Pretty sure you can do that without modifying the kernel. You can get a complete map of valid memory segments via /proc/pid/map, and things like gdb peek into the memory of child processes all the time.

Hi All,
Is there a max number of slabs that can be used per kernel module? I'm having a tough time finding out that kind of information, but the array 'node_zonelists' (mmzone.h) has a size of 5. I just want to avoid buffer overruns and other bad stuff.

Question may seem illogical but I still need clarification.
Can we debug kernel modules loaded on my target system using kdb / kgdb without using any other system or remote debugging?
In other words my question is can we use kdb/kgdb to debug kernel modules running on same system? (2 Replies)

UUID(3) Libuuid API UUID(3)
NAME
uuid - DCE compatible Universally Unique Identifier library
SYNOPSIS
#include <uuid/uuid.h>
DESCRIPTION
The UUID library is used to generate unique identifiers for objects that may be accessible beyond the local system. This library generates
UUIDs compatible with those created by the Open Software Foundation (OSF) Distributed Computing Environment (DCE) utility uuidgen.
The UUIDs generated by this library can be reasonably expected to be unique within a system, and unique across all systems. They could be
used, for instance, to generate unique HTTP cookies across multiple web servers without communication between the servers, and without fear
of a name clash.
