Eng Zer Jun	f0347e841f	refactor: move from io/ioutil to io and os packages The io/ioutil package has been deprecated as of Go 1.16 [1]. This commit replaces the existing io/ioutil functions with their new definitions in io and os packages.

Brad Fitzpatrick	45a3de14a6	cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically. Making it easier to set flags for other platforms is tracked in #5114.

Brad Fitzpatrick	6b71568eb7	util/cloudenv: add Azure support & DNS IPs And rewrite cloud detection to try to do only zero or one metadata discovery request for all clouds, only doing a first (or second) as confidence increases. Work remains for Windows, but a start. And add Cloud to tailcfg.Hostinfo, which helped with testing using "tailcfg debug hostinfo".

Tom DNetto	24cd26534f	hostinfo, tailcfg: add desktop detection on Linux to hostinfo From the machines tab its hard to differenciate desktop Linux installs from server Linux installs. Transmitting this information should make this determination a lot easier. Due to the reality that tailscaled is likely a system process, the standard checks based on XDG_SESSION_TYPE or DISPLAY environment variables are not possible (those variables won't be set). Instead, we look for listening unix sockets that are typical of desktop installs. Signed-off-by: Tom DNetto <tom@tailscale.com>	4 years ago

Aaron Klotz	e31d68d64e	hostinfo: use the sentinel value set by the MSI installer to detect MSI package type The MSI installer sets a special sentinel value that we can use to detect it. I also removed the code that bails out when the installation path is not `Program Files`, as both the NSIS and MSI installers permit the user to install to a different path.

Aaron Klotz	7d8feb2784	hostinfo: change Windows implementation to directly query version information using API and registry We replace the cmd.exe invocation with RtlGetNtVersionNumbers for the first three fields. On Windows 10+, we query for the fourth field which is available via the registry. The fourth field is not really documented anywhere; Firefox has been querying it successfully since Windows 10 was released, so we can be pretty confident in its longevity at this point.

Denton Gentry	e28bc49e5f	netns_linux: remove special handling for tests. With netns handling localhost now, existing tests no longer need special handling. The tests set up their connections to localhost, and the connections work without fuss. Remove the special handling for tests. Also remove the hostinfo.TestCase support, since this was the only use of it. It can be added back later if really needed, but it would be better to try to make tests work without special cases.

Denton Gentry	d3697053c9	hostinfo: add AWS Fargate. Several other AWS services like App Run and Lightsail Containers appear to be layers atop Fargate, to the point that we cannot easily tell them apart from within the container. Contacting the metadata service would distinguish them, but doing that from inside tailscaled seems uncalled for. Just report them as Fargate.
