signal: allow to send any siginfo to itself
The idea is simple. We need to get the siginfo for each signal on
checkpointing dump, and then return it back on restore.
The first problem is that the kernel doesn't report complete siginfos to
userspace. In a signal handler the kernel strips SI_CODE from siginfo.
When a siginfo is received from signalfd, it has a different format with
fixed sizes of fields. The interface of signalfd was extended. If a
signalfd is created with the flag SFD_RAW, it returns siginfo in a raw
format.
rt_sigqueueinfo looks suitable for restoring signals, but it can't send
siginfo with a positive si_code, because these codes are reserved for
the kernel. In the real world each person has right to do anything with
himself, so I think a process should able to send any siginfo to itself.
This patch:
The kernel prevents sending of siginfo with positive si_code, because
these codes are reserved for kernel. I think we can allow a task to
send such a siginfo to itself. This operation should not be dangerous.
This functionality is required for restoring signals in
checkpoint/restart.

- set dirty flag on mount. If fs was initially dirty, warn user,

Checking extents overflow file.
Checking catalog file.
Unused node is not erased (node = 3111)

2. Copy linux kernel source tree (for example, 3.7-rc6 version) on
this partition under MacOS X.
3. Then switch to Linux and mount this prepared partition.
4. Execute `sudo rm -r` under prepared directory with linux kernel

hfsplus: add osx.* prefix for handling namespace of Mac OS X extended attributes
hfsplus: reworked support of extended attributes.
Current mainline implementation of hfsplus file system driver treats as
extended attributes only two fields (fdType and fdCreator) of user_info
field in file description record (struct hfsplus_cat_file). It is
possible to get or set only these two fields as extended attributes.
But HFS+ treats as com.apple.FinderInfo extended attribute an union of
user_info and finder_info fields as for file (struct hfsplus_cat_file)
as for folder (struct hfsplus_cat_folder). Moreover, current mainline
implementation of hfsplus file system driver doesn't support special
metadata file - attributes tree.
Mac OS X 10.4 and later support extended attributes by making use of the
HFS+ filesystem Attributes file B*-tree feature which allows for named
forks. Mac OS X supports only inline extended attributes, limiting
their size to 3802 bytes. Any regular file may have a list of extended
attributes. HFS+ supports an arbitrary number of named forks. Each
attribute is denoted by a name and the associated data. The name is a
null-terminated Unicode string. It is possible to list, to get, to set,
and to remove extended attributes from files or directories.
It exists some peculiarity during getting of extended attributes list by
means of getfattr utility. The getfattr utility expects prefix "user."
before any extended attribute's name. So, it ignores any names that
don't contained such prefix. Such behavior of getfattr utility results
in unexpected empty output of extended attributes list even in the case
when file (or folder) contains extended attributes. It needs to use
empty string as regular expression pattern for names matching (getfattr
--match="").
For support of extended attributes in HFS+:
1. It was added necessary on-disk layout declarations related to Attributes
tree into hfsplus_raw.h file.
2. It was added attributes.c file with implementation of functionality of
manipulation by records in Attributes tree.
3. It was reworked hfsplus_listxattr, hfsplus_getxattr, hfsplus_setxattr
functions in ioctl.c. Moreover, it was added hfsplus_removexattr method.
This patch:
Add osx.* prefix for handling namespace of Mac OS X extended attributes.

ocfs2: fix ocfs2_init_security_and_acl() to initialize acl correctly
We need to re-initialize the security for a new reflinked inode with its
parent dirs if it isn't specified to be preserved for ocfs2_reflink().
However, the code logic is broken at ocfs2_init_security_and_acl()
although ocfs2_init_security_get() succeed. As a result,
ocfs2_acl_init() does not involked and therefore the default ACL of
parent dir was missing on the new inode.
Note this was introduced by
9d8f13ba3 ("security: new
security_inode_init_security API adds function callback")
To reproduce:
set default ACL for the parent dir(ocfs2 in this case):
$ setfacl -m default:user:jeff:rwx ../ocfs2/
$ getfacl ../ocfs2/
# file: ../ocfs2/
# owner: jeff
# group: jeff
user::rwx
group::r-x
other::r-x
default:user::rwx
default:user:jeff:rwx
default:group::r-x
default:mask::rwx
default:other::r-x
$ touch a
$ getfacl a
# file: a
# owner: jeff
# group: jeff
user::rw-
group::rw-
other::r--
Before patching, create reflink file b from a, the user
default ACL entry(user:jeff:rwx)was missing:
$ ./ocfs2_reflink a b
$ getfacl b
# file: b
# owner: jeff
# group: jeff
user::rw-
group::rw-
other::r--
In this case, the end user can also observed an error message at syslog:
(ocfs2_reflink,3229,2):ocfs2_init_security_and_acl:7193 ERROR: status = 0
After applying this patch, create reflink file c from a:
$ ./ocfs2_reflink a c
$ getfacl c
# file: c
# owner: jeff
# group: jeff
user::rw-
user:jeff:rwx #effective:rw-

