/** * Fuzz target interface. * Fuzz targets have some common parameters passed as macros during compilation. * Check the documentation for each individual fuzzer for more parameters. * * @param FUZZ_RNG_SEED_SIZE: * The number of bytes of the source to look at when constructing a seed * for the deterministic RNG. These bytes are discarded before passing * the data to lz4 functions. Every fuzzer initializes the RNG exactly * once before doing anything else, even if it is unused. * Default: 4. * @param LZ4_DEBUG: * This is a parameter for the lz4 library. Defining `LZ4_DEBUG=1` * enables assert() statements in the lz4 library. Higher levels enable * logging, so aren't recommended. Defining `LZ4_DEBUG=1` is * recommended. * @param LZ4_FORCE_MEMORY_ACCESS: * This flag controls how the zstd library accesses unaligned memory. * It can be undefined, or 0 through 2. If it is undefined, it selects * the method to use based on the compiler. If testing with UBSAN set * MEM_FORCE_MEMORY_ACCESS=0 to use the standard compliant method. * @param FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION * This is the canonical flag to enable deterministic builds for fuzzing. * Changes to zstd for fuzzing are gated behind this define. * It is recommended to define this when building zstd for fuzzing. */ #ifndef FUZZ_H #define FUZZ_H #ifndef FUZZ_RNG_SEED_SIZE # define FUZZ_RNG_SEED_SIZE 4 #endif #include #include #ifdef __cplusplus extern "C" { #endif int LLVMFuzzerTestOneInput(const uint8_t *src, size_t size); #ifdef __cplusplus } #endif #endif
