[PATCH] uml: mechanical tidying after random MACs change

Mechanical, hopefully non-functional changes stemming from
setup_etheraddr always succeeding now that it always assigns a MAC,
either from the command line or generated randomly:
   the test of the return of setup_etheraddr is removed, and code
dependent on it succeeding is now unconditional
   setup_etheraddr can now be made void
   struct uml_net.have_mac is now always 1, so tests of it can be
similarly removed, and uses of it can be replaced with 1
   struct uml_net.have_mac is no longer used, so it can be removed
   struct uml_net_private.have_mac is copied from struct uml_net, so
it is always 1
   tests of uml_net_private.have_mac can be removed
   uml_net_private.have_mac can now be removed
   the only call to dev_ip_addr was removed, so it can be deleted

It also turns out that setup_etheraddr is called only once, from the same
file, so it can be static and its declaration removed from net_kern.h.

Similarly, set_ether_mac is defined and called only from one file.

Finally, setup_etheraddr and set_ether_mac were moved to avoid needing forward
declarations.

[PATCH] uml: assign random MACs to interfaces if necessary

Assign a random MAC to an ethernet interface if one was not provided on the
command line.  This became pressing when distros started bringing interfaces
up before assigning IPs to them.  The previous pattern of assigning an IP then
bringing it up allowed the MAC to be generated from the first IP assigned.
However, once the thing is up, it's probably a bad idea to change the MAC, so
the MAC stayed initialized to fe:fd:0:0:0:0.

Now, if there is no MAC from the command line, one is generated.  We use the
microseconds from gettimeofday (20 bits), plus the low 12 bits of the pid to
seed the random number generator.  random() is called twice, with 16 bits of
each result used.  I didn't want to have to try to fill in 32 bits optimally
given an arbitrary RAND_MAX, so I just assume that it is greater than 65536
and use 16 bits of each random() return.

There is also a bit of reformatting and whitespace cleanup here.

[PATCH] convert i386 Summit subarch to use SRAT info for apicid_to_node calls

Convert the i386 summit subarch apicid_to_node to use node information
provided by the SRAT.  It was discussed a little on LKML a few weeks ago
and was seen as an acceptable fix.  The current way of obtaining the nodeid

 static inline int apicid_to_node(int logical_apicid)
 {
   return logical_apicid >> 5;
 }

is just not correct for all summit systems/bios.  Assuming the apicid
matches the Linux node number require a leap of faith that the bios mapped
out the apicids a set way.  Modern summit HW (IBM x460) does not layout its
bios in the manner for various reasons and is unable to boot i386 numa.

The best way to get the correct apicid to node information is from the SRAT
table during boot.  It lays out what apicid belongs to what node.  I use
this information to create a table for use at run time.

[PATCH] SELinux: support mls categories for context mounts

Allows commas to be embedded into context mount options (i.e.  "-o
context=some_selinux_context_t"), to better support multiple categories,
which are separated by commas and confuse mount.

For example, with the current code:

  mount -t iso9660 /dev/cdrom /media/cdrom -o \
  ro,context=system_u:object_r:iso9660_t:s0:c1,c3,c4,exec

The context option that will be interpreted by SELinux is
context=system_u:object_r:iso9660_t:s0:c1

instead of
context=system_u:object_r:iso9660_t:s0:c1,c3,c4

The options that will be passed on to the file system will be
ro,c3,c4,exec.

The proposed solution is to allow/require the SELinux context option
specified to mount to use quotes when the context contains a comma.

This patch modifies the option parsing in parse_opts(), contained in
mount.c, to take options after finding a comma only if it hasn't seen a
quote or if the quotes are matched.  It also introduces a new function that
will strip the quotes from the context option prior to translation.  The
quotes are replaced after the translation is completed to insure that in
the event the raw context contains commas the kernel will be able to
interpret the correct context.

[PATCH] mm: fix a race condition under SMC + COW

Failing context is a multi threaded process context and the failing
sequence is as follows.

One thread T0 doing self modifying code on page X on processor P0 and
another thread T1 doing COW (breaking the COW setup as part of just
happened fork() in another thread T2) on the same page X on processor P1.
T0 doing SMC can endup modifying the new page Y (allocated by the T1 doing
COW on P1) but because of different I/D TLB's, P0 ITLB will not see the new
mapping till the flush TLB IPI from P1 is received.  During this interval,
if T0 executes the code created by SMC it can result in an app error (as
ITLB still points to old page X and endup executing the content in page X
rather than using the content in page Y).

Fix this issue by first clearing the PTE and flushing it, before updating
it with new entry.

Hugh sayeth:

  I was a bit sceptical, in the habit of thinking that Self Modifying Code
  must look such issues itself: but I guess there's nothing it can do to avoid
  this one.

  Fair enough, what you're changing it to is pretty much what powerpc and
  s390 were already doing, and is a more robust way of proceeding, consistent
  with how ptes are set everywhere else.

  The ptep_clear_flush is a bit heavy-handed (it's anxious to return the pte
  that was atomically cleared), but we'd have to wander through lots of arches
  to get the right minimal behaviour.  It'd also be nice to eliminate
  ptep_establish completely, now only used to define other macros/inlines: it
  always seemed obfuscation to me, what you've got there now is clearer.
  Let's put those cleanups on a TODO list.

[NET]: Move netlink interface bits to linux/if_link.h.

Moving netlink interface bits to linux/if.h is rather troublesome for
applications including both linux/if.h (which was changed to be included
from linux/rtnetlink.h automatically) and net/if.h.

[XFRM]: Do not add a state whose SPI is zero to the SPI hash.

SPI=0 is used for acquired IPsec SA and MIPv6 RO state.
Such state should not be added to the SPI hash
because we do not care about it on deleting path.

followed by __u16 num.  We want to search by pair, so we combine the keys into
a single 32bit value and compare with 32bit value read from &...->dport.
* on 64bit targets we combine comparisons with pair of adjacent __be32
fields in the same way.

Make sure that we don't mix those values with anything else and that pairs
we form them from have correct types.
