Date: Thu, 22 Apr 2010 12:10:06 -0700 From: Greg KH <gregkh@...e.de> To: linux-kernel@...r.kernel.org, stable@...nel.org Cc: stable-review@...nel.org, torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, Christian Pulvermacher <pulvermacher@....de>, Tyler Hicks <tyhicks@...ux.vnet.ibm.com> Subject: [155/197] ecryptfs: fix error code for missing xattrs in lower fs 2.6.32-stable review patch. If anyone has any objections, please let us know. ------------------ From: Christian Pulvermacher <pulvermacher@....de> commit cfce08c6bdfb20ade979284e55001ca1f100ed51 upstream. If the lower file system driver has extended attributes disabled, ecryptfs' own access functions return -ENOSYS instead of -EOPNOTSUPP. This breaks execution of programs in the ecryptfs mount, since the kernel expects the latter error when checking for security capabilities in xattrs.
