问题描述

在验证OTA功能过程中，通过升级包制作脚本制作了升级包并部署在下载服务器，OTA应用在下载了全量升级包后，重启进入updater模式进行升级，显示升级失败，升级失败时升级进度条进度没有前进。

验证版本

OpenHarmony 4.0 Beta2

预置条件

开发板烧录项目最新版本代码
开发板连接能够访问下载服务器的网络
开发板上运行搜包程序

测试步骤

解锁开发板进入桌面
点击桌面的软件更新应用
在检查到更新版本后点击下载新版本
下载完成后点击现在安装

问题分析

根据重启开发板后/data/updater/log/updater_log文件中的日志，定位到首次出错位置为memcmp failed。

通过log日志定位到对应代码。

函数VerifyPackageSign在25行调用HashCheck函数。

int32_t PkgVerifyUtil::VerifyPackageSign(const PkgStreamPtr pkgStream) const
{
    if (pkgStream == nullptr) {
        UPDATER_LAST_WORD(PKG_INVALID_PARAM);
        return PKG_INVALID_PARAM;
    }
    size_t signatureSize = 0;
    std::vector<uint8_t> signature;
    uint16_t commentTotalLenAll = 0;
    if (GetSignature(pkgStream, signatureSize, signature, commentTotalLenAll) != PKG_SUCCESS) {
        PKG_LOGE("get package signature fail!");
        UPDATER_LAST_WORD(PKG_INVALID_SIGNATURE);
        return PKG_INVALID_SIGNATURE;
    }

    std::vector<uint8_t> hash;
    int32_t ret = Pkcs7verify(signature, hash);
    if (ret != PKG_SUCCESS) {
        PKG_LOGE("pkcs7 verify fail!");
        UPDATER_LAST_WORD(ret);
        return ret;
    }
    size_t srcDataLen = pkgStream->GetFileLength() - commentTotalLenAll - 2;

    ret =  HashCheck(pkgStream, srcDataLen, hash);
    if (ret != PKG_SUCCESS) {
        srcDataLen = pkgStream->GetFileLength() - signatureSize - ZIP_EOCD_FIXED_PART_LEN;
        ret = HashCheck(pkgStream, srcDataLen, hash);
    }
    return ret;
}

HashCheck函数在24行执行出错。

int32_t PkgVerifyUtil::HashCheck(const PkgStreamPtr srcData, const size_t dataLen,
    const std::vector<uint8_t> &hash) const
{
    Updater::UPDATER_INIT_RECORD;
    if (srcData == nullptr || dataLen == 0) {
        UPDATER_LAST_WORD(PKG_INVALID_PARAM);
        return PKG_INVALID_PARAM;
    }

    size_t digestLen = hash.size();
    if (digestLen != PKG_HASH_CONTENT_LEN) {
        PKG_LOGE("calc pkg sha256 digest failed.");
        UPDATER_LAST_WORD(PKG_INVALID_PARAM);
        return PKG_INVALID_PARAM;
    }
    std::vector<uint8_t> sourceDigest(digestLen);
    int32_t ret = CalcSha256Digest(srcData, dataLen, sourceDigest);
    if (ret != PKG_SUCCESS) {
        PKG_LOGE("calc pkg sha256 digest failed.");
        UPDATER_LAST_WORD(ret);
        return ret;
    }

    if (memcmp(hash.data(), sourceDigest.data(), digestLen) != EOK) {
        PKG_LOGE("calculated hash: %s, respond hash: %s", hash.data(), sourceDigest.data());
        PKG_LOGE("Failed to memcmp data.");
        UPDATER_LAST_WORD(PKG_INVALID_DIGEST);
        return PKG_INVALID_DIGEST;
    }

    return PKG_SUCCESS;
}

据此推测升级失败直接原因为计算出的升级包摘要值不符合程序要求。

确认下载到开发板内的升级包md5值。

开发板内计算升级包摘要值。

# md5sum updater_full.zip
ea09dae7b0f21b4eab61052fb9d3ee5a  updater_full.zip

主机计算升级包摘要值。

PS> openssl md5 updater_full.zip
MD5(.\updater_full.zip)= ea09dae7b0f21b4eab61052fb9d3ee5a

确定摘要值相同。

确认签名升级包的证书已经传入开发板。

PS> hdc file send signing_cert.crt /data/update/ota_package/

制作升级包时updater_config文件夹中文件的内容。
