Brad Fitzpatrick	6cc6e251a9	logpolicy: add debug knob to force logging time to terminal	4 years ago
Brad Fitzpatrick	86c271caba	types/logger: move RusagePrefixLog to logger package, disable by default The RusagePrefixLog is rarely useful, hasn't been useful in a long time, is rarely the measurement we need, and is pretty spammy (and syscall-heavy). Disable it by default. We can enable it when we're debugging memory.	4 years ago

Brad Fitzpatrick	7a2a3955d3	logtail/filch: skip a broken test on Windows Add a TODO with some notes about why it's skipped for now. Updates #50	4 years ago
Brad Fitzpatrick	a6c34bdc28	control/controlclient: also include our own profile (for when no self-owned peers) Fix from regression in previous commit (`0e3048d8e0`) that was caught by e2e tests. In that previous commit, the user's own profile was omitted from the NetworkMap in the case where the user only had one node.	4 years ago
Brad Fitzpatrick	0e3048d8e0	control/controlclient: support delta userprofiles from control I was going to make support for this advertised from the client, but turns out only "tailscale status" even uses the UserProfiles field and fails gracefully (omits that field) if a user profile for a user is missing, so I think we can just reuse the DeltaPeers field from the client to ask the control server to also delta encode the user profiles. For the few users running 1.1.x (unstable) versions between DeltaPeers support (1.1.82) and this (~1.1.541), they'll just sometimes have missing names in "tailscale status --json" or "tailscale status --web" (the only places the UserProfile is used).	4 years ago
Brad Fitzpatrick	82f2fdc194	control/controlclient: adjust some logging point names The previous code read too explicitly like log.Printf("I am here1"), log.Printf("I am here2"). It still is with this change, but prettier, and less subject to code rearranging order.	4 years ago
Brad Fitzpatrick	1fd9958e9d	ipn: wait for initial portpoll result before starting controlclient We were creating the controlclient and starting the portpoll concurrently, which frequently resulted in the first controlclient connection being canceled by the firsdt portpoll result ~milliseconds later, resulting in another HTTP request. Instead, wait a bit for the first portpoll result so it's much less likely to interrupt our controlclient connection. Updates tailscale/corp#557	4 years ago
Brad Fitzpatrick	1819f6f8c8	control/controlclient: set MapRequest.ReadOnly on initial empty endpoint request On startup, clients do a MapRequest with empty endpoints while they learn the DERP map to discover the STUN servers they then query to learn their endpoints. Set MapRequest.ReadOnly on those initial queries to not broadcast the empty endpoints out to peers. The read results will come a half second later (or less). Updates tailscale/corp#557	4 years ago
Brad Fitzpatrick	105a820622	wgengine/magicsock: skip an endpoint update at start-up At startup the client doesn't yet have the DERP map so can't do STUN queries against DERP servers, so it only knows it local interface addresses, not its STUN-mapped addresses. We were reporting the interface-local addresses to control, getting the DERP map, and then immediately reporting the full set of updates. That was an extra HTTP request to control, but worse: it was an extra broadcast from control out to all the peers in the network. Now, skip the initial update if there are no stun results and we don't have a DERP map. More work remains optimizing start-up requests/map updates, but this is a start. Updates tailscale/corp#557	4 years ago
Brad Fitzpatrick	551e1e99e9	net/netns: don't bind to device for localhost connections Fixes derphttp test failures on Windows (for #50).	4 years ago
Brad Fitzpatrick	746f03669c	wgengine: fix lazy wireguard config bug when disco keys change There was a bug with the lazy wireguard config code where, if the minimum set of peers to tell wireguard didn't change, we skipped calling userspaceEngine.updateActivityMapsLocked which updated the various data structures that matched incoming traffic to later reconfigure the minimum config. That meant if an idle peer restarted and changed discovery keys, we skipped updating our maps of disco keys/IPs that would caused us to lazily inflate the config for that peer later if/when it did send traffic.	4 years ago

