Auxiliary vectors

According to getauxval(3), AUXV (auxiliary vector) is a mechanism that the kernel's ELF binary loader uses to pass certain information to user space when a program is executed. The contents can be obtained from /proc/self/auxv, through getauxval(3), or by setting LD_SHOW_AUXV=1 environment variable when running a program.

Auxiliary vectors obtained by LD_SHOW_AUXV=1 /bin/true:
