eCryptfs: Check return of filemap_write_and_wait during fsync

2013-06-05T06:53:31Z

Error out of ecryptfs_fsync() if filemap_write_and_wait() fails. Signed-off-by: Tyler Hicks Cc: Paul Taysom Cc: Olof Johansson Cc: stable@vger.kernel.org # v3.6+

ecryptfs: fixed msync to flush data

2013-05-24T23:21:45Z

When msync is called on a memory mapped file, that data is not flushed to the disk. In Linux, msync calls fsync for the file. For ecryptfs, fsync just calls the lower level file system's fsync. Changed the ecryptfs fsync code to call filemap_write_and_wait before calling the lower level fsync.

Pull eCryptfs update from Tyler Hicks: "Improve performance when AES-NI (and most likely other crypto accelerators) is available by moving to the ablkcipher crypto API. The improvement is more apparent on faster storage devices. There's no noticeable change when hardware crypto is not available" * tag 'ecryptfs-3.10-rc1-ablkcipher' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs: eCryptfs: Use the ablkcipher crypto API

eCryptfs: Use the ablkcipher crypto API

2013-05-09T23:55:07Z

Make the switch from the blkcipher kernel crypto interface to the ablkcipher interface. encrypt_scatterlist() and decrypt_scatterlist() now use the ablkcipher interface but, from the eCryptfs standpoint, still treat the crypto operation as a synchronous operation. They submit the async request and then wait until the operation is finished before they return. Most of the changes are contained inside those two functions. Despite waiting for the completion of the crypto operation, the ablkcipher interface provides performance increases in most cases when used on AES-NI capable hardware.

Pull namespace bugfixes from Eric Biederman: "This is three simple fixes against 3.9-rc1. I have tested each of these fixes and verified they work correctly. The userns oops in key_change_session_keyring and the BUG_ON triggered by proc_ns_follow_link were found by Dave Jones. I am including the enhancement for mount to only trigger requests of filesystem modules here instead of delaying this for the 3.10 merge window because it is both trivial and the kind of change that tends to bit-rot if left untouched for two months." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: proc: Use nd_jump_link in proc_ns_follow_link fs: Limit sys_mount to only request filesystem modules (Part 2). fs: Limit sys_mount to only request filesystem modules. userns: Stop oopsing in key_change_session_keyring

Pull ecryptfs fixes from Tyler Hicks: "Minor code cleanups and new Kconfig option to disable /dev/ecryptfs The code cleanups fix up W=1 compiler warnings and some unnecessary checks. The new Kconfig option, defaulting to N, allows the rarely used eCryptfs kernel to userspace communication channel to be compiled out. This may be the first step in it being eventually removed." Hmm. I'm not sure whether these should be called "fixes", and it probably should have gone in the merge window.
