The gnutls bbappend builds GnuTLS with --enable-ktls and installs /etc/gnutls/config with ktls = true, so after the handshake the kernel seals and opens forgectrl's HTTPS records (the kernel side is meta-openglow's CONFIG_TLS and patch 0016). It also backports GnuTLS dc016daf: 3.8.4 hands the kernel the record sequence number where a TLS 1.2 ChaCha20-Poly1305 connection's IV belongs, so every such connection failed the kernel's first decryption. forgectrl is the only program on the image that links GnuTLS. forgectrl.tls-records, in its own module (suite/tlsrec.py), reads the result from the outside with openssl s_client on loopback: a desktop offer (AES-GCM first) gets ChaCha20-Poly1305 over TLS 1.3 and 1.2 and the kernel takes both directions' keys; an AES-128-GCM-only offer, three times over each protocol, gets it, the kernel takes its keys, and the CAAM's job-ring interrupt counts the records; a TLS 1.2 CBC-only offer connects and stays in GnuTLS (the control for the kernel's counters); every copy of the panel page equals the plain-HTTP copy byte for byte, with no decrypt error; the kernel's drivers are rfc7539(chacha20-neon,poly1305-neon) and ctr-aes-caam with ghash-ce. Proof: on the image before these fixes the test failed on both bugs it names (the TLS 1.2 ChaCha20 page arrived empty with a decrypt error; the AES-GCM pages arrived damaged); on image 20260927224418 it passes. The unit suite (500 tests) and the coverage lint (0 uncovered paths) pass on the host.
