This error can be reproduced by the following code compiled as ko on a
system with kasan enabled:

#include <linux/module.h>
#include <linux/crypto.h>
#include <crypto/hash.h>
#include <crypto/poly1305.h>

char test_data[] = "\x00\x01\x02\x03\x04\x05\x06\x07"
"\x08\x09\x0a\x0b\x0c\x0d\x0e\x0f"
"\x10\x11\x12\x13\x14\x15\x16\x17"
"\x18\x19\x1a\x1b\x1c\x1d\x1e";

int init(void)
{
struct crypto_shash *tfm = NULL;
char *data = NULL, *out = NULL;

tfm = crypto_alloc_shash("poly1305", 0, 0);
data = kmalloc(POLY1305_KEY_SIZE - 1, GFP_KERNEL);
out = kmalloc(POLY1305_DIGEST_SIZE, GFP_KERNEL);
memcpy(data, test_data, POLY1305_KEY_SIZE - 1);
crypto_shash_tfm_digest(tfm, data, POLY1305_KEY_SIZE - 1, out);

kfree(data);
kfree(out);
return 0;
}

void deinit(void)
{
}

module_init(init)
module_exit(deinit)
MODULE_LICENSE("GPL");

The root cause of the bug sits in neon_poly1305_blocks. The logic
neon_poly1305_blocks() performed is that if it was called with both s[]
and r[] uninitialized, it will first try to initialize them with the
data from the first "block" that it believed to be 32 bytes in length.
First 16 bytes are used as the key and the next 16 bytes for s[]. This
would lead to the aforementioned read out-of-bound. However, after
calling poly1305_init_arch(), only 16 bytes were deducted from the input
and s[] is initialized yet again with the following 16 bytes. The second
initialization of s[] is certainly redundent which indicates that the
first initialization should be for r[] only.

This patch fixes the issue by calling poly1305_init_arm64() instead of
poly1305_init_arch(). This is also the implementation for the same
algorithm on arm platform.
