crypto: testmgr - fix length truncation with large page size
On PowerPC with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y, there is sometimes a crash in generate_random_aead_testvec(). The problem is that the generated test vectors use data lengths of up to about 2 * PAGE_SIZE, which is 128 KiB on PowerPC; however, the data length fields in the test vectors are 'unsigned short', so the lengths get truncated. Fix this by changing the relevant fields to 'unsigned int'. Fixes: 40153b10d91c ("crypto: testmgr - fuzz AEADs against their generic implementation") Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
