PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} macros were introduced *long* time
ago with promise that one day it will be possible to implement page
cache with bigger chunks than PAGE_SIZE.
This promise never materialized. And unlikely will.
We have many places where PAGE_CACHE_SIZE assumed to be equal to
PAGE_SIZE. And it's constant source of confusion on whether
PAGE_CACHE_* or PAGE_* constant should be used in a particular case,
especially on the border between fs and mm.
Global switching to PAGE_CACHE_SIZE != PAGE_SIZE would cause to much
breakage to be doable.
Let's stop pretending that pages in page cache are special. They are
not.
The changes are pretty straight-forward:
- <foo> << (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
- <foo> >> (PAGE_CACHE_SHIFT - PAGE_SHIFT) -> <foo>;
- PAGE_CACHE_{SIZE,SHIFT,MASK,ALIGN} -> PAGE_{SIZE,SHIFT,MASK,ALIGN};
- page_cache_get() -> get_page();
- page_cache_release() -> put_page();
This patch contains automated changes generated with coccinelle using
script below. For some reason, coccinelle doesn't patch header files.
I've called spatch for them manually.
The only adjustment after coccinelle is revert of changes to
PAGE_CAHCE_ALIGN definition: we are going to drop it later.
There are few places in the code where coccinelle didn't reach. I'll
fix them manually in a separate patch. Comments and documentation also
will be addressed with the separate patch.

Add an additional "name" field to struct xattr_handler. When the name
is set, the handler matches attributes with exactly that name. When the
prefix is set instead, the handler matches attributes with the given
prefix and with a non-empty suffix.
This patch should avoid bugs like the one fixed in commit c361016a in
the future.

The xattr_handler operations are currently all passed a file system
specific flags value which the operations can use to disambiguate between
different handlers; some file systems use that to distinguish the xattr
namespace, for example. In some oprations, it would be useful to also have
access to the handler prefix. To allow that, pass a pointer to the handler
to operations instead of the flags value alone.

On Mac OS X, HFS+ extended attributes are not namespaced. Since we want
to be compatible with OS X filesystems and yet still support the Linux
namespacing system, the hfsplus driver implements a special "osx"
namespace that is reported for any attribute that is not namespaced
on-disk. However, the current code for getting and setting these
unprefixed attributes is broken.
hfsplus_osx_setattr() and hfsplus_osx_getattr() are passed names that have
already had their "osx." prefixes stripped by the generic functions. The
functions first, quite correctly, check those names to make sure that they
aren't prefixed with a known namespace, which would allow namespace access
restrictions to be bypassed. However, the functions then prepend "osx."
to the name they're given before passing it on to hfsplus_getattr() and
hfsplus_setattr(). Not only does this cause the "osx." prefix to be
stored on-disk, defeating its purpose, it also breaks the check for the
special "com.apple.FinderInfo" attribute, which is reported for all files,
and as a consequence makes some userspace applications (e.g. GNU patch)
fail even when extended attributes are not otherwise in use.
There are five commits which have touched this particular code:
127e5f5ae51e ("hfsplus: rework functionality of getting, setting and deleting of extended attributes")
b168fff72109 ("hfsplus: use xattr handlers for removexattr")
bf29e886b242 ("hfsplus: correct usage of HFSPLUS_ATTR_MAX_STRLEN for non-English attributes")
fcacbd95e121 ("fs/hfsplus: move xattr_name allocation in hfsplus_getxattr()")
ec1bbd346f18 ("fs/hfsplus: move xattr_name allocation in hfsplus_setxattr()")
The first commit creates the functions to begin with. The namespace is
prepended by the original code, which I believe was correct at the time,
since hfsplus_?etattr() stripped the prefix if found. The second commit
removes this behavior from hfsplus_?etattr() and appears to have been
intended to also remove the prefixing from hfsplus_osx_?etattr().
However, what it actually does is remove a necessary strncpy() call
completely, breaking the osx namespace entirely. The third commit re-adds
the strncpy() call as it was originally, but doesn't mention it in its
commit message. The final two commits refactor the code and don't affect
its functionality.
This commit does what b168fff attempted to do (prevent the prefix from
being added), but does it properly, instead of passing in an empty buffer
(which is what b168fff actually did).

hfsplus_init_header_node()") introduced do_div() to xattr.c and the
warning below too.
As Geert remarked: "tmp" is "loff_t" which is "__kernel_loff_t", which
is "long long", i.e. signed, while include/asm-generic/div64.h compares
its type with "uint64_t". As inode sizes are positive, it should be
safe to change the type of "tmp" to "u64".

