Denton Gentry	5302e4be96	net/portmapper: only print PCP/PMP if VerboseLogs Make UPnP, NAT-PMP, and PCP packet reception logs be [v1] so they will never appear on stdout and instead only go to logtail. ``` $ tailscale netcheck 2021/10/15 22:50:31 portmap: Got PMP response; IP: w.x.y.z, epoch: 1012707 2021/10/15 22:50:31 portmap: Got PCP response: epoch: 1012707 Report: * UDP: true * IPv4: yes, w.x.y.z:1511 * IPv6: no * MappingVariesByDestIP: true * HairPinning: false * PortMapping: NAT-PMP, PCP * Nearest DERP: San Francisco * DERP latency: - sfo: 5.9ms (San Francisco) - sea: 24ms (Seattle) - dfw: 45ms (Dallas) - ord: 53.7ms (Chicago) - nyc: 74.1ms (New York City) - tok: 111.1ms (Tokyo) - lhr: 139.4ms (London) - syd: 152.7ms (Sydney) - fra: 153.1ms (Frankfurt) - sin: 182.1ms (Singapore) - sao: 190.1ms (S_o Paulo) - blr: 218.6ms (Bangalore) ``` Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
David Anderson	060ba86baa	net/portmapper: ignore IGD SSDP responses from !defaultgw Now that we multicast the SSDP query, we can get IGD offers from devices other than the current device's default gateway. We don't want to accidentally bind ourselves to those. Updates #3197 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	4a65b07e34	net/portmapper: also send UPnP SSDP query to the SSDP multicast address. Fixes #3197 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
Brad Fitzpatrick	48bdffd395	net/portmapper: remove GITHUB_ACTIONS check It's now redundant. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Anderson	b49d9bc74d	net/portmapper: fix "running a test" condition. Fixes #2686. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
julianknodt	b9bd7dbc5d	net/portmapper: log upnp information This logs some basic statistics for UPnP, so that tailscale can better understand what routers are being used and how to connect to them. Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago
Brad Fitzpatrick	bdb93c5942	net/portmapper: actually test something in TestProbeIntegration And use dynamic port numbers in tests, as Linux on GitHub Actions and Windows in general have things running on these ports.

Brad Fitzpatrick	e6d4ab2dd6	net/portmapper: add start of self-contained portmapper integration tests Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
julianknodt	98d36ee18d	net/portmapper: add hook for use with prev ip PCP handles external IPs by allowing the client to specify them in the packet, which is more explicit than requiring 2 packets from PMP, so allow for future changes to add it in easily.

julianknodt	85304d7392	net/portmapper: check disable flags Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago
julianknodt	777b711d96	net/portmapper: add pcp portmapping This adds PCP portmapping, hooking into the existing PMP portmapping. Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago
julianknodt	5c98b1b8d0	net/portmapper: move pcp code to separate file This moves all the PCP code to a separate file in preparation for portmapping with PCP. Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago
Brad Fitzpatrick	fdc081c291	net/portmapper: fix UPnP probing, work against all ports Prior to Tailscale 1.12 it detected UPnP on any port. Starting with Tailscale 1.11.x, it stopped detecting UPnP on all ports. Then start plumbing its discovered Location header port number to the code that was assuming port 5000. Fixes #2109 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	68df379a7d	net/portmapper: rename ErrGatewayNotFound to ErrGatewayRange, reword text It confused & scared people. And it was just bad. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
julianknodt	1bb6abc604	net/portmapper: add upnp port mapping Add in UPnP portmapping, using goupnp library in order to get the UPnP client and run the portmapping functions. This rips out anywhere where UPnP used to be in portmapping, and has a flow separate from PMP and PCP. RELNOTE=portmapper now supports UPnP mappings Fixes #682 Updates #2109 Signed-off-by: julianknodt <julianknodt@gmail.com>	3 years ago
Brad Fitzpatrick	92077ae78c	wgengine/magicsock: make portmapping async 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	44ab0acbdb	net/portmapper, wgengine/monitor: cache gateway IP info until link changes Cuts down allocs & CPU in steady state (on regular STUN probes) when network is unchanging. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	c64bd587ae	net/portmapper: add NAT-PMP client, move port mapping service probing * move probing out of netcheck into new net/portmapper package * use PCP ANNOUNCE op codes for PCP discovery, rather than causing short-lived (sub-second) side effects with a 1-second-expiring map + delete. * track when we heard things from the router so we can be less wasteful in querying the router's port mapping services in the future * use portmapper from magicsock to map a public port Fixes #1298 Fixes #1080 Fixes #1001 Updates #864 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
