+Subject: [PATCH 05/11] Handle noisy netlink sockets
+
+The POSIX implementation currently clears all network interfaces
+when netlink indicates that there has been a change. This causes
+the following problems:
+
+  1) Applications are informed that all of the services they are
+     tracking have been removed.
+  2) Increases network load because the client must re-query for
+     all records it is interested in.
+
+This changes netlink notification handling by:
+
+  1) Always comparing with the latest interface list returned
+     by the OS.
+  2) Confirming that the interface has been changed in a way
+     that we care about.

+Subject: [PATCH 06/11] Remove unneeded function
+
+Removes a function we no longer need by integrating it into the only
+function that calls it. This was originally separated so that we could
+only process network interfaces that netlink indicated had been changed,
+this has since been extended to test for all network intefaces.

+
+Tells the mDNS core if an interface is a loopback interface,
+similar to AddInterfaceToList() in the MacOS implementation.
+Also reorganizes SetupOneInterface() to use a const struct
+rather than growing its parameter list again.

+Subject: [PATCH 08/11] Mark deleted interfaces as being changed
+
+Netlink notification handling ignores messages for deleted links,
+RTM_DELLINK. It does handle RTM_GETLINK. According to libnl docu-
+mentation (http://www.infradead.org/~tgr/libnl/doc/route.html)
+RTM_DELLINK can be sent by the kernel, but RTM_GETLINK cannot.
+There was likely a mixup in the original implementation, so this
+change replaces handling for RTM_GETLINK with RTM_DELLINK.
+
+Testing and Verification Instructions:
+  1. Use ip-link to add and remove a VLAN interface and verify
+     that mDNSResponder handles the deleted link.

+From 19de26db69408f02241e232b39224589a0f630df Mon Sep 17 00:00:00 2001
+From: Nate Karstens <nate.karstens@garmin.com>
+Date: Thu, 10 Aug 2017 08:46:03 -0500
+Subject: [PATCH 11/11] Change a dynamic allocation to file-scope variable
+
+Changes a variable from being dynamically-allocated to being
+statically-allocated at the file scope. Addresses a Coverity
+issue where it appeared that the memory was being leaked.
+
+Upstream-Status: Submitted [dts@apple.com]
