Mihai Parparita	2be951a582	cmd/tsconnect: fix null pointer dereference when DNS lookups fail ... If we never had a chance to open the SSH session we should not try to close it. Fixes #6089 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago

Maisem Ali	42f7ef631e	wgengine/netstack: use 72h as the KeepAlive Idle time for Tailscale SSH ... Setting TCP KeepAlives for Tailscale SSH connections results in them unnecessarily disconnecting. However, we can't turn them off completely as that would mean we start leaking sessions waiting for a peer to come back which may have gone away forever (e.g. if the node was deleted from the tailnet during a session).

Tom DNetto	d98305c537	cmd,ipn/ipnlocal,tailcfg: implement TKA disablement ... * Plumb disablement values through some of the internals of TKA enablement. * Transmit the node's TKA hash at the end of sync so the control plane understands each node's head. * Implement /machine/tka/disable RPC to actuate disablement on the control plane. There is a partner PR for the control server I'll send shortly. Signed-off-by: Tom DNetto <tom@tailscale.com>	2 years ago

Brad Fitzpatrick	ea24895e08	client/tailscale/apitype, tailcfg: delete never used mysterious PerDomain field ... It does nothing and never did and I don't think anybody remembers what the original goal for it was. Updates #5229 (fixes, but need to clean it up in another repo too) Change-Id: I81cc6ff44d6d2888bc43e9145437f4c407907ea6 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Brad Fitzpatrick	3336d08d59	cmd/tailscale/cli: make set without args print usage ... Make "tailscale set" by itself be equivalent to "tailscale set -h" rather than just say "you did it wrong" and make people do another -h step.

Brad Fitzpatrick	231b88cc51	control/controlclient: add start of noise+http2 upgrade test ... Basic HTTP/2-over-noise client test.

Anton Tolchanov	e25ab75795	net/dns: getting base DNS config is not supported on macOS ... Instead of returning a custom error, use ErrGetBaseConfigNotSupported that seems to be intended for this use case. This fixes DNS resolution on macOS clients compiled from source.

Joe Tsai	cfef47ddcc	wgengine: perform router reconfig for netlog-only changes (#6118) ... If the network logging configruation changes (and nothing else) we will tear down the network logger and start it back up. However, doing so will lose the router configuration state. Manually reconfigure it with the routing state. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Brad Fitzpatrick	dfe67afb4a	control/controlhttp: remove ClientConn.UntrustedUpgradeHeaders ... It was just added and unreleased but we've decided to go a different route. Details are in 5e9e57ecf5. Updates #5972 Change-Id: I49016af469225f58535f63a9b0fbe5ab6a5bf304 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Joe Tsai	b2035a1dca	cmd/netlogfmt: handle any stream of network logs (#6108) ... Make netlogfmt useful regardless of the exact schema of the input. If a JSON object looks like a network log message, then unmarshal it as one and then print it. This allows netlogfmt to support both a stream of JSON objects directly serialized from netlogtype.Message, or the schema returned by the /api/v2/tailnet/{{tailnet}}/network-logs API endpoint.

Joe Tsai	48ddb3af2a	wgengine/netlog: enforce hard limit on network log message sizes (#6109) ...

Joe Tsai	a3602c28bd	wgengine/netlog: embed the StableNodeID of the authoring node (#6105) ... This allows network messages to be annotated with which node it came from. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Joe Tsai	81fd259133	wgengine/magicsock: gather physical-layer statistics (#5925) ... There is utility in logging traffic statistics that occurs at the physical layer. That is, in order to send packets virtually to a particular tailscale IP address, what physical endpoints did we need to communicate with? This functionality logs IP addresses identical to what had always been logged in magicsock prior to #5823, so there is no increase in PII being logged. ExtractStatistics returns a mapping of connections to counts. The source is always a Tailscale IP address (without port), while the destination is some endpoint reachable on WAN or LAN. As a special case, traffic routed through DERP will use 127.3.3.40 as the destination address with the port being the DERP region. This entire feature is only enabled if data-plane audit logging is enabled on the tailnet (by default it is disabled). Example of type of information logged: ------------------------------------ Tx[P/s] Tx[B/s] Rx[P/s] Rx[B/s] PhysicalTraffic: 25.80 3.39Ki 38.80 5.57Ki 100.1.2.3 -> 143.11.22.33:41641 15.40 2.00Ki 23.20 3.37Ki 100.4.5.6 -> 192.168.0.100:41641 10.20 1.38Ki 15.60 2.20Ki 100.7.8.9 -> 127.3.3.40:2 0.20 6.40 0.00 0.00 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Brad Fitzpatrick	5e9e57ecf5	control/controlhttp: add AcceptHTTP hook to add coalesced Server->Client write ... New plan for #5972. Instead of sending the public key in the clear (from earlier unreleased 246274b8e9) where the client might have to worry about it being dropped or tampered with and retrying, we'll instead send it post-Noise handshake but before the HTTP/2 connection begins. This replaces the earlier extraHeaders hook with a different sort of hook that allows us to combine two writes on the wire in one packet. Updates #5972 Change-Id: I42cdf7c1859b53ca4dfa5610bd1b840c6986e09c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Joe Tsai	c21a3c4733	types/netlogtype: new package for network logging types (#6092) ... The netlog.Message type is useful to depend on from other packages, but doing so would transitively cause gvisor and other large packages to be linked in. Avoid this problem by moving all network logging types to a single package. We also update staticcheck to take in: 003d277bcf Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
Aaron Klotz	a44687e71f	wgengine/winnet: invoke some COM methods directly instead of through IDispatch. ... Intermittently in the wild we are seeing failures when calling `INetworkConnection::GetNetwork`. It is unclear what the root cause is, but what is clear is that the error is happening inside the object's `IDispatch` invoker (as opposed to the method implementation itself). This patch replaces our wrapper for `INetworkConnection::GetNetwork` with an alternate implementation that directly invokes the method, instead of using `IDispatch`. I also replaced the implementations of `INetwork::SetCategory` and `INetwork::GetCategory` while I was there. This patch is speculative and tightly-scoped so that we could possibly add it to a dot-release if necessary.

Mihai Parparita	d60f7fe33f	cmd/tsconnect: run wasm-opt on the generated wasm file ... Saves about 1.4MB from the generated wasm file. The Brotli size is basically unchanged (it's actually slightly larger, by 40K), suggesting that most of the size delta is due to not inlining and other changes that were easily compressible. However, it still seems worthwhile to have a smaller final binary, to reduce parse time and increase likelihood that we fit in the browser's disk cache. Actual performance appears to be unchanged.

Peter Cai	4597ec1037	net/dnscache: Handle 4-in-6 addresses in DNS responses ... On Android, the system resolver can return IPv4 addresses as IPv6-mapped addresses (i.e. `::ffff:a.b.c.d`). After the switch to `net/netip` (19008a3), this case is no longer handled and a response like this will be seen as failure to resolve any IPv4 addresses.
