Andreas Kling	153ea704af	Add some basic signal support. ... It only works for sending a signal to a process that's in userspace code. We implement reception by synthesizing a PUSHA+PUSHF in the receiving process (operating on values in the TSS.) The TSS CS:EIP is then rerouted to the signal handler and a tiny return trampoline is constructed in a dedicated region in the receiving process. Also hacked up /bin/kill to be able to send arbitrary signals (kill -N PID)	2018-11-06 10:56:41 +01:00
Andreas Kling	3218f00099	Implement basic sys$kill() and add a /bin/kill ... All it can do right now is send SIGKILL which just murders the target task.	2018-10-31 01:06:57 +01:00
