Andrea Gottardo	6288c9b41e	version/prop: remove IsMacAppSandboxEnabled (#11461) ... Fixes tailscale/corp#18441 For a few days, IsMacAppStore() has been returning `false` on App Store builds (IPN-macOS target in Xcode). I regressed this in #11369 by introducing logic to detect the sandbox by checking for the APP_SANDBOX_CONTAINER_ID environment variable. I thought that was a more robust approach instead of checking the name of the executable. However, it appears that on recent macOS versions this environment variable is no longer getting set, so we should go back to the previous logic that checks for the executable path, or HOME containing references to macsys. This PR also adds additional checks to the logic by also checking XPC_SERVICE_NAME in addition to HOME where possible. That environment variable is set inside the network extension, either macos or macsys and is good to look at if for any reason HOME is not set.	8 months ago

Andrea Gottardo	08ebac9acb	version,cli,safesocket: detect non-sandboxed macOS GUI (#11369) ... Updates ENG-2848 We can safely disable the App Sandbox for our macsys GUI, allowing us to use `tailscale ssh` and do a few other things that we've wanted to do for a while. This PR: - allows Tailscale SSH to be used from the macsys GUI binary when called from a CLI - tweaks the detection of client variants in prop.go, with new functions `IsMacSys()`, `IsMacSysApp()` and `IsMacAppSandboxEnabled()` Signed-off-by: Andrea Gottardo <andrea@gottardo.me>	9 months ago
Irbe Krumina	ea55f96310	cmd/tailscale/cli: fix configuring partially empty kubeconfig (#11417) ... When a user deletes the last cluster/user/context from their kubeconfig via 'kubectl delete-[cluster|user|context] command, kubectx sets the relevant field in kubeconfig to 'null'. This was breaking our conversion logic that was assuming that the field is either non-existant or is an array.

Andrew Lytvynov	decd9893e4	ipn/ipnlocal: validate domain of PopBrowserURL on default control URL (#11394) ... If the client uses the default Tailscale control URL, validate that all PopBrowserURLs are under tailscale.com or *.tailscale.com. This reduces the risk of a compromised control plane opening phishing pages for example. The client trusts control for many other things, but this is one easy way to reduce that trust a bit.

Andrew Lytvynov	48eef9e6eb	clientupdate: do not allow msiexec to reboot the OS (#11409) ... According to https://learn.microsoft.com/en-us/windows/win32/msi/standard-installer-command-line-options#promptrestart, `/promptrestart` is ignored with `/quiet` is set, so msiexec.exe can sometimes silently trigger a reboot. The best we can do to reduce unexpected disruption is to just prevent restarts, until the user chooses to do it. Restarts aren't normally needed for Tailscale updates, but there seem to be some situations where it's triggered. Updates #18254 Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	9 months ago

Andrew Dunham	7429e8912a	wgengine/netstack: fix bug with duplicate SYN packets in client limit ... This fixes a bug that was introduced in #11258 where the handling of the per-client limit didn't properly account for the fact that the gVisor TCP forwarder will return 'true' to indicate that it's handled a duplicate SYN packet, but not launch the handler goroutine. In such a case, we neither decremented our per-client limit in the wrapper function, nor did we do so in the handler function, leading to our per-client limit table slowly filling up without bound. Fix this by doing the same duplicate-tracking logic that the TCP forwarder does so we can detect such cases and appropriately decrement our in-flight counter.

James Tucker	055117ad45	util/linuxfw: fix support for containers without IPv6 iptables filters (#11381) ... There are container environments such as GitHub codespaces that have partial IPv6 support - routing support is enabled at the kernel level, but lacking IPv6 filter support in the iptables module. In the specific example of the codespaces environment, this also has pre-existing legacy iptables rules in the IPv4 tables, as such the nascent firewall mode detection will always pick iptables. We would previously fault trying to install rules to the filter table, this catches that condition earlier, and disables IPv6 support under these conditions.

Irbe Krumina	90c4067010	util/linuxfw: add container-friendly IPv6 NAT check (#11353) ... Remove IPv6 NAT check when routing is being set up using nftables.
