Brad Fitzpatrick	01185e436f	types/result, util/lineiter: add package for a result type, use it This adds a new generic result type (motivated by golang/go#70084) to try it out, and uses it in the new lineutil package (replacing the old lineread package), changing that package to return iterators: sometimes over []byte (when the input is all in memory), but sometimes iterators over results of []byte, if errors might happen at runtime.

Tom Proctor	5f22f72636	hostinfo,build_docker.sh,tailcfg: more reliably detect being in a container (#13826 ) Our existing container-detection tricks did not work on Kubernetes, where Docker is no longer used as a container runtime. Extends the existing go build tags for containers to the other container packages and uses that to reliably detect builds that were created by Tailscale for use in a container. Unfortunately this doesn't necessarily improve detection for users' custom builds, but that's a separate issue. Updates #13825 Signed-off-by: Tom Proctor <tomhjp@users.noreply.github.com>	1 month ago

Aaron Klotz	2cb408f9b1	hostinfo: update Windows hostinfo to include MSIDist registry value We need to expand our enviornment information to include info about the Windows store. Thinking about future plans, it would be nice to include both the packaging mechanism and the distribution mechanism. In this PR we change packageTypeWindows to check a new registry value named MSIDist, and concatenate that value to "msi/" when present. We also remove vestigial NSIS detection.

Aaron Klotz	7132b782d4	hostinfo: use Distro field for distinguishing Windows Server builds Some editions of Windows server share the same build number as their client counterpart; we must use an additional field found in the OS version information to distinguish between them. Even though "Distro" has Linux connotations, it is the most appropriate hostinfo field. What is Windows Server if not an alternate distribution of Windows? This PR populates Distro with "Server" when applicable. Fixes #11785 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	7 months ago

KevinLiang10	7ed3681cbe	tailcfg: Add FirewallMode to NetInfo to record wether host using iptables or nftables To record wether user is using iptables or nftables after we add support to nftables on linux, we are adding a field FirewallMode to NetInfo in HostInfo to reflect what firewall mode the host is running, and form metrics.

Maisem Ali	2ae670eb71	ssh/tailssh: work around lack of scontext in SELinux Trying to SSH when SELinux is enforced results in errors like: ``` ➜ ~ ssh ec2-user@<ip> Last login: Thu Jun 1 22:51:44 from <ip2> ec2-user: no shell: Permission denied Connection to <ip> closed. ``` while the `/var/log/audit/audit.log` has ``` type=AVC msg=audit(1685661291.067:465): avc: denied { transition } for pid=5296 comm="login" path="/usr/bin/bash" dev="nvme0n1p1" ino=2564 scontext=system_u:system_r:unconfined_service_t:s0 tcontext=unconfined_u:unconfined_r:unconfined_t:s0 tclass=process permissive=0 ``` The right fix here would be to somehow install the appropriate context when tailscale is installed on host, but until we figure out a way to do that stop using the `login` cmd in these situations.

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.

Transmitting this information should make this determination a lot easier.
