Brad Fitzpatrick	a729070252	net/tstun: add start of Linux TAP support, with DHCP+ARP server ... Still very much a prototype (hard-coded IPs, etc) but should be non-invasive enough to submit at this point and iterate from here. Updates #2589 Co-Author: David Crawshaw <crawshaw@tailscale.com> Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	fdc081c291	net/portmapper: fix UPnP probing, work against all ports ... Prior to Tailscale 1.12 it detected UPnP on any port. Starting with Tailscale 1.11.x, it stopped detecting UPnP on all ports. Then start plumbing its discovered Location header port number to the code that was assuming port 5000.

Aaron Bieber	c179b9b535	cmd/tsshd: switch from github.com/kr/pty to github.com/creack/pty ...

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
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.

Christine Dodrill	622dc7b093	tstest/integration/vms: download images from s3 (#2035) ... This makes integration tests pull pristine VM images from Amazon S3 if they don't exist on disk. If the S3 fetch fails, it will fall back to grabbing the image from the public internet. The VM images on the public internet are known to be updated without warning and thusly change their SHA256 checksum. This is not ideal for a test that we want to be able to fire and forget, then run reliably for a very long time. This requires an AWS profile to be configured at the default path. The S3 bucket is rigged so that the requester pays. The VM images are currently about 6.9 gigabytes. Please keep this in mind when running these tests on your machine. Documentation was added to the integration test folder to aid others in running these tests on their machine. Some wording in the logs of the tests was altered.

Christine Dodrill	14c1113d2b	tstest/integration/vms: copy locally built binaries (#2006) ... Instead of pulling packages from pkgs.tailscale.com, we should use the tailscale binaries that are local to this git commit. This exposes a bit of the integration testing stack in order to copy the binaries correctly. This commit also bumps our version of github.com/pkg/sftp to the latest commit.

Josh Bleecher Snyder	1ece91cede	go.mod: upgrade wireguard-windows, de-fork wireguard-go ... Pull in the latest version of wireguard-windows. Switch to upstream wireguard-go. This requires reverting all of our import paths. Unfortunately, this has to happen at the same time. The wireguard-go change is very low risk, as that commit matches our fork almost exactly. (The only changes are import paths, CI files, and a go.mod entry.) So if there are issues as a result of this commit, the first place to look is wireguard-windows changes.

Josh Bleecher Snyder	b3ceca1dd7	wgengine/...: split into multiple receive functions ... Upstream wireguard-go has changed its receive model. NewDevice now accepts a conn.Bind interface. The conn.Bind is stateless; magicsock.Conns are stateful. To work around this, we add a connBind type that supports cheap teardown and bring-up, backed by a Conn. The new conn.Bind allows us to specify a set of receive functions, rather than having to shoehorn everything into ReceiveIPv4 and ReceiveIPv6. This lets us plumbing DERP messages directly into wireguard-go, instead of having to mux them via ReceiveIPv4. One consequence of the new conn.Bind layer is that closing the wireguard-go device is now indistinguishable from the routine bring-up and tear-down normally experienced by a conn.Bind. We thus have to explicitly close the magicsock.Conn when the close the wireguard-go device. One downside of this change is that we are reliant on wireguard-go to call receiveDERP to process DERP messages. This is fine for now, but is perhaps something we should fix in the future.

Adrian Dewhurst	04dd6d1dae	control/controlclient: sign RegisterRequest (#1549) ... control/controlclient: sign RegisterRequest Some customers wish to verify eligibility for devices to join their tailnets using machine identity certificates. TLS client certs could potentially fulfill this role but the initial customer for this feature has technical requirements that prevent their use. Instead, the certificate is loaded from the Windows local machine certificate store and uses its RSA public key to sign the RegisterRequest message. There is room to improve the flexibility of this feature in future and it is currently only tested on Windows (although Darwin theoretically works too), but this offers a reasonable starting place for now.

Josh Bleecher Snyder	aa9d7f4665	tstime: add Parse3339B, for byte slices ... Use go4.org/mem for memory safety. A slight performance hit, but a huge performance win for clients who start with a []byte. The perf hit is due largely to the MapHash call, which adds ~25ns.

chungdaniel	e7ac9a4b90	tsweb: refactor JSONHandler to take status code from error if it is present (#905) ... This change is to make JSONHandler error handling intuitive, as before there would be two sources of HTTP status code when HTTPErrors were generated: one as the first return value of the handler function, and one nested inside the HTTPError. Previously, it took the first return value as the status code, and ignored the code inside the HTTPError. Now, it should expect the first return value to be 0 if there is an error, and it takes the status code of the HTTPError to set as the response code.

The savings are significant on both compressors (~8x less memory) and decompressors (~1.4x less, not including the savings from the significantly smaller window on the compression side - with those savings included it's more like ~140x smaller).

And make the DERP map support multiple nodes per region with clients picking the first one that's available.
