David Anderson	c493e5804f	wgengine/router: make v6-ness configurable in test, for consistent results. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	c86761cfd1	Remove tuntap references. We only use TUN.	4 years ago
Brad Fitzpatrick	bbb56f2303	wgengine/router: fix tests on Debian Buster as regular user on machine with IPv6	4 years ago
David Anderson	fddbcb0c7b	wgengine/router: support various degrees of broken IPv6. Gracefully skips touching the v6 NAT table on systems that don't have it, and doesn't configure IPv6 at all if IPv6 is globally disabled. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	0d80904fc2	wgengine/router: set up basic IPv6 routing/firewalling. Part of #19. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	2d0ed99672	wgengine, wgengine/router: add a bunch of (temporary?) engine creation logging Trying to debug what's slow on a user's machine. Updates #785	4 years ago
Brad Fitzpatrick	7c11f71ac5	wgengine/router: ignore errors deleting 169.254.255.255/32 route on Windows Updates #785	4 years ago
Brad Fitzpatrick	3528d28ed1	wgengine/router: move Tailscale's winipcfg additions into wgengine/router Part of unforking our winipcfg-go and using upstream (#760), move our additions into our repo. (We might upstream them later if upstream has interest) Originally these were: @apenwarr: "Add ifc.SyncAddresses() and SyncRoutes()." `609dcf2df5` @bradfitz: "winipcfg: make Interface.AddRoutes do as much as possible, return combined error" `e9f93d53f3` @bradfitz: "prevent unnecessary Interface.SyncAddresses work; normalize IPNets in deltaNets" `decb9ee8e1`	4 years ago
Brad Fitzpatrick	fd77268770	wgengine/router: enumerate all interfaces when finding Tailscale adapter by GUID Might fix it. I've spent too much time failing to reproduce the issue. This doesn't seem to make it worse, though (it still runs for me), so I'll include this and see if it helps others while I still work on a reliable way to reproduce it. Updates tailscale/corp#474	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
Christina Wen	f0e9dcdc0a	wgengine/router: restore /etc/resolv.conf after tailscale down is called This change is to restore /etc/resolv.conf after tailscale down is called. This is done by setting the dns.Manager before errors occur. Error collection is also added. Fixes #723	4 years ago
Brad Fitzpatrick	acafe9811f	wgengine/router: run netsh advfirewall less, rename, document setFirewall	4 years ago
Christina Wen	e862f90e34	wgengine/router/router_linux.go: fixed " route del failed" error (#756 ) * wgengine/router/router_linux.go: Switched `cidrDiff("addr")` and `cidrDiff("route")` order Signed-off-by: Christina Wen <christina@tailscale.com> Co-authored-by: Christina Wen <christina@tailscale.com>	4 years ago
Brad Fitzpatrick	7e9d1f7808	wgengine/router: tighten isMissingIPv6Err So it doesn't false positive if misused. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	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	a084c44afc	wgengine, wgengine/router, cmd/tailscale: force netfilter mode off on Synology For now. Get it working again so it's not stuck on 0.98. Subnet relay can come later. Updates #451 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

Mike Kramlich	6fa7a9a055	wgengine/router/router_userspace_bsd: on Mac the route program syntax expects delete not del -- this had caused router reconfig to fail in some cases. Fixes #673 Signed-off-by: Mike Kramlich <groglogic@gmail.com>	4 years ago

David Anderson	189d86cce5	wgengine/router: don't use 88 or 8888 as table/rule numbers. We originally picked those numbers somewhat at random, but with the idea that 8 is a traditionally lucky number in Chinese culture. Unfortunately, "88" is also neo-nazi shorthand language. Use 52 instead, because those are the digits above the letters "TS" (tailscale) on a qwerty keyboard, so we're unlikely to collide with other users. 5, 2 and 52 are also pleasantly culturally meaningless.

Eduardo Kienetz	5df6be9d38	Use LittleEndian for correct byte order on DNS IPs Nameserver IP 10.11.12.13 would otherwise get written to resolv.conf as 13.12.11.10, as was happening on my client. Signed-off-by: Eduardo Kienetz <eduardo@kienetz.com>	4 years ago

Brad Fitzpatrick	742b8b44a8	net/tsaddr: new package to hold Tailscale-specific IPs/ranges And update existing callers with (near) duplicated cases.	4 years ago
David Crawshaw	9258d64261	wgengine/router: do not call ifconfig up if SetRoutesFunc is set The NetworkExtension brings up the interface itself and does not have access to `ifconfig`, which the underlying BSD userspace router attempts to use when Up is called. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	4 years ago
Reinaldo de Souza	a8635784bc	wgengine: add BSD userspace router to darwin Darwin and FreeBSD are compatible enough to share the userspace router. The OSX router delegates to the BSD userspace router unless `SetRoutesFunc` is set. That preserves the mechanism that allows `ipn-go-bridge` to specify its own routing behavior. Fixes #177 Signed-off-by: Reinaldo de Souza <github@rei.nal.do>	4 years ago
David Anderson	5a32f8e181	wgengine/router: also accept exit code 254 from `ip rule del`. iproute2 3.16.0-2 from Debian Jessie (oldoldstable) doesn't return exit code 2 when deleting a non-existent IP rule. Fixes #434 Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
David Anderson	08a38f21c9	wgengine/router: don't filter subnet routing in netfilter. We have a filter in tailscaled itself now, which is more robust against weird network topologies (such as the one Docker creates). Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
Avery Pennarun	e7ae6a2e06	net/netns, wgengine/router: support Linux machines that don't have 'ip rule'. We'll use SO_BINDTODEVICE instead of fancy policy routing. This has some limitations: for example, we will route all traffic through the interface that has the main "default" (0.0.0.0/0) route, so machines that have multiple physical interfaces might have to go through DERP to get to some peers. But machines with multiple physical interfaces are very likely to have policy routing (ip rule) support anyway. So far, the only OS I know of that needs this feature is ChromeOS (crostini). Fixes #245. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	5 years ago
Avery Pennarun	f0b6ba78e8	wgengine: don't pass nil router.Config objects. These are hard for swift to decode in the iOS app. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	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. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
