Christine Dodrill	391207bbcf	tstest/integration/vms: use one testcontrol instance per VM (#2437 ) This paves the way for future MagicDNS tests. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago

julianknodt	1bb6abc604	net/portmapper: add upnp port mapping Add in UPnP portmapping, using goupnp library in order to get the UPnP client and run the portmapping functions. This rips out anywhere where UPnP used to be in portmapping, and has a flow separate from PMP and PCP. RELNOTE=portmapper now supports UPnP mappings Fixes #682 Updates #2109 Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago
Brad Fitzpatrick	236eb4d04d	net/dns/resolver: upgrade forwarded MagicDNS queries to DoH when IP known Recognize Cloudflare, Google, Quad9 which are by far the majority of upstream DNS servers that people use. RELNOTE=MagicDNS now uses DNS-over-HTTPS when querying popular upstream resolvers, so DNS queries aren't sent in the clear over the Internet. Updates #915 (might fix it?) Updates #988 (gets us closer, if it fixes Android) Updates #74 (not yet configurable, but progress) Updates #2056 (not yet configurable, dup of #74?)

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. I'm trying to send more UDP packets and will see if that helps. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
Christine Dodrill	09e81b8ba1	tstest/integration/vms: deflake the tailscale_status test (#2427 ) This test used to try to run this only once, but this variant of the test attempts to run `tailscale status` up to 6 times in a loop with exponential backoff. This fixes the flakiness found in previous instances of this test. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago

julianknodt	9d4eddcef8	cmd/derper: add default -c arguments This adds some convenient defaults for -c, so that user-provided DERPs require less command line flags. Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago

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. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
Denton Gentry	0ae2d2b3ab	hostinfo: detect TestCase environment. Treat automated tests as their own, unique environment rather than the type of container they are running in. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago

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. We need to start with the raw escaped URL if we're doing it ourselves. Started to write a test but it got invasive. Will have to add those tests later in a commit that's not being cherry-picked to a release branch. Fixes #2288 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Josh Bleecher Snyder	4f4dae32dd	wgengine/magicsock: fix latent data race in test logBufWriter had no serialization. It just so happens that none of its users currently ever log concurrently. Make it safe for concurrent use. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
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
julianknodt	fb06ad19e7	wgcfg: Switch to using mem.RO As Brad suggested, mem.RO allows for a lot of easy perf gains.

Christine Dodrill	33cacb5284	tstest/integration/vms: unbreak nixos builds (#2372 ) To avoid the generated nixos disk images from becoming immune from the GC, I delete the symlink to the nix store at the end of tests. `t.Cleanup` runs at the end of a test. I changed this part of the code to have a separate timer for how long it takes to run NixOS builds, but I did that by using a subtest. This means that it was creating the NixOS image, deleting its symlink and then trying to use that symlink to find the resulting disk image, making the whole thing ineffectual. This was a mistake. I am reverting this change made in https://github.com/tailscale/tailscale/pull/2360 to remove this layer of subtesting. Signed-off-by: Christine Dodrill <xe@tailscale.com>	3 years ago
