    Subject[PATCH 5.13 284/800] crypto: testmgr - fix initialization of secret_size
    Date
    From: Hui Tang <tanghui20@huawei.com>

    [ Upstream commit 2d016672528a592ada5188e53ac746e1b8b7a978 ]

    Actual data length of the 'secret' is not equal to the 'secret_size'.

    Since the 'curve_id' has removed in the 'secret', the 'secret_size'
    should subtract the length of the 'curve_id'.

    Fixes: 6763f5ea2d9a ("crypto: ecdh - move curve_id of ECDH from ...")
