0.4.0

Added

  • Update README to include new command line options for all BARF tools.
  • Add initial support for x86 AVX instruction set.
  • Add support for x86 instructions: BSF, BSWAP, BTS, CDQ, MOVSXD and SHRD.
  • Add support for x86 SSE instructions: MOVD, MOVDQA, MOVDQU, MOVHPD, MOVLPD, MOVQ, PCMPEQB, PMINUB, PMOVMSKB, POR, PSHUFD, PSLLDQ, PSRLDQ, PSUBB, PUNPCKLBW, PUNPCKLWD, PUNPCKLQDQ and PXOR.
  • Add initial support for x86 SSE instruction set.
  • Add support for pdf, png and dot output formats in BARFcfg and BARFcg tools.
  • Add option to display immediate operand values in hex and dec to the CFG rendering.
  • Add REIL instruction index to the CFG rendering.
  • Add support for missing x86 flag translations: AF and PF.
  • Add new method to the ArchitectureInformation class to retrieve information about syscall instructions.
  • Add new x86 example for finding and executing functions.
  • Add new methods to the CallGraph class.
  • Add initial support for GS and FS segments access (x86).

Changed

  • Improve coding style and code quality of the reil module.
  • Improve coding style and code quality of the reilemulator module.
  • Remove SMT requirement (an exception is raised when trying to use related functionality).
  • Improve coding style and code quality of the x86 package.
  • Improve emulate_full method to support any piece of code.
  • Refactor _open_elf logic in the BinaryFile class by @Seraphime.

Fixed

  • Fix missing check on recover_cfg function parameters.
  • Update missing branch instructions in the X86ArchitectureInformation class.
  • Fix x86 instruction translation: SAR, SHR, SHL, ROR, MOVZX and MOV.
  • Fix x86 gadget finding function.

  • Fix x86 REP prefix parsing.

0.3 - 2016-12-13

Added

  • Add new BARF tool, BARFcg, for CG recovery.
  • Add support for CG recovery (x86 and ARM).
  • Add new BARF tool, BARFcfg, for CFG recovery.
  • Add support for ARM CFG recovery.
  • Add support for more ARM instructions.
  • Add support for data tainting in ReilEmulator.
  • Add support for pre/post instruction execution callback function in ReilEmulator.
  • Add support for REIL extension instruction (SEXT, SDIV, SMOD).
  • Add support for more x86 instructions.

Changed

  • Improve CFG recovery functionality.
  • Refactor basickblock module.
  • Replace PyBFD with PyELFTools.
  • Improve SMT performace.
  • Refactor smtlibv2 module.
  • Overall directory restructure.
  • Improve ARM disassembly integration to Capstone Engine.
  • Overall improvements to CFG recovery and rendering.
  • Refactor reilemulator module.
  • Overall improvements to package's tests.

Fixed

  • Multiple bug fixes.

Removed

  • Remove PyAsmJIT package from the repository (move to its own repo).

0.2.1 - 2015-04-07

Fixed

  • Fix Python logging module setup issue.

0.2 - 2015-04-06

Added

  • BARFgadgets now find gadgets in ARM binaries.
  • Add support for the ARM architecture (32 btis).
  • Add support for more x86 instructions.
  • Memory consumption reduction through the use of __slots__.
  • BARFgadgets now supports gadgets ending in RET imm16, JMP and CALL instructions.

Changed

  • Overall improvements to x86 package (major changes that ended up in performance increase of translation up to 3x!).
  • Overall improvements to reil package (minor changes).
  • New reil translation scheme for x86 instructions.
  • x86translator and x86instructiontranslator modules were merged.
  • Some methods of X86ArchitectureInformation class were renamed to improve naming consistency.
  • x86 flags are now represented using a single bit (instead of one byte). Also, each flag (CF, ZF, etc.) is now an alias of the correspondent bit of the {e/r}flags register.

Fixed

  • Fixes in x86 instruction translations (mostly flags update issues.)
  • Fix missing registers in X86ArchitectureInformation class.
  • Fix SMT translation for STR instruction when dst operand is bigger than src operand.

Removed

  • x86instruction and x86intructiontranslator modules were removed.

0.1 - 2014-11-19

Added

  • First release.
