Brad Fitzpatrick	309c15dfdd	types/key: restore Curve25519 clamping in NewPrivate ... It was lost during a copy from wgcfg.NewPresharedKey (which doesn't clamp) instead of wgcfg.NewPrivateKey (which does). Fortunately this was only use for discovery messages (not WireGuard) and only for ephemeral process-lifetime keys.	4 years ago
Brad Fitzpatrick	e415991256	derp, derp/derphttp: remove one RTT from DERP setup ... * advertise server's DERP public key following its ServerHello * have client look for that DEPR public key in the response PeerCertificates * let client advertise it's going into a "fast start" mode if it finds it * modify server to support that fast start mode, just not sending the HTTP response header Cuts down another round trip, bringing the latency of being able to write our first DERP frame from SF to Bangalore from ~725ms (3 RTT) to ~481ms (2 RTT: TCP and TLS).

Brad Fitzpatrick	6b80bcf112	derp: remove a client round-trip waiting on serverInfo ... It just has a version number in it and it's not really needed. Instead just return it as a normal Recv message type for those that care (currently only tests). Updates #150 (in that it shares the same goal: initial DERP latency) Updates #199 (in that it removes some DERP versioning)	4 years ago

Brad Fitzpatrick	85c3d17b3c	wgengine/magicsock: use disco ping src as a candidate endpoint ... Consider: Hard NAT (A) <---> Hard NAT w/ mapped port (B) If A sends a packet to B's mapped port, A can disco ping B directly, with low latency, without DERP. But B couldn't establish a path back to A and needed to use DERP, despite already logging about A's endpoint and adding a mapping to it for other purposes (the wireguard conn.Endpoint lookup also needed it). This adds the tracking to discoEndpoint too so it'll be used for finding a path back. Fixes tailscale/corp#556 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Josh Bleecher Snyder	909c165382	derp: remove two key.Public allocations ... Reading and writing a [32]byte key to a bufio.Reader/bufio.Writer can easily by done without allocating. Do so. It is slower; on my machine, it adds about 100ns per read/write. However, the overall request takes a minimum of several µs, and it cuts allocations meaningfully, so it is probably worth it. name old time/op new time/op delta SendRecv/msgsize=10-8 9.21µs ± 9% 9.08µs ± 8% ~ (p=0.250 n=15+15) SendRecv/msgsize=100-8 6.51µs ± 9% 6.60µs ± 7% ~ (p=0.259 n=15+13) SendRecv/msgsize=1000-8 7.24µs ±13% 7.61µs ±36% ~ (p=1.000 n=11+15) SendRecv/msgsize=10000-8 19.5µs ±15% 19.9µs ±25% ~ (p=0.890 n=14+15) name old speed new speed delta SendRecv/msgsize=10-8 1.09MB/s ± 8% 1.10MB/s ± 8% ~ (p=0.286 n=15+15) SendRecv/msgsize=100-8 15.4MB/s ± 8% 15.1MB/s ± 6% ~ (p=0.129 n=15+12) SendRecv/msgsize=1000-8 139MB/s ±15% 135MB/s ±28% ~ (p=1.000 n=11+15) SendRecv/msgsize=10000-8 516MB/s ±17% 506MB/s ±21% ~ (p=0.880 n=14+15) name old alloc/op new alloc/op delta SendRecv/msgsize=10-8 170B ± 1% 108B ± 1% -36.63% (p=0.000 n=15+15) SendRecv/msgsize=100-8 265B ± 1% 203B ± 1% -23.34% (p=0.000 n=15+15) SendRecv/msgsize=1000-8 1.18kB ± 1% 1.12kB ± 0% -5.31% (p=0.000 n=14+14) SendRecv/msgsize=10000-8 18.8kB ± 2% 18.8kB ± 2% ~ (p=0.443 n=12+12) name old allocs/op new allocs/op delta SendRecv/msgsize=10-8 4.00 ± 0% 2.00 ± 0% -50.00% (p=0.000 n=15+15) SendRecv/msgsize=100-8 4.00 ± 0% 2.00 ± 0% -50.00% (p=0.000 n=15+15) SendRecv/msgsize=1000-8 4.00 ± 0% 2.00 ± 0% -50.00% (p=0.000 n=15+15) SendRecv/msgsize=10000-8 5.00 ± 0% 3.00 ± 0% -40.00% (p=0.000 n=13+14) Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	4 years ago
