include: Suppress coredumpctl entries for tests

2026-03-02T07:28:12+00:00

With DISABLE_TESTS_CORE_DUMPS, setrlimit(RLIMIT_CORE, 0) only prevents core dump files from being written, but when systemd-coredump is configured as a piped handler (via core_pattern), the kernel still invokes it regardless of RLIMIT_CORE, so entries appear in coredumpctl. Adding prctl(PR_SET_DUMPABLE, 0) marks the process as non-dumpable, which prevents the kernel from invoking the core dump handler entirely — including piped ones.

build: Add DISABLE_TESTS_CORE_DUMPS option

2026-01-26T06:48:26+00:00

We have a few that test that assertions are triggered. This adds a DISABLE_TESTS_CORE_DUMPS CMake build option (default ON) that disables core dumps for tests so they don't pollute the core cache. 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
