Brad Fitzpatrick	93ffc565e5	derp: remove protocol version 1 support ... It hasn't existed for a long time and there are no current users. Fixes #199	4 years ago
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	f6dc47efe4	tailcfg, controlclient, magicsock: add control feature flag to enable DRPO ... Updates #150	4 years ago

Ross Zurowski	f90f35c123	Merge pull request #686 from tailscale/rosszurowski/add-region-name-to-derpmap ... derpmap: add full region name	4 years ago
Ross Zurowski	3e2bfe48c3	derpmap: add full region name ... We're beginning to reference DERP region names in the admin UI, so it's best to consolidate this information in our DERP map. Signed-off-by: Ross Zurowski <ross@rosszurowski.com>	4 years ago
Josh Bleecher Snyder	062bd67d3b	derp: use rand instead of crypto/rand to generate jitter ... We don't need crypto/rand. Let the OS keep its entropy bits. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	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
Brad Fitzpatrick	0512fd89a1	wgengine/magicsock: simplify handlePingLocked ... It's no longer true that 'de may be nil'	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
