Thank you so much for quick reply.
I think you are absolutely right for Debian Stable.
And I don't think I was right even in Debian Testing
because I do not know what is done in the trinity test.
I think I understand why the conservative approach is needed.
I was merely curious about what makes the differences
between x32-specific security bugs and non-x32-specific ones.
I believe the x32 binary support is just an option not different from the other kernel options;
and any kernel option increases the threatening level in security.
But we do not turned off all the kernel options; even though we all know that bugs are everywhere.
I can totally agree with you if the reason why x32-option is turned off is
that it can't be built as a module, rarely used, or hard to test.
But if not, I just thought x32-specific feature can be tested in Sid or Testing like the other features
because those stages aim to find out bugs.
Anyhow I really appreciate that you inform me of the current situation and the progress.
If you have any hyperlink to knowledge base about trinity test, please let me know. ( I googled it for a while bug found nothing. )
Thank you.
