Pull crypto update from Herbert Xu:
 "API:

   - Add support for cipher output IVs in testmgr

Exynos Pseudo Random Number Generator
Required properties:
- compatible : Should be "samsung,exynos4-rng".
- reg : Specifies base physical address and size of the registers map.
- clocks : Phandle to clock-controller plus clock-specifier pair.
- clock-names : "secss" as a clock name.
Example:
rng@10830400 {
compatible = "samsung,exynos4-rng";
reg = <0x10830400 0x200>;
clocks = <&clock CLK_SSS>;
clock-names = "secss";

STMicroelectronics HW Random Number Generator
----------------------------------------------
Required parameters:
compatible : Should be "st,rng"
reg : Base address and size of IP's register map.
clocks : Phandle to device's clock (See: ../clocks/clock-bindings.txt)
Example:
rng@fee80000 {
compatible = "st,rng";
reg = <0xfee80000 0x1000>;

STMicroelectronics STM32 HW RNG
===============================
The STM32 hardware random number generator is a simple fixed purpose IP and
is fully separated from other crypto functions.
Required properties:
- compatible : Should be "st,stm32-rng"
- reg : Should be register base and length as documented in the datasheet
- interrupts : The designated IRQ line for the RNG
- clocks : The clock needed to enable the RNG
Example:
rng: rng@50060800 {
compatible = "st,stm32-rng";
reg = <0x50060800 0x400>;
interrupts = <80>;
clocks = <&rcc 0 38>;
};

@ -3,7 +3,7 @@ Introduction:
The hw_random framework is software that makes use of a
special hardware feature on your CPU or motherboard,
a Random Number Generator (RNG). The software has two parts:
a core providing the /dev/hw_random character device and its
a core providing the /dev/hwrng character device and its
sysfs support, plus a hardware-specific driver that plugs
into that core.

Those tools use /dev/hw_random to fill the kernel entropy pool,
Those tools use /dev/hwrng to fill the kernel entropy pool,
which is used internally and exported by the /dev/urandom and
/dev/random special files.
@ -32,13 +32,13 @@ Theory of operation:
The rng-tools package uses such tests in "rngd", and lets you
run them by hand with a "rngtest" utility.
/dev/hw_random is char device major 10, minor 183.
/dev/hwrng is char device major 10, minor 183.
CLASS DEVICE. There is a /sys/class/misc/hw_random node with
two unique attributes, "rng_available" and "rng_current". The
"rng_available" attribute lists the hardware-specific drivers
available, while "rng_current" lists the one which is currently
connected to /dev/hw_random. If your system has more than one
connected to /dev/hwrng. If your system has more than one
RNG available, you may change the one used by writing a name from
the list in "rng_available" into "rng_current".

/*
* Note for using key wrapping:
*
* * The result of the encryption operation is the ciphertext starting
* with the 2nd semiblock. The first semiblock is provided as the IV.
* The IV used to start the encryption operation is the default IV.
*
* * The input for the decryption is the first semiblock handed in as an
* IV. The ciphertext is the data starting with the 2nd semiblock. The
* return code of the decryption operation will be EBADMSG in case an
* integrity error occurs.
*
* To obtain the full result of an encryption as expected by SP800-38F, the
* caller must allocate a buffer of plaintext + 8 bytes:
*
* unsigned int datalen = ptlen + crypto_skcipher_ivsize(tfm);
* u8 data[datalen];
* u8 *iv = data;
* u8 *pt = data + crypto_skcipher_ivsize(tfm);
* <ensure that pt contains the plaintext of size ptlen>
* sg_init_one(&sg, ptdata, ptlen);
* skcipher_request_set_crypt(req, &sg, &sg, ptlen, iv);
*
* ==> After encryption, data now contains full KW result as per SP800-38F.
*
* In case of decryption, ciphertext now already has the expected length
* and must be segmented appropriately:
*
* unsigned int datalen = CTLEN;
* u8 data[datalen];
* <ensure that data contains full ciphertext>
* u8 *iv = data;
* u8 *ct = data + crypto_skcipher_ivsize(tfm);
* unsigned int ctlen = datalen - crypto_skcipher_ivsize(tfm);
* sg_init_one(&sg, ctdata, ctlen);
* skcipher_request_set_crypt(req, &sg, &sg, ptlen, iv);
*
* ==> After decryption (which hopefully does not return EBADMSG), the ct
* pointer now points to the plaintext of size ctlen.
*
* Note 2: KWP is not implemented as this would defy in-place operation.
* If somebody wants to wrap non-aligned data, he should simply pad
* the input with zeros to fill it up to the 8 byte boundary.
