ошибка cURL 35: сбой gnutls_handshake()

Я получаю следующую ошибку от компонента PHP, который использует CURL для запроса URI через SSL:

cURL error 35: gnutls_handshake() failed: A TLS packet with unexpected length was received.

Эта ошибка возникает в среде travis-ci.org, но не в любой из наших тестовых сред. См. сборку travis-ci 144663700.

Я обнаружил, что версия PHP, работающая в рабочей среде Travis, снова скомпилирована «GnuTLS/2.12.14» на «Ubuntu 12.04.5 LTS» или с «GnuTLS/2.12.23» на «Ubuntu 14.04.3 LTS».

В наших средах разработки мы используем стандартные пакеты, скомпилированные для «OpenSSL/1.0.1t» в Debian (различные версии).

Поэтому я предполагаю, что проблема связана с "GnuTLS/2.12.14" или "GnuTLS/2.12.23" или с параметрами, с которыми они были скомпилированы.

Я попытался ограничить версии SSL константой CURL CURLOPT_SSLVERSION, но это не решает проблему.

Согласно www.ssllabs.com, рассматриваемый хост — api.reporting.cloud — поддерживает TLS 1.2, TLS 1.1 и TLS 1.0.

У кого-нибудь есть какие-нибудь подсказки или указатели для меня?

Обходной путь для этой проблемы — настроить travis-ci на использование стандартных пакетов Ubuntu Trusty php5-cli и php5-curl. Стандартные пакеты предлагают константу CURL_SSLVERSION_TLSv1_1.

Файл .travis.yml выглядит так:

sudo: required

dist: trusty

language: php

before_install:
  - sudo apt-get -y install git zip php5-cli php5-curl

before_script:
  - php -r "printf('PHP %s', phpversion());"
  - composer self-update
  - composer install --no-interaction

script:
  - mkdir -p ./build/logs
  - ./vendor/bin/phpunit

В исходном коде PHP это просто вопрос установки вышеупомянутой константы в случае, если код PHP выполняется travis-ci:

if (getenv('TRAVIS')) {
    $options['curl'][CURLOPT_SSLVERSION] = CURL_SSLVERSION_TLSv1_1;
}

Этот обходной путь имеет тот недостаток, что он работает только с конкретной версией PHP, которую предлагает Ubuntu Trusty (PHP 5.5). Учитывая, что срок службы PHP 5.5 истек 10 июля 2016 г., это решение неприемлемо.

Было бы идеально, если бы travis-ci обновился до Ubuntu 16.04 LTS, но Брэндон Бертон, менеджер инфраструктуры travis-ci написал 28 февраля 2016 г.:

Учитывая это, в настоящее время мы сосредоточены на поддержке 12.04 и 14.04 в качестве наших основных сред. На данный момент маловероятно, что в этом году мы будем поддерживать 16.04 в качестве родной среды.

Поэтому, похоже, мы на какое-то время застряли с Ubuntu Trusty.

Корень этой проблемы в том, что версия PHP, работающая на travis-ci, была скомпилирована с gnutls-cli (GnuTLS) 2.12.23 от 2011 года. Эта конкретная версия gnutls-cli имеет проблемы с некоторыми (но не со всеми) TLS 1.2. связи.

@travis-ci: Можно ли перекомпилировать версии PHP, которые вы используете, с более современной версией GnuTLS или, по крайней мере, с той, которая лучше поддерживает TLS 1.2?

к сожалению, Ubuntu 16.04 также страдает от этой проблемы. - person RAM; 07.11.2018

В PHP можно управлять протоколом SSL, который использует curl, с помощью констант CURL_SSLVERSION_*.

Установив:

curl_setopt($ch, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1_1);

Я могу заставить curl использовать «TLS 1.1».

Установив:

curl_setopt($ch, CURLOPT_SSLVERSION, CURL_SSLVERSION_TLSv1);

Я могу заставить curl использовать «TLS 1.0».

Чтобы протестировать все возможные протоколы SSL, я создал следующий скрипт, который затем выполняется travis-ci:

<?php

$sslVersions = [
    CURL_SSLVERSION_DEFAULT,
    CURL_SSLVERSION_TLSv1,
    CURL_SSLVERSION_TLSv1_0,
    CURL_SSLVERSION_TLSv1_1,
    CURL_SSLVERSION_TLSv1_2,
    CURL_SSLVERSION_SSLv2,
    CURL_SSLVERSION_SSLv3,
];

var_dump(curl_version());

foreach ($sslVersions as $sslVersion) {

    $uri = "https://api.reporting.cloud";

    printf("Trying %d", $sslVersion);
    echo PHP_EOL;

    $ch = curl_init($uri);

    curl_setopt($ch, CURLOPT_VERBOSE        , true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER , 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT , 0);
    curl_setopt($ch, CURLOPT_TIMEOUT        , 2);
    curl_setopt($ch, CURLOPT_SSLVERSION     , $sslVersion);

    if (curl_exec($ch) === false) {
        var_dump(curl_error($ch));
    } else {
        curl_close($ch);
    }

    echo PHP_EOL;
    echo PHP_EOL;

}

exit(1);

Вывод этого скрипта в моих средах разработки:

Я также заметил, что константы CURL_SSLVERSION_TLSv1_0, CURL_SSLVERSION_TLSv1_1 и CURL_SSLVERSION_TLSv1_2 недоступны в версиях travis-ci PHP 5.6 и PHP 7.

Подводя итог, я перебрал все возможные константы CURL_SSLVERSION_*, и ни одна из них не позволяет мне подключиться к api.reporting.cloud на travis-ci, независимо от того, какую версию PHP я использую.

Есть ли у кого-нибудь предложения о том, как я могу подключиться к api.reporting.cloud из travis-ci?
