Brad Fitzpatrick	45b7e8c23c	cmd/tailscale: make tailscale cert --serve-demo accept optional listen argument ... Change-Id: I48f2f4f74c9996b9ed4bee02c61f125d42154a34 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Joe Tsai	9116e92718	cmd/netlogfmt: new package to pretty print network traffic logs (#5930) ... This package parses a JSON stream of netlog.Message from os.Stdin and pretty prints the contents as a stream of tables. It supports reverse lookup of tailscale IP addresses if given an API key and the tailnet that these traffic logs belong to. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago

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.

Joe Tsai	f9120eee57	wgengine: start network logger in Userspace.Reconfig (#5908) ... If the wgcfg.Config is specified with network logging arguments, then Userspace.Reconfig starts up an asynchronous network logger, which is shutdown either upon Userspace.Close or when Userspace.Reconfig is called again without network logging or route arguments.

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. This exists purely for SSH clients that get confused by seeing success to their initial auth type "none".

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.

Mihai Parparita	92ad56ddcb	cmd/tsconnect: close the SSH session an unload event instead of beforeunload ... The window may not end up getting unloaded (if other beforeunload handlers prevent the event), thus we should only close the SSH session if it's truly getting unloaded.

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	2c447de6cc	cmd/tailscaled: use explicit equal sign in --port=$PORT in tailscaled.service ... Personal preference (so it's obvious it's not a bool flag), but it also matches the --state= before it. Bonus: stop allowing PORT to sneak in extra flags to be passed as their own arguments, as $FOO and ${FOO} expand differently.

Berk D.

Brad Fitzpatrick	65c24b6334	envknob: generalize Windows tailscaled-env.txt support ... ipnserver previously had support for a Windows-only environment variable mechanism that further only worked when Windows was running as a service, not from a console. But we want it to work from tailscaed too, and we want it to work on macOS and Synology. So move it to envknob, now that envknob can change values at runtime post-init. A future change will wire this up for more platforms, and do something more for CLI flags like --port, which the bug was originally about.

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.
