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>	3 years ago

David Anderson	19eca34f47	wgengine/router: fix FreeBSD configuration failure on the v6 /48. On FreeBSD, we add the interface IP as a /48 to work around a kernel bug, so we mustn't then try to add a /48 route to the Tailscale ULA, since that will fail as a dupe.

David Anderson	27a1a2976a	wgengine/router: add a CallbackRouter shim. The shim implements both network and DNS configurators, and feeds both into a single callback that receives both configs. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	6ad44f9fdf	wgengine: take in dns.Config, split out to resolver.Config and dns.OSConfig. Stepping stone towards having the DNS package handle the config splitting. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

Denton Gentry	04e72f95cc	wgengine/router: add OpenBSD IPv6 support. Similar to FreeBSD in https://github.com/tailscale/tailscale/issues/1307, add IPv6 addresses with a prefix length of 48. Fixes https://github.com/tailscale/tailscale/issues/1372 Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
Denton Gentry	bcea88da46	wgengine: support FreeBSD with IPv6. Fixes https://github.com/tailscale/tailscale/issues/1307 for keepsies. We cannot set the tun interface address as a /128 on FreeBSD, due to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218508 Instead we set the interface address as a /48, which is enabled by commit `82edf94df7`.

Denton Gentry	061422affc	freebsd: ignore IPv6 for now FreeBSD tun devices don't work with the way we implement IPv6 https://github.com/tailscale/tailscale/issues/1307 At least for now, remove any IPv6 addresses from the netmap. Signed-off-by: Denton Gentry <dgentry@tailscale.com>	3 years ago
David Anderson	1cb0ffc3ff	wgengine/router: make windows gracefully handle disabled IPv4 or IPv6. This is necessary because either protocol can be disabled globally by a Windows registry policy, at which point trying to touch that address family results in "Element not found" errors. This change skips programming address families that Windows tell us are unavailable. Fixes #1396. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	8d77dfdacb	wgengine/router: add a dummy IPv6 address if needed for default routing. Fixes #1339 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

Brad Fitzpatrick	2d96215d97	wgengine/router: make Linux delRoute idempotent, cidrDiff fail late as possible This makes cidrDiff do as much as possible before failing, and makes a delete of an already-deleted rule be a no-op. We should never do this ourselves, but other things on the system can, and this should help us recover a bit. Also adds the start of root-requiring tests. TODO: hook into wgengine/monitor and notice when routes are changed behind our back, and invalidate our routes map and re-read from kernel (via the ip command) at least on the next reconfig call.

Brad Fitzpatrick	d76334d2f0	ipn: split LocalBackend off into new ipn/ipnlocal package And move a couple other types down into leafier packages. Now cmd/tailscale doesn't bring in netlink, magicsock, wgengine, etc. Fixes #1181 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	a2aa6cd2ed	wgengine/router: clarify disabled IPv6 message on Linux	3 years ago
David Anderson	267531e4f8	wgengine/router: probe better for v6 policy routing support. Previously we disabled v6 support if the disable_policy knob was missing in /proc, but some kernels support policy routing without exposing the toggle. So instead, treat disable_policy absence as a "maybe", and make the direct `ip -6 rule` probing a bit more elaborate to compensate. Fixes #1241.

Brad Fitzpatrick	c7fc4a06da	wgengine/router: don't configure IPv6 on Linux when IPv6 is unavailable Fixes #1214 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	4fea604979	wgengine/router: stop setPrivateNetwork goroutine on configureInterface failure On Windows, configureInterface starts a goroutine reconfiguring the Windows firewall. But if configureInterface fails later, that goroutine kept running and likely failing forever, spamming logs. Make it stop quietly if its launching goroutine filed.	3 years ago
Alex Brainman	6e4231c03c	wgengine/router/dns: remove unused code Commit 68ddf1 removed code that reads `SOFTWARE\Tailscale IPN\SearchList` registry value. But the commit left code that writes that value. So now this package writes and never reads the value. Remove the code to stop pointless work. Updates #853 Signed-off-by: Alex Brainman <alex.brainman@gmail.com>	4 years ago
Brad Fitzpatrick	0d94fe5f69	wgengine/router: disable IPv6 on Linux if ip rule -6 fails (#1074 ) Updates #562 Fixes #973 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago
