Tyler Hicks 081312e8c1 eCryptfs: Add getattr function ... commit f8f484d1b6 upstream. The i_blocks field of an eCryptfs inode cannot be trusted, but generic_fillattr() uses it to instantiate the blocks field of a stat() syscall when a filesystem doesn't implement its own getattr(). Users have noticed that the output of du is incorrect on newly created files. This patch creates ecryptfs_getattr() which calls into the lower filesystem's getattr() so that eCryptfs can use its kstat.blocks value after calling generic_fillattr(). It is important to note that the block count includes the eCryptfs metadata stored in the beginning of the lower file plus any padding used to fill an extent before encryption. https://bugs.launchpad.net/ecryptfs/+bug/390833 Reported-by: Dominic Sacré <dominic.sacre@gmx.de> Signed-off-by: Tyler Hicks <tyhicks@linux.vnet.ibm.com> Cc: Tim Gardner <timg@tpi.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>		2010-02-23 07:37:58 -08:00
