Theodore Ts'o 5bbdcbbb39 fscrypt: make test_dummy_encryption require a keyring key
Currently, the test_dummy_encryption ext4 mount option, which exists
only to test encrypted I/O paths with xfstests, overrides all
per-inode encryption keys with a fixed key.

This change minimizes test_dummy_encryption-specific code path changes
by supplying a fake context for directories which are not encrypted
for use when creating new directories, files, or symlinks.  This
allows us to properly exercise the keyring lookup, derivation, and
context inheritance code paths.

Before mounting a file system using test_dummy_encryption, userspace
must execute the following shell commands:

    mode='\x00\x00\x00\x00'
    raw="$(printf ""\\\\x%02x"" $(seq 0 63))"
    if lscpu | grep "Byte Order" | grep -q Little ; then
        size='\x40\x00\x00\x00'
    else
        size='\x00\x00\x00\x40'
    fi
    key="${mode}${raw}${size}"
    keyctl new_session
    echo -n -e "${key}" | keyctl padd logon fscrypt:4242424242424242 @s
