Brad Fitzpatrick	deb113838e	net/netcheck: use logger.ArgWriter in logConciseReport, fix comma bug, add tests	4 years ago
Brad Fitzpatrick	becce82246	net/netns, misc tests: remove TestOnlySkipPrivilegedOps, argv checks ... The netns UID check is sufficient for now. We can do something else later if/when needed.	4 years ago
Brad Fitzpatrick	7f68e097dd	net/netcheck: fix HTTPS fallback bug from earlier today ... My earlier 3fa58303d0 tried to implement the net/http.Tranhsport.DialTLSContext hook, but I didn't return a *tls.Conn, so we ended up sending a plaintext HTTP request to an HTTPS port. The response ended up being Go telling as such, not the /derp/latency-check handler's response (which is currently still a 404). But we didn't even get the 404. This happened to work well enough because Go's built-in error response was still a valid HTTP response that we can measure for timing purposes, but it's not a great answer. Notably, it means we wouldn't be able to get a future handler to run server-side and count those latency requests.	4 years ago
David Anderson	5114df415e	net/netns: set the bypass socket mark on linux. ... This allows tailscaled's own traffic to bypass Tailscale-managed routes, so that things like tailscale-provided default routes don't break tailscaled itself. Progress on #144.

Brad Fitzpatrick	9e3ad4f79f	net/netns: add package for start of network namespace support ... And plumb in netcheck STUN packets. TODO: derphttp, logs, control. Updates #144 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	0245bbe97b	Make netcheck handle v6-only interfaces better, faster. ... Also: * add -verbose flag to cmd/tailscale netcheck * remove some API from the interfaces package * convert some of the interfaces package to netaddr.IP * don't even send IPv4 probes on machines with no IPv4 (or only v4 loopback) * and once three regions have replied, stop waiting for other probes at 2x the slowest duration.

Avery Pennarun	7cd9ff3dde	net/netcheck: fix race condition initializting RegionLatency maps. ... Under some conditions, code would try to look things up in the maps before the first call to updateLatency. I don't see any reason to delay initialization of the maps, so let's just init them right away when creating the Report instance. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
