MossBenchmark

This repository contains 26 programs used by Moss. If you want to know how to use this benchmark, please refer to Moss.

1.Adjustments to some programs

1.1 chown-8.2:

Before running chown, you must create a user mychown that belongs to a user group mychown.

1.2 vim-5.8:

①You need to download ncurses library and expect.

apt install libncurses-dev expect parallel

②You need to set timeout more than 1 second (in test.sh and generate_cov.py), because open file in vim cost some time.

③Vim use expect script, and it launch many vim-5.8 thread without tty. Take careful to close them. We have used cleanup script in vim-5.8 directory to do this. Please modify the path in cleanup.

1.3 bash-2.05:

You need to modify the path of lib in compile.sh.

1.4 make-3.79:

①You need to modify the path of lib in compile.sh.

②date-8.21 and make-3.79 have crisis. date-8.12 may change the system time which is used in make's testscripts. Don't run them together.

1.5 mkdir-5.2.1:

Moss use rsync to remove garbage files in /.

apt install rsync

1.6 gzip-1.2.4, gzip-1.3, bzip2-1.0.5, tar-1.14

Moss use chattr +/-i to keep /bin, /usr, and working directory unchanged.

1.7 postgresql-12.14

①Use "/postgresql-12.14" (absolute path) as working directory, or you need to change path in postgresql-12.14/path_generator/generate_cov.py and postgresql-12.14/cleanup to your path.

②Due to the impact of long comment blocks on parsing code, we use postgresql-12.14/deletecomments.py to delete all comments in the source code.

2. Key parameters in the debloating scripts:

• PROGNAME: The program name.
• version: The debloating strategy (3 is Moss, 2 is Moss-s1, 1 is Moss-s2, 0 is Moss-s3).
• debop_samplenum: The sample number of the second and third stages.
• domgad_samplenum: The sample number of the first stage.
• alphas: Alpha value (weight for attack surface reduction).
• ks: K value (for computing density values).
• betas: Beta value (weight for generality).
• DEBOP_DIR: The path of CovBlock_Stmt.
• DOMGAD_DIR: The path of CovPath.
• COV: The path of cov.
• iternum: The iteration number of each stage of Moss.
• realorcov: Use real or top program as the baseline.
