Restrict

The restrict library restricts the open(), open64() and fopen() calls to only allow opening "allowed" files. Compile with::

./compile

Examples of usage::

LD_PRELOAD=./restrict.so touch test_file
LD_PRELOAD=./restrict.so cat test_file

How it Works

It preloads the open(), open64() and fopen() libc calls using the LD_PRELOAD mechanism. This means that static binaries, as well as accessing files by other means than through open/open64/fopen will not be checked.
