The integrity_kernel_read() call in ima_calc_file_hash_tfm() can return a value of 0 before all bytes of the file are read. A value of 0 would normally indicate an EOF. This has been observed if a user process is causing a file appraisal and is terminated with a SIGTERM signal. The most common occurrence of seeing the problem is if a shutdown or systemd reload is initiated while files are being appraised. The problem is similar to commit <f5e1040196db> (ima: always return negative code for error) that fixed the problem in ima_calc_file_hash_atfm().
