-Subject: [PATCH 2/2] swaponoff: add uuid/label support
-
-This allows swapon -a enable swap when the swap partition is specified by
-either UUID=... or LABEL=... in /etc/fstab
-
-We could have made a separate config option for this but it makes sense
-to have it with MOUNT_LABEL as you will need that to parse the rest of
-fstab anyway.

++	  If you say Y here, many of the features of grsecurity will be

++	  of an increased chance of incompatibilities with rare software
++	  on your machine.  Since this security level enables PaX, you should
++	  view <http://pax.grsecurity.net> and read about the PaX
++	  project.  While you are there, download chpax and run it on
++	  binaries that cause problems with PaX.  Also remember that
++	  since the /proc restrictions are enabled, you must run your
++	  identd as gid 1001.  This security level enables the following 
++	  features in addition to those listed in the low and medium 
++	  security levels:

++	help
++	  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
++	  expect that dynamically allocated memory via the malloc() family
++	  of functions is executable (which it is not).  Notable examples

++	  signal handler return code generated by the kernel itself and
++	  the GCC trampolines.
++
++	  If you enabled CONFIG_PAX_PAGEEXEC or CONFIG_PAX_SEGMEXEC then
++	  such programs will no longer work under your kernel.
++
++	  As a remedy you can say Y here and use the 'chpax' or 'paxctl'
++	  utilities to enable trampoline emulation for the affected programs
++	  yet still have the protection provided by the non-executable pages.
++
++	  On parisc you MUST enable this option and EMUSIGRT as well, otherwise

++
++	  Alternatively you can say N here and use the 'chpax' or 'paxctl'
++	  utilities to disable CONFIG_PAX_PAGEEXEC and CONFIG_PAX_SEGMEXEC
++	  for the affected files.
++
++	  NOTE: enabling this feature *may* open up a loophole in the
++	  protection provided by non-executable pages that an attacker
++	  could abuse.  Therefore the best solution is to not have any
++	  files on your system that would require this option.  This can
++	  be achieved by not using libc5 (which relies on the kernel
++	  signal handler return code) and not using or rewriting programs
++	  that make use of the nested function implementation of GCC.
++	  Skilled users can just fix GCC itself so that it implements

++	  not even boot.
++
++	  NOTE: this feature cannot be disabled on a per executable basis

++	help
++	  Non-executable pages and mprotect() restrictions are effective
++	  in preventing the introduction of new executable code into an
++	  attacked task's address space.  There remain only two venues
++	  for this kind of attack: if the attacker can execute already
++	  existing code in the attacked task then he can either have it
++	  create and mmap() a file containing his code or have it mmap()
++	  an already existing ELF library that does not have position
++	  independent code in it and use mprotect() on it to make it
++	  writable and copy his code there.  While protecting against
++	  the former approach is beyond PaX, the latter can be prevented
++	  by having only PIC ELF libraries on one's system (which do not
++	  need to relocate their code).  If you are sure this is your case,
++	  then enable this option otherwise be careful as you may not even
++	  be able to boot or log on your system (for example, some PAM
++	  modules are erroneously compiled as non-PIC by default).
++
++	  NOTE: if you are using dynamic ELF executables (as suggested
++	  when using ASLR) then you must have made sure that you linked
++	  your files using the PIC version of crt1 (the et_dyn.tar.gz package

++	  sparc and sparc64, otherwise your system would not even boot.
++
++	  NOTE: this feature *does* open up a loophole in the protection

++	help
++	  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.
++
++	  NOTE: you can use the 'chpax' or 'paxctl' utilities to control
++	  this feature on a per file basis.
++
++config PAX_RANDKSTACK
++	bool "Randomize kernel stack base"
++	depends on PAX_ASLR && X86_TSC && X86_32
++	help
++	  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"
++	depends on PAX_ASLR
++	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 .

++config PAX_MEMORY_SANITIZE
++	bool "Sanitize all freed memory"
++	help
++	  By saying Y here the kernel will erase memory pages as soon as they
++	  are freed.  This in turn reduces the lifetime of data stored in the
++	  pages, making it less likely that sensitive information such as
++	  passwords, cryptographic secrets, etc stay in memory for too long.
++
++	  This is especially useful for programs whose runtime is short, long
++	  lived processes and the kernel itself benefit from this as long as
++	  they operate on whole memory pages and ensure timely freeing of pages
++	  that may hold sensitive information.
++
++	  The tradeoff is performance impact, on a single CPU system kernel
++	  compilation sees a 3% slowdown, other systems and workloads may vary
++	  and you are advised to test this feature on your expected workload
++	  before deploying it.
++
++	  Note that this feature does not protect data stored in live pages,

++
++config PAX_MEMORY_UDEREF
++	bool "Prevent invalid userland pointer dereference"
++	depends on X86_32 && !UML_X86 && !XEN
++	help
++	  By saying Y here the kernel will be prevented from dereferencing
++	  userland pointers in contexts where the kernel expects only kernel
++	  pointers.  This is both a useful runtime debugging feature and a
++	  security measure that prevents exploiting a class of kernel bugs.
++
++	  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
++	  mechanism engages from very early on.  A good rule of thumb is that
++	  VMs running on CPUs without hardware virtualization support (i.e.,
++	  the majority of IA-32 CPUs) will likely experience the slowdown.

++config PAX_REFCOUNT
++	bool "Prevent various kernel object reference counter overflows"
++	depends on GRKERNSEC && (X86 || SPARC64)
++	help
++	  By saying Y here the kernel will detect and prevent overflowing
++	  various (but not all) kinds of object reference counters.  Such
++	  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
++	  in the exploitable situation that this feature prevents.
++
++	  Since this has a negligible performance impact, you should enable
++	  this feature.
++
++config PAX_USERCOPY

++	depends on X86 || PPC32 || PPC64 || SPARC32 || SPARC64

++	help
++	  By saying Y here the kernel will enforce the size of heap objects
++	  when they are copied in either direction between the kernel and
++	  userland, even if only a part of the heap object is copied.
++
++	  Specifically, this checking prevents information leaking from the
++	  kernel heap during kernel to userland copies (if the kernel heap
++	  object is otherwise fully initialized) and prevents kernel heap
++	  overflows during userland to kernel copies.
++
++	  Note that the current implementation provides the strictest checks
