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	54e6c3a290	version: use OSS repo's version when building. When building with redo, also include the git commit hash from the proprietary repo, so that we have a precise commit that identifies all build info (including Go toolchain version). Add a top-level build script demonstrating to downstream distros how to burn the right information into builds. Adjust `tailscale version` to print commit hashes when available. Fixes #841.

Brad Fitzpatrick	86c271caba	types/logger: move RusagePrefixLog to logger package, disable by default The RusagePrefixLog is rarely useful, hasn't been useful in a long time, is rarely the measurement we need, and is pretty spammy (and syscall-heavy). Disable it by default. We can enable it when we're debugging memory.	4 years ago
Alex Brainman	f2ce64f0c6	wgengine/router: unfork winipcfg-go package, use upstream Use golang.zx2c4.com/wireguard/windows/tunnel/winipcfg instead of github.com/tailscale/winipcfg-go package. Updates #760 Signed-off-by: Alex Brainman <alex.brainman@gmail.com>	4 years ago
Brad Fitzpatrick	515866d7c6	ipn, ipnserver, cmd/tailscale: add "server mode" support on Windows This partially (but not yet fully) migrates Windows to tailscaled's StateStore storage system. This adds a new bool Pref, ForceDaemon, defined as: // ForceDaemon specifies whether a platform that normally // operates in "client mode" (that is, requires an active user // logged in with the GUI app running) should keep running after the // GUI ends and/or the user logs out. // // The only current applicable platform is Windows. This // forced Windows to go into "server mode" where Tailscale is // running even with no users logged in. This might also be // used for macOS in the future. This setting has no effect // for Linux/etc, which always operate in daemon mode. Then, when ForceDaemon becomes true, we now write use the StateStore to track which user started it in server mode, and store their prefs under that key. The ipnserver validates the connections/identities and informs that LocalBackend which userid is currently in charge. The GUI can then enable/disable server mode at runtime, without using the CLI. But the "tailscale up" CLI was also fixed, so Windows users can use authkeys or ACL tags, etc. Updates #275	4 years ago

Brad Fitzpatrick	8b94a769be	cmd/tailscaled: use the standard flag page instead of getopt Per discussion with @crawshaw. The CLI tool already used std flag anyway. If either of them, it would've made more sense for the CLI to use getopt.	4 years ago
Josh Bleecher Snyder	6e8328cba5	wgengine/tsdns: replace connections when net link changes (macOS) When the network link changes, existing UDP sockets fail immediately and permanently on macOS. The forwarder set up a single UDP conn and never changed it. As a result, any time there was a network link change, all forwarded DNS queries failed. To fix this, create a new connection when send requests fail because of network unreachability. This change is darwin-only, although extended it to other platforms should be straightforward.

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	3bdcfa7193	ipn: remove DisableDERP pref We depend on DERP for NAT traversal now[0] so disabling it entirely can't work. What we'll do instead in the future is let people specify alternate/additional DERP servers. And perhaps in the future we could also add a pref for nodes to say when they expect to never need/want to use DERP for data (but allow it for NAT traversal communication). But this isn't the right pref and it doesn't work, so delete it. Fixes #318 [0] https://tailscale.com/blog/how-nat-traversal-works/	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

Josh Bleecher Snyder	2352690bde	cmd/cloner: ensure cloner gets re-run when structs change If you change a struct and don't re-run cloner, your Cloner method might be inaccurate, leading to bad things. To prevent this, write out the struct as it is at the moment that cloner is caller, and attempt a conversion from that type. If the struct gets changed in any way, this conversion will fail. This will yield false positives: If you change a non-pointer field, you will be forced to re-run cloner, even though the actual generated code won't change. I think this is an acceptable cost: It is a minor annoyance, which will prevent real bugs. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
