 Title: #263: KCM: include missing header file
Action: opened

PR body:
"""
man 2 readv says that the header file "sys/uio.h" must be included
for the functions readv/writev

Previously, "sys/uio.h" was included in "sys/socket.h" in glibc.
It worked just by a change. But it will be changed in glibc-2.26.
