Abstract

An information handling system, method, and computer-readable media for obfuscating debugging filenames during a software build are described. The system comprises one or more processors, a memory, and one or more program modules stored on the memory and executable by the one or more processors. The one or more program modules compile a source code file of a plurality of source code files into a program, generate a debugging file including debugging information for the program, utilize a one-way deterministic function to generate an obfuscated filename for the debugging file, and include a link to the debugging file in the program, the link including the obfuscated filename.

First claim

What is claimed is:

1. An information handling system for obfuscating debugging filenames during a software build, the information handling system comprising:
one or more processors;
a memory;
one or more program modules stored on the memory and executable by the one or more processors to:
compile a source code file or a plurality of source code files into software modules;
pass file names of the software modules to a script;
generate, at least in part by the script and based at least in part on a one-way deterministic function, obfuscated filenames for the filenames of the software modules;
pass the obfuscated filenames as arguments to a linker module; and
generate, by the linker module, a software image file to include links to debugging files, the links including the obfuscated filenames.

2. The information handling system of claim 1 , wherein the one-way deterministic function utilizes at least an original filename of the source code file or the program as an input into the one-way deterministic function to generate the obfuscated filename.

3. The information handling system of claim 2 , wherein the one-way deterministic function utilizes at least a cryptographic salt as another input into the one-way deterministic function to generate the obfuscated filename.

4. The information handling system of claim 1 , wherein the one or more program modules are further executable by the one or more processors to generate a reverse-lookup file that associates the obfuscated filename with an original filename of the source code file or the program.

5. The information handling system of claim 1 , wherein:
the link to the debugging file in the program includes a directory pathway; and
links for each of a plurality of debugging files, corresponding to each of the source code files, include the directory pathway.

6. The information handling system of claim 1 , wherein the one-way deterministic function is a hash function.

7. The information handling system of claim 1 , wherein the program is one of a plurality of programs included in an executable binary file, wherein the executable binary file includes links to a plurality of debugging files, one debugging file for each of the plurality of programs.

8. The information handling system of claim 7 , wherein the executable binary file is a Basic Input/Output System (BIOS) file.

9. A method for obfuscating debugging filenames during a software build, the method comprising:
compile a source code file or a plurality of source code files into software modules;
pass file names of the software modules to a script;
generate, at least in part by the script, based at least in part on a one-way deterministic function, obfuscated filenames for the filenames of the software modules;
pass the obfuscated filenames as arguments to a linker module; and
generate, by the linker module, a software image file wherein the software image file is a Basic Input/Output System (BIOS) file, wherein the software image file includes links to debugging files, the links including the obfuscated filename.

10. The method of claim 9 , further comprising utilizing at least an original filename of the source code file or the program as an input into the one-way deterministic function to generate the obfuscated filename.

11. The method of claim 10 , utilizing a cryptographic salt as another input into the one-way deterministic function to generate the obfuscated filename.

12. The method of claim 9 , further comprising generating a reverse-lookup file that identifies the obfuscated filename with an original filename of the source code file or the program.

13. The method of claim 9 , wherein:
the program is one of a plurality of programs included in the BIOS file; and
the BIOS file includes links to a plurality of debugging files, one debugging file for each of the plurality of programs.

14. One or more non-transitory computer-readable media having programming instructions that are executable by one or more processors to perform acts comprising:
compiling a source code file or a plurality of source code files into software modules;
passing filenames of the software modules to a script;
generating, at least in part by the script and based at least in part on a one-way deterministic function, obfuscated filenames for the filenames of the software modules;
passing, by the script, the obfuscated filenames as arguments to a linker module; and
generating, by the linker module, a software image file wherein the software image file is a Basic Input/Output System (BIOS) file, the software image file including links to the debugging file in the program, the link including the obfuscated filename.

15. The one or more non-transitory computer-readable media of claim 14 , wherein the acts further comprise utilizing at least an original filename of the source code file or the program as an input into the one-way deterministic function to generate the obfuscated filename.

16. The one or more non-transitory computer-readable media of claim 15 , wherein the acts further comprise utilizing a cryptographic salt as another input into the one-way deterministic function to generate the obfuscated filename.

17. The one or more non-transitory computer-readable media of claim 16 , wherein the one-way deterministic function is a hash function.

18. The one or more non-transitory computer-readable media of claim 14 , wherein:
the program is one of a plurality of programs included in the BIOS file; and
the BIOS file includes links to a plurality of debugging files, one debugging file for each of the plurality of programs.

19. The one or more non-transitory computer-readable media of claim 14 , wherein:
the link to the debugging file in the program includes a directory pathway; and
links for each of a plurality of debugging files, corresponding to each of the source code files, include the directory pathway.

20. The one or more non-transitory computer-readable media of claim 14 , wherein the one-way deterministic function comprises a hash function.
