Brad Fitzpatrick	c56e94af2d	ipn: avoid useless no-op WriteState calls Rather than make each ipn.StateStore implementation guard against useless writes (a write of the same value that's already in the store), do writes via a new wrapper that has a fast path for the unchanged case. This then fixes profileManager's flood of useless writes to AWS SSM, etc. Updates #8785 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago

Andrew Lytvynov	c1ecae13ab	ipn/{ipnlocal,localapi}: actually renew certs before expiry (#8731 ) While our `shouldStartDomainRenewal` check is correct, `getCertPEM` would always bail if the existing cert is not expired. Add the same `shouldStartDomainRenewal` check to `getCertPEM` to make it proceed with renewal when existing certs are still valid but should be renewed. The extra check is expensive (ARI request towards LetsEncrypt), so cache the last check result for 1hr to not degrade `tailscale serve` performance. Also, asynchronous renewal is great for `tailscale serve` but confusing for `tailscale cert`. Add an explicit flag to `GetCertPEM` to force a synchronous renewal for `tailscale cert`.

Charlotte Brandhorst-Satzkorn	35bdbeda9f	cli: introduce exit-node subcommand to list and filter exit nodes This change introduces a new subcommand, `exit-node`, along with a subsubcommand of `list` and a `--filter` flag. Exit nodes without location data will continue to be displayed when `status` is used. Exit nodes with location data will only be displayed behind `exit-node list`, and in status if they are the active exit node. The `filter` flag can be used to filter exit nodes with location data by country. Exit nodes with Location.Priority data will have only the highest priority option for each country and city listed. For countries with multiple cities, a <Country> <Any> option will be displayed, indicating the highest priority node within that country.

Maisem Ali	1ecc16da5f	tailcfg,ipn/ipnlocal,wgengine: add values to PeerCapabilities Define PeerCapabilty and PeerCapMap as the new way of sending down inter-peer capability information. Previously, this was unstructured and you could only send down strings which got too limiting for certain usecases. Instead add the ability to send down raw JSON messages that are opaque to Tailscale but provide the applications to define them however they wish. Also update accessors to use the new values.

Sonia Appasamy	0f5090c526	ipn/ipnlocal: add docs header to serve HTTP proxy Adds a `Tailscale-Headers-Info` header whenever the `Tailscale-User-` headers are filled from the HTTP proxy handler.

Maisem Ali	2ae670eb71	ssh/tailssh: work around lack of scontext in SELinux Trying to SSH when SELinux is enforced results in errors like: ``` ➜ ~ ssh ec2-user@<ip> Last login: Thu Jun 1 22:51:44 from <ip2> ec2-user: no shell: Permission denied Connection to <ip> closed. ``` while the `/var/log/audit/audit.log` has ``` type=AVC msg=audit(1685661291.067:465): avc: denied { transition } for pid=5296 comm="login" path="/usr/bin/bash" dev="nvme0n1p1" ino=2564 scontext=system_u:system_r:unconfined_service_t:s0 tcontext=unconfined_u:unconfined_r:unconfined_t:s0 tclass=process permissive=0 ``` The right fix here would be to somehow install the appropriate context when tailscale is installed on host, but until we figure out a way to do that stop using the `login` cmd in these situations.

These headers only get filled when the SrcAddr is associated with a non-tagged (i.e. user-owned) node within the client's Tailnet.

James Tucker	095d3edd33	ipn/ipnlocal: reenable profile tests on Windows This fix does not seem ideal, but the test infrastructure using a local goos doesn't seem to avoid all of the associated challenges, but is somewhat deeply tied to the setup. The core issue this addresses for now is that when run on Windows there can be no code paths that attempt to use an invalid UID string, which on Windows is described in [1]. For the goos="linux" tests, we now explicitly skip the affected migration code if runtime.GOOS=="windows", and for the Windows test we explicitly use the running users uid, rather than just the string "user1". We also now make the case where a profile exists and has already been migrated a non-error condition toward the outer API.

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).

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.

shayne	7908b6d616	ipn/ipnlocal: [serve] Trim mountPoint prefix from proxy path (#7334 ) This change trims the mountPoint from the request URL path before sending the request to the reverse proxy. Today if you mount a proxy at `/foo` and request to `/foo/bar/baz`, we leak the `mountPoint` `/foo` as part of the request URL's path. This fix makes removed the `mountPoint` prefix from the path so proxied services receive requests as if they were running at the root (`/`) path. This could be an issue if the app generates URLs (in HTML or otherwise) and assumes `/path`. In this case, those URLs will 404. With that, I still think we should trim by default and not leak the `mountPoint` (specific to Tailscale) into whatever app is hosted. If it causes an issue with URL generation, I'd suggest looking at configuring an app-specific path prefix or running Caddy as a more advanced solution.

