David Anderson	9cd4e65191	smallzstd: new package that constructs zstd small encoders/decoders. It's just a config wrapper that passes "use less memory at the expense of compression" parameters by default, so that we don't accidentally construct resource-hungry (de)compressors. Also includes a benchmark that measures the memory cost of the small variants vs. the stock variants. 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).

Brad Fitzpatrick	77d3ef36f4	wgengine/magicsock: hook up discovery messages, upgrade to LAN works Ping messages now go out somewhat regularly, pong replies are sent, and pong replies are now partially handled enough to upgrade off DERP to LAN. CallMeMaybe packets are sent & received over DERP, but aren't yet handled. That's next (and regular maintenance timers), and then WAN should work. Updates #483	4 years ago

Brad Fitzpatrick	e6b84f2159	all: make client use server-provided DERP map, add DERP region support Instead of hard-coding the DERP map (except for cmd/tailscale netcheck for now), get it from the control server at runtime. And make the DERP map support multiple nodes per region with clients picking the first one that's available. (The server will balance the order presented to clients for load balancing) This deletes the stunner package, merging it into the netcheck package instead, to minimize all the config hooks that would've been required. Also fix some test flakes & races.

Brad Fitzpatrick	922d9546bf	wgengine: don't allocate so much in userspaceEngine.getStatus It was one of the top garbage producers on my phone. It's slated to be deleted and replaced anyway, but this helps in the meantime. The go.sum changes look scary, but the new dep only adds 240 bytes to the binary. The go.sum noise is just cmd/go being aggressive in including a lot of stuff (which is being fixed in Go 1.15, for what I understand). And I ran a go mod tidy, which added some too. (I had to write a custom wrapper around go mod tidy because this mod tidy normally breaks on tailscale.io/control being missing but referenced in tests) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	01b4bec33f	stunner: re-do how Stunner works It used to make assumptions based on having Anycast IPs that are super near. Now we're intentionally going to a bunch of different distant IPs to measure latency. Also, optimize how the hairpin detection works. No need to STUN on that socket. Just use that separate socket for sending, once we know the other UDP4 socket's endpoint. The trick is: make our test probe also a STUN packet, so it fits through magicsock's existing STUN routing. This drops netcheck from ~5 seconds to ~250-500ms. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
