linux-stable.git/drivers/staging/usbip, 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()
  fs: change return values from -EACCES to -EPERM
  fs/exec.c: make bprm_mm_init() static
  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()
  9p: split dropping the acls from v9fs_set_create_acl()
  ...

new helper: file_inode(file)

staging/usbip: Mark local functions as static (fix sparse warnings)

2013-02-15T23:12:40+00:00

sparse complains about these functions:
usbip/stub_dev.c:529:5: warning: symbol 'stub_pre_reset' was not declared. Should it be static?
usbip/stub_dev.c:535:5: warning: symbol 'stub_post_reset' was not declared. Should it be static?

-> add static keyword to silence the warning and make sparse happy.

staging: Remove unnecessary OOM messages

2013-02-11T18:10:33+00:00

alloc failures already get standardized OOM
messages and a dump_stack.

For the affected mallocs around these OOM messages:

Converted kzallocs with multiplies to kcalloc.
Converted kmallocs with multiplies to kmalloc_array.
Converted a kmalloc/strlen/strncpy to kstrdup.
Moved a spin_lock below a removed OOM message and
removed a now unnecessary spin_unlock.
Neatened alignment and whitespace.

staging: usbip: replace the interrupt safe spinlocks with common ones.

2013-01-22T17:00:10+00:00

On the client side, we have a virtual hcd driver, there actually no
hardware interrupts, so we do not need worry about race conditions
caused by irq with spinlock held. Turning off irq is not good for system
performance after all. Just replace them with a non interrupt safe
version.

staging: usbip: use interrupt safe spinlock to avoid potential deadlock.

2013-01-22T17:00:10+00:00

The function 'usbip_event_add()' may be called in interrupt context on
the stub side:
'stub_complete'->'stub_enqueue_ret_unlink'->'usbip_event_add'.
In this function it tries to get the lock 'ud->lock', so we should
disable irq when we get this lock in process context.

staging: usbip: userspace: suppress a bogus error

2013-01-07T20:38:54+00:00

If mkdir() of VHCI_STATE_PATH fails because the directory
already exists, that's not an error. This patch fixes
annoying "record connection" errors that would typically
come up on attach.

staging: usbip: userspace: add option to turn fortify on or off

2013-01-07T20:38:54+00:00

This comes handy when hacking with different cross
compilers, some of which may or may not have
_FORTIFY_SOURCE turned on by default. This patch
allows us to turn _FORTIFY_SOURCE on by specifying
--with-fortify option at configuration time (or
to turn it off by specifying --without-fortify).

If nothing is specified, default compiler behavior
is assumed.
