Roberto Sassu f375bcf69f ima: Fix memory leak in __ima_inode_hash() ... commit 8c1d6a050a0f16e0a9d32eaf53b965c77279c6f8 upstream. Commit f3cc6b25dc ("ima: always measure and audit files in policy") lets measurement or audit happen even if the file digest cannot be calculated. As a result, iint->ima_hash could have been allocated despite ima_collect_measurement() returning an error. Since ima_hash belongs to a temporary inode metadata structure, declared at the beginning of __ima_inode_hash(), just add a kfree() call if ima_collect_measurement() returns an error different from -ENOMEM (in that case, ima_hash should not have been allocated).
