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. This worked OK for single values, but stopped working when we started passing multiple values (noticed while trying out #7244). Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
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`. Behind a canDebug() check, similar to the /magicsock and /interfaces endpoints. Updates #7184 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Brad Fitzpatrick	b1248442c3	all: update to Go 1.20, use strings.CutPrefix/Suffix instead of our fork ... Updates #7123 Updates #5309 Change-Id: I90bcd87a2fb85a91834a0dd4be6e03db08438672 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Will Norris	71029cea2d	all: update copyright and license headers ... This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
James Tucker	2afa1672ac	ipn/ipnlocal: disallow unsigned peers from WoL ... Unsigned peers should not be allowed to generate Wake-on-Lan packets, only access Funnel. Updates #6934 Updates #7515 Updates #6475 Signed-off-by: James Tucker <james@tailscale.com>	2 years ago
Joe Tsai	bd2995c14b	ipn/ipnlocal: simplify redactErr (#6716) ... Use multierr.Range to iterate through an error tree instead of multiple invocations of errors.As. This scales better as we add more Go error types to the switch. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago
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. Finally, add tests to verify that redaction works.

Mihai Parparita	978d6af91a	ipn/ipnlocal: tweak error handling in interfaces PeerAPI debug endpoint ...

Brad Fitzpatrick	5bdca747b7	ipn/ipnlocal: fix netstack peerapi crash over IPv6 ... The peerapi IPv6 listener has a nil listener. But we didn't need the listener's address anyway, so don't try to use it. Change-Id: I8e8a1a895046d129a3683973e732d9bed82f3b02 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	b68d008fee	envknob: add CanTaildrop (TS_DISABLE_TAILDROP) to disable taildrop on device ... This matches CanSSHD (TS_DISABLE_SSH_SERVER) for administratively disabling the code on a node, regardless of local or server configs. This can be configured in /etc/default/tailscaled on Linux, %ProgramData%\Tailscale\tailscaled-env.txt on Windows, or /etc/tailscale/tailscaled-env.txt on Synology. (see getPlatformEnvFile) Also delete some dead code and tidy up some docs. Change-Id: I79a87c03e33209619466ea8aeb0f6651afcb8789 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Brad Fitzpatrick	4a82b317b7	ipn/{ipnlocal,localapi}: use strs.CutPrefix, add more domain validation ... The GitHub CodeQL scanner flagged the localapi's cert domain usage as a problem because user input in the URL made it to disk stat checks. The domain is validated against the ipnstate.Status later, and only authenticated root/configured users can hit this, but add some paranoia anyway.

Brad Fitzpatrick	1b89662eff	ipn/ipnlocal: make peerapi listener on Android avoid the kernel ... We intercept the peerapi port in netstack anyway, so there's no reason the linux kernel on Android needs to know about it. It's only getting in the way and causing problems for reasons we don't fully understand. But we don't even need to understand it because it's not relevant anymore. Instead, provide a dummy net.Listener that just sits and blocks to pacify the rest of the code that assumes it can be stuck in a Listener.Accept call and call Listener.Close and Listener.Addr. We'll likely do this for all platforms in the future, if/when we also link in netstack on iOS.

Brad Fitzpatrick	e96dd00652	ipn/ipnlocal: add capability for debugging peers over peerapi ... The default is still users can debug their own nodes.

Brad Fitzpatrick	bb94561c96	net/netutil: fix regression where peerapi would get closed after 1st req ... I introduced a bug in 8fe503057d when unifying oneConnListener implementations. The NewOneConnListenerFrom API was easy to misuse (its Close method closes the underlying Listener), and we did (via http.Serve, which closes the listener after use, which meant we were close the peerapi's listener, even though we only wanted its Addr) Instead, combine those two constructors into one and pass in the Addr explicitly, without delegating through to any Listener.

Brad Fitzpatrick	bd90781b34	ipn/ipnlocal, wgengine/netstack: use netstack for peerapi server ... We're finding a bunch of host operating systems/firewalls interact poorly with peerapi. We either get ICMP errors from the host or users need to run commands to allow the peerapi port: https://github.com/tailscale/tailscale/issues/3842#issuecomment-1025133727 ... even though the peerapi should be an internal implementation detail. Rather than fight the host OS & firewalls, this change handles the server side of peerapi entirely in netstack (except on iOS), so it never makes its way to the host OS where it might be messed with. Two main downsides are: 1) netstack isn't as fast, but we don't really need speed for peerapi. And actually, with fewer trips to/from the kernel, we might actually make up for some of the netstack performance loss by staying in userspace. 2) tcpdump / Wireshark etc packet captures will no longer see the peerapi traffic. Oh well. Crawshaw's been wanting to add packet capture server support to tailscaled, so we'll probably do that sooner now. A future change might also then use peerapi for the client-side (except on iOS).
