Andrea Gottardo	6de6ab015f	net/dns: tweak DoH timeout, limit MaxConnsPerHost, require TLS 1.3 (#13564) ... Updates tailscale/tailscale#6148 This is the result of some observations we made today with @raggi. The DNS over HTTPS client currently doesn't cap the number of connections it uses, either in-use or idle. A burst of DNS queries will open multiple connections. Idle connections remain open for 30 seconds (this interval is defined in the dohTransportTimeout constant). For DoH providers like NextDNS which send keep-alives, this means the cellular modem will remain up more than expected to send ACKs if any keep-alives are received while a connection remains idle during those 30 seconds. We can set the IdleConnTimeout to 10 seconds to ensure an idle connection is terminated if no other DNS queries come in after 10 seconds. Additionally, we can cap the number of connections to 1. This ensures that at all times there is only one open DoH connection, either active or idle. If idle, it will be terminated within 10 seconds from the last query. We also observed all the DoH providers we support are capable of TLS 1.3. We can force this TLS version to reduce the number of packets sent/received each time a TLS connection is established.

Brad Fitzpatrick	a01b545441	control/control{client,http}: don't noise dial localhost:443 in http-only tests ... 1eaad7d3de regressed some tests in another repo that were starting up a control server on `http://127.0.0.1:nnn`. Because there was no https running, and because of a bug in 1eaad7d3de (which ended up checking the recently-dialed-control check twice in a single dial call), we ended up forcing only the use of TLS dials in a test that only had plaintext HTTP running. Instead, plumb down support for explicitly disabling TLS fallbacks and use it only when running in a test and using `http` scheme control plane URLs to 127.0.0.1 or localhost. This fixes the tests elsewhere. Updates #13597 Change-Id: I97212ded21daf0bd510891a278078daec3eebaa6 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 months ago

Andrea Gottardo	ed1ac799c8	net/captivedetection: set Timeout on net.Dialer (#13613) ... Updates tailscale/tailscale#1634 Updates tailscale/tailscale#13265 Captive portal detection uses a custom `net.Dialer` in its `http.Client`. This custom Dialer ensures that the socket is bound specifically to the Wi-Fi interface. This is crucial because without it, if any default routes are set, the outgoing requests for detecting a captive portal would bypass Wi-Fi and go through the default route instead. The Dialer did not have a Timeout property configured, so the default system timeout was applied. This caused issues in #13265, where we attempted to make captive portal detection requests over an IPsec interface used for Wi-Fi Calling. The call to `connect()` would fail and remain blocked until the system timeout (approximately 1 minute) was reached. In #13598, I simply excluded the IPsec interface from captive portal detection. This was a quick and safe mitigation for the issue. This PR is a follow-up to make the process more robust, by setting a 3 seconds timeout on any connection establishment on any interface (this is the same timeout interval we were already setting on the HTTP client).

Irbe Krumina	096b090caf	cmd/containerboot,kube,util/linuxfw: configure kube egress proxies to route to 1+ tailnet targets (#13531) ... * cmd/containerboot,kube,util/linuxfw: configure kube egress proxies to route to 1+ tailnet targets This commit is first part of the work to allow running multiple replicas of the Kubernetes operator egress proxies per tailnet service + to allow exposing multiple tailnet services via each proxy replica. This expands the existing iptables/nftables-based proxy configuration mechanism. A proxy can now be configured to route to one or more tailnet targets via a (mounted) config file that, for each tailnet target, specifies: - the target's tailnet IP or FQDN - mappings of container ports to which cluster workloads will send traffic to tailnet target ports where the traffic should be forwarded. Example configfile contents: { "some-svc": {"tailnetTarget":{"fqdn":"foo.tailnetxyz.ts.net","ports"{"tcp:4006:80":{"protocol":"tcp","matchPort":4006,"targetPort":80},"tcp:4007:443":{"protocol":"tcp","matchPort":4007,"targetPort":443}}}} } A proxy that is configured with this config file will configure firewall rules to route cluster traffic to the tailnet targets. It will then watch the config file for updates as well as monitor relevant netmap updates and reconfigure firewall as needed. This adds a bunch of new iptables/nftables functionality to make it easier to dynamically update the firewall rules without needing to restart the proxy Pod as well as to make it easier to debug/understand the rules: - for iptables, each portmapping is a DNAT rule with a comment pointing at the 'service',i.e: -A PREROUTING ! -i tailscale0 -p tcp -m tcp --dport 4006 -m comment --comment "some-svc:tcp:4006 -> tcp:80" -j DNAT --to-destination 100.64.1.18:80 Additionally there is a SNAT rule for each tailnet target, to mask the source address. - for nftables, a separate prerouting chain is created for each tailnet target and all the portmapping rules are placed in that chain. This makes it easier to look up rules and delete services when no longer needed. (nftables allows hooking a custom chain to a prerouting hook, so no extra work is needed to ensure that the rules in the service chains are evaluated). The next steps will be to get the Kubernetes Operator to generate the configfile and ensure it is mounted to the relevant proxy nodes.

Irbe Krumina	c62b0732d2	cmd/k8s-operator: remove auth key once proxy has logged in (#13612) ... The operator creates a non-reusable auth key for each of the cluster proxies that it creates and puts in the tailscaled configfile mounted to the proxies. The proxies are always tagged, and their state is persisted in a Kubernetes Secret, so their node keys are expected to never be regenerated, so that they don't need to re-auth. Some tailnet configurations however have seen issues where the auth keys being left in the tailscaled configfile cause the proxies to end up in unauthorized state after a restart at a later point in time. Currently, we have not found a way to reproduce this issue, however this commit removes the auth key from the config once the proxy can be assumed to have logged in. If an existing, logged-in proxy is upgraded to this version, its redundant auth key will be removed from the conffile. If an existing, logged-in proxy is downgraded from this version to a previous version, it will work as before without re-issuing key as the previous code did not enforce that a key must be present.

This commit also splits out TailnetDevice and RecorderTailnetDevice into separate structs because the URL field is specific to recorders, but we want a more generic struct for use in the ProxyGroup status field.
