Environment variables in compiling

  • USE_FAST=1: use fast mode to compile the program. It includes branch counting, getting the feedback of the fuzzing constraint (the output of its function).
  • USE_TRACK=1: use taint tracking and collect all constraints.
  • USE_DFSAN=1: use taint tracking.
  • ANGORA_DISABLE_CONTEXT=1 : Disable function call based contexts in compiling.
  • ANGORA_GEN_ID_RANDOM=1 : Generate ids for predicates randomly instead of the hash of their locations.
  • ANGORA_OUTPUT_COND_LOC=1 : (Debug option) Output the location of each predicate during compiling.
  • ANGORA_TAINT_CUSTOM_RULE=/path/to/object : object contains those proxy function (how to propagate taints), e.g. ANGORA_TAINT_CUSTOM_RULE=~/angora/bin/zlib-func.o . You should add it as custom type in the file passed by ANGORA_TAINT_RULE_LIST first.
  • ANGORA_TAINT_RULE_LIST=/path/to/list : DataFlowSanitizer’s ABI list, e.g. ANGORA_TAINT_RULE_LIST=~/angora/bin/extra_list.txt.
