* Update Capstone to v4.0
* [Capstone-next] Update to capstone-next branch
* [Capstone-next] Update to Capstone-Next Branch
-[ARM]
-Add ARM_INS_MOVS support
-[ARM64]
-Remove vess.
-It overlaps with ARM64_VAS
-Fix A64SysReg_* into ARM64_SYSREG_*
-[PowerPC]
-Fix PPC_REG_X2 into PPC_REG_XER
-[X86]
-Remove X86_INS_FADDP
-In capstone-next, faddp is actually fadd, both belong to
"ID 15(fadd)"
* [tests][capstone2llvmir][arm] Fix MOVW Unit Test
- In test, "movw r0, #0xabcd" do not read any register
and the result is 0xabcd not 0x1234abcd
* [tests][capstone2llvmir][arm] Fix Nop test
- In arm, the NOP instruction is HINT instruction
- Also, in capstone, the cs_insn->id of nop is point to
HINT(ID: 63)
- So, an error will be occurred when looking for a translate
instruction method because it is points to nullptr

- when transalte "FXCH instruction, in the value of loadOpFloatingBinaryTop Function,
"top" is equal to idx, which causes the value to be written to top
twice when exchanging data.

The following variables were set in CMakeLists, however, they
were not used by the LLVM project build:
LLVM_USE_CRT_DEBUG
LLVM_USE_CRT_RELEASE

* Fixed loading import directory that is modified by relocations
* Fixed comment

There is absolutely no reason for it being in the code.

* Add a CHANGELOG entry for #1063
* Move signing certificate to separate object
* Updated authenticode parser to the newest version
* Fix uninitialize free, use finer sanity checks in auth. parser
* Add a directory for RetDec-related publications
The list of publications has been originally placed on
https://retdec.com/publications/ (https://retdec.com/ has been redirected
to https://github.com/avast/retdec, and we wanted to keep the list somewhere).
* Fix the wording for an invalid max-memory error in scripts/retdec-unpacker.py
There are the following two reasons for the fix:
- The check only verifies whether the passed value is an integer.
- The parameter can be 0 (i.e. a non-negative integer). It does not have to a
positive integer.
* Never try to limit memory on macOS
We can't limit memory on macOS. Before macOS 12
limitSystemMemoryOnPOSIX() does not actually do anything on macOS.
Anyway, it just succeed, since macOS 12 it returns error and retdec
can't start.
To be honest Apple can control memmory limit via so-called the ledger()
system call which is private. An old verison which was opened to
OpenSource (from 10.9-10.10?) using setrlimit() but at some point
setrlimit() was broken and not ledger(). Probably at macOS 12 the
setrlimit() was completley broken.
Because we haven't got any other choose just return true which haven't
change anything.
See: #379
Fixes: #1045
* Remove a redundant period from CHANGELOG
* utils: Improve the wording of a comment in getTotalSystemMemoryOnMacOS()
* Add a CHANGELOG entry for #1074 and #1045
* Update authenticode-parser, use-after-free, signedness issues
* Using multistage build for Dockerfile, reduces container size by ~1.5G
* Check for possible overflow when checking for segment overlaps. Fix incorrect range exception message
* Fix parameter and return types for dynamically called functions
Calls to dynamically-linked functions go through the procedure linkage
table (PLT). RetDec turns a PLT entry into a function, say
malloc@plt, that appears to do nothing but call the external function,
say malloc (though the assembly code will do a jump rather than a
call). User code that logically wants to call malloc instead calls
malloc@plt (and sets up arguments as if calling malloc). The
malloc@plt code first jumps to the dynamic linker which modifies it so
that subsequent calls to malloc@plt will jump directly to malloc. We
say that malloc@plt wraps malloc. The call to malloc in malloc@plt
will not have any arguments setup, so malloc will appear to have
no parameters or returns (unless that information is provided by
link-time-information, debug information, or name demangling), but it
needs to have the same parameter types and return type as
malloc@plt. The propagateWrapped methods copy the argument information
from the DataFlowEntry of the wrapping function to the wrapped
function. Then, when the calls to the wrapping function are inlined
(in connectWrappers), effectively the call to the wrapping function is
changed into a call to the wrapped function.
The motivation for this change is the programs that analyze the
output of RetDec (either the C code, or the LLVM code) want to
recognize library functions and treat them specially. This
change makes it so that the library function names are used
directly (rather than the plt version) and they are passed
their parameters correctly.
* Upgrade to Capstone release 4.0.2
* Add additional patch on capstone 4.0.2 for PPC Signed 16 bit immediates
Capstone version 4.0.2 has a bug when disassembling a powerpc instruction
with a signed 16-bit immediate.
See capstone-engine/capstone#1746 and
capstone-engine/capstone#1746 (comment).
This change adds to the capstone patch to fix this problem.
* Treat endbr32/endbr64 instructions as NOPs
* capstone2llvmir/powerpc: remove PPC_INS_BDZLA hack fix
As Capstone was updated, the fix in capstone-engine/capstone#968 took effect and the original RetDec fix is not needed - in fact, it caused problems.
* Handle Procedure Linkage calls for 32bit x86 from gcc
This case is for x86 32 bit compiled with GCC. Its PLT entries are in
sections .plt.sec or .plt.got. An entry is of the form:
jmp *offset(%ebx)
When this code is encountered register %ebx has been loaded with the
address of the start of the Global Offset Table (.got) section.
This change handles that case.
* Add ability to process PNG icons for perceptual hash calculation (#1090)
* Add ability to process PNG icons for perceptual hash calculation
* Use SCOPE_EXIT for deallocation
* In generated C, add prototypes for dynamically-linked functions without headers
When the program involves dynamically-linked functions like _Znwj
(operator new) that return a pointer, it is necessary to have
prototypes for them, since otherwise they will be implicitly deduced
to return "int" which cannnot be dereferenced.
Previously RetDec was emitting comments telling which functions were
dynamically linked. This change moves them up before the functions are
emitted and instead emits prototypes for the functions. However,
RetDec also inserts includes of headers for functions for with know
headers. We do not emit prototypes for functions with headers as that
would be redundant. As a result, some dynamically-linked functions
that used to show in the comments no longer appear as the included
header will declare them.
The section header comment for dynamically-linked functions is only
produced if some prototypes are written for dynamically-linked
functions.
A related PR will have added tests as well as changes needed for
existing tests.
* Add printing of analysis time to retdec-fileinfo output
* Yara: inherits linker flags
* Use provided libtool via `CMAKE_LIBTOOL`
* Added missed `${RETDEC_INSTALL_BIN_DIR}` to `pat2yara`
* Added sanity check for page index when loading pages from broken samples
There are certain samples where page index might go beyond available
pages when trying to load them which will be prevented with this patch.
* Virtual Size overflow is now handler properly
* Fixed error code
* Updated yaramod
* Fix removeZeroSequences
* README.md: add "limited maintenance mode" note
