Merge tag 'vmwgfx-next-2014-01-17' of git://people.freedesktop.org/~thomash/linux into drm-next
Pull request of 2014-01-17
Pull request for 3.14. One not so urgent fix, One huge device update.
The pull request corresponds to the patches sent out on dri-devel, except:
[PATCH 02/33], review tag typo pointed out by Matt Turner.
[PATCH 04/33], dropped. The new surface formats are never used.
The upcoming vmware svga2 hardware version 11 will introduce the concept
of "guest backed objects" or -resources. The device will in principle
get all
of its memory from the guest, which has big advantages from the device
point of view.
This means that vmwgfx contexts, shaders and surfaces need to be backed
by guest memory in the form of buffer objects called MOBs, presumably
short for MemoryOBjects, which are bound to the device in a special way.
This patch series introduces guest backed object support. Some new IOCTLs
are added to allocate these new guest backed object, and to optionally
provide
them with a backing MOB.
There is an update to the gallium driver that comes with this update, and
it will be pushed in the near timeframe presumably to a separate mesa branch
before merged to master.

drm/vmwgfx: Fix the driver for large dma addresses
With dma compliance / IOMMU support added to the driver in kernel 3.13,
the dma addresses can exceed 44 bits, which is what we support in
32-bit mode and with GMR1.
So in 32-bit mode and optionally in 64-bit mode, restrict the dma
addresses to 44 bits, and strip the old GMR1 code.

powerpc: Check return value of instance-to-package OF call
On PA-Semi firmware, the instance-to-package callback doesn't seem
to be implemented. We didn't check for error, however, thus
subsequently passed the -1 value returned into stdout_node to
thins like prom_getprop etc...
Thus caused the firmware to load values around 0 (physical) internally
as node structures. It somewhat "worked" as long as we had a NULL in the
right place (address 8) at the beginning of the kernel, we didn't "see"
the bug. But commit
5c0484e25ec03243d4c2f2d4416d4a13efc77f6a
"powerpc: Endian safe trampoline" changed the kernel entry point causing
that old bug to now cause a crash early during boot.
This fixes booting on PA-Semi board by properly checking the return
value from instance-to-package.

Investigating, I found that the inode->i_security was NULL, and the
dereference of it caused the oops.
in selinux_inode_permission():
isec = inode->i_security;
rc = avc_has_perm_noaudit(sid, isec->sid, isec->sclass, perms, 0, &avd);
Note, the crash came from stressing the deletion and reading of debugfs
files. I was not able to recreate this via normal files. But I'm not
sure they are safe. It may just be that the race window is much harder
to hit.
What seems to have happened (and what I have traced), is the file is
being opened at the same time the file or directory is being deleted.
As the dentry and inode locks are not held during the path walk, nor is
the inodes ref counts being incremented, there is nothing saving these
structures from being discarded except for an rcu_read_lock().
The rcu_read_lock() protects against freeing of the inode, but it does
not protect freeing of the inode_security_struct. Now if the freeing of
the i_security happens with a call_rcu(), and the i_security field of
the inode is not changed (it gets freed as the inode gets freed) then
there will be no issue here. (Linus Torvalds suggested not setting the
field to NULL such that we do not need to check if it is NULL in the
permission check).
Note, this is a hack, but it fixes the problem at hand. A real fix is
to restructure the destroy_inode() to call all the destructor handlers
from the RCU callback. But that is a major job to do, and requires a
lot of work. For now, we just band-aid this bug with this fix (it
works), and work on a more maintainable solution in the future.

since shrink_huge_zero_page() can free the huge_zero_page, and we have

page_table_lock and has checked pmd_same), it's possible for it to
answer yes the first time, but no to the second or third test. Change
all those last three to tests for NULL page.
(Note: this is not the same issue as trinity's DEBUG_PAGEALLOC BUG
in copy_page_rep with RSI:
ffff88009c422000, reported by Sasha Levin
in https://lkml.org/lkml/2013/3/29/103. I believe that one is due
to the source page being split, and a tail page freed, while copy
is in progress; and not a problem without DEBUG_PAGEALLOC, since
the pmd_same check will prevent a miscopy from being made visible.)
