Aaron Klotz	7132b782d4	hostinfo: use Distro field for distinguishing Windows Server builds Some editions of Windows server share the same build number as their client counterpart; we must use an additional field found in the OS version information to distinguish between them. Even though "Distro" has Linux connotations, it is the most appropriate hostinfo field. What is Windows Server if not an alternate distribution of Windows? This PR populates Distro with "Server" when applicable. Fixes #11785 Signed-off-by: Aaron Klotz <aaron@tailscale.com>	7 months ago

Joe Tsai	7a77a2edf1	logtail: optimize JSON processing (#11671 ) Changes made: * Avoid "encoding/json" for JSON processing, and instead use "github.com/go-json-experiment/json/jsontext". Use jsontext.Value.IsValid for validation, which is much faster. Use jsontext.AppendQuote instead of our own JSON escaping. * In drainPending, use a different maxLen depending on lowMem. In lowMem mode, it is better to perform multiple uploads than it is to construct a large body that OOMs the process. * In drainPending, if an error is encountered draining, construct an error message in the logtail JSON format rather than something that is invalid JSON. * In appendTextOrJSONLocked, use jsontext.Decoder to check whether the input is a valid JSON object. This is faster than the previous approach of unmarshaling into map[string]any and then re-marshaling that data structure. This is especially beneficial for network flow logging, which produces relatively large JSON objects. * In appendTextOrJSONLocked, enforce maxSize on the input. If too large, then we may end up in a situation where the logs can never be uploaded because it exceeds the maximum body size that the Tailscale logs service accepts. * Use "tailscale.com/util/truncate" to properly truncate a string on valid UTF-8 boundaries. * In general, remove unnecessary spaces in JSON output.

Joe Tsai	85febda86d	all: use zstdframe where sensible (#11491 ) Use the zstdframe package where sensible instead of plumbing around our own zstd.Encoder just for stateless operations. This causes logtail to have a dependency on zstd, but that's arguably okay since zstd support is implicit to the protocol between a client and the logging service. Also, virtually every caller to logger.NewLogger was manually setting up a zstd.Encoder anyways, meaning that zstd was functionally always a dependency.

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.

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.

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.
