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

of memory, including kernel and userspace memory. Accidental

access to this is obviously disastrous, but specific access can

be used by people debugging the kernel.

If this option is switched on, the /dev/mem file only allows

userspace access to memory mapped peripherals.

help

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
|
|
16 - SIGBUS faults

This option influences the normal decompressor output for

multiplatform kernels. Normally, multiplatform kernels disable

decompressor output because it is not possible to know where to

send the decompressor output.

When this option is set, the selected DEBUG_LL output method

will be re-used for normal decompressor output on multiplatform

kernels.

This option helps catch unintended modifications to loadable

kernel module's text and read-only data. It also prevents execution

of module data. Such protection may interfere with run-time code
|

patching and dynamic kernel tracing - and they might also protect

|
against certain classes of kernel exploits.
|
|
If in doubt, say "N".
