* More cleanup to imgdiff & imgpatchTianjie Xu2017-03-161-9/+6
| | | | | | | | Also remove the utils in applypatch and replace them with the corresponding libbase functions. Test: recovery tests pass. Change-Id: I77254c141bd3e7d3d6894c23b60e866009516f81
* Refractor the code for imgdiffTianjie Xu2017-03-071-0/+3
| | | | | | | | | | | Put ImageChunk and some helper functions into a class. Also switch to using std::vector instead of malloc. Bug: 18606652 Test: imgdiff_test passed on host. Also generate a complete incremental OTA package. The file content is the same and time consumption is similar. Change-Id: Id603ada4e130ef521218400761a119001a86ca79
* Use bspatch from external/bsdiff.Sen Jiang2017-02-021-0/+4
| | | | | | | | | | Now ApplyBSDiffPatch() will stream the output to sink as we go instead of sinking everything at the end. Test: recovery_host_test Bug: 26982501 Change-Id: I05b6ed40d45e4b1b19ae72784cf705b731b976e3

| * imgpatch: Compile with ZLIB_CONST defined.Tao Bao2017-01-201-3/+9
| | | | | | | | | | | | | | So z_stream.next_in takes pointer to const data. Test: mmma bootable/recovery/applypatch Change-Id: If269b766a7c84fa2f67424ee61ba5afab0159261
* | imgdiff: cache bsdiff suffix array in zip mode.Sen Jiang2017-01-191-3/+3
|/ | | | | | | | | | | In zip mode, if a chunk is not deflate or its filename can't be found in source chunks, the entire source file is used as old data for bsdiff, To avoid repeatedly construct the suffix array used by bsdiff, we cache the suffix array of the entire source file. Bug: 34281147 Test: =time -v imgdiff -z Chrome-ORF74B.apk Chrome-ORF76B.apk Chrome.imgdiff Change-Id: Ifd957ccecf7226fcb44dbf28c58969a06ef74f4b
* imgdiff: Fix an edge case that leads to infinite loop.Tao Bao2016-12-281-0/+1
| | | | | | | | | When the input image ends with the magic value sequence of 0x1f, 0x8b, 0x0b (optionally with 0x00), the image parsing code will be stuck in an infinite loop. Test: recovery_component_test passes. Change-Id: Ie3629dfdc41360387b19cc3e0359c95ae4fb998e
* Add tests for imgdiff.Tao Bao2016-12-201-21/+69
| | | | | | | | | | | | Factor out libimgdiff static library for testing purpose. This CL adds the imgdiff tests on host and on target both (similar to libimgpatch). In practice, we only need imgdiff binary on host, and libimgpatch on target. But they should build and pass tests on both platforms. Test: recovery_host_test passes; recovery_component_test passes. Change-Id: I0eafb7faf727cdf70066310e845af6ee245d4f60
* applypatch: Add testcases for applypatch executable.Tao Bao2016-11-011-5/+25
| | | | | | | | | | | | | | | Refactor applypatch/main.cpp into libapplypatch_modes so that we can add testcases. Some changes to applypatch/main.cpp: - Replace char** argv with const char**; - Use android::base::Split() to split ":"; - Use android::base::ParseUInt(). Bug: 32383590 Test: Unit tests pass, install-recovery.sh works. Change-Id: I44e7bfa5ab717d439ea1d0ee9ddb7b2c40bb95a4
* Replace minzip with libziparchiveTianjie Xu2016-10-181-1/+0
| | | | | | | | | | | Clean up the duplicated codes that handle the zip files in bootable/recovery; and rename the library of the remaining utility functions to libotautil. Test: Update package installed successfully on angler. Bug: 19472796 Change-Id: Iea8962fcf3004473cb0322b6bb3a9ea3ca7f679e
* Turn on -Werror for recoveryTianjie Xu2016-09-301-0/+5
| | | | | | | | | | Also remove the 0xff comparison when validating the bootloader message fields. As the fields won't be erased to 0xff after we remove the MTD support. Bug: 28202046 Test: The recovery folder compiles for aosp_x86-eng Change-Id: Ibb30ea1b2b28676fb08c7e92a1e5f7b6ef3247ab
* Switch recovery to libbase loggingTianjie Xu2016-09-011-1/+1

* applypatch: Use bsdiff from external/bsdiff.Sen Jiang2016-05-041-2/+7
| | | | | | | | | | external/bsdiff uses divsufsort which is much faster, and also include some bug fixes. Bug: 26982501 Test: ./imgdiff_test.sh Change-Id: I089a301c291ee55d79938c7a3ca6d509895440d1
* Fix the improper use of LOCAL_WHOLE_STATIC_LIBRARIES.Tao Bao2016-03-031-20/+44
| | | | | | | | | | | | | 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.

| | | | | | Disable libimgpatch for non-Linux host. Change-Id: Ib3615204b76564c691ddafaa29e59fef334d9d36
* applypatch: Compile libimgpatch for target and host.Sen Jiang2016-01-281-1/+23
| | | | | | | | | | | | | update_engine need it for the new IMGDIFF operation. Also removed __unused in ApplyImagePatch() as I got error building it for the host, and I think it's dangerous not checking the size of the input. Test: mma Bug: 26628339 Change-Id: I22d4cd55c2c3f87697d6afdf10e8106fef7d1a9c
* Remove the building rules for applypatch_static.Tao Bao2015-12-021-13/+0
| | | | | | | | | | The CL in [1] has stopped building and packaging the obsolete applypatch_static tool. [1]: commit a04fca31bf1fadcdf982090c942ccbe4d9b95c71 Bug: 24621915 Change-Id: I5e98951ad7ea5c2a7b351af732fd6722763f59bd

* Stop using libstdc++.Dan Albert2015-05-191-2/+2
| | | | | | | | These are already getting libc++, so it isn't necessary. If any of the other static libraries (such as adb) use new or delete from libc++, there will be symbol collisions. Change-Id: I55e43ec60006d3c2403122fa1174bde06f18e09f

* Working ASLR implementationHristo Bojinov2010-08-021-2/+2
| | | | | | | | | | Separate files for retouch functionality are in minelf/* ASLR for shared libraries is controlled by "-a" in ota_from_target_files. Binary files are self-contained. Retouch logic can recover from crashes. Signed-off-by: Hristo Bojinov <hristo@google.com> Change-Id: I76c596abf4febd68c14f9d807ac62e8751e0b1bd

* refactor applypatch and friendsDoug Zongker2010-02-231-0/+2
| | | | | | | | | | | | | | | | | | | 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
* relocate applypatch; add type system and new functions to edifyDoug Zongker2010-02-181-0/+59
- 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
