fs: Fix file mode for O_TMPFILE

2013-08-05T14:24:10+00:00

O_TMPFILE, like O_CREAT, should respect the requested mode and should
create regular files.

This fixes two bugs: O_TMPFILE required privilege (because the mode
ended up as 000) and it produced bogus inodes with no type.

Safer ABI for O_TMPFILE

2013-07-13T09:26:37+00:00

[suggested by Rasmus Villemoes] make O_DIRECTORY | O_RDWR part of O_TMPFILE;
that will fail on old kernels in a lot more cases than what I came up with.
And make sure O_CREAT doesn't get there...

[O_TMPFILE] it's still short a few helpers, but infrastructure should be OK now...

make SYSCALL_DEFINE-generated wrappers do asmlinkage_protect

2013-03-04T03:58:33+00:00

... and switch i386 to HAVE_SYSCALL_WRAPPERS, killing open-coded
uses of asmlinkage_protect() in a bunch of syscalls.

killing the boilerplate crap around them.

Pull  more VFS bits from Al Viro:
 "Unfortunately, it looks like xattr series will have to wait until the
  next cycle ;-/

  This pile contains 9p cleanups and fixes (races in v9fs_fid_add()
  etc), fixup for nommu breakage in shmem.c, several cleanups and a bit
  more file_inode() work"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
  constify path_get/path_put and fs_struct.c stuff
  fix nommu breakage in shmem.c
  cache the value of file_inode() in struct file
  9p: if v9fs_fid_lookup() gets to asking server, it'd better have hashed dentry
  9p: make sure ->lookup() adds fid to the right dentry
  9p: untangle ->lookup() a bit
  9p: double iput() in ->lookup() if d_materialise_unique() fails
  9p: v9fs_fid_add() can't fail now
  v9fs: get rid of v9fs_dentry
  9p: turn fid->dlist into hlist
  9p: don't bother with private lock in ->d_fsdata; dentry->d_lock will do just fine
  more file_inode() open-coded instances
  selinux: opened file can't have NULL or negative ->f_path.dentry

(In the meantime, the hlist traversal macros have changed, so this
required a semantic conflict fixup for the newly hlistified fid->dlist)

Pull signal/compat fixes from Al Viro:
 "Fixes for several regressions introduced in the last signal.git pile,
  along with fixing bugs in truncate and ftruncate compat (on just about
  anything biarch at least one of those two had been done wrong)."

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal:
  compat: restore timerfd settime and gettime compat syscalls
  [regression] braino in "sparc: convert to ksignal"
  fix compat truncate/ftruncate
  switch lseek to COMPAT_SYSCALL_DEFINE
  lseek() and truncate() on sparc really need sign extension

cache the value of file_inode() in struct file

2013-03-02T00:48:30+00:00

Note that this thing does *not* contribute to inode refcount;
it's pinned down by dentry.
