Naman Sood	75254178a0	ipn/ipnlocal: don't bind localListener if its context is canceled (#12621 ) The context can get canceled during backoff, and binding after that makes the listener impossible to close afterwards. Fixes #12620. Signed-off-by: Naman Sood <mail@nsood.in>	5 months ago
Andrew Dunham	45d2f4301f	proxymap, various: distinguish between different protocols Previously, we were registering TCP and UDP connections in the same map, which could result in erroneously removing a mapping if one of the two connections completes while the other one is still active. Add a "proto string" argument to these functions to avoid this. Additionally, take the "proto" argument in LocalAPI, and plumb that through from the CLI and add a new LocalClient method.

Maisem Ali	491483d599	cmd/viewer,type/views: add MapSlice for maps of slices This abstraction provides a nicer way to work with maps of slices without having to write out three long type params. This also allows it to provide an AsMap implementation which copies the map and the slices at least. Updates tailscale/corp#20910 Signed-off-by: Maisem Ali <maisem@tailscale.com>	6 months ago

Tyler Smalley	90eb5379f4	ipn/ipnlocal: log and don't return full file serve error (#10174 ) Previously we would return the full error from Stat or Open, possibily exposing the full file path. This change will log the error and return the generic error message "an error occurred reading the file or directory".

Will Norris	1cb8d2ffdd	ipn/ipnlocal: only call serve handler if non-nil return early if handler is nil. Go ahead and return the error from handler, though in this case the caller isn't doing anything with it (which has always been the case).

Will Norris	b7918341f9	ipn/ipnlocal: call serve handler for local traffic Tailscale serve maintains a set of listeners so that serve traffic from the local device can be properly served when running in kernel networking mode. #10177 refactored that logic so that it could be reused by the internal web client as well. However, in my refactoring I missed actually calling the serve handler to handle the traffic. Updates #10177 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
Will Norris	09de240934	ipn/ipnlocal: allow connecting to local web client The local web client has the same characteristic as tailscale serve, in that it needs a local listener to allow for connections from the local machine itself when running in kernel networking mode. This change renames and adapts the existing serveListener to allow it to be used by the web client as well. Updates tailscale/corp#14335 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago

Maisem Ali	24f322bc43	ipn/ipnlocal: do unexpired cert renewals in the background We were eagerly doing a synchronous renewal of the cert while trying to serve traffic. Instead of that, just do the cert renewal in the background and continue serving traffic as long as the cert is still valid. This regressed in `c1ecae13ab` when we introduced ARI support and were trying to make the experience of `tailscale cert` better. However, that ended up regressing the experience for tsnet as it would not always doing the renewal synchronously. Fixes #9783 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Maisem Ali	319607625f	ipn/ipnlocal: fix log spam from now expected paths These log paths were actually unexpected until the refactor in `fe95d81b43`. This moves the logs to the callsites where they are actually unexpected. Fixes #9670 Signed-off-by: Maisem Ali <maisem@tailscale.com>	1 year ago
Marwan Sulaiman	651620623b	ipn/ipnlocal: close foreground sessions on SetServeConfig This PR ensures zombie foregrounds are shutdown if a new ServeConfig is created that wipes the ongoing foreground ones.

Marwan Sulaiman	50990f8931	ipn, ipn/ipnlocal: add Foreground field for ServeConfig This PR adds a new field to the serve config that can be used to identify which serves are in "foreground mode" and then can also be used to ensure they do not get persisted to disk so that if Tailscaled gets ungracefully shutdown, the reloaded ServeConfig will not have those ports opened.

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`.

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.

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.

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.

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.

Maisem Ali	b797f773c7	ipn/ipnlocal: add support for funnel in tsnet Previously the part that handled Funnel connections was not aware of any listeners that tsnet.Servers might have had open so it would check against the ServeConfig and fail. Adding a ServeConfig for a TCP proxy was also not suitable in this scenario as that would mean creating two different listeners and have one forward to the other, which really meant that you could not have funnel and tailnet-only listeners on the same port. This also introduces the ipn.FunnelConn as a way for users to identify whether the call is coming over funnel or not. Currently it only holds the underlying conn and the target as presented in the "Tailscale-Ingress-Target" header. Signed-off-by: Maisem Ali <maisem@tailscale.com>	2 years ago
