Brad Fitzpatrick	3904e4d175	cmd/tta, tstest/natlab/vnet: remove unneeded port 124 log hack, add log buffer The natlab Test Agent (tta) still had its old log streaming hack in place where it dialed out to anything on TCP port 124 and those logs were streamed to the host running the tests. But we'd since added gokrazy syslog streaming support, which made that redundant. So remove all the port 124 stuff. And then make sure we log to stderr so gokrazy logs it to syslog. Also, keep the first 1MB of logs in memory in tta too, exported via localhost:8034/logs for interactive debugging. That was very useful during debugging when I added IPv6 support. (which is coming in future PRs) Updates #13038 Change-Id: Ieed904a704410b9031d5fd5f014a73412348fa7f Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 months ago

Brad Fitzpatrick	b091264c0a	cmd/systray: set ipn.NotifyNoPrivateKeys, permit non-operator use Otherwise you get "Access denied: watch IPN bus access denied, must set ipn.NotifyNoPrivateKeys when not running as admin/root or operator". This lets a non-operator at least start the app and see the status, even if they can't change everything. (the web UI is unaffected by operator) A future change can add a LocalAPI call to check permissions and guide people through adding a user as an operator (perhaps the web client can do that?)

Will Norris	3c66ee3f57	cmd/systray: add a basic linux systray app This adds a systray app for linux, similar to the apps for macOS and windows. There are already a number of community-developed systray apps, but most of them are either long abandoned, are built for a specific desktop environment, or simply wrap the tailscale CLI. This uses fyne.io/systray (a fork of github.com/getlantern/systray) which uses newer D-Bus specifications to render the tray icon and menu. This results in a pretty broad support for modern desktop environments. This initial commit lacks a number of features like profile switching, device listing, and exit node selection. This is really focused on the application structure, the interaction with LocalAPI, and some system integration pieces like the app icon, notifications, and the clipboard.

Jonathan Nobels	1191eb0e3d	tstest/natlab: add unix address to writer for dgram mode updates tailcale/corp#22371 For dgram mode, we need to store the write addresses of the client socket(s) alongside the writer functions and the write operation needs to use WriteToUnix. Unix also has multiple clients writing to the same socket, so the serve method is modified to handle packets from multiple mac addresses.

Percy Wegmann	4b525fdda0	ssh/tailssh: only chdir incubator process to user's homedir when necessary and possible Instead of changing the working directory before launching the incubator process, this now just changes the working directory after dropping privileges, at which point we're more likely to be able to enter the user's home directory since we're running as the user. For paths that use the 'login' or 'su -l' commands, those already take care of changing the working directory to the user's home directory.

Nick Khyl	af3d3c433b	types/prefs: add a package containing generic preference types This adds a new package containing generic types to be used for defining preference hierarchies. These include prefs.Item, prefs.List, prefs.StructList, and prefs.StructMap. Each of these types represents a configurable preference, holding the preference's state, value, and metadata. The metadata includes the default value (if it differs from the zero value of the Go type) and flags indicating whether a preference is managed via syspolicy or is hidden/read-only for another reason. This information can be marshaled and sent to the GUI, CLI and web clients as a source of truth regarding preference configuration, management, and visibility/mutability states. We plan to use these types to define device preferences, such as the updater preferences, the permission mode to be used on Windows with #tailscale/corp#18342, and certain global options that are currently exposed as tailscaled flags. We also aim to eventually use these types for profile-local preferences in ipn.Prefs and and as a replacement for ipn.MaskedPrefs. The generic preference types are compatible with the tailscale.com/cmd/viewer and tailscale.com/cmd/cloner utilities. Updates #12736 Signed-off-by: Nick Khyl <nickk@tailscale.com>	3 months ago
Anton Tolchanov	151b77f9d6	cmd/tl-longchain: tool to re-sign nodes with long rotation signatures In Tailnet Lock, there is an implicit limit on the number of rotation signatures that can be chained before the signature becomes too long. This program helps tailnet admins to identify nodes that have signatures with long chains and prints commands to re-sign those node keys with a fresh direct signature. It's a temporary mitigation measure, and we will remove this tool as we design and implement a long-term approach for rotation signatures. Example output: ``` 2024/08/20 18:25:03 Self: does not need re-signing 2024/08/20 18:25:03 Visible peers with valid signatures: 2024/08/20 18:25:03 Peer xxx2.yy.ts.net.

