2018-06-27	Call mm.CheckIORange() when copying in IOVecs.	Nicolas Lacasse
	CheckIORange is analagous to Linux's access_ok() method, which is checked when copying in IOVecs in both lib/iov_iter.c:import_single_range() and lib/iov_iter.c:import_iovec() => fs/read_write.c:rw_copy_check_uvector(). gVisor copies in IOVecs via Task.SingleIOSequence() and Task.CopyInIovecs(). We were checking the address range bounds, but not whether the address is valid. To conform with linux, we should also check that the address is valid. For usual preadv/pwritev syscalls, the effect of this change is not noticeable, since we find out that the address is invalid before the syscall completes. For vectorized async-IO operations, however, this change is necessary because Linux returns EFAULT when the operation is submitted, but before it executes. Thus, we must validate the iovecs when copying them in. PiperOrigin-RevId: 202370092 Change-Id: I8759a63ccf7e6b90d90d30f78ab8935a0fcf4936
