seccomp profile: Default to ENOSYS instead of EPERM
Browse files Browse the repository at this point in the history
This allows application to detect whether the kernel supports
syscall or not. Previously, an error was unconditionally EPERM.
There are many issues about glibc failed with new syscalls in containerized
environments if their host run on old kernel.

More about motivation for ENOSYS over EPERM:
opencontainers/runc#2151
opencontainers/runc#2750

See about defaultErrnoRet introduction:
opencontainers/runtime-spec#1087

Previously, FreeIPA profile was vendored from
https://github.com/containers/podman/blob/main/vendor/github.com/containers/common/pkg/seccomp/seccomp.json

Now it is merged directly from
https://github.com/containers/common/blob/main/pkg/seccomp/seccomp.json

Fixes: https://pagure.io/freeipa/issue/9008
