eCryptfs: fix dentry handling on create error, unlink, and inode destroy
This patch corrects some erroneous dentry handling in eCryptfs. If there is a problem creating the lower file, then there is nothing that the persistent lower file can do to really help us. This patch makes a vfs_create() failure in the lower filesystem always lead to an unconditional do_create failure in eCryptfs. Under certain sequences of operations, the eCryptfs dentry can remain in the dcache after an unlink. This patch calls d_drop() on the eCryptfs dentry to correct this. eCryptfs has no business calling d_delete() directly on a lower filesystem's dentry. This patch removes the call to d_delete() on the lower persistent file's dentry in ecryptfs_destroy_inode(). (Thanks to David Kleikamp, Eric Sandeen, and Jeff Moyer for helping identify and resolve this issue) Signed-off-by: Michael Halcrow <mhalcrow@us.ibm.com> Cc: Dave Kleikamp <shaggy@austin.ibm.com> Cc: Eric Sandeen <sandeen@redhat.com> Cc: Jeff Moyer <jmoyer@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
