Rhea Ghosh	557ddced6c	{ipn/ipnlocal, taildrop}: move put logic to taildrop (#9680 ) Cleaning up taildrop logic for sending files. Updates tailscale/corp#14772 Signed-off-by: Rhea Ghosh <rhea@tailscale.com> Co-authored-by: Joe Tsai <joetsai@digital-static.net>	1 year ago
Joe Tsai	c42398b5b7	ipn/ipnlocal: cleanup incomingFile (#9678 ) This is being moved to taildrop, so clean it up to stop depending on so much unreleated functionality by removing a dependency on peerAPIHandler.

Rhea Ghosh	dc1c7cbe3e	taildrop: initial commit of taildrop functionality refactoring (#9676 ) Over time all taildrop functionality will be contained in the taildrop package. This will include end to end unit tests. This is simply the first smallest piece to move over. There is no functionality change in this commit.

Brad Fitzpatrick	b4816e19b6	hostinfo, ipnlocal: flesh out Wake-on-LAN support, send MACs, add c2n sender This optionally uploads MAC address(es) to control, then adds a c2n handler so control can ask a node to send a WoL packet. Updates #306 RELNOTE=now supports waking up peer nodes on your LAN via Wake-on-LAN packets Change-Id: Ibea1275fcd2048dc61d7059039abfbaf1ad4f465 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago

Joe Tsai	5473d11caa	ipn/ipnlocal: perform additional sanity check in diskPath (#9500 ) Use filepath.IsLocal to further validate the baseName. Updates tailscale/corp#14772 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	1 year ago
Tom DNetto	c08cf2a9c6	all: declare & plumb IPv6 masquerade address for peer This PR plumbs through awareness of an IPv6 SNAT/masquerade address from the wire protocol through to the low-level (tstun / wgengine). This PR is the first in two PRs for implementing IPv6 NAT support to/from peers. A subsequent PR will implement the data-plane changes to implement IPv6 NAT - this is just plumbing.

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. Previously, this was unstructured and you could only send down strings which got too limiting for certain usecases. 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.

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	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). Updates tailscale/corp#9230 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	03b2c44a21	ipn/ipnlocal: more explicitly say if sockstats are not available Makes it more apparent in the PeerAPI endpoint that the client was not built with the appropriate toolchain or build tags. Updates tailscale/corp#9230 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.

Mihai Parparita	6ac6ddbb47	sockstats: switch label to enum Makes it cheaper/simpler to persist values, and encourages reuse of labels as opposed to generating an arbitrary number. Updates tailscale/corp#9230 Updates #3363 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
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	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	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	47002d93a3	ipn/ipnlocal: add a few metrics for PeerAPI and LocalAPI Mainly motivated by wanting to know how much Taildrop is used, but also useful when tracking down how many invalid requests are generated. Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Andrew Dunham	a887ca7efe	ipn/ipnlocal: improve redactErr to handle more cases This handles the case where the inner os.PathError is wrapped in another error type, and additionally will redact errors of type os.LinkError.
