Brad Fitzpatrick	6ca078c46e	cmd/derper: move 204 handler from package main to derphttp ... Updates #13038 Change-Id: I28a8284dbe49371cae0e9098205c7c5f17225b40 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 months ago
Brad Fitzpatrick	15fc6cd966	derp/derphttp: fix netcheck HTTPS probes ... The netcheck client, when no UDP is available, probes distance using HTTPS. Several problems: * It probes using /derp/latency-check. * But cmd/derper serves the handler at /derp/probe * Despite the difference, it work by accident until c8f4dfc8c0 which made netcheck's probe require a 2xx status code. * in tests, we only use derphttp.Handler, so the cmd/derper-installed mux routes aren't preesnt, so there's no probe. That breaks tests in airplane mode. netcheck.Client then reports "unexpected HTTP status 426" (Upgrade Required) This makes derp handle both /derp/probe and /derp/latency-check equivalently, and in both cmd/derper and derphttp.Handler standalone modes. I notice this when wgengine/magicsock TestActiveDiscovery was failing in airplane mode (no wifi). It still doesn't pass, but it gets further.

Will Norris	71029cea2d	all: update copyright and license headers ... This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 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).
