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.

Aaron Klotz	855f79fad7	cmd/tailscaled, util/winutil: changes to process and token APIs in winutil This PR changes the internal getTokenInfo function to use generics. I also removed our own implementations for obtaining a token's user and primary group in favour of calling the ones now available in x/sys/windows. Furthermore, I added two new functions for working with tokens, logon session IDs, and Terminal Services / RDP session IDs. I modified our privilege enabling code to allow enabling of multiple privileges via one single function call. Finally, I added the ProcessImageName function and updated the code in tailscaled_windows.go to use that instead of directly calling the underlying API. All of these changes will be utilized by subsequent PRs pertaining to this issue. Updates https://github.com/tailscale/corp/issues/13998 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	1 year ago

Aaron Klotz	47019ce1f1	cmd/tailscaled: pre-load wintun.dll using a fully-qualified path In corp PR #14970 I updated the installer to set a security mitigation that always forces system32 to the front of the Windows dynamic linker's search path. Unfortunately there are other products out there that, partying like it's 1995, drop their own, older version of wintun.dll into system32. Since we look there first, we end up loading that old version. We can fix this by preloading wintun using a fully-qualified path. When wintun-go then loads wintun, the dynamic linker will hand it the module that was previously loaded by us. Fixes #10023, #10025, #10052 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	1 year ago

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.

Aaron Klotz	95671b71a6	ipn, safesocket: use Windows token in LocalAPI On Windows, the idiomatic way to check access on a named pipe is for the server to impersonate the client on its current OS thread, perform access checks using the client's access token, and then revert the OS thread's access token back to its true self. The access token is a better representation of the client's rights than just a username/userid check, as it represents the client's effective rights at connection time, which might differ from their normal rights. This patch updates safesocket to do the aforementioned impersonation, extract the token handle, and then revert the impersonation. We retain the token handle for the remaining duration of the connection (the token continues to be valid even after we have reverted back to self). Since the token is a property of the connection, I changed ipnauth to wrap the concrete net.Conn to include the token. I then plumbed that change through ipnlocal, ipnserver, and localapi as necessary. I also added a PermitLocalAdmin flag to the localapi Handler which I intend to use for controlling access to a few new localapi endpoints intended for configuring auto-update.

This ensures that if the upstream DNS server does not reply over UDP (or if the response packet is blocked, or there's an error), we can still make queries if the server replies to TCP queries.

Aaron Klotz	5fb1695bcb	util/osdiag, util/osdiag/internal/wsc: add code to probe the Windows Security Center for installed software The Windows Security Center is a component that manages the registration of security products on a Windows system. Only products that have obtained a special cert from Microsoft may register themselves using the WSC API. Practically speaking, most vendors do in fact sign up for the program as it enhances their legitimacy. From our perspective, this is useful because it gives us a high-signal source of information to query for the security products installed on the system. I've tied this query into the osdiag package and is run during bugreports. It uses COM bindings that were automatically generated by my prototype metadata processor, however that program still has a few bugs, so I had to make a few manual tweaks. I dropped those binding into an internal package because (for the moment, at least) they are effectively purpose-built for the osdiag use case. We also update the wingoes dependency to pick up BSTR.

Brad Fitzpatrick	88cc0ad9f7	util/linuxfw: remove yet-unused code to fix linux/arm64 crash The util/linuxfw/iptables.go had a bunch of code that wasn't yet used (in prep for future work) but because of its imports, ended up initializing code deep within gvisor that panicked on init on arm64 systems not using 4KB pages. This deletes the unused code to delete the imports and remove the panic. We can then cherry-pick this back to the branch and restore it later in a different way. A new test makes sure we don't regress in the future by depending on the panicking package in question. Fixes #8658 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago

Joe Tsai	84c99fe0d9	logtail: be less aggressive about re-uploads (#8117 ) The retry logic was pathological in the following ways: * If we restarted the logging service, any pending uploads would be placed in a retry-loop where it depended on backoff.Backoff, which was too aggresive. It would retry failures within milliseconds, taking at least 10 retries to hit a delay of 1 second. * In the event where a logstream was rate limited, the aggressive retry logic would severely exacerbate the problem since each retry would also log an error message. It is by chance that the rate of log error spam does not happen to exceed the rate limit itself. We modify the retry logic in the following ways: * We now respect the "Retry-After" header sent by the logging service. * Lacking a "Retry-After" header, we retry after a hard-coded period of 30 to 60 seconds. This avoids the thundering-herd effect when all nodes try reconnecting to the logging service at the same time after a restart. * We do not treat a status 400 as having been uploaded. This is simply not the behavior of the logging service. Updates #tailscale/corp#11213 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	2 years ago

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

Charlotte Brandhorst-Satzkorn	ddb4040aa0	wgengine/magicsock: add address selection for wireguard only endpoints (#7979 ) This change introduces address selection for wireguard only endpoints. If a endpoint has not been used before, an address is randomly selected to be used based on information we know about, such as if they are able to use IPv4 or IPv6. When an address is initially selected, we also initiate a new ICMP ping to the endpoints addresses to determine which endpoint offers the best latency. This information is then used to update which endpoint we should be using based on the best possible route. If the latency is the same for a IPv4 and an IPv6 address, IPv6 will be used.

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.

Anton Tolchanov	11e6247d2a	tsweb: expose native Prometheus metrics in /debug/varz The handler will expose built-in process and Go metrics by default, which currently duplicate some of the expvar-proxied metrics (`goroutines` vs `go_goroutines`, `memstats` vs `go_memstats`), but as long as their names are different, Prometheus server will just scrape both. This will change /debug/varz behaviour for most tsweb binaries, but notably not for control, which configures a `tsweb.VarzHandler` [explicitly](`a5b5d5167f/cmd/tailcontrol/tailcontrol.go (L779)`) Updates https://github.com/tailscale/corp/issues/10205 Signed-off-by: Anton Tolchanov <anton@tailscale.com>	2 years ago
Aaron Klotz	90fd04cbde	ipn/ipnlocal, util/winutil/policy: modify Windows profile migration to load legacy prefs from within tailscaled I realized that a lot of the problems that we're seeing around migration and LocalBackend state can be avoided if we drive Windows pref migration entirely from within tailscaled. By doing it this way, tailscaled can automatically perform the migration as soon as the connection with the client frontend is established. Since tailscaled is already running as LocalSystem, it already has access to the user's local AppData directory. The profile manager already knows which user is connected, so we simply need to resolve the user's prefs file and read it from there. Of course, to properly migrate this information we need to also check system policies. I moved a bunch of policy resolution code out of the GUI and into a new package in util/winutil/policy.
