hfsplus: Fix potential buffer overflows

2012-05-07T15:53:38+00:00

commit 6f24f892871acc47b40dd594c63606a17c714f77 upstream.

Commit ec81aecb2966 ("hfs: fix a potential buffer overflow") fixed a few
potential buffer overflows in the hfs filesystem.  But as Timo Warns
pointed out, these changes also need to be made on the hfsplus
filesystem as well.

switch ->create() to umode_t

2012-01-04T03:54:53+00:00

vfs_create() ignores everything outside of 16bit subset of its
mode argument; switching it to umode_t is obviously equivalent
and it's the only caller of the method

switch vfs_mkdir() and ->mkdir() to umode_t

2012-01-04T03:54:53+00:00

vfs_mkdir() gets int, but immediately drops everything that might not
fit into umode_t and that's the only caller of ->mkdir()...

vfs: fix the stupidity with i_dentry in inode destructors

2012-01-04T03:52:40+00:00

Seeing that just about every destructor got that INIT_LIST_HEAD() copied into
it, there is no point whatsoever keeping this INIT_LIST_HEAD in inode_init_once();
the cost of taking it into inode_init_always() will be negligible for pipes
and sockets and negative for everything else.  Not to mention the removal of
boilerplate code from ->destroy_inode() instances...

vfs: mnt_drop_write_file()

2012-01-04T03:52:40+00:00

new helper (wrapper around mnt_drop_write()) to be used in pair with
mnt_want_write_file().

switch a bunch of places to mnt_want_write_file()

2012-01-04T03:52:35+00:00

it's both faster (in case when file has been opened for write) and cleaner.
