From 3bee0460d74bad88eca6592e63ca926961b43b67 Mon Sep 17 00:00:00 2001 From: Yi Zhao Date: Fri, 6 Mar 2020 16:09:26 +0800 Subject: [PATCH] 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).
