Review rev_47144376e32243e9bd6f2f74db77632c

{
  "summary": "Reviewed `aws-lc/crypto/ube/fork_ube_detect_test.cc`, a Linux-only gtest that forks child and grandchild processes to verify fork-generation tracking and thread safety. I found no concrete malicious or supply-chain indicators in the file: no install hooks, network/exfiltration, credential access, hidden downloads, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/x509/v3_ocsp.c`, which implements OCSP/X.509 extension handlers for ASN.1 generalized time, OCSP nonce, and OCSP noCheck encoding/printing. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found no concrete malicious behavior in this file.\nReviewed the generated x86 NASM trampoline used for AWS-LC ABI tests. It contains only register-save/restore helpers, flag toggles, and clobber routines; I found no install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain indicators in this file.\nReviewed this x86 jitterentropy helper header, which provides inline timing, allocation, cache-sizing, and yield utilities for entropy collection. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in the target file.\nReviewed the x86-64 assembly implementation of `bignum_emontredc`, which performs in-place extended Montgomery reduction with standard ABI handling and register save/restore. I found no concrete malicious indicators: there are no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior in this target file.",
