Hi Roberto,
diff --git a/include/linux/integrity.h b/include/linux/integrity.h index 2271939c5c31..2ea0f2f65ab6 100644 --- a/include/linux/integrity.h +++ b/include/linux/integrity.h@@ -238,9 +241,12 @@ static enum integrity_status evm_verify_hmac(struct dentry *dentry, break; } - if (rc) - evm_status = (rc == -ENODATA) ? - INTEGRITY_NOXATTRS : INTEGRITY_FAIL; + if (rc) { + evm_status = INTEGRITY_NOXATTRS; + if (rc != -ENODATA) + evm_status = evm_immutable ? + INTEGRITY_FAIL_IMMUTABLE : INTEGRITY_FAIL;
The original code made an exception for the -ENODATA case. Using a ternary operator made sense in that case. Inverting the test makes the code less readable. Please use the standard "if" statement instead. thanks, Mimi
