It is possible in rbd_get_num_segments() for an overflow to occur
when adding the offset and length. This is easily avoided.
Since the function returns an int and the one caller is already
prepared to handle errors, have it return -ERANGE if overflow would
occur.
The overflow check would not work if a zero-length request was
being tested, so short-circuit that case, returning 0 for the
number of segments required. (This condition might be avoided
elsewhere already, I don't know.)
Have the caller end the request if either an error or 0 is returned.
The returned value is passed to __blk_end_request_all(), meaning
a 0 length request is not treated an error.

In bio_chain_clone(), at the end of the function the bi_next field
of the tail of the new bio chain is nulled. This isn't necessary,
because if "tail" is non-null, its value will be the last bio
structure allocated at the top of the while loop in that function.
And before that structure is added to the end of the new chain, its
bi_next pointer is always made null.
While touching that function, clean a few other things:
- define each local variable on its own line
- move the definition of "tmp" to an inner scope
- move the modification of gfpmask closer to where it's used
- rearrange the logic that sets the chain's tail pointer

The rbd options don't really apply to the ceph client. So don't
store a pointer to it in the ceph_client structure, and put them
(a struct, not a pointer) into the rbd_dev structure proper.
Pass the rbd device structure to rbd_client_create() so it can
assign rbd_dev->rbdc if successful, and have it return an error code
instead of the rbd client pointer.

The only thing the on-disk snap_names_len field is needed is to
size the buffer allocated to hold a copy of the snapshot names
for an rbd image.
So don't bother saving it in the in-core rbd_image_header structure.
Just use a local variable to hold the required buffer size while
it's needed.
Move the code that actually copies the snapshot names up closer
to where the required length is saved.

rbd: simplify __rbd_init_snaps_header()
The problem is that a new rbd snapshot needs to go either after an
existing snapshot entry, or at the *end* of an rbd device's snapshot
list. As originally coded, it is placed at the beginning. This was
based on the assumption the list would be empty (so it wouldn't
matter), but in fact if multiple new snapshots are added to an empty
list in one shot the list will be non-empty after the first one is
added.

In the on-disk image header structure there is a field "block_name"
which represents what we now call the "object prefix" for an rbd
image. Rename this field "object_prefix" to be consistent with
modern usage.
This appears to be the only remaining vestige of the use of "block"
in symbols that represent objects in the rbd code.

A recent change to /sbin/mountall causes any trailing '/' character
in the "device" (or fs_spec) field in /etc/fstab to be stripped. As
a result, an entry for a ceph mount that intends to mount the root
of the name space ends up with now path portion, and the ceph mount
option processing code rejects this.
That is, an entry in /etc/fstab like:
cephserver:port:/ /mnt ceph defaults 0 0
provides to the ceph code just "cephserver:port:" as the "device,"
and that gets rejected.
Although this is a bug in /sbin/mountall, we can have the ceph mount
code support an empty/nonexistent path, interpreting it to mean the
root of the name space.
RFC 5952 offers recommendations for how to express IPv6 addresses,
and recommends the usage found in RFC 3986 (which specifies the
format for URI's) for representing both IPv4 and IPv6 addresses that
include port numbers. (See in particular the definition of
"authority" found in the Appendix of RFC 3986.)
According to those standards, no host specification will ever
contain a '/' character. As a result, it is sufficient to scan a
provided "device" from an /etc/fstab entry for the first '/'
character, and if it's found, treat that as the beginning of the
path. If no '/' character is present, we can treat the entire
string as the monitor host specification(s), and assume the path
to be the root of the name space. We'll still require a ':' to
separate the host portion from the (possibly empty) path portion.
This means that we can more formally define how ceph will interpret
the "device" it's provided when processing a mount request:
"device" will look like:
<server_spec>[,<server_spec>...]:[<path>]
where
<server_spec> is <ip>[:<port>]
<path> is optional, but if present must begin with '/'

Right now rbd_read_header() both reads the header object for an rbd
image and decodes its contents. It does this repeatedly if needed,
in order to ensure a complete and intact header is obtained.
Separate this process into two steps--reading of the raw header
data (in new function, rbd_dev_v1_header_read()) and separately
decoding its contents (in rbd_header_from_disk()). As a result,
the latter function no longer requires its allocated_snaps argument.

The only caller of rbd_header_from_disk() is rbd_read_header().
It passes as allocated_snaps the number of snapshots it will
have received from the server for the snapshot context that
rbd_header_from_disk() is to interpret. The first time through
it provides 0--mainly to extract the number of snapshots from
the snapshot context header--so that it can allocate an
appropriately-sized buffer to receive the entire snapshot
context from the server in a second request.
rbd_header_from_disk() will not fill in the array of snapshot ids
unless the number in the snapshot matches the number the caller
had allocated.
This patch adjusts that logic a little further to be more efficient.
rbd_read_header() doesn't even examine the snapshot context unless
the snapshot count (stored in header->total_snaps) matches the
number of snapshots allocated. So rbd_header_from_disk() doesn't
need to allocate or fill in the snapshot context field at all in
that case.

