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.

Claims

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.
