Will Norris	f8b0caa8c2	serve: fix hostname for custom http ports When using a custom http port like 8080, this was resulting in a constructed hostname of `host.tailnet.ts.net:8080.tailnet.ts.net` when looking up the serve handler. Instead, strip off the port before adding the MagicDNS suffix. Also use the actual hostname in `serve status` rather than the literal string "host".

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.

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).

Maisem Ali	fe95d81b43	ipn/ipnlocal,wgengine/netstack: move LocalBackend specifc serving logic to LocalBackend The netstack code had a bunch of logic to figure out if the LocalBackend should handle an incoming connection and then would call the function directly on LocalBackend.

Andrew Dunham	07eacdfe92	ipn/ipnlocal: renew certificates based on lifetime Instead of renewing certificates based on whether or not they're expired at a fixed 14-day period in the future, renew based on whether or not we're more than 2/3 of the way through the certificate's lifetime.

James Tucker	095d3edd33	ipn/ipnlocal: reenable profile tests on Windows This fix does not seem ideal, but the test infrastructure using a local goos doesn't seem to avoid all of the associated challenges, but is somewhat deeply tied to the setup. The core issue this addresses for now is that when run on Windows there can be no code paths that attempt to use an invalid UID string, which on Windows is described in [1]. For the goos="linux" tests, we now explicitly skip the affected migration code if runtime.GOOS=="windows", and for the Windows test we explicitly use the running users uid, rather than just the string "user1". We also now make the case where a profile exists and has already been migrated a non-error condition toward the outer API.

Mihai Parparita	7330aa593e	all: avoid repeated default interface lookups On some platforms (notably macOS and iOS) we look up the default interface to bind outgoing connections to. This is both duplicated work and results in logspam when the default interface is not available (i.e. when a phone has no connectivity, we log an error and thus cause more things that we will try to upload and fail). Fixed by passing around a netmon.Monitor to more places, so that we can use its cached interface state. Fixes #7850 Updates #7621 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	1 year ago
Mihai Parparita	4722f7e322	all: move network monitoring from wgengine/monitor to net/netmon We're using it in more and more places, and it's not really specific to our use of Wireguard (and does more just link/interface monitoring). Also removes the separate interface we had for it in sockstats -- it's a small enough package (we already pull in all of its dependencies via other paths) that it's not worth the extra complexity.

Mihai Parparita	d0906cda97	net/sockstats: expose debug info Exposes some internal state of the sockstats package via the C2N and PeerAPI endpoints, so that it can be used for debugging. For now this includes the estimated radio on percentage and a second-by-second view of the times the radio was active. Also fixes another off-by-one error in the radio on percentage that was leading to >100% values (if n seconds have passed since we started to monitor, there may be n + 1 possible seconds where the radio could have been on).

Aaron Klotz	90fd04cbde	ipn/ipnlocal, util/winutil/policy: modify Windows profile migration to load legacy prefs from within tailscaled I realized that a lot of the problems that we're seeing around migration and LocalBackend state can be avoided if we drive Windows pref migration entirely from within tailscaled. By doing it this way, tailscaled can automatically perform the migration as soon as the connection with the client frontend is established. Since tailscaled is already running as LocalSystem, it already has access to the user's local AppData directory. The profile manager already knows which user is connected, so we simply need to resolve the user's prefs file and read it from there. Of course, to properly migrate this information we need to also check system policies. I moved a bunch of policy resolution code out of the GUI and into a new package in util/winutil/policy.

Maisem Ali	e0d291ab8a	ipn/store: add support for stores to hook into a custom dialer For stores like k8s secrets we need to dial out to the k8s API as though Tailscale wasn't running. The issue currently only manifests when you try to use an exit node while running inside a k8s cluster and are trying to use Kubernetes secrets as the backing store.

Andrew Dunham	c98652c333	doctor/permissions: add new check to print process permissions Since users can run tailscaled in a variety of ways (root, non-root, non-root with process capabilities on Linux), this check will print the current process permissions to the log to aid in debugging.

shayne	3177ccabe5	ipn/ipnlocal: [serve/funnel] use actual SrcAddr as X-Forwarded-For (#7600 ) The reverse proxy was sending the ingressd IPv6 down as the X-Forwarded-For.

shayne	7908b6d616	ipn/ipnlocal: [serve] Trim mountPoint prefix from proxy path (#7334 ) This change trims the mountPoint from the request URL path before sending the request to the reverse proxy. Today if you mount a proxy at `/foo` and request to `/foo/bar/baz`, we leak the `mountPoint` `/foo` as part of the request URL's path. This fix makes removed the `mountPoint` prefix from the path so proxied services receive requests as if they were running at the root (`/`) path. This could be an issue if the app generates URLs (in HTML or otherwise) and assumes `/path`. In this case, those URLs will 404. With that, I still think we should trim by default and not leak the `mountPoint` (specific to Tailscale) into whatever app is hosted. If it causes an issue with URL generation, I'd suggest looking at configuring an app-specific path prefix or running Caddy as a more advanced solution.
