From c2567f8ffa2704f6f2f81013e9a590deca5a865f Mon Sep 17 00:00:00 2001 From: Felix Beck Date: Wed, 5 Jan 2011 12:47:47 +0100 Subject: [PATCH] [S390] zcrypt: cope with cca restriction of cex3 The cca on the crypto adapter has a restriction in the size of the exponent if a key with a modulus bigger than 2048 bit is used. Thus in that case we have to avoid that the crypto device driver thinks the adapter is defect and sets it offline. Therfore a new member for the zcrypt_device struct called max_exp_bit_length is introduced. This will be set the first time the cca returns the error code function not implemented. If this is done with an adapter twice it will return -EINVAL. Signed-off-by: Felix Beck Signed-off-by: Martin Schwidefsky --- Reading git-format-patch failed
