* 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.

* @scl_pin: GPIO pin ID to use for SCL
|
|
* @udelay: signal toggle delay. SCL frequency is (500 / udelay) kHz
|
|
* @timeout: clock stretching timeout in jiffies. If the slave keeps
|
|
* SCL low for longer than this, the transfer will time out.

|
* @sda_is_open_drain: SDA is configured as open drain, i.e. the pin
|
|
* isn't actively driven high when setting the output value high.
|
|
* gpio_get_value() must return the actual pin state even if the
|
|
* pin is configured as an output.
|
|
* @scl_is_open_drain: SCL is set up as open drain. Same requirements
|
|
* as for sda_is_open_drain apply.
|
|
* @scl_is_output_only: SCL output drivers cannot be turned off.
