From: Yu Watanabe Date: Fri, 22 Feb 2019 13:27:44 +0900 Subject: network: remove routing policy rule from foreign rule database when it is removed Previously, When the first link configures rules, it removes all saved rules, which were configured by networkd previously, in the foreign rule database, but the rules themselves are still in the database. Thus, when the second or later link configures rules, it errnously treats the rules already exist. This is the root of issue #11280. This removes rules from the foreign database when they are removed. Fixes #11280.
