00fab2350e s390/zcrypt: multiple zcrypt device nodes support
This patch is an extension to the zcrypt device driver to provide,
support and maintain multiple zcrypt device nodes. The individual
zcrypt device nodes can be restricted in terms of crypto cards,
domains and available ioctls. Such a device node can be used as a
base for container solutions like docker to control and restrict
the access to crypto resources.

The handling is done with a new sysfs subdir /sys/class/zcrypt.
Echoing a name (or an empty sting) into the attribute "create" creates
a new zcrypt device node. In /sys/class/zcrypt a new link will appear
which points to the sysfs device tree of this new device. The
attribute files "ioctlmask", "apmask" and "aqmask" in this directory
are used to customize this new zcrypt device node instance. Finally
the zcrypt device node can be destroyed by echoing the name into
/sys/class/zcrypt/destroy. The internal structs holding the device
info are reference counted - so a destroy will not hard remove a
device but only marks it as removable when the reference counter drops
to zero.

The mask values are bitmaps in big endian order starting with bit 0.
So adapter number 0 is the leftmost bit, mask is 0x8000...  The sysfs
attributes accept 2 different formats:
* Absolute hex string starting with 0x like "0x12345678" does set
  the mask starting from left to right. If the given string is shorter
  than the mask it is padded with 0s on the right. If the string is
  longer than the mask an error comes back (EINVAL).
* Relative format - a concatenation (done with ',') of the
  terms +<bitnr>[-<bitnr>] or -<bitnr>[-<bitnr>]. <bitnr> may be any
  valid number (hex, decimal or octal) in the range 0...255. Here are
  some examples:
    "+0-15,+32,-128,-0xFF"
    "-0-255,+1-16,+0x128"
    "+1,+2,+3,+4,-5,-7-10"

A simple usage examples:

  # create new zcrypt device 'my_zcrypt':
  echo "my_zcrypt" >/sys/class/zcrypt/create
  # go into the device dir of this new device
  echo "my_zcrypt" >create
  cd my_zcrypt/
  ls -l
  total 0
  -rw-r--r-- 1 root root 4096 Jul 20 15:23 apmask
  -rw-r--r-- 1 root root 4096 Jul 20 15:23 aqmask
  -r--r--r-- 1 root root 4096 Jul 20 15:23 dev
  -rw-r--r-- 1 root root 4096 Jul 20 15:23 ioctlmask
  lrwxrwxrwx 1 root root    0 Jul 20 15:23 subsystem -> ../../../../class/zcrypt
  ...
  # customize this zcrypt node clone
  # enable only adapter 0 and 2
  echo "0xa0" >apmask
  # enable only domain 6
  echo "+6" >aqmask
  # enable all 256 ioctls
  echo "+0-255" >ioctls
  # now the /dev/my_zcrypt may be used
  # finally destroy it
  echo "my_zcrypt" >/sys/class/zcrypt/destroy

Please note that a very similar 'filtering behavior' also applies to
the parent z90crypt device. The two mask attributes apmask and aqmask
in /sys/bus/ap act the very same for the z90crypt device node. However
the implementation here is totally different as the ap bus acts on
bind/unbind of queue devices and associated drivers but the effect is
still the same. So there are two filters active for each additional
zcrypt device node: The adapter/domain needs to be enabled on the ap
bus level and it needs to be active on the zcrypt device node level.

e80d4af0a3 s390/pkey: Introduce pkey kernel module
This patch introcudes a new kernel module pkey which is providing
protected key handling and management functions. The pkey API is
available within the kernel for other s390 specific code to create
and manage protected keys. Additionally the functions are exported
to user space via IOCTL calls. The implementation makes extensive
use of functions provided by the zcrypt device driver. For
generating protected keys from secure keys there is also a CEX
coprocessor card needed.

0d025d271e mm/usercopy: get rid of CONFIG_DEBUG_STRICT_USER_COPY_CHECKS
There are three usercopy warnings which are currently being silenced for
gcc 4.6 and newer:

1) "copy_from_user() buffer size is too small" compile warning/error

   This is a static warning which happens when object size and copy size
   are both const, and copy size > object size.  I didn't see any false
   positives for this one.  So the function warning attribute seems to
   be working fine here.

   Note this scenario is always a bug and so I think it should be
   changed to *always* be an error, regardless of
   CONFIG_DEBUG_STRICT_USER_COPY_CHECKS.

2) "copy_from_user() buffer size is not provably correct" compile warning

   This is another static warning which happens when I enable
   __compiletime_object_size() for new compilers (and
   CONFIG_DEBUG_STRICT_USER_COPY_CHECKS).  It happens when object size
   is const, but copy size is *not*.  In this case there's no way to
   compare the two at build time, so it gives the warning.  (Note the
   warning is a byproduct of the fact that gcc has no way of knowing
   whether the overflow function will be called, so the call isn't dead
   code and the warning attribute is activated.)

   So this warning seems to only indicate "this is an unusual pattern,
   maybe you should check it out" rather than "this is a bug".

   I get 102(!) of these warnings with allyesconfig and the
   __compiletime_object_size() gcc check removed.  I don't know if there
   are any real bugs hiding in there, but from looking at a small
   sample, I didn't see any.  According to Kees, it does sometimes find
   real bugs.  But the false positive rate seems high.

3) "Buffer overflow detected" runtime warning

   This is a runtime warning where object size is const, and copy size >
   object size.

All three warnings (both static and runtime) were completely disabled
for gcc 4.6 with the following commit:

  2fb0815c9e ("gcc4: disable __compiletime_object_size for GCC 4.6+")

That commit mistakenly assumed that the false positives were caused by a
gcc bug in __compiletime_object_size().  But in fact,
__compiletime_object_size() seems to be working fine.  The false
positives were instead triggered by #2 above.  (Though I don't have an
explanation for why the warnings supposedly only started showing up in
gcc 4.6.)

So remove warning #2 to get rid of all the false positives, and re-enable
warnings #1 and #3 by reverting the above commit.

Furthermore, since #1 is a real bug which is detected at compile time,
upgrade it to always be an error.

Having done all that, CONFIG_DEBUG_STRICT_USER_COPY_CHECKS is no longer
needed.

  2) switch_amode == 1 && s390_noexec == 0
  3) switch_amode == 1 && s390_noexec == 1
They get replaced by
  1) user_mode == HOME_SPACE_MODE
  2) user_mode == PRIMARY_SPACE_MODE
  3) user_mode == SECONDARY_SPACE_MODE
The new kernel parameter user_mode=[primary,secondary,home] lets
you choose the address space mode the user space processes should
use. In addition the CONFIG_S390_SWITCH_AMODE config option
is removed.
