thanks for the confirmation.

What wait* functions even *care* that your LSM was what killed it?
If you're caring about somehow notifying userspace that it was your
Hi,
I'm working in a LSM whose goal is to detect and mitigate fork brute force
attacks against vulnerable userspace applications. The detection and
mitigation works as expected by I'm stuck at this point.
The mitigation method used is to kill all the offending tasks involved in
the attack. To do

Hi all,
I have a driver that is bound to a platform device. It creates a
miscdevice to interact with user space. And it has a "global" structure

Hi Everyone,
I tried to build the kernel myself for the first a few days ago. While the
build was successful, I am unable to boot to it. After grub I get a
blinking cursor for 15 to 30 minutes, and then a message that says "Please
reboot and select proper boot device."
Since ubuntu ships with a
