Brad Fitzpatrick	551e1e99e9	net/netns: don't bind to device for localhost connections Fixes derphttp test failures on Windows (for #50).	4 years ago
Alex Brainman	f2ce64f0c6	wgengine/router: unfork winipcfg-go package, use upstream Use golang.zx2c4.com/wireguard/windows/tunnel/winipcfg instead of github.com/tailscale/winipcfg-go package. Updates #760 Signed-off-by: Alex Brainman <alex.brainman@gmail.com>	4 years ago
Brad Fitzpatrick	6ee219a25d	ipn, wgengine, magicsock, tsdns: be quieter and less aggressive when offline If no interfaces are up, calm down and stop spamming so much. It was noticed as especially bad on Windows, but probably was bad everywhere. I just have the best network conditions testing on a Windows VM. Updates #604	4 years ago
Brad Fitzpatrick	587bdc4280	ipn, wgengine: disable subnet routes if network has PAC configuration Not configurable yet. Updates tailscale/corp#653 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	ed5d5f920f	net/interfaces: add interfaces.State.String method	4 years ago
Brad Fitzpatrick	cab3eb995f	net/interfaces: quiet PAC detection logging in no-PAC case, add benchmark	4 years ago
Brad Fitzpatrick	8051ecff55	net/interfaces: add State.PAC field, populate it on Windows Not used for anything yet (except logging), but populate the current proxy autoconfig PAC URL in Interfaces.State. A future change will do things based on it.	4 years ago
Brad Fitzpatrick	8893c2ee78	net/interfaces, net/netns: move default route interface code to interfaces To populate interfaces.State.DefaultRouteInterface. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	fda9dc8815	net/netns: document Windows socket binding a bit more Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	963b927d5b	net/tshttpproxy: appease staticcheck	4 years ago
Brad Fitzpatrick	5bcac4eaac	net/tshttpproxy: add GetProxyForURL negative cache Otherwise when PAC server is down, we log, and each log entry is a new HTTP request (from logtail) and a new GetProxyForURL call, which again logs, non-stop. This is also nicer to the WinHTTP service. Then also hook up link change notifications to the cache to reset it if there's a chance the network might work sooner.	4 years ago
David Anderson	8f5b52e571	net/netns: add windows support. Also remove rebinding logic from the windows router. Magicsock will instead rebind based on link change signals. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	40e12c17ec	net/netcheck: remove mistaken double Mutex.Unlock in error path Thanks to @dotaheor for noticing. Fixes #751	4 years ago
Brad Fitzpatrick	f65eb4e5c1	net/netstat: start of new netstat package, with Windows for now This will be used in a future change to do localhost connection authentication. This lets us quickly map a localhost TCP connection to a PID. (A future change will then map a pid to a user) TODO: pull portlist's netstat code into this package. Then portlist will be fast on Windows without requiring shelling out to netstat.exe.	4 years ago
Brad Fitzpatrick	9c25968b63	net/tshttpproxy: fix typo in Windows code added at least second I ran tests & vet & staticcheck, but for Linux, not Windows. (#728 would be nice)	4 years ago
Brad Fitzpatrick	b026a638c7	net/tshttpproxy: if winhttp.GetProxyForURL blocks too long, use previous value We currently have a chickend-and-egg situation in some environments where we can set up routes that WinHTTP's WPAD/PAC resolution service needs to download the PAC file to evaluate GetProxyForURL, but the PAC file is behind a route for which we need to call GetProxyForURL to e.g. dial a DERP server. As a short-term fix, just assume that the most recently returned proxy is good enough for such situations.	4 years ago
Brad Fitzpatrick	74ee374667	net/tshttpproxy: add more winhttp logging Notably around duration of calls.	4 years ago
Brad Fitzpatrick	1e0be5a458	tshttp, derphttp: send Proxy-Authorization, not Authorization, to proxies Whoops. But weirdly, sending Authorization sometimes worked?	4 years ago
Brad Fitzpatrick	2bac125cad	net/tshttpproxy: move the TS_DEBUG_FAKE_PROXY_AUTH knob up a level	4 years ago
Brad Fitzpatrick	28f9cd06f5	tshttpproxy, controlclient, derphttp, logpolicy: send Negotiate auth to proxies For Windows only, and only when built with Tailscale's Go tree. Updates tailscale/corp#583	4 years ago
Brad Fitzpatrick	f915ab6552	net/tshttpproxy: add start of Kerberos Negotiate auth to proxies on Windows For now only used by a new cmd/tailscale debug --get-url subcommand. Not yet wired up to the places making HTTP requests. Updates tailscale/corp#583	4 years ago

Brad Fitzpatrick	1e562886f5	net/netcheck: in verbose mode, probe all regions So 'tailscale netcheck --verbose' shows all regions' latencies.	4 years ago
Brad Fitzpatrick	c5eb57f4d6	net/tshttpproxy: new package, support WPAD/PAC proxies on Windows Updates tailscale/corp#553 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Brad Fitzpatrick	b97aac1718	net/interfaces: include DefaultRouteInterface in interfaces.State And log it in wgengine on change. Changing bug in #643. Updates #643	4 years ago

Brad Fitzpatrick	25b021388b	net/netns, net/interfaces: move defaultRouteInterface, add Android fallback Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Josh Bleecher Snyder	a16a793605	net/interfaces: use syscalls to find private gateway IP address iOS doesn't let you run subprocesses, which means we can't use netstat to get routing information. Instead, use syscalls and grub around in the results. We keep the old netstat version around, both for use in non-cgo builds, and for use testing the syscall-based version. Note that iOS doesn't ship route.h, so we include a copy here from the macOS 10.15 SDK (which is itself unchanged from the 10.14 SDK). I have tested manually that this yields the correct gateway IP address on my own macOS and iOS devices. More coverage would be most welcome.

David Anderson	a2b4ad839b	net/netcheck: lower the hairpin check timeout to 100ms. This single check is the long pole for netcheck, and significantly slows down magicsock tests. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	25288567ec	net/netcheck: centralize all clock values in one place. This makes it easier to see how long a netcheck might take, and what the slow bits might be. Signed-off-by: David Anderson <danderson@tailscale.com>	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	32156330a8	net/interfaces: add func LikelyHomeRouterIP For discovering where we might direct NAT-PMP/PCP/UPnP queries at in the future.	4 years ago
Brad Fitzpatrick	cf74e9039e	net/netcheck: add an informative payload in the netcheck UDP helper packets Per comment from @normanr: `0a5ab533c1 (r40401954)` Updates #188	4 years ago
Brad Fitzpatrick	0a5ab533c1	net/netcheck: send dummy packet out to help airport extreme in hairpin check At least the Apple Airport Extreme doesn't allow hairpin sends from a private socket until it's seen traffic from that src IP:port to something else out on the internet. See https://github.com/tailscale/tailscale/issues/188#issuecomment-600728643 And it seems that even sending to a likely-filtered RFC 5737 documentation-only IPv4 range is enough to set up the mapping. So do that for now. In the future we might want to classify networks that do and don't require this separately. But for now help it. I've confirmed that this is enough to fix the hairpin check on Avery's home network, even using the RFC 5737 IP. Fixes #188	4 years ago
Brad Fitzpatrick	2d6e84e19e	net/netcheck, wgengine/magicsock: replace more UDPAddr with netaddr.IPPort	4 years ago
