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

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".

See https://github.com/tailscale/tailscale/issues/4924#issuecomment-1168201823 Arch uses a different login binary that makes the -h flag set the PAM service to "remote". So if they don't have that configured, don't pass -h. Thanks to @eddiezane for debugging!

Maisem Ali	c434e47f2d	ssh/tailssh: always use current time for policy evaluation ... Whenever the SSH policy changes we revaluate all open connections to make sure they still have access. This check was using the wrong timestamp and would match against expired policies, however this really isn't a problem today as we don't have policy that would be impacted by this check.

Maisem Ali	575aacb1e2	ssh/tailssh: terminate sessions on stdout copy failures ... Currently, killing a SCP copy with a Ctrl+C leaves the session hanging even though the stdout copy goroutine fails with an io.EOF. Taking a step back, when we are unable to send any more data back to the client we should just terminate the session as the client will stop getting any response from the server anyways.

Maisem Ali	7cd8c3e839	ssh/tailssh: terminate sessions when tailscaled shutsdown ... Ideally we would re-establish these sessions when tailscaled comes back up, however we do not do that yet so this is better than leaking the sessions.

Maisem Ali	3012a2e1ca	ssh/tailssh,ipn/ipnlocal: terminate any active sessions on `up --ssh=false` ... Currently the ssh session isn't terminated cleanly, instead the packets are just are no longer routed to the in-proc SSH server.

Currently if the policy changes and the session is logged in with local user "u1" and the new policy says they can only login with "u2" now, the user doesn't get kicked out because they had requested `rando@<ssh-host>` and the defaulting had made that go to `u1`.
