Subject: route-table: Close netlink notifier before closing nln.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f4dc8c5895ed6a95c7331910c4c54107d783cba5;p=openvswitch

route-table: Close netlink notifier before closing nln.

Commit 2ee6545f2bff7eb27e8c84965e3ff38dfa909bf6 "notifiers: Create
and destroy nln_notifiers." requires callers to explicitly create
and destroy netlink notifiers but route-table only did the creation
part.  This causes an assertion failure any time the netdev for a
vport is destroyed (for example ovs-dpctl show when there is a
tunnel port).

Bug #7464
