hfsplus: use xattr handlers for removexattr

2014-01-31T19:44:39+00:00

hfsplus was already using the handlers for get and set operations,
and with the removal of can_set_xattr we've now allow operations that
wouldn't otherwise be allowed.

With this we can also centralize the special-casing of the osx.
attrs that don't have prefixes on disk in the osx xattr handlers.

hfsplus: remove can_set_xattr

2014-01-26T13:26:41+00:00

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.

hfsplus: Fix undefined __divdi3 in hfsplus_init_header_node()

2013-11-15T00:32:23+00:00

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.

hfsplus: implement attributes file creation functionality

2013-11-13T03:09:32+00:00

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).
