为什么我无法在 FreeBSD 12.0-STABLE 设置中使 OCSP Stapling 与 nginx、libressl 一起工作?

为什么我无法在 FreeBSD 12.0-STABLE 设置中使 OCSP Stapling 与 nginx、libressl 一起工作?

经过几个小时的尝试,我必须寻求帮助来解决我的问题。我试图让 OCSP 装订与我的设置配合使用,但没有成功。

这是我的 nginx 配置,没有任何不相关的位。

user www www;
worker_processes 5;
error_log /var/log/nginx/error.log;
events {
    worker_connections 1024;
}

server {

    listen [::]:80;
    listen 443 ssl http2;

    server_name localhost ;
    access_log /var/log/nginx/access.log main;
    root /www/;
    error_page 404 /404.html;

    if ($shouldUpgrade) {
        return 307 https://$host$request_uri;
    }

}
}

我在日志文件中收到一个错误:

2019/04/30 21:28:07 [error] 28718#100839: OCSP_basic_verify() failed (SSL: error:27FFF076:OCSP routines:CRYPTO_internal:signer certificate not found) while requesting certificate status, responder: ocsp.int-x3.letsencrypt.org, peer: 2.16.100.83:80, certificate: "/usr/local/etc/nginx/fullchain.pem"

无论我尝试在提供给 的文件中包括什么ssl_trusted_certificate,我都无法解决这个问题。我尝试包括完整的链,将根 CA 添加到其中,仅 CA,仅中介。将根 CA 添加到提供给 ssl_certificate 的 fullchain.pem 文件中会导致 SSL 验证网站上出现错误。

尽管如此,我仍然OCSP Stapling not enabled.受到https://ssldecoder.orgOCSP response: no response sent使用 openssl s_client时

任何帮助都将不胜感激。我正在使用 let's encrypt。

FreeBSD security/libressl 最近升级到了 2.9.1。自从 LibreSSL 版本更改以来,OCSP 装订功能也停止在 nginx 中工作,因此我假设库或 nginx 与它的交互中存在潜在问题。

编辑: 同时,Elias Ohm 在 FreeBSD 错误跟踪器上对此进行了更详细的分析。TL;DR:这是一个 nginx 错误,在使用较新的 OpenSSL API 时,它使用了错误的函数来访问证书链。
