There is a possibility to retrieve user input keystroke data stored in the queue buffer via the EFI_SIMPLE_TEXT_INPUT_PROTOCOL pointer. To prevent exposure of the password string, clear the queue buffer by filling it with zeros after reading. Signed-off-by: Nick Wang <nick.wang@insyde.com>

2018-02-01MdeModulePkg/Ps2Kb: ReadKeyStrokeEx always return key stateRuiyu Ni1-1/+5
Today's implementation only return key state when there is key. But when user doesn't press any key, the key state cannot be returned. The patch changes the ReadKeyStrokeEx() to always return the key state even there is no key pressed.

2016-12-26MdeModulePkg Ps2KbDxe: Execute key notify func at TPL_CALLBACKStar Zeng1-0/+49
Current implementation executes key notify function in TimerHandler at TPL_NOTIFY. The code change is to make key notify function executed at TPL_CALLBACK to reduce the time occupied at TPL_NOTIFY. The code will signal KeyNotify process event if the key pressed matches any key registered and insert the KeyData to the EFI Key queue for notify, then the KeyNotify process handler will invoke key notify functions at TPL_CALLBACK.
