Subject: If perform_io() fails, kill the child before exiting so it doesn't
X-Git-Tag: SUDO_1_7_5~26
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d1f1065f1ab08a3a1d0e9ef4b76a7b58fd613db2;p=sudo

If perform_io() fails, kill the child before exiting so it doesn't
complain about connection reset.  We can get an I/O error if, for
example, and we get EIO reading from stdin.
