2019-09-23applypatch: Add backup_source parameter to PatchPartition.Tao Bao1-1/+1
And set it to false when installing recovery image via applypatch. We only need to back up the source partition when doing in-place update (e.g. when updating a given partition under recovery). When installing recovery image via applypatch, we won't touch the source partition (i.e. /boot). Removing the backup step also allows dropping the dac_override_allowed permission. Previously it was needed due to the access to /cache. Because applypatch runs as root:root, while /cache is owned by system:cache with 0770. Bug: 68319577 Test: Invoke the code that installs recovery image; check that recovery is installed successfully without denials. Test: recovery_unit_test passes on taimen.

2018-08-31applypatch: Refactor applypatch().Tao Bao1-33/+24
applypatch() was initially designed for file-based OTA, operating on individual files. It was later extended to allow patching eMMC targets as a whole, in favor of block-based updates. As we have deprecated file-based OTA since Oreo, part of the code in applypatch() has become obsolete. This CL refactors the related functions, by removing the obsolete logic and focusing on eMMC targets. Since this CL substantially changes applypatch APIs, it adds new functions to avoid unintentionally mixing them together. In particular, it removes `applypatch()`, `applypatch_check()`, `applypatch_flash()`, and adds `PatchPartition()`, `PatchPartitionCheck()`, `FlashPartition()` and `CheckPartition()`. It also replaces the old Edify functions `apply_patch()` and `apply_patch_check()` with `patch_partition()` and `patch_partition_check()` respectively. This CL requires matching changes to OTA generation script (in the same topic). Bug: 110106408 Test: Run recovery_unit_test and recovery_component_test on marlin. Test: `m dist` with non-A/B target. Verify /system/bin/install-recovery.sh on device. Test: `m dist` with non-A/B target using BOARD_USES_FULL_RECOVERY_IMAGE. Verify /system/bin/install-recovery.sh on device. Test: Install an incremental OTA with the new updater and scripts. Change-Id: Ia34a90114bb227f4216eb478c22dc98c8194cb7f
2018-07-20applypatch: Change applypatch command-line arguments.Tao Bao1-127/+134
This applies to the standalone applypatch executable (/system/bin/applypatch on device). This executable is only used when installing (via patching or flashing) a recovery image on non-A/B device. This CL removes the support for patching non-eMMC targets from applypatch that has been deprecated as part of file-based OTA. For patching eMMC targets, it also drops the support for accepting multiple patches (not useful, since the source file must be fixed). This CL needs the matching change in the same topic, which writes the script of "/system/bin/install-recovery.sh". Note that this CL doesn't chanage the applypatch API signatures, in order to minimize the CL size. *BEFORE* usage: /system/bin/applypatch [-b <bonus-file>] <src-file> <tgt-file> <tgt-sha1> <tgt-size> [<src-sha1>:<patch> ...] or /system/bin/applypatch -c <file> [<sha1> ...] or /system/bin/applypatch -l Filenames may be of the form EMMC:<partition>:<len_1>:<sha1_1>:<len_2>:<sha1_2>:... to specify reading from or writing to an EMMC partition. *AFTER* Usage: check mode applypatch --check EMMC:<target-file>:<target-size>:<target-sha1> flash mode applypatch --flash <source-file> --target EMMC:<target-file>:<target-size>:<target-sha1> patch mode applypatch [--bonus <bonus-file>] --patch <patch-file> --target EMMC:<target-file>:<target-size>:<target-sha1> --source EMMC:<source-file>:<source-size>:<source-sha1> show license applypatch --license Bug: 110106408 Test: Run recovery_component_test and recovery_unit_test on marlin.

2017-04-26applypatch: Remove the obsolete support for "applypatch -s".Tao Bao1-17/+1
The SpaceMode (applypatch -s) was used in amend script (cupcake) only, which has been removed since commit 9ce2ebf5d300eba5f6086583b0941ef68a3e4b42 (platform/build). The later (and current) edify script uses apply_patch_space(). Note that other modes (PatchMode, CheckMode) of applypatch executable are mostly used by install-recovery.sh script. Test: No active user of "applypatch -s". Test: recovery_component_test Change-Id: I1d689b7fedd3884077e88ed1d6c22f7a2198859d

Refactor applypatch/main.cpp into libapplypatch_modes so that we can add testcases.

2016-03-03Fix the improper use of LOCAL_WHOLE_STATIC_LIBRARIES.Tao Bao1-1/+1
If two libraries both use LOCAL_WHOLE_STATIC_LIBRARIES and include a same library, there would be linking errors when generating a shared library (or executable) that depends on the two libraries both. Also clean up Android.mk files. Remove the "LOCAL_MODULE_TAGS := eng" line for the updater module. The module will then default to "optional" which won't be built until needed.

2014-02-14remove 'retouch' ASLR supportDoug Zongker1-2/+2
Older versions of android supported an ASLR system where binaries were randomly twiddled at OTA install time. Remove support for this; we now use the ASLR support in the linux kernel. Change-Id: I8348eb0d6424692668dc1a00e2416fbef6c158a2
2012-08-21add bonus data feature to imgdiff/imgpatch/applypatchDoug Zongker1-2/+21
The bonus data option lets you give an additional blob of uncompressed data to be used when constructing a patch for chunk #1 of an image. The same blob must be available at patch time, and can be passed to the command-line applypatch tool (this feature is not accessible from edify scripts). This will be used to reduce the size of recovery-from-boot patches by storing parts of the recovery ramdisk (the UI images) on the system partition.

2010-02-23refactor applypatch and friendsDoug Zongker1-6/+141
Change the applypatch function to take meaningful arguments instead of argc and argv. Move all the parsing of arguments into main.c (for the standalone binary) and into install.c (for the updater function). applypatch() takes patches as Value objects, so we can pass in blobs extracted from the package without ever writing them to temp files. The patching code is changed to read the patch from memory instead of a file. A bunch of compiler warnings (mostly about signed vs unsigned types) are fixed. Support for the IMGDIFF1 format is dropped. (We've been generating IMGDIFF2 packages for some time now.) Change-Id: I217563c500012750f27110db821928a06211323f
2010-02-18relocate applypatch; add type system and new functions to edifyDoug Zongker1-0/+60
- Move applypatch to this package (from build). - Add a rudimentary type system to edify: instead of just returning a char*, functions now return a Value*, which is a struct that can carry different types of value (currently just STRING and BLOB). Convert all functions to this new scheme. - Change the one-argument form of package_extract_file to return a Value of the new BLOB type. - Add read_file() to load a local file and return a blob, and sha1_check() to test a blob (or string) against a set of possible sha1s. read_file() uses the file-loading code from applypatch so it can read MTD partitions as well. This is the start of better integration between applypatch and the rest of edify. b/2361316 - VZW Issue PP628: Continuous reset to Droid logo: framework-res.apk update failed (CR LIBtt59130) Change-Id: Ibd038074749a4d515de1f115c498c6c589ee91e5
