Andrew Dunham	d05a572db4	net/portmapper: handle multiple UPnP discovery responses Instead of taking the first UPnP response we receive and using that to create port mappings, store all received UPnP responses, sort and deduplicate them, and then try all of them to obtain an external address. Updates #10602 Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: I783ccb1834834ee2a9ecbae2b16d801f2354302f	9 months ago
Andrew Dunham	bac4890467	net/portmapper: be smarter about selecting a UPnP device Previously, we would select the first WANIPConnection2 (and related) client from the root device, without any additional checks. However, some routers expose multiple UPnP devices in various states, and simply picking the first available one can result in attempting to perform a portmap with a device that isn't functional. Instead, mimic what the miniupnpc code does, and prefer devices that are (a) reporting as Connected, and (b) have a valid external IP address. For our use-case, we additionally prefer devices that have an external IP address that's a public address, to increase the likelihood that we can obtain a direct connection from peers. Finally, we split out fetching the root device (getUPnPRootDevice) from selecting the best service within that root device (selectBestService), and add some extensive tests for various UPnP server behaviours.

Denton Gentry	137e9f4c46	net/portmap: add test of Mikrotik Root Desc XML. Unfortunately in the test we can't reproduce the failure seen in the real system ("SOAP fault: UPnPError") Updates https://github.com/tailscale/tailscale/issues/8364 Signed-off-by: Denton Gentry <dgentry@tailscale.com>	10 months ago
Andrew Dunham	9ee173c256	net/portmapper: fall back to permanent UPnP leases if necessary Some routers don't support lease times for UPnP portmapping; let's fall back to adding a permanent lease in these cases. Additionally, add a proper end-to-end test case for the UPnP portmapping behaviour.

Andrew Dunham	3f8e8b04fd	cmd/tailscale, cmd/tailscaled: move portmapper debugging into tailscale CLI The debug flag on tailscaled isn't available in the macOS App Store build, since we don't have a tailscaled binary; move it to the 'tailscale debug' CLI that is available on all platforms instead, accessed over LocalAPI.

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
Denton Gentry	b8fe89d15f	net/portmapper: add test for Huawei router Updates https://github.com/tailscale/tailscale/issues/6320 Signed-off-by: Denton Gentry <dgentry@tailscale.com>	2 years ago
Brad Fitzpatrick	8725b14056	all: migrate more code code to net/netip directly Instead of going through the tailscale.com/net/netaddr transitional wrappers. Updates #5162 Change-Id: I3dafd1c2effa1a6caa9b7151ecf6edd1a3fda3dd Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
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
Denton Gentry	09eaba91ad	net/portmap: add a test for Sagemcom FAST3890V3. Updates https://github.com/tailscale/tailscale/issues/3557 Signed-off-by: Denton Gentry <dgentry@tailscale.com>	2 years ago
Brad Fitzpatrick	640134421e	all: update tests to use tstest.MemLogger And give MemLogger a mutex, as one caller had, which does match the logf contract better. Signed-off-by: Brad Fitzpatrick <bradfitz@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	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.
