      xfs: increase number of ACL entries for V5 superblocks · 0a8aa193
      由 Dave Chinner 提交于 
      The limit of 25 ACL entries is arbitrary, but baked into the on-disk
format.  For version 5 superblocks, increase it to the maximum nuber
of ACLs that can fit into a single xattr.

      xfs: inode unlinked list needs to recalculate the inode CRC · ad868afd
      由 Dave Chinner 提交于 
      The inode unlinked list manipulations operate directly on the inode
buffer, and so bypass the inode CRC calculation mechanisms. Hence an
inode on the unlinked list has an invalid CRC. Fix this by
recalculating the CRC whenever we modify an unlinked list pointer in
an inode, ncluding during log recovery. This is trivial to do and
results in  unlinked list operations always leaving a consistent
inode in the buffer.

      xfs: fix log recovery transaction item reordering · 75406170
      由 Dave Chinner 提交于 
      There are several constraints that inode allocation and unlink
logging impose on log recovery. These all stem from the fact that
inode alloc/unlink are logged in buffers, but all other inode
changes are logged in inode items. Hence there are ordering
constraints that recovery must follow to ensure the correct result
occurs.

As it turns out, this ordering has been working mostly by chance
than good management. The existing code moves all buffers except
cancelled buffers to the head of the list, and everything else to
the tail of the list. The problem with this is that is interleaves
inode items with the buffer cancellation items, and hence whether
the inode item in an cancelled buffer gets replayed is essentially
left to chance.

Further, this ordering causes problems for log recovery when inode
CRCs are enabled. It typically replays the inode unlink buffer long before
it replays the inode core changes, and so the CRC recorded in an
unlink buffer is going to be invalid and hence any attempt to
validate the inode in the buffer is going to fail. Hence we really
need to enforce the ordering that the inode alloc/unlink code has
expected log recovery to have since inode chunk de-allocation was
introduced back in 2003...

      xfs: fix remote attribute invalidation for a leaf · ea929536
      由 Dave Chinner 提交于 
      When invalidating an attribute leaf block block, there might be
remote attributes that it points to. With the recent rework of the
remote attribute format, we have to make sure we calculate the
length of the attribute correctly. We aren't doing that in
xfs_attr3_leaf_inactive(), so fix it.

      xfs: rework dquot CRCs · bb9b8e86
      由 Dave Chinner 提交于 
      Calculating dquot CRCs when the backing buffer is written back just
doesn't work reliably. There are several places which manipulate
dquots directly in the buffers, and they don't calculate CRCs
appropriately, nor do they always set the buffer up to calculate
CRCs appropriately.

Firstly, if we log a dquot buffer (e.g. during allocation) it gets
logged without valid CRC, and so on recovery we end up with a dquot
that is not valid.

Secondly, if we recover/repair a dquot, we don't have a verifier
attached to the buffer and hence CRCs are not calculated on the way
down to disk.

Thirdly, calculating the CRC after we've changed the contents means
that if we re-read the dquot from the buffer, we cannot verify the
contents of the dquot are valid, as the CRC is invalid.

So, to avoid all the dquot CRC errors that are being detected by the
read verifier, change to using the same model as for inodes. That
is, dquot CRCs are calculated and written to the backing buffer at
the time the dquot is flushed to the backing buffer. If we modify
the dquot directly in the backing buffer, calculate the CRC
immediately after the modification is complete. Hence the dquot in
the on-disk buffer should always have a valid CRC.

      Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next · 143554ac
      由 David S. Miller 提交于 
      Conflicts:
	net/netfilter/nf_log.c

The conflict in nf_log.c is that in 'net' we added CONFIG_PROC_FS
protection around foo_proc_entry() calls to fix a build failure,
whereas in Pablo's tree a guard if() test around a call is
remove_proc_entry() was removed.  Trivially resolved.

Pablo Neira Ayuso says:

====================
The following patchset contains the first batch of
Netfilter/IPVS updates for your net-next tree, they are:

* Three patches with improvements and code refactorization
  for nfnetlink_queue, from Florian Westphal.

* FTP helper now parses replies without brackets, as RFC1123
  recommends, from Jeff Mahoney.

* Rise a warning to tell everyone about ULOG deprecation,
  NFLOG has been already in the kernel tree for long time
  and supersedes the old logging over netlink stub, from
  myself.

* Don't panic if we fail to load netfilter core framework,
  just bail out instead, from myself.

* Add cond_resched_rcu, used by IPVS to allow rescheduling
  while walking over big hashtables, from Simon Horman.

* Change type of IPVS sysctl_sync_qlen_max sysctl to avoid
  possible overflow, from Zhang Yanfei.

* Use strlcpy instead of strncpy to skip zeroing of already
  initialized area to write the extension names in ebtables,
  from Chen Gang.

* Use already existing per-cpu notrack object from xt_CT,
  from Eric Dumazet.

* Save explicit socket lookup in xt_socket now that we have
  early demux, also from Eric Dumazet.

      arch, mm: Remove tlb_fast_mode() · 29eb7782
      由 Peter Zijlstra 提交于 
      Since the introduction of preemptible mmu_gather TLB fast mode has been
broken. TLB fast mode relies on there being absolutely no concurrency;
it frees pages first and invalidates TLBs later.

However now we can get concurrency and stuff goes *bang*.

This patch removes all tlb_fast_mode() code; it was found the better
option vs trying to patch the hole by entangling tlb invalidation with
the scheduler.

      x86/PCI: Map PCI setup data with ioremap() so it can be in highmem · 65694c5a
      由 Matt Fleming 提交于 
      f9a37be0 ("x86: Use PCI setup data") added support for using PCI ROM
images from setup_data.  This used phys_to_virt(), which is not valid for
highmem addresses, and can cause a crash when booting a 32-bit kernel via
the EFI boot stub.

pcibios_add_device() assumes that the physical addresses stored in
setup_data are accessible via the direct kernel mapping, and that calling
phys_to_virt() is valid.  This isn't guaranteed to be true on x86 where the
direct mapping range is much smaller than on x86-64.

Calling phys_to_virt() on a highmem address results in the following:

 BUG: unable to handle kernel paging request at 39a3c198
 IP: [<c262be0f>] pcibios_add_device+0x2f/0x90
 ...
 Call Trace:
  [<c2370c73>] pci_device_add+0xe3/0x130

  [<c23b7203>] acpi_pci_root_add+0x312/0x42f
  ...

The solution is to use ioremap() instead of phys_to_virt() to map the
setup data into the kernel address space.
