[BUG] ERROR /usr/local/lib/python3.11/dist-packages/pyarmor/cli/core/pytransform3.so: invalid ELF header #969

SamComber · 2023-03-13T10:00:30Z

I've installed pyarmor 8.0.1 inside a container, I haven't yet supplied a license (we have a license for 5.6.0 pyarmor and not sure if this will work with pyarmor 8.0.1).

I'm running a very simple obfuscation to do a quick test with the new version inside my hardware, and in accordance to trial version rules The maximum size of code object is 35728 bytes in trial version

What is going on here?

jondy · 2023-03-15T05:58:45Z

Pyarmor 8.0.x only works x86_64 platforms, other platforms will be supported later.

SamComber · 2023-03-15T07:50:34Z

@jondy, but I’m running this inside container with virtual “x86_64”, will this only work on actual x86_64 and not in container ?

jondy · 2023-03-16T01:22:39Z

This is Alpine, it use musl-c, not glib-c.

It will be supported later.

fO-000 · 2023-03-16T10:11:13Z

@jondy I also encountered this issue on the following system, is it caused by musl-c too?

This python script could check which c lib is used, now only glib-c is supported:

import platform
print(platform.libc_ver())

fO-000 · 2023-03-16T13:10:29Z

Confirmed, my system is using glib-c 2.36, but also encountered this issue:

Python 3.11.2 (main, Feb 12 2023, 00:48:52) [GCC 12.2.0] on linux

>>> 
>>> import platform
>>> print(platform.libc_ver())

SamComber · 2023-03-16T13:42:17Z

My system also...

jondy · 2023-03-16T15:27:12Z

@fO-000 @SamComber
If arch and libc are ok, another possible cause: endianness mismatch
now only little is supported

SamComber · 2023-03-16T15:29:24Z

Seems the system is little endian, what else could be causing this?

jondy · 2023-03-16T15:57:34Z

Check it by ldd

ldd /path/to/pyarmor/cli/core/pytransform3.so

SamComber · 2023-03-16T16:02:19Z

@jondy , my guess is the below would work on little endian system? Thanks for your work on pyarmor 8+ release btw :)

root@aa456d15085d:/# ldd /usr/local/lib/python3.11/dist-packages/pyarmor/cli/core/pytransform3.so
	not a dynamic executable

fO-000 · 2023-03-17T03:46:58Z

@jondy Would you reopen this issue?

@SamComber My output is exactly the same as yours.

But another way of checking pytransform3.so dependencies outputs the following:

$ env LD_TRACE_LOADED_OBJECTS=1 /home/x/.local/lib/python3.11/site-packages/pyarmor/cli/core/pytransform3.so
	linux-vdso.so.1 (0x00007ffe8c132000)
	libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f5346e3e000)
	/lib64/ld-linux-x86-64.so.2 (0x00007f534704a000)

fO-000 · 2023-03-17T08:03:21Z

@jondy Found that the pytransform3.so file is in Mac format instead of Linux format:

$ file ~/.local/lib/python3.11/site-packages/pyarmor/cli/core/pytransform3.so
/home/x/.local/lib/python3.11/site-packages/pyarmor/cli/core/pytransform3.so: Mach-O 64-bit x86_64 dynamically linked shared library, flags:<NOUNDEFS|DYLDLINK|TWOLEVEL|NO_REEXPORTED_DYLIBS>

jondy · 2023-03-17T08:51:12Z

@fO-000 Thanks.

I'll check it.

jondy · 2023-03-17T08:57:06Z

@fO-000 please upgrade pyarmor.cli.core to 1.0.1, I just check this wheel

$ unzip pyarmor.cli.core-1.0.1-cp311-none-manylinux1_x86_64.whl
$ file pyarmor/cli/core/pyarmor_runtime.so 
pyarmor/cli/core/pyarmor_runtime.so: ELF 64-bit LSB pie executable x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=f2a3921afb9eb55d2ff615840e8e400926d8f103, stripped

fO-000 · 2023-03-17T09:33:07Z

Great, the issue is solved with pyarmor.cli.core version 1.0.1. But a new error appeared, like #983.
