Brad Fitzpatrick	ea4425d8a9	ipn/ipnlocal, wgengine/magicsock: move UpdateStatus stuff around Upcoming work on incremental netmap change handling will require some replumbing of which subsystems get notified about what. Done naively, it could break "tailscale status --json" visibility later. To make sure I understood the flow of all the updates I was rereading the status code and realized parts of ipnstate.Status were being populated by the wrong subsystems. The engine (wireguard) and magicsock (data plane, NAT traveral) should only populate the stuff that they uniquely know. The WireGuard bits were fine but magicsock was populating stuff stuff that LocalBackend could've better handled, so move it there.

Brad Fitzpatrick	4511e7d64e	ipn/ipnstate: add PeerStatus.AltSharerUserID, stop mangling Node.User In `b987b2ab18` (2021-01-12) when we introduced sharing we mapped the sharer to the userid at a low layer, mostly to fix the display of "tailscale status" and the client UIs, but also some tests. The commit earlier today, `7dec09d169`, removed the 2.5yo option to let clients disable that automatic mapping, as clearly we were never getting around to it. This plumbs the Sharer UserID all the way to ipnstatus so the CLI itself can choose to print out the Sharer's identity over the node's original owner. Then we stop mangling Node.User and let clients decide how they want to render things. To ease the migration for the Windows GUI (which currently operates on tailcfg.Node via the NetMap from WatchIPNBus, instead of PeerStatus), a new method Node.SharerOrUser is added to do the mapping of Sharer-else-User.

Brad Fitzpatrick	d8191a9813	ipn/ipnlocal: fix regression in printf arg type I screwed this up in `58a4fd43d` as I expected. I even looked out for cases like this (because this always happens) and I still missed it. Vet doesn't flag these because they're not the standard printf funcs it knows about.

Andrew Lytvynov	c1ecae13ab	ipn/{ipnlocal,localapi}: actually renew certs before expiry (#8731 ) While our `shouldStartDomainRenewal` check is correct, `getCertPEM` would always bail if the existing cert is not expired. Add the same `shouldStartDomainRenewal` check to `getCertPEM` to make it proceed with renewal when existing certs are still valid but should be renewed. The extra check is expensive (ARI request towards LetsEncrypt), so cache the last check result for 1hr to not degrade `tailscale serve` performance. Also, asynchronous renewal is great for `tailscale serve` but confusing for `tailscale cert`. Add an explicit flag to `GetCertPEM` to force a synchronous renewal for `tailscale cert`.

Charlotte Brandhorst-Satzkorn	35bdbeda9f	cli: introduce exit-node subcommand to list and filter exit nodes This change introduces a new subcommand, `exit-node`, along with a subsubcommand of `list` and a `--filter` flag. Exit nodes without location data will continue to be displayed when `status` is used. Exit nodes with location data will only be displayed behind `exit-node list`, and in status if they are the active exit node. The `filter` flag can be used to filter exit nodes with location data by country. Exit nodes with Location.Priority data will have only the highest priority option for each country and city listed. For countries with multiple cities, a <Country> <Any> option will be displayed, indicating the highest priority node within that country.

Maisem Ali	1ecc16da5f	tailcfg,ipn/ipnlocal,wgengine: add values to PeerCapabilities Define PeerCapabilty and PeerCapMap as the new way of sending down inter-peer capability information.

Instead add the ability to send down raw JSON messages that are opaque to Tailscale but provide the applications to define them however they wish. Also update accessors to use the new values.

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.

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.

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).
