* crypto: rng - ensure that the RNG is ready before usingJason A. Donenfeld2017-07-281-2/+4
| | | | | | | | | | | Otherwise, we might be seeding the RNG using bad randomness, which is dangerous. The one use of this function from within the kernel -- not from userspace -- is being removed (keys/big_key), so that call site isn't relevant in assessing this.

* crypto: algif_aead - overhaul memory managementStephan Mueller2017-07-281-324/+442
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The updated memory management is described in the top part of the code. As one benefit of the changed memory management, the AIO and synchronous operation is now implemented in one common function. The AF_ALG operation uses the async kernel crypto API interface for each cipher operation. Thus, the only difference between the AIO and sync operation types visible from user space is: 1. the callback function to be invoked when the asynchronous operation is completed 2. whether to wait for the completion of the kernel crypto API operation or not The change includes the overhaul of the TX and RX SGL handling. The TX SGL holding the data sent from user space to the kernel is now dynamic similar to algif_skcipher. This dynamic nature allows a continuous operation of a thread sending data and a second thread receiving the data. These threads do not need to synchronize as the kernel processes as much data from the TX SGL to fill the RX SGL. The caller reading the data from the kernel defines the amount of data to be processed. Considering that the interface covers AEAD authenticating ciphers, the reader must provide the buffer in the correct size. Thus the reader defines the encryption size.

Thus, the only difference between the AIO and sync operation types visible from user space is: 1. the callback function to be invoked when the asynchronous operation is completed 2. whether to wait for the completion of the kernel crypto API operation or not In addition, the code structure is adjusted to match the structure of algif_aead for easier code assessment. The user space interface changed slightly as follows: the old AIO operation returned zero upon success and < 0 in case of an error to user space. As all other AF_ALG interfaces (including the sync skcipher interface) returned the number of processed bytes upon success and < 0 in case of an error, the new skcipher interface (regardless of AIO or sync) returns the number of processed bytes in case of success.

* hwrng: remember rng chosen by userHarald Freudenberger2017-07-181-2/+19
| | | | | | | | | | | | | | | When a user chooses a rng source via sysfs attribute this rng should be sticky, even when other sources with better quality to register. This patch introduces a simple way to remember the user's choice. This is reflected by a new sysfs attribute file 'rng_selected' which shows if the current rng has been chosen by userspace. The new attribute file shows '1' for user selected rng and '0' otherwise.

The device features hardware acceleration for the NIST standard P256 prime curve and supports the complete key life cycle from private key generation to ECDH key agreement. Random private key generation is supported internally within the device to ensure that the private key can never be known outside of the device. If the user wants to use its own private keys, the driver will fallback to the ecdh software implementation.

* crypto: authencesn - Fix digest_null crashHerbert Xu2017-07-181-0/+5
| | | | | | | | | | | | | | | | | When authencesn is used together with digest_null a crash will occur on the decrypt path. This is because normally we perform a special setup to preserve the ESN, but this is skipped if there is no authentication. However, on the post-authentication path it always expects the preservation to be in place, thus causing a crash when digest_null is used. This patch fixes this by also skipping the post-processing when there is no authentication. Fixes: 104880a6b470 ("crypto: authencesn - Convert to new AEAD...")
