I am using udev in order to create a kiosk mode. I want to block devices which fit a certain vid pid. I want to filter system calls anyway because I dont know which devices are entered and I want to avoid devices which will do unusual things like rubber ducky.
What do you mean by filtering system calls in scripts- is it needed when the user can influence actions commited in the script ? בתאריך יום ב׳, 14 בדצמ׳ 2020, 16:45, מאת Greg KH < gre...@linuxfoundation.org>: > On Mon, Dec 14, 2020 at 04:30:58PM +0200, Adi Ml wrote: > > Hi, > > Is there some way to detect which system calls, I am using in udev (in > > order to filter it)? > > I don't understand, if you don't know what system calls you are needing, > why do you need to filter anything?
