Brad Fitzpatrick	28f6552646	wgengine/router/dns: run ipconfig /registerdns async, log timing Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
Brad Fitzpatrick	01ee638cca	Change some os.IsNotExist to errors.Is(err, os.ErrNotExist) for non-os errors. os.IsNotExist doesn't unwrap errors. errors.Is does. The ioutil.ReadFile ones happened to be fine but I changed them so we're consistent with the rule: if the error comes from os, you can use os.IsNotExist, but from any other package, use errors.Is. (errors.Is always would also work, but not worth updating all the code) The motivation here was that we were logging about failure to migrate legacy relay node prefs file on startup, even though the code tried to avoid that. See golang/go#41122	4 years ago
David Anderson	68ddf134d7	wgengine/router/dns: issue ipconfig /registerdns when applying DNS settings. Amazingly, there doesn't seem to be a documented way of updating network configuration programmatically in a way that Windows takes notice of. The naturopathic remedy for this is to invoke ipconfig /registerdns, which does a variety of harmless things and also invokes the private API that tells windows to notice new adapter settings. This makes our DNS config changes stick within a few seconds of us setting them. If we're invoking a shell command anyway, why futz with the registry at all? Because netsh has no command for changing the DNS suffix list, and its commands for setting resolvers requires parsing its output and keeping track of which server is in what index. Amazingly, twiddling the registry directly is the less painful option. Fixes #853. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
Brad Fitzpatrick	508f5c3ae0	wgengine/router: fix bug where getInterfaceRoutes always returned an empty list Regression from `f2ce64f0c6 (r43710860)` Fixes #870	4 years ago
Brad Fitzpatrick	38bde61b3d	wgengine/router: make Windows firewall configuration async Updating the Windows firewall is usually reasonably fast, but sometimes blocks for 20 seconds, 4 minutes, etc. Not sure why. Until we understand that's happening, configure it in the background without blocking the normal control flow. Updates #785 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	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	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	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

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.
