| """ |
| Runs the scrashme syscalls test suite. This test mode will exercise |
| kernel syscalls randomically, or in a sequential fashion. |
| |
| @note: As of the current version shipped, scrashme does support the |
| following options: |
| |
| --mode must be one of random, rotate, regval, struct, or capcheck |
| --mode=random : pass random values in registers to random syscalls |
| -s#: use # as random seed. |
| |
| --mode=rotate : rotate value through all register combinations |
| -k: pass kernel addresses as arguments. |
| -u: pass userspace addresses as arguments. |
| -x#: use value as register arguments. |
| -z: use all zeros as register parameters. |
| -Sr: pass struct filled with random junk. |
| -Sxx: pass struct filled with hex value xx. |
| |
| --mode=capcheck: check syscalls that call capable() return -EPERM. |
| |
| -b#: begin at offset #. |
| -c#: target syscall # only. |
| -N#: do # syscalls then exit. |
| -P: poison buffers before calling syscall, and check afterwards. |
| -p: pause after syscall. |
