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.

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.

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.

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.

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	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.

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.

Mihai Parparita	4973956419	ipn/ipnlocal: add /reset-auth LocalAPI endpoint ... The iOS has a command to reset the persisted state of the app, but it was doing its own direct keychain manipulation.

This clears the same state as the iOS implementation (tailscale/corp#3186), that is the machine key and preferences (which includes the node key).

They changed a type in their SDK which meant others using the AWS APIs in their Go programs (with newer AWS modules in their caller go.mod) and then depending on Tailscale (for e.g. tsnet) then couldn't compile ipn/store/awsstore. Thanks to @thisisaaronland for bringing this up. Fixes #7019 Change-Id: I8d2919183dabd6045a96120bb52940a9bb27193b Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

salman	eec734a578	ipn/{ipnlocal,localapi}: ensure watcher is installed before /watch-ipn-bus/ responds with 200 ... This change delays the first flush in the /watch-ipn-bus/ handler until after the watcher has been successfully installed on the IPN bus. It does this by adding a new onWatchAdded callback to LocalBackend.WatchNotifications(). Without this, the endpoint returns a 200 almost immediatly, and only then installs a watcher for IPN events. This means there's a small window where events could be missed by clients after calling WatchIPNBus(). Fixes tailscale/corp#8594. Signed-off-by: salman <salman@tailscale.com>	2 years ago

Andrew Dunham	3a018e51bb	ipn/ipnlocal: move handling of expired nodes to LocalBackend ... In order to be able to synthesize a new NetMap when a node expires, have LocalBackend start a timer when receiving a new NetMap that fires slightly after the next node expires. Additionally, move the logic that updates expired nodes into LocalBackend so it runs on every netmap (whether received from controlclient or self-triggered).
