[$] Handling brute force attacks in the kernel

A number of different attacks against Linux systems rely on brute-forcetechniques using the fork()system call, so a new Linux security module (LSM), called "Brute", has been created todetect and thwart such attacks.Repeated fork() calls can be used for various types ofattacks, such as exploiting the StackClash vulnerability or Heartbleed-style flaws.Version 6 of the Brute patch set was recentlypostedand looks like it might be heading toward the mainline.
