commit 2db34e78f126c6001d79d3b66ab1abb482dc7caa upstream.

The AES-CTR glue code avoids calling into the blkcipher API for the
tail portion of the walk, by comparing the remainder of walk.nbytes
modulo AES_BLOCK_SIZE with the residual nbytes, and jumping straight
into the tail processing block if they are equal. This tail processing
block checks whether nbytes != 0, and does nothing otherwise.

However, in case of an allocation failure in the blkcipher layer, we
may enter this code with walk.nbytes == 0, while nbytes &gt; 0. In this
case, we should not dereference the source and destination pointers,
since they may be NULL. So instead of checking for nbytes != 0, check
for (walk.nbytes % AES_BLOCK_SIZE) != 0, which implies the former in
non-error conditions.

Fixes: 49788fe2a128 ("arm64/crypto: AES-ECB/CBC/CTR/XTS using ARMv8 NEON and Crypto Extensions")

<title>arm64: crypto: reduce priority of core AES cipher</title>

<content type='text'>
The asynchronous, merged implementations of AES in CBC, CTR and XTS
modes are preferred when available (i.e., when instantiating ablkciphers
explicitly). However, the synchronous core AES cipher combined with the
generic CBC mode implementation will produce a 'cbc(aes)' blkcipher that
is callable asynchronously as well. To prevent this implementation from
being used when the accelerated asynchronous implemenation is also
available, lower its priority to 250 (i.e., below the asynchronous
module's priority of 300).
