Brad Fitzpatrick fee74e7ea7 net/interfaces, wgengine/monitor: fix false positives link changes ... interfaces.State.String tries to print a concise summary of the network state, removing any interfaces that don't have any or any interesting IP addresses. On macOS and iOS, for instance, there are a ton of misc things. But the link monitor based its are-there-changes decision on interfaces.State.Equal, which just used reflect.DeepEqual, including comparing all the boring interfaces. On macOS, when turning wifi on or off, there are a ton of misc boring interface changes, resulting in hitting an earlier check I'd added on suspicion this was happening: [unexpected] network state changed, but stringification didn't This fixes that by instead adding a new interfaces.State.RemoveUninterestingInterfacesAndAddresses method that does, uh, that. Then use that in the monitor. So then when Equal is used later, it's DeepEqualing the already-cleaned version with only interesting interfaces. This makes cmd/tailscaled debug --monitor much less noisy. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>		4 years ago
