Hm indeed it seems to have introduced 2 new flags and immediately warn if any process doesn't use them. Maybe it would make sense for some of the non-default values of vm.memfd_noexec, but it's too early to warn unconditionally everywhere, no?
Kees reply:
This is pretty standard for getting new options like this noticed by userspace -- there is no regression in behavior. It's just a reminder to fix userspace code.
Nothing to worry about here, the warning is so that developers are notified of these messages and eventually update their software.
when i was checking logs i did tail -f /var/log/syslog this showed up at last .
memfd_create() without MFD_EXEC nor MFD_NOEXEC_SEAL, pid=779 'systemd'
i dont know if this cause any concern but just wanted to share about it.
