Andrew Dunham	f0d6f173c9	net/netcheck: try ICMP if UDP is blocked (#5056 ) Signed-off-by: Andrew Dunham <andrew@du.nham.ca>	2 years ago
Brad Fitzpatrick	a12aad6b47	all: convert more code to use net/netip directly perl -i -npe 's,netaddr.IPPrefixFrom,netip.PrefixFrom,' $(git grep -l -F netaddr.) perl -i -npe 's,netaddr.IPPortFrom,netip.AddrPortFrom,' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPrefix,netip.Prefix,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPPort,netip.AddrPort,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IP\b,netip.Addr,g' $(git grep -l -F netaddr. ) perl -i -npe 's,netaddr.IPv6Raw\b,netip.AddrFrom16,g' $(git grep -l -F netaddr. ) goimports -w . Then delete some stuff from the net/netaddr shim package which is no longer neeed.

Brad Fitzpatrick	7eaf5e509f	net/netaddr: start migrating to net/netip via new netaddr adapter package Updates #5162 Change-Id: Id7bdec303b25471f69d542f8ce43805328d56c12 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
David Anderson	c1cb3efbba	net/netcheck: test for OS IPv6 support as well as connectivity. This lets us distinguish "no IPv6 because the device's ISP doesn't offer IPv6" from "IPv6 is unavailable/disabled in the OS". Signed-off-by: David Anderson <danderson@tailscale.com>	2 years ago
Josh Bleecher Snyder	0868329936	all: use any instead of interface{} My favorite part of generics. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Avery Pennarun	0d4a0bf60e	magicsock: if STUN failed to send before, rebind before STUNning again. On iOS (and possibly other platforms), sometimes our UDP socket would get stuck in a state where it was bound to an invalid interface (or no interface) after a network reconfiguration. We can detect this by actually checking the error codes from sending our STUN packets. If we completely fail to send any STUN packets, we know something is very broken. So on the next STUN attempt, let's rebind the UDP socket to try to correct any problems. This fixes a problem where iOS would sometimes get stuck using DERP instead of direct connections until the backend was restarted.

Brad Fitzpatrick	1ae35b6c59	net/{interfaces,netcheck}: rename some fields, funcs Split out of Denton's #2164, to make that diff smaller to review. This change has no behavior changes. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	c6358f2247	net/netcheck: add a few more STUN retries for prior DERP home For #1310, maybe. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	676b5b7946	net/netcheck: improve the preferred DERP hysteresis Users in Amsterdam (as one example) were flipping back and forth between equidistant London & Frankfurt relays too much. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	053a1d1340	all: annotate log verbosity levels on most egregiously spammy log prints Fixes #924 Fixes #282 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	7ac91c15bd	net/netcheck: fix tests on Windows Updates #50	4 years ago
Brad Fitzpatrick	5c6d8e3053	netcheck, tailcfg, interfaces, magicsock: survey UPnP, NAT-PMP, PCP Don't do anything with UPnP, NAT-PMP, PCP yet, but see how common they are in the wild. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	2d6e84e19e	net/netcheck, wgengine/magicsock: replace more UDPAddr with netaddr.IPPort	4 years ago
Brad Fitzpatrick	deb113838e	net/netcheck: use logger.ArgWriter in logConciseReport, fix comma bug, add tests	5 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.	5 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	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. Updates #376	5 years ago
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>	5 years ago
