Hello,
While reviewing the new filesystem encryption code, I was confused by the
intended set of legal characters in the printable form of an encrypted filename.
According to the actual code in fs/crypto/fname.c, the legal characters are:
a-zA-Z0-9+,
Alternatively, according to the comment in the same file, the legal characters
are actually:
a-zA-Z0-9+_
Still alternatively, according to the design document[1], the legal characters
are actually:
a-zA-Z0-9+=
Which one is correct?