scripts/kernel-doc: handle struct member __aligned without numbers
Commit
ef5da59f1260 ("scripts/kernel-doc: handle struct member
__aligned") permits "char something [123] __aligned(8);".
However, by using \d we constraint ourselves with integers. This is not
always the case. In fact, it might be better to do char something[123]
__aligned(sizeof(u16));
For example, With wireless_dev defining:
u8 address[ETH_ALEN] __aligned(sizeof(u16));
With \d, scripts/kernel-doc erroneously says:
Warning(include/net/cfg80211.h:2618): Excess struct/union/enum/typedef member 'address' description in 'wireless_dev'
This is because the regex __aligned\s*\(\d+\) fails match at \d as
sizeof is used.
So replace \d with . to indicate "something" in kernel-doc to ignore
__aligned(SOMETHING) in structs. With this change, we can use integers
OR sizeof() or macros as we please.

mm: accelerate munlock() treatment of THP pages
munlock_vma_pages_range() was always incrementing addresses by PAGE_SIZE
at a time. When munlocking THP pages (or the huge zero page), this
resulted in taking the mm->page_table_lock 512 times in a row.
We can do better by making use of the page_mask returned by
follow_page_mask (for the huge zero page case), or the size of the page
munlock_vma_page() operated on (for the true THP page case).

sysrq: don't depend on weak undefined arrays to have an address that compares as NULL
When taking an address of an extern array, gcc quite naturally should be
able to say "an address of an object can never be NULL" and just
optimize away the test entirely.
However, the new alternate sysrq reset code (commit
154b7a489a5b:
"Input: sysrq - allow specifying alternate reset sequence") did exactly
that, and declared platform_sysrq_reset_seq[] as a weak array, and
expecting that testing the address of the array would show whether it
actually got linked against something or not.
And that doesn't work with all gcc versions. Clearly it works with
*some* versions of gcc, and maybe it's even supposed to work, but it
really is a very fragile concept.
So instead of testing the address of the weak variable, just create a
weak instance of that array that is empty. If some platform then has a
real platform_sysrq_reset_seq[] that overrides our weak one, the linker
will switch to that one, and it all works without any run-time
conditionals at all.

mm: do not grow the stack vma just because of an overrun on preceding vma
The stack vma is designed to grow automatically (marked with VM_GROWSUP
or VM_GROWSDOWN depending on architecture) when an access is made beyond
the existing boundary. However, particularly if you have not limited
your stack at all ("ulimit -s unlimited"), this can cause the stack to
grow even if the access was really just one past *another* segment.
And that's wrong, especially since we first grow the segment, but then
immediately later enforce the stack guard page on the last page of the
segment. So _despite_ first growing the stack segment as a result of
the access, the kernel will then make the access cause a SIGSEGV anyway!
So do the same logic as the guard page check does, and consider an
access to within one page of the next segment to be a bad access, rather
than growing the stack to abut the next segment.

ocfs2: fix possible use-after-free with AIO
Running AIO is pinning inode in memory using file reference. Once AIO

is the last thing we do with the inode.

vfs: kill FS_REVAL_DOT by adding a d_weak_revalidate dentry op
The following set of operations on a NFS client and server will cause
server# mkdir a
client# cd a
server# mv a a.bak
client# sleep 30 # (or whatever the dir attrcache timeout is)
client# stat .
stat: cannot stat `.': Stale NFS file handle
Obviously, we should not be getting an ESTALE error back there since the
inode still exists on the server. The problem is that the lookup code
will call d_revalidate on the dentry that "." refers to, because NFS has
FS_REVAL_DOT set.
nfs_lookup_revalidate will see that the parent directory has changed and
will try to reverify the dentry by redoing a LOOKUP. That of course
fails, so the lookup code returns ESTALE.
The problem here is that d_revalidate is really a bad fit for this case.
What we really want to know at this point is whether the inode is still
good or not, but we don't really care what name it goes by or whether
the dcache is still valid.
Add a new d_op->d_weak_revalidate operation and have complete_walk call
that instead of d_revalidate. The intent there is to allow for a
"weaker" d_revalidate that just checks to see whether the inode is still
good. This is also gives us an opportunity to kill off the FS_REVAL_DOT
special casing.

having it possibly called from RCU mode (it won't be)]

I do my best to document that if you care about limiting your
unprivileged users that when you have the user namespace support
enabled you will need to enable memory control groups.
There is a minor bug fix to prevent overflowing the stack if someone
creates way too many user namespaces.
The bulk of the changes are a continuation of the kuid/kgid push down
work through the filesystems. These changes make using uids and gids
typesafe which ensures that these filesystems are safe to use when
multiple user namespaces are in use. The filesystems converted for
3.9 are ceph, 9p, afs, ocfs2, gfs2, ncpfs, nfs, nfsd, and cifs. The
changes for these filesystems were a little more involved so I split
the changes into smaller hopefully obviously correct changes.
XFS is the only filesystem that remains. I was hoping I could get
that in this release so that user namespace support would be enabled
with an allyesconfig or an allmodconfig but it looks like the xfs
