Brad Fitzpatrick	16a9cfe2f4	wgengine: configure wireguard peers lazily, as needed wireguard-go uses 3 goroutines per peer (with reasonably large stacks & buffers). Rather than tell wireguard-go about all our peers, only tell it about peers we're actively communicating with. That means we need hooks into magicsock's packet receiving path and tstun's packet sending path to lazily create a wireguard peer on demand from the network map. This frees up lots of memory for iOS (where we have almost nothing left for larger domains with many users). We should ideally do this in wireguard-go itself one day, but that'd be a pretty big change. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	a89d610a3d	wgengine/tstun: move sync.Pool to package global sync.Pools should almost always be packate globals, even though in this case we only have exactly 1 TUN device anyway, so it matters less. Still, it's unusual to see a Pool that's not a package global, so move it.	4 years ago

Brad Fitzpatrick	05a79d79ae	control/controlclient: rewrite, test NetworkMap.ConciseDiffFrom It stood out a lot in hello.ipn.dev's profiles for generating a lot of garbage (and thus GC CPU).	4 years ago

Brad Fitzpatrick	2545575dd5	cmd/tailscale: default to not reporting daemon version That's what I meant to do when I added "tailscale version" but apparently I didn't.	4 years ago
David Anderson	189d86cce5	wgengine/router: don't use 88 or 8888 as table/rule numbers. We originally picked those numbers somewhat at random, but with the idea that 8 is a traditionally lucky number in Chinese culture. Unfortunately, "88" is also neo-nazi shorthand language. Use 52 instead, because those are the digits above the letters "TS" (tailscale) on a qwerty keyboard, so we're unlikely to collide with other users. 5, 2 and 52 are also pleasantly culturally meaningless.

Eduardo Kienetz	5df6be9d38	Use LittleEndian for correct byte order on DNS IPs Nameserver IP 10.11.12.13 would otherwise get written to resolv.conf as 13.12.11.10, as was happening on my client. Signed-off-by: Eduardo Kienetz <eduardo@kienetz.com>	4 years ago

Brad Fitzpatrick	a6559a8924	wgengine/magicsock: run test DERP in mode where only disco packets allowed So we don't accidentally pass a NAT traversal test by having DERP pick up our slack when we really just wanted DERP as an OOB messaging channel.	4 years ago

Dmytro Shynkevych	f3e2b65637	wgengine/magicsock: time.Sleep -> time.After Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Dmytro Shynkevych	380ee76d00	wgengine/magicsock: make time.Sleep in runDerpReader respect cancellation. Before this patch, the 250ms sleep would not be interrupted by context cancellation, which would result in the goroutine sometimes lingering in tests (100ms grace period). Signed-off-by: Dmytro Shynkevych <dmytro@tailscale.com>	4 years ago
Dmytro Shynkevych	891898525c	wgengine/magicsock: make receive from didCopy respect cancellation. Very rarely, cancellation occurs between a successful send on derpRecvCh and a call to copyBuf on the receiving side. Without this patch, this situation results in <-copyBuf blocking indefinitely.

Brad Fitzpatrick	a2267aae99	wgengine: only launch pingers for peers predating the discovery protocol Peers advertising a discovery key know how to speak the discovery protocol and do their own heartbeats to get through NATs and keep NATs open.

David Anderson	45578b47f3	tstest/natlab: refactor PacketHandler into a larger interface. The new interface lets implementors more precisely distinguish local traffic from forwarded traffic, and applies different forwarding logic within Machines for each type. This allows Machines to be packet forwarders, which didn't quite work with the implementation of Inject. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
