CMakeLists.txt: Add missing add_dependencies
2023-10-26CMakeLists.txt: Add missing add_dependenciesHarish Mahendrakar
add_dependencies() calls are needed to ensure that cmake builds work as expected when running multiple compile jobs in parallel.
2023-10-25Apply current project compilation flags to external projectsRam Mohan
cflags, cxxflags, sanitize flags as of now are applied only to current project. Extend these to its dependencies as well ensure clean target, cleans dependencies as well

Cleanup CMakeLists.txt and Update README.md
2023-10-24rework jpeg encoder and decoder helper utilsRam Mohan
If luma stride is aligned and chroma stride is not aligned to mcu row, jpeg_write_raw_data() is using unaligned chroma pointers during processing. This should cause oob reads. This is fixed. Allocate memory for alignment regions only when necessary. After decompress, dont copy decoded rows that are outside image boundaries.

Allocate width aligned to MCU size for boundary rows
2023-10-21Allocate width aligned to MCU size for boundary rowsRam Mohan
jpeg_write_raw_data() expects input size to be aligned to MCU. If the image dimensions are not aligned then padding is done for boundary rows. The padded rows allocation is not proper and this is corrected. Bug: oss-fuzz-63314 Test: ultrahdr_enc_fuzzer

2023-10-18Memory leaks due to longjmp over std::unique_ptr dtorsRam Mohan
The jpeg decoder helper class is using long jumps if errors are seen during decode. This is by passing the calls to destructors of std::unique_ptr causing a memory leak. Move these allocs to parent class there by ensuring the dtor calls Bug: oss-fuzz-63337 Test: ./ultrahdr_dec_fuzzer
2023-10-18Address memory leak in ultrahdr unit testsRam Mohan
GenerateGainMap allocates memory to store gain map data. It is the caller's responsibility to release the memory after usage. The unit test is not currently releasing this memory causing a leak Test: ./ultrahdr_unit_test

Use ALOG methods to print messages from jpeg and image_io
2023-10-03Use ALOG methods to print messages from jpeg and image_ioHarish Mahendrakar
- Override output_message method for jpeg decoder - Use SetMessageWriter() while calling Jpeg scanner from image_io This ensures that logs are written using ALOG routines and can be suppressed for fuzzer runs easily.
2023-10-03cmake updatesHarish Mahendrakar
- Build only jpeg-static - Add variables for libjpeg-turbo and gtest includes and libraries - add dependencies on libjpeg-turbo and gtest to ensure they are built first before building the app, unit test and fuzzers
