Fix build failure due to hwirq.h needing smp_lock.h

Arnd Bergmann did an automated scripting run to find left-over instances
of <linux/smp_lock.h>, and had made it trigger it on the normal BKL use
of lock_kernel and unlock_lernel (and apparently release_kernel_lock and
reacquire_kernel_lock too, used by the scheduler).

That resulted in commit 451a3c24b013 ("BKL: remove extraneous #include
<smp_lock.h>").

However, hardirq.h was the only remaining user of the old
'kernel_locked()' interface, and Arnd's script hadn't checked for that.
So depending on your configuration and what header files had been
included, you would get errors like "implicit declaration of function
'kernel_locked'" during the build.

The right fix is not to just re-instate the smp_lock.h include - it is
to just remove 'kernel_locked()' entirely, since the only use was this
one special low-level detail.  Just make hardirq.h do it directly.

In fact this simplifies and clarifies the code, because some trivial
analysis makes it clear that hardirq.h only ever used _one_ of the two
definitions of kernel_locked(), so we can remove the other one entirely.

KVM: VMX: Fix host userspace gsbase corruption

We now use load_gs_index() to load gs safely; unfortunately this also
changes MSR_KERNEL_GS_BASE, which we managed separately.  This resulted
in confusion and breakage running 32-bit host userspace on a 64-bit kernel.

Fix by
- saving guest MSR_KERNEL_GS_BASE before we we reload the host's gs
- doing the host save/load unconditionally, instead of only when in guest
  long mode

removing one source of knowledge where things are in the kernel.

This is the second submit, discussion happened on this on first submit
and mostly concerned that this is just one hole of the sieve ...  but
one of the bigger ones.

Changing the permissions of at least System.map and vmlinux is also
required to fix the same set, but a packaging issue.

Target of this starter patch and follow ups is removing any kind of
kernel space address information leak from the kernel.

[ Side note: the default of root-only reading is the "safe" value, and
  it's easy enough to then override at any time after boot.  The /proc
  filesystem allows root to change the permissions with a regular
  chmod, so you can "revert" this at run-time by simply doing

    chmod og+r /proc/kallsyms

  as root if you really want regular users to see the kernel symbols.
  It does help some tools like "perf" figure them out without any
  setup, so it may well make sense in some situations.  - Linus ]

PCI: fix offset check for sysfs mmapped files

I just loaded 2.6.37-rc2 on my machines, and I noticed that X no longer starts.
Running an strace of the X server shows that it's doing this:

open("/sys/bus/pci/devices/0000:07:00.0/resource0", O_RDWR) = 10
mmap(NULL, 16777216, PROT_READ|PROT_WRITE, MAP_SHARED, 10, 0) = -1 EINVAL (Invalid argument)

This code seems to be asking for a shared read/write mapping of 16MB worth of
BAR0 starting at file offset 0, and letting the kernel assign a starting
address.  Unfortunately, this -EINVAL causes X not to start.  Looking into
dmesg, there's a complaint like so:

process "Xorg" tried to map 0x01000000 bytes at page 0x00000000 on 0000:07:00.0 BAR 0 (start 0x        96000000, size 0x         1000000)

...with the following code in pci_mmap_fits:

pci_start = (mmap_api == PCI_MMAP_SYSFS) ?
pci_resource_start(pdev, resno) >> PAGE_SHIFT : 0;
        if (start >= pci_start && start < pci_start + size &&
                        start + nr <= pci_start + size)

It looks like the logic here is set up such that when the mmap call comes via
sysfs, the check in pci_mmap_fits wants vma->vm_pgoff to be between the
resource's start and end address, and the end of the vma to be no farther than
the end.  However, the sysfs PCI resource files always start at offset zero,
which means that this test always fails for programs that mmap the sysfs files.
Given the comment in the original commit
3b519e4ea618b6943a82931630872907f9ac2c2b, I _think_ the old procfs files
require that the file offset be equal to the resource's base address when
mmapping.

I think what we want here is for pci_start to be 0 when mmap_api ==
PCI_MMAP_PROCFS.  The following patch makes that change, after which the Matrox
and Mach64 X drivers work again.

NLM: Fix a regression in lockd

Properly initialize sock_xprt.srcaddr in all cases)

Apparently, removing the 'transport->srcaddr.ss_family = family' from
xs_create_sock() triggers this due to nlmclnt_lookup_host() incorrectly
initialising the srcaddr family to AF_UNSPEC.

capabilities/syslog: open code cap_syslog logic to fix build failure

The addition of CONFIG_SECURITY_DMESG_RESTRICT resulted in a build
failure when CONFIG_PRINTK=n.  This is because the capabilities code
which used the new option was built even though the variable in question
didn't exist.

The patch here fixes this by moving the capabilities checks out of the
LSM and into the caller.  All (known) LSMs should have been calling the
capabilities hook already so it actually makes the code organization
better to eliminate the hook altogether.

Fix gcc 4.5.1 miscompiling drivers/char/i8k.c (again)

The fix in commit 6b4e81db2552 ("i8k: Tell gcc that *regs gets
clobbered") to work around the gcc miscompiling i8k.c to add "+m
(*regs)" caused register pressure problems and a build failure.

Changing the 'asm' statement to 'asm volatile' instead should prevent
that and works around the gcc bug as well, so we can remove the "+m".

[ Background on the gcc bug: a memory clobber fails to mark the function
  the asm resides in as non-pure (aka "__attribute__((const))"), so if
  the function does nothing else that triggers the non-pure logic, gcc
  will think that that function has no side effects at all. As a result,
  callers will be mis-compiled.

  Adding the "+m" made gcc see that it's not a pure function, and so
  does "asm volatile". The problem was never really the need to mark
  "*regs" as changed, since the memory clobber did that part - the
  problem was just a bug in the gcc "pure" function analysis  - Linus ]

Steven Whitehouse [Wed, 3 Nov 2010 20:01:07 +0000 (20:01 +0000)]
GFS2: Fix inode deallocation race

This area of the code has always been a bit delicate due to the
subtleties of lock ordering. The problem is that for "normal"
alloc/dealloc, we always grab the inode locks first and the rgrp lock
later.

In order to ensure no races in looking up the unlinked, but still
allocated inodes, we need to hold the rgrp lock when we do the lookup,
which means that we can't take the inode glock.

The solution is to borrow the technique already used by NFS to solve
what is essentially the same problem (given an inode number, look up
the inode carefully, checking that it really is in the expected
state).

We cannot do that directly from the allocation code (lock ordering
again) so we give the job to the pre-existing delete workqueue and
carry on with the allocation as normal.

If we find there is no space, we do a journal flush (required anyway
if space from a deallocation is to be released) which should block
against the pending deallocations, so we should always get the space
back.
