+Subject: [PATCH] dirmngr: Handle failures related to missing IPv6 gracefully
+
+Handle the two possible connect failures related to missing IPv6 support
+gracefully by marking the host dead and retrying with another one.
+If IPv6 is disabled via procfs, connect() will return EADDRNOTAVAIL.
+If IPv6 is not compiled into the kernel, it will return EAFNOSUPPORT.
+This makes it possible to use dual-stack hkp servers on hosts not having
+IPv6 without random connection failures.
