有人研究过更新android系统中的openssl版本么？

[markzune]

android4.4系统中自动的openssl版本是1.0.1e, 而且这个版本存在安全漏洞，客户要求升级android系统中的openssl版本， 我看了下external/openssl下面的 README.android, 有些没看懂， 不知道有没有大侠弄过。

OpenSSL on the Android platform.
---

The code in this directory is based on $OPENSSL_VERSION in the file
openssl.version. See patches/README for more information on how the
code differs from $OPENSSL_VERSION.

Porting New Versions of OpenSSL.
--

The following steps are recommended for porting new OpenSSL versions.

1) Retrieve the appropriate version of the OpenSSL source from
www.openssl.org/source (in openssl-*.tar.gz file). Check the PGP
signature (found in matching openssl-*.tar.gz.asc file) with:

gpg openssl-*.tar.gz.asc

If the public key is not found, import the the one with the
matching RSA key ID from http://www.openssl.org/about/, using:

gpg --import # paste PGP public key block on stdin

2) Update the variables in openssl.config and openssl.version as appropriate.
At the very least you will need to update the openssl.version.

3) Run:

./import_openssl.sh import openssl-*.tar.gz

4) If there are any errors, then modify openssl.config, openssl.version
and patches in patches/ as appropriate. You might want to use:

./import_openssl.sh regenerate patches/*.patch

Repeat step 3.

5) Cleanup before building with:

m -j16 clean-libcrypto clean-libssl clean-openssl clean-ssltest

6) Build openssl from the external/openssl directory with:

mm -j16 snod && adb remount && adb sync system

If there are build errors, then patches/*.mk, openssl.config, or
android-config.mk may need updating.

7) Run tests to make sure things are working:

# Run local openssl tests
(cd android.testssl/ && ./testssl.sh)
# Build and sync libcore tests
(croot && cd libcore && mm -j16 snod && adb remount && adb sync)
# Run tests from libcore
(croot && vogar --classpath out/target/common/obj/JAVA_LIBRARIES/core-tests_intermediates/classes.jar javax.net.ssl tests.api.javax.net)
# Run tests from Harmony
(croot && vogar --classpath out/target/common/obj/JAVA_LIBRARIES/apache-harmony-tests_intermediates/classes.jar tests.api.java.math.BigIntegerTest org.apache.harmony.tests.java.math)
# try an https website
adb shell am start https://online.citibank.com # confirm result in browser

The vogar tool can be found externally at http://code.google.com/p/vogar/

Quick installation instructions (without rebuilding from source):
VOGAR=$HOME/vogar
svn co http://vogar.googlecode.com/svn/trunk/ $VOGAR
mkdir -p $VOGAR/build/
curl -o $VOGAR/build/vogar.jar https://vogar.googlecode.com/files/vogar.jar
PATH=$PATH:$VOGAR/bin

Within Google, you can find it under:
/home/dalvik-prebuild/vogar/bin/vogar

# You can also run openssl s_server as a test server on the device:
adb push ./android.testssl/CAss.cnf /sdcard/CAss.cnf
adb shell openssl req -config /sdcard/CAss.cnf -x509 -nodes -days 365 -subj '/C=US/ST=California/L=Mountain View/CN=localhost' -newkey rsa:1024 -keyout /sdcard/server.pem -out /sdcard/server.pem
adb shell openssl s_server -cert /sdcard/server.pem -www -verify 1
adb shell am start https://localhost:4433 # confirm result in browser

8) Do a full build before checking in:

m -j16

Optionally, check whether build flags (located in CONFIGURE_ARGS in
openssl.config, plus some extras in android-config.mk), need to be updated.
Doing this step will help ensure that the compiled library is appropriately
optimized for speed and size.

第六步很奇怪， mm -j 16后面为啥还adb remount && adb sync system 6) Build openssl from the external/openssl directory with: mm -j16 snod && adb remount && adb sync system

[袁保康]

adb remount && adb sync system 前者是将/system分区进行重新挂载，挂载成可以读写的，为后边向里边放文件作准备。 后者是同步新编译出的库文件到Android设备上。 总之一句话就类似你手动拷贝编译好的*.so到系统的/system/lib/目录下。

我也在搞这个，楼主一起讨论下怎么解决这个问题

[pengcao89]

完了还得adb reboot -->重启设备才可以吧。。 哈哈。 adb sync system 可能会提示你没法使用。。 会提示如下错误。 adb: Product directory not specified; use -p or define ANDROID_PRODUCT_OUT adb -p out/target/product/${YourProjectName}/ sync system 这样就好啦。。
