David Anderson	e00b814a24	Dockerfile: install iproute2 in the container image. Fixes #368. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	381b94d4d1	wgengine/router: include command output if `ip rule list` fails. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	e83d02ffd1	wgengine: don't double-close tundev on setup error. Part of #368. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	efc1feedc9	wgengine/router: include more information when iptables ops fail. The iptables package we use doesn't include command output, so we're left with guessing what went wrong most of the time. This will at least narrow things down to which operation failed.

Brad Fitzpatrick	529e2cb31a	ipn: add AllowVersionSkew bool to Notify & Message For "tailscale status" on macOS (from separately downloaded cmd/tailscale binary against App Store IPNExtension). (This isn't all of it, but I've had this sitting around uncommitted.)	5 years ago
Wendi Yu	fde384b359	Fix macOS build staticcheck used to fail on macOS (and presumably windows) due to a variable declared in a common package that was only used by the Linux build, which would prevent `redo pr` from passing on Mac. Moved variable declaration from the common file to the Linux-specific one to resolve the compiler complaint. Signed-off-by: Wendi Yu <wendi.yu@yahoo.ca>	5 years ago

Wendi Yu	0c69b4e00d	Implement rate limiting on log messages (#356 ) Implement rate limiting on log messages Addresses issue #317, where logs can get spammed with the same message nonstop. Created a rate limiting closure on logging functions, which limits the number of messages being logged per second based on format string. To keep memory usage as constant as possible, the previous cache purging at periodic time intervals has been replaced by an LRU that discards the oldest string when the capacity of the cache is reached.

David Anderson	b01db109f5	wgengine/router: use inet.af/netaddr, not wgcfg.CIDR. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	b8f01eed34	wgengine/router: remove wireguard-go config from settings. Instead, pass in only exactly the relevant configuration pieces that the OS network stack cares about. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	8861bb5a19	wgengine/router: alter API to support multiple addrs, and use on linux. FreeBSD and OpenBSD will error out with a complaint if we pass >1 address right now, but we don't yet so that's okay.	5 years ago
David Anderson	6802481bf5	wgengine/router: don't use gateway routes on linux.	5 years ago
David Anderson	78b1ed39ea	wgengine/router: add more documentation.	5 years ago

David Anderson	89af51b84d	wgengine: plumb locally advertised subnet routes. With this change, advertising subnet routes configures the firewall correctly. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	89198b1691	wgengine/router: rewrite netfilter and routing logic. New logic installs precise filters for subnet routes, plays nice with other users of netfilter, and lays the groundwork for fixing routing loops via policy routing.

Brad Fitzpatrick	44b07aa708	netcheck: STUN less aggressively to known distant servers If Australia's far away and not going to be used, it's still going to be far away a minute later. No need to send backup just-in-case-UDP-gets-lost STUN packets to the known far away destinations. Those are the ones most likely to trigger retries due to delay anyway (in random 50-250ms, currently). But we'll keep sending 1 packet to them, just in case our airplane landed. Likewise, be less aggressive with IPv6. The main point is just to see whether IPv6 works. No need to send up to 10 packets every round. Max two is enough (except for the first round). This does mean our STUN traffic graphs for IPv4-vs-IPv6 will change shape. Oh well. It was a weird eyeball metric for IPv6 connectivity anyway and we have better metrics. We can tweak this policy over time. It's factored out and has tests now.	5 years ago

Avery Pennarun	108237798d	controlclient and ipn tests: supply --advertise-tags and --advertise-routes. This helps validate the server's behaviour when these are present.	5 years ago

Avery Pennarun	9d1f48032a	cmd/tailscale: add --advertise-tags option. These will be used for dynamically changing the identity of a node, so its ACL rights can be different from your own. Note: Not all implemented yet on the server side, but we need this so we can request the tagged rights in the first place. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago

Avery Pennarun	65fbb9c303	wgengine/filter: support subnet mask rules, not just /32 IPs. This depends on improved support from the control server, to send the new subnet width (Bits) fields. If these are missing, we fall back to assuming their value is /32. Conversely, if the server sends Bits fields to an older client, it will interpret them as /32 addresses. Since the only rules we allow are "accept" rules, this will be narrower or equal to the intended rule, so older clients will simply reject hosts on the wider subnet (fail closed). With this change, the internal filter.Matches format has diverged from the wire format used by controlclient, so move the wire format into tailcfg and convert it to filter.Matches in controlclient.

Avery Pennarun	d6c34368e8	ipn/local: differentiate Shields Up from Uninitialized in logs. We were printing "Shields Up" when the netmap wasn't initialized yet, which while technically effectively true, turned out to be confusing when trying to debug things. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	64db026c8b	backoff: add a LogLongerThan configuration. Some programs use frequent short-duration backoffs even under non-error conditions. They can set this to avoid logging short backoffs when things are operating normally, but still get messages when longer backoffs kick in. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	ced9b4008a	ipn: clear the hostinfo.Services list when prefs.ShieldsUp==true. When shields are up, no services are available to connect to, so hide them all. This will also help them disappear from the UI menu on other nodes. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	d7429b9a8d	Add prefs.ShieldsUp and --shields-up option. This sets a default packet filter that blocks all incoming requests, giving end users more control over who can get into their machine, even if the admin hasn't set any central ACLs. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	85e675940d	wgengine/filter: allow ICMP response packets. Longer term, we should probably update the packet filter to be fully stateful, for both TCP and ICMP. That is, only ICMP packets related to a session we initiated should be allowed back in. But this is reasonably secure for now, since wireguard is already trimming most traffic. The current code would not protect against eg. Ping-of-Death style attacks from VPN nodes. Fixes tailscale/tailscale#290. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	dbc1f71e5d	ipn/message: fix some message encoding problems. - Reset() was not including a Version field, so was getting rejected; the Logout operation no longer happened when the client got disconnected. - Don't crash if we can't decode 0-byte messages, which I suspect might sometimes come through on EOF.
