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. Time to remove them. Done with: perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build') Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
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. This makes it a pointer, which fixes the JSON roundtrip. This was introduced in 0957bc5af2. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
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.

To collect some data on how widespread this is and whether there's any correlation between different versions of Windows, etc. Updates #4811 Change-Id: I003041d0d7e61d2482acd8155c1a4ed413a2c5c4 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

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.

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.

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) ... 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

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.

Andrew Dunham	223126fe5b	cmd/derper, net/netcheck: add challenge/response to generate_204 endpoint ... 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. We can then check for the expected response to verify whether we're being MITM'd.

Mihai Parparita	9d04ffc782	net/wsconn: add back custom wrapper for turning a websocket.Conn into a net.Conn ... We removed it in #4806 in favor of the built-in functionality from the nhooyr.io/websocket package. However, it has an issue with deadlines that has not been fixed yet (see nhooyr/websocket#350). Temporarily go back to using a custom wrapper (using the fix from our fork) so that derpers will stop closing connections too aggressively.

Mihai Parparita	63ad49890f	cmd/tsconnect: pre-compress main.wasm when building the NPM package ... This way we can do that once (out of band, in the GitHub action), instead of increasing the time of each deploy that uses the package. .wasm is removed from the list of automatically pre-compressed extensions, an OSS bump and small change on the corp side is needed to make use of this change.

Brad Fitzpatrick	e24de8a617	ssh/tailssh: add password-forcing workaround for buggy SSH clients ... If the username includes a suffix of +password, then we accept password auth and just let them in like it were no auth.

Anton Tolchanov	c070d39287	cmd/tailscaled: handle tailscaled symlink on macOS ... When Tailscale is installed via Homebrew, `/usr/local/bin/tailscaled` is a symlink to the actual binary. Now when `tailscaled install-system-daemon` runs, it will not attempt to overwrite that symlink if it already points to the tailscaled binary. However, if executed binary and the link target differ, the path will he overwritten - this can happen when a user decides to replace Homebrew-installed tailscaled with a one compiled from source code.

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.
