Brad Fitzpatrick	c37af58ea4	net/tsdial: move more weirdo dialing into new tsdial package, plumb Not done yet, but this move more of the outbound dial special casing from random packages into tsdial, which aspires to be the one unified place for all outbound dialing shenanigans. Then this plumbs it all around, so everybody is ultimately holding on to the same dialer. As of this commit, macOS/iOS using an exit node should be able to reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt to stay within the Network Extension. A number of steps remain, including but limited to: * move a bunch more random dialing stuff * make netstack-mode tailscaled be able to use exit node's DNS proxy, teaching tsdial's resolver to use it when an exit node is in use.

Brad Fitzpatrick	d5405c66b7	net/tsdial: start of new package to unify all outbound dialing complexity For now this just deletes the net/socks5/tssocks implementation (and the DNSMap stuff from wgengine/netstack) and moves it into net/tsdial. Then initialize a Dialer early in tailscaled, currently only use for the outbound and SOCKS5 proxies. It will be plumbed more later. Notably, it needs to get down into the DNS forwarder for exit node DNS forwading in netstack mode. But it will also absorb all the peerapi setsockopt and netns Dial and tlsdial complexity too.

Brad Fitzpatrick	e6fbc0cd54	cmd/tailscaled, ipn/ipnserver: refactor ipnserver More work towards removing the massive ipnserver.Run and ipnserver.Options and making composable pieces. Work remains. (The getEngine retry loop on Windows complicates things.) For now some duplicate code exists. Once the Windows side is fixed to either not need the retry loop or to move the retry loop into a custom wgengine.Engine wrapper, then we can unify tailscaled_windows.go too.

Brad Fitzpatrick	3618e8d8ac	cmd/tailscaled: rename outbound HTTP proxy flag The old name invited confusion: * is this the HTTP proxy to use ourselves? (no, that's via an environment variable, per proxy conventions) * is this for LetsEncrypt https-to-localhost-http proxying?

Brad Fitzpatrick	7f7a81e5ae	cmd/tailscaled: add func to create ipnserver.Opts To unify the Windows service and non-service/non-Windows paths a bit. And provides a way to make Linux act like Windows for testing. (notably, for testing the fix to #2137) One perhaps visible change of this is that tailscaled.exe when run in cmd.exe/powershell (not as a Windows Service) no longer uses the "_daemon" autostart key. But in addition to being naturally what falls out of this change, that's also what Windows users would likely want, as otherwise the unattended mode user is ignored when the "_daemon" autostart key is specified. Notably, this would let people debug what their normally-run-as-a-service tailscaled is doing, even when they're running in Unattended Mode.

Avery Pennarun	af9328c1b7	log rate limiting: reformat limiter messages, and use nonempty burst size. - Reformat the warning about a message being rate limited to print the format string, rather than the formatted message. This helps give a clue what "type" of message is being limited. - Change the rate limit warning to be [RATE LIMITED] in all caps. This uses less space on each line, plus is more noticeable. - In tailscaled, change the frequency to be less often (once every 5 seconds per format string) but to allow bursts of up to 5 messages.

Wendi Yu	0c69b4e00d	Implement rate limiting on log messages (#356 ) Implement rate limiting on log messages Addresses issue #317, where logs can get spammed with the same message nonstop. Created a rate limiting closure on logging functions, which limits the number of messages being logged per second based on format string. To keep memory usage as constant as possible, the previous cache purging at periodic time intervals has been replaced by an LRU that discards the oldest string when the capacity of the cache is reached.

David Anderson	1ac570def7	wgengine/router: split out from wgengine. The router implementations are logically separate, with their own API. Signed-off-by: David Anderson <danderson@tailscale.com>	5 years ago
Brad Fitzpatrick	45f2b53aca	all: remove unnecessary trailing newlines in format patterns for consistency And document on logger.Logf that it's unnecessary.	5 years ago
Brad Fitzpatrick	322499473e	cmd/tailscaled, wgengine, ipn: add /debug/ipn handler with world state Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
Avery Pennarun	509247bf42	tailscale, tailscaled: update safesocket port number. This makes them able to connect to each other on Windows.	5 years ago
Martin Baillie	8ae3ba0cf5	wgengine: define default tunname for each platform The device name "tailscale0" will be used for all platforms except for OpenBSD where "tun" is enforced by the kernel. `CreateTUN()` in `wireguard-go` will select the next available "tunX" device name on the OpenBSD system.

Brad Fitzpatrick	65e7c58aa4	cmd/tailscale, cmd/tailscaled, paths: add paths package for default paths Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Anderson	0c55777fed	ipn: temporary support for loading legacy relaynode configs. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	15b4d26d92	logpolicy: automatically figure out paths and filenames. The autoselection should pick sensible paths for all of: - Windows (LocalAppData) - Mac (Library/Caches) - Unix user (XDG_CACHE_DIR) - Linux systemd service (CACHE_DIRECTORY) As a last resort, if cache dir lookup fails, plops sufficiently uniquely named files into the current working directory.

David Anderson	85ac82c386	tailscaled: default to a sock in current dir, for development. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	76819e7432	tailscaled: call the network interface tailscale0, not ts0. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
David Anderson	4460bd638b	safesocket: simplify API. On unix, we want to provide a full path to the desired unix socket. On windows, currently we want to provide a TCP port, but someday we'll also provide a "path-ish" object for a named pipe. For now, simplify the API down to exactly a path and a TCP port.

David Anderson	62fb652eef	cmd/tailscaled: run off internal state autonomously. With this change, tailscaled can be restarted and reconnect without interaction from `tailscale`, and `tailscale` is merely there to provide login assistance and adjust preferences.

Brad Fitzpatrick	79295b1138	wgengine: simplify, change some signatures * make RouterGen return an error, not take both tunname and tundev * also remove RouteGen taking a wireguard/device.Device; currently unused * remove derp parameter (it'll work differently) * unexport NewUserspaceRouter in per-OS impls, add documented wrapper Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	5 years ago
David Anderson	dec5d64593	ipn/ipnserver: remove Options.AllowQuit. It was previously used by the MacOS client, but it now does something different. ipnserver should never obey a client's request to exit. Signed-off-by: David Anderson <dave@natulte.net>	5 years ago
