linux.git/fs/ecryptfs, branch v3.6-rc4

Merge tag 'ecryptfs-3.6-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs

2012-08-02T17:56:34+00:00

Pull ecryptfs fixes from Tyler Hicks:
 - Fixes a bug when the lower filesystem mount options include 'acl',
   but the eCryptfs mount options do not
 - Cleanups in the messaging code
 - Better handling of empty files in the lower filesystem to improve
   usability.  Failed file creations are now cleaned up and empty lower
   files are converted into eCryptfs during open().
 - The write-through cache changes are being reverted due to bugs that
   are not easy to fix.  Stability outweighs the performance
   enhancements here.
 - Improvement to the mount code to catch unsupported ciphers specified
   in the mount options

* tag 'ecryptfs-3.6-rc1-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs:
  eCryptfs: check for eCryptfs cipher support at mount
  eCryptfs: Revert to a writethrough cache model
  eCryptfs: Initialize empty lower files when opening them
  eCryptfs: Unlink lower inode when ecryptfs_create() fails
  eCryptfs: Make all miscdev functions use daemon ptr in file private_data
  eCryptfs: Remove unused messaging declarations and function
  eCryptfs: Copy up POSIX ACL and read-only flags from lower mount

ecryptfs_lookup_interpose(): allocate dentry_info first

less work on failure that way

sanitize ecryptfs_lookup()

2012-07-29T17:24:16+00:00

* ->lookup() never gets hit with . or ..
* dentry it gets is unhashed, so unless we had gone and hashed it ourselves, there's
no need to d_drop() the sucker.
* wrong name printed in one of the printks (NULL, in fact)

switch dentry_open() to struct path, make it grab references itself

ecryptfs: don't reinvent the wheels, please - use struct completion

2012-07-22T20:01:02+00:00

... and keep the sodding requests on stack - they are small enough.

don't expose I_NEW inodes via dentry->d_inode

2012-07-22T20:00:58+00:00

	d_instantiate(dentry, inode);
	unlock_new_inode(inode);

is a bad idea; do it the other way round...

VFS: Pass mount flags to sget()

2012-07-14T12:38:34+00:00

Pass mount flags to sget() so that it can use them in initialising a new
superblock before the set function is called.  They could also be passed to the
compare function.

don't pass nameidata * to vfs_create()

2012-07-14T12:34:50+00:00

all we want is a boolean flag, same as the method gets now

don't pass nameidata to ->create()

2012-07-14T12:34:47+00:00

boolean "does it have to be exclusive?" flag is passed instead;
Local filesystem should just ignore it - the object is guaranteed
not to be there yet.

stop passing nameidata to ->lookup()

2012-07-14T12:34:32+00:00

Just the flags; only NFS cares even about that, but there are
legitimate uses for such argument.  And getting rid of that
completely would require splitting ->lookup() into a couple
of methods (at least), so let's leave that alone for now...
