But why should insecure argument handling bugs (as per your recent SSH bulletin) be found after release ?

Those are an ancient class of bugs that should be picked up by any competent security review.

Is your theory that "any competent security review" will find every security hole in a product? Because that sure would be great if it were true. Unfortunately it does not match my experience.

i think its probably okay to drop it when you are this far deep into a conversation and the affiliation has already been stated multiple times in the existing comment chain.

Try to be civil

Every security hole ? No, of course not.

But things like insecure argument handling are low-hanging fruit for security auditors.

Insecure argument handling is not like the more advanced subtle vulnerabilities that we are seeing in some LLM-assisted reports these days. Insecure argument handling is 1990's security.

The fundamental problem remains that Tailscale has too many new "features" being added to it the whole time. New features means a whole bunch new code. Which increases bloat and exponentially increases the attack surface.

It would be really nice if you could stop shoehorning in every new feature you can think of. Remove some of the existing ones that don't really need to be there. And get your codebase back to a more focused state, get back to your roots as a VPN product.

Stop trying to be all things to all men, as the old saying goes.

It appears that you have a major bone to pick with Tailscale and direct replies to your concerns do not seem to matter. They have a good security track record and are extremely widely deployed. I don’t see the evidence for your assertions that it is bloated and insecure.

fwiw, we have been working on increasing modularity options in the client and a substantial volume of features can now be built out of the clients, see https://github.com/tailscale/tailscale/tree/main/feature for details.

If you are motivated to build a much less featureful client, it is easier now than it has ever been, and this work is ongoing.
