ecryptfs_key_tfm Struct Reference

#include <ecryptfs_kernel.h>

Data Fields
struct crypto_blkcipher *	key_tfm
size_t	key_size
struct mutex	key_tfm_mutex
struct list_head	key_tfm_list
unsigned char	cipher_name [ECRYPTFS_MAX_CIPHER_NAME_SIZE+1]

Detailed Description

ecryptfs_key_tfm - Persistent key tfm : crypto API handle to the key : Key size in bytes : Mutex to ensure only one operation in eCryptfs is using the persistent TFM at any point in time : Handle to hang this off the module-wide TFM list : String name for the cipher for this TFM

Typically, eCryptfs will use the same ciphers repeatedly throughout the course of its operations. In order to avoid unnecessarily destroying and initializing the same cipher repeatedly, eCryptfs keeps a list of crypto API contexts around to use when needed.
