Make sure that when we publish the crypt_data we access the memory cache of the tablespace crypt_data. Make sure that crypt_data is stored whenever it is really needed. All this is not yet enough in my opinion because: sql/encryption.cc has DBUG_ASSERT(scheme->type == 1) i.e. crypt_data->type == CRYPT_SCHEME_1 However, for InnoDB point of view we have global crypt_data for every tablespace. When we change variables on crypt_data we take mutex. However, when we use crypt_data for encryption/decryption we use pointer to this global structure and no mutex to protect against changes on crypt_data. Tablespace encryption starts in fil_crypt_start_encrypting_space from crypt_data that has crypt_data->type = CRYPT_SCHEME_UNENCRYPTED and later we write page 0 CRYPT_SCHEME_1 and finally whe publish that to memory cache.
