linux-stable.git/drivers/net/wireless/ray_cs.c, branch linux-3.9.y

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2013-02-27T04:16:07+00:00

Pull vfs pile (part one) from Al Viro:
 "Assorted stuff - cleaning namei.c up a bit, fixing ->d_name/->d_parent
  locking violations, etc.

  The most visible changes here are death of FS_REVAL_DOT (replaced with
  "has ->d_weak_revalidate()") and a new helper getting from struct file
  to inode.  Some bits of preparation to xattr method interface changes.

  Misc patches by various people sent this cycle *and* ocfs2 fixes from
  several cycles ago that should've been upstream right then.

  PS: the next vfs pile will be xattr stuff."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (46 commits)
  saner proc_get_inode() calling conventions
  proc: avoid extra pde_put() in proc_fill_super()

  ocfs2/dlm: use GFP_ATOMIC inside a spin_lock
  ocfs2: fix possible use-after-free with AIO
  ocfs2: Fix oops in ocfs2_fast_symlink_readpage() code path
  get_empty_filp()/alloc_file() leave both ->f_pos and ->f_version zero
  target: writev() on single-element vector is pointless
  export kernel_write(), convert open-coded instances
  fs: encode_fh: return FILEID_INVALID if invalid fid_type
  kill f_vfsmnt
  vfs: kill FS_REVAL_DOT by adding a d_weak_revalidate dentry op
  nfsd: handle vfs_getattr errors in acl protocol
  switch vfs_getattr() to struct path
  default SET_PERSONALITY() in linux/elf.h
  ceph: prepopulate inodes only when request is aborted
  d_hash_and_lookup(): export, switch open-coded instances
  9p: switch v9fs_set_create_acl() to inode+fid, do it before d_instantiate()

drivers/net/wireless: need consider the not '\0' terminated string.

2013-01-22T21:01:29+00:00

  in ray_cs.c:
    the a_current_ess_id is "Null terminated unless ESSID_SIZE long"
    so we need buffer it with '\0' firstly, before using strlen or %s.

  additional information:
    in drivers/net/wireless/rayctl.h:
      "NULL terminated unless 32 long" is a comment at line 616, 664
      ESSID_SIZE is 32, at line 190
    in include/uapi/linux/wireless.h:
      IW_ESSID_MAX_SIZE is also 32
    in drivers/net/wireless/ray_cs.c:
      use strncpy for it, without '\0' terminated, at line 639
      use memcpy for it, assume not '\0' terminated in line 1092..1097
      buffer it with '\0' firstly, before using %s, in line 2576, 2598..2600

wireless: Remove casts to same type

2012-06-06T16:31:33+00:00

Adding casts of objects to the same type is unnecessary
and confusing for a human reader.

For example, this cast:

        int y;
        int *p = (int *)&y;

I used the coccinelle script below to find and remove these
unnecessary casts.  I manually removed the conversions this
script produces of casts with __force, __iomem and __user.

@@
type T;
T *p;
@@

-       (T *)p
+       p

Neatened the mwifiex_deauthenticate_infra function which
was doing odd things with array pointers and not using
is_zero_ether_addr.

Remove all #inclusions of asm/system.h

2012-03-28T17:30:03+00:00

Remove all #inclusions of asm/system.h preparatory to splitting and killing
it.  Performed with the following command:

perl -p -i -e 's!^#\s*include\s*.*\n!!' `grep -Irl '^#\s*include\s*' *`

ray_cs: Fix array bounds warnings.

2011-11-26T20:41:29+00:00

rx_msg is defined to have a 1 entry array at the end, so gcc warns:

drivers/net/wireless/ray_cs.c: In function ‘rx_authenticate’:

Use a zero length array and rename to "ray_rx_msg" to make sure we hit all
of the necessary cases.

ray_cs: Use static const

2010-11-22T20:58:51+00:00

Using static const generally increases object text and decreases data size.
It also generally decreases overall object size.

  42607	   3581	   8536	  54724	   d5c4	drivers/net/wireless/ray_cs.o.new
