+	  By design some architectures do not allow for protecting memory
+	  pages against execution or even if they do, Linux does not make
+	  use of this feature.  In practice this means that if a page is
+	  readable (such as the stack or heap) it is also executable.
+
+	  There is a well known exploit technique that makes use of this
+	  fact and a common programming mistake where an attacker can
+	  introduce code of his choice somewhere in the attacked program's
+	  memory (typically the stack or the heap) and then execute it.
+
+	  If the attacked program was running with different (typically
+	  higher) privileges than that of the attacker, then he can elevate
+	  his own privilege level (e.g. get a root shell, write to files for
+	  which he does not have write access to, etc).
+
+	  Enabling this option will let you choose from various features
+	  that prevent the injection and execution of 'foreign' code in
+	  a program.
+
+	  This will also break programs that rely on the old behaviour and

+	  the GCC trampolines.
+
+	  If you enabled CONFIG_PAX_PAGEEXEC or CONFIG_PAX_SEGMEXEC then

+
+	  As a remedy you can say Y here and use the 'chpax' or 'paxctl'

+

+	  be achieved by not using libc5 (which relies on the kernel
+	  signal handler return code) and not using or rewriting programs

+	  an already existing ELF library that does not have position

+	  writable and copy his code there.  While protecting against

+	  need to relocate their code).  If you are sure this is your case,
+	  then disable this option otherwise be careful as you may not even

+	  Many if not most exploit techniques rely on the knowledge of
+	  certain addresses in the attacked program.  The following options
+	  will allow the kernel to apply a certain amount of randomization
+	  to specific parts of the program thereby forcing an attacker to
+	  guess them in most cases.  Any failed guess will most likely crash
+	  the attacked program which allows the kernel to detect such attempts
+	  and react on them.  PaX itself provides no reaction mechanisms,
+	  instead it is strongly encouraged that you make use of Nergal's
+	  segvguard (ftp://ftp.pl.openwall.com/misc/segvguard/) or grsecurity's
+	  (http://www.grsecurity.net/) built-in crash detection features or
+	  develop one yourself.
+
+	  By saying Y here you can choose to randomize the following areas:
+	   - top of the task's kernel stack
+	   - top of the task's userland stack
+	   - base address for mmap() requests that do not specify one
+	     (this includes all libraries)
+	   - base address of the main executable
+
+	  It is strongly recommended to say Y here as address space layout
+	  randomization has negligible impact on performance yet it provides
+	  a very effective protection.
+

+	  By saying Y here the kernel will randomize every task's kernel
+	  stack on every system call.  This will not only force an attacker
+	  to guess it but also prevent him from making use of possible
+	  leaked information about it.
+
+	  Since the kernel stack is a rather scarce resource, randomization
+	  may cause unexpected stack overflows, therefore you should very
+	  carefully test your system.  Note that once enabled in the kernel
+	  configuration, this feature cannot be disabled on a per file basis.
+
+config PAX_RANDUSTACK
+	bool "Randomize user stack base"

+	help
+	  By saying Y here the kernel will randomize every task's userland
+	  stack.  The randomization is done in two steps where the second
+	  one may apply a big amount of shift to the top of the stack and
+	  cause problems for programs that want to use lots of memory (more
+	  than 2.5 GB if SEGMEXEC is not active, or 1.25 GB when it is).
+	  For this reason the second step can be controlled by 'chpax' or
+	  'paxctl' on a per file basis.
+
+config PAX_RANDMMAP
+	bool "Randomize mmap() base"
+	depends on PAX_ASLR
+	help
+	  By saying Y here the kernel will use a randomized base address for
+	  mmap() requests that do not specify one themselves.  As a result
+	  all dynamically loaded libraries will appear at random addresses
+	  and therefore be harder to exploit by a technique where an attacker
+	  attempts to execute library code for his purposes (e.g. spawn a
+	  shell from an exploited program that is running at an elevated
+	  privilege level).
+
+	  Furthermore, if a program is relinked as a dynamic ELF file, its
+	  base address will be randomized as well, completing the full
+	  randomization of the address space layout.  Attacking such programs
+	  becomes a guess game.  You can find an example of doing this at
+	  http://pax.grsecurity.net/et_dyn.tar.gz and practical samples at
+	  http://www.grsecurity.net/grsec-gcc-specs.tar.gz .

+
+	  This is especially useful for programs whose runtime is short, long

+
+	  The tradeoff is that some virtualization solutions may experience
+	  a huge slowdown and therefore you should not enable this feature
+	  for kernels meant to run in such environments.  Whether a given VM
+	  solution is affected or not is best determined by simply trying it
+	  out, the performance impact will be obvious right on boot as this

+	  overflows can normally occur due to bugs only and are often, if
+	  not always, exploitable.
+
+	  The tradeoff is that data structures protected by an overflowed
+	  refcount will never be freed and therefore will leak memory.  Note
+	  that this leak also happens even without this protection but in
+	  that case the overflow can eventually trigger the freeing of the
+	  data structure while it is still being used elsewhere, resulting

+
+	  Specifically, this checking prevents information leaking from the
+	  kernel heap during kernel to userland copies (if the kernel heap

+	  overflows during userland to kernel copies.  Only objects belonging
+	  to explictly marked slub types are allowed to be copied at all.
+
+	  Note that the current implementation provides the strictest checks
