David Anderson	2e347d1e10	tailcfg: tweak documentation for map version 11 version: bump date.	3 years ago
David Anderson	ea49b1e811	tailcfg: bump map request version for v6 + default routes. Signed-off-by: David Anderson <danderson@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
Brad Fitzpatrick	92cdb30b26	tailcfg, control/controlclient: add goroutine dump debug feature Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	f858b0d25f	wgengine/netstack: remove some v2 logging by default Even with [v2], it still logtails and takes time to format. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Naman Sood	d01c60dad5	wgengine/netstack: use system dialer to contact servers on localhost Updates #504 Updates #707 Signed-off-by: Naman Sood <mail@nsood.in>	3 years ago
Brad Fitzpatrick	7461dded88	wgengine/monitor: on unsupported platforms, use a polling implementation Not great, but lets people working on new ports get going more quickly without having to do everything up front. As the link monitor is getting used more, I felt bad having a useless implementation. Updates #815 Updates #1427 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	8a55d463c8	net/interfaces: merge darwin files for DefaultRouteInterface in sandbox DefaultRouteInterface was previously guarded by build tags such that it was only accessible to tailscaled-on-macos, but there was no reason for that. It runs fine in the sandbox and gives better default info, so merge its file into interfaces_darwin.go. Signed-off-by: Brad Fitzpatrick <bradfitz@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	b4cf837d8a	logtail: use link monitor to determine when to retry after upload failure Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	471f0c470a	wgengine/monitor: skip some macOS route updates, fix debounce regression Debound was broken way back in `5c1e443d34` and we never noticed. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	be779b3587	safesocket, ipn/ipnserver: unify peercred info, fix bug on FreeBSD etc FreeBSD wasn't able to run "tailscale up" since the recent peercred refactoring. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	f304a45481	wgengine/monitor: add skipped failing test for Darwin route message bug Updates #1416 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	0d0ec7853c	cmd/tailscaled: don't require root on darwin with --tun=userspace-networking Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	31721759f3	wgengine/monitor: don't return nil, nil in darwin monitor We used to allow that, but now it just crashes. Separately I need to figure out why it got into this path at all, which is #1416. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Christine Dodrill	b89c757817	wgengine/tsdns: explicitly reject .onion lookups Tor has a location-hidden service feature that enables users to host services from inside the Tor network. Each of these gets a unique DNS name that ends with .onion. As it stands now, if a misbehaving application somehow manages to make a .onion DNS request to our DNS server, we will forward that to the DNS server, which could leak that to malicious third parties. See the recent bug Brave had with this[1] for more context. RFC 7686 suggests that name resolution APIs and libraries MUST respond with NXDOMAIN unless they can actually handle Tor lookups. We can't handle .onion lookups, so we reject them.

Brad Fitzpatrick	c0cdca6d06	cmd/tailscaled, logtail: share link monitor from wgengine to logtail Part of overall effort to clean up, unify, use link monitoring more, and make Tailscale quieter when all networks are down. This is especially bad on macOS where we can get killed for not being polite it seems. (But we should be polite in any case) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	24fa616e73	wgengine/monitor: make Darwin monitor shut down cleanly, add test Don't use os.NewFile or (*os.File).Close on the AF_ROUTE socket. It apparently does weird things to the fd and at least doesn't seem to close it. Just use the unix package. The test doesn't actually fail reliably before the fix, though. It was an attempt. But this fixes the integration tests. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	625c413508	ipn/ipnlocal: fix another regression from link monitoring refactor Prior to `e3df29d488`, the Engine.SetLinkChangeCallback fired immediately, even if there was no change. The ipnlocal code apparently depended on that, and it broke integration tests (which live in another repo). So mimic the old behavior and call the ipnlocal callback immediately at init.

Brad Fitzpatrick	487c520109	wgengine: fix bug from earlier commit Commit `e3df29d488` introduced this bug where the interfaces-were-changed-or-not bit got lost. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
David Anderson	793cb131f0	wgengine/router: toggle killswitch when using default routes on windows. Fixes #1398. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	ac3de93d5c	tempfork/wireguard-windows/firewall: add. This is a fork of wireguard-windows's firewall package, with the firewall rules adjusted to better line up with tailscale's needs. The package was taken from commit 3cc76ed5f222ec82748ef3bd8c41d4b059e28cdb in our fork of wireguard-go. Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago

Brad Fitzpatrick	03c344333e	cmd/tailscale: remove Windows console fixing Not needed, as we don't build this as a GUI app ever. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	e3df29d488	wgengine{,/monitor}: move interface state fetching/comparing to monitor Gets it out of wgengine so the Engine isn't responsible for being a callback registration hub for it. This also removes the Engine.LinkChange method, as it's no longer necessary. The monitor tells us about changes; it doesn't seem to need any help. (Currently it was only used by Swift, but as of `14dc790137` we just do the same from Go) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	14dc790137	wgengine/monitor: make the darwin link monitor work in the sandbox too Previously tailscaled on macOS was running "/sbin/route monitor" as a child process, but child processes aren't allowed in the Network Extension / App Store sandbox. Instead, just do what "/sbin/route monitor" itself does: unix.Socket(unix.AF_ROUTE, unix.SOCK_RAW, 0) and read that. We also parse it now, but don't do anything with the parsed results yet. We will over time, as we have with Linux netlink messages over time. Currently any message is considered a signal to poll and see what changed.

Brad Fitzpatrick	dda03a911e	wgengine/monitor: change API to permit multiple independent callbakcks Currently it assumes exactly 1 registered callback. This changes it to support 0, 1, or more than 1. This is a step towards plumbing wgengine/monitor into more places (and moving some of wgengine's interface state fetching into monitor in a later step) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
