shayne	43f7ec48ca	funnel: change references from alpha to beta (#7613) ... Updates CLI and docs to reference Funnel as beta Signed-off-by: Shayne Sweeney <shayne@tailscale.com>	2 years ago
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. This update uses the actual remote addr. Updates tailscale/corp#9914 Signed-off-by: Shayne Sweeney <shayne@tailscale.com>	2 years ago
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	9d8b7a7383	ipn/store/kubestore: handle "/" in ipn.StateKeys ... Kubernetes doesn't allow slashes as keys in secrets, replace them with "__".

Will Norris	57a008a1e1	all: pass log IDs as the proper type rather than strings ... This change focuses on the backend log ID, which is the mostly commonly used in the client. Tests which don't seem to make use of the log ID just use the zero value. Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Will Norris	f13b8bf0cf	log: use logtail to log and upload sockstat logs ... Switch to using logtail for logging sockstat logs. Always log locally (on supported platforms), but disable automatic uploading. Change existing c2n sockstats request to trigger upload to log server and return log ID.

Mihai Parparita	731688e5cc	ipn/localapi: add endpoint for adding debug log entries ... Allows the iOS and macOS apps to include their frontend logs when generating bug reports (tailscale/corp#9982). Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	97b6d3e917	sockstats: remove per-interface stats from Get ... They're not needed for the sockstats logger, and they're somewhat expensive to return (since they involve the creation of a map per label). We now have a separate GetInterfaces() method that returns them instead (which we can still use in the PeerAPI debug endpoint). If changing sockstatlog to sample at 10,000 Hz (instead of the default of 10Hz), the CPU usage would go up to 59% on a iPhone XS. Removing the per-interface stats drops it to 20% (a no-op implementation of Get that returns a fixed value is 16%).

Mihai Parparita	b64d78d58f	sockstats: refactor validation to be opt-in ... Followup to #7499 to make validation a separate function ( GetWithValidation vs. Get). This way callers that don't need it don't pay the cost of a syscall per active TCP socket. Also clears the conn on close, so that we don't double-count the stats. Also more consistently uses Go doc comments for the exported API of the sockstats package. Updates tailscale/corp#9230 Updates #3363 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago

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

Mihai Parparita	f4f8ed98d9	sockstats: add validation for TCP socket stats ... We can use the TCP_CONNECTION_INFO getsockopt() on Darwin to get OS-collected tx/rx bytes for TCP sockets. Since this API is not available for UDP sockets (or on Linux/Android), we can't rely on it for actual stats gathering. However, we can use it to validate the stats that we collect ourselves using read/write hooks, so that we can be more confident in them. We do need additional hooks from the Go standard library (added in tailscale/go#59) to be able to collect them.

Andrew Dunham	be107f92d3	wgengine/magicsock: track per-endpoint changes in ringbuffer ... This change adds a ringbuffer to each magicsock endpoint that keeps a fixed set of "changes"–debug information about what updates have been made to that endpoint. Additionally, this adds a LocalAPI endpoint and associated "debug peer-status" CLI subcommand to fetch the set of changes for a given IP or hostname.

Andrew Dunham	df2561f6a2	ipn/ipnlocal: stop netmap expiry timer when resetting control client ... This prevents a panic where we synthesize a new netmap in setClientStatus after we've shut down and nil'd out the controlclient, since that function expects to be called while connected to control.

Andrew Dunham	3f8e8b04fd	cmd/tailscale, cmd/tailscaled: move portmapper debugging into tailscale CLI ... The debug flag on tailscaled isn't available in the macOS App Store build, since we don't have a tailscaled binary; move it to the 'tailscale debug' CLI that is available on all platforms instead, accessed over LocalAPI.

Mihai Parparita	9cb332f0e2	sockstats: instrument networking code paths ... Uses the hooks added by tailscale/go#45 to instrument the reads and writes on the major code paths that do network I/O in the client. The convention is to use "<package>.<type>:<label>" as the annotation for the responsible code path. Enabled on iOS, macOS and Android only, since mobile platforms are the ones we're most interested in, and we are less sensitive to any throughput degradation due to the per-I/O callback overhead (macOS is also enabled for ease of testing during development). For now just exposed as counters on a /v0/sockstats PeerAPI endpoint. We also keep track of the current interface so that we can break out the stats by interface.

