Hello,

applying these patches on top of Linux 6.12 causes seccomp to return
different error (ENNOSYS instead of EPERM) causing some seccomp tests to
fail.

A minimal reporoducer is

podman run --rm --security-opt seccomp=<(echo '{"defaultAction":"SCMP_ACT_ALLOW","syscalls":[{"names":["mkdir"],"action":"SCMP_ACT_ERRNO"}]}') docker.io/library/alpine mkdir /tmp/test

This should produce 'Operation not permitted' but produces
'Function not implemented'.

Can you have a look?

Thanks

Michal