Alex Brainman	f2ce64f0c6	wgengine/router: unfork winipcfg-go package, use upstream Use golang.zx2c4.com/wireguard/windows/tunnel/winipcfg instead of github.com/tailscale/winipcfg-go package. Updates #760 Signed-off-by: Alex Brainman <alex.brainman@gmail.com>	4 years ago
Brad Fitzpatrick	515866d7c6	ipn, ipnserver, cmd/tailscale: add "server mode" support on Windows This partially (but not yet fully) migrates Windows to tailscaled's StateStore storage system. This adds a new bool Pref, ForceDaemon, defined as: // ForceDaemon specifies whether a platform that normally // operates in "client mode" (that is, requires an active user // logged in with the GUI app running) should keep running after the // GUI ends and/or the user logs out. // // The only current applicable platform is Windows. This // forced Windows to go into "server mode" where Tailscale is // running even with no users logged in. This might also be // used for macOS in the future. This setting has no effect // for Linux/etc, which always operate in daemon mode. Then, when ForceDaemon becomes true, we now write use the StateStore to track which user started it in server mode, and store their prefs under that key. The ipnserver validates the connections/identities and informs that LocalBackend which userid is currently in charge. The GUI can then enable/disable server mode at runtime, without using the CLI. But the "tailscale up" CLI was also fixed, so Windows users can use authkeys or ACL tags, etc. Updates #275	4 years ago
Josh Bleecher Snyder	d027cd81df	tailcfg: restore Roles field to UserProfile	4 years ago
Brad Fitzpatrick	638127530b	ipn/ipnserver: prevent use by multiple Windows users, add HTML status page It was previously possible for two different Windows users to connect to the IPN server at once, but it didn't really work. They mostly stepped on each other's toes and caused chaos. Now only one can control it, but it can be active for everybody else. Necessary dependency step for Windows server/headless mode (#275) While here, finish wiring up the HTTP status page on Windows, now that all the dependent pieces are available.	4 years ago

Brad Fitzpatrick	22c462bd91	wgengine/monitor: fix copy/paste-o to actually monitor route changes Due to a copy/paste-o, we were monitoring address changes twice, and not monitoring route changes at all. Verified with 'tailscale debug --monitor' that this actually works now (while running 'route add 10.3.0.0 mask 255.255.0.0 10.0.0.1' and 'route delete (same)' back and forth in cmd.exe) In practice route changes are accompanied by address changes and this doesn't fix any known issues. I just noticed this while reading this code again. But at least the code does what it was trying to do now.	4 years ago
Brad Fitzpatrick	63d65368db	go.mod: bump wireguard-go for x/sys/unix symbol loss Updates golang/go#41868	4 years ago
Avery Pennarun	6332bc5e08	controlclient: print http errors if result code != 200. Turns out for the particular error I was chasing, it actually returns 200 and zero data. But this code mirrors the same check in the map poll, and is the right thing to do in the name of future debugging. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	0e5f2b90a5	echoRespondToAll: filter.Accept rather than filter.Drop on a match. This function is only called in fake mode, which won't do anything more with the packet after we respond to it anyway, so dropping it in the prefilter is not necessary. And it's kinda semantically wrong: we did not reject it, so telling the upper layer that it was rejected produces an ugly error message. Signed-off-by: Avery Pennarun <apenwarr@tailscale.com>	4 years ago
Avery Pennarun	5041800ac6	wgengine/tstun/faketun: it's a null tunnel, not a loopback. At some point faketun got implemented as a loopback (put a packet in from wireguard, the same packet goes back to wireguard) which is not useful. It's supposed to be an interface that just sinks all packets, and then wgengine adds only and ICMP Echo responder as a layer on top. This caused extremely odd bugs on darwin, where the special case that reinjects packets from local->local was filling the loopback channel and creating an infinite loop (which became jammed since the reader and writer were in the same goroutine).

Brad Fitzpatrick	3e4c46259d	wgengine/magicsock: don't do netchecks either when network is down A continuation of `6ee219a25d` Updates #640	4 years ago
Brad Fitzpatrick	6ee219a25d	ipn, wgengine, magicsock, tsdns: be quieter and less aggressive when offline If no interfaces are up, calm down and stop spamming so much. It was noticed as especially bad on Windows, but probably was bad everywhere. I just have the best network conditions testing on a Windows VM. Updates #604	4 years ago
