f2fs crypto: do not set encryption policy for non-directory by ioctl

2015-06-01T23:21:07+00:00

Encryption policy should only be set to an empty directory through ioctl, This patch add a judgement condition to verify type of the target inode to avoid incorrectly configuring for non-directory. Additionally, remove unneeded inline data conversion since regular or symlink file should not be processed here. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs crypto: allow setting encryption policy once

2015-06-01T23:21:06+00:00

This patch add XATTR_CREATE flag in setxattr when setting encryption context for inode. Without this flag the context could be set more than once, this should never happen. So, fix it. Signed-off-by: Chao Yu Signed-off-by: Jaegeuk Kim

f2fs crypto: add encryption policy and password salt support

2015-05-28T22:41:48+00:00

This patch adds encryption policy and password salt support through ioctl implementation. It adds three ioctls: F2FS_IOC_SET_ENCRYPTION_POLICY, F2FS_IOC_GET_ENCRYPTION_POLICY, F2FS_IOC_GET_ENCRYPTION_PWSALT, which use xattr operations. Note that, these definition and codes are taken from ext4 crypto support. For f2fs, xattr operations and on-disk flags for superblock and inode were changed.
