lib: Harden symmetric-key rotation

2026-06-29T06:32:58+00:00

Flow crypto signalled rotation with a single phase-parity bit, so a loss burst that hid an even number of rotations went unnoticed and wedged the flow for good. Each packet now carries a small cleartext selector naming its key directly, so a receiver that falls behind recovers on the next packet instead of getting stuck. The selector also serves as the AEAD nonce and is authenticated as associated data (AAD). Key rotation moves into a new backend-agnostic keyrot module that rotates sub-keys to bound AEAD usage while preserving forward secrecy.

lib: Add generic hierarchical timing wheel

2026-05-20T06:17:06+00:00

Introduce a generic 3-level / 256-slot deadline-ordered callback queue (1 ms / 16 ms / 256 ms per-slot resolution at levels 0/1/2). Will replace the existing timerwheel.c. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Add CRC-8 and CRC-16 checksums

2026-05-06T07:04:48+00:00

These checksum will be handy for header checksums. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Add CRC-64/NVMe checksum

2026-05-06T07:04:41+00:00

Add CRC-64/NVMe implementation with compile-time hardware backend selection: x86 PCLMUL+SSE4.1 fold-by-16 (HAVE_PCLMUL) aarch64 PMULL fold-by-16 when (HAVE_PMULL) and a byte-table fallback. It's added as HASH_CRC64 to enum hash_algo (in the internal-use-only section after HASH_MD5). Both mem_hash() and hash_len() early-return for HASH_CRC64 because libgcrypt has no CRC-64/NVMe.

lib: Add struct llist for lists tracking len

2026-02-18T06:58:21+00:00

The DHT uses a struct {struct list_head, size_t len} pattern, which is also useful in the registry and other places. Having a struct llist (defined in list.h) with consistent macros for addition/deletion etc removes a lot of duplication and boilerplate and reduces the risk of inconsistent updates. The list management is now a macro-only implementation. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Refactor CMake back to in-tree CMakeLists

2026-02-13T08:22:29+00:00

This moves the build definitions back to src/ subdirectories (CMakeLists.txt per component). Configuration and dependencies are kept out of tree. Configuration options are bundled into cmake/config/ modules. Dependencies are grouped by component (system/, crypt/, eth/, coverage/, etc.). It now consistently uses target-based commands (target_include_directories, target_link_libraries) instead of global include_directories(). Proper PRIVATE/PUBLIC visibility for executable link libraries. CONFIG_OUROBOROS_DEBUG now properly set based on being a valid debug config (not just checking the string name). It also adds OuroborosTargets export for find_package() support and CMake package config files (OuroborosConfig.cmake) for easier integration with CMake projects. The build logic now follows more idiomatic CMake practices with configuration separated from target definitions. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Refactor CMake modules

2026-01-07T09:00:06+00:00

This moves the CMake build logic out of the source tree and splits it up into a more modular form. The tests now have a CMakeLists.txt file in their respective source directory. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Only add tests when BUILD_TESTING is ON

2025-11-07T07:35:48+00:00

By default, BUILD_TESTING = ON due to the inclusion of the CTest module. Signed-off-by: Thijs Paelman Signed-off-by: Sander Vrijders

irmd: Initial Flow Allocation Protocol Header

2025-07-23T13:07:52+00:00

This adds the initial version for the flow allocation protocol header between IRMd instances. This is a step towards flow authentication. The header supports secure and authenticated flow allocation, supporting certificate-based authentication and ephemeral key exchange for end-to-end encryption. id: 128-bit identifier for the entity. timestamp: 64-bit timestamp (replay protection). certificate: Certificate for authentication. public key: ECDHE public key for key exchange. data: Application data. signature: Signature for integrity/authenticity. Authentication and encryption require OpenSSL to be installed. The IRMd compares the allocation request delay with the MPL of the Layer over which the flow allocation was sent. MPL is now reported by the Layer in ms instead of seconds. Time functions revised for consistency and adds some tests. The TPM can now print thread running times in Debug builds (TPM_DEBUG_REPORT_INTERVAL) and abort processes with hung threads (TPM_DEBUG_ABORT_TIMEOUT). Long running threads waiting for input should call tpm_wait_work() to avoid trigger a process abort. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
