crypto: user - fix use_after_free of struct xxx_request

2018-12-07T06:15:00Z

All crypto_stats functions use the struct xxx_request for feeding stats, but in some case this structure could already be freed. For fixing this, the needed parameters (len and alg) will be stored before the request being executed.

crypto: user - convert all stats from u32 to u64

2018-12-07T06:15:00Z

All the 32-bit fields need to be 64-bit. In some cases, UINT32_MAX crypto operations can be done in seconds. Reported-by: Eric Biggers Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

2018-09-28T04:46:25Z

This patch implement a generic way to get statistics about all crypto usages. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: kpp - add get/set_flags helpers

2017-07-18T09:50:57Z

These helpers will be used for fallbacks to kpp software implementations. Signed-off-by: Tudor Ambarus Signed-off-by: Herbert Xu

crypto: kpp - assume key is already set in maxsize

2017-06-10T04:04:27Z

As of now, crypto_kpp_maxsize() can not be reached without successfully setting the key for the transformation. kpp algorithm implementations check if the key was set and then return the output buffer size required for the given key. Change the return type to unsigned int and always assume that this function is called after a successful setkey of the transformation. kpp algorithm implementations will remove the check if key is not NULL and directly return the max size.

crypto: kpp - constify buffer passed to crypto_kpp_set_secret()

2017-03-09T10:34:27Z

Constify the buffer passed to crypto_kpp_set_secret() and kpp_alg.set_secret, since it is never modified. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: doc - add KPP documentation

2016-12-13T23:38:06Z

Add the KPP API documentation to the kernel crypto API Sphinx documentation. This addition includes the documentation of the ECDH and DH helpers which are needed to create the approrpiate input data for the crypto_kpp_set_secret function.
