Review rev_4ba2dc797305458a929b9bf14a9aa2f8

{
  "summary": "Reviewed `aws-lc/crypto/rand_extra/entropy_passive.c`, which is a small conditional entropy helper that zero-initializes a local buffer, calls `CRYPTO_get_seed_entropy`, and forwards the result to `RAND_load_entropy` when `FIPS_ENTROPY_SOURCE_PASSIVE` is enabled. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed `aws-lc/include/openssl/dtls1.h`, which is only a short compatibility/license header for OpenSSL-style builds and contains no executable code, install hooks, network/exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior. I found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/include/openssl/is_awslc.h`, which is only a short license/comment header stating it exists to catch include path errors in consuming AWS-LC. I found no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other executable behavior in this file.\nReviewed `aws-lc/include/openssl/safestack.h`, which is only a short copyright/license compatibility header explaining that it exists to ease OpenSSL-compatible builds. I checked for install hooks, hidden execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed a small C test program that compares a fixed local buffer with `memcmp` and prints the result to detect a known compiler bug. I checked for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.",
