Subject: [PATCH] Fix test compile time warnings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
A number of tests cause compiler warnings like this:
hashcrypt_speed.c: In function ‘hash_data’:
hashcrypt_speed.c:101:2: warning: implicit declaration of function ‘alarm’ [-Wimplicit-function-declaration]
alarm(5);
^~~~~
hashcrypt_speed.c: In function ‘main’:
hashcrypt_speed.c:203:2: warning: implicit declaration of function ‘close’ [-Wimplicit-function-declaration]
close(fdc);
^~~~~
Fix by including unistd.h.

Subject: [PATCH] Adjust to recent user page API changes
4.6.0 basically renamed get_user_pages() to get_user_pages_remote() and
introduced a new get_user_pages() that always works on the current
task.[1] Distinguish the two APIs based on kernel version we're
compiling for.
Also, there seems to have been a massive cleansing of
page_cache_release(page) in favour of put_page(page)[2] which was an
alias for put_page(page)[3] since 2.6.0. Before that beginning with
2.4.0 both page_cache_release(page) and put_page(page) have been aliases
for __free_page(page). So using put_page() instead of
page_cache_release(page) will produce identical code for anything after
2.4.0.

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