I can see that, because half of the qcow2 tests that contain the string
“secret” break:

Failures: 087 134 158 178 188 198 206
Failed 7 of 13 tests

Also, 210 when run with -luks.

Some are just due to different test outputs (because you change
_filter_img_create to filter some encrypt.* parameters), but some of
them are due to aborts.  All of them look like different kinds of heap
corruptions.


I can fully understand not running all iotests (because only the
maintainers do that before pull requests), but just running the iotests
that immediately concern a series seems prudent to me (unless the series
is trivial).

(Just “(cd tests/qemu-iotests && grep -l secret ???)” tells you which
tests to run that may concern themselves with qcow2 encryption, for
example.)


So I suppose I’ll stop reviewing the series in detail and just give a
more cursory glance from now on.
