Brad Fitzpatrick	69f4b4595a	wgengine{,/wgint}: add wgint.Peer wrapper type, add to wgengine.Engine This adds a method to wgengine.Engine and plumbed down into magicsock to add a way to get a type-safe Tailscale-safe wrapper around a wireguard-go device.Peer that only exposes methods that are safe for Tailscale to use internally. It also removes HandshakeAttempts from PeerStatusLite that was just added as it wasn't needed yet and is now accessible ala cart as needed from the Peer type accessor. None of this is used yet.

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.

Percy Wegmann	50fb8b9123	tailfs: replace webdavfs with reverse proxies Instead of modeling remote WebDAV servers as actual webdav.FS instances, we now just proxy traffic to them. This not only simplifies the code, but it also allows WebDAV locking to work correctly by making sure locks are handled by the servers that need to (i.e. the ones actually serving the files).

James Tucker	24bac27632	util/rands: add Shuffle and Perm functions with on-stack RNG state The new math/rand/v2 package includes an m-local global random number generator that can not be reseeded by the user, which is suitable for most uses without the RNG pools we have in a number of areas of the code base. The new API still does not have an allocation-free way of performing a seeded operations, due to the long term compiler bug around interface parameter escapes, and the Source interface. This change introduces the two APIs that math/rand/v2 can not yet replace efficiently: seeded Perm() and Shuffle() operations. This implementation chooses to use the PCG random source from math/rand/v2, as with sufficient compiler optimization, this source should boil down to only two on-stack registers for random state under ideal conditions.

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.
