* imgdiff: Fix an edge case that leads to infinite loop.Tao Bao2016-12-281-15/+10
| | | | | | | | | 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 Bao2016-12-201-30/+24
| | | | | | | | | | | | 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.

* | Use static_cast to cast pointers returned by malloc/calloc/realloc/mmap.Rahul Chaudhry2016-11-161-16/+16
|/ | | | | | | | | | | static_cast is preferable to reinterpret_cast when casting from void* pointers returned by malloc/calloc/realloc/mmap calls. Discovered while looking at compiler warnings (b/26936282).

* Revert "Fix memory/resource handling in imgdiff.cpp, using unique_ptr and vector."Tao Bao2016-06-011-38/+40
| | | | | | This reverts commit 50a6f8c8335be920833d06e5dabd37de279c98a9. A mix of new and free leads to memory corruptions.

* applypatch: Use bsdiff from external/bsdiff.Sen Jiang2016-05-041-14/+3
| | | | | | | | | | external/bsdiff uses divsufsort which is much faster, and also include some bug fixes. Bug: 26982501 Test: ./imgdiff_test.sh Change-Id: I089a301c291ee55d79938c7a3ca6d509895440d1

| | | | | | | | Treat it as a normal chunk if inflate() fails. Test: run imgdiff on corrupted gzip and apply the patch Bug: 27153028 Change-Id: Idcbb3c1360ec0774e6c7861b21d99af8ee10604a
* applypatch: Add a Makefile to build imgdiff in Chrome OS.Sen Jiang2016-02-101-2/+0
| | | | | | | | | Also fixed some warnings and added check for target_len. Test: mma; emerge-peppy imgdiff; emerge-nyan imgdiff; sudo emerge imgdiff Bug: 26866274 Change-Id: Ifbcd3afd6701c769ccf626e33ed94461706f7ee6
* imgdiff: skip spurious gzip headers in image filesDavid Riley2015-12-231-6/+13
| | | | | | | | | | | | | dragon kernel is compressed via lz4 for boot speed and bootloader support reasons and recent prebuilts happen to include the gzip header sequence which is causing imgdiff to fail. Detect a spurious gzip header and treat the section as a normal section.

| | | | | | | | | | mkstemp() allocates a file description that is never released. If MakePatch() is called too many time, imgdiff reaches the Operating System EMFILE (too many open files) limit.
