4Subject: [PATCH] Support skcipher in addition to ablkcipher API
5
6The ablkcipher API is being phased out[1]. The unified skcipher API
7seems to have made its entry with 4.3.[3, 4] By what can be seen from
8migration patches[1.ff.], it's a drop-in replacement.
9
10Also, deallocators such as crypto_free_skcipher() are NULL-safe now[2].
11
12Add a new header cipherapi.h to aid migration from ablkcipher to skcipher and
13retain support for old kernels. Make it decide which API to use and provide
14appropriate function calls and type definitions. Since the ablkcipher and
15skcipher APIs are so similar, those are mainly defines for corresponding
16pseudo-functions in namespace cryptodev_ derived directly from their API
17counterparts.
18
19Compiles and works (i.e. checks pass) with Debian testing 4.6.4 kernel
20as well as 4.8-rc2+ Linus git tree as of today. (Both require a fix for
21changed page access API[5].)
