Val	059051c58a	wgengine,net,ipn,disco: split up and define different types of MTU Prepare for path MTU discovery by splitting up the concept of DefaultMTU() into the concepts of the Tailscale TUN MTU, MTUs of underlying network interfaces, minimum "safe" TUN MTU, user configured TUN MTU, probed path MTU to a peer, and maximum probed MTU. Add a set of likely MTUs to probe. Updates #311 Signed-off-by: Val <valerie@tailscale.com>	1 year ago

James Tucker	a82a74f2cf	cmd/containerboot: avoid leaking bash scripts after test runs The test was sending SIGKILL to containerboot, which results in no signal propagation down to the bash script that is running as a child process, thus it leaks. Minor changes to the test daemon script, so that it cleans up the socket that it creates on exit, and spawns fewer processes.

Maisem Ali	4669e7f7d5	cmd/containerboot: add iptables based MSS clamping for ingress/egress proxies In typical k8s setups, the MTU configured on the eth0 interfaces is typically 1500 which results in packets being dropped when they make it to proxy pods as the tailscale0 interface has a 1280 MTU. As the primary use of this functionality is TCP, add iptables based MSS clamping to allow connectivity. Updates #502 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago

James Tucker	d52ab181c3	Revert "ipn/ipnlocal: allow Split-DNS and default resolvers with WireGuard nodes" This reverts commit `c7ce4e07e5`. Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
James Tucker	c7ce4e07e5	ipn/ipnlocal: allow Split-DNS and default resolvers with WireGuard nodes The initial implementation directly mirrored the behavior of Tailscale exit nodes, where the WireGuard exit node DNS took precedence over other configuration. This adjusted implementation treats the WireGuard DNS resolvers as a lower precedence default resolver than the tailnet default resolver, and allows split DNS configuration as well. This also adds test coverage to the existing DNS selection behavior with respect to default resolvers and split DNS routes for Tailscale exit nodes above cap 25. There may be some refinement to do in the logic in those cases, as split DNS may not be working as we intend, though that would be a pre-existing and separate issue.

Tom DNetto	c08cf2a9c6	all: declare & plumb IPv6 masquerade address for peer This PR plumbs through awareness of an IPv6 SNAT/masquerade address from the wire protocol through to the low-level (tstun / wgengine). This PR is the first in two PRs for implementing IPv6 NAT support to/from peers. A subsequent PR will implement the data-plane changes to implement IPv6 NAT - this is just plumbing.

Andrew Dunham	d9ae7d670e	net/portmapper: add clientmetric for UPnP error codes This should allow us to gather a bit more information about errors that we encounter when creating UPnP mappings.

Maisem Ali	19a9d9037f	tailcfg: add NodeCapMap Like PeerCapMap, add a field to `tailcfg.Node` which provides a map of Capability to raw JSON messages which are deferred to be parsed later by the application code which cares about the specific capabilities. This effectively allows us to prototype new behavior without having to commit to a schema in tailcfg, and it also opens up the possibilities to develop custom behavior in tsnet applications w/o having to plumb through application specific data in the MapResponse.

Brad Fitzpatrick	9538e9f970	ipn/ipnlocal: keep internal map updated of latest Nodes post mutations We have some flaky integration tests elsewhere that have no one place to ask about the state of the world. This makes LocalBackend be that place (as it's basically there anyway) but doesn't yet add the ForTest accessor method. This adds a LocalBackend.peers map[NodeID]NodeView that is incrementally updated as mutations arrive. And then we start moving away from using NetMap.Peers at runtime (UpdateStatus no longer uses it now). And remove another copy of NodeView in the LocalBackend nodeByAddr map. Change that to point into b.peers instead. Future changes will then start streaming whole-node-granularity peer change updates to WatchIPNBus clients, tracking statefully per client what each has seen. This will get the GUI clients from receiving less of a JSON storm of updates all the time.
