Different Compilers

Type of compiler

In Kernel Exploitation Stage, Compiler do matter in fact.

They compile exploit to execute, and the system can excute it with specific compiler.

Changing some line in kernel exploit code in 37292.c for clang compiler, not gcc.

    # lib = system("gcc -fPIC -shared -o /tmp/ofs-lib.so /tmp/ofs-lib.c -ldl -w");
    lib = system("cc -fPIC -shared -o /tmp/ofs-lib.so /tmp/ofs-lib.c -ldl -w");

If not compiled by the compiler that the system has, the exploit will not work!!!
