+Subject: Revert "sock: Reset dst when changing sk_mark via setsockopt"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit 4c5ce7ca90e00164f954d727215fc227addc467c which is
+commit 50254256f382c56bde87d970f3d0d02fdb76ec70 upstream.
+
+It breaks a number of runtime Android networking tests, so something is
+wrong with the backport, or something else also needed to be backported
+at the same time.  So I'm dropping this from the tree as regressions are
+not good.
