Brad Fitzpatrick	7f7a81e5ae	cmd/tailscaled: add func to create ipnserver.Opts To unify the Windows service and non-service/non-Windows paths a bit. And provides a way to make Linux act like Windows for testing. (notably, for testing the fix to #2137) One perhaps visible change of this is that tailscaled.exe when run in cmd.exe/powershell (not as a Windows Service) no longer uses the "_daemon" autostart key. But in addition to being naturally what falls out of this change, that's also what Windows users would likely want, as otherwise the unattended mode user is ignored when the "_daemon" autostart key is specified. Notably, this would let people debug what their normally-run-as-a-service tailscaled is doing, even when they're running in Unattended Mode.

Josh Bleecher Snyder	4b1f2ae382	tstest/integration: generate deps for all platforms in deps generator We have different deps depending on the platform. If we pick a privileged platform, we'll miss some deps. If we use the union of all platforms, the integration test won't compile on some platforms, because it'll import packages that don't compile on that platform. Give in to the madness and give each platform its own deps file. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Brad Fitzpatrick	e41193ec4d	wgengine/monitor: don't spam about Linux RTM_NEWRULE events The earlier `2ba36c294b` started listening for ip rule changes and only cared about DELRULE events, buts its subscription included all rule events, including new ones, which meant we were then catching our own ip rule creations and logging about how they were unknown.

Christine Dodrill	798b0da470	tstest/integration/vms: codegen for top level tests (#2441 ) This moves the distribution definitions into a maintainable hujson file instead of just existing as constants in `distros.go`. Comments are maintained from the inline definitions. This uses jennifer[1] for hygenic source tree creation. This allows us to generate a unique top-level test for each VM run. This should hopefully help make the output of `go test` easier to read. This also separates each test out into its own top-level test so that we can better track the time that each distro takes. I really wish there was a way to have the `test_codegen.go` file _always_ run as a part of the compile process instead of having to rely on people remembering to run `go generate`, but I am limited by my tools. This will let us remove the `-distro-regex` flag and use `go test -run` to pick which distros are run. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago

Aaditya Chaudhary	4f89fe17a2	Implemented Commandline Download Speedtest (#2064 ) Added the net/speedtest package that contains code for starting up a speedtest server and a client. The speedtest command for starting a client takes in a duration for the speedtest as well as the host and port of the speedtest server to connect to. The speedtest command for starting a server takes in a host:port pair to listen on. Signed-off-by: Aaditya Chaudhary <32117362+AadityaChaudhary@users.noreply.github.com>	3 years ago
Christine Dodrill	3ebe16558c	tstest/integration/vms: attempt to send more UDP packets (#2433 ) Apparently this test was flaking because I critically misunderstood how the kernel buffers UDP packets for senders.

Denton Gentry	e28bc49e5f	netns_linux: remove special handling for tests. With netns handling localhost now, existing tests no longer need special handling. The tests set up their connections to localhost, and the connections work without fuss. Remove the special handling for tests. Also remove the hostinfo.TestCase support, since this was the only use of it. It can be added back later if really needed, but it would be better to try to make tests work without special cases.

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. Among others, this allows Microsoft Azure App Service and AWS App Runner to work. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
Denton Gentry	1896bf99d9	netns_linux: No namespace for localhost. Connections to a control server or log server on localhost, used in a number of tests, are working right now because the calls to SO_MARK in netns fail for non-root but then we ignore the failure when running in tests. Unfortunately that failure in SO_MARK also affects container environments without CAP_NET_ADMIN, breaking Tailscale connectivity. We're about to fix netns to recognize when SO_MARK doesn't work and use SO_BINDTODEVICE instead. Doing so makes tests fail, as their sockets now BINDTODEVICE of the default route and cannot connect to localhost. Add support to skip namespacing for localhost connections, which Darwin and Windows already do. This is not conditional on running within a test, if you tell tailscaled to connect to localhost it will automatically use a non-namespaced socket to do so.

Denton Gentry	d3697053c9	hostinfo: add AWS Fargate. Several other AWS services like App Run and Lightsail Containers appear to be layers atop Fargate, to the point that we cannot easily tell them apart from within the container. Contacting the metadata service would distinguish them, but doing that from inside tailscaled seems uncalled for. Just report them as Fargate.

Brad Fitzpatrick	98ad7f279c	ipn/localapi: fix inability to receive taildrop files w/ escaped names The localapi was double-unescaping: once by net/http populating the URL, and once by ourselves later.

Brad Fitzpatrick	01e159b610	ipn/ipnlocal: save prefs to disk on UpdatePrefs Regression from `6d10655dc3`, which added UpdatePrefs but didn't write it out to disk. I'd planned on adding tests to state_test.go which is why I'd earlier added `46896a9311` to prepare for making such persistence tests easier to write, but turns out state_test.go didn't even test UpdatePrefs, so I'm staying out of there. Instead, this is tested using integration tests. Fixes #2321 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
