David Crawshaw	6b9f8208f4	net/dns: do not run wsl.exe as LocalSystem It doesn't work. It needs to run as the user. https://github.com/microsoft/WSL/issues/4803 The mechanism for doing this was extracted from: https://web.archive.org/web/20101009012531/http://blogs.msdn.com/b/winsdk/archive/2009/07/14/launching-an-interactive-process-from-windows-service-in-windows-vista-and-later.aspx While here, we also reclaculate WSL distro set on SetDNS. This accounts for: 1. potential inability to access wsl.exe on startup 2. WSL being installed while Tailscale is running 3. A new WSL distrobution being installed Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	3 years ago

David Anderson	d7f6ef3a79	util/dnsname: add a benchmark for ToFQDN. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	caaefa00a0	util/dnsname: don't validate the contents of DNS labels. DNS names consist of labels, but outside of length limits, DNS itself permits any content within the labels. Some records require labels to conform to hostname limitations (which is what we implemented before), but not all. Fixes #2024. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago

Josh Bleecher Snyder	635e4c7435	wgengine/magicsock: increase legacy ping timeout again I based my estimation of the required timeout based on locally observed behavior. But CI machines are worse than my local machine. 16s was enough to reduce flakiness but not eliminate it. Bump it up again. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

UI clients can use these names directly, rather than computing them independently.	4 years ago

Brad Fitzpatrick	5efb0a8bca	cmd/tailscale: change formatting of "tailscale status" * show DNS name over hostname, removing domain's common MagicDNS suffix. only show hostname if there's no DNS name. but still show shared devices' MagicDNS FQDN. * remove nerdy low-level details by default: endpoints, DERP relay, public key. They're available in JSON mode still for those who need them. * only show endpoint or DERP relay when it's active with the goal of making debugging easier. (so it's easier for users to understand what's happening) The asterisks are gone. * remove Tx/Rx numbers by default for idle peers; only show them when there's traffic. * include peers' owner login names * add CLI option to not show peers (matching --self=true, --peers= also defaults to true) * sort by DNS/host name, not public key * reorder columns	4 years ago
Brad Fitzpatrick	5f07da4854	util/systemd: don't log warnings when not running under systemd It caused our integration tests to fail, which prohibit logging to os.Stderr for test cleanliness reasons.	4 years ago
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	a5dd0bcb09	util/jsonutil: new package The cornerstone API is a more memory-efficient Unmarshal. The savings come from re-using a json.Decoder. BenchmarkUnmarshal-8 4016418 288 ns/op 8 B/op 1 allocs/op BenchmarkStdUnmarshal-8 4189261 283 ns/op 184 B/op 2 allocs/op It also includes a Bytes type to reduce allocations when unmarshalling a non-hex-encoded JSON string into a []byte.

Josh Bleecher Snyder	9784cae23b	util/uniq: add new package This makes it easy to compact slices that contain duplicate elements by sorting and then uniqing. This is an alternative to constructing an intermediate map and then extracting elements from it. It also provides more control over equality than using a map key does.
