Claire Wang	e3d6236606	winutil: refactor methods to get values from registry to also return (#9536) ... errors Updates tailscale/corp#14879 Signed-off-by: Claire Wang <claire@tailscale.com>	8 months ago
Val	c608660d12	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>	8 months ago

Ensure that when there is an event on a Tailscale managed Ingress or Service child resource, the right parent type gets reconciled Updates tailscale/tailscale#502 Signed-off-by: Irbe Krumina <irbe@tailscale.com>	8 months ago
Marwan Sulaiman	651620623b	ipn/ipnlocal: close foreground sessions on SetServeConfig ... This PR ensures zombie foregrounds are shutdown if a new ServeConfig is created that wipes the ongoing foreground ones. For example, "tailscale serve|funnel reset|off" should close all open sessions. Updates #8489 Signed-off-by: Marwan Sulaiman <marwan@tailscale.com>	8 months ago
Andrew Dunham	530aaa52f1	net/dns: retry forwarder requests over TCP ... We weren't correctly retrying truncated requests to an upstream DNS server with TCP. Instead, we'd return a truncated request to the user, even if the user was querying us over TCP and thus able to handle a large response. Also, add an envknob and controlknob to allow users/us to disable this behaviour if it turns out to be buggy (✨ DNS ✨).

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>	8 months ago
Brad Fitzpatrick	546506a54d	ipn/ipnlocal: add a test for recent WhoIs regression ... This would've prevented #9470. This used to pass, fails as of 9538e9f970, and passes again once #9472 is in.

Joe Tsai	ae89482f25	ipn/ipnlocal: fix LocalBackend.WhoIs for self (#9472) ... 9538e9f970 broke LocalBackend.WhoIs where you can no longer lookup yourself in WhoIs. This occurs because the LocalBackend.peers map only contains peers. If we fail to lookup a peer, double-check whether it is ourself.

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>	9 months 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.

Maisem Ali	3056a98bbd	net/tstun: add better logging of natV4Config ... It might as well have been spewing out gibberish.

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.

Maisem Ali	d06b48dd0a	tailcfg: add RawMessage ... This adds a new RawMessage type backed by string instead of the json.RawMessage which is backed by []byte.
