Joe Tsai	9a05cdd2b5	syncs: add Map (#6260) ... Map is a concurrent safe map that is a trivial wrapper over a Go map and a sync.RWMutex. It is optimized for use-cases where the entries change often, which is the opposite use-case of what sync.Map is optimized for. The API is patterned off of sync.Map, but made generic.

Brad Fitzpatrick	db2cc393af	util/dirwalk, metrics, portlist: add new package for fast directory walking ... This is similar to the golang.org/x/tools/internal/fastwalk I'd previously written but not recursive and using mem.RO. The metrics package already had some Linux-specific directory reading code in it. Move that out to a new general package that can be reused by portlist too, which helps its scanning of all /proc files: name old time/op new time/op delta FindProcessNames-8 2.79ms ± 6% 2.45ms ± 7% -12.11% (p=0.000 n=10+10) name old alloc/op new alloc/op delta FindProcessNames-8 62.9kB ± 0% 33.5kB ± 0% -46.76% (p=0.000 n=9+10) name old allocs/op new allocs/op delta FindProcessNames-8 2.25k ± 0% 0.38k ± 0% -82.98% (p=0.000 n=9+10) Change-Id: I75db393032c328f12d95c39f71c9742c375f207a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	da8def8e13	all: remove old +build tags ... The //go:build syntax was introduced in Go 1.17: https://go.dev/doc/go1.17#build-lines gofmt has kept the +build and go:build lines in sync since then, but enough time has passed.

Maisem Ali	6afe26575c	ipn: make Notify.Prefs be a *ipn.PrefsView ... It is currently a `ipn.PrefsView` which means when we do a JSON roundtrip, we go from an invalid Prefs to a valid one.

David Anderson	76904b82e7	cmd/containerboot: PID1 for running tailscaled in a container. ... This implements the same functionality as the former run.sh, but in Go and with a little better awareness of tailscaled's lifecycle. Also adds TS_AUTH_ONCE, which fixes the unfortunate behavior run.sh had where it would unconditionally try to reauth every time if you gave it an authkey, rather than try to use it only if auth is actually needed. This makes it a bit nicer to deploy these containers in automation, since you don't have to run the container once, then go and edit its definition to remove authkeys.

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	c21a3c4733	types/netlogtype: new package for network logging types (#6092) ...

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.

The Lufthansa in-flight wifi generates a synthetic 204 response to the DERP server's /generate_204 endpoint. This PR adds a basic challenge/response to the endpoint; something sufficiently complicated that it's unlikely to be implemented by a captive portal.

David Anderson	bdf3d2a63f	cmd/pgproxy: open-source our postgres TLS-enforcing proxy. ... From the original commit that implemented it: It accepts Postgres connections over Tailscale only, dials out to the configured upstream database with TLS (using strong settings, not the swiss cheese that postgres defaults to), and proxies the client through. It also keeps an audit log of the sessions it passed through, along with the Tailscale-provided machine and user identity of the connecting client. In our other repo, this was: commit 92e5edf98e8c2be362f564a408939a5fc3f8c539, Change-Id I742959faaa9c7c302bc312c7dc0d3327e677dc28.

Aaron Klotz	44f13d32d7	cmd/tailscaled, util/winutil: log Windows service diagnostics when the wintun device fails to install ... I added new functions to winutil to obtain the state of a service and all its depedencies, serialize them to JSON, and write them to a Logf. When tstun.New returns a wrapped ERROR_DEVICE_NOT_AVAILABLE, we know that wintun installation failed. We then log the service graph rooted at "NetSetupSvc". We are interested in that specific service because network devices will not install if that service is not running.

Brad Fitzpatrick	45a3de14a6	cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support ... As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically. Making it easier to set flags for other platforms is tracked in #5114.

Brad Fitzpatrick	58abae1f83	net/dns/{publicdns,resolver}: add NextDNS DoH support ... NextDNS is unique in that users create accounts and then get user-specific DNS IPs & DoH URLs. For DoH, the customer ID is in the URL path. For IPv6, the IP address includes the customer ID in the lower bits. For IPv4, there's a fragile "IP linking" mechanism to associate your public IPv4 with an assigned NextDNS IPv4 and that tuple maps to your customer ID. We don't use the IP linking mechanism. Instead, NextDNS is DoH-only. Which means using NextDNS necessarily shunts all DNS traffic through 100.100.100.100 (programming the OS to use 100.100.100.100 as the global resolver) because operating systems can't usually do DoH themselves. Once it's in Tailscale's DoH client, we then connect out to the known NextDNS IPv4/IPv6 anycast addresses. If the control plane sends the client a NextDNS IPv6 address, we then map it to the corresponding NextDNS DoH with the same client ID, and we dial that DoH server using the combination of v4/v6 anycast IPs.
