oap: Rename kex_config loaders to sec_config

2026-06-29T06:33:00+00:00

Leftover from the kex_config->enc_config->sec_config rename. Finished by renames load_kex_config and the cli/srv variants to load_sec_config, the kcfg variables to scfg, and fixes the "KEX config"/"encryption config" comments. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Harden OAP handshake and add cert-less re-key

2026-06-29T06:33:00+00:00

Adds support for: Server key confirmation: the session key is bound to the negotiated algorithm via the HKDF info. The server returns a key-confirmation tag (rsp_tag, replacing the bare request-hash echo), so a cipher downgrade or key desync is detected. The cleartext path keeps a request echo, compared in constant time. Sealed server identity: AEAD-seal the certificate, signature and piggybacked data in the encrypted response (kex and rsp_tag move ahead as AAD), hiding the server identity and response sizes. Cert-less re-key: let the client omit its certificate, verifying the peer against the cached certificate. On PQC flows, ephemeral server-encap KEX (preserving forward secrecy) is used, even if the original flow allocation was client-encap. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

lib: Group sec_config authentication fields

2026-06-29T06:32:59+00:00

Nest the flat req_auth and cacert members of struct sec_config into a sub-struct a { req; cacert; }, keeping the authentication settings together. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Bound the OAP replay cache

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

Replace the linked-list cache with three timestamp-generation hash buckets, each capped at OAP_REPLAY_MAX entries. A bucket is an open-addressed hash set whose slots count as live only while slot.gen equals the bucket generation, so a stale bucket clears in O(1) by bumping its generation instead of being scanned and pruned. On overflow the cache fails closed - it rejects the header rather than evicting the oldest entry. Under flood, dropping a genuine entry would let that header be replayed, so refusing new entries is the safer degradation than evict-oldest (fail-open) behaviour.

irmd: Add issuer and digest pinning to OAP

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

A peer certificate that verifies against the CA store could have been issued by any trusted CA, and a peer could pick any supported digest for its signature. Tighten the authentication contract with two local policies. cacert= pins the issuing CA: a peer certificate, if presented, must chain through the pinned CA. Whether a certificate is mandatory at all remains controlled by auth= alone. digest= now also pins the signature digest: a classical peer must sign with the locally configured digest, and may not omit the digest NID to fall back to the key's default digest. PQC signatures (ML-DSA, SLH-DSA) have an intrinsic digest and may be NID_undef. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Specify peer authentication contract

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

OAP accepted requests and responses without a certificate even when the peer was expected to authenticate. An on-path attacker could strip the certificate and signature from a flow allocation response and substitute its own key exchange, silently downgrading the handshake to unauthenticated. Add an auth=required|optional policy to enc.conf, enforced per role: a client config requires the server to present a valid certificate, a server config requires the same from the client. Default is required for client side (https), optional server side. The client side default can be changed via OAP_CLIENT_AUTH_DEFAULT for testing. Replace the bare 'none' keyword with encryption=none, which disables encryption only: the digest and the authentication policy are kept, so authenticated but unencrypted flows can be configured. Configs using bare 'none' are now rejected. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders

irmd: Drop replayed flow alloc requests

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

A duplicating link could deliver the same alloc request twice. OAP detected the replay but still replied over the wire, so the requester saw a second flow_alloc_reply on an already-allocated flow and reg_respond_alloc tripped its PENDING-state assertion. Add EREPLAY so the OAP server can signal replays distinctly; flow_accept drops them silently. As a safety net, reg_respond_alloc warn-drops late replies instead of asserting.

lib: Fix missing cleanup in authentication path

2026-03-14T10:23:24+00:00

When auth_verify_crt fails (e.g., missing root CA), crypt_get_pubkey_crt has already allocated pk but only crt was freed. Adds a crypt_cleanup() function to wrap OpenSSL_cleanup(), as OpenSSL lazily initializes a global decoder/provider registry the first time PEM_read_bio or OSSL_DECODER_CTX_new_for_pkey is called, and this leaves some memory owned by OpenSSL that triggers the leak sanitizer.

lib: Add tests for missing root CA

2026-03-14T10:23:18+00:00

This adds authentication tests to verify flows are rejected with a missing root CA certificate in the store. Also adds one for the OAP protocol. Signed-off-by: Dimitri Staessens Signed-off-by: Sander Vrijders
