build: Set FUSE_PREFIX in fuse.cmake

2026-02-18T06:55:59+00:00

The FUSE_PREFIX was set in global.cmake, but before HAVE_FUSE was defined. The FUSE_PREFIX should be set in fuse.cmake. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Add SLH-DSA tests and per-algorithm PQC gating

2026-02-18T06:53:35+00:00

This replaces the single HAVE_OPENSSL_PQC/DISABLE_PQC with per-algorithm CMake variables (ML-KEM, ML-DSA, SLH-DSA), gated by the OpenSSL versions: ML-KEM and ML-DSA require >= 3.4, SLH-DSA >= 3.5. SLH-DSA was already working, but now added explicit authentication tests for it with a full certificate chain (root CA, intermediate CA, server) to show full support. Rename PQC test files and cert headers to use algorithm-specific names (ml_kem, ml_dsa, slh_dsa) and move cert headers to include/test/certs/.

build: Fix clobbering of FUSE_PREFIX

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

pkg_check_modules(FUSE ...) in fuse.cmake tells CMake's pkg-config module to use FUSE as the variable prefix. pkg-config then populates FUSE_PREFIX with the install prefix of libfuse (i.e., usr). This overwrote the FUSE_PREFIX cache variable set to /tmp/ouroboros in global.cmake. IRMd was calling mkdir("/usr", 0777) on startup and rmdir("/usr") on shutdown. The rmdir only fails because usr isn't empty — if it ever were (e.g., in a minimal container), it would deleted /usr. The fix renames the pkg-config prefix from FUSE to FUSE_PKG, so pkg-config populates FUSE_PKG_PREFIX (harmless) instead of clobbering FUSE_PREFIX.

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

lib: Fix OpenSSL includes and explicit_bzero on OSX

2026-02-13T08:22:06+00:00

The include headers and NIDs are different on macOS X. It also doesn't have explicit_bzero. The crypt.h includes are now guarded to work on OS X (trying to avoid the includes by defining the OpenSSL mac header guard led to a whole list of other issues). The explicit zero'ing of buffers temporarily holding secrets has now been abstracted in a crypt_secure_clear() function defaulting to OpenSSL_cleanse, explicit_bzero (if present) or a best-effort option using a volatile pointer.

lib: Fix crypt test and secure memory initialization

2026-01-30T06:56:37+00:00

The crypt_test had a HAVE_OPENSSL guard missing and was trying to execute tests that required OpenSSL without it being installed. The SECMEM values need to be set by CMake without OpenSSL installed. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Add post-quantum cryptography support

2026-01-19T07:29:29+00:00

This adds initial support for runtime-configurable encryption and post-quantum Key Encapsulation Mechanisms (KEMs) and authentication (ML-DSA). Supported key exchange algorithms: ECDH: prime256v1, secp384r1, secp521r1, X25519, X448 Finite Field DH: ffdhe2048, ffdhe3072, ffdhe4096 ML-KEM (FIPS 203): ML-KEM-512, ML-KEM-768, ML-KEM-1024 Hybrid KEMs: X25519MLKEM768, X448MLKEM1024 Supported ciphers: AEAD: aes-128-gcm, aes-192-gcm, aes-256-gcm, chacha20-poly1305 CTR: aes-128-ctr, aes-192-ctr, aes-256-ctr Supported HKDFs: sha256, sha384, sha512, sha3-256, sha3-384, sha3-512, blake2b512, blake2s256 Supported Digests for DSA: sha256, sha384, sha512, sha3-256, sha3-384, sha3-512, blake2b512, blake2s256 PQC support requires OpenSSL 3.4.0+ and is detected automatically via CMake. A DISABLE_PQC option allows building without PQC even when available. KEMs differ from traditional DH in that they require asymmetric roles: one party encapsulates to the other's public key. This creates a coordination problem during simultaneous reconnection attempts. The kem_mode configuration parameter resolves this by pre-assigning roles: kem_mode=server # Server encapsulates (1-RTT, full forward secrecy) kem_mode=client # Client encapsulates (0-RTT, cached server key) The enc.conf file format supports: kex= # Key exchange algorithm cipher= # Symmetric cipher kdf= # Key derivation function digest= # Digest for DSA kem_mode= # Server (default) or client none # Disable encryption The OAP protocol is extended to negotiate algorithms and exchange KEX data. All KEX messages are signed using existing authentication infrastructure for integrity and replay protection. Tests are split into base and _pqc variants to handle conditional PQC compilation (kex_test.c/kex_test_pqc.c, oap_test.c/oap_test_pqc.c). Bumped minimum required OpenSSL version for encryption to 3.0 (required for HKDF API). 1.1.1 is long time EOL. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

build: Add build target to generate coverage report

2026-01-12T07:12:45+00:00

This adds a 'make coverage' option to conveniently summarize test coverage. If lcov is installed, it will also automatically generate the HTML summary. 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
