/*
* Test Name: sendto02
*
* Description:
* When sctp protocol is selected in socket(2) and buffer is invalid,
* sendto(2) should fail and set errno to EFAULT, but it sets errno
* to ENOMEM.
*
* This is a regression test and has been fixed by kernel commit:
* 6e51fe7572590d8d86e93b547fab6693d305fd0d (sctp: fix -ENOMEM result
* with invalid user space pointer in sendto() syscall)
