From 537f598ea30a489219c7b7471b59c170f0a06fb2 Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Fri, 6 Mar 2026 04:27:14 +0000 Subject: [PATCH 1/4] Move imix configuration variables out of pb crate into imix Moved `config.rs` from `implants/lib/pb/src/` to `implants/imix/src/config/mod.rs` to break the dependency cycle where pb contained logic tied specifically to the imix agent. Refactored build scripts to process config logic inside the imix build.rs and leave pb build.rs handling only IMIX_SERVER_PUBKEY configuration needed by its `xchacha` library. Updated references in `transport` library to avoid depending on the config file from imix and to instead receive `pb::c2::Transport` definitions directly, and updated imix agent to extract and provide these representations properly. Cleaned up test configurations around the modified transport APIs.

Refactored build scripts to process config logic inside the imix build.rs and leave pb build.rs handling only IMIX_SERVER_PUBKEY configuration needed by its `xchacha` library. Updated references in `transport` library to avoid depending on the config file from imix and to instead receive `pb::c2::Transport` definitions directly, and updated imix agent to extract and provide these representations properly. Cleaned up test configurations around the modified transport APIs.
