* 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.

* 11/01/01 - jbarnes - initial revision

* 9/10/04 - Christoph Lameter - remove interrupt support

* 9/17/04 - jbarnes - remove test program, move some #defines to the driver

* Breakdown of the ioctl's available. An 'optional' next to the command
|
|
* indicates that supporting this command is optional, while 'required'
|
|
* commands must be implemented if conformance is desired.
|
|
*
|
|
* MMTIMER_GETOFFSET - optional
|
|
* Should return the offset (relative to the start of the page where the
|
|
* registers are mapped) for the counter in question.
|
|
*
|
|
* MMTIMER_GETRES - required
|
|
* The resolution of the clock in femto (10^-15) seconds
|
|
*
|
|
* MMTIMER_GETFREQ - required
|
|
* Frequency of the clock in Hz
|
|

|
|
* MMTIMER_GETBITS - required
|
|
* Number of bits in the clock's counter
|
|
*
|
|
* MMTIMER_MMAPAVAIL - required
|
|
* Returns nonzero if the registers can be mmap'd into userspace, 0 otherwise
|
|
*
|
|
* MMTIMER_GETCOUNTER - required
|
|
* Gets the current value in the counter
