I know nothing about DM, but the issue happens when doing a ioctl DM_TABLE_STATUS with params:
What do you mean by params? Status should not need any special params on input. Anyway, dm-verity in 6.19 now reports also number of error-corrected blocks in status line. If FEC is not used, it contains "-", for example # dmsetup status test 0 417792 verity V -
1 /dev/loop0 /dev/loop0 4096 4096 9 9 sha256 48048ef2c63d1c69a817508db0d3ff387ce33b10ec8fd0972bd29268836014a0 46c92f189b2036f93ec5805fb956adc134f8c17513bb51502f5cf92cf64fefe7 And after calling it params was expected to be empty (\0), and now it is "V -".
Could you please be more specific what command/ioctl you call here and post exact steps to reproduce different behavior here? The string above is table (dmsetup table), not status (dmsetup status). Isn't you code just confused by a new parameter in status line? Milan
