* 0day explit mitigation * Memory corruption prevention * Privilege escalation prevention * Buffer over flow prevention * File System corruption defense * Thread escape prevention This may very well be the most intensive inclusion to BrooklynR. This will not be part of an x86 suite nor it will be released as tool kit. The security core toolkit will remain part of kernel base.

/*
|
|
* The shmid64_ds structure for x86 architecture.
|
|
* Note extra padding because this structure is passed back and forth
|
|
* between kernel and user space.
|
|
*
|
|
* shmid64_ds was originally meant to be architecture specific, but
|
|
* everyone just ended up making identical copies without specific
|
|
* optimizations, so we may just as well all use the same one.
|
|
*
|
|
* 64 bit architectures typically define a 64 bit __kernel_time_t,
|
|
* so they do not need the first two padding words.
|
|
* On big-endian systems, the padding is in the wrong place.
|
|
*
|
|
*
|
|
* Pad space is left for:
|
|
* - 64-bit time_t to solve y2038 problem
|
|
* - 2 miscellaneous 32-bit values
