[PATCH] default-route: skip addition when the route already exists
(In reply to Beniamino Galvani from comment #3) > Created attachment 1307398 [details] > [PATCH] default-route: skip addition when the route already exists patch (and approach) locks good to me for nm-1-8 branch. But there are conflicts with master. ok, one thing: + _LOGt (AF_INET6, "update platform route: %s", + nm_platform_ip6_route_to_string (plat_rt, NULL, 0)); + _LOGt (AF_INET6, " with: %s", + nm_platform_ip6_route_to_string (&rt, NULL, 0)); maybe not log two lines? :) I know, it's only --with-more-logging, but our logging is already so verbose, please combine the lines.

[PATCH v2] default-route: skip addition when the route already exists
Patch rebased on master.
Applied to master: https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=bea6d05c1d3a92a14fd62267584e99b15f88687d and nm-1-8: https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?h=nm-1-8&id=bc9269ffcb8d44d6fb54c9c1d7c5fa5637d04bac CI test: https://github.com/NetworkManager/NetworkManager-ci/pull/14 Automated long time ago and running since then.
