Andrew Dunham	73fa7dd7af	util/slicesx: add package for generic slice functions, use Now that we're using rand.Shuffle in a few locations, create a generic shuffle function and use it instead. While we're at it, move the interleaveSlices function to the same package for use. Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: I0b00920e5b3eea846b6cedc30bd34d978a049fd3	3 years ago

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.

Denton Gentry	51288221ce	cmd/tailscale: use request Schema+Host for QNAP authLogin.cgi QNAP allows users to set the port number for the management WebUI, which includes authLogin.cgi. If they do, then connecting to localhost:8080 fails. https://github.com/tailscale/tailscale-qpkg/issues/74#issuecomment-1407486911 Fixes https://github.com/tailscale/tailscale/issues/7108 Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
Aaron Klotz	f18beaa1e4	cmd/mkmanifest, cmd/tailscale, cmd/tailscaled: remove Windows arm32 resources from OSS Given recent changes in corp, I originally thought we could remove all of the syso files, but then I realized that we still need them so that binaries built purely from OSS (without going through corp) will still receive a manifest. We can remove the arm32 one though, since we don't support 32-bit ARM on Windows. Updates https://github.com/tailscale/corp/issues/9576 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	3 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.

Andrew Dunham	2755f3843c	health, net/tlsdial: add healthcheck for self-signed cert When we make a connection to a server, we previously would verify with the system roots, and then fall back to verifying with our baked-in Let's Encrypt root if the system root cert verification failed. We now explicitly check for, and log a health error on, self-signed certificates. Additionally, we now always verify against our baked-in Let's Encrypt root certificate and log an error if that isn't successful. We don't consider this a health failure, since if we ever change our server certificate issuer in the future older non-updated versions of Tailscale will no longer be healthy despite being able to connect.

Brad Fitzpatrick	ba5aa2c486	version, cmd/tailscale: add version.Meta, tailscale version --json Add `tailscale version --json` JSON output mode. This will be used later for a double-opt-in (per node consent like Tailscale SSH + control config) to let admins do remote upgrades via `tailscale update` via a c2n call, which would then need to verify the cmd/tailscale found on disk for running tailscale update corresponds to the running tailscaled, refusing if anything looks amiss. Plus JSON output modes are just nice to have, rather than parsing unstable/fragile/obscure text formats.

Denton Gentry	a200a23f97	Revert "cmd/tailscale: access QNAP via localhost" When running `tailscale web` as a standalone process, it was necessary to send auth requests to QTS using localhost to avoid hitting the proxy recursively. However running `tailscale web` as a process means it is consuming RAM all the time even when it isn't actively doing anything. After switching back to the `tailscale web` CGI mode, we don't need to specifically use localhost for QNAP auth. This reverts commit `e0cadc5496`.

Maisem Ali	235309adc4	all: store NL keys per profile This moves the NetworkLock key from a dedicated StateKey to be part of the persist.Persist struct. This struct is stored as part for ipn.Prefs and is also the place where we store the NodeKey. It also moves the ChonkDir from "/tka" to "/tka-profile/<profile-id>". The rename was intentional to be able to delete the "/tka" dir if it exists. This means that we will have a unique key per profile, and a unique directory per profile. Note: `tailscale logout` will delete the entire profile, including any keys. It currently does not delete the ChonkDir. Signed-off-by: Maisem Ali <maisem@tailscale.com>	3 years ago

Brad Fitzpatrick	88c2afd1e3	ipn/ipnlocal, net/dns, util/cloudenv: specialize DNS config on Google Cloud This does three things: If you're on GCP, it adds a .internal DNS split route to the metadata server, so we never break GCP DNS names. This lets people have some Tailscale nodes on GCP and some not (e.g. laptops at home) without having to add a Tailnet-wide .internal DNS route. If you already have such a route, though, it won't overwrite it. * If the 100.100.100.100 DNS forwarder has nowhere to forward to, it forwards it to the GCP metadata IP, which forwards to 8.8.8.8. This means there are never errNoUpstreams ("upstream nameservers not set") errors on GCP due to e.g. mangled /etc/resolv.conf (GCP default VMs don't have systemd-resolved, so it's likely a DNS supremacy fight) * makes the DNS fallback mechanism use the GCP metadata IP as a fallback before our hosted HTTP-based fallbacks I created a default GCP VM from their web wizard. It has no systemd-resolved. I then made its /etc/resolv.conf be empty and deleted its GCP hostnames in /etc/hosts. I then logged in to a tailnet with no global DNS settings. With this, tailscaled writes /etc/resolv.conf (direct mode, as no systemd-resolved) and sets it to 100.100.100.100, which then has regular DNS via the metadata IP and .internal DNS via the metadata IP as well. If the tailnet configures explicit DNS servers, those are used instead, except for .internal. This also adds a new util/cloudenv package based on version/distro where the cloud type is only detected once. We'll likely expand it in the future for other clouds, doing variants of this change for other popular cloud environments.

Aaron Klotz	b005b79236	net/dns, paths, util/winutil: change net/dns/windowsManager NRPT management to support more than 50 domains. AFAICT this isn't documented on MSDN, but based on the issue referenced below, NRPT rules are not working when a rule specifies > 50 domains. This patch modifies our NRPT rule generator to split the list of domains into chunks as necessary, and write a separate rule for each chunk. For compatibility reasons, we continue to use the hard-coded rule ID, but as additional rules are required, we generate new GUIDs. Those GUIDs are stored under the Tailscale registry path so that we know which rules are ours. I made some changes to winutils to add additional helper functions in support of both the code and its test: I added additional registry accessors, and also moved some token accessors from paths to util/winutil.

