Re: [PATCH v2 3/5] memfd: improve userspace warnings for missing exec-related flags

* Andrew Morton:

OK, thanks, I'll revert this. Spamming everyone even harder isn't a good way to get developers to fix their stuff.

Is this really buggy userspace? Are future kernels going to require some of these flags?

That's going to break lots of applications which use memfd_create to enable run-time code generation on locked-down systems because it looked like a stable interface (“don't break userspace” and all that).

Thanks, Florian