Mihai Parparita	97b6d3e917	sockstats: remove per-interface stats from Get They're not needed for the sockstats logger, and they're somewhat expensive to return (since they involve the creation of a map per label). We now have a separate GetInterfaces() method that returns them instead (which we can still use in the PeerAPI debug endpoint). If changing sockstatlog to sample at 10,000 Hz (instead of the default of 10Hz), the CPU usage would go up to 59% on a iPhone XS. Removing the per-interface stats drops it to 20% (a no-op implementation of Get that returns a fixed value is 16%).

Maisem Ali	b797f773c7	ipn/ipnlocal: add support for funnel in tsnet Previously the part that handled Funnel connections was not aware of any listeners that tsnet.Servers might have had open so it would check against the ServeConfig and fail. Adding a ServeConfig for a TCP proxy was also not suitable in this scenario as that would mean creating two different listeners and have one forward to the other, which really meant that you could not have funnel and tailnet-only listeners on the same port. This also introduces the ipn.FunnelConn as a way for users to identify whether the call is coming over funnel or not.

However, we can use it to validate the stats that we collect ourselves using read/write hooks, so that we can be more confident in them.

Mihai Parparita	9cb332f0e2	sockstats: instrument networking code paths Uses the hooks added by tailscale/go#45 to instrument the reads and writes on the major code paths that do network I/O in the client. The convention is to use "<package>.<type>:<label>" as the annotation for the responsible code path. Enabled on iOS, macOS and Android only, since mobile platforms are the ones we're most interested in, and we are less sensitive to any throughput degradation due to the per-I/O callback overhead (macOS is also enabled for ease of testing during development). For now just exposed as counters on a /v0/sockstats PeerAPI endpoint. We also keep track of the current interface so that we can break out the stats by interface.

Mihai Parparita	fa932fefe7	net/interfaces: redo how we get the default interface on macOS and iOS With #6566 we added an external mechanism for getting the default interface, and used it on macOS and iOS (see tailscale/corp#8201). The goal was to be able to get the default physical interface even when using an exit node (in which case the routing table would say that the Tailscale utun* interface is the default). However, the external mechanism turns out to be unreliable in some cases, e.g. when multiple cellular interfaces are present/toggled (I have occasionally gotten my phone into a state where it reports the pdp_ip1 interface as the default, even though it can't actually route traffic). It was observed that `ifconfig -v` on macOS reports an "effective interface" for the Tailscale utn* interface, which seems promising. By examining the ifconfig source code, it turns out that this is done via a SIOCGIFDELEGATE ioctl syscall. Though this is a private API, it appears to have been around for a long time (e.g. it's in the 10.13 xnu release at https://opensource.apple.com/source/xnu/xnu-4570.41.2/bsd/net/if_types.h.auto.html) and thus is unlikely to go away. We can thus use this ioctl if the routing table says that a utun* interface is the default, and go back to the simpler mechanism that we had before #6566.

We are seeing some reports of the wrong cellular interface being chosen on iOS. To help with the investigation, this adds to knobs to control the behavior changes: - CapabilityDebugDisableAlternateDefaultRouteInterface disables the alternate function that we use to get the default interface on macOS and iOS (implemented in tailscale/corp#8201). We still log what it would have returned so we can see if it gets things wrong. - CapabilityDebugDisableBindConnToInterface is a bigger hammer that disables binding of connections to the default interface altogether.

Aaron Klotz	659e7837c6	health, ipn/ipnlocal: when -no-logs-no-support is enabled, deny access to tailnets that have network logging enabled We want users to have the freedom to start tailscaled with `-no-logs-no-support`, but that is obviously in direct conflict with tailnets that have network logging enabled. When we detect that condition, we record the issue in health, notify the client, set WantRunning=false, and bail. We clear the item in health when a profile switch occurs, since it is a per-tailnet condition that should not propagate across profiles. Signed-off-by: Aaron Klotz <aaron@tailscale.com>	2 years ago

Brad Fitzpatrick	06c4c47d46	ipn: remove unused Backend interface Only the macOS/iOS clients care about it still, so we'll move it to their repo. But keep a test that makes sure that LocalBackend continues to implement it so we get an early warning sign before we break macOS/iOS.

Brad Fitzpatrick	ea25ef8236	util/set: add new set package for SetHandle type We use this pattern in a number of places (in this repo and elsewhere) and I was about to add a fourth to this repo which was crossing the line. Add this type instead so they're all the same. Also, we have another Set type (SliceSet, which tracks its keys in order) in another repo we can move to this package later.

Brad Fitzpatrick	8049053f86	ipn/*: make new WindowsUserID type to consolidate docs The "userID is empty everywhere but Windows" docs on lots of places but not everywhere while using just a string type was getting confusing. This makes a new type to wrap up those rules, however weird/historical they might be.

Brad Fitzpatrick	5676d201d6	ipn: add a WatchIPNBus option bit to subscribe to EngineStatus changes So GUI clients don't need to poll for it. We still poll internally (for now!) but that's still cheaper. And will get much cheaper later, without having to modify clients once they start sending this bit.
