Brad Fitzpatrick	d21956436a	ipn, tailcfg: change Windows subnet disabling behavior w/ WPAD ... In 1.0, subnet relays were not specially handled when WPAD+PAC was present on the network. In 1.2, on Windows, subnet relays were disabled if WPAD+PAC was present. That was what some users wanted, but not others. This makes it configurable per domain, reverting back to the 1.0 default state of them not being special. Users who want that behavior can then enable it.

Brad Fitzpatrick	450cfedeba	wgengine/magicsock: quiet an IPv6 warning in tests ... In tests, we force binding to localhost to avoid OS firewall warning dialogs. But for IPv6, we were trying (and failing) to bind to 127.0.0.1. You'd think we'd just say "localhost", but that's apparently ill defined. See https://tools.ietf.org/html/draft-ietf-dnsop-let-localhost-be-localhost and golang/go#22826. (It's bitten me in the past, but I can't remember specific bugs.) So use "::1" explicitly for "udp6", which makes the test quieter.	4 years ago
chungdaniel	e7ac9a4b90	tsweb: refactor JSONHandler to take status code from error if it is present (#905) ... This change is to make JSONHandler error handling intuitive, as before there would be two sources of HTTP status code when HTTPErrors were generated: one as the first return value of the handler function, and one nested inside the HTTPError. Previously, it took the first return value as the status code, and ignored the code inside the HTTPError. Now, it should expect the first return value to be 0 if there is an error, and it takes the status code of the HTTPError to set as the response code.

David Anderson	c48253e63b	wgengine/filter: add a method to run the packet filter without a packet. ... The goal is to move some of the shenanigans we have elsewhere into the filter package, so that all the weird things to do with poking at the filter is in a single place, behind clean APIs.

Brad Fitzpatrick	07b6ffd55c	ipn: only use Prefs, not computed stateKey, to determine server mode ... When the service was running without a client (e.g. after a reboot) and then the owner logs in and the GUI attaches, the computed state key changed to "" (driven by frontend prefs), and then it was falling out of server mode, despite the GUI-provided prefs still saying it wanted server mode. Also add some logging. And remove a scary "Access denied" from a user-visible error, making the two possible already-in-use error messages consistent with each other.	4 years ago

Brad Fitzpatrick	20a357b386	ipn, ipn/ipnserver: add IPN state for server in use, handle explicitly ... On Windows, we were previously treating a server used by different users as a fatal error, which meant the second user (upon starting Tailscale, explicitly or via Start Up programs) got an invasive error message dialog. Instead, give it its own IPN state and change the Notify.ErrMessage to be details in that state. Then the Windows GUI can be less aggresive about that happening. Also, * wait to close the IPN connection until the server ownership state changes so the GUI doesn't need to repeatedly reconnect to discover changes. * fix a bug discovered during testing: on system reboot, the ipnserver's serverModeUser was getting cleared while the state transitioned from Unknown to Running. Instead, track 'inServerMode' explicitly and remove the old accessor method which was error prone. * fix a rare bug where the client could start up and set the server mode prefs in its Start call and we wouldn't persist that to the StateStore storage's prefs start key. (Previously it was only via a prefs toggle at runtime)	4 years ago
David Anderson	437142daa5	version: calculate version info without using git tags. ... This makes it easier to integrate this version math into a submodule-ful world.

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.

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
