This is an experimental SAK filter that uses evdev and friends to:
|
||
|
|
1.) Signal when a SAK (currently hardcoded as Ctrl+Alt+DEL) is pressed
|
||
|
|
This signal is ONLY available to applications running as root
|
||
|
|
2.) Filter any SAK press events out, so that no non-root applications are aware of them if they occur.
|
||
|
|
In fact, even root applications will be unaware of the SAK press unless they are monitoring
|
||
|
|
the out-of-band SAK interface.
|
||
|
|
|
||
|
|
The interface is very simple. Listen on /tmp/ksocket-global/tsak and you will receive the null-terminated string "SAK\n\r" when the SAK is pressed.
|
||
|
|
Note that the string may be sent multiple times, especially if the SAK is held down.
