Charlotte Brandhorst-Satzkorn	ff2b3d02e6	Fix typo in cmd/tailscale/cli/cli.go (#1069 ) Remove duplicate 'to connect' in error message. Fixes #1068 Signed-off-by: Charlotte Brandhorst-Satzkorn <charlotte@catzkorn.dev>	4 years ago
Frederik “Freso” S. Olesen	a9a80ab372	tailscaled.service: Harden systemd unit somewhat (#1062 ) While not a full capability lockdown of the systemd unit, this still improves sandboxing and security of the running process a good deal.

Brad Fitzpatrick	57dd247376	cmd/tailscaled, logpolicy, logtail: support log levels Log levels can now be specified with "[v1] " or "[v2] " substrings that are then stripped and filtered at the final logger. This follows our existing "[unexpected]" etc convention and doesn't require a wholesale reworking of our logging at the moment. cmd/tailscaled then gets a new --verbose=N flag to take a log level that controls what gets logged to stderr (and thus systemd, syslog, etc). Logtail is unaffected by --verbose. This commit doesn't add annotations to any existing log prints. That is in the next commit.

Christine Dodrill	7ea809897d	ipn/ipnserver: enable systemd-notify support Addresses #964 Still to be done: - Figure out the correct logging lines in util/systemd - Figure out if we need to slip the systemd.Status function anywhere else - Log util/systemd errors? (most of the errors are of the "you cannot do anything about this, but it might be a bad idea to crash the program if it errors" kind) Assistance in getting this over the finish line would help a lot.

Josh Bleecher Snyder	34a0292433	depaware.txt: update Upgrading staticcheck upgraded golang.org/x/sync (one downside of mixing our tools in with our regular go.mod), which introduced a new dependency via https://go-review.googlesource.com/c/sync/+/251677 That CL could and probably should be written without runtime/debug, but it's not clear to me that that is better at this moment than simply accepting the additional package as a dependency.

Josh Bleecher Snyder	aa9d7f4665	tstime: add Parse3339B, for byte slices Use go4.org/mem for memory safety. A slight performance hit, but a huge performance win for clients who start with a []byte.

Avery Pennarun	f99f6608ff	Reverse earlier "allow tag without 'tag:' prefix" changes. These accidentally make the tag syntax more flexible than was intended, which will create forward compatibility problems later. Let's go back to the old stricter parser.

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.

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).

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
