busybox: sysctl: ignore EIO of stable_secret below /proc/sys/net/ipv6/conf
Avoid confusing messages caused by EIO on reading /proc/sys/net/ipv6/conf/*/stable_secret if those are not set yet. Make it behave the same as procps(>=3.3.13). Fixes: $ sysctl -a | grep ipv6.conf | grep stable_secret sysctl: error reading key 'net.ipv6.conf.all.stable_secret': Input/output error sysctl: error reading key 'net.ipv6.conf.default.stable_secret': Input/output error sysctl: error reading key 'net.ipv6.conf.eth0.stable_secret': Input/output error sysctl: error reading key 'net.ipv6.conf.lo.stable_secret': Input/output error (From OE-Core rev: ff074f495dd4bb637618f790dd30e51e542cd30a) Signed-off-by: Yi Zhao <yi.zhao@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
