Jonathan Nobels	8a8ecac6a7	net/dns, cmd/tailscaled: plumb system health tracker into dns cleanup (#12969) ... fixes tailscale#12968 The dns manager cleanup func was getting passed a nil health tracker, which will panic. Fixed to pass it the system health tracker. Signed-off-by: Jonathan Nobels <jonathan@tailscale.com>	3 months ago
Nick Khyl	c32efd9118	various: create a catch-all NRPT rule when "Override local DNS" is enabled on Windows ... Without this rule, Windows 8.1 and newer devices issue parallel DNS requests to DNS servers associated with all network adapters, even when "Override local DNS" is enabled and/or a Mullvad exit node is being used, resulting in DNS leaks. This also adds "disable-local-dns-override-via-nrpt" nodeAttr that can be used to disable the new behavior if needed.

Maisem Ali	42cfbf427c	tsnet,wgengine/netstack: add ListenPacket and tests ... This adds a new ListenPacket function on tsnet.Server which acts mostly like `net.ListenPacket`. Unlike `Server.Listen`, this requires listening on a specific IP and does not automatically listen on both V4 and V6 addresses of the Server when the IP is unspecified. To test this, it also adds UDP support to tsdial.Dialer.UserDial and plumbs it through the localapi. Then an associated test to make sure the UDP functionality works from both sides.

Brad Fitzpatrick	727c0d6cfd	ipn/ipnserver: close a small race in ipnserver, ~simplify code ... There was a small window in ipnserver after we assigned a LocalBackend to the ipnserver's atomic but before we Start'ed it where our initalization Start could conflict with API calls from the LocalAPI. Simplify that a bit and lay out the rules in the docs. Updates #12028 Change-Id: Ic5f5e4861e26340599184e20e308e709edec68b1 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	6 months ago
Brad Fitzpatrick	3672f29a4e	net/netns, net/dns/resolver, etc: make netmon required in most places ... The goal is to move more network state accessors to netmon.Monitor where they can be cheaper/cached. But first (this change and others) we need to make sure the one netmon.Monitor is plumbed everywhere. Some notable bits: * tsdial.NewDialer is added, taking a now-required netmon * because a tsdial.Dialer always has a netmon, anything taking both a Dialer and a NetMon is now redundant; take only the Dialer and get the NetMon from that if/when needed. * netmon.NewStatic is added, primarily for tests Updates tailscale/corp#10910 Updates tailscale/corp#18960 Updates #7967 Updates #3299 Change-Id: I877f9cb87618c4eb037cee098241d18da9c01691 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	6 months ago

James Tucker	db760d0bac	cmd/tailscaled: move cleanup to an implicit action during startup ... This removes a potentially increased boot delay for certain boot topologies where they block on ExecStartPre that may have socket activation dependencies on other system services (such as systemd-resolved and NetworkManager). Also rename cleanup to clean up in affected/immediately nearby places per code review commentary. Fixes #11599 Signed-off-by: James Tucker <james@tailscale.com>	7 months ago
Maisem Ali	3f4c5daa15	wgengine/netstack: remove SubnetRouterWrapper ... It was used when we only supported subnet routers on linux and would nil out the SubnetRoutes slice as no other router worked with it, but now we support subnet routers on ~all platforms. The field it was setting to nil is now only used for network logging and nowhere else, so keep the field but drop the SubnetRouterWrapper as it's not useful.

Nick Khyl	7ef1fb113d	cmd/tailscaled, ipn/ipnlocal, wgengine: shutdown tailscaled if wgdevice is closed ... Tailscaled becomes inoperative if the Tailscale Tunnel wintun adapter is abruptly removed. wireguard-go closes the device in case of a read error, but tailscaled keeps running. This adds detection of a closed WireGuard device, triggering a graceful shutdown of tailscaled. It is then restarted by the tailscaled watchdog service process.

Andrew Dunham	46bdbb3878	cmd/tailscaled, tsnet: don't return an interface containing a nil pointer ... This tripped me up when I was testing something and wrote: if conn != nil { conn.Close() } In netstack mode, when an error occurred we were getting a non-nil error and a non-nil interface that contained a nil pointer. Instead, just return a nil interface value. Updates #cleanup Signed-off-by: Andrew Dunham <andrew@du.nham.ca> Change-Id: Id9ef3dd24529e0e8c53adc60ed914c31fbb10cc4	10 months ago
Aaron Klotz	e32a064659	cmd/tailscaled: don't create a network monitor in the parent tailscaled on Windows ... The service is only used as a watchdog and for piping logs from the child process.

