Android 7.0修改PMS逻辑添加权限白名单

今天有任务安排需要实现给任何一个应用在不动态申请权限的情况下，实现权限赋予，大体知道应用权限的赋予逻辑是在PMS中，于是大概研究了下，最终的手段就是在install安装时，就把应用程序AndroidManifest中请求的权限赋予它，但是时间有限，跟踪了下应用安装的逻辑，往上走还是非常复杂，就暂且放下了。

解决方案：

在PMS的grantPermissionsLPw方法中的if ((changedInstallPermission || replace) && !ps.installPermissionsFixed && !isSystemApp(ps) || isUpdatedSystemApp(ps)){ 判断条件之前加上如下代码，其中的whiteList是自己定义的一个白名单数组，保存着目标应用的包名。

        if (Arrays.asList(whiteList).contains(pkg.packageName)) {final int permsSize = pkg.requestedPermissions.size();for (int i = 0; i < permsSize; i++) {final String name = pkg.requestedPermissions.get(i);final BasePermission bp = mSettings.mPermissions.get(name);if (null != bp && permissionsState.grantInstallPermission(bp) != PermissionsState.PERMISSION_OPERATION_FAILURE) {Slog.d(TAG, "grant permission " + name + " to package " + pkg.packageName);changedInstallPermission = true;}}}

添加后的截图如下：

添加的代码的意思也非常清楚，就是对当前应用需要申请的权限全部赋为true，这样应用就可以不动态申请，就直接有了想要的权限了；手机上所有应用的部分信息都保存在/data/system/packages.xml文件中，应用申请的权限在当前应用包名的xml根节点下明确记录，实例截图如下。

本来想把install应用安装的逻辑完全搞清楚，但是进来后发现这块还真是复杂，加上时间不够，有要事在身，就把install安装的系统日志贴出来吧，供大家参考。

我是在cmd中adb install命令行执行安装的，发现的入口点是在PackageInstallerSession.java类的commitLocked方法中调用PMS类的installStage方法来进行安装的。PackageInstallerSession.java类的commitLocked方法源码如下：

    private void commitLocked(PackageInfo pkgInfo, ApplicationInfo appInfo)throws PackageManagerException {if (mDestroyed) {throw new PackageManagerException(INSTALL_FAILED_INTERNAL_ERROR, "Session destroyed");}if (!mSealed) {throw new PackageManagerException(INSTALL_FAILED_INTERNAL_ERROR, "Session not sealed");}try {resolveStageDir();} catch (IOException e) {throw new PackageManagerException(INSTALL_FAILED_CONTAINER_ERROR,"Failed to resolve stage location", e);}// Verify that stage looks sane with respect to existing application.// This currently only ensures packageName, versionCode, and certificate// consistency.validateInstallLocked(pkgInfo, appInfo);Preconditions.checkNotNull(mPackageName);Preconditions.checkNotNull(mSignatures);Preconditions.checkNotNull(mResolvedBaseFile);if (!mPermissionsAccepted) {// User needs to accept permissions; give installer an intent they// can use to involve user.final Intent intent = new Intent(PackageInstaller.ACTION_CONFIRM_PERMISSIONS);intent.setPackage(mContext.getPackageManager().getPermissionControllerPackageName());intent.putExtra(PackageInstaller.EXTRA_SESSION_ID, sessionId);try {mRemoteObserver.onUserActionRequired(intent);} catch (RemoteException ignored) {}// Commit was keeping session marked as active until now; release// that extra refcount so session appears idle.close();return;}if (stageCid != null) {// Figure out the final installed size and resize the container once// and for all. Internally the parser handles straddling between two// locations when inheriting.final long finalSize = calculateInstalledSize();resizeContainer(stageCid, finalSize);}// Inherit any packages and native libraries from existing install that// haven't been overridden.if (params.mode == SessionParams.MODE_INHERIT_EXISTING) {try {final List<File> fromFiles = mResolvedInheritedFiles;final File toDir = resolveStageDir();if (LOGD) Slog.d(TAG, "Inherited files: " + mResolvedInheritedFiles);if (!mResolvedInheritedFiles.isEmpty() && mInheritedFilesBase == null) {throw new IllegalStateException("mInheritedFilesBase == null");}if (isLinkPossible(fromFiles, toDir)) {if (!mResolvedInstructionSets.isEmpty()) {final File oatDir = new File(toDir, "oat");createOatDirs(mResolvedInstructionSets, oatDir);}linkFiles(fromFiles, toDir, mInheritedFilesBase);} else {// TODO: this should delegate to DCS so the system process// avoids holding open FDs into containers.copyFiles(fromFiles, toDir);}} catch (IOException e) {throw new PackageManagerException(INSTALL_FAILED_INSUFFICIENT_STORAGE,"Failed to inherit existing install", e);}}// TODO: surface more granular state from dexoptmInternalProgress = 0.5f;computeProgressLocked(true);// Unpack native librariesextractNativeLibraries(mResolvedStageDir, params.abiOverride);// Container is ready to go, let's seal it up!if (stageCid != null) {finalizeAndFixContainer(stageCid);}// We've reached point of no return; call into PMS to install the stage.// Regardless of success or failure we always destroy session.final IPackageInstallObserver2 localObserver = new IPackageInstallObserver2.Stub() {@Overridepublic void onUserActionRequired(Intent intent) {throw new IllegalStateException();}@Overridepublic void onPackageInstalled(String basePackageName, int returnCode, String msg,Bundle extras) {destroyInternal();dispatchSessionFinished(returnCode, msg, extras);}};final UserHandle user;if ((params.installFlags & PackageManager.INSTALL_ALL_USERS) != 0) {user = UserHandle.ALL;} else {user = new UserHandle(userId);}mRelinquished = true;mPm.installStage(mPackageName, stageDir, stageCid, localObserver, params,installerPackageName, installerUid, user, mCertificates);}

