"""
|
|
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.
