Support dockerd and system restarts for ipvlan and macvlan networks #2415

arkodg · 2019-07-10T04:50:58Z

This commit carries forward the work done in
#2295
and fixes two things

Allows macvlan and ipvlan to be restored properly
after dockerd or the system is restarted
Makes sure the refcount for the configOnly network
is not incremented for the above case so this network
can be deleted after all the associated ConfigFrom networks
are deleted

+					return false, err
+				}
+				// if driver created the networks slave link, record it for future deletion
+				config.CreatedSlaveLink = true


I am hoping CreateSlaveLink will be already set to true vlanLinkExists returns True.
If not, can you pls move this line out of if condition.

ip mac vlan code I see there is else condition with debug log "vlan already exists" . should we add similar log here for consistent purpose ?

added the missing logs, also config.CreatedSlaveLink is already set to true, that is why we don't set it for the restart case

+				}
+				config.CreatedSlaveLink = true
+			} else {
+				logrus.Debugf("Dummy Link %s for Mac Vlan already exists", getDummyName(stringid.TruncateID(config.ID)))


should we have . config.CreatedSlaveLink = true in this else loop too? ( same as ipvlan code )? just to make sure "config.CreatedSlaveLink is set to True.