Zero newly allocated extents in the catalog tree if volume attributes
tell us to. Not doing so we risk getting the "unused node is not
erased" error. See kHFSUnusedNodeFix flag in Apple's source code for
reference.
There was a previous commit clearing the node when it is freed: commit
899bed05e9f6 ("hfsplus: fix issue with unzeroed unused b-tree nodes").
But it did not handle newly allocated extents (this patch fixes it).
And it zeroed nodes in all trees unconditionally which is an overkill.
This patch adds a condition and also switches to 'tree->node_size' as a
simpler method of getting the length to zero.

HFSPLUS_ATTR_MAX_STRLEN (=127) is the limit of attribute names for the
number of unicode character (UTF-16BE) storable in the HFS+ file system.
Almost all the current usage of it is wrong, in relation to NLS to
on-disk conversion.
Except for one use calling hfsplus_asc2uni (which should stay the same)
and its uses in calling hfsplus_uni2asc (which was corrected in the
earlier patch in this series concerning usage of hfsplus_uni2asc), all
the other uses are of the forms:
- char buffer[size]
- bound check: "if (namespace_adjusted_input_length > size) return failure;"
Conversion between on-disk unicode representation and NLS char strings
(in whichever direction) always needs to accommodate the worst-case NLS
conversion, so all char buffers of that size need to have a
NLS_MAX_CHARSET_SIZE x .
The bound checks are all wrong, since they compare nls_length derived
from strlen() to a unicode length limit.
It turns out that all the bound-checks do is to protect
hfsplus_asc2uni(), which can fail if the input is too large.
There is only one usage of it as far as attributes are concerned, in
hfsplus_attr_build_key(). It is in turn used by hfsplus_find_attr(),
hfsplus_create_attr(), hfsplus_delete_attr(). Thus making sure that
errors from hfsplus_asc2uni() is caught in hfsplus_attr_build_key() and
propagated is sufficient to replace all the bound checks.
Unpropagated errors from hfsplus_asc2uni() in the file catalog code was
addressed recently in an independent patch "hfsplus: fix longname
handling" by Sougata Santra.
Before this patch, trying to set a 55 CJK character (in a UTF-8 locale,
> 127/3=42) attribute plus user prefix fails with:
$ setfattr -n user.`cat testing-string` -v `cat testing-string` \
testing-string
setfattr: testing-string: Operation not supported
and retrieving a stored long attributes is particular ugly(!):
find /mnt/* -type f -exec getfattr -d {} \;
getfattr: /mnt/testing-string: Input/output error
with console log:
[268008.389781] hfsplus: unicode conversion failed
After the patch, both of the above works.
FYI, the test attribute string is prepared with:
echo -e -n \
"\xe9\x80\x99\xe6\x98\xaf\xe4\xb8\x80\xe5\x80\x8b\xe9\x9d\x9e\xe5" \
"\xb8\xb8\xe6\xbc\xab\xe9\x95\xb7\xe8\x80\x8c\xe6\xa5\xb5\xe5\x85" \

