David Anderson	e7eb46bced	wgengine/magicsock: add an explicit else branch to peerMap update. Clarifies that the replace+delete of peerinfo data is only when peerInfo already exists. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	1c56643136	disco: amplify comment that disco ping's NodeKey shouldn't be trusted by itself. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Brad Fitzpatrick	75a7779b42	disco, wgengine/magicsock: send self node key in disco pings This lets clients quickly (sub-millisecond within a local LAN) map from an ambiguous disco key to a node key without waiting for a CallMeMaybe (over relatively high latency DERP). Updates #3088 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	dabeda21e0	net/tstun: block looped disco traffic Updates #1526 (maybe fixes? time will tell) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Josh Bleecher Snyder	25df067dd0	all: adapt to opaque netaddr types This commit is a mishmash of automated edits using gofmt: gofmt -r 'netaddr.IPPort{IP: a, Port: b} -> netaddr.IPPortFrom(a, b)' -w . gofmt -r 'netaddr.IPPrefix{IP: a, Port: b} -> netaddr.IPPrefixFrom(a, b)' -w . gofmt -r 'a.IP.Is4 -> a.IP().Is4' -w . gofmt -r 'a.IP.As16 -> a.IP().As16' -w . gofmt -r 'a.IP.Is6 -> a.IP().Is6' -w . gofmt -r 'a.IP.As4 -> a.IP().As4' -w . gofmt -r 'a.IP.String -> a.IP().String' -w . And regexps: \w(.)\.Port = (.) -> $1 = $1.WithPort($2) \w(.)\.IP = (.) -> $1 = $1.WithIP($2) And lots of manual fixups. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Brad Fitzpatrick	edf64e0901	wgengine/magicsock: send, use endpoints in CallMeMaybe messages Fixes #1172 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	b5b4992eff	disco: support parsing/encoding endpoints in call-me-maybe frames Updates #1172 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	a6559a8924	wgengine/magicsock: run test DERP in mode where only disco packets allowed So we don't accidentally pass a NAT traversal test by having DERP pick up our slack when we really just wanted DERP as an OOB messaging channel.	4 years ago
Brad Fitzpatrick	f5f3885b5b	wgengine/magicsock: bunch of misc discovery path cleanups * fix tailscale status for peers using discovery * as part of that, pull out disco address selection into reusable and testable discoEndpoint.addrForSendLocked * truncate ping/pong logged hex txids in half to eliminate noise * move a bunch of random time constants into named constants with docs * track a history of per-endpoint pong replies for future use & status display * add "send" and " got" prefix to discovery message logging immediately before the frame type so it's easier to read than searching for the "<-" or "->" arrows earlier in the line; but keep those as the more reasily machine readable part for later. Updates #483	4 years ago
Brad Fitzpatrick	847b6f039b	disco: simplify expression, appease staticcheck Was: disco/disco.go:164:10: unnecessary use of fmt.Sprintf (S1039)	4 years ago
Brad Fitzpatrick	0f0ed3dca0	wgengine/magicsock: clean up discovery logging Updates #483	4 years ago
Brad Fitzpatrick	77d3ef36f4	wgengine/magicsock: hook up discovery messages, upgrade to LAN works Ping messages now go out somewhat regularly, pong replies are sent, and pong replies are now partially handled enough to upgrade off DERP to LAN. CallMeMaybe packets are sent & received over DERP, but aren't yet handled. That's next (and regular maintenance timers), and then WAN should work. Updates #483	4 years ago
Brad Fitzpatrick	eb4eb34f37	disco: new package for parsing & marshaling discovery messages Updates #483	4 years ago
