Brad Fitzpatrick	7f174e84e6	net/interfaces: remove mutating methods, add EqualFiltered instead Now callers (wgengine/monitor) don't need to mutate the state to remove boring interfaces before calling State.Equal. Instead, the methods to remove boring interfaces from the State are removed, as is the reflect-using Equal method itself, and in their place is a new EqualFiltered method that takes a func predicate to match interfaces to compare. And then the FilterInteresting predicate is added for use with EqualFiltered to do the job that that wgengine/monitor previously wanted. Now wgengine/monitor can keep the full interface state around, including the "boring" interfaces, which we'll need for peerapi on macOS/iOS to bind to the interface index of the utunN device.

Brad Fitzpatrick	0994a9f7c4	wgengine{,/magicsock}: fix, improve "tailscale ping" to default routes and subnets e.g. $ tailscale ping 1.1.1.1 exit node found but not enabled $ tailscale ping 10.2.200.2 node "tsbfvlan2" found, but not using its 10.2.200.0/24 route $ sudo tailscale up --accept-routes $ tailscale ping 10.2.200.2 pong from tsbfvlan2 (100.124.196.94) via 10.2.200.34:41641 in 1ms $ tailscale ping mon.ts.tailscale.com pong from monitoring (100.88.178.64) via DERP(sfo) in 83ms pong from monitoring (100.88.178.64) via DERP(sfo) in 21ms pong from monitoring (100.88.178.64) via [2604:a880:4:d1::37:d001]:41641 in 22ms This necessarily moves code up from magicsock to wgengine, so we can look at the actual wireguard config.

Brad Fitzpatrick	387e83c8fe	wgengine/magicsock: fix Conn.Rebind race that let ErrClosed errors be read There was a logical race where Conn.Rebind could acquire the RebindingUDPConn mutex, close the connection, fail to rebind, release the mutex, and then because the mutex was no longer held, ReceiveIPv4 wouldn't retry reads that failed with net.ErrClosed, letting that error back to wireguard-go, which would then stop running that receive IP goroutine. Instead, keep the RebindingUDPConn mutex held for the entirety of the replacement in all cases. Updates tailscale/corp#1289 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
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