This just moves code around for the most part. It was pulled out as
a separate patch to avoid cluttering up some upcoming patches which
are more substantive. The point is basically to group everything
related to initializing the snapshot context together.
The only functional change is that rbd_header_from_disk() now
ensures the (in-core) header it is passed is zero-filled. This
allows a simpler error handling path in rbd_header_from_disk().

The purpose of __rbd_init_snaps_header() is to compare a new
snapshot context with an rbd device's list of existing snapshots.
It updates the list by adding any new snapshots or removing any
that are not present in the new snapshot context.
The code as written is a little confusing, because it traverses both
the existing snapshot list and the set of snapshots in the snapshot
context in reverse. This was done based on an assumption about
snapshots that is not true--namely that a duplicate snapshot name
could cause an error in intepreting things if they were not
processed in ascending order.
These precautions are not necessary, because:
- all snapshots are uniquely identified by their snapshot id
- a new snapshot cannot be created if the rbd device has another
snapshot with the same name
(It is furthermore not currently possible to rename a snapshot.)
This patch re-implements __rbd_init_snaps_header() so it passes
through both the existing snapshot list and the entries in the
snapshot context in forward order. It still does the same thing
as before, but I find the logic considerably easier to understand.
By going forward through the names in the snapshot context, there
is no longer a need for the rbd_prev_snap_name() helper function.

IBM reported a deadlock in select_parent(). This was found to be caused
by taking rename_lock when already locked when restarting the tree
traversal.
There are two cases when the traversal needs to be restarted:
1) concurrent d_move(); this can only happen when not already locked,
since taking rename_lock protects against concurrent d_move().
2) racing with final d_put() on child just at the moment of ascending
to parent; rename_lock doesn't protect against this rare race, so it
can happen when already locked.
Because of case 2, we need to be able to handle restarting the traversal
when rename_lock is already held. This patch fixes all three callers of
try_to_ascend().
IBM reported that the deadlock is gone with this patch.
[ I rewrote the patch to be smaller and just do the "goto again" if the
lock was already held, but credit goes to Miklos for the real work.

Sasha Levin has been running trinity in a KVM tools guest, and was able
to trigger the BUG_ON() at arch/x86/mm/pat.c:279 (verifying the range of
the memory type). The call trace showed that it was mtdchar_mmap() that
created an invalid remap_pfn_range().
The problem is that mtdchar_mmap() does various really odd and subtle
things with the vma page offset etc, and uses the wrong types (and the
wrong overflow) detection for it.
For example, the page offset may well be 32-bit on a 32-bit
architecture, but after shifting it up by PAGE_SHIFT, we need to use a
potentially 64-bit resource_size_t to correctly hold the full value.
Also, we need to check that the vma length plus offset doesn't overflow
before we check that it is smaller than the length of the mtdmap region.
This fixes things up and tries to make the code a bit easier to read.

commit c0357e975afdbbedab5c662d19bef865f02adc17 modified bnx2 to switch from
using ioremap/iounmap to pci_iomap/pci_iounmap. They missed a spot in the error
path of bnx2_init_one though. This patch just cleans that up.

Pull one more arm-soc bugfix from Olof Johansson:
"Here's a bugfix for orion5x. Without this, PCI doesn't initialize
properly because of too small coherent pool to cover the allocations
needed.
A similar fix has already been done on kirkwood."

Pull GPIO fix from Linus Walleij:
"A late GPIO fix: Roland Stigge found a problem in the LPC32xx driver
where a callback ignores one of its arguments. It needs to go into
stable too so sending this upstream immediately."

Pull two md bugfixes from NeilBrown:
"One (missing spinlock init) was only introduced recently. The other
has been present as long as raid10 has been supported, so is tagged
for -stable."
* tag 'md-3.6-fixes' of git://neil.brown.name/md:

Pull EDAC fixes from Mauro Carvalho Chehab:
"Three edac fixes at the memory enumeration logic:
- i3200_edac: Fixes a regression at the memory rank size, when the
memorias are dual-rank;
- i5000_edac: Fix a longstanding bug when calculating the memory
size: before Kernel 3.6, the memory size were right only
with one specific configuration;
- sb_edac: Fixes a bug since the initial release of the driver:
with 16GB DIMMs, there's an overflow at the memory size,
causing the number of pages per dimm (an unsigned value)
to have the highest bit equal to 1, effectively mangling
the memory size.
The third bug can potentially affect the error decoding logic as well."
* git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-edac:
sb_edac: Avoid overflow errors at memory size calculation
i5000: Fix the memory size calculation with 2R memories
i3200_edac: Fix memory rank size

The LAN8710/LAN8720 chips do have broken the "FlexPWR" smart power-saving
capability. Enabling it leads to the PHY not being able to detect Link when
cold-started without cable connected. Thus, make sure this is disabled.
