Brad Fitzpatrick	c88506caa6	ipn/ipnlocal: add Wake-on-LAN function to peerapi No CLI support yet. Just the curl'able version if you know the peerapi port. (like via a TSMP ping) Updates #306 Change-Id: I0662ba6530f7ab58d0ddb24e3664167fcd1c4bcf Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	3f7cc3563f	ipn: always treat login.tailscale.com as controlplane.tailscale.com Like `888e50e1`, but more aggressive. Updates #4538 (likely fixes) Updates #3488 Change-Id: I3924eee9110e47bdba926ce12954253bf2413040 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago

Brad Fitzpatrick	50eb8c5add	cmd/tailscale: mostly fix 'tailscale ssh' on macOS (sandbox) Still a little wonky, though. See the tcsetattr error and inability to hit Ctrl-D, for instance: bradfitz@laptop ~ % tailscale.app ssh foo@bar tcsetattr: Operation not permitted # Authentication checked with Tailscale SSH. # Time since last authentication: 1h13m22s foo@bar:~$ ^D ^D ^D Updates #4518 Updates #4529 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	48e5f4ff88	cmd/tailscale/cli: add 'debug stat' subcommand For debugging what's visible inside the macOS sandbox. But could also be useful for giving users portable commands during debugging without worrying about which OS they're on. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 years ago
Brad Fitzpatrick	21413392cf	safesocket: fix CLI on standalone mac GUI build Tested three macOS Tailscale daemons: - App Store (Network Extension) - Standalone (macsys) - tailscaled And two types of local IPC each: - IPN - HTTP And two CLI modes: - sandboxed (running the GUI binary as the CLI; normal way) - open source CLI hitting GUI (with #4525) Bonus: simplifies the code.

Brad Fitzpatrick	3601b43530	ipn: add IPCVersion override func I've done this a handful of times in the past and again today. Time to make it a supported thing for the future.

Tom DNetto	5fb8e01a8b	net/dns/resolver: add metric for number of truncated dns packets Updates #2067 This should help us determine if more robust control of edns parameters + implementing answer truncation is warranted, given its likely complexity.

Maisem Ali	80ba161c40	wgengine/monitor: do not ignore changes to pdp_ip* One current theory (among other things) on battery consumption is that magicsock is resorting to using the IPv6 over LTE even on WiFi. One thing that could explain this is that we do not get link change updates for the LTE modem as we ignore them in this list. This commit makes us not ignore changes to `pdp_ip` as a test.

Brad Fitzpatrick	e97209c6bf	net/dns: add tailscaled-on-macOS DNS OSConfigurator This populates DNS suffixes ("ts.net", etc) in /etc/resolver/* files to point to 100.100.100.100 so MagicDNS works.

Brad Fitzpatrick	53588f632d	Revert "wgengine/router,util/kmod: load & log xt_mark" This reverts commit `8d6793fd70`. Reason: breaks Android build (cgo/pthreads addition) We can try again next cycle.

James Tucker	8d6793fd70	wgengine/router,util/kmod: load & log xt_mark Attempt to load the xt_mark kernel module when it is not present. If the load fails, log error information. It may be tempting to promote this failure to an error once it has been in use for some time, so as to avoid reaching an error with the iptables invocation, however, there are conditions under which the two stages may disagree - this change adds more useful breadcrumbs. Example new output from tailscaled running under my WSL2: ``` router: ensure module xt_mark: "/usr/sbin/modprobe xt_mark" failed: exit status 1; modprobe: FATAL: Module xt_mark not found in directory /lib/modules/5.10.43.3-microsoft-standard-WSL2 ``` Background: There are two places to lookup modules, one is `/proc/modules` "old", the other is `/sys/module/` "new". There was query_modules(2) in linux <2.6, alas, it is gone. In a docker container in the default configuration, you would get /proc/modules and /sys/module/ both populated. lsmod may work file, modprobe will fail with EPERM at `finit_module()` for an unpriviliged container. In a priviliged container the load may succeed, if some conditions are met. This condition should be avoided, but the code landing in this change does not attempt to avoid this scenario as it is both difficult to detect, and has a very uncertain impact. In an nspawn container `/proc/modules` is populated, but `/sys/module` does not exist. Modern `lsmod` versions will fail to gather most module information, without sysfs being populated with module information. In WSL2 modules are likely missing, as the in-use kernel typically is not provided by the distribution filesystem, and WSL does not mount in a module filesystem of its own. Notably the WSL2 kernel supports iptables marks without listing the xt_mark module in /sys/module, and /proc/modules is empty. On a recent kernel, we can ask the capabilities system about SYS_MODULE, that will help to disambiguate between the non-privileged container case and just being root. On older kernels these calls may fail. Update #4329 Signed-off-by: James Tucker <james@tailscale.com>	3 years ago

Denton Gentry	c2b907c965	scripts/installer: support LinuxMint Debian. The primary distribution for LinuxMint is based on Ubuntu, but there is an alternate Debian-based distribution called LMDE. Both variations identify themselves as "linuxmint" We added UBUNTU_VERSION to the Ubuntu handling for linuxmint, the only distribution so far found to do this. Instead, split linuxmint out into its own case and use either UBUNTU_VERSION or DEBIAN_VERSION, whichever is present. Tested on an LMDE 5 (elsie) VM.

Brad Fitzpatrick	1b89662eff	ipn/ipnlocal: make peerapi listener on Android avoid the kernel We intercept the peerapi port in netstack anyway, so there's no reason the linux kernel on Android needs to know about it. It's only getting in the way and causing problems for reasons we don't fully understand. But we don't even need to understand it because it's not relevant anymore. Instead, provide a dummy net.Listener that just sits and blocks to pacify the rest of the code that assumes it can be stuck in a Listener.Accept call and call Listener.Close and Listener.Addr. We'll likely do this for all platforms in the future, if/when we also link in netstack on iOS.