这里的mPm就是PackageManagerService了，执行到installStage方法中，会先通过PMS中mHandler成员变量发送一条INIT_COPY消息，mHandler是PMS的内部类PackageHandler，它在handleMessage方法中就是直接调用doHandleMessage方法去处理安装逻辑的，doHandleMessage方法源码如下：

void doHandleMessage(Message msg) {switch (msg.what) {case INIT_COPY: {HandlerParams params = (HandlerParams) msg.obj;int idx = mPendingInstalls.size();if (DEBUG_INSTALL) Slog.i(TAG, "init_copy idx=" + idx + ": " + params);// If a bind was already initiated we dont really// need to do anything. The pending install// will be processed later on.if (!mBound) {Trace.asyncTraceBegin(TRACE_TAG_PACKAGE_MANAGER, "bindingMCS",System.identityHashCode(mHandler));// If this is the only one pending we might// have to bind to the service again.if (!connectToService()) {Slog.e(TAG, "Failed to bind to media container service");params.serviceError();Trace.asyncTraceEnd(TRACE_TAG_PACKAGE_MANAGER, "bindingMCS",System.identityHashCode(mHandler));if (params.traceMethod != null) {Trace.asyncTraceEnd(TRACE_TAG_PACKAGE_MANAGER, params.traceMethod,params.traceCookie);}return;} else {// Once we bind to the service, the first// pending request will be processed.mPendingInstalls.add(idx, params);}} else {mPendingInstalls.add(idx, params);// Already bound to the service. Just make// sure we trigger off processing the first request.if (idx == 0) {mHandler.sendEmptyMessage(MCS_BOUND);}}break;}case MCS_BOUND: {if (DEBUG_INSTALL) Slog.i(TAG, "mcs_bound");if (msg.obj != null) {mContainerService = (IMediaContainerService) msg.obj;Trace.asyncTraceEnd(TRACE_TAG_PACKAGE_MANAGER, "bindingMCS",System.identityHashCode(mHandler));}if (mContainerService == null) {if (!mBound) {// Something seriously wrong since we are not bound and we are not// waiting for connection.

在INIT_COPY中，成员变量mBound是在connectToService方法执行成功已经赋值为true了，所有会执行else分支，继续发一条MCS_BOUND消息，MCS_BOUND消息中会执行else if (mPendingInstalls.size() > 0)分支，在这里的if (params.startCopy())就会调用给应用赋予权限的逻辑了，params的类型为HandlerParams，它的startCopy()拷贝完成后，最后调用handleReturnCode继续处理，handleReturnCode是由子类InstallParams来实现的，它当中直接调用processPendingInstall往mHandler所在的线程上发了一条Runnable消息，Runnable中继续调用installPackageTracedLI处理，installPackageTracedLI方法又继续调用installPackageLI方法处理，installPackageLI方法在执行到15451行的try (PackageFreezer freezer = freezePackageForInstall(pkgName, installFlags, "installPackageLI"))逻辑时，因为是新安装，此处理的replace为false，执行installNewPackageLIF方法继续处理，方法注释上也写的很清楚了，是安装新应用时执行的，installNewPackageLIF方法的源码如下：

    /** Install a non-existing package.*/private void installNewPackageLIF(PackageParser.Package pkg, final int policyFlags,int scanFlags, UserHandle user, String installerPackageName, String volumeUuid,PackageInstalledInfo res) {Trace.traceBegin(TRACE_TAG_PACKAGE_MANAGER, "installNewPackage");// Remember this for later, in case we need to rollback this installString pkgName = pkg.packageName;if (DEBUG_INSTALL) Slog.d(TAG, "installNewPackageLI: " + pkg);synchronized(mPackages) {if (mSettings.mRenamedPackages.containsKey(pkgName)) {// A package with the same name is already installed, though// it has been renamed to an older name.  The package we// are trying to install should be installed as an update to// the existing one, but that has not been requested, so bail.res.setError(INSTALL_FAILED_ALREADY_EXISTS, "Attempt to re-install " + pkgName+ " without first uninstalling package running as "+ mSettings.mRenamedPackages.get(pkgName));return;}if (mPackages.containsKey(pkgName)) {// Don't allow installation over an existing package with the same name.res.setError(INSTALL_FAILED_ALREADY_EXISTS, "Attempt to re-install " + pkgName+ " without first uninstalling.");return;}}try {PackageParser.Package newPackage = scanPackageTracedLI(pkg, policyFlags, scanFlags,System.currentTimeMillis(), user);updateSettingsLI(newPackage, installerPackageName, null, res, user);if (res.returnCode == PackageManager.INSTALL_SUCCEEDED) {prepareAppDataAfterInstallLIF(newPackage);} else {// Remove package from internal structures, but keep around any// data that might have already existeddeletePackageLIF(pkgName, UserHandle.ALL, false, null,PackageManager.DELETE_KEEP_DATA, res.removedInfo, true, null);}} catch (PackageManagerException e) {res.setError("Package couldn't be installed in " + pkg.codePath, e);}Trace.traceEnd(TRACE_TAG_PACKAGE_MANAGER);}

在这里的try模块中执行updateSettingsLI更新Settings，又调用updateSettingsInternalLI处理，接着调用updatePermissionsLPw更新应用权限，updatePermissionsLPw方法中就是直接调用updatePermissionsLPw方法处理，该方法中最后就会执行grantPermissionsLPw给应用写权限，而我们加在这里的逻辑也就生效了。

从这里看，这还只是写权限的部分逻辑，应用安装还涉及到其他很多问题，真是非常复杂，大家有研究清楚的，也请多多指教，最后把我在系统中加的日志贴出来，供大家参考。
