Descriptions
When GELI reads a key file from standard input, it does not reuse the key file to initialize multiple providers at once resulting in the second and subsequent devices silently using a NULL key as the user key file. If a user only uses a key file without a user passphrase, the master key is encrypted with an empty key file allowing trivial recovery of the master key.
When GELI reads a key file from a standard input, it doesn't store it anywhere. If the user tries to initialize multiple providers at once, for the second and subsequent devices the standard input stream will be already empty. In this case, GELI silently uses a NULL key as the user key file. If the user used only a key file without a user passphrase, the master key was encrypted with an empty key file. This might not be noticed if the devices were also decrypted in a batch operation. Some GELI providers might be silently encrypted with a NULL key file.