Joe Tsai	0d19f5d421	all: replace logtail.{Public,Private}ID with logid.{Public,Private}ID (#7404) ... The log ID types were moved to a separate package so that code that only depend on log ID types do not need to link in the logic for the logtail client itself. Not all code need the logtail client.

David Crawshaw	768df4ff7a	tsnet: add a LocalAPI listener on loopback, with basic auth ...

Mihai Parparita	780c56e119	ipn/ipnlocal: add delegated interface information to /interfaces PeerAPI handler ... Exposes the delegated interface data added by #7248 in the debug endpoint. I would have found it useful when working on that PR, and it may be handy in the future as well. Also makes the interfaces table slightly easier to parse by adding borders to it. To make then nicer-looking, the CSP was relaxed to allow inline styles. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago

Mihai Parparita	fa932fefe7	net/interfaces: redo how we get the default interface on macOS and iOS ... With #6566 we added an external mechanism for getting the default interface, and used it on macOS and iOS (see tailscale/corp#8201). The goal was to be able to get the default physical interface even when using an exit node (in which case the routing table would say that the Tailscale utun* interface is the default). However, the external mechanism turns out to be unreliable in some cases, e.g. when multiple cellular interfaces are present/toggled (I have occasionally gotten my phone into a state where it reports the pdp_ip1 interface as the default, even though it can't actually route traffic). It was observed that `ifconfig -v` on macOS reports an "effective interface" for the Tailscale utn* interface, which seems promising. By examining the ifconfig source code, it turns out that this is done via a SIOCGIFDELEGATE ioctl syscall. Though this is a private API, it appears to have been around for a long time (e.g. it's in the 10.13 xnu release at https://opensource.apple.com/source/xnu/xnu-4570.41.2/bsd/net/if_types.h.auto.html) and thus is unlikely to go away. We can thus use this ioctl if the routing table says that a utun* interface is the default, and go back to the simpler mechanism that we had before #6566.

Mihai Parparita	7d204d89c2	ipn/ipnlocal: fix passthrough of formatting arguments in PeerAPI doctor output ... Followup to #7235, we were not treating the formatting arguments as variadic.

Mihai Parparita	6799ef838f	ipn/ipnlocal: add PeerAPI endpoint for doctor output ... Useful when debugging issues (e.g. to see the full routing table), and easier to refer to the output via a browser than trying to read it from the logs generated by `bugreport --diagnose`.

Mihai Parparita	62f4df3257	net/interfaces, net/netns: add node attributes to control default interface getting and binding ... With #6566 we started to more aggressively bind to the default interface on Darwin. We are seeing some reports of the wrong cellular interface being chosen on iOS. To help with the investigation, this adds to knobs to control the behavior changes: - CapabilityDebugDisableAlternateDefaultRouteInterface disables the alternate function that we use to get the default interface on macOS and iOS (implemented in tailscale/corp#8201). We still log what it would have returned so we can see if it gets things wrong. - CapabilityDebugDisableBindConnToInterface is a bigger hammer that disables binding of connections to the default interface altogether.

Maisem Ali	0fd2f71a1e	ipn/ipnlocal: use presence of NodeID to identify logins ... The profileManager was using the LoginName as a proxy to figure out if the profile had logged in, however the LoginName is not present if the node was created with an Auth Key that does not have an associated user.

Andrew Dunham	6d84f3409b	ipn/ipnlocal: handle more edge cases in netmap expiry timer ... We now handle the case where the NetworkMap.SelfNode has already expired and do not return an expiry time in the past (which causes an ~infinite loop of timers to fire). Additionally, we now add an explicit check to ensure that the next expiry time is never before the current local-to-the-system time, to ensure that we don't end up in a similar situation due to clock skew. Finally, we add more tests for this logic to ensure that we don't regress on these edge cases.
