函数名称:ma_calc_file_hash - calculate file hash* Asynchronous hash (ahash) allows using HW acceleration for calculating* a hash. ahash performance varies for different data sizes on different* crypto accelerators
函数原型:int ima_calc_file_hash(struct file *file, struct ima_digest_data *hash)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct file * | file | |
struct ima_digest_data * | hash |
414 | bool new_file_instance = TSC's on different sockets may be reset asynchronously.* This may cause the TSC ADJUST value on socket 0 to be NOT 0., modified_flags = false |
427 | 如果非f_mode按位与le is open for reading 的值则 |
431 | f等于dentry_open( & f_path, flags, f_cred) |
432 | 如果是错误则 |
437 | pr_info_ratelimited("Unable to reopen file for reading.\n") |
440 | modified_flags = true |
441 | 否则 |
442 | new_file_instance = true |
454 | rc等于ima_calc_file_shash(f, hash) |
455 | out : |
456 | 如果new_file_instance则fput(f) |
458 | 否则如果modified_flags则f_flags与等于le is open for reading 的反 |
460 | 返回:rc |
名称 | 描述 |
---|---|
ima_collect_measurement | ma_collect_measurement - collect file measurement* Calculate the file hash, if it doesn't already exist,* storing the measurement and i_version in the iint.* Must be called with iint->mutex held.* Return 0 on success, error code otherwise |
ima_eventdigest_init | This function writes the digest of an event (with size limit). |
