feat(machine id): Add helpers in ddcommon to fetch the machine UUID l… by paullegranddc · Pull Request #2163 · DataDog/libdatadog

…ike the agent

Motivation

We are replicating the agent RC client. One of the thing the agent uses is a stable identity for the agent host, decorrelated from the hostname (as it is not available in som platforms).

It fetches the UUID using a library (psutils), for which there exists no strict equivalent in rust.

This PR adds code that should be feature equal to the agent

Changes

Add new machine_id module in libdd-common
Fetch machine id on different platform

error[vulnerability]: NSEC3 closest-encloser proof validation enters unbounded loop on cross-zone responses

   ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0118
   ├ The NSEC3 closest-encloser proof validation in `hickory-proto`'s
     `DnssecDnsHandle` walks from the QNAME up to the SOA owner name, building a
     list of candidate encloser names. The iterator used assumes the
     QNAME is a descendant of the SOA owner, terminating only when the current
     candidate equals the SOA name. When the SOA in a response's authority section
     is not an ancestor of the QNAME, the loop stalls at the DNS root and never
     terminates, repeatedly calling `Name::base_name()` and pushing newly allocated
     `Name` and hashed-name entries into the candidate `Vec`.
     
     The bug is reachable by any caller of `DnssecDnsHandle` — including the
     resolver, recursor, and client — when built with the `dnssec-ring` or
     `dnssec-aws-lc-rs` feature and configured to perform DNSSEC validation. It is
     triggered while validating a NoData or NXDomain response whose authority
     section contains an SOA record from a zone other than an ancestor of the
     QNAME, on a code path that requires NSEC3 closest-encloser proof. In practice
     this can be reached through an insecure CNAME chain that crosses zone
     boundaries into a DNSSEC-signed zone returning NoData, but the minimum
     condition is just a mismatched SOA owner on a response requiring NSEC3
     validation.
     
     A `debug_assert_ne!(name, Name::root())` guards the loop body, so debug builds
     abort with a panic on the first iteration past the root. Release builds
     compile the assertion out and run the loop unbounded, allocating until the
     process exhausts available memory (OOM). A reachable upstream attacker who
     can return such a response can therefore crash a debug-built validator or
     exhaust memory on a release-built one.
     
     The affected code was migrated from `hickory-proto` to `hickory-net` as part of
     the 0.26.0 release. The `hickory-proto` 0.26.x release no longer offers
     `DnssecDnsHandle` and so we recommend all affected users update to `hickory-net`
     0.26.1 when the implementation of that type is required.

   ├ Advisory: https://rustsec.org/advisories/RUSTSEC-2026-0119
   ├ During message encoding, `hickory-proto`'s `BinEncoder` stores pointers to
     labels that are candidates for name compression in a `Vec<(usize, Vec<u8>)>`.
     The name compression logic then searches for matches with a linear scan.
     
     A malicious message with many records can both introduce many candidate labels,
     and invoke this linear scan many times. This can amplify CPU exhaustion in DoS
     attacks.

    ├ It has been reported (by @lopopolo) that the `rand` library is [unsound](https://rust-lang.github.io/unsafe-code-guidelines/glossary.html#soundness-of-code--of-a-library) (i.e. that safe code using the public API can cause Undefined Behaviour) when all the following conditions are met:
      
      - The `log` and `thread_rng` features are enabled
      - A [custom logger](https://docs.rs/log/latest/log/#implementing-a-logger) is defined
      - The custom logger accesses `rand::rng()` (previously `rand::thread_rng()`) and calls any `TryRng` (previously `RngCore`) methods on `ThreadRng`
      - The `ThreadRng` (attempts to) reseed while called from the custom logger (this happens every 64 kB of generated data)
      - Trace-level logging is enabled or warn-level logging is enabled and the random source (the `getrandom` crate) is unable to provide a new seed
      
      `TryRng` (previously `RngCore`) methods for `ThreadRng` use `unsafe` code to cast `*mut BlockRng<ReseedingCore>` to `&mut BlockRng<ReseedingCore>`. When all the above conditions are met this results in an aliased mutable reference, violating the Stacked Borrows rules. Miri is able to detect this violation in sample code. Since construction of [aliased mutable references is Undefined Behaviour](https://doc.rust-lang.org/stable/nomicon/references.html), the behaviour of optimized builds is hard to predict.

Keep Windows status comparisons in u32

On Windows this module fails to type-check because windows-sys 0.52 defines RegOpenKeyExW/RegQueryValueExW as returning WIN32_ERROR (u32), but these checks compare that u32 to ERROR_SUCCESS as i32. Any Windows build of libdd-common that includes this new module will fail before use; compare against ERROR_SUCCESS without the cast here and in the two RegQueryValueExW status checks.

Useful? React with 👍 / 👎.

nit: Do you need is_wow64()? The agent always does KEY_READ_ | KEY_WOW64_64KEY Won't KEY_WOW64_64KEY be a no-op on 64-bit?

Yeah, probably not necessary. I got confused by microsoft doc and claude got defensive

#2163) …ike the agent # Motivation We are replicating the agent RC client. One of the thing the agent uses is a stable identity for the agent host, decorrelated from the hostname (as it is not available in som platforms). It fetches the UUID using a library (psutils), for which there exists no strict equivalent in rust. This PR adds code that should be feature equal to the agent # Changes * Add new machine_id module in libdd-common * Fetch machine id on different platform # What does this PR do? A brief description of the change being made with this pull request. # Motivation What inspired you to submit this pull request? # Additional Notes Anything else we should know when reviewing? # How to test the change?
