eCryptfs: fix lookup error for special files
When ecryptfs_lookup() is called against special files, eCryptfs generates the following errors because it tries to treat them like regular eCryptfs files. Error opening lower file for lower_dentry [0xffff810233a6f150], lower_mnt [0xffff810235bb4c80], and flags [0x8000] Error opening lower_file to read header region Error attempting to read the [user.ecryptfs] xattr from the lower file; return value = [-95] Valid metadata not found in header region or xattr region; treating file as unencrypted For instance, the problem can be reproduced by the steps below. # mkdir /root/crypt /mnt/crypt # mount -t ecryptfs /root/crypt /mnt/crypt # mknod /mnt/crypt/c0 c 0 0 # umount /mnt/crypt # mount -t ecryptfs /root/crypt /mnt/crypt # ls -l /mnt/crypt This patch fixes it by adding a check similar to directories and symlinks.
