  "message": "Fix ASAN error revealed by a new fuzz test.\n\nThe QUIC-LB spec allows nonce lengths of 18 bytes, although this is an extreme case. For convenience, the LoadBalancerEncoder implementation limits it to 16 bytes so that it fits in a 128-bit integer.\n\nThe fuzz test revealed that if the nonce is 16 bytes long, the code that confines the 128-bit integer to the configured length has a bit overflow (i.e. 1 \u003c\u003c 128 is out of range).\n\nIn the refactoring to fix this, the code switches from starting the nonce at seed_ and decrementing, and instead incrementing. One test of multiple consecutive connection IDs therefore has to change.\n\nThis part of the code is not in production. Even when QUIC-LB is deployed, we will not use 16 byte nonces. Nevertheless, the OSS implementation should be as flexible as possible.\n\nPiperOrigin-RevId: 963480631\n",