Sonia Appasamy	c2fe123232	cmd/tailscaled: update ConfigureWebClient's UseSocketOnly value ... Previously were always setting `UseSocketOnly` because we were comparing `args.socketpath != ""`, but `args.socketpath` flag always gets filled with `paths.DefaultTailscaledSocket()` when not provided. Rather than comparing to the empty string, compare to the default value to determine if `UseSocketOnly` should be set.

Sonia Appasamy	89953b015b	ipn/ipnlocal,client/web: add web client to tailscaled ... Allows for serving the web interface from tailscaled, with the ability to start and stop the server via localapi endpoints (/web/start and /web/stop). This will be used to run the new full management web client, which will only be accessible over Tailscale (with an extra auth check step over noise) from the daemon. This switch also allows us to run the web interface as a long-lived service in environments where the CLI version is restricted to CGI, allowing us to manage certain auth state in memory. ipn/ipnlocal/web is stubbed out in ipn/ipnlocal/web_stub for ios builds to satisfy ios restriction from adding "text/template" and "html/template" dependencies.

Brad Fitzpatrick	4e91cf20a8	control/controlknobs, all: add plumbed Knobs type, not global variables ... Previously two tsnet nodes in the same process couldn't have disjoint sets of controlknob settings from control as both would overwrite each other's global variables.

To repro, add this to tstest/integration: func TestFailInFewSeconds(t *testing.T) { t.Parallel() time.Sleep(3 * time.Second) os.Exit(1) t.Fatal("boom") } Those three seconds let the other parallel tests (with all their tailscaled child processes) start up and start running their tests, but then we violently os.Exit(1) the test driver and all the children were kept alive (and were spinning away, using all available CPU in gvisor scheduler code, which is a separate scary issue) Updates #cleanup Change-Id: I9c891ed1a1ec639fb2afec2808c04dbb8a460e0e Co-authored-by: Maisem Ali <maisem@tailscale.com> Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago

Chenyang Gao	b9fb8ac702	fix sys.Set(router) issue will crash the daemon in some OSs ... Signed-off-by: Chenyang Gao <gps949@outlook.com> in commit 6e96744, the tsd system type has been added. Which will cause the daemon will crash on some OSs (Windows, darwin and so on). The root cause is that on those OSs, handleSubnetsInNetstack() will return true and set the conf.Router with a wrapper. Later in NewUserspaceEngine() it will do subsystem set and found that early set router mismatch to current value, then panic.	2 years ago

Mihai Parparita	7330aa593e	all: avoid repeated default interface lookups ... On some platforms (notably macOS and iOS) we look up the default interface to bind outgoing connections to. This is both duplicated work and results in logspam when the default interface is not available (i.e. when a phone has no connectivity, we log an error and thus cause more things that we will try to upload and fail). Fixed by passing around a netmon.Monitor to more places, so that we can use its cached interface state. Fixes #7850 Updates #7621 Signed-off-by: Mihai Parparita <mihai@tailscale.com>	2 years ago
Mihai Parparita	4722f7e322	all: move network monitoring from wgengine/monitor to net/netmon ... We're using it in more and more places, and it's not really specific to our use of Wireguard (and does more just link/interface monitoring). Also removes the separate interface we had for it in sockstats -- it's a small enough package (we already pull in all of its dependencies via other paths) that it's not worth the extra complexity.

Anton Tolchanov	8546ff98fb	tsweb: move varz handler(s) into separate modules ... This splits Prometheus metric handlers exposed by tsweb into two modules: - `varz.Handler` exposes Prometheus metrics generated by our expvar converter; - `promvarz.Handler` combines our expvar-converted metrics and native Prometheus metrics. By default, tsweb will use the promvarz handler, however users can keep using only the expvar converter. Specifically, `tailscaled` now uses `varz.Handler` explicitly, which avoids a dependency on the (heavyweight) Prometheus client.
