[PATCH v2] crypto/testmgr: don't copy from source IV too much

While the destination buffer 'iv' is MAX_IVLEN size, the source 'template[i].iv' could be smaller, thus memcpy may read read invalid memory. Use crypto_skcipher_ivsize() to get real ivsize and pass it to memcpy. Signed-off-by: Andrey Ryabinin --- crypto/testmgr.c | 5 +++-- 1 file changed, 3 ins
