Regression(?) in Module.enumerateExports and Module.enumerateSymbols

[leonitousconforti]

Every since upgrading Frida server to >= 16.1.0, Module.enumerateExports and Module.enumerateSymbols both yield empty lists and provide no results, despite that I can print a list of symbols using objdump or nm. If I revert back to Frida server 16.0.19, I can print all the symbols and exports of the binary correctly. I tested all versions of Frida sever >= 16.0.19 with all versions of frida-node >= 16.0.19 and my conclusions are that it doesn't matter what version of frida-node I use, but any frida-server >= 16.0.19 doesn't work (i.e it can't find the exports/symbols anymore).

Here is some information about the binary:

libil2cpp.so: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, BuildID[sha1]=e0c975c6950ff035f0f696337eaa3760e986c7f6, stripped

If I use nm or objdump on the binary, it can find all the symbols I am interested in:

nm -D libil2cpp.so | grep il2cpp_

and I can indeed access the symbols at those offsets inside Frida.

I can see a lot has changed between 16.0.19 and 16.1.0. I think I am going to start with the changes in frida-gum, if you have any idea or insights about where I should start looking though that would be extremely helpful.
