chomium正在使用NSS或BoringSSL

Question

Linux上的铬是否仍使用Nss而不是Boringssl？我已经检查了下面的代码 net / cert / cert_verify_proc.cc

#if defined(USE_NSS_CERTS)
    return new CertVerifyProcNSS();
#elif defined(OS_ANDROID)
    return new CertVerifyProcAndroid(std::move(cert_net_fetcher));
#elif defined(OS_IOS)
    return new CertVerifyProcIOS();
#elif defined(OS_MACOSX)
    return new CertVerifyProcMac();
#elif defined(OS_WIN)
    return new CertVerifyProcWin();
#elif defined(OS_FUCHSIA)
    return CreateCertVerifyProcBuiltin(
        std::move(cert_net_fetcher),
        SystemTrustStoreProvider::CreateDefaultForSSL());
#else
    #error Unsupported platform
#endif

所以Linux下只有Nss可用，对吧？
