Denton Gentry	54ba6194f7	interfaces: allow IPv6 ULA as a valid address. IPv6 Unique Local Addresses are sometimes used with Network Prefix Translation to reach the Internet. In that respect their use is similar to the private IPv4 address ranges 10/8, 172.16/12, and 192.168/16. Treat them as sufficient for AnyInterfaceUp(), but specifically exclude Tailscale's own IPv6 ULA prefix to avoid mistakenly trying to bootstrap Tailscale using Tailscale. This helps in supporting Google Cloud Run, where the addresses are 169.254.8.1/32 and fddf:3978:feb1:d745::c001/128 on eth1. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	4 years ago
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	7dc88e4c1e	net/interfaces: track more interface metadata in State We have it already but threw it away. But macOS/iOS code will be needing the interface index, so hang on to it. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	d5fd373f09	net/interfaces: skip IPv6 link-local interfaces like we do for IPv4 We strip them control-side anyway, and we already strip IPv4 link local, so there's no point uploading them. And iOS has a ton of them, which results in somewhat silly amount of traffic in the MapRequest. We'll be doing same-LAN-inter-tailscaled link-local traffic a different way, with same-LAN discovery.

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
Brad Fitzpatrick	829eb8363a	net/interfaces: sort returned addresses from LocalAddresses Also change the type to netaddr.IP while here, because it made sorting easier. Updates tailscale/corp#1397 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
David Anderson	f647e3daaf	ipn/ipnlocal: transform default routes into "all but LAN" routes. Fixes #1177. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Brad Fitzpatrick	20e66c5b92	net/interfaces: reconcile interface filtering with address printing in logs The interface.State logging tried to only log interfaces which had interesting IPs, but the what-is-interesting checks differed between the code that gathered the interface names to print and the printing of their addresses.	4 years ago

David Anderson	baa7937998	net/interfaces: return IPv6 addresses from LocalAddresses. In practice, we already provide IPv6 endpoint addresses via netcheck, and that address is likely to match a local address anyway (i.e. no NAT66). The comment at that piece of the code mentions needing to figure out a good priority ordering, but that only applies to non-active-discovery clients, who already don't do anything with IPv6 addresses.

Brad Fitzpatrick	6ee219a25d	ipn, wgengine, magicsock, tsdns: be quieter and less aggressive when offline If no interfaces are up, calm down and stop spamming so much. It was noticed as especially bad on Windows, but probably was bad everywhere. I just have the best network conditions testing on a Windows VM. Updates #604	4 years ago

Brad Fitzpatrick	8051ecff55	net/interfaces: add State.PAC field, populate it on Windows Not used for anything yet (except logging), but populate the current proxy autoconfig PAC URL in Interfaces.State. A future change will do things based on it.	4 years ago

Brad Fitzpatrick	5c6d8e3053	netcheck, tailcfg, interfaces, magicsock: survey UPnP, NAT-PMP, PCP Don't do anything with UPnP, NAT-PMP, PCP yet, but see how common they are in the wild. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	0245bbe97b	Make netcheck handle v6-only interfaces better, faster. Also: * add -verbose flag to cmd/tailscale netcheck * remove some API from the interfaces package * convert some of the interfaces package to netaddr.IP * don't even send IPv4 probes on machines with no IPv4 (or only v4 loopback) * and once three regions have replied, stop waiting for other probes at 2x the slowest duration.

Brad Fitzpatrick	5c1e443d34	wgengine/monitor: don't call LinkChange when interfaces look unchanged Basically, don't trust the OS-level link monitor to only tell you interesting things. Sanity check it. Also, move the interfaces package into the net directory now that we have it.	5 years ago
