eCryptfs: modified size of keysig in the ecryptfs_key_sig structure
The size of the 'keysig' array is incremented of one byte in order to make room for the NULL character. The 'keysig' variable is used, in the function ecryptfs_generate_key_packet_set(), to find an authentication token with the given signature and is printed a debug message if it cannot be retrieved.
