Currently Nat464Xlat reads the clat IPv4 address and updates the clat LinkProperties when the interface is created. This causes a race condition: because clatd only sets the IPv4 address after creating the interface, it's possible that Nat464Xlat will read the address before clatd has set it, causing the framework to think that the clat IPv4 address is 0.0.0.0/32. This seems to be happening more frequently now, perhaps because clatd takes a bit longer to configure the IPv4 address now that it needs to check that the address is free before using it. Fix this by making Nat464Xlat listen for the interface coming up instead of listening for the interface being added. Bug: 12111730 Change-Id: Ic1c59b5b6dbb851b7431d1b06885f67803373bb9
