Joe Tsai	61886e031e	ssh/tailssh: fix double race condition with non-pty command (#8405 ) There are two race conditions in output handling. The first race condition is due to a misuse of exec.Cmd.StdoutPipe. The documentation explicitly forbids concurrent use of StdoutPipe with exec.Cmd.Wait (see golang/go#60908) because Wait will close both sides of the pipe once the process ends without any guarantees that all data has been read from the pipe. To fix this, we allocate the os.Pipes ourselves and manage cleanup ourselves when the process has ended. The second race condition is because sshSession.run waits upon exec.Cmd to finish and then immediately proceeds to call ss.Exit, which will close all output streams going to the SSH client. This may interrupt any asynchronous io.Copy still copying data. To fix this, we close the write-side of the os.Pipes after the process has finished (and before calling ss.Exit) and synchronously wait for the io.Copy routines to finish.

Derek Burdick	dc5bc32d8f	ssh/tailssh: change to user directory when running login/command On redhat 9 and similarly locked down systems, root user does not have access to a users directory.

Sonia Appasamy	0f5090c526	ipn/ipnlocal: add docs header to serve HTTP proxy Adds a `Tailscale-Headers-Info` header whenever the `Tailscale-User-` headers are filled from the HTTP proxy handler. Planning on hooking this shorturl up to KB docs about the header values (i.e. what's a login name vs. display name) and security considerations to keep in mind while using these headers - notibly that they can also be filled from external requests that do not hit tailscaled.

valscale	88097b836a	prober: allow monitoring of nodes marked as STUN only in default derpmap (#8391 ) prober uses NewRegionClient() to connect to a derper using a faked up single-node region, but NewRegionClient() fails to connect if there is no non-STUN only client in the region. Set the STUN only flag to false before we call NewRegionClient() so we can monitor nodes marked as STUN only in the default derpmap.

Maisem Ali	2ae670eb71	ssh/tailssh: work around lack of scontext in SELinux Trying to SSH when SELinux is enforced results in errors like: ``` ➜ ~ ssh ec2-user@<ip> Last login: Thu Jun 1 22:51:44 from <ip2> ec2-user: no shell: Permission denied Connection to <ip> closed. ``` while the `/var/log/audit/audit.log` has ``` type=AVC msg=audit(1685661291.067:465): avc: denied { transition } for pid=5296 comm="login" path="/usr/bin/bash" dev="nvme0n1p1" ino=2564 scontext=system_u:system_r:unconfined_service_t:s0 tcontext=unconfined_u:unconfined_r:unconfined_t:s0 tclass=process permissive=0 ``` The right fix here would be to somehow install the appropriate context when tailscale is installed on host, but until we figure out a way to do that stop using the `login` cmd in these situations.

Sonia Appasamy	e1cdcf7708	ipn/ipnlocal: add identity headers to HTTP serve proxy Adds two new headers to HTTP serve proxy: - `Tailscale-User-Login`: Filled with requester's login name. - `Tailscale-User-Name`: Filled with requester's display name. These headers only get filled when the SrcAddr is associated with a non-tagged (i.e. user-owned) node within the client's Tailnet. The headers are passed through empty when the request originated from another tailnet, or the public internet (via funnel).

Andrew Dunham	f077b672e4	net/dns/recursive: add initial implementation of recursive DNS resolver We've talked in the past about reworking how bootstrap DNS works to instead do recursive DNS resolution from the root; this would better support on-prem customers and Headscale users where the DERP servers don't currently resolve their DNS server. This package is an initial implementation of recursive resolution for A and AAAA records.

Andrew Dunham	2a9d46c38f	wgengine/magicsock: prefer private endpoints to public ones Switch our best address selection to use a scoring-based approach, where we boost each address based on whether it's a private IP or IPv6. For users in cloud environments, this biases endpoint selection towards using an endpoint that is less likely to cost the user money, and should be less surprising to users. This also involves updating the tests to not use private IPv4 addresses; other than that change, the behaviour should be identical for existing endpoints.
