aead_request

函数名称：aead_request_alloc() - allocate request data structure*@tfm: cipher handle to be registered with the request*@gfp: memory allocation flag that is handed to kmalloc by the API call.* Allocate the request data structure that must be used with the AEAD

函数原型：static inline struct aead_request *aead_request_alloc(struct crypto_aead *tfm, gfp_t gfp)

返回类型：struct aead_request

参数：

类型	参数	名称
struct crypto_aead *	tfm
gfp_t	gfp

req等于kmalloc(req的长度 + rypto_aead_reqsize() - obtain size of the request data structure*@tfm: cipher handle* Return: number of bytes, gfp)

400

如果此条件成立可能性大(为编译器优化)(req)则aead_request_set_tfm() - update cipher handle reference in request*@req: request handle to be modified*@tfm: cipher handle that shall be added to the request handle* Allow the caller to replace the existing aead handle in the request