Percy Wegmann	7d83056a1b	ssh/tailssh: fix SSH on busybox systems This involved the following: 1. Pass the su command path as first of args in call to unix.Exec to make sure that busybox sees the correct program name. Busybox is a single executable userspace that implements various core userspace commands in a single binary. You'll see it used via symlinking, so that for example /bin/su symlinks to /bin/busybox. Busybox knows that you're trying to execute /bin/su because argv[0] is '/bin/su'. When we called unix.Exec, we weren't including the program name for argv[0], which caused busybox to fail with 'applet not found', meaning that it didn't know which command it was supposed to run. 2. Tell su to whitelist the SSH_AUTH_SOCK environment variable in order to support ssh agent forwarding. 3. Run integration tests on alpine, which uses busybox. 4. Increment CurrentCapabilityVersion to allow turning on SSH V2 behavior from control. Fixes #12849 Signed-off-by: Percy Wegmann <percy@tailscale.com>	3 months ago
Jordan Whited	7675c3ebf2	wgengine/netstack/gro: exclude importation of gVisor GRO pkg on iOS (#13202 ) In `df6014f1d7` we removed build tag gating preventing importation, which tripped a NetworkExtension limit test in corp. This was a reversal of `25f0a3fc8f` which actually made the situation worse, hence the simplification. This commit goes back to the strategy in `25f0a3fc8f`, and gets us back under the limit in my local testing. Admittedly, we don't fully understand the effects of importing or excluding importation of this package, and have seen mixed results, but this commit allows us to move forward again.

Jordan Whited	df6014f1d7	net/tstun,wgengine{/netstack/gro}: refactor and re-enable gVisor GRO for Linux (#13172 ) In `2f27319baf` we disabled GRO due to a data race around concurrent calls to tstun.Wrapper.Write(). This commit refactors GRO to be thread-safe, and re-enables it on Linux. This refactor now carries a GRO type across tstun and netstack APIs with a lifetime that is scoped to a single tstun.Wrapper.Write() call. In `25f0a3fc8f` we used build tags to prevent importation of gVisor's GRO package on iOS as at the time we believed it was contributing to additional memory usage on that platform. It wasn't, so this commit simplifies and removes those build tags.

Jonathan Nobels	8fad8c4b9b	tstest/tailmac: add customized macOS virtualization tooling (#13146 ) updates tailcale/corp#22371 Adds custom macOS vm tooling. See the README for the general gist, but this will spin up VMs with unixgram capable network interfaces listening to a named socket, and with a virtio socket device for host-guest communication. We can add other devices like consoles, serial, etc as needed. The whole things is buildable with a single make command, and everything is controllable via the command line using the TailMac utility. This should all be generally functional but takes a few shortcuts with error handling and the like. The virtio socket device support has not been tested and may require some refinement.

Andrea Gottardo	5cbbb48c2e	health/dns: reduce severity of DNS unavailable warning (#13152 ) `DNS unavailable` was marked as a high severity warning. On Android (and other platforms), these trigger a system notification. Here we reduce the severity level to medium. A medium severity warning will still display the warning icon on platforms with a tray icon because of the `ImpactsConnectivity=true` flag being set here, but it won't show a notification anymore. If people enter an area with bad cellular reception, they're bound to receive so many of these notifications and we need to reduce notification fatigue.

Andrew Dunham	e107977f75	wgengine/magicsock: disable SIO_UDP_NETRESET on Windows By default, Windows sets the SIO_UDP_CONNRESET and SIO_UDP_NETRESET options on created UDP sockets. These behaviours make the UDP socket ICMP-aware; when the system gets an ICMP message (e.g. an "ICMP Port Unreachable" message, in the case of SIO_UDP_CONNRESET), it will cause the underlying UDP socket to throw an error. Confusingly, this can occur even on reads, if the same UDP socket is used to write a packet that triggers this response. The Go runtime disabled the SIO_UDP_CONNRESET behavior in 3114bd6, but did not change SIO_UDP_NETRESET–probably because that socket option isn't documented particularly well. Various other networking code seem to disable this behaviour, such as the Godot game engine (godotengine/godot#22332) and the Eclipse TCF agent (link below). Others appear to work around this by ignoring the error returned (anacrolix/dht#16, among others). For now, until it's clear whether this ends up in the upstream Go implementation or not, let's also disable the SIO_UDP_NETRESET in a similar manner to SIO_UDP_CONNRESET.
