value. Also, checking for LSN in buf_page_get_gen looks a bit misplaced.
In
MDEV-34426, this assertion expression was relaxed so that on InnoDB bootstrap, we could write up to 120,000 bytes of log. I may have to think of a different solution while retaining a debug check.