"\xbc\x8c\xe8\x80\x8c\xe5\x85\xb6\xe5\x94\xaf\xe4\xb8\x80\xe5\x89" \

"\xe7\x82\xba\xe4\xba\x86\xe6\xb8\xac\xe8\xa9\xa6\xe4\xbd\x9c\xe7" \
"\x94\xa8\xe3\x80\x82" | tr -d ' '
(= "pointlessly long attribute for testing", elaborate Chinese in
UTF-8 enoding).
However, it is not possible to set double the size (110 + 5 is still
under 127) in a UTF-8 locale:
$setfattr -n user.`cat testing-string testing-string` -v \
`cat testing-string testing-string` testing-string
setfattr: testing-string: Numerical result out of range
110 CJK char in UTF-8 is 330 bytes - the generic get/set attribute
system call code in linux/fs/xattr.c imposes a 255 byte limit. One can
use a combination of iconv to encode content, changing terminal locale
for viewing, and an nls=cp932/cp936/cp949/cp950 mount option to fully
use 127-unicode attribute in a double-byte locale.
Also, as an additional information, it is possible to (mis-)use unicode
half-width/full-width forms (U+FFxx) to write attributes which looks
like english but not actually ascii.
Thanks Anton Altaparmakov for reviewing the earlier ideas behind this
change.

This is a series of 3 patches which corrects issues in HFS+ concerning
the use of non-english file names and attributes. Names and attributes
are stored internally as UTF-16 units up to a fixed maximum size, and
convert to and from user-representation by NLS. The code incorrectly
assume that NLS string lengths are equal to unicode lengths, which is
only true for English ascii usage.
This patch (of 3):
The HFS Plus Volume Format specification (TN1150) states that file names
are stored internally as a maximum of 255 unicode characters, as defined
by The Unicode Standard, Version 2.0 [Unicode, Inc. ISBN
0-201-48345-9]. File names are converted by the NLS system on Linux
before presented to the user.
255 CJK characters converts to UTF-8 with 1 unicode character to up to 3
bytes, and to GB18030 with 1 unicode character to up to 4 bytes. Thus,
trying in a UTF-8 locale to list files with names of more than 85 CJK
characters results in:
$ ls /mnt
ls: reading directory /mnt: File name too long
The receiving buffer to hfsplus_uni2asc() needs to be 255 x
NLS_MAX_CHARSET_SIZE bytes, not 255 bytes as the code has always been.
Similar consideration applies to attributes, which are stored internally
as a maximum of 127 UTF-16BE units. See XNU source for an up-to-date
reference on attributes.
Strictly speaking, the maximum value of NLS_MAX_CHARSET_SIZE = 6 is not
attainable in the case of conversion to UTF-8, as going beyond 3 bytes
requires the use of surrogate pairs, i.e. consuming two input units.
Thanks Anton Altaparmakov for reviewing an earlier version of this
change.
This patch fixes all callers of hfsplus_uni2asc(), and also enables the
use of long non-English file names in HFS+. The getting and setting,
and general usage of long non-English attributes requires further
forthcoming work, in the following patches of this series.

When using the per-superblock xattr handlers permission checking is
done by the generic code. hfsplus just needs to check for the magic
osx attribute not to leak into protected namespaces.
Also given that the code was obviously copied from JFS the proper
attribution was missing.

ERROR: "__divdi3" [fs/hfsplus/hfsplus.ko] undefined!
Introduced by commit 099e9245e04d ("hfsplus: implement attributes file's
header node initialization code").
i_size_read() returns loff_t, which is long long, i.e. 64-bit. node_size
is size_t, which is either 32-bit or 64-bit. Hence
"i_size_read(attr_file) / node_size" is a 64-by-32 or 64-by-64 division,
causing (some versions of) gcc to emit a call to __divdi3().
Fortunately node_size is actually 16-bit, as the sole caller of
hfsplus_init_header_node() passes a u16. Hence change its type from
size_t to u16, and use do_div() to perform a 64-by-32 division.
Not seen in m68k/allmodconfig in -next, so it really depends on the
verion of gcc.

Implement functionality of creation AttributesFile metadata file on HFS+
volume in the case of absence of it.
It makes trying to open AttributesFile's B-tree during mount of HFS+
volume. If HFS+ volume hasn't AttributesFile then a pointer on
AttributesFile's B-tree keeps as NULL. Thereby, when it is discovered
absence of AttributesFile on HFS+ volume in the begin of xattr creation
operation then AttributesFile will be created.
The creation of AttributesFile will have success in the case of
availability (2 * clump) free blocks on HFS+ volume. Otherwise,
creation operation is ended with error (-ENOSPC).