Brad Fitzpatrick	adc97e9c4d	cmd/tailscale: make --accept-routes default true on Windows, macOS GUI One of the most annoying parts of using the Tailscale CLI on Windows and the macOS GUI is that Tailscale's GUIs default to running with "Route All" (accept all non-exitnode subnet routes) but the CLI--being originally for Linux--uses the Linux default, which is to not accept subnets. Which means if a Windows user does, e.g.: tailscale up --advertise-exit-node Or: tailscale up --shields-up ... then it'd warn about reverting the --accept-routes option, which the user never explicitly used. Instead, make the CLI's default match the platform/GUI's default. Change-Id: I15c804b3d9b0266e9ca8651e0c09da0f96c9ef8d Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	63cd581c3f	safesocket: add ConnectionStrategy, provide control over fallbacks `fee2d9fad` added support for cmd/tailscale to connect to IPNExtension. It came in two parts: If no socket was provided, dial IPNExtension first, and also, if dialing the socket failed, fall back to IPNExtension. The second half of that support caused the integration tests to fail when run on a machine that was also running IPNExtension. The integration tests want to wait until the tailscaled instances that they spun up are listening. They do that by dialing the new instance. But when that dial failed, it was falling back to IPNExtension, so it appeared (incorrectly) that tailscaled was running. Hilarity predictably ensued. If a user (or a test) explicitly provides a socket to dial, it is a reasonable assumption that they have a specific tailscaled in mind and don't want to fall back to IPNExtension. It is certainly true of the integration tests. Instead of adding a bool to Connect, split out the notion of a connection strategy. For now, the implementation remains the same, but with the details hidden a bit. Later, we can improve that. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	39ffa16853	net/dnscache, net/tsdial: add DNS caching to tsdial UserDial This is enough to handle the DNS queries as generated by Go's net package (which our HTTP/SOCKS client uses), and the responses generated by the ExitDNS DoH server. This isn't yet suitable for putting on 100.100.100.100 where a number of different DNS clients would hit it, as this doesn't yet do EDNS0. It might work, but it's untested and likely incomplete. Likewise, this doesn't handle anything about truncation, as the exchanges are entirely in memory between Go or DoH. That would also need to be handled later, if/when it's hooked up to 100.100.100.100.

We set the ACL so that only talescaled's user (ie, LocalSystem) and the Administrators group may access our directory. We must include Administrators to ensure that logs continue to be easily accessible; omitting that group would force users to use special tools to log in interactively as LocalSystem, which is not ideal. (Note that the ACL we apply matches the ACL that was used for LocalSystem's AppData\Local). There are two cases where we need to reset perms: One is during migration from the old location to the new.

Josh Bleecher Snyder	a4e19f2233	version: remove rsc.io/goversion dependency rsc.io/goversion is really expensive. Running version.ReadExe on tailscaled on darwin allocates 47k objects, almost 11mb. All we want is the module info. For that, all we need to do is scan through the binary looking for the magic start/end strings and then grab the bytes in between them.

Denton Gentry	d2480fd508	net/netns: support !CAP_NET_ADMIN netns_linux checked whether "ip rule" could run to determine whether to use SO_MARK for network namespacing. However in Linux environments which lack CAP_NET_ADMIN, such as various container runtimes, the "ip rule" command succeeds but SO_MARK fails due to lack of permission. SO_BINDTODEVICE would work in these environments, but isn't tried. In addition to running "ip rule" check directly whether SO_MARK works or not.

Brad Fitzpatrick	5190435d6e	cmd/tailscale: rewrite the "up" checker, fix bugs The old way was way too fragile and had felt like it had more special cases than normal cases. (see #1874, #1860, #1834, etc) It became very obvious the old algorithm didn't work when we made the output be pretty and try to show the user the command they need to run in `5ecc7c7200` for #1746) The new algorithm is to map the prefs (current and new) back to flags and then compare flags. This nicely handles the OS-specific flags and the n:1 and 1:n flag:pref cases. No change in the existing already-massive test suite, except some ordering differences (the missing items are now sorted), but some new tests are added for behavior that was broken before. In particular, it now: * preserves non-pref boolean flags set to false, and preserves exit node IPs (mapping them back from the ExitNodeID pref, as well as ExitNodeIP), * doesn't ignore --advertise-exit-node when doing an EditPrefs call (#1880) * doesn't lose the --operator on the non-EditPrefs paths (e.g. with --force-reauth, or when the backend was not in state Running).

Brad Fitzpatrick	e78e26b6fb	cmd/tailscale: fix another up warning with exit nodes The --advertise-routes and --advertise-exit-node flags both mutating one pref is the gift that keeps on giving. I need to rewrite the this up warning code to first map prefs back to flag values and then just compare flags instead of comparing prefs, but this is the minimal fix for now. This also includes work on the tests, to make them easier to write (and more accurate), by letting you write the flag args directly and have that parse into the upArgs/MaskedPrefs directly, the same as the code, rather than them being possibly out of sync being written by hand.
