+Subject: [PATCH] net: Fix issue with DNS not being updated
+
+When dns requests are made, go's native DNS resolver only reads
+/etc/resolv.conf if the previous request is older than 5 seconds.
+
+On first network call, an initialization code runs that is
+supposed to initialize DNS data and set lastChecked time. There is a bug
+in this code that causes /etc/resolv.conf to not be read during
+initialization and the DNS data from program startup ends up being used
+until the next 5 seconds. This means that if /etc/resolv.conf changed
+between program startup and the first network call, old DNS data is
+still used until the next 5 seconds.
+
+This causes "docker pull" to fail the first time if docker daemon is
+started before networking is up.
+
+Upstream commit d52883f443e1d564b0300acdd382af1769bf0477 made lot of
+improvements to DNS resolver to fix some issues which also fixes this
+issue.
+This patch picks the relevant changes from it to fix this particular
+issue.
+
+Upstream-Status: Backport [https://github.com/golang/go/commit/d52883f443e1d564b0300acdd382af1769bf0477]
