alter the userspace sockaddr to convert the format between linux and BSD versions. That's the minimum 3 of copyin/copyout operations for one syscall. Also some syscall uses linux_sa_put() and linux_getsockaddr() when load sockaddr to userspace or from userspace accordingly. To avoid this chaos, especially converting sockaddr in the userspace, rewrite these 4 functions to convert sockaddr only in kernel and leave only 2 of this functions. Also in order to reduce duplication between MD parts of the Linuxulator put struct sockaddr conversion functions that are MI out into linux_common module.
