ima_collect

函数名称：ma_collect_modsig - Calculate the file hash without the appended signature.* Since the modsig is part of the file contents, the hash used in its signature* isn't the same one ordinarily calculated by IMA. Therefore PKCS7 code

函数原型：void ima_collect_modsig(struct modsig *modsig, const void *buf, loff_t size)

返回类型：void

参数：

类型	参数	名称
struct modsig *	modsig
const void *	buf
loff_t	size

125

size减等于* This is what will go to the measurement list if the template requires * storing the signature.加strlen - Find the length of a string*@s: The string to be sized加sizeof(structmodule_signature)

127

rc等于pkcs7_supply_detached_data(pkcs7_msg, buf, size)

128

如果rc则返回

132

rc等于pkcs7_get_digest(pkcs7_msg, & This digest will go in the 'd-modsig' field of the IMA template. , & digest_size, & hash_algo)
