If this option is disabled, you allow userspace (root) access to all

When a user program crashes due to an exception, the kernel can

print a brief message explaining what the problem was. This is
|
|
sometimes helpful for debugging but serves no purpose on a
|
|
production system. Most people should say N here.
|
|
|
|
In addition, you need to pass user_debug=N on the kernel command
|
|
line to enable this feature. N consists of the sum of:
|
|
|
|
1 - undefined instruction events
|
|
2 - system calls
|
|
4 - invalid data aborts
|
|
8 - SIGSEGV faults
