Review rev_521835488a3c4d71bbc09bc60348519b

{
  "summary": "`aws-lc/crypto/thread_none.c` is a small compile-time threading stub for the non-`OPENSSL_THREADS` build path: it implements mutex no-ops, a one-time init guard, and per-thread storage accessors backed by a static array. I checked it for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.\nReviewed `aws-lc/include/openssl/blowfish.h`, which is a small C header declaring Blowfish constants, a key struct, and deprecated encryption API prototypes. 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 in this file.\nI reviewed `aws-lc/include/openssl/evp_errors.h`, which is a small OpenSSL/AWS-LC error-code header consisting only of `#define` constants for EVP error reasons. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, subprocess launches, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `word_clz.S`, a small x86-64 assembly routine that computes count-leading-zeros via `bsrq` and a zero-input fixup. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `aws-lc/crypto/fipsmodule/cpucap/cpu_aarch64_freebsd.c`, which only probes AArch64 FreeBSD CPU feature registers and sets OpenSSL capability flags during `OPENSSL_cpuid_setup()`. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.",
